Launch from Cape Canaveral (
KSC);
landing on Edwards
AFB.
The launch was originally scheduled for
November 20, 1989, but was delayed because of suspect integrated electronics
assemblies which control ignition and separation of the Shuttle's solid rocket
boosters.
S. David
Griggs, the originally scheduled pilot for this mission, died
in a plane crash 5 months prior to the shuttle launch. He was replaced by John
Blaha.
This flight was the fifth mission dedicated to
the Department of Defense. Mail goal was to deploy the reconnaissance satellite
"Big Ear" (Magnum 2; USA-48), a secret Magnum ELINT (ELectronic INTtelligence)
satellite. Frederick
Gregory became the first afro-american spacecraft commander.
The landing was postponed for a day because of strong winds at the
landing site.
