The Apollo Command Module (CM), joined with its Service Module (SM), acted as the "mothership" for lunar missions from 1968 to 1972. It flew an Earth orbit test flight (Apollo 7), the first manned lunar orbit mission (Apollo 8), two Lunar Module (LM) test flights (Apollo 9 and 10), and several lunar landing missions (Apollo 11, 12, 14, 15, 16, and 17). The spacecraft also supported Skylab (Skylab 2, 3, and 4) and the Apollo-Soyuz Test Project (ASTP).

The first CM design configuration for Earth orbit test flights was known as Block 1 and was intended to fly the Apollo 1 mission in early 1967. During a launch pad test on January 27, 1967, a fire in the CM claimed the lives of the Apollo 1 crew: astronauts Gus Grissom, Ed White, and Roger Chaffee. The subsequent accident investigation identified hundreds of engineering changes to be incorporated into the Block 2 CM for lunar missions, in which all subsequent Apollo missions were flown.

The Museum's Apollo Command Module, known as CM 007 and CM 007A, is the first production-line capsule delivered to NASA for testing and training. It was originally identical to the Apollo 1 Block 1 spacecraft 012, which experienced the fatal fire. After impact and acoustic testing at the North American plant in Downey, California, CM 007 was delivered to NASA's Manned Spaceflight Center in Houston, Texas on April 18, 1966. It was used for water impact and flotation tests in the Gulf of Mexico. In 1967, CM 007 was sent back to North American for modification to Block II configuration. It was re-designated CM 007A and returned to Houston for qualification tests of the redesigned hatch and other changes mandated by the Apollo 1 accident review board. The module was also used for a 48-hour open water test, crewed by astronauts James A. Lovell, Jr., Stuart A. Roosa, and Charles M. Duke, Jr. in April 1968.

In 1971, CM 007A was transported to Eglin Air Force Base, Florida, for extreme cold testing in support of the Skylab program. It was then stored in Houston until 1988, when it was restored for the Museum by the Kansas Cosmosphere and Space Center.
