27 Dec. 1966

Approved phase B procurement plan for capsule systems distributed within NASA. Not released publicly until 17 Jan.1967.

27 Jan. 1967

Project Approval Document for phase B signed. MSFC was assigned management responsibility for both Voyager spacecraft and Saturn V launch vehicle. JPL and Langley to share responsibility for lander. Apollo 204 fire killed Virgil I. Grissom, Edward H. White II, and Roger B. Chaffee.

31 Jan. 1967
