STS -69 (English Space Transportation System) is a mission name for the U.S. Space Shuttle Endeavour ( OV -105 ) from NASA. The launch took place on 7 September 1995. It was the 71st Space Shuttle mission and the ninth flight of the Space Shuttle Endeavour.

- Duration: 6 hours, 46 minutes
During the eleven-day mission, the second several-day free flight of the Wake Shield Facility ( WSF ) was performed, a saucer- shaped satellite that flies free in addition to the Shuttle. Here, an experiment was conducted in which, in the WSF in perfect vacuum a very thin film was formed. In addition, the crew continued the astronomical satellite SPARTAN 201 and caught him again, led a 6-hour spacewalk by the testing of assembly techniques for the International Space Station and tested thermal improvements to the space suits used.
Free-floating SPARTAN 201 completed its third flight during this mission. The association of the sun and produced by her current of charged particles was investigated here ( solar wind ). In particular, the outer atmosphere of the sun and the output of the solar wind has been investigated by this.
STS -69 also introduced the International Extreme Ultraviolet Hitchhiker ( IEH -1) to measure the first of five planned flights to the flow strength of the coming of the sun extreme ultraviolet (EUV ) and to follow its course, and the EUV emission of the plasma torus around Jupiter, which emanates from its moon Io.
In addition, the combined Capillary Pumped Loop-2/Gas Bridge Assembly ( CAPL-2/GBA ) was experiment on board. It demonstrated a cooling system in weightlessness, which was intended for the Earth Observing System Program. The Thermal Energy Storage -2 ( TES -2) experiment focused on advanced energy technologies. In addition, several Get Away Special ( GAS ) experiments were the different areas such as the interaction of the position of the spacecraft with orbit control system, fluid-filled bars for use as a shock absorber or the effects of a glowing fire investigated under microgravity conditions on board. Behavior and to make cavities in lithium fluoride and calcium fluoride has been researched salts that can store thermal energy. The data of this experiment were used by the project TESSIM.
Another payload on board was the Electrolysis Performance Improvement Concept Study ( EPICS ), which also was associated with the ISS in conjunction. The replenishment of oxygen and hydrogen by electrolysis of water will play a major role in future space missions. The production of oxygen on the space station could reduce the annual consumption of supply goods 5,400 kg.
Other payloads on board were:
- National Institutes of Health -Cells -4 ( NIH - C4 ), which examined the bone loss during space flight
- Biological Research in Canister -6 (BRIC -6 ) investigated the gravitational detection of mammalian cells
- ( CMIX -4) was a commercial experiment that investigated the influence of gravity on cells, in particular the emergence of neuro-muscular disorders
- Commercial Generic Bioprocessing Apparatus -7 ( CGBA -7 ), another commercial experiment that collected data that were used for the pharmaceutical, biomedical, biotechnology, agriculture and the environment in general.
