How to pay for it....

Smaller vehicle.  Sub-scale BRF confirmed. 

Small BRF can do "greater Earth orbit activity."

We want to make F9 and FH and Dragon redundant.

If they can make F9, FH, and Dragon redundant, all resources can be applied to sub-scale BFR.

Propulsive landing:

To land on Moon/Mars, you have to get propulsive landings right.  That's what we've been practicing with F9.  16 successful landings in a row.

That's without redundancy.  F9 lands on single engine.  BFR would have multi-engine out landing capability.

Aiming to get propulsive landing perfect. (That'll be for the launch mount return).

BFR won't need legs.

"We can get to landing reliability on par with safest commercial airliners."

We believe propulsive landing precise is so great that it will land back on its launch mount.  It won't need landing legs.

200 bar for current Raptor tests, flight pressures of 250 with a goal of 300 bar.

That's 2900 psi current, 3625 for flight chamber pressure, and 4351psi for their goal chamber pressure.

Next key tech is automated rendezvous and docking.  This has to be very high precision for propellant transfer.

Dragon 2 will do completely automated berthing tech.  Won't need Canada arm like Dragon 1.  "Just press 'go' and it will dock."

We started off with a few people who really didn't know how to make rockets. I ended up being chief engineer because we couldn't get anyone to join. I messed up the first three launches.  Fortunately, the fourth launch worked or that would have been it for SpaceX.  Fate liked us that day.

Today is the 9th anniversary of the first successful SpaceX launch.

Falcon 1 small compared to Falcon 9.

F9 is 30x more payload than F1 and reuse of first stage (and hopefully soon of the fairing).  Hoping we can get ot 80% reuse of the F9 systems.

Think of BFR crew/cargo vehicle as if Dragon and Stage 2 never separated and operated together.

"You can fit a whole stack of Falcon 91s in the payload bay of BFR."

825 m3 - bigger than pressurized area of A380 aircraft.

In Mars transit config, 40 cabins and large common areas, central storage, galley, and solar storm shelter.

2-3 ppl per cabin.  About a 100 people per flight to Mars.

40 cabins for crew transport. Could have five to six in a cabin, but expect 2 to 3. 100 people to Mars. Entertainment area. Solar Storm Shelter, etc.

And the business end:

Can land with either one of the two center engines.

Both will lit, but it one fails, BFR can land with just one sea-level Raptor engine.

Refueling - ships mate at the rear, same mating interface with Booster.

Use control thruster to accelerate in the direction you want to transfer propellant toward.

BFR has more capability to LEO than Saturn V -- even with full reusability AND FAR CHEAPER.

Value of orbital refueling:

If you just fly BFR to orbit, you'll get 150t to LEO and have no fuel to go anywhere else.

But if you refuel tanks all the way to the top, you can get 150t all the way to Mars.

If tanker has high reuse factor, than the price drops.  LOX and Liquid Methane are very inexpensive.

Offline Chris Bergin

150 mt to LEO. Then refil to get 150 mt to Mars.

So... how do we pay for this system....

This was a profound breakthrough.  If we can build a system the makes our own products redundant, than all the resources for F9 and FH can be applied to one system.

Some of our customers are conservative, want to see BFR fly several times first.

Will have a stock of F9s and FHs so customers can keep using those if they desire.

We will then move on to BFR and pay for it by contracts for sat launches and servicing the ISS.

Offline Chris Bergin

The key to paying for all of this is to kill Falcon 9 and Falcon Heavy. Go to one system for everything. Will build a large stock room of "old" rockets and then only build BFR from then onwards.

For BFR launching sats, we can send 9m diameter objects into orbit.   We could launch a Hubble with a mirror three times larger than Hubble's current mirror.

We can launch multiple sats in one launch.

We can use it to retrieve sats and bring them back -- clean up LEO.

Can also service the Space Station.

MOON:

Lunar surface mission w/ no prop production on the moon.

High elliptic-orbit re-filling.  Than go all the way to the moon and back without refueling on the moon.

That will allow for the creation of Moon Base Alpha.

MARS:

Being a multi-planet species beats the hell out of being a single planet species.

Mars plan is same as before.

Refuel in Earth orbit.  Go to Mars.  Land.  Produce fuel on Mars from CO2 and H2O to make Methane and Ox prop.

Long term... this fuel production can be done on Earth.

Use solar power to extract CO2 from the air.  Same thing we do on Mars we can do on Mars.

Need to build prop depot on Mars.  Because Mars has lower gravity, you can go from surface of Mars with 20-50t payload all the way back to Earth.

Mars atmospheric entry will have ablative element to heat shield.  But heat shield will be multi-use.  Then supersonic retro propulsion... and landing.

Over 99% of energy removed by Mars' atmosphere during entry.

Construction of first BFR begins Q2 of next year, 2018.

Complete ship and be ready to launch in 5 years.

5 years seems like a long time for Musk.


OH.... AND THAT'S TO MARS!  2 CARGO BFRs to Mars in 2022.  And 2024, 4 BFRs.

First two find water.  Second four construct prop depot.

Streamed live starts at 42 minutes into the video.

This week at the International Astronautical Congress (IAC) in Adelaide, Australia, SpaceX CEO and Lead Designer Elon Musk will provide an update to his 2016 presentation regarding the long-term technical challenges that need to be solved to support the creation of a permanent, self-sustaining human presence on Mars.

You can watch the talk live on this page on Thursday, September 28th  at 9:30 pm PDT, or Friday, September 29 at 2:00 p.m. ACST.

I imagine this is on a discussion thread somewhere (haven’t had time to catch up yet) but think worth posting here for reference:

How do you make the high g-forces of rocket liftoff comfortable for every day travel? Will it just become something we get used to?

Assuming max acceleration of 2 to 3 g's, but in a comfortable direction. Will feel like a mild to moderate amusement park ride on ascent and then smooth, peaceful & silent in zero gravity for most of the trip until landing.

There seem to be two cutaway view renderings to the spaceship one with the oxygen fuel tank just below a single cargo deck and one with two cargo decks.
Any idea as to which is the "correct" one?

From the look of it, all the bulkheads and tanks appear to be in the same locations.

Initially, I too assumed it was cargo, but packed around the top of the LOX tank.

I took one of the other slides, the 'Refilling' one, and blew it up to get a better look. Based on that, I think that the space around the top of the LOX tank is an equipment bay. This could be the life-support machinery and tankage.

I've blown up and enhanced part of the image to make the structures inside the area clearer. They do appear to be a collection of boxes and spherical tanks. The spherical structures resemble tanks more than regular cargo, that leads me to believe that the area is an equipment bay, rather than a storage area.

Maybe I missed something, but this seems exactly like a rehash of the September conference details with no new information.

Right, and this isn't a small group in aerospace. Imagine writing a proposal that might require BFR or New Armstrong or something and pointing to a YouTube link (or just an NSF forum post about New Armstrong rumors) as a reference.

elonmusk Zero gravity violin concerto in Earth orbit before departing to Mars
You want to be inspired by things. You want to wake up in the morning and think the future is going to be great. That's what being a spacefaring civilization is all about. It's about believing in the future and believing the future will be better than the past. And I can't think of anything more exciting than being out there among the stars.

I'm surprised the violinist is playing left handed. Even left handed violinists usually play right handed. So this is only slightly more likely:

I can't make that geometry work, if I assume that's in a BFS, even if the windows have grown considerably.
Making her very, very short might help.
Perhaps a glimpse at some sort of orbital depot?

As a nitpick, a concerto can't be by one performer.

That's the ITS window, not BFS, isn't it?

Hmm, maybe a cosplay costumer to go as well? The skirt cannot be assured of that flow. Air would move the payer. Wire stays in the costume may not flex enough. Memory wire and a battery pack might suffice.

How to pay for it....

Smaller vehicle.  Sub-scale BRF confirmed. 

Small BRF can do "greater Earth orbit activity."

We want to make F9 and FH and Dragon redundant.

Whatever happened to the small scale BFR?

Construction of first BFR begins Q2 of next year, 2018.

Complete ship and be ready to launch in 5 years.

5 years seems like a long time for Musk.


OH.... AND THAT'S TO MARS!  2 CARGO BFRs to Mars in 2022.  And 2024, 4 BFRs.

First two find water.  Second four construct prop depot.

Those are in Elon years.

Errr...  You're looking at it?  BFR was 12 m diameter in 2017...

Would you like an even smaller one than the current 9 m?

Since the T-Mobile announcement Danderman has enthusiastically been searching for reasons to stretch out the planned Starship development timeframe.

It has something to do with the window of opportunity needed for Lynk to gain a foothold in the market before Starlink V2 is operational.

However, dredging up a post from back in 2017 is certainly a new level of…dedication?
