Saturn 1 - COSPAR 1965-009
Status: Retired 1966. First Launch: 1966-07-05. Last Launch: 1966-08-25. Number: 2 . Thrust: 7,290.00 kN (1,638,850 lbf). Gross mass: 587,300 kg (1,294,700 lb). Height: 68.10 m (223.40 ft). Diameter: 6.53 m (21.42 ft). Apogee: 250 km (150 mi).
First orbital test Saturn IB; no spacecraft. AS-203 lifted off from Launch Complex 37, Eastern Test Range, at 10:53 a.m. EDT in the second of three Apollo-Saturn missions scheduled before manned flight in the Apollo program. All objectives - to acquire flight data on the S-IVB stage and instrument unit - were achieved.
The uprated Saturn I - consisting of an S-IB stage, S-IVB stage, and an instrument unit - boosted an unmanned payload into an original orbit of 185 by 189 kilometers. The inboard engine cutoff of the first stage occurred after 2 minutes 18 seconds of flight and the outboard engine cutoff was 4 seconds later. The S-IVB engine burned 4 minutes 50 seconds. No recovery was planned and the payload was expected to enter the earth's atmosphere after about four days.
Spacecraft 011 was essentially a Block I spacecraft with the following exceptions: couches, crew equipment, and the cabin postlanding ventilation were omitted; and three auxiliary batteries, a mission control programmer, four cameras, and flight qualification instrumentation were added.
Of six primary test objectives assigned to the mission, the objectives for the environmental control, electrical power, and communications subsystems were not completely satisfied. All other spacecraft test objectives were successfully accomplished.
