Gregory Jarvis was cremated, and his ashes scattered in the Pacific Ocean. Unidentified crew remains were buried communally at the Space Shuttle "Challenger" Memorial in Arlington on May 20, 1986. As a result of the disaster, several National Reconnaissance Office (NRO) satellites that only the shuttle could launch were grounded because of the accident. This is a dilemma NRO had feared since the 1970s when the shuttle was designated as the United States' primary

The Shuttle was monitored throughout its ascent for short range tracking (10 seconds before liftoff through 57 seconds after), medium range (7 seconds before liftoff through 110 seconds after) and long range (7 seconds before liftoff through 165 seconds after). Short range cameras included 22 16mm cameras on the Mobile Launch Platform and 8 16mm on the Fixed Service Structure,
