Most of the space garbage consists of nonfunctioning satellites and space probes launched from earth. There is also fragmentary junk, resulting from mid-space collisions between spacecraft and meteorites. Astronauts have dumped sewage, food containers and spent oxygen cylinders overboard. On rare occasions, space walkers have accidentally dropped objects in space. Astronaut Ed White lost a shiny white glove during the Gemini 4 flight in 1965. George ("Pinky") Nelson fumbled away two tiny screws while repairing the Solar Maximum Mission satellite during the shuttle flight last month...
...have fallen from orbit, but the number that survived the atmospheric plunge to hit the earth is unknown. Shards have landed on more than a dozen nations, including Zambia, Finland and Nepal. As early as 1961, Premier Fidel Castro indignantly charged that a re-entering chunk of a U.S. spacecraft had struck and killed a Cuban cow. A year later, a 21-lb. metal cylinder landed at the intersection of North 8th and Park streets in Manitowoc, Wis. The debris was later identified by the U.S. Air Force as a fragment of Soviet Sputnik 4, launched two years earlier...
...walk in space to retrieve the ailing Solar Maximum Mission satellite (Solar Max). Sent aloft to monitor the sun's activity, Max broke down three years ago, after only ten months in orbit. Challenger's mission last week was to stop the rotation of Max, use the spacecraft's 50-ft. remote-controlled arm to lift the satellite into the ship's cargo bay, and set it back in orbit after repairs were made...
...space until it is hauled in by a shuttle vehicle next February. It will gather data on how such materials as shrimp eggs, tomato seeds and plastics fare in space. It will also take samples of interstellar gas to learn more about the evolution of the universe. Inside the spacecraft another, more active scientific venture was also going on. In a test devised by a Tennessee college student, more than 3,000 honeybees were sent aloft in a special container to determine the effects of weightlessness on the construction of hives...
NASA selected the Harvard Center to assist in designing the spacecraft primarily because of its experience in similar projects, namely designing and operating the Einstein observatory, Newton said...
