Samos 2
1961-001B
SAMOS 2 (Agena 2102), in January 1961, was one of the few successful missions, but its photos were disappointing. Orbit mass of SAMOS and Agena totalled 1915 kg. SAMOS 2 was part of the Program 101 series. The third Program 101 satellite, Agena 2103, was used mainly for engine static firings.
The satellite was another combined E-1/F-1 payload. The E-1 payload was mounted underneath F-1 and had a small field of view while F-1 obstructed it. F-1 was ejected to improve the field of view: this may have caused loss of contact with the vehicle.
