Dragon capsule reenters Earth atmosphere
The SpaceX Dragon capsule has landed off the coast of Californiyeeeah!
Congratulations to Elon Musk and NASA! It must be a sad day at Boeing where the EELV's will probably be replaced by Falcon 9, Falcon 9 Heavy. I wouldn't be surprised if the GAO and NASA will now seriously consider asking SpaceX to develop their Falcon X and Falcon XX on the cheap (a couple billion $). Compared to the dozens of billions Constellation was gonna cost the Federal government won't be able to resist this price tag. |

They made contingency plans for both one and three orbits in case something didn't allow them to land on orbit two, but two orbits is what they were shooting for. OK. Still, stick the "wings" on the next Dragon, put some nice but non-essential or at least easily replaced cargo into it, perform the planned second mission objectives (iirc, getting "close" to the ISS) and then if all goes well, go for the extra credit. If NASA lets them actually dock to it via the mechanial arm. Considering the far larger Japanese HTV-1 cargo spacecraft was allowed to dock to the ISS on its first orbital flight, I don't see how NASA can say that Dragon can't dock on its second orbital flight. I may be playing on stereotypes, and JAXA hasn't been without failures, and I don't really want to suggest overly "agile development" processes at SpaceX, but my peanut gallery gut tells me the Japanese were much more methodical about HTV-1 than SpaceX with Dragon. That said, I'd still love to see a docking on flight two. rick jones -- The glass is neither half-empty nor half-full. The glass has a leak.

I suspect they have a lot of input to the process. Pat |

Brian mike griffin head of nasa at the time picked the ARES launcher, the biggest crackpot idea i ever heard of. did it have many supporters here? puuting people on a solid booster? |

If a dragon at the moon was on its way back for re entry it would need a big heavy heat shield. but what if the capsule inflated a transhap type drag balloon immediately before rentry? would that transhab slow the vehicle enough so a heavy heat shield wouldnt be necessary? |

The original design, yes. Standard SRB and SSME for the upper stage promised low development cost and time, but NASA wimped out on trying to build that one and Ares I began its death spiral the moment SSME was canceled. At that point, the whole architecture should have been dumped, but NASA brass stonewalled the rest of the world that was saying "this design stinks." puuting people on a solid booster? On a proven SRB, though, not the "new and improved" 5-segment ("now with 20% more chances to fail!") Brian |
