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.
CALSPHERE 2 was lifted into orbit during the mission ‘Thor DM-21 Ablestar | Transit-O 1’, on board a Thor DM-21 Ablestar space rocket.
The launch took place on Oct. 6, 1964, 5:04 p.m. from Space Launch Complex 2W.
