Shuttle program extension?

While continuing the shuttle reduces the requirement for us paying for rides, rescue seats home are still required. (Though one could argue that at some point one may want to simply accept that lifeboats aren't required for 100% of the crew.) Never gonna happen. That's a political non-starter. Brian |

Which is one of the reasons that our space policy is such a disaster. |

The closest to being made was the scaled-up X-24 lifting body design based one. That got as far as landing drop tests under its para-sail; then just went bye-bye, never to be heard of again. Your tax dollars at work: ten million here; ten million there; nothing at the end to show for it. Once again - like all NASA manned spacecraft designs since the Shuttle. Pat |

Pat Moose would be a nice option. Frankly the station is a looser What if congress just canceled all remaining shuttle flights, and gave the staioin to the partners? the boatloads of money could be used to build something new, unsure if nasa is capable of that the institution is way too forcused on pork piggies, exploration and science are dead last priority wise. the only loosers would be the unemployeed workers, nasa produces little of value since its mandate got changed to PORK |

X-38 did get a lot farther than the others, though. They were building the first orbital version when the program was cancelled. It's still sitting in storage somewhere, evidently. Brian |

Funniest thing to come out of the Dean Drive madness (besides John Campbell taking another step down hill in the eyes of the science fiction community) was that the United Statess Patents Office wrote Dean back saying he should get in touch with the mining industry , that he has a good invention for using on mining processing shaker tables! (I don't know if Dean ever followed up on this!) |

It's a political non-starter, but it's a bit silly. ISS currently had many redundant systems and modules. With the US and Russian segments, you have completely separate systems for life support. Even if something catastrophic happened, it's not very likely to take out both sets of life support systems. If safe haven wasn't such a political non-starter it would actually be a viable way to run the program without the US relying on the Russian Soyuz. Jeff -- A clever person solves a problem.

If safe haven wasn't such a political non-starter it would actually be a viable way to run the program without the US relying on the Russian Soyuz. And the reality is, given the current config, it's quite possible that part of a crew could be "stranded" on the wrong side of a problem. Suppose you've got 2-3 crew members in Zvezda and you have a fire in Unity and shut the hatch. You've got the rest of your crew in say Columbus. You're going to be hard pressed to "rescue" them. In my opinion, you really need a single Soyuz for emergency evacuation of a medically compromised cew member (and two others to help him/her during and after re-entry). Beyond that, if a problem occurs, you hole up and wait. It reminds me of Apollo 13. So many people think "great, they had a lifeboat". But had the tank problem occurred while the LM was on the surface, we'd have had 3 dead astronauts. It's nice to have backups, but you can't reasonably protect against everything.

Suppose you've got 2-3 crew members in Zvezda and you have a fire in Unity and shut the hatch. You've got the rest of your crew in say Columbus. You're going to be hard pressed to "rescue" them. True, that's a horrible scenario that even Soyuz doesn't solve. Too bad the docking and berthing systems on ISS aren't *all* compatible with each other. If they were, then Soyuz could be used to move them to the functional side of the station. But that still doesn't work if the fire strands everyone on the US side of the station. If that happens, the US life support systems had better be working.

But had the tank problem occurred while the LM was on the surface, we'd have had 3 dead astronauts. True. Sometimes you have to take chances when you're in the "wilderness". As an example, it's not very easy to evac someone from the base at the South Pole in the middle of winter. It's even worse for climbers on Mt. Everest. You screw up, you die.
