I think the CAIB determined a Shuttle rescue mission for STS-107 was possible, but was right at the razor's edge of being possible. Does anyone really not think the folks at KSC, JSC, and MSFC would have moved heaven and earth to get Atlantis off the pad in time? They would have even had retired Shuttle engineeers and techs coming to the gates volunteering to help. NASA would have worked day and night doing only what was necessary for the rescue mission in an effort to save the lives of Columbia's astronauts. The US would never have gone to such extremes to rescue an unmanned Russian exploration vehicle.

Typical turn- around times were quite a bit longer than this. Sorry, but the shuttle was not a fast turn-around vehicle. In a situation like this, where there is a "need" to launch in only a few days, the shuttle simply could not accommodate this requirement. LEASAT F3 rescue mission took several months to plan and fly. In this case, the Russians don't have months to spare, they have only a few days. Jeff, you're missing Mike's point by a country mile: he explicitly conditioned the rescue mission on Russia being able to gain enough control of the spacecraft to boost it into an orbit that would last long enough that a fast turnaround shuttle mission would *not* be required. You spent several paragraphs going down the fast-turnaround rabbit hole without even reading what he wrote. I trimmed his response down to the relevant paragraph so you can read it (perhaps for the first time). My point stands, though: NASA would not agree to take the risk of this mission even if the shuttle were still flying, and even if Phobos-Grunt were boosted to an altitude where fast turnaround were not required. |

They did it with the LEASAT/SYNCOM, which was 15,000 lbs (7 metric tons) of explosive fuel, and that was a satellite that was just as dead as Phobos-Grunt is now. Even prior to that on STS-51-A the WESTAR and PALPA satellites, though much smaller, also had explosive hypergolics, and those were brought back all the way to Earth for eventual refurbishment and relaunch. -Mike |
