"Thomas Cuny" wrote in message om... Move HST to ISS. Service HST. Can the HST function in ISS's orbit? How much effort would it be to move HST? Essentially, you'd have to land HST and then launch it again into ISS orbit. And the only vehicle capable of that is the Shuttle. (I'm not even sure if the Shuttle could reach the ISS orbit with the HST payload.) It takes a lot of fuel to change your inclination while in orbit Bruce |

Can the HST function in ISS's orbit? How much effort would it be to move HST? Far too much. It would be easier in some ways to de-orbit the thing in a shuttle and relaunch it to ISS. (in terms of fuel required.) |

The head of NASA was asked about that at this afternoon's press conference.
Basically, he said it would be difficult and the HST might die before they could arrange it anyway. What about using electrical powered engines ? After all time in on our side in case... http://tinyurl.com/3drsh AlexT |

All of which doesn't address scheduling issues (how sure are we that it could be done in time). |

And just after Opportunity landed, Weiler, Theisinger and Elachi give O'Keefe a sign: http://spaceflightnow.com/mars/mera/...5officials.jpg ;-) |

agreed... but I was under the impression that those issues should be also solved for the "desorbit booster"... assuming one will be indeed built (I personally doubt it). I don't know how confident NASA is with it's ionic propulsion (seems that the latest test probes were quite successful) but I don't see any reason not to consider it... and actually decide which way to apply the delta V at a later stage !
