2tv1_v_c_o_AKP (707-16, F-429-02)

Interior view of the 2TV-1 Command Module, ca. 1968. The Apollo 2TV-1 "mission" involved the crew of Joe Kerwin, Vance Brand, and Joe Engle staying in the CSM test spacecraft (2TV-1) for 177 hours while the spacecraft was in a large vacuum chamber in Houston. A similar test (LTA-8) was run on the LM, with James Irwin and John Bull. The purpose of the tests was to verify the spacecraft were capable of operating in the vacuum of space, under the temperatures and lighting conditions that would be experienced during an Apollo space flight. Note that the center couch has been removed in order to provide some freedom of movement not otherwise possible under earth's onerous gravity.
