DocM Share Posted September 18, 2016 (edited) Elon musk hinted that the Mars Colonial Transporter would be renamed in light of it now being capable of missions beyond Mars. Elon Musk ✔ @elonmusk Turns out MCT can go well beyond Mars, so will need a new name 8:22 PM - 16 Sep 2016 Elon Musk ✔ @elonmusk Maybe Ultimate Spaceship, Version 2? Mostly because it is not the ultimate and there isn't a version 1. 9:43 PM - 16 Sep 2016 Elon Musk ✔ @elonmusk Preview of the @SpaceX interplanetary transport system at @IAC2016https://t.co/Rz4XmeAoRw Edited by DocM, Today, 10:24 PM. When asked to confirm the name.... Elon Musk ✔ @elonmusk @thescalex @SpaceX @IAC2016 @YouTube ITS it is The Interplanetary Transport System reveal at the International Astronautical Congress in Mexico on Sept. 21 will be part of a larger presentation about colonizing Mars, but clearly other destinations are on the table. Certainly Ceres, Vesta and other asteroid belt objects come to mind, but so does Jupiter's remote moon Callisto, which has an even more benign radiation environment than Mars. 3rd largest moon in the solar system, it's almost as large as the planet Mercury.

Unobscured Vision Share Posted September 18, 2016 Omg omg omg omg omg omg nom nom nom nom .... Okay .. I'm okay .... I get home from an overtime shift at work and I see this ... /happydance ... thank you. I vote that "BFR" is now that moniker meaning "Booster For Real" as in "We're not mucking about now". And with the updated Mission Set(s), we (as a Species) really aren't mucking about now. 3 Share Link to post Share on other sites

Unobscured Vision Share Posted September 18, 2016 ^^ And 5/6 of it will be reuseable. ^^ Only portion that isn't is the fuel. 2 Share Link to post Share on other sites
DocM Author Share Posted September 18, 2016 (edited) THIS IS NOT OFFICIAL, but someone rolled up all the rumors and generated a notional graphic to show the expected scale of ITS. No details on the vehicle, just an outline, and the interstage is probably way too long and the "fat" part of the booster too short. We'll see how this holds up.

Unobscured Vision Share Posted September 18, 2016 (edited) The S1 probably will look much like that. Beyond that, no. The S2/Spacecraft Section won't have a Fairing, for certain. It's far too large to produce on that scale, not to mention wasteful .... Unless they've figured out how to get Fairings back. [EDIT] Looking at the S1-to-Transtage section, it's likely that it won't taper towards the top like that. They need all the LOX they can carry. Expect it to remain the same diameter throughout the entire length of the vehicle. 1 Share Link to post Share on other sites
DocM Author Share Posted September 18, 2016 (edited) They're working on fairing recovery, with recent launches having fairing halves with attitude control thrusters and hitting the water intact. Later they'll add GPS guided parafoils and recover them. Saves a few $million a launch. 1 Share Link to post Share on other sites
Unobscured Vision Share Posted September 18, 2016 Sweet ... I wonder when they'll test out the parafoils. Knowing SpaceX and the tendency to "put several eggs in a basket", the RTF in November/December when they test a few other goodies? Link to post Share on other sites
DocM Author Share Posted September 18, 2016 (edited) The parafoils are based on off the shelf items from Airborne Systems, the same outfit that has made large chutes for the military, SpaceX, Boeing and NASA. Similar to JPADS, GPADS and their DragonFly line. http://airborne-sys.com/product/dragonfly/ Dragon recovery system http://airborne-sys.com/space-recovery/ Edited September 18, 2016 by DocM 1 Share Link to post Share on other sites

Quote Scheduled for Sep 27, 2016 SpaceX Founder, CEO, and Lead Designer Elon Musk will discuss the long-term technical challenges that need to be solved to support the creation of a permanent, self-sustaining human presence on Mars. The technical presentation will focus on potential architectures for sustaining humans on the Red Planet that industry, government and the scientific community can collaborate on in the years ahead. 3 Share Link to post Share on other sites

DocM Author Share Posted September 26, 2016 (edited) Yay!!!! @elonmusk SpaceX propulsion just achieved first firing of the Raptor interplanetary transport engine https://t.co/vRleyJvBkx @elonmusk Production Raptor goal is specific impulse of 382 seconds and thrust of 3 MN (~310 metric tons) at 300 bar 310t = 694,400 lbf 300 bar is 4,351 psi/30 MPa. More chamber pressure than the Russian oxygen rich stages combustion engines. Mach diamonds Edited September 26, 2016 by DocM 1 Share Link to post Share on other sites
DocM Author Share Posted September 26, 2016 (edited) @elonmusk Chamber pressure is almost 3X Merlin, so engine is about the same size for a given area ratio @elonmusk @rocketrepreneur 382s is with a 150 area ratio vacuum (or Mars ambient pressure) nozzle. Will go over specs for both versions on Tues. Edited September 26, 2016 by DocM 1 Share Link to post Share on other sites
DocM Author Share Posted September 26, 2016 @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 1 Share Link to post Share on other sites

Unobscured Vision Share Posted September 26, 2016 Yep, just reading about this. Wonderful achievement, and so much potential for up (and down) scaling the technology! And it's insane how much kick ITS is going to have at upper altitudes from these engines .... oof. Those updrafts are going to be absolutely critical getting all of that mass uphill. Moreso than Apollo/Saturn. There's much more mass it has to push in comparison ... it needs all the lifting tricks it can take advantage of. @John. That's gonna be towards the end of the event, I believe, when Elon makes the presentation for all of that. Link to post Share on other sites

Unobscured Vision Share Posted September 26, 2016 2 hours ago, DocM said: 310t = 694,400 lbf Niiiiiiiiiice .... We knew it was going to be 500k~650k per engine, but 694,400 +/- ... overachievers. Now if the engine layout guesses are correct for the S1, we can plot the liftoff power. And since we now know the desired specific impulse, we can roughly determine how much fuel it'll require -- and how big those S1 tanks will probably need to be. One thing's for sure ... the Saturn V's S1 + S2 is gonna look cute by comparison. Link to post Share on other sites
