STS-73 STS-72

STS-74 ( english S pace T ransportation S ystem) is a mission designation for the US Space Shuttle Atlantis ( OV -104) of NASA . The launch took place on November 12, 1995. It was the 73rd space shuttle mission, the 15th flight of the space shuttle Atlantis, the fourth flight as part of the Shuttle Mir program and the second coupling of the US space shuttle to the space station me .

Mission description

With the Atlantis developed in Russia and built coupling module came SDM to the Mir space station . It was lifted out of the cargo bay on the second day of flight and placed on the Atlantis' coupling adapter. A new camera system was used at the tip of the manipulator arm to facilitate access (OSVS = Orbiter Space Vision System ). The coupling to the space station took place on the fourth day of the flight.

Several scientific studies were carried out during the joint flight phase. The stability of the complex, which weighs more than 200 tons, was examined. In particular, the NASA scientists were interested in the movements of the solar cell boom when the engine ignites or changes in position with the help of gyro systems (PASDE experiment = Photogrammetric Appendage Structural Dynamics Experiment ). For the first time, the interaction of the space station with the atoms of the thin residual atmosphere (GLO / GPP) was researched. Noise measurements were made in different parts of the space station ( Mir Audible Noise Measurement ). In this way, particular sources of noise should be detected. These findings were taken into account in the design of the International Space Station .

The central task of the mission was also the transport of water, supplies, new equipment and experiments to the space station and the return of experimental samples and commercially produced semiconductor and protein crystals to Earth. In particular, blood, saliva, urine, water and air samples were then examined on earth. They were the result of experiments on adapting the body to weightlessness, on physiological changes such as muscle or calcium depletion, and on the environmental conditions in the ward.

During the flight, recordings were made with an IMAX film camera. The 65 mm special film enables particularly high-resolution images. These were not only evaluated by NASA for technical purposes, but also enchanted millions of interested viewers in special cinemas. The numerous contacts between the astronauts and radio amateurs around the world were just as effective . Conversations with students from American educational institutions (experiment SAREX ) were particularly popular .

After a successful flight, the Atlantis landed in Cape Canaveral ( Kennedy Space Center ).
