NOAA-B (somehow should have been NOAA-7) was a failed mission and a destroyed satellite that was launched on May 29, 1980. It became space debris. It was considered a failure because of its very elliptical orbit.

Failure

Due to a fuel leak, the first stage main engine could only achieve 80% thrust, and therefore the first stage burn was extended by 50 seconds. Due to the inability of the first stage to relay this to the upper stage, 375 seconds into the flight the rocket attempted to jettison the first stage while it was still burning. Recontact between the stages led to the second stage being unable to manoeuvre to the necessary attitude for its burn, resulting in the vehicle achieving a uselessly elliptical orbit. The mision was considered a total loss. [1]
