This was the Soviet Union's first attempt at a planetary probe. Mars probe intended to photograph Mars on a flyby trajectory. The possible cause lay in resonance vibrations of upper stages during Stage 2 burning, which led to break of contact in the command potentiometer of the gyrohorizon. As a result a pitch control malfunctioned and the launcher began to veer off the desired ascent profile. On exceeding 7 degrees of veering in pitch, the control system failed. The upper stage with the payload reached an altitude of 120 km before burning up on re-entry into the atmosphere above East Siberia. References: 5 , 64 , 65 , 118 , 296 .
NASA Argo D-4 rocket was launched from Wallops, reaching an altitude of 585 miles and landing 817 miles out in the Atlantic, to gather data on the density of electrically charged helium atoms in the upper atmosphere. References: 18 .
Major milestones were reached for extending astronauts' staytime on the moon and increasing their mobility for the Apollo 16-20 missions. Modifications in the A7L spacesuit incorporating improved waist mobility were authorized, and letter contract authority for the portable life support system secondary life support system was approved.

Seasat was the first satellite designed for remote sensing of the Earth's oceans with synthetic aperture radar (SAR). The mission ended on October 10, 1978 due to a failure of the vehicle's electric power system. The suspicion exists that the satellite was intentionally shut off because the quality and nature of the results obtained alarmed the Pentagon.
After the American decision was taken into 1983 to initiate the 'Star Wars' strategic defence initiative program, Minister of Defence Ustinov requested that the Americans be challenged. As a 'warning shot' the Terra-3 complex was used to track the space shuttle Challenger with a low power laser. This caused malfunctions to on-board equipment and temporary blinding of the crew, leading to a US diplomatic protest.
Second successful Zenit-3SL flight from the Odyssey launch platform in the Pacific Ocean at 154 deg W, 0 deg N. First flight to carry a commercial payload. The satellite used its R-4D apogee engine to enter geostationary orbit at 81.6 deg W. Finally stationed at 101 deg W.
