At Santa Susana, Calif., a complete liquid-rocket engine assembly (Navaho) having a thrust in excess of 200,000 pounds was fired for the first time. References: 17 , 278 .

The fourth Jupiter was fired from AMR at 1602 hours EST over IRBM range and was the second successful flight of the series. The range error was 27.5 nm with a 36.5 nm lateral error. Range was predicted for 146 nm. LOX was cut off at 170 seconds. All flight missions were fulfilled satisfactorily. Separation occurred 5 seconds after burnout, as programmed, This was the first test of separation of body from thrust unit. References: 439 .

NASA selected Vitro Engineering Co. for negotiation of a design contract for an engine maintenance and disassembly building, one of the facilities to be a part of the National Nuclear Rocket Development Center. References: 18 .

The Little Joe II qualification test vehicle was launched from White Sands Missile Range, N Mexico. Its objectives were to prove the Little Joe's capability as an Apollo spacecraft test vehicle and to determine base pressures and heating on the missile. These aims were achieved. The lone failure was a malfunction in the destruct system. References: 16 .

Returned 27,000 cloud cover images. The spacecraft carried an advanced vidicon camera system for recording and storing remote cloudcover pictures, an automatic picture transmission camera for providing real-time cloud cover pictures, and a high-resolution infrared radiometer to complement the daytime TV coverage and to measure nighttime radiative temperatures of cloud tops and surface terrain. A short second-stage burn resulted in an unplanned eccentric orbit. Otherwise, the spacecraft and its experiments operated successfully until September 22, 1964. The solar paddles became locked in position, resulting in inadequate electrical power to continue operations. References: 1 , 2 , 5 , 6 .

MSFC issued a modification to an existing contract with McDonnell Douglas for Skylab Program work. The modification would pay for the conversion of the original OWS to be launched by a Saturn IB booster to a completely outfitted Workshop to be launched by a Saturn V. Originally the plan was to launch the second stage (S IVB) of a Saturn IB into Earth orbit. The S-IVB would be filled with fuel so that it could propel itself into orbit. Astronauts launched by a second Saturn IB would then rendezvous with the empty stage and convert it into living and working quarters. A decision was made 21 May 1969 to outfit an S-IVB on the ground and launch it ready for use on a Saturn V.
