  Upper Atmospheric Research Satellite; deployed from STS-48 on 15 Sepetember 1991. It studied the depletion of the ozone layer, confirming that CFCs cause the `ozone hole', and improved models of upper atmosphere chemistry, including studies of methane in the Antarctic, sulphur dioxide from volcanoes, and global wind measurements. Some media hysteria surrounded its reentry on 24 September 2011, but it apparently came down unobserved in the Pacific Ocean east of Hawaii.

  Extreme Ultra-Violet Explorer; mapped galactic EUV sources. The Extreme Ultraviolet Explorer was switched off on February 2, 2001. NASA decided to terminate funding for the mission, even though the spacecraft was still operating well. The sky survey was completed in January 1993 and after that the EUVE was used by guest astronomers for observations of specific targets. The final observations were made on January 26, 2001. After end-of-life tests of the never-used backup high voltage supplies and checking the remaining battery capacity, EUVE was stabilized pointing away from the Sun and sent into safehold at 2359 GMT on January 31. The transmitters were commanded off on February 2.

  NASA's Magnetospheric Multiscale Mission was launched on Mar 13. The mission consists of four identical spacecraft, each with a mass of 1000 kg plus 400 kg of propellant. The spacecraft will fly in a tetrahedral formation some tens of kilometres apart to disentangle spatial and temporal fluctuations in the magnetospheric particle and field environment. They will deploy wire booms with a span of 112 metres to measure electric fields. Additional Details: here....
