I don't get the hype.First of all, most of the cost estimates here are absolutely ridiculous. Second, Red Dragon will test certain technologies for NASA and SpaceX, but it's still an order of magnitude smaller than what is needed for human missions.
Whether Red Dragon will be picked over other reentry concepts like MSL, InSight for science missions is also questionable.
So you can consider a platform for a Mars program out of it. Robert Zubrin's “Mars Semi-Direct” concept would make use of three Falcon Heavy launches every two years, as an example.
Neither of these comes from volume reused components like Dragon, which has flown more times.

But screaming "revolution!" every time SpaceX announces some new plans is ridiculous.
The Red Dragon have a payload capacity of 2 to 4 metric tons to Mars surface depending on orbital mechanics.
Even if the Red Dragon is triple the cost of the regular Dragon 2.That is still cheaper then the MSL platform that can lands only a few hundred kilograms of payload on Mars.
Since the Dragon is in mass production.
I'd say that a totally-privately created American launch vehicle and spacecraft, not led by JPL, which is sending a human-capable spacecraft to Mars is a pretty momentous deal.
Announce two years in advance, add more years of slippage, and anything seems ho hum. Things must seem a lot more revolutionary to people who aren't paying attention. There's people out there who hear about CRS-8 docking to the ISS and are like "OMG that's revolutionary!!" SpaceX should be commended for making their achievements seem routine.
If you can land a 6 ton lander on Mars surface. You probably can use the same lander design to deliver some kind of rover on Venus surface.

Can be done, but you're going to need either super simple high temperature electronics or really aggressive active cooling, dumping heat into a furnace. You'll need a very powerful RTG/ASRG for that....but it can be done.

Doesn't Russia make significant use of diamond-based electronics in its space program? Maybe that might be suitable for Venus, too.
The real question is whether other countries besides the U.S. will take advantage, and companies other than SpaceX?If they do then this capability will play a significant role in preparing humanity to expand out into space. If no one else takes advantage, then it just ends up being a revolutionary precursor to whatever comes next.I hope it's the former and not the later...

I'm sure it will be stripped of anything that makes it LEO human-capable.You're honestly trying a little too hard to see the negative aspects of this, which certainly exist but do not make it any less of a stunning accomplishment (if/when it occurs). As for your question about cost, MSL cost $2.5b (conservatively). It is a stunningly beautiful feat of engineering with finely-prepared instrumentation and an intensely complex and bespoke/tailor-made landing system that would be difficult and expensive to apply to anything other than Curiosity itself. My estimate for Red Dragon would probably max out at $300m. Actual costs for the spacecraft and launch vehicle are likely around $200m (no clue as to the actual cost of Dragon V2), and then add on approximately $100m for R&D/NASA collaboration. Literally an order of magnitude cheaper for 2x the payload with what is arguably an off-the-shelf solution (given Musk's very recent AMA on Twitter in which he explained that Dragon V2 was in part literally designed with the idea of propulsive landings on Mars in mind). It can't travel miles like Curiosity, but one can certainly imagine previously unconsidered options for local exploration around the landing site.

I don't think it'd be wise to guess too far ahead, after all we need to see if SpaceX proves itself. If Red Dragon lands, it will change the game for Mars just as it did for LEO. Boeing, Lockheed, and even JPL may want to step up their game.
Boeing and Lockheed probably need a change in approach, but they'll adapt, it's what they're good at. JPL probably needs its role redefined - it'd be good if one day JPL is only designing/defining payloads, not the lander/spacecraft/probe itself. None of that expertise and proud tradition of service needs go to waste, it'll just be refocused by the years.
All 3 in their own ways have been used to having "monopolies" in their fields. More universities beyond Caltech have gotten involved with probes since the 1990s, but they continue to have the loudest voice and biggest influence, yet even they can't figure a straightforward Mars sample return scheme. And neither Starliner or Orion have legs to land on. SpaceX is going to embarrass them all.
Stuff like this happening might drive a bubble in space investment (and there sort of is one already in the microlaunch market).
You're missing the point, Oli. The dragon platform is completely adaptable as a Mars lander. It also breaks ground on how we land on Mars.
Quote from: The Amazing Catstronaut on 04/30/2016 11:24 amYou're missing the point, Oli. The dragon platform is completely adaptable as a Mars lander. It also breaks ground on how we land on Mars.It's another one of those "build it and they'll come" arguments. The question is whether NASA actually has the need for a static 2t lander. Mars Sample Return is a planned NASA mission, current concepts are based on the sky crane system with a landing platform and a fetch rover. The entry and descent stage come at a cost of $220m, the cruise stage an additional $90m (both without reserves), given a total mission cost of $2.5bn that's not going to break the bank ($2.5bn is without orbiter or the Mars Returned Sample Handling facility). Maybe Dragon could be used for that, but I guess it would have be modified for a rover.Other than that, maybe drilling would be interesting, or landing at higher altitudes, but NASA doesn't have any concrete plans for those.
NASA has a need to save $$$, so by Red Dragon meeting their needs for less $$$, then why would NASA pass that over to do another SkyCrane more expensively?
We're already in a bubble of space investment, especially in launchers of any size, but also satellites, unmanned, suborbital, habs, etc. It may now be less of how much money will be pumped in, but rather when and how big the pull back will be when the bubble bursts.
I jut woke up to this thread, and I feel like I've happened on a SpaceX fan club party, at which most people have been drinking.

If no one else takes advantage, then it just ends up being a revolutionary precursor to whatever comes next.I hope it's the former and not the later...Hmm, so you're hoping that other countries or corporations will similarly try to make use of Dragon's capabilities, along with NASA?
Well, maybe Musk should enlist well known corporate entities and invite them to slap their logos onto the Dragon, NASCAR-style, so that their companies can proudly claim to have sponsored opening up Mars.
I'm not sure that's really Musk's style, but it could help to defray the costs of this mission - or at least pay for a SuperBowl commercial, or something.
But since SpaceX doesn't seem to be into courting customers heavily through salesmanship, maybe this is where a Golden Spike or someone similar could play the role that you want, to generate more missions.
how far will members of Congress, their largest current benefactors, and yes, some NASA employees go in maneuvering to counter this changing landscape? How far can they go? This outlier from Rep. Lamborn questioning how Musk finances his companies may be an overreach, but it won't be the last. What about the legions of Commercial and Government SpaceFlight Think-Tanks, Groups, Lobbyists? And how will other major Space Agencies from around the world view, respond to this? How will this impact other spaceflight/craft/launch companies? How will they respond?
Whether Dragon could provide the same capability for less $$$ is pure speculation, as this entire thread.
Sure, why not? Company logos are plastered on the sides of payload fairing already.
If a country or company came to SpaceX and offered to pay for a trip to Mars, what do you think SpaceX would do? I think they would take the money and say "When do you want to go?"
Don't be so sure that Musk is not courting potential customers already. This Red Dragon mission has been in the works for two years now, and now that it's plastered across the web and looking like it could be a reality I think Musk's efforts will be able to be ramped up in his private conversations with people.I'd be surprised if someone else offered to partner with SpaceX on a second mission before the first one succeeds, but once the first one succeeds then I would expect to hear about other partnerships for missions to Mars.
Every once in a while, something significant happens. And while it may be recognized for being so, only through the passage of time is it revealed to what extent it changed....well, everything.Of course, I'm referring to the SpaceX announcement of Red Dragon in 2018. However what intrigues me the most is, "What happens next?" Not with regards to mission planning but from a more general science, culture, business, politics and even international relations perspective.The context: For the first time in history a privately owned and operated company has the will and the means to land a sizable spacecraft on another celestial body. Plans and capabilities untethered to the mood of the country, or that of its' President and elected Representatives. What are the implications of such an endeavor and those that follow, not being within the purview of Congressional control through funding and direct oversight? What new rules of engagement will manifest? New lines will be drawn, new alliances forged, old power structures defended yet inevitably breached. Or not?For instance, how far will members of Congress, their largest current benefactors, and yes, some NASA employees go in maneuvering to counter this changing landscape? How far can they go? This outlier from Rep. Lamborn questioning how Musk finances his companies may be an overreach, but it won't be the last. What about the legions of Commercial and Government SpaceFlight Think-Tanks, Groups, Lobbyists? And how will other major Space Agencies from around the world view, respond to this? How will this impact other spaceflight/craft/launch companies? How will they respond? Will they need to? We here at NSF are an informed lot and I believe we share some responsibility to help inform others and when possible, direct the conversation in a meaningful and thoughtful way. So please keep things civil and help me and many others wrap our heads around, "What happens next?"
How is it untethered to government control? If the government cancels commercial crew, doesn't allow free access to the DSN and stops being SpaceX's number 1 customer, Red Dragon is probably not happening. If the ISS market doesn't support dragon production for cargo and crew launches, then the capability of SpaceX to support the continuation of the product line, including the Red Dragon variant, is questionable at best.

If the 2018 Red Dragon is successful, since it is a capabilities demonstrator, the next flight or flights in 2020 would be for paying customers like everything else SpaceX has done in the past. By teaming with someone like Spaceflight Industries a Red Dragon with 75 experiments at a average price per flight for each of $2M would probably have a waiting list such that in 2022 they could launch a Red Dragon flight every 2 weeks over a period of nearly three months.
If NASA wants or someone else wants a MSR that would use nearly all the landing payload of the RD (2mt for MAV). So for a MSR those would be dedicated designs like a CC version of D2 would be vs a Cargo D2.

This is a game changer if it works. People will focus on payloads. As they should. Dragon certainly could be modified to carry rover(s) 5 rovers for the price of one.
If initial RD EDL works, it will move into the "acceptable" category alongside skycrane (~$350M+). Might even be able to use it for "hard" spots that skycrane can't do (landing in open lava tubes, Hellas Basin, Valles Marineris, ...).

Wouldn't a Red Dragon landing be much simpler and more straightforward? Even if SkyCrane's development costs are already done, wouldn't a proven Red Dragon end up being the method of choice, because its more conventional approach seems likely to be more reliable (will have to wait for actual landing to know for sure). But in what scenarios would you want to use SkyCrane instead of Red Dragon?

This is a very new paradigm. This makes the potential to at least survey for resources on Mars or the Moon for significantly less than than the costs of a communications satellite until recently. This doesn't make exploitation affordable yet, but at least some resource companies with vision (say like BHP Billiton who in the 90's poured $1.5B into setting up a diamond mine a degree or so south of the arctic circle in Canada's Northwest Territories) would probably risk a quarter of a billion to stake out Lunar resources at the poles

Or when you're not as worried about contaminating the site with rocket fire, which was why the Skycrane doesn't touchdown at the same spot as the rover.

If there were no other considerations except efficiently getting the results you want from space then if you consider that there is a 25% probability of the capabilities that SpaceX is promising and a 50% chance of a split between current capabilities and those advertised then it makes sense to put as much attention to it as you do to the current systems. Ie plan half the new endeavours on it for now and take advantage of the cost savings to make it a 33% increase in total new endeavours than if you didn't have this capability to plan for.

Whether they should is another discussion--and certainly premature from the perspective of any existing and near-future programs until there is a credible capability.
Suggest that there already is enough reason for "credible capability". Except for glacial govt synapse firing and decadal survey pessimism. Oh, and CYA budget padding. Or am I being a bit on the harsh side here?
The SAA places RD in the category of COTS Commercial Cargo ("Resupply Service") to Mars (CRSM). RD would become a cargo provider for standardized form and fit "experiment packages" for delivery to Mars surface in the same manner that the same is being done for delivery of "cargo" to the ISS. First comes CRSM then later Commercial Crew to Mars (CCM)....

Have been in front of members of Congress.

One is ironclad but costly, the other is novel/less proven but economical.

You really don't think they will add new missions post the current ones? Then they really aren't serious about deep space. I would expect over the next 5 years that NASA will announce at least 5 new BEO robotic missions.
Then if it doesn't matter then go before congress and say hey we can give you our profound critical engineering assessment that going with the cheaper provider only adds a 25% risk of failure but a 75% chance that costs will be reduced by more than 25%.

I would expect over the next 5 years that NASA will announce at least 5 new BEO robotic missions.Sure, more BEO robotic missions, but not 5 to Mars--which are the ones which would benefit from this SpaceX effort. Or do you intend to expand the discussion to the entire solar system?
QuoteThen if it doesn't matter then go before congress and say hey we can give you our profound critical engineering assessment that going with the cheaper provider only adds a 25% risk of failure but a 75% chance that costs will be reduced by more than 25%.You willing to do that today? Or find anyone at NASA willing to do so? Good luck. And where do you get the "25% risk of failure but a 75% chance that costs will be reduced by 25%."
Quote from: Coastal Ron on 04/30/2016 03:51 pmIf a country or company came to SpaceX and offered to pay for a trip to Mars, what do you think SpaceX would do? I think they would take the money and say "When do you want to go?"That's the thing - who's just got all this cash lying around to throw at SpaceX to buy a trip to Mars? I thought countries do these things to show off their own accomplishments for national prestige. How are you going to summon up national pride just for having written a big fat cheque, as opposed to having done it yourself? That's like hiring athletes from other countries to represent you at the Olympics. What bragging rights do you get?
I think it would be cool if Google were to sponsor a mission to Mars.
Amazon is already sponsoring Blue Origin, in a sense.
If Google goes with SpaceX, then Apple will be under pressure to pair up with someone - Orbital ATK? Heh, and Microsoft can eventually join the party by tying with Stratolaunch.
... The fact that this event is this disruptive to the harmony of this forum makes me wonder what exactly Red Dragon is doing inside JPL. ...
Wow, incredible.This malaise of people grumbling at each other is only occuring on a fan site, with an even mix of professional industry insiders from just about everywhere and anywhere, spaceflight advocates, politicians, journalists, engineers, scientists, engineering students, a few gazillion dip-in fans and procrastinatory almost-millennials like myself. If Red Dragon has rocked the boat this hard on a forum, I can only imagine what it's done in-industry.
The fact that this event is this disruptive to the harmony of this forum makes me wonder what exactly Red Dragon is doing inside JPL. Extrapolate by several orders of magnitude.
One thing's for sure; this level of disruption is extremely healthy. Everyone is having their opinions challenged and is having to rush to substantiate them. Preconceived truths are being questioned. Preconceived interests are being redefined.
For many here what does not change is the "zero sum game". If I'm funded then you're not.
Generally agree with your sentiments... but who says this is "inside JPL"?
Note that RD work has long been done out of Ames, not JPL!
Guys, the world has changed with RD 2018; the prior lobbying groups are in the same space as buggy-whip manufacturers when Henry Ford introduced the Model T. OK, it isn't as simple as that - but, the old rules are no longer quite so important. Try to adapt to the new reality.

It's an annoyance in industry, as well as all the other newbies on the field.It scares the mission planners/middle managers because you don't know if it helps/hurts/curses your mission to bring it up in the first place. Many are used to getting shot at and have no stomach for it. While some have gotten that bullet and still trudge on.QuoteThe fact that this event is this disruptive to the harmony of this forum makes me wonder what exactly Red Dragon is doing inside JPL.

Also, there's a lot of "inside baseball" between centers/providers/vendors we can't/don't talk about. So there's a lot of "bad mouthing" that passes for informed opinion that IMHO goes too far, and what's behind it is the fight for who gets what mission and keeps alive N grad students etc.Never have the stakes been so low.Which some might rightly fear, could pull the funding rug out from under various mooted missions. Do not discard that lightly, its very real.For many here what does not change is the "zero sum game". If I'm funded then you're not.

Except for glacial govt synapse firing and decadal survey pessimism. Oh, and CYA budget padding. Or am I being a bit on the harsh side here?Don't see that... Imagine yourself in front of a Congressional Committee...- We're betting on Elon Musk and SpaceX for the success of X% of our Mars missions...- And your basis for making that bet?- We just believe because he said...Fat chance.While there may be many in these forums who would make that statement (and have zero career investment in the outcome), I doubt there are few (if any) at NASA. Nothing is going to change until well after SpaceX proves this capability.They're already cutting metal that will fly. That's the difference - SLS is simply cutting metal to build the jigs.
Hmm, so that's something interesting that I'd never considered before in regards to SpaceX and Red Dragon. NASA is not a monolithic entity, and there are different centers and different mission groups in contention with each other for funding and support to gain approval for their missions to go ahead.So SpaceX comes along and can now tilt the balance on that playing field. Does your NASA center or mission have a "SpaceX strategy"? If you don't, you might fall behind in the contest, and get shut out.Will all NASA centers and mission groups now each be trying to come up with a "SpaceX angle" to make their stuff happen? Could re-writing your mission proposal to take advantage of SpaceX capabilities now be the key to jumping ahead in the queue, or even holding your place in line?Will more and more NASA development be done in connection with interoperating with SpaceX hardware?It seems to me that the emergence of SpaceX capabilities on the scene is a great benefit to NASA program managers, because SpaceX is offering the opportunity of more-bang-for-buck, and the chance for them to fly when it might otherwise be denied.
I think that we should temper this with the realization that these advances are decades overdue, and were held back, not only by the lack of technology, but both the political and corporate interests that stood to lose their substantial economic wind fall
We've KNOWN reusable space craft were possible as far back as the X-15 space plane, yet this was a technology never pursued.
Quote from: ncb1397 on 04/30/2016 05:46 pmHow is it untethered to government control? If the government cancels commercial crew, doesn't allow free access to the DSN and stops being SpaceX's number 1 customer, Red Dragon is probably not happening. If the ISS market doesn't support dragon production for cargo and crew launches, then the capability of SpaceX to support the continuation of the product line, including the Red Dragon variant, is questionable at best.If the government cancels commercial crew, SpaceX will make Dragon 2 anyway, because it is part of their path to Mars, and it can be used for transport to future commercial space stations (Bigelow). Dragon lab is still on the manifest as well. Reduced demand for Dragons would probably up the per unit cost, but SpaceX still could fund occasional Dragon missions from its own profit.Without free access to the DSN, SpaceX would pay for access, or build their own relays depending on how the cost works out. SpaceX doesn't need NASA or the government in general as an anchor customer at this point. Take a look at the manifest for the rest of the year, out of 14 planned flights, there are 2 Dragon missions, the falcon heavy demo, 2 foreign government missions, and 9 commercial. The government is NOT SpaceX's number one customer anymore. (this doesn't mean that government contracts aren't lucrative, since gov't pays more to impose special requirements, which in turn means more profit, plus gov't will partially support development)I am not saying that SpaceX losing all of its NASA support and government missions wouldn't slow down SpaceX's plans, but they would still be making plenty of profit which they would then reinvest into the Mars missions. (SpaceX's balance sheet has always been effectively 0, since they redirect any profit directly into R&D and capital, that plus being a private company makes it hard to tell how much they really net on a single launch, but they clearly get enough based on the amount of side projects they have)

Revenue loss and job cuts are usually not the things companies are very keen to do. To date there's no indication that the launch market will grow.
So you just erased the Shuttle from the history books because it doesn't suit your agenda. Great.
SpaceX is paying for Red Dragon itself using revenue it generated from its business, which includes NASA, DoD, and commercial missions. It is most certainly NOT being paid for by NASA. Dragon was developed using funding from both SpaceX and NASA (skin in the game), with the idea that there are other customers for the capability besides NASA. In this case, the other customer is SpaceX themselves.It's a huge distortion to say that NASA paid for Red Dragon.
Question: Since commercial companies are required to contribute financially to develop and operate their own systems transportation system, how much are commercial partners expected to contribute in cost sharing with NASA?Answer: NASA is not going to dictate the amount of industry investment that should be provided. Each proposal will be evaluated on a case-by-case basis.
To be fair, the US Space Shuttle seemed to require much more refurbishment than vehicles like F9R are supposed to.

The way I look at this whole "who paid for what", is that unless you can find a purchase order or contract from the government authorizing payment to SpaceX for a product or service, then SpaceX funded that product or service themselves. End of discussion.

I believe COTS phase 1 was the only round that Dragon was involved with that required cost sharing.
There is no requirement in CCtCap milestones for cost sharing on development milestones.

It would be like me claiming I own the USS Carl Vinson aircraft carrier because my tax money obviously was used to build it.
As to PICA, which I know about personally and from the team that originally did it, AFAIK it was developed, built, used and abandoned long before Musk did anything with it. To my knowledge no NASA efforts to take PICA forward at the time, or now.
Which contract do you want me to point to? CCtCAP, CCiCAP, CCDEV2, COTS phase 1, COTS phase 2? I believe COTS phase 1 was the only round that Dragon was involved with that required cost sharing.

To my knowledge no NASA efforts to take PICA forward at the time, or now.Um no, that is wrong. PICA has been under continuous evaluation and development by NASA since it was launched on Stardust on 1999 and returned to a desert in Utah in 2006. You can find related contracts with Boeing, FMI etc going back through the last decade, under CEV or Orion ADP names.EDIT: even more specifically. At least one Boeing/FMI contract ran let in 2006-2009, there was plenty of other downselection work invested in as well. PICA got other reasearch ( carbon nanotube thingamajig because that was hip ) under NASA funding during that time.
To say that 'NASA abandoned' it is just wrong. Quite the opposite, they set out with an explicit goal of revitalizing ablative TPS industrial base.https://solarsystem.nasa.gov/docs/pr530.pdfEDIT2: And for reference, here is the SpaceX pica story:http://uknowledge.uky.edu/cgi/viewcontent.cgi?article=1029&context=ablation
NASA has not driven research to develop PICA as a TPS for its HSF vehicles, but instead relied on industry for direction.
It is not in the interests of industry to see PICA compete with, say, Avcoat.
You can fault my post for not being specific enough ... And that is what the "tempest in a post" is likely about. Have we done this well enough yet?
As to PICA, which I know about personally and from the team that originally did it, AFAIK it was developed, built, used and abandoned long before Musk did anything with it. To my knowledge no NASA efforts to take PICA forward at the time, or now...Otherwise it would be a loss for NASA and SX. Which would be dumb....So after the fact making a reassessment of value, after someone has discovered value in something abandoned and then making such an argument, is very disingenuous at the least.

Not only does SpaceX have rivals but new companies selling new goods and services are being created. The centre can now buy things that previously it would have had to spend time developing itself.The other strategy changer is tiny satellites like cubesats. Instead of having to procure a $70 million launch vehicle, which requires Congressional approval, the entire project can be built and launched for a couple of million dollars. 'Small' projects can be approved by NASA's Administrator. (He can negotiate a general budget with Congress.)
As someone in IT, it's pretty common to see situations where managers will keep going back to the vendors and platforms they have the most experience with, rather than just trying any old new thing. You go with who/what you know - especially if you're job's on the line if it doesn't work out.
But it will be harder for NASA people to adapt themselves to any old system from the broader New Space provider pool, as contrasted with building familiarity with particular vendors like SpaceX and preferentially using their stuff.As someone in IT, it's pretty common to see situations where managers will keep going back to the vendors and platforms they have the most experience with, rather than just trying any old new thing. You go with who/what you know - especially if you're job's on the line if it doesn't work out.I've seen plenty of discussion on this forum where people will mention the heritage of a particular platform, which informs its reliability, and how new development is usually done off some previous heritage platform. So the same thing would likely be the case with NASA making use of 3rd-party hardware from New Space vendors.If you've already used SpaceX hardware in doing your past 5 science missions, who're you going to go with for #6 - some new untried vendor, or SpaceX which has worked for you in the past?That's where these other guys like Orbital ATK, etc better develop some specialty niches for their offerings, if they can't compete with SpaceX head-on on most mission types. Otherwise, SpaceX will clean up and sweep the field.
Yes. Old saying in IT... "no one ever got fired for buying IBM" ... not as true as it used to be, we compete on merit like everyone else these days, but it's definitely something that people do, sticking with the safe supplier.
It's too bad that there aren't more deep-pocketed internet billionaires out there interested in becoming rocket engine-makers primarily, since engines are the key building blocks, just like computer processors. If you focused all your efforts purely on building better rocket engines, maybe the (New Space) world would beat a path to your door.

Because chances are you'll end up with a fun technology demonstrator that goes nowhere but to storage.Anyway it seems like there are plenty of new rocket engines being built using new fuels and processes and scales. Aren't we covered there already?

Tend to agree with the Ghost that going too far down the "did NASA fund this, how much" rathole is off topic.
Agreed. As a general rule, the existence of rockets, trumps the existence of a surplus of engines. The two need to be roughly equivalent to each other, or, at the very least, you manufacture an engine with the expectation that it might end up mated to an LV. Even tech demonstrators need some scent of an evolutionary of path to practical use.After all, a rocket without a rocket is a rocket to nowhere. As for LVs, you have people like Jim who would argue that the market is oversaturated for LVs already, and people like the guys running Electron or Blue who believe the world will have a niche for more LVs. As to who is right - it's probably somewhere in the middle. One thing's for sure though, not every engine in development right now is necessarily going to fly (*cough* AR1 *cough cough*).

I totally disagree. BE-4 is the one they actually want to use.
