International Ultraviolet Explorer shuts down
Launched in 1978 as a joint venture between NASA and ESA, the unmanned International Ultraviolet Explorer is commanded to exhaust its remaining fuel and cease all contact with Earth. Though its detectors and other instruments are still functioning well after 18 years in orbit, its stabilization gyros have failed one by one until the satellite is unable to be aimed at deep space targets with any accuracy. IUE remains powered down, adrift in a geosynchronous orbit.

The fourth episode of the science fiction series The Cape premieres in syndication in North America, starring Corbin Bernsen (L.A. Law) and Adam Baldwin, and focusing on a fictionalized version of NASA’s shuttle program. 
A long-standing mystery of one of the moons of Jupiter is solved, opening many more questions. Data gathered by the Galileo unmanned orbiter reveals that a previously unidentifiable substance on Europa’s surface is sulfuric acid, a compound used as battery acid on Earth. Scientists quickly split into two camps on the origins of the acid: it may be welling up from inside Europa, or it may be volcanic material ejected from Io and then deposited on Europa as the moons’ orbits occasionally bring them into conjunction. Though the presence of sulfuric acid initially dashes hopes of finding life on Europa, the possibility is not completely ruled out by this finding.
Part of the 21st full-time crew of the International Space Station lifts off from Russia’s Baikonur Cosmodrome aboard Soyuz TMA-16. Maksim Surayev and Jeffrey Williams take up residence on the ISS for 168 days, becoming part of the Expedition 21 crew. Joining them for the flight to the ISS is Canadian space tourist and Cirque de Soleil CEO Guy Laliberté, who visits the station for ten days before returning to Earth aboard Soyuz TMA-14 with members of the Expedition 19/20 crew. As with other space tourists before him, he pays for his own Soyuz seat and space training, but the impending retirement of the space shuttle fleet puts an end to Soyuz space tourism for several years after this flight.
