Why not reboost Hubble anyway if propellant permitting?

Good idea... http://www.nasa.gov/pdf/331922main_s...kit_050609.pdf .....After the work on Hubble is completed, Altman and Johnson will oversee Atlantis’ reboost of the telescope to a higher altitude, ensuring it will survive the tug of Earth’s gravity for the remainder of its operational lifetime. A final decision on how much altitude will be gained by the reboost will be dependent on Atlantis’ available propellant. |

Instead, Atlantis will lower its own orbit to reduce the risk of MMOD impacts. Brian |

I think one of the problems was that there is a lot of junk in slightly higher orbits and it would be doubly silly to both risk an orbiter, and the newly repaired Hubble by doing that, or at least that seems to be one of the factors. Its a bit of, if it aint needed, why bother sort of thing. lol, Brian, Brian is joking. The alternative if he is not, is that NASA is the joke. You don't have to try to explain the joke. There are no humans on the Hubble, and the time to take it up and drop it off is very, very short. Just a little bit longer than astronauts going to the moon will have to spend at that altitude. They won't be able to go to the moon if they are worried about the Orbiter dropping the Hubble off at a slightly higher altitude. Maybe it's sabotage, by some passive-aggressive mid level manager who didn't what to repair the Hubble. Snickering, "So there, you got your Hubble repair mission, but I'll have the last laugh as the fully functional Hubble spreads debris across Africa." lol |
