Space first stage recovery.
I was really thrilled by the recovery of the Falcon 9 first stage last week. I thought it was the most exciting launch since the first launch of the Space Shuttle Columbia. At the time, I believed NASA which was saying that after an initial development period, the Shuttle program would launch a space ship about once a week. Lots of things would of been different if the Shuttle could have been launched affordably once a week. Now back to SpaceX. Does anyone know what is SpaceX's game plan with a recoverable first stage? They can just keep on as is and increase their profit margin. Or they can try to get more customers by lowering their price. They can also improve their rocket by tearing down the recovered first stage and scanning the pieces to figure out which need to be stronger which could be lighter or what not, that, at least in the short term, probably increases their costs per flight instead of lowering it. I suspect they will do a little bit of each of the above. But does anyone have clues of what they are doing? Is there any sign that they are offering flights for less than before? Alain Fournier |

Alain Fournier elon musk has said he not only wants to go to mars, but start a settlement there. given his big plans, i believe they will try to drive the price down, and whats his current price cut? its a lot I ant to see what space x does to develop a fast transit to mars system. cutting travel time from 6 or 7 months, tom 6 weeks will make mars so much more doable |

I was AT the Columbia launch and witnessed it first hand. For me, this was every bit as exciting, perhaps even more so. But the suspense was not as long, because at the time of Columbia there was a real concern about the adhesive used for the tiles and whether it was up to the task. I remember hearing back then a lot of talk about the "zipper effect" that might doom the shuttle. Quite a contrast from then 1980 to 2003. Dave |

With the shuttle, NASA designed the thing to only fly with people on board, so its first test flight was manned by Crippen and Young (if memory serves). With Orion, it looks like we'll get a couple of unmanned test flights (including the development flight that was on Delta IV). Jeff -- "the perennial claim that hypersonic airbreathing propulsion would magically make space launch cheaper is nonsense -- LOX is much cheaper than advanced airbreathing engines, and so are the tanks to put it in and the extra thrust to carry it." - Henry Spencer |

I don't see this coming about through incremental improvements in existing rocket designs. Sylvia. |

I don't see this coming about through incremental improvements in existing rocket designs. Problem easily solved... You get SLS into mass production in China. Mass production and China should lower costs. Second, you use an SLS to launch an SLS into Orbit. You use 4 SLS launches to haul fuel for that first SLS. So 5 SLS launches to get 1 SLS in orbit fully fueled with Orion at the top, ready to GOTO (not GOSUB) Mars lickety split. One SLS won't get an Orion to Mars in 6 weeks, even starting from Earth orbit. Further, you need to slow down before arriving at Mars (and no, aero-braking won't work at these speeds). Even if one SLS were up to the task of slowing down the Orion at Mars, you're now talking about getting an entire SLS there. How many SLSs would be required to do that from Earth? Now remember that you need to get the crew back in the same time. Pretty much, that means that however many SLSs you thought you needed from Earth now has to be placed into Orbit around Mars. To do that, you now need to square you previous number. Oh, no doubt it's technically possible, you just keep staging 'til it works. But the cost, even from China... Sylvia. |
