AS-202
AS-202 (also referred to as SA-202) was the second unmanned, suborbital test flight of a production Block I Apollo Command/Service Module launched with the Saturn IB launch vehicle. It was launched on August 25, 1966 and was the first flight which included the spacecraft Guidance and Navigation Control system and fuel cells. The success of this flight enabled the Apollo program to judge the Block I spacecraft and Saturn IB ready to carry men into orbit on the next mission, AS-204.
==Objectives==
AS-202 was the third test flight of the Saturn IB, because a delay in the readiness of the Apollo spacecraft 011 pushed its launch past the July 1966 launch of AS-203. It was designed to test the rocket more than had been done on AS-201 by launching the rocket higher and having the flight lasting twice as long. It would also test the Command and Service Module (CSM-011) by having the engine fire four times during the flight.
The flight was also designed to test the heat shield by subjecting it to 260 megajoules per square meter. Over the course of the reentry it generated equivalent energy needed to power Los Angeles for over one minute in 1966.
CSM-011 was basically a production model capable of carrying a crew. However it lacked the crew couches and some displays that would be included on later missions for the astronauts. This was the first flight of the guidance and navigation system as well as the fuel cell electrical system.
