NASA Satellite Stranded

Once there, one of its roles would be to route data between the ISS, other satellites and the ground as aprt of the TDRS (Tracking and Data Relay Satellite) project. However a fuel tank is leaking and it cannot reach its orbit. One suggestion is that it maneuver itself into an orbit where the shuttle can reach and rescue it - to repair it and send it on its way, or bring it home to be launched again."

    This is the story of the successful rescue of an Intelsat after it failed to seperate from its rocket and got stuck in a low orbit. It took 6 tries over 3 days for the shuttle crew to catch it.

    The TDRS satellite has a similar mass to the Intelsat

  2. Shuttle rescue unlikely by Jonathan+McDowell · · Score: 3, Informative
    As I pointed out in my newsletter JSR on Friday (before the BBC story, I note :-)) it's unlikely that they will try a Shuttle rescue because it would take more fuel to get down to a Shuttle orbit than to get up to GEO, given where it is now. All the previous rescues involved satellites in much lower orbit. Oh, and as a side note to the poster who commented on the post-Challenger regulations, it's only liquid hydrogen that the Shuttle won't deal with in the payload bay, there have been plenty of payloads since then which have had hydrazine and nitrogen tetroxide on board, which is what the BSS-601 satellites like TDRS-I carry.

    I draw slashdot's attention to the fact that the story was originally broken by Keith Cowing's excellent NASA Watch web page. I expect that they will get the bird to GEO, although Space Command doesn't seem to have issued any new orbital data for it in several days.

    Well, NASA has 3 choices Re-entry, Retrieve and Relauch, or Repair.

    I fear this post has missed an essential point -- as the article makes clear, this isn't NASA's problem, it's Boeing's problem. NASA doesn't pay for the thing and doesn't own it until it's in the right orbit.
