The second Jupiter to be fired under the operational control of NATO troops in the Combat Training Launch program was fired from AMR at 1919 hours and 06 seconds EST to a range of 1,516 nm. The missile was originally scheduled for firing on 3 August but was postponed because of problems with the fuel probe in the fuel start tank and the micro-switch on the fuel pumping lever arm which controls the fuel flow rate. All missions assigned to the missile and to the NATO training launch crew were successfully accomplished. References: 439 .
Mariners 6 and 7 were designed to fly over the equator and southern hemisphere of Mars. Mariner 7 encountered Mars on August 4, 1969. The two spacecraft returned a combined total of 143 approach pictures of the planet and 55 close-up pictures. The spacecraft also studied the Martian atmosphere and profiled its chemical composition. Closest approach to Mars for both spacecraft was approximately 3,550 kilometres.
2 TKS-VA capsules atop Proton. These were the same capsules launched as Cosmos 881/882 on December 15, 1976. The plan was that both capsules would orbit and return, demonstrating the reusability of the TKS VA design. The launch escape system pulled the top capsule away from the exploding Proton rocket and it was successfully recovered. The lower capsule was lost with the booster. References: 5 , 67 , 274 , 439 .
