Associated space launch
The KH-4 (Keyhole-4) was fourth version in the Corona-program to build an optical reconnaissance satellite. KH-4 24 also carried the RM 5 radiometer payload for background measurements for the MIDAS program.
TIROS 8 was lifted into orbit during the mission ‘Thor SLV-2A Agena D | KH-4 26’, on board a Thor SLV-2A Agena D space rocket.
The launch took place on Dec. 21, 1963, 9:45 p.m. from Space Launch Complex 2W.
