NASA Satellite Un-stranded

Posted by michael on from the get-out-and-push dept.

Ronnie Coote writes "In March, a previous article mentioned that NASA's latest Tracking and Data Relay Satellite (used for communications between Shuttle, Space Station, ground, etc) had been stranded in a low orbit due to fuel leaking from its tanks. Well, thanks to the hard work of Boeing and NASA boffins, it's now reached geostationary orbit and "expected to fulfill its contractually required 15-year service life". More details from Boeing."

  1. RTF Press Release, damn it! by Observer · · Score: 5, Informative
    The problem was not a leaking fuel tank. The Boeing press release linked in the /. story (it's only a few hundred words, for pity's sake) says clearly that the problem was that the pressurant (that is, the thing that pushes the fuel out of the tank to the motor) didn't get to the tank, because of a blockage in a valve.

    But all kudos to the engineers from Boeing and NASA who worked out what the problem was - quite possibly from fairly subtle clues in the telemetry information or some very careful trial and error experiments - and how to get around it and coax the satellite up to its intended orbit.
