STS-46 (Atlantis)

 1992-049A


The EURECA deploy was delayed one day because of intermittent data problems. After deploy, Atlantis separated to 290m and remained there an extra orbit. Five hours after the 12m boom was extended, the subsatellite was released for the first flyaway. However, the release was aborted after only 10 cm of tether was deployed, and after 13 minutes the satellite was reeled back in to the docking clamp. On the next orbit, the flyaway began again. This time the tether snagged at a distance of 220m, on a bolt in the deployer mechanism.
