Midas 5

 1962-010A


Midas flight 5 (Agena 1203) was orbited from Point Arguello on 1962 Apr 9. The Atlas roll control malfunctioned and the Atlas flew high and slow. The Agena burned correctly but instead of reaching the planned 160.91 min, 3422 x 3448 km x 87.04 deg orbit it ended up in a 153.04 min, 2796 x 3406 km x 87.00 deg orbit. The flight was classified at the time. A secondary battery failed after 7 orbits preventing further MIDAS operations; HEPDEX continued transmitting science data.
