Discovery ET to be reinforced all the way around

That's still short of the on-orbit record of 437 days set by Polyakov on Mir. Means more food, water, and oxygen needs though, which in turn means more unplanned cargo flights. Since each Soyuz return flight will need at least one Russian aboard to pilot it, that also will leave the ISS top-heavy with American astronauts. It also means that you need four Soyuz spacecraft attached to it to evacuate everyone in an emergency (3 people per Soyuz max). Does it even have the ability to dock that many Soyuz at once? I thought it had two Soyuz docking locations, plus one for the Progress. Even if you dock a third Soyuz to the Progress docking collar how are you supposed to get cargo to it via other Progress spacecraft? Pat |

There won't be evacuation seats for everyone, the reason it will take a year is the construction lead time for the extra Soyuz. If there were that many already available then a couple would probably be minimum duration, launch, two days to dock, one to load passengers and any cargo, then straight back down. They wouldn't be left at the station. They might also make use of any ESA crew to handle return trips as they are trained as Soyuz Flight Engineers. Anthony |

Only one additional person (crew of seven instead of six.) Three will return to Earth on one of the Soyuzes immediately. NASA will plan for that, since Atlantis will be delivering an MPLM full of supplies anyway (if Atlantis returns fine, then the extra food is just deducted from subsequent Progress deliveries.) Not everyone will have a lifeboat. That's why the astronaut office is an all-volunteer force, however. There's no shortage of astronauts willing to take the chance. Brian |

Although the odds of the crew getting stuck at the ISS certainly are very small, if they do get stuck there you would be putting the ISS in the RMS Titanic scenario, with fewer lifeboats than needed to evacuate it in an emergency Who's supposed to choose which six can evacuate it, and which four have to stay aboard till two more Soyuz lifeboats arrive, or they die? This is a _very_ stupid idea, and the fact that it's being done simply to extend the Shuttle program a few months rather than out of any real necessity makes it doubly stupid. Frankly, I'm surprised the Russians didn't veto this extra mission idea the moment it came up. Pat Well imagine the worst happens shuttle stuck at station, not enough life boats and something bad occurs and 4 die, leaving a possibly out of control station losing modules all over its ground track as it breaks up.and re enters I believe that will end US manned space for generations. wierdly before coulumbia I was laughed at and called chicken little when I asked about a shuttle stuck at station. of course if any shuttle got stuck at station, the event itself would likely ground the shuttle. the real solution is russia having a few extra soyuz with boosters in stock for fast emergency launch........ |

Frankly, I'm surprised the Russians didn't veto this extra mission idea the moment it came up. This is getting to sound more and more like a "Jaws" type movie. Some know disaster is in the offing. But others given special interest just keep smiling and plowing ahead. Then one by one the dominos start falling and an not easily solved disaster unfolds. Astronauts trapped in orbit as we pray for the miracle of their safe return - kind of like a 1 year Apollo 13. My bet is right now out there some author is betting on the disaster and already has a book half written. "Against Stupidity The Gods Themselves Contend in Vain." Val Kraut` |

Only if one of the STS-135 crew is Russian; our guys don't know how to operate a Soyuz any more than the Russian cosmonauts know how to operate a Shuttle. So at the least, one Russian cosmonaut is going to be needed to bring two of our Shuttle crew home; and that applies to a second rescue Soyuz return flight also, so that all four Shuttle crew get home. Wait till you see the bill the Russians would send NASA for that little scenario. They'd _love_ the propaganda ramifications of saving the clumsy and inept Americans and their deathtrap Shuttle's crew with their reliable little Soyuz. Pat |
