Associated space launch
The Transit-O series of satellites that closely followed the design of Transit 5C-1 were also called “Oscars” (Oscar is the phonetic alphabet for “O”, i. e., operational). They were also called NNS (Navy Navigation Satellite) or shortened NavSat.
OSCAR 24 was lifted into orbit during the mission ‘Scout G-1 | Transit-O 24,30’, on board a Scout G-1 space rocket.
The launch took place on Aug. 3, 1985, 3:31 a.m. from Space Launch Complex 5.
