Manned seven crew. Deployed ERBS; performed high resolution Earth imagery. Payloads: Earth Radiation Budget Satellite (ERBS) deployment, Office of Space and Terrestrial Applications (OSTA)-3 experiments, Large Format Camera (LFC). First use of Orbital Refueling System (ORS) with extravehicular activity (EVA) astronauts, IMAX camera. In response to the American Strategic Defence Initiative and continued military use of the shuttle, the Soviet Union fired a 'warning shot' from the Terra-3 laser complex at Sary Shagan. The facility tracked Challenger with a low power laser on 10 October 1984. This caused malfunctions to on-board equipment and discomfort / temporary blinding of the crew, leading to a US diplomatic protest. Additional Details: STS-41-G. References: 1 , 2 , 5 , 6 , 7 , 33 .
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.

The Space Shuttle orbiter Enterprise arrived at Vandenberg AFB for a series of facility verification tests. References: 88 .
By the end of 1984 the static and dynamic test models of the station had been completed. The ground test model of the station was delivered in December 1984. The use of this full-fidelity test article, an approach taken on the Almaz program, was new to the civilian DOS project.
Replaced Molniya 1-55. Operation of the long-range telephone and telegraph radio communications system in the USSR; transmission of USSR Central Television programmes to stations in the Orbita network. References: 1 , 2 , 5 , 6 .
Investigations of the planet Venus and Halley's Comet. The APV-V plasma antenna did not deploy until the first mid-course correction burn. Deployed lander and balloon at Venus on June 19 1985. Rendezvoused with comet Halley on March 6, 1986. Fitted with scientific apparatus and equipment built in the USSR, Austria, Bulgaria, Hungary, German Democratic Republic, Poland, France, Federal Republic of Germany and C zechoslovakia.

Investigations of the planet Venus and Halley's Comet. The APV-V plasma antenna did not deploy until the first mid-course correction burn. Deployed lander and balloon at Venus on June 14, 1985. The surface experiments of the lander failed to send back data because they were inadvertently switched on at an altitude of 20 km. Apparently high winds activated a G-force sensor that was to automatically switch on the surface package after the jolt of touchdown. The bus continued in heliocentric orbit and rendezvoused with comet Halley on March 9, 1986. The images of the comet were nearly lost when a television sensor failed shortly before the flyby. A back-up sensor was activated just in time. Fitted with scientific apparatus and equipment built in the USSR, Austria, Bulgaria, Hungary, German Democratic Republic, Poland, France, Federal Republic of Germany and C zechoslovakia.

Maximum speed 45 kph. Time 5 minutes. Thereafter to PRSO test stand for full-scale equipment tests; then to PDST pilot-dynamics test stand for further tests. References: 81 .
