Snippet:

30 Million Purse to be Awarded to Winners

SANTA MONICA, Calif., September 13, 2007 – The X PRIZE Foundation and Google Inc. (NASDAQ: GOOG) today announced the Google Lunar X PRIZE, a robotic race to the Moon to win a remarkable $30 million prize purse. Private companies from around the world will compete to land a privately funded robotic rover on the Moon that is capable of completing several mission objectives, including roaming the lunar surface for at least 500 meters and sending video, images and data back to the Earth.

Well thats disappointing. Hardly what I would call Pardign shifting... I would have been more impressed with an orbital MANNED race than a lunar robot. Quite frankly I find this disappointing news...

Yeah, I can't say I'm too thrilled.  Make no mistake, it will be cool to watch but it won't do anything to the industry like the first XPrize did.  Think about it, a contestant will concentrate on building the lander/rover then buy a ride on an already existing rocket.  What exactly will that accomplish?

I have to give the prize organizers some credit - they do have a deadline, which is always good, but they also have an extension to the deadline at a lower funding level. When I was running the CATS Prize, we had a deadline, but many of the contestants believed that the deadline would be extended, and so they didn't believe us when we told them that it was fixed. Several competitors told us that if we had extended the deadline by a month, they would have launched rockets into space. None of them ever actually launched, though.

You have to crawl before you can walk man.

The only other space related competition was to get a vehichle into space on a suborbital mission. That required so much money and technical know-how that only one of the teams actually came close to it and actually won it by investing over $20 million to win 1/2 of the investment back and in the process hopefully jump start an industry. Getting anything to the moon will require 15 times the amount of fuel/speed.

Besides, think of the public sector involvement. What better way to reinvigorate the general public than to have a little rover with a camera sending back video as the rover approaches Tranquility Base.....  Maybe even have the rover with a robotic arm to lift the fallen American Flag and place it in a holster built into the rover itself so it will forever more be standing....

Well that's what I would propose if I were designing a mission.  hehe

With only 5 years time, some drastic hardware developments would need to be done. First of all, an existing rocket would have to be used for launch from earth. I don't know what the rules say about this. The 20 million prize money (for the winner) then is quite small for that. Tell me again about those Russian sub launched missiles...

Anything that's done in the private sector in space beyond GSO comsats and LEO photosats is a paradigm shift.  Incremental changes create something to build on.  Apollo taught us that radical changes can have no coattails. 10's of $M to orbit people or 10's of $B to put people on Mars and back would have been great too.  But vision of a sustained human presence in space should not be disappointed.

Where is the requirement that spending on the mission must be constrained to $30 million? What if a competitor uses secondary markets to make up any costs over $30 million?

Don't get me wrong, I hope it does exactly what you say however I just don't see it inspiring anyone in the general public... Having a manned private vehicle make orbit would probably get a lot of attention especially when sold as Not being done by NASA... putting a robot on the moon to take a few pictures will make the front page (maybe) for a day and then no one will care except those of us intimately involved and interested already.

you want an inspiring race??? get a consortium (google, microsoft etc) and offer 100m to put a manned reusable ship in orbit in 5 years. To me.. that would be impressive.

either way, I do wish anyone particpating the best of luck and I will watch as it unfolds as well, I just don't think it will be of any interest to the general populace. From that perspective I am disappointed.

In the first X Prize, it cost at least $25M (plus all of the $ spent by non-winners) to win $10M, but now we have Virgin Galactic and a whole bunch of hardware start-ups.  How much capital is $30M going to bring?

Todd, love the idea of landing near Tranquility Base.  Prove the naysayers wrong once and for all.  However, precision landing might be a costly luxury.

I don't consider that disappointing at all. This is not only incentive for privateers to develop their own landing, deployment, and robotic hardware, but means of remote control (real time with delay, programmed, or even AI-based). Not to mention what type of unique landing craft designs, propulsion systems, and rover/exploration hardware and electronics might be created.
And who knows if some original and radical hardware could end up being successful?

IMO, future 'manned' solar system exploration will be done with heavy emphasis on robotic systems for initial scouting and pathfinding (and 'grunt work' when necessary), both for safety and to allow the human part of the missions to allocate their resources and intelligence where it's most appropriate to provide the best overall benefits.

Okay, let's assume a 8.5 million dollar Falcon Ie launch, say it places 800 kg to LEO. From there we have 6 km/s to the lunar surface.
Let's use two 3 km/s stages, both having an ISP of 320 s, meaning a mass ratio of 2.55. We can round off to 2.67 or 8/3 to account for tank and thruster mass, and get the payload mass which is 3/8*3/8*800 kg ~= 130 kg.

Agreed, but to look back on most major "First-to-do"/technical achievement prizes, the amount of the prize money itself is much less important to any entrants than actually *winning* (and for most entrants the costs usually overwhelm the prize amount anyway).

I can't see what kind of a market that this prize is hoping to foster.

Unless there is sponsorship, no one's going to make money off of this. If it was doable even near that price, AMSAT probably would have had a Lunar OSCAR by now.

I doubt any serious teams will even bother trying. Maybe X-Prize can get that Discraft guy to sign up again.

That would be quite the accomplishment.   Then again the Sojourner rover was what again?  Under 15 kg?


Oh man, watch the announcement video on XPrize.org.  

For a private effort, they seem to love using Constellation footage.   :laugh:

Right off the top of my head I can think of a rather large one - a large stepping stone to develop and start perfecting cost-effective commercial access (for other than the huge govt-funded mega-corp's) to the moon and asteroids.

I can see if NASA has interest in commercial resupply of the moon base, a few million/billionaires might fund a team with the hope of developing the necessary capabilities. Like SS1 begot SS2 , a small ( tiny ) lunar lander/rover could lead to a larger cargo lander.

As far as commercial manned orbital competition, don't forget Bigelow's America's Space Prize.

And it seems they think the only available launcher for the rover can be Ares V... which would put the mission at a price tag of at least 1 billion USD and with a NET launch date of 2020...

Hey, somebody revive Transorbital, they at least had a plan and the powerpoint presentation to prove it.

http://www.transorbital.net/bluespartan/index.php

*15mln For the first landing of a rover, plus driving somewhere
*5mln for second place
*Special bonus for finding water and surviving the night

Maybe Pillinger can sell the plans for his Beagle 2 rover....

Probably a result of being rushed for time, rather than funding (well in advance) a studio to create some unique 3D vehicle and launch video. (X-Prize apparently doesn't have the most organized management for making sure all the PR and organizational details for future events are covered.)

Let's use two 3 km/s stages, both having an ISP of 320 s, meaning a mass ratio of 2.55. We can round off to 2.67 or 8/3 to account for tank and thruster mass, and get the payload mass which is 3/8*3/8*800 kg ~= 130 kg.

Your calculations are not describing a realistic scenario. A two stage scenario would use just one stage for the Earth departure and a second stage for course-corrections, lunar orbit insertion and the landing on the moon. The ISP of 320s for the first stage (that does not need to be restarted or endure a long time in space) is realistic, for the second (restartable) stage a lower ISP should be assumed, especially considering its rather small mass and the fact that this mission will probably not focus on high-performance stages, rather on getting the cargo save to the surface. Let's assume an ISP of 300, which corresponds favourably to Apollo's LM descent stage. A 1:10 propellant/dry mass ratio for the first stage and a 1:7 propellant/dry mass ration (both without cargo) are reasonable assumptions as well. The first stage needs to do a minimum of 3.2 km/s while the second stage needs to do a minimum of 2.8km/s. However these are minimum numbers and do not include any margins. Realistically we need to assume about 3.6km/s for the first stage and 3.2km/s for the second stage.

Considering the above, a 130 kg payload (that is rover, structure in that the rover is placed, avionics, transmitter, etc.) requires a second stage (descent stage) with a weight of 500 kg (dry weight approximately 80kg. The first stage would then be required to approximately 2400 kg. LEO weight would be approximately 3 metric tons.

I personally think any proposal that wants to win this XPrice needs to take a minimum cost and minimum size approach. That is they have to start thinking about the smallest possible rover that could achieve 500m "roving" on the lunar surface and then calculate backwards to what the LEO payload would be. I personally think a rover needs to be at least 10 kg to effectively be able to compete the 500m on the lunar surface. In addition structure for the payload, transmitter, computers and avionics on the descent stage will at least require another 20kg effective payload mass. Assuming 30kg effective payload and the ISPs and fuel/dry mass assumptions for the stages mentioned above, the payload a team needs to get into LEO would be at a minimum 400-500 kg. There are several launch options currently available for such a small-sat: Disregarding piggybag-rides on large rockets, a 500kg payload can be launched on Rockot as one of the prime payloads on a multi-payload mission for a launch fee between 6-10 million USD (depending on the other payloads, time pressure, USD exchange rate developments etc.). Assuming that a team (probably a university team) can put together the rover, the transmitter station on the descent stage and the two stages, it is reasonable to assume that such a mission can be pulled of with much less than 30 millions - therefore I believe this XPrize is more or less a race, a race between university teams (who are able to get money upfront) were there really is only one winner and all others will have "wasted" money for nothing.

Yeah...there was this bit from the Google press release:

Quote
Strategic alliances that support this new competition include:
• Space Exploration Technologies (SpaceX), run by entrepreneur and X PRIZE Foundation Trustee Elon Musk, which is offering competing teams an in-kind contribution, lowering the cost of its Falcon Launch Vehicle. SpaceX is the first preferred launch provider for this competition;
• The Allen Telescope Array (ATA), operated by the SETI Institute, will serve as a preferred downlink provider for communications from the Moon to the Earth; operated by SETI, which will provide downlink services at no cost to competing teams;
• The Saint Louis Science Center serves as the Foundation’s official education partner and the coordinator of an international network of museums and science centers; and
• The International Space University (ISU), based in Strasbourg, France, will conduct international team outreach and facilitate an unbiased judging committee.

Elon Musk believes that falcon 1 is adequate for this mission. He talks of drop tanks on a lunar lander. There would only be one and a half stages in that case.

I have noticed that Spirit and Opportunity have attracted A LOT of public attention.  At present a smaller portion of the Lunar surface has been explored in detail than the Mars surface.  Continuing robotic exploration of the Moon (Ice at the south pole?) can attract both public and research interest.  

Bigelow's plan is to entice smaller nations with cost effective orbital research on his space stations.  This includes nations which have spent $ 1 Billion dollars on the ISS for ZILCH in terms of research results.  This lunar technology will allow these same nations to participate in deep space exploration (nearly as interesting as the Mars rovers) for $20 to $50 Million for each follow on lunar rover.  This is an interesting market!

Sponsorship of course is also a real factor as lunar rovers can be more interesting to watch than many sports events.

They want 7 million USD for the normal Falcon 1 and 8.5 million USD for the Falcon 1e - they claim Falcon 1 has a payload capacity to LEO of 650 kg, so I assume 1e would have a payload capacity of 800kg. Still, Falcon 1 needs to successfully fly first and show some reliability, before an XPrize team should reasonably think about it launching their rover on a mission to the moon which in itself is already highly risky and complicated. There are enough alternatives in the world that would be comparably priced, especially if such a team would come up with a proposal that has a lower weight than Falcon 1's capacity (under 500kg) or obviously if the proposal requires more payload capacity to LEO.

It is not fostering any market. Nobody is mentioning that it is designed to do so.

As outlined above, that is not correct. It is entirely possible to pull of a mission at the cost or below the cost of the price money. The problem of course is that you have to pre-fund your (extremely risky) endevour. And in that money categories we are talking about (10million+) it is hard to find people giving you the money other than governments. I see that the most likely competitors are student groups at universities - it does not have to be expensive to build a rover and a descent stage during two semesters - of course at some point each team will have to ask itself how they should come up with the costs for launching their payload into orbit.

Quote

As mentioned above, other than teams from various universities I dont't think anybody will try to win this X-Prize. There is no business prospect or money in it for the private industry and you can't entice investors into such a project like you actually could do with a good proposal for suborbital flights.

Yep, it was just a "one line" favourable estimate. Realistically the lunar paload could be tens of kg:s with a Falcon 1e.
There are quite high-isp storable propellant engines and some are even throttlable. 320 was probably pushing it too much though. Nozzle sizes might make the dry weight big too, which is not nice.

Assuming that a team (probably a university team) can put together the rover, the transmitter station on the descent stage and the two stages, it is reasonable to assume that such a mission can be pulled of with much less than 30 millions - therefore I believe this XPrize is more or less a race, a race between university teams (who are able to get money upfront) were there really is only one winner and all others will have "wasted" money for nothing.

10 kg rover minimum mass, not necessarily. You could have over a week of time if you arrive early in the lunar day, and you'd have constant sunlight (angle would change though). It pays off to spend considerable money to lighten up this thing.
In ten days it's 50 meters per day. Using 4 hours of every day for debugging and navigation planning you have 50 meters in 20 hours and 2.5 meters per hour. The speed ain't staggering. :) It's possible to have the rover be relatively unautonomous, either have more logic at the landing station or then completely script all driving commands from earth as the delay is just seconds. This was done with the Lunakhods.

I have noticed that Spirit and Opportunity have attracted A LOT of public attention.  At present a smaller portion of the Lunar surface has been explored in detail than the Mars surface.  

No, that's not true. There were six manned lunar landings in Apollo, plus various Surveyor and Lunakhod rovers.

There have been five successful Mars landings (Viking 1, Viking 2, Pathfinder/Sojourner, Spirit and Opportunity.)

Apollos 15, 16, and 17 each covered more ground than Spirit and Opportunity have to date.

There was a proposal from SSTL for a very low delta-v luna transfer, I'm trying to dig up the details but I'm drawing a blank so far.

Here is some detail from wikipedia: Low Energy Transfers

"The transfer used by Hiten is a revolutionary new type of low energy transfer to the Moon derived from Weak Stability Boundary Theory. See Capture Dynamics and Chaotic Motions in Celestial Mechanics. Unlike the standard three day route to the Moon, called a Hohmann transfer, this low energy route does not require large rocket engines to slow down to be captured into lunar orbit. It also takes three months instead of three days."

Ummm using a high ISP ION engine a patient team could crash a probe into the moon. Attempt a hard landing (refer to NASA Ranger 5 ) with a large solid sky crane attached to the rover which is stored inside of air bags (refer to the mars rovers).

Could be done and the rover need not be a light weight, nor does the probe need to obtain lunar orbit before decending... Direct decent uses less fuel.

So who wants to give me the $$$ and a pegasus to try it with?

There's no private business to be done on the moon right now. Why should private companies bother to prospect it when they know several governments are about to do it for them.

As for technology that needs to be developed: it's not the development, it's the price tag.  If you're going to have to use a low thrust option to get there you might get stuck having to build an ion engine.  Not many of those in private hands right now. The long time to get to the moon will mean more expense of having to keep someone on payroll monitoring it until it gets there. RAD hardened circuits. Landing will require thrusters. Everything will have to be tested, and there will have to be redundancy built into it or someone is out a lot of money.

8 million of it will go to the launcher alone. That leaves 12 million to build, test, integrate, deliver, and control a lunar spacecraft and rover. And for the sponsor, great odds of having your name attached to a dismal failure vs. minor rewards of winning a prize no one but alt.space fans will pay attention to.

Off the top of my head, I'd say launch on a collision trajectory using a Dnepr with ST-1 upper stage, using the second stage of the ST-1 as a coast/crasher stage. Then use small hypergolic thrusters on a lander to complete the flight. Deploy a small rover, the size of a toy remote control car, from the lander.

I'm not sure of costs, but I think that should be profitable. I'm allowing about 20 million dollars for launch (not sure if this is right, but I seem to remember reading that Dnepr launches cost about $13 million (I could be wrong), and assuming that the upper stage wouldn't cost as much as the carrier rocket). Not much money would be left for the spacecraft. I'm allowing about $3m, assuming everything can be built at the cheapest price, and the design kept really simple. One of the bonust prizes would be required to make sure the venture is profitable.

The lander design could subsequently be used as a transport system, conveying commercial payloads to the Moon.

Feel free to pick holes in this.

Google has left the door open for additional sponsors and I see no reason why a team couldn't solicit sponsorship money to supplement their program.

Is this an American only prize?

If not, funds could be raised using national pride for overseas efforts. A South Asian cell phone company for example (or Japanese company) could easily justify a $5 million or $10 million sponsorship of an Indian or Japanese or South Korean effort to win the prize. Cobble a few of those together and add in the prize money and your budget gets much bigger, fast.

With beamed propulsion being a relatively new technological development that could use a lot more development, I'd like to see a prize which would award the first team to lift a small payload into suborbital space using a ground-based power plant.  I'd like to see technology such these developed:

This really is very good news. With Richard Branson and Virgin Galactic already going ahead with the Spaceport in New Mexico, partly helped by X-Prize. Now NASA are running "You could work on the Moon" adverts. The UK has just announced via a working group that British astronauts will be funded. I wonder if the X-Prize  / Google announcement was timed to go along with the recent release of Google Sky ?

Extraordinary times. My current Heinlein reading "The Moon Is A Harsh Mistress" goes along very well with this !

True, I should have said "the group has recommended that funding be made available", but it looks like the ball is rolling now. I have already found out via the BNSC that a long term policy on no British astronauts (since the Apollo days apparently) has been overturned. That has got to be a major shift. Discussion here.

This is very reminiscent of the original X Prize announcement, with some people claiming that no one could win the prize, and others claiming that lots of teams would be in position to win.  My personal feeling is that at least one team will at least come close to winning, and if they do win those that claim now that its impossible will transmogrify their opinion to "so, they landed a rover on the Moon, anyone could do that".

See, that's what I have an issue with.  You say above you are not a person that is negative about it but by this statement here you are saying essentially "why bother"

History has proven time and time again that people who say this are consistently wrong.

As for the rest, $12 million is a lot of money for really making a "system of sytems", none of which require radical technolicigal deevelopment.  The "shift" and frankly the more important and overiding goal of this competition which I think everyone is missing, is not if a private company can do it but if a private company can do it at relatively low cost.  That in my opinion will be the real benefit of this prize.  If that can happen, which I think it can, will open up the frontier to other companies as well as force government to accept it can truely do a lot more for the same amount of money.

There is a big difference between the first X-prize and this Moon X-prize. There is a sizeable sub-orbital tourist market for the ones that can get there first, and the X-prize was a great way of getting a head start. Now with this moon prize, there is less of well defined market at the end of the development process.

This is quite important, winning the sub-orbital X-prize can be seen as an investment in getting into the sub-orbital tourist market. The Moon Xprize doesn't feature such a market, it will thus be harder to get investors on board, at least ones with the intention to make a profit

The launch of Dnepr is definetely more costly than 13 million USD - especially with current exchange rates. But you forget that you don't need to have a dedicated launcher for your payload, you could ride as a secondary payload on a couple of rockets including Rockot, Dnepr, Soyuz etc. It depends on the LEO mass of your payload on how much you would need to pay. For instance, if you can get your payload (rover, avionics, transmitter for base station, descent stage, EDS stage) to be under 500 kg, you will find launch opportunities that cost you between 5-8 million USD (depending on the primary payloads, exchange rates and timing).

P.S. this XPrize is geared towards university teams, no private company will touch it (no money to be made). You can build a complete package for a rather small sum, test it etc. by using commercially available components. Other rovers like Pathfinder do not compare well with what teams for this XPrize will come up - they use custom made components, have high standards for reliability, require the use and functioning of scientific instruments and extensive testing + a profit for the company that actually built the rover.

1. The strategy to win this XPrize is to build a minimum weight package in order to cut costs. The winning team might put an actual payload (rover and base station) on the lunar surface with less than 30 kg. And the launch of this mission would still cost several million USDs. With 30kg increments, it would be rather problematic to build a lunar base.

2. People might pay to drive a river on the lunar surface. The problem is, it's real tricky to get your rover hibernating through the lunar night. So the "common" small and simple rover will probably not live longer than 14 days. Even if you charge 50 dollars for 5 minutes driving, you will earn less than 200,000 USD in that period (assuming there are no gaps between the 5 minute drives). In order to recoup a 20 million investment, you would need 400,000 people to be willing to come up with 50 USD each for 5 minute drives and a rover that is able to survive approximately 4-5 years on the lunar surface...

In this case, yes. There isn't enough money, not enough time, not enough reason.

I was all for the CATS prize, X-Prize, elevator contest,  regolith challange, LLC etc, just not this one. I think X-Prize foundation would have helped themselves out much better by aligning with the V-Prize.

At first I was disappointed with the announcement.  But then I thought about the fact that there are no humans needed to fly here and so far I haven't seen anything saying that the rover needs to be minimum size.

I would approach it as a secondary payload to minimize launch costs and make the rover as small as possible and still make the 500 meters in one lunar daylight period.  (its hard to imagine a solar power vehicle surviving a cold lunar night but perhaps its possible, I don't know if anyone has tested it, but maybe thats on technology that would be found)

Navigating and Landing the payload softly is the hardest part in this challenge and its pretty hard.  

I think there will be several teams in position to win this prize and perhaps the bonus money.  Universities world wide could form groups with lots of students doing grunt work and programming, using Masters and PHD students to do some heavy lifting.   Many  schools will want to wave the flag of winning the Google X-Prize.

I can also easily see SpaceX just throwing money and a launch vehicle at it and not to make the money.  

SpaceDev maybe but being publicly traded would make it tougher.

Then there is the billionaire benefactor that just does it for kicks.

Also, I think a group like a low cost group of Indian engineers could be a series threat.

This one is going to be fun.  In many ways its harder than the first X-Prize and in some ways easier.

And yes a non goverment funded lunar rover will be a big deal and will spur development, no question.

{snip}

And nearly size independent.

a) Lunar X prize
Say 444 kg in LEO landing 300 kg on Moon.  This mass includes the lander.

b) Use a larger rocket and scale up the Lunar Lander.
4444 kg in LEO landing 3000 kg on Moon.  Say half to be the final payload.

c) Use an EELV
25mT in LEO landing 17mT on Moon.


Someone may wish to have a 1.5 tonne explorer running around the Moon.  There are lots of minerals to find.

When 8mT of cargo can be delivered ask about transporting parts of the Lunar Base.  A commercial company may be interested in delivering mining and refining equipment to the Moon.  The mining company can then try selling construction materials such as aluminium bars to the owner of the Moon Base.

This X Prize will have taught lowish cost transfer, so say $400 million to deliver 17 / 2 mT = 8.5mT
$400,000,000 / 8,000 kg = $50,000/kg on the Moon.  ($22,700/lb)

Agreed. I think this prize is nearly exclusivity geared at universities, no private company has funds to waste for a prize that could be very easily won by someone else before them  - so the risk is not worth the investment. University groups on the other hand can of course work on this task and build hardware on basically non-existing budgets - the hard part is to get someone to pay them a couple of millions for launching their project.

As mentioned above, professionals will not bother working on this Prize. They would have burned through the potential Prize money in the development phase already (40-50 engineers working on a proposal for 12 months using the facilities of the relevant company (for instance SpaceX) would come to a prize tag of up to 10 million USD).

Unfortunately, for such LEO mass/payload efficiencies you need a propulsion system with an ISP of more than 2000. So you would need to wait for a high thrust implementation of concepts such as VASIMR...

To give you some references on large payloads on their LEO mass/payload to the moon efficiencies - EADS calculated a 1:9 ratio for Ariane 5 ECA (23 tons into LEO; 10 tons into GTO; 2.6 tons of effective cargo on the lunar surface.

A smaller robotic mission put together on a shoestring budget cannot aim of course to the performance of an Ariane 5. I have calculated one scenario above, that yielded a mass/payload ratio of about 1:20. Your 444 kg LEO mass would give you an effective payload mass of approximately 20-25 kg on the lunar surface (still enough for a transmitter on the base and a small rover)

Thank you to the X-prize foundation!!  This is very exciting.  What a great way to boost excitement among the next generation of engineers and entrepreneurs (assuming university entrants)!  For smaller companies and even the larger launch companies this is a great way to improve name recognition among the general public.  I for one truly wish everyone competing a lot of luck.  Question, who are the likely competitors?

The serious contenders will be primarily teams from different universities. I doubt very, very much that any private company that we already know of (Surrey Satellites TEchnology Ltd., SpaceHab, etc.) would commit money to such a mission that has a high risk to not yield any return.

I agree that established companies probably won't put themselves in the 'prime' position.  But they might help with components like motors for the wheels.

Seems that the consensus is toward university teams.  I wonder if john Hopkins gets into this?  

I'll bet that this weekend the guys that are going to win this are sitting in a lab doing their preliminary design.

On the otherhand, Universities and Space companies are often very well connected. For example Surrey Satellites is owned for 85% by the University of Surrey (spaceX holds 5%). So maybe we'll see some Joint Venture between universities and companies. I also would like to see a comeback of TransOrbital :)

Opps I rounded the wrong way.  It should have been 280 kg on Moon.

The basis of these estimates was the SMART-1 mini spacecraft that was crashed into the Moon in September 2006.  The launch mass was 367 kg, propellant 82 kg and 287 kg (633 lb) was non-propellant (their rounding errors).
http://en.wikipedia.org/wiki/Smart-1

For my calculations I was using an ISP of 1530 seconds, a Delta_V of 5.93 km/s and an initial LEO mass of 443 kg.
Total Delta_V = Delta_V (LEO to EML-2) + Delta_V(EML-2 to lunar surface) = 3.43 + 2.52 km/s
http://en.wikipedia.org/wiki/Delta-v_budget

The figures were for a Busek BHT-600 Hall Effect thruster.  ISP 1530, 600 W 300A, flow 2.6 mg/sec
Efficiency 49.0% and thrust 39.1 mN
(I notice that large versions go up to 72% efficiency.)
http://www.busek.com/halleffect.html

Using m1 = m0 exp( -Delta_V / (Isp * g)) = 443 * exp( -5.93 / (1530 * 0.00981)) = 289.4 kg

There are other manufactures with rival ion thrusters.

How you actually land with an ion thruster I do not know.

Quote
To give you some references on large payloads on their LEO mass/payload to the moon efficiencies - EADS calculated a 1:9 ratio for Ariane 5 ECA (23 tons into LEO; 10 tons into GTO; 2.6 tons of effective cargo on the lunar surface.

They are using a chemical rocket to go from LEO to GTO, a lot quicker but less payload.

Quote
A smaller robotic mission put together on a shoestring budget cannot aim of course to the performance of an Ariane 5. I have calculated one scenario above, that yielded a mass/payload ratio of about 1:20. Your 444 kg LEO mass would give you an effective payload mass of approximately 20-25 kg on the lunar surface (still enough for a transmitter on the base and a small rover)

The spacecraft and base use a transmitter.  The thruster and rover use solar panels.  There may be a way of reusing.

It's simple... very hard, in small pieces, over a wide area, just like Smart-1. There is no electric propulsion with a T/W anywhere close to being able soft land on the moon. Not by many orders of magnitude. Landing will have to be chemical, almost certainly low ISP storeable propellants.

Some sort of electric propulsion may be attractive for getting from LEO to the moon, provided you can afford it, and provided you can survive many repeated passes through the Van Allen belts. You also have to carry around a hefty power system, which also has to be radiation tolerant, and all your hardware has to have a much in-space endurance.

Overall, I tend to agree with the people who have said this prize is less compelling than the original x-prize. Even if someone can pull it off and come close to breaking even on the prize money, it's hard to see anyone gambling that much on it. Unlike the original x-prize, there isn't a clear follow-up market.

I do think some of the smallsat folks (MOST comes to mind) might have a decent chance of pulling it off with that kind of money, but I don't see them getting the cash up front to try, and it would be very hard to break even.

I do like the way they have structured the prize, and it certainly would be cool if someone pulls it off.

Opps I rounded the wrong way.  It should have been 280 kg on Moon.

The basis of these estimates was the SMART-1 mini spacecraft that was crashed into the Moon in September 2006.  The launch mass was 367 kg, propellant 82 kg and 287 kg (633 lb) was non-propellant (their rounding errors).
http://en.wikipedia.org/wiki/Smart-1

For my calculations I was using an ISP of 1530 seconds, a Delta_V of 5.93 km/s and an initial LEO mass of 443 kg.
Total Delta_V = Delta_V (LEO to EML-2) + Delta_V(EML-2 to lunar surface) = 3.43 + 2.52 km/s
http://en.wikipedia.org/wiki/Delta-v_budget

1. SMART-1 did not use its ion thruster to go from LEO to LLO, rather it was injected to GTO. It used its ion-thruster from there to get to LLO and then for station keeping there. But as mentioned above, a ion-thruster is a non-starter when you want to get to lunar surface + in the price and size area for the mission we are talking about anything other than chemical is out of the question.

2. 5.93 km/s is the theoretical minimum delta-v required from LEO to lunar surface. Add 10% margins, course corrections and the fact that you might want to land somewhere else on the lunar surface than on the equator, landing maneuvers etc. you should assume more like 7 km/s as the total delta-v required. And as mentioned and outlined above, with chemical rockets a 400-500 kg payload will not get anything more than about 20-25kg effective payload on the lunar surface.

MOST was really cheap to build, it is cheap to operate and also cheap to launch. However it should be noted that it is very likely in another mass category than what a team that wants to win the Lunar XPrize requires - that is 52 kg... I think a good comparable payload would be AGILE or Monitor-E which was on the same Rockot that MOST was launched on, etc.

In any event, I still feel the biggest question is how small the rover and the base station hardware required beside the rover really can be made. Maybe we will be pleasantly surprised by a team presenting a viable proposal for a microrover (under 1 kg) that still can meet XPrize requirements (video camera, roving over 500m etc.).

Agreed, this variable determines the rest of the parameters like lander size, propellant needed, launch vehicle size.  Secondary payload will be the way to go but I don't know the upper mass limit on a secondary payload for commercial launchers.

I disagree that there isn't an obvious market follow on from this.  Keep in mind that space tourism was an unknown and caused many to roll their eyes when the first X-Prize was announced.  If someone can deliver a functional rover to the moon for 20 million (or so) and return HD level video and images it will certainly the mind set that a half billion is required to build a rover.

Also, this is Google sponsoring the competition.  Between their web portal and Google Earth I think the exposure of the teams and winners will be unlike anything the space community has ever seen.

Agreed, I wonder what is the price of a secondary payload launch. DeltaV from GTO to the moon shall be around 4 km/s, using storable propellant might be possible so.

Interesting discussion.

I was just reading the excellent speech by John Marburger  ( Director, Office of Science and Technology Policy Executive Office of the President ), which very clearly puts across important information about the context of the Google Lunar X Prize.

I had not realised the enormity of what is happening ...

"FOR EARTH:

Supply clean baseload power to the earth (and enable clean transportation fuel using off-peak power.) Direct implications include:

•    Energy independence from petrochemicals.

•    Large scale reduction of carbon inputs into the biosphere.

• Increased wealth and security with resulting decrease in rate of population expansion as per capita energy use increases in the developing world….without threatening the biosphere." (from the speech)

I'm already scrabbling towards half forgotten rocket engine manufacturer info in my archive. I'm also thinking of how the Orbiter Simulator could be used to test various ideas. It is not recommended to use it to test the actual mission, but it could be used to rule out unrealistic ideas.

I also found  that I did'nt know about. A supporting statement by Arthur C Clarke.

This is just wonderful. If the commercial viability can be proved, then will we see the oil magnates shifting their huge resources and finances into space futures ? From a resource that already has a time limit on it ? Will we see the the same forces that build oil tankers, one day building transportation as big to move resources from the Moon ?

GTO payloads are less than half LEO payloads so a commercial tramp shipper will think very carefully before launching to GTO.  Many bulk cargoes are happy in the Van Allen Belts - water, propellent, plastics for construction and powered down electric motors for instance.

The electronics in the rover will not like the radiation, so GTO is better for this competition.  As for chemical vs ion thrusters that is a mass and time trade off.  Does the GTO to LLO fuel weigh more than the Hall Thruster?

Using satellites to beam solar power to the Earth is almost certainly uneconomic, the Moon is further way making it even worse.

That part is pretty much a non-issue, as electronics in any spacecraft, including Shuttle and ISS, are vulnerable to at least high-energy cosmic ray hits. And since it's such an important known issue, it's incumbent on both the electrical and cpu designers/programmers to allow for that and mitigate it with built in recoveries when necessary (or at least a safe-mode implementation with alarms to allow mission controllers to diagnose and recover from it whenever it happens during the mission).

There is no 'almost' about it.  Space based power, although technically possible is a very long distant dream, at a minimum I would guess 100 years.  Photovoltaics on Earth are more than twice as expensive as grid connected power.  So photovoltaics in orbit or on the moon are going to be on the orders of 100's of times more expensive than anything you could do on earth.  Even if you had a functioning space elevator that could deliver cargo to Geosync for a few dollars a pound the photovoltaics for decades to come will be too expensive.

However, if there was a fully automated lunar factory that could shoot out PV cells and assemble them and you could produce tens of thousands of megawatts of PV cells and the whole system was very non-human intensive.  Perhaps.  But all can probably agree thats a long way off.

Even if all the obvious things could be over come who knows what environmental damage might be done by having a multi gigawatt microwave beam(s) going through our atmosphere would do, other than slowly cook birds.

Now if some point in the future we can produce large amounts of power in space, why not beam it to spacecraft, such as a human craft on the way to mars.  Minimal reactor and solar panels needed.  That would be a weight saver.

Is Google putting up the whole $30 million or are they buying an insurance policy like the X prize?  What other space prizes would people like to see if $30-50 million was the prize?  Do we think that a group will actually inverst the time and money and win the prize?  Does anyone know if Google will setup a site where we can see what groups have been formed so people could contribute if they wanted?

I believe there are already some long thread on SPS (space solar power) so perhaps that doesn't need to be in this thread. It's not closely related to the Lunar X-Prize.

John Marburger's speach also doesn't seem to have much connection, as no one has really explained how the Lunar X-Prize furthers those goals.

Back on topic, the guidelines  say
Quote
... soft land a craft on the Moon that roams for at least 500 meters ...
This seems to imply that it doesn't have to be a rover in the traditional sense. A hopper might be a more viable approach, as very small rovers mobility can suffer.

So the Virgin Galactic Spaceport in Nevada has no connection with the previous X Prize ? A whole history of innovation in technology over the last 200 years has no connection with solving problems and meeting challenges ? I quote from the recently signed Global Exploration Strategy that addresses similar concerns ...

"Theme 1: New Knowledge in Science and Technology

At its core, exploration is about taking manageable risks to discover what is unknown. Significantly, much of what it reveals is unknowable in advance. This presents challenges for those wanting to weigh the risks against the returns from new investments.

This problem is as old as innovation itself; when Heinrich Hertz developed the first apparatus to transmit and receive electromagnetic waves in 1887, he hardly envisaged the vast global telecommunications networks of today, or the economic activity they sustain."
(page 7-8)

In effect your kind of statement asks us to prove a negative. To predict how the Google Lunar X Prize will meet the goals that Marburger discusses, is demanding the answers to questions that have not yet been answered. A sort of Chicken and the Egg Problem. The whole point of this kind of enterprize is to stimulate the kind of activity that we need, that will score the goals that can solve the problems of our age. Energy, environment, population.

This is an apples to oranges comparison.

The previous x-prize was quite different. Anyone building a winning craft had the potential to tap into several pretty plausible markets. It acted to stimulate development of the suborbital tourist market. Recouping some of the investment with the prize was sufficient to get someone to do it (remember, the winning teams backers spent far more than the prize amount.)

It's not at all clear that the lunar prize has a similar effect for any plausible market. If someone spends 50 million winning the lunar x-prize (a similar factor over the prize value to what was reportedly spent on the winning original x-prize entry), I don't see how the state of the art will be advanced, or new markets opened.

If someone spends less than the prize amount and wins the prize, that would be impressive, and probably have a modest impact on low cost planetary exploration, but the relationship to the big picture goals you describe seems pretty marginal.

If you could repeatedly send minimal rover to the moon for a cost of 19 million, it's not at all clear that you could sell many of them.

Perhaps I just lack the vision see it.

Once the method is known for 10 times the price you can send a rover 10 times, possibly 100 times, larger.  A rover that big can explore for useful minerals on the Moon.  NASA would charge say Lunar Mining Unlimited a lot more than $330 million to send a survey rover to the Moon.  The Lunar Landers in this years X Prize could be used to return the mined minerals.

I predict this is one X-price that wont be claimed.

Also, i saw the video they created for the X-price announcement. I doubt the whole world will be standing around tv screens in suspense over a rover. Without the human element, it wont be as exiting. Lets face it, without manned flight, NASA wouldnt even have half the budget it now has to send unmanned vehicles to Mars and other places. Lets face it, without half of these vehicles having some PR lines attached to it like ---"exploring to lay the ground for future human missions, or "search for life", there would be no interest in them.

duh, with realistic propulsion performance, Falcon 1 or other launcher that can throw roughly 500kg to LEO, you can land 30KG of a payload on surface.
Thats more than PLENTY for modern robotics, given that the thing does not have to be packed with science instruments at all.
I also think that using a single set of engines from LEO all the way to lunar surface, with drop tanks makes loads of sense.
There was a lunar IceBreaker design, led by CMU and Red Whittaker sometime in 2001, that had thrusters integrated directly into rover body, to simplify things.
By the way, the same mr. Whittaker, "THE robot guy" has announced his intention to participate already.

As to anyone saying that there is no business or markets on the moon, thats just incredibly short sighted. Any of the organizations involved in the Eighth Continent project ( http://www.isruinfo.com/ ) would jump at the chance of landing their experiments with proven platform at low cost on lunar surface.

Another thing. There should be no trouble finding sponsors for this competition.
Every company trying to bring robotics to consumer marketplace should welcome the chance to get their logo and technology on the lander. Honda, Sony , US based iRobot, heck, even Microsoft has pitched robotics recently as their Next Big Thing.
Honda has spent north of hundred million developing ASIMO, and so far all they have gotten out of it is PR. Putting a few tens of millions behind this, and providing technology bits should be a comparatively good investment for them and the like.
TransOrbital ( http://www.transorbital.net ) was shooting for becoming the first privately funded mission to moon, and even with their obscurity and low publicity they secured sponsorship from HP. With publicity around google and everything they do, getting sponsorship from tech giants should be  way easier.

There arent just enough interested multimillionares to go around to mount a manned lunar tourism operations, and just about everything else can be done far more effectively with teleoperated robots. Given current launch costs, that is.

There are common factors that inspire innovation, too numerous to list here, and easier to understand if you have first hand knowledge, or have at least engaged with the spirit of the endeavour.

In fact, look at Wikipedia. An idea that seemed ridiculous not so long ago. Mass editing of a single article ... chaos ! Of course now we know.

I was watching a video  of  Sergey Brin , one of the founders of Google. This guy followed up an idea in his college days that was regarded as "impossible", a comprehensive algorithm that could actually index the internet properly. He "dropped out" and their idea worked ! He is now worth 16.6 billion dollars. In the talk that was recorded in 2005, the Google relationship with NASA comes up (I remember hearing about this in 2005). Brin perks up, and says "maybe we'll build space tethers later on, but we're just more interested in some office space at the moment.." :bleh:

thinking about the problem a bit, i think it would be doable within $20M budget if all and any feature creep can be avoided.
No science payloads at all. Just the equipment to fulfill competition rules ( wheels, cameras and antennae are pretty much the only requirement ).
Perhaps no solar arrays at all. to fulfill the 500m driving distance, a set of batteries could be enough. You can get up to 350Wh/Kg from non-rechargeable batteries, and up to 200 from rechargeables. Maybe just have thin-film solar cells on the body of the thing, to prolong the battery life a bit.

savuporo, I think solar cells are essential, who knows what driving problems and how many rocks need to be avoided or slopes climbed.   I would shift more emphasis on solar cells and less on batteries.  Because even if you try to survive a lunar night you won't be able to keep anything alive through those 2 weeks (assuming non-polar landing.)  

Perhaps you can run a hybrid system.  Charge a battery or capacitor with the cells and take a burst of movement then wait to recharge.  If you assume a landing that gives 10 days of drivable conditions you need to average 2 meters per hour, so at about 1400 Watts per Meter squared then you can assume a solar cell efficiency, then assume a mass of your rover, energy needed to move 2 meters per hour, size your solar power (lots of factors in there to evaluate, angle, exposure etc.) and you have a good base to start with.

Light rover with lots of solar cell surface area is a good place to start.  

I think one of the most interesting parts of the Prize is trying to wake up and function after a lunar night.  That will  require a robust design.  If possible that opens up some very interesting possibilities as to range and probably the only way to meet the 5000 meter bonus.

Edit: And the flattest's smooth place to land and sprint for the hills before sunset.

Why stick with a $20 million budget?

According to the Business Week / Interbrand 2007 report, in the last year Google increased its total brand valuation by more than any other global company. Google is hot and getting consumers to subconsciously or emotionally link a company's brand identity with Google would be a big win for the marketing and PR department of that company.

Therefore, all contestants should immediately start seeking sponsors who desire to associate their brand with Google. A contestant can sell BOTH participation in a lunar rover mission and the opportunity to associate a sponsors corporate identity with the Google corporate identity.

For example. Suppose Aardvark Aerospace lines up XYZ Technology Corp as a sponsor.

XYZ can advertise that they are a proud contributor to the Google X Prize Moon 2.0 challenge and thereby link XYZ with Google in the minds of consumers.

Wash, rinse and repeat and a savvy team of salespeople might well raise well over $20 million from ancillary sponsors without needing to take the prize money into account at all.

surviving the lunar night is not the core prize requirement, thats a bonus.
thats where the feature creep starts too. Designing the rover to survive few days in cruise phase and couple hours on surface is far easier than designing it to survive lunar night.
easier = cheaper

By the way, here is an early paper on existing rover design, led by the very same Red Whittaker

You keep posting generalities that have nothing to do with the specifics of the lunar x prize. There's no doubt that throwing a 30 million prize at a plausibly achievable technical goal will result in SOME work in that area (as would simply handing the cash to a university as grant in that area), but as I understand it, the X-Prizes aim for something bigger.

The 30 million google puts up is supposed to be a catalyst for much larger advances in that field. You can see clear examples of this in the original x-prize (and the Orteig Prize which inspired it). How specifically do you believe this this particular prize accomplishes that ?

tnphysics:
The suggestion of "scaling up" the results to support manned exploration is ludicrous. The key to winning this prize (barring some spectacular miracle) is going to be:
1) getting the cheapest possible ride to orbit. It's hard to get ANYTHING in orbit for much less than $20 million, so this is going to drive everything.
2) miniaturization (driven by the above)
3) using off the shelf components.
4) accepting high risk (because of 1 and 3)

1) means one of the following:
- a surplus Russian missile
- a cheap launcher from the a developing country (Indias PSLV is rumored to be available in the range of 10-15 million dollars),
- unproven and very small Falcon 1
- riding as a secondary payload.
None of these are applicable to manned flight, nor to advancing the state of the art.
2) means having the absolute minimum capability to meet the goals. It also isn't applicable to manned flight, unless you are proposing NASA only hire children or midgets ;)
3) isn't likely to be very applicable due to safety concerns.
4) is directly opposed to manned flight.

I meant the lander, not the rover.

What you said is true, except maybe for being risky (could add redundancy)

The suggestion of "scaling up" the results to support manned exploration is ludicrous.
While technically its ludicrous, what a lot of people seem to miss is a different type of scaling up: organizational.
Thats the same argument that is often made that suborbital launchers are no stepping stone to orbital ones.
Thats wrong, because it neglects organizational issues. You see, having an organization ( likely a company, maybe a nonprofit entity ) that has done successful manned suborbital launches, is far more likely to pull off successful orbital launches than the one that starts from zero. While the technology may not directly apply, experience base, contacts in industry and existing organizational structure all apply.
The same holds true for that lunar thing. The team that pulls this unmanned landing off, will have quite a lot of relevant experience in mounting a manned flight. They may not have the cash or all the technologies, but successful companies are known to attract investments ...
Building functional organizations is often more important than having the technology ( which can be acquired, licensed, bought ), for success.

Notice that NASA went through both of the exercises, suborbital flights and unmanned landings on moon before undertaking the next steps.

I have noticed that Spirit and Opportunity have attracted A LOT of public attention.  At present a smaller portion of the Lunar surface has been explored in detail than the Mars surface.  

No, that's not true. There were six manned lunar landings in Apollo, plus various Surveyor and Lunakhod rovers.

There have been five successful Mars landings (Viking 1, Viking 2, Pathfinder/Sojourner, Spirit and Opportunity.)

Apollos 15, 16, and 17 each covered more ground than Spirit and Opportunity have to date.


I may have overestimated the amount of ground covered by Spirit and Opportunity, but I have not  overestimated the amount of public interest they have attracted or the national prestige they have earned for their research accomplishments.  Very, very little of the surface of the Moon has been examined in detail.  A $20 to $30 Million investment to put a nation, and its research teams into this arena - with proven success for the transportation system and research platform to get the sensors into position - will be very attractive to the countries which have spent far larger amounts to be counted as partners in the ISS.  

This will be seen as a godsend for nations, and their high tech, national corporate sponsors, to secure a permanent place in the history of space, and lunar, exploration.

I just saw a talk by Peter Diamandis about the Lunar X-Prize.  It was an interesting pitch, and while I'm not sure how well it went over, there were some laughs and applause, even at the non-cheesy parts.

I asked him if there was the same ban on government funding that the Ansari X Prize had, and he said something about only being able to use technology that was available to all teams.  The natural follow-on question to that was "does this mean that if an Iranian team enters, that no one can use anything covered by ITAR?".  Didn't get a good response to that one, and it seems like it could be pretty important.  He did say that American teams would be at a disadvantage.

That said, I could see this advancing the state of the art in low-cost deep space navigation and attitude control and such.  Not sure that that's relevant to manned space flight, but it'd certainly be useful for unmanned stuff.

I need to think more about this.

This is certainly true, but IMO, a low budget micro-rover isn't significantly better at achieving this than developing any other spacecraft. Which is better for developing a lunar team, a manned sub-orbital craft or an unmanned rover ? Either one is a very small step toward the larger goal.

Again, I'm not saying the lunar x-prize is a bad, or that it will not produce anything of value. On the contrary, demonstrating low cost planetary exploration would be great. There's a pretty good chance that the winner would be able to sell science oriented follow-on missions, following the MOST philosophy of having one (or maybe a couple) relatively simple instrument that does one interesting thing well. For the price of a traditional planetary mission, you send a bunch of these to your target, which in some cases would be a better overall investment. It could even dovetail nicely into the VSE for pre-scouting landing or ISRU site.

What I'm skeptical of is the ability of this prize to attract funding for the competitors, and the extent of it's possible impact outside a very narrow slice of space science.

Thinking about this some more, one of the big issues that small launch vehicles run up against is a comparative lack of payloads.  And when small payloads exist, they usually cost enough money that saving a million bucks here or there on the launch vehicle isn't worth the added risk.  Developing reduced-cost payloads would be very useful to the small rocket guys.

I wish that the competition had been to Mars instead , as then we could use aerobraking instead of having to rely on rocket thrusters.
I guess an inflatable crash bag could do the trick if we can slow the spacecraft down with the ion drive enough.

Aerobraking buys you some reduction in propulsion system delta-V, while adding lots of complex systems to the craft ( heatshield, parachutes, and final landing method: either airbags or still retrorockets ) and also additional points of failure.
Its not clear-cut, for small payloads like these, that just adding more propellant wouldnt be simpler and cheaper in the whole picture.

Something just occured to me.
There should be some reasonable entry barrier for participating in competitions like these, to avoid completely bogus teams creating noise and riding the publicity, while in process maybe discrediting the entire thing.
There were some "participants" in the original X-Prize that were obviously just poor jokes, and there's at least one enlisted for LLC as well.

DARPA GC does this based on proposal evaluation and in qualification runs, before the actual event. I this case, maybe submitting a general parametric overview of the approach taken, with launch vehicle selection, mass budgets, and so on, so they could be run through basic sanity check filter.

Thats not to discourage nontraditional approaches, like using specifically developed launchers or something, but at least the model would have to be physically feasible, and detailed enough to produce virtual models that can run through simulators and animations of the approach taken.
In other words, interesting website and PR material for Google to use.

Im actually very supportive of the prize, i'd be glad to be part of any teams myself ( anyone needs a embedded developer, with lotsa robotics and control systems background ? ;) )

When i said "PR material for google", i meant it as a good, useful PR material ( since when did any mention of PR begin meaning "shooting it down?" )

Google is a internet company, they should know how to present stuff on the net to attract lots of public interest, there are plenty of opportunities here. However, you need to have some good core material to keep people interested and coming back to your site. Having rough plans from teams competing, publishing progress news once in a while, the works.

Lunar Lander Challenge website for example got off to a good start ( http://space.xprize.org/lunar-lander-challenge/ )  with the Participant overview, "Team Matchup page" and so on. However, it hasnt been updated much and isnt very well publicised, people dont stumble on it often. There is no comments section, no updates from teams ( or at least aggregated newsfeed from team blogs or something )

Google definitely has resources to pull something better off. Provided, that the core material to work with is actually worth something .. which brings me back to my original point.

There should be some entry barriers for the teams, to keep clowns and just viewgraph sketchers out.

I guess an inflatable crash bag could do the trick if we can slow the spacecraft down with the ion drive enough.

Seriously look at the plans for ranger 3 and 5. The plan was to hard land a seismometer on the moon wrapped in a balsa wood shell with a solid retro rocket. And this was in the 60's. Obviously the closing speed is low enough that a lander equiped with a simple retro and a balsa wood shell or air bags could surive. If you use Ion power to go from earth orbit to lunar impact a fairly large rover with a solid retro can be launched on a pegasus or falcon I or a GTO hitch hiker or ... You just have to budget large solar panels, the ion engine, the rover and the  retro.

There is an excellent pdf on the history of ranger, only 471 pages ;-)

That would certainly reduce the odds of google having to pay out. Mars is FAR harder than the moon, for many reasons.

For all practical purposes, using any current ion drive would be the same as not slowing down at all. For example, the PPS-1350 hall thruster on smart-1 is rated at 88 milli-newtons of thrust, and has a mass of 5.3 kg It's not entirely clear what that mass includes, but certainly not 1.5KW worth of solar panels.

Needless to say, this kind of thrust/mass ratio cannot prevent a multi km/s impact on the moon, from which "crash bags" will offer little comfort.

A solid retro as kevin-rf suggests is an entirely different proposition. It can relatively easily soak up the required dV, although I suspect mass constraints will argue for a softer landing and a higher ISP rocket. A minimum mass rover is going to be more delicate than a simple seismometer.

to fit on Falcon-class payloads ( ~700kg ), you realistically have to have above 350 ISP for the entire LEO to lunar surface leg.
Probably single gimballed engine or single set of differentially throttled engines, dropping tanks may or may not help the payload mass fraction,
Big single set of tanks: better volume to surface area ratio, multiple sets of drop tanks : less weight for next burns, but added complexity and weight of dropping systems, plus poorer volume to surface area.
Lox/Methane or Lox/Propane could fit the bill.

I thought you were being facetious. In the UK any mention of PR, or "Spin" is usually a chance to have a gripe at the system and the money bags. So, yes, nothing wrong with Google generating a bit of publicity ... the whole point of this commercial space enterprize anyway, is exactly that, to be commercial !

I'll have a closer look at the site. That's a good point. As a net enthusiast myself I know what you mean. It's at it's best when there are up to date continuous reports. When a remote interested party actually feels like they are being bought into the buzz of the whole thing. Maybe something like NASA TV's "The Edge" program would do the trick. Where we have the "expert" and the "newbie" interviewing various people in a humorous way. That could be published on Google Video. I wonder if it would stretch to a full time streaming TV channel ?

I have aspirations of joining a team, but I don't have engineering or development skills. I do have lots of multimedia and artistic skills though... hmmmmmmm.

I have some questions on how to get there.
Like how hard is it to build an upperstage to launch your rover to the moon, to get into lunar orbit and then land?
And for piggyback riding, could this student made upperstage be dangerous for other satellites onboard?
And how about communications? How big does your antenna need to be to receive HD television?
And for the bonus prizes, water ice only appears at the poles, how much extra fuel would it take to land there?
Because finding water ice would be very important for a moonbase in the future, and while being on a lunar pole it could be "easy" to ride to the far side of the moon (automatically of course) to keep it exposed to sunlight.

MEDIA ADVISORY: 07-145

NASA OFFERS $2 MILLION LUNAR LANDER COMPETITION PRIZE

WASHINGTON - During the X PRIZE Cup Oct. 27-28, NASA's Centennial
Challenges Program will offer prizes totaling $2 million if competing
teams successfully meet the requirements of the Northrop Grumman
Lunar Lander Challenge. The challenge will take place at Holloman Air
Force Base, in Alamogordo, N.M.

The purpose of the lunar lander challenge is to accelerate technology
development leading to a commercial vehicle that could one day be
capable of ferrying cargo or humans back and forth between lunar
orbit and the moon's surface.

To win the prize, teams must demonstrate a rocket-propelled vehicle
and payload that takes off vertically, climbs to a defined altitude,
flies for a pre-determined amount of time, and then land vertically
on a target that is a fixed distance from the launch pad. After
landing, the vehicle must take off again within a predetermined time,
fly for a certain amount of time and then land back on its original
launch pad. There are two levels of difficulty, with awards for first
and second place at each level.

With most of these types of competitions, around 50% seem to be complete jokers, the rest of them have semi-credible ideas but mostly too ambitious, which usually leaves you with two or three contenders that could pull it off. Thats if the stars, but mostly funding, align right.

Of the current lineup, Odyssey moon and Astrobotic, perhaps also Selenokhod seem almost credible.
Any one that talks about developing their own launchers can be counted out.

Things take time, much longer than you think it will at first. Rutan's bird is just now getting ready to send people (and even then, it will take a while until paying folk go... I'm sure a good year after first breaking the Karman line in SpaceShipTwo), SpaceX took longer to get payloads to the Space Station than first expected, and there are several other examples.

Should we throw up our hands and give up? Does this mean it's all fake? Nope and nope.

Astrobotic is now a company with several employees. Some of the other groups are also still going.

It's taking longer than original projected, but that doesn't mean it's some kind of fake.

In fact, I'm impressed at how long many of these newspace companies have held on, in spite of it taking a long time. Lots of them are still around and making significant, if slow, progress. If even a handful of them ultimately succeed and at a slower rate than they projected, it will be a good thing.

The schedule is naive, and the budget as well, but remember that the prize money is only one part of the budget!!! That was true for SpaceShipOne like it will be for the lunar X-prize.

 One of the teams, as far as I can tell the one furthest ahead in terms of actually being able to launch something ('Barcelona moon team') has managed to book a Long March 2C. They've not clarified exactly how they got the funds to do so, but the suppliers of LM (China great wall industry corp.) are listed as an actual sponsor, so I'm assuming they got at least some kind of discount. They also mention CGWIC are producing their propulsion module for the landing.

Prize money in such competitions is never meant to cover the entire budget, but instead give a generous financial boost. Participants have to find other, preferably sustainable, funding to achieve the competition objectives.

What's the going rate for Strela? Wiki listed $5M, astronautix $10.5M

1.7t to LEO, own TLI kick stage required.

Development of such a TLI stage is a non-trivial effort.

This is a purely subjective observation, but I do not believe that NPO Mash will ever sell a Strela, for certain internal purposes.

No doubt, but ought not to be insurmountable for teams developing lunar landers.

Rokot then? More expensive but the 3rd stage should be able to provide at least part of the TLI burn.

We are in the theoretical aspect here. The Rokot third stage might provide some of that TLI burn, but all that means is that the prize contender has to design and build some fraction of a TLI stage, which basically means smaller prop tanks. In either case, the prize effort would transmogrify into a rocket development effort, which the teams are not equipped for.

I should also mention that Rokot only flies from Plesetsk, which is no fun for a lunar mission.

Nope.

Google's contribution is the prize money. There is no ethical way that Google could fund any portion of a team's budget before the prize is won.

Prize money in such competitions is never meant to cover the entire budget, but instead give a generous financial boost. Participants have to find other, preferably sustainable, funding to achieve the competition objectives.

The reason why this is often true is that there are often secondary benefits to winning the prize; ether secondary cash flows from the prize winning effort, or, in the specific case of the Paul Allen SpaceShip One effort, technology results that could be used for commercial ventures.

The lack of an actual lunar mission is telling us that there are no secondary benefits from the prize defined mission, at least none that are obvious now.

The other possible data point is that it may be the case that Falcon 1(E) is not flying because no Lunar XPrize team actually was ready to sign a contract for a mission with SpaceX for this launcher.

There are a million ways to structure prizes.  You are free to start up a thread about optimal prize structures.

However, the issue in this thread is that there is an existing prize with existing rules, which cannot be changed. So, under the existing rules and the existing reality, it would appear that no one is building a TLI stage, and virtually no one has signed a launch contract.

Things take time, much longer than you think it will at first. Rutan's bird is just now getting ready to send people (and even then, it will take a while until paying folk go... I'm sure a good year after first breaking the Karman line in SpaceShipTwo), SpaceX took longer to get payloads to the Space Station than first expected, and there are several other examples.

Should we throw up our hands and give up? Does this mean it's all fake? Nope and nope.


It's taking longer than original projected, but that doesn't mean it's some kind of fake.

   First: My remark was directed at Mr. Allen, the sponsor of the prize money. It is he who is dangling a 'carrot' that is most likely out of reach
of all participants.

  Second: A Moon shot requires a booster of at least a million Newtons thrust, 1'st stage, for minimum payloads about the weight of a laptop; and that piece of launching hardware is NOT CHEAP.

  Third: If you plan to soft or hardland anything with electronics and supporting systems on the Moon, consider the Delta Vee to do it.
Roughly about negative 2500-2700 meters/second.
And with expensive hypergolic propellant at about 330 seconds of Isp,
the mass ratio is (off the top of my head) nearly 2.3.

So if any of the participants wants to send 230 kg to the Moon, make sure
130 kg of that is propellant.

Doable, I guess, if you have a few million dollars in your piggybank.

That's only a 32:1 ratio of fueled to empty weight; given Atlas had over 50:1-at least as far as I can tell-it seems reasonable enough.

But that's just the core stage, Moe's figures are for entire LV. Include the 0-booster stage in Atlas D and ratio drops to 21.5

Agree with you there. There's not really much point arguing about technical specs of a rocket when both it and any attempt to actually build it don't really exist.

Go read about the progress that the various teams are making. It's still likely that Moon Express will make the deadline, and maybe a few others too.

As for the prize money total, you *never* want to offer a prize so big that it attracts people who only want to win the prize and then go back to working on other things (or the next prize). What would be the point of that?

If no one gets the prize, but two or three exploration-oriented businesses (like Astrobotic, for instance) are spun off as a result, then the return-on-investment of the prize money (not counting overhead) is infinite.

Let me address some of these issues.

First off, if there has been significant progress towards winning the prize, that news should be posted here.

Secondly, I did not state that the prize money should be equal or greater than the cost of mounting a mission, but that rather, the lack of significant progress by the teams is telling us that there are no significant secondary profits or downrange profits from the prize effort.

The reason that teams try to win prizes that don't recapture their costs is largely due to the existence of secondary profit centers  (or donors)  or the possibility of future profit streams from winning the prize. In this case, these have not materialized.

BTW, there is talk that the prize rules may be changed. This could only happen if no one is close to actually launching.

From the ISRO general thread http://forum.nasaspaceflight.com/index.php?topic=32023.msg1161842#msg1161842
Quote
Team Indus also needs $34 million (about Rs 200 crore) to build and launch the spacecraft. Isro itself will charge about Rs 100 crore for the launch
If ~$17 million for PSLV is the actual market price, that's would make at least one option that cost less than the prize purse. I've seen that number quoted for PSLV-CA before, but I'm not sure how reliable it is. How much can CA send to to the moon?  Chandrayaan 1 was launched on XL and reportedly 1.38 tons, but a substantial amount of that was used for propulsion. A naive extrapolation would suggest CA could do ~800kg to the same initial orbit. http://nssdc.gsfc.nasa.gov/nmc/spacecraftDisplay.do?id=2008-052A says  Chandrayaan 1 dry mass was ~520kg. Taking the same ratio would give ~300kg (to lunar orbit, rather than direct landing).

From the same article: "We believe the US teams are spending some $80-90 million"
Somehow, I doubt any of the teams have that much to spend. They might need that much to actually fly.

Hmm, this was the most likely GLXP thread I found in search, but mods please move if there is a more current one.

So it's September 2014.  16 months left.  There isn't much indications that any of the teams have actually booked launches, in spite of some earlier claims.  Astrobotic claimed they had booked a Falcon 9, but they're not on SpaceX's manifest, which is pretty full through the end of next year.  Team Indus claimed to be launching on an Indian launcher, but there hasn't been anything recently to indicate that's actually going to happen.

I'd love to see someone win this prize, but sadly it's looking pretty unlikely.  Or is there reason for optimism that I'm missing?

Would another extension really help?  If none of the teams has yet been able to raise the money to buy a launch, why would they be expected to do so in 2 years, 5 years, or 10 years?

I do think there's a reasonably good chance SpaceX will be able to get rapid first stage reuse working and sell cheap launches on used first stages before the end of the decade.  They might also have a lot of spare capacity on Falcon Heavy flights for secondary payloads.  Either of those and an extension to the Lunar X Prize deadline might be the only realistic hope the prize will be won.

Astrobotic claimed the same thing about a flight of Falcon 9.  Then there was just silence and now they're not on the SpaceX manifest.

I think there's a difference between signing a deal for a launch and actually coming up with the money to pay for it later on when it becomes due.  Is there any indication that Barcelona Moon Team has come up with the money to keep their launch on track?  I haven't seen anything about a concrete launch date or position on the Chinese launch manifest.

This news posts shows they do have specific launch date arranged with CGWICG; beyond that there's a frustrating lack of specific information from either party. Their posts show that they've also ordered their lander's propulsion system from CGWIG, but none of them explicitly state if work has actually started on it or if it's part of the same contract. They haven't posted updates of any kind since february.

Yeah, that's what worries me, the recent silence.  It's possible things are going along smoothly behind the scenes, but that doesn't seem likely.  When teams are making progress, they usually like to make lots of announcements about it.  They have an interest it keeping up public excitement.

Secondaries don't appear on manifests.

The Rocket City Space Pioneers were planning to buy a launch and sell payload space, but I don't think they had enough takers, and then Moon Express acquired them.

Moon Express remains the favorite, I think. (Which shouldn't be a surprise, as it's run by SEDS alumni and everyone knows the X-Prize Foundation is just the Peter Diamandis' version of every Adam Sandler film.)

Primary comsat payloads have very specific flight profiles they like to take for thermal and other reasons.  It means they only have limited launch windows.  The people who own the primary payload aren't likely to let their bird wait on the ground or take a launch window they normally wouldn't just to get a favorable alignment with the moon.  So an eliptical GTO the secondary finds itself in isn't likely to be favorable for TLI.  And there's still a lot of delta-V to actually get to the moon, and then still more to soft land on the moon.  And the lander has to be able to drive itself a significant distance on the surface.  I'm not sure it would be small enough to be a viable secondary payload.

Also, a secondary with that much delta-V capability might be considered a risk to the primary if it misbehaves, leaks, etc.

I think it's not impossible it could go as a secondary, but there might be factors that make it impossible.  That's probably why there was talk of sharing a ride among several competitors -- easier to share a ride with something else going to the moon than with a comsat.

I am not yet convinced it is a bad idea. The delta-v from GTO to TLI is quite small, especially if it is a supersynchronous orbit. The moonbound vehicle can adjust the orbit so it aligns with a moon trajectory after a while and then injects to TLI. It only requires ability to wait maybe several weeks in that orbit waiting for alignment.

But I don't know, how heavy the vehicle would be. If it is the size of a Com Sat it won't get a cheap slot as a secondary.

German X Prize team announces launch contract

Quote
WASHINGTON — A German team competing for the Google Lunar X Prize said Nov. 29 that it has signed a contract to launch its lander, carrying two rovers, by late 2017.

Berlin-based PT Scientists said that it signed a contract with Spaceflight Industries for the launch of its lander as a secondary payload on a vehicle yet to be identified. Seattle-based Spaceflight serves as a broker for secondary payloads and works with a number of launch service providers.

Karsten Becker, head of electronics for PT Scientists, said at an online press briefing Nov. 29 that a SpaceX Falcon 9 is the most likely vehicle that Spaceflight will use to launch their lander. “We are very confident that it will be a Falcon 9, but we cannot say that it will be a Falcon 9 just yet, because Spaceflight needs to confirm it with their other customers, and SpaceX,” he said.

Google Lunar X Prize teams get extra time to win competition

Quote
WASHINGTON — After months of stating that it would offer no further extensions of the Google Lunar X Prize competition, the X Prize Foundation announced Aug. 16 it was effectively giving the five remaining teams a little extra time.

In a statement, the foundation, which administers the lunar landing competition, said that teams now had until March 31, 2018, to complete all the requirements of the prize, which include landing on the lunar surface, traveling at least 500 meters, and returning video and other data.

Good idea.  Make the competition a little easier - first rover to see its shadow, it wins the prize.
