If true, they don't have any reasonable idea the probability of failure of another Soyuz launch. Right now the Russians just don't know what they don't know. The 3. stage gas generator is being fingered. http://www.universetoday.com/88508/c...h-may-have-bee n-determined/ Makes sense, given the symptoms reported. But exactly what caused the gas generator to fail isn't reported in the above article. Still, it seems like the Russians have at least narrowed the problem down.

http://www.spaceflightnow.com/statio...27unmannedops/ I think they should immediately return as much crew as possible to minimize consumption, and have that commercial delivery take essential supplies to give the russians more time to fix the soyuz booster issue....... The last thing we need is a unmanned ISS that has tech troubles and gets out of control. dropping station modules all over its ground track worldwide....... What do they need by way of ground support? If they don't want to land in Kazakhstan in winter, they could land in Australia. Plenty of room here - much of the place is completely uninhabited because it's totally useless. Sylvia. |

This used to be possible, but that was decades ago. I'm not sure if the current "digital" Soyuz is equipped to fly unmanned. You'd have to ask the Russians. But even if you can fly it unmanned, it won't do you any good if the Soyuz launch vehicle fails again and it doesn't make it to ISS. Of course. But you'd have a test flight without endangering any crew and if it works you have a fresh Soyuz at the station, so the current crew can stay there longer. Anyway, being able to get an empty Soyuz to the station would be a capability that could be very helpful in many emergency situations (like having a docked Soyuz damaged or unusable in some other way). The Russians would be very wise to implement and test this if they haven't already.

Why do I get the feeling someone at NASA said this was going to happen but they were ignored - similar to the guy warning of the SRB problem before Challenger.... Incidentally, some people would blame Obama for cancelling the Shuttle program. The Shuttle fleet was kept running longer than it was really appropriate to operate it from a safety viewpoint. So it wasn't Obama's fault. And it is now too late to build more Shuttles. This doesn't mean that I'm necessarily putting the blame on Bush. Those who wish to blame the Democrats for everything may take solace in the possibility that this threshold was crossed back under Clinton. John Savard |

For example, if 1000 engineers "predict" a total of 10,000 different failures modes, that doesn't mean that NASA has the resources to adequately address them all. Well, then the United States has two choices. Give NASA those resources, or don't fly that thing. Of course, it isn't really that simple. It is reasonable that unlikely and unforeseeable failures can happen - ones that can perhaps be envisaged in theory, but which are so unlikely that they were never expected in practice. I think people can understand that. So the voters aren't totally unreasonable. They might just want to hold NASA to the same standards as, say, they hold a mass manufacturer of consumer products like automobiles. Which is only a little unreasonable. John Savard |
