Elon said in an interview today that he hopes to describe the next gen launch vehicle and spacecraft (presumably BFR and MCT?) later this year at IAC 2016, which is late September:



Starts at about 30:40 in the video.

Does a SpaceX board member count as "source"? Steve Jurvetson had a few words to say just after accepting an award for SpaceX:

This thread hasn't been updated for a while (so there may be some public details that have been missed), but here's something new:

a few more teasers before the september reveal:

1 red dragon in 2018, 'at least 2' in 2020, then first flight of MCT in 2022...

Not source information about the MCT/BFR per se, but about Musk's Big Unveil.

IAC Congress schedule (scroll down):

Friday, September 30 at 8:30 to 10:30 -- Late Breaking News: Elon Musk Space X Title to Be Confirm - Mars

So two hours on the final morning of the congress.

Just to clarify, the conference is on CDT, one hour later than EDT

IAC 2016 PLENARIES AND HIGHLIGHT LECTURES

Tuesday September 27
13:30-14:30 CDT = 14:30-15:30 EDT
Colonizing Mars -- A deep technical presentation on the space transport architecture needed to colonize Mars (SpaceX late breaking)

Is this in addition to the previously known Friday 8:30-10:30 CDT = 9:30-11:30 EDT session?

Probably won't be called MCT. Maybe something like Interplanetary Colonial Transporter:

Turns out MCT can go well beyond Mars, so will need a new name…

Hi Mr. Musk,
how about "Interplanetary Colonial Transporter" ?

Apparently it's officially being called the Interplanetary Transport System now.

Elon Musk on Twitter:
SpaceX propulsion just achieved first firing of the Raptor interplanetary transport engine
https://twitter.com/elonmusk/status/780280440401764353

Production Raptor goal is specific impulse of 382 seconds and thrust of 3 MN (~310 metric tons) at 300 bar
https://twitter.com/elonmusk/status/780275236922994688

Sorry of crossposting this, but thought that this would be relevant to both the Raptor and the MCT/bfr source information threads.

MCT (or ITS) suddenly looks a lot more doable.

Interplanetary transport system, here we come! 👍

Chamber pressure is almost 3X Merlin, so engine is about the same size for a given area ratio

Elon Musk on Twitter:
382s is with a 150 area ratio vacuum (or Mars ambient pressure) nozzle. Will go over specs for both versions on Tues.

@davidkyoon
@elonmusk Sweet Jesus, that means you are pumping to 45-50 MPa... Surely this will be using multiple stage pumps?

@elonmusk
@davidkyoon yes

@williamwinters
@elonmusk @rocketrepreneur based on your other specs, is that like a ~14 foot diameter nozzle?

@elonmusk
@williamwinters @rocketrepreneur pretty close

That thrust level of 3MN vac sounds consistent with the 2300 kN number we have heard before having been the SL thrust target so the engine size dose not seem to have changed much if at all, though I would not be surprised if the SL thrust ends up being around 2500 kN in the end.

2 Stages. MCT is second stage.

@elonmusk:
12m rocket booster diameter, 17m spaceship diameter, 122 m stack height.
The space ship is an odd shape with the main body cylinder being roughly the same 12 meters as the booster.

BFR returns to launch site after launch.
42 engines on booster!
On orbit refueling for the MCT.

Booster has 127,800 kN (28,730,000 pounds) of liftoff thrust. Booster lands exactly on launch mount (risky!).

MCT has 200kW solar panels.
MCT coast speed 100,800 km/h

Re- entry temperature at mars: 1700 C (3,092F).

Spacecraft in video are from actual CAD models.

100 people per flight, maybe 200 later.

Built mainly of carbon fiber. Making cryogenic tanks from carbon fiber is hard, only recently achieved.
Gasifies fuel and oxidizer with engine heat and uses that to pressurize tanks.

550 tons to LEO in expendable mode. 300 tons in reusable mode.

Only the central seven engines gimbal. The others are fixed in position.

3 sea level engines, 6 vacuum engines. Sea level engines gimbal, in space steering with differential thrust of vac engines.
Initially 100 passengers per ship, but number may grow to 200 or more.
