Why not bring the Hubble back to Earth?
Yes, it is like all missions, dangerous, but it would be good to have
one of the most productive pieces of scientific gear back, in a museum once it is decommissioned rather than burned up and dumped into the Pacific ocean. It is certainly a far more important (for history) task than sending countless missions to the money-sucking, "results not-oriented" ISS. |

But getting it back would be really expensive, it would be dangerous, and would provide nothing but sentimental value.

Yes, bringing it back to Earth is little better than letting it burn up on re-entry. Now, if a small rocket booster could be dispatched to it, to bring it to dock with the ISS, then it would at least still be in orbit, and later it could be put to good use again. John Savard |

Ya. picture that... the ISS with it's own observatory.

While the Hubble was launched by the shuttle and fits in the bay, the dynamic loads on re-entry are undoubtedly different than launch loads. I'd be very surprised if the shuttle could safely re-enter and land with the Hubble aboard. Anyway, if the intention is to preserve the Hubble as a science museum, it's current environment is far superior. |

I'd be very surprised if the shuttle could safely re-enter and land with the Hubble aboard. That was my first thought, as well. A little research revealed that while the payload would be above the preferred landing weight, it isn't above the design limit. The shuttle never takes more up than it can land with, because it needs to be able to abort in an emergency. _________________________________________________ Chris L Peterson Cloudbait Observatory http://www.cloudbait.com |

I think it will basically have run out of things to do and any new scope would be designed differently to allow robotic maintenance. There is presently a NASA competition running to redesign astronauts gloves to permit better fine motor control. Humans are not that great when working in a clumsy pressure suit.

It's true that the Hubble is heavier than the LDEF, for example, but if that was an issue, Spacelab would have been a problem as well, I would think. John Savard |

Ah.. no With no maintenance burnup will occur automatically because of atmospheric drag. That even goes for the ISS, which gets an occasional boost from a visiting craft, so even keeping hubble at the ISS will need occasional fuel. |
