1993-058A
STS-51 suffered an RSLS abort on Aug 12, but successfully took off a month later on a mission to deploy the ACTS communications satellite and fly the ORFEUS-SPAS experiment. After a one-orbit delay due to comm problems ACTS/TOS was ejected from its cradle. Because of a command error, the explosive separation tube was more powerful than intended and left sharp edges and debris on the support cradle and in the payload bay to the rear of bay 10.
