...Caribou C-7 he flew on combat missions in Viet Nam. Scobee entered astronaut training in 1978 and helped fly the 747 that carried the shuttle spacecraft between ground stations. As pilot of Challenger in 1984, he guided the spacecraft so that fellow crew members could retrieve a broken Solar Max satellite, which was repaired on board and later placed back into orbit. At an in-flight press conference, Scobee and the mission's four other astronauts showed up in T shirts that read ACE SATELLITE REPAIR...
...able to use them somehow, to do something that required a concerted team effort and, finally, a great individual effort." She also took up racquetball and weight training. On her first shuttle flight, aboard Discovery in 1984, Mission Specialist Resnik operated the spacecraft's remote-control arm and performed solar-power experiments with a 102-ft.-high solar sail. She also provided one of the most memorable images in space- program history when television cameras aboard Discovery captured her--in polo shirt and shorts--concentrating on her tasks while her long, curly dark brown locks wafted above her head...
Data recently radioed back by Voyager 2 have given scientists new photographs of the five major moons of Uranus. The moon Miranda emerged as an icy world unlike any other ever seen in the solar system...
...tails, not always visually distinct, both extending millions of miles by the time the comet has moved close to the sun. They now know that the yellowish, often curved tail is composed of dust particles released during sublimation and swept away from the sun by the pressure of solar radiation. Sunlight reflecting off the tail produces the fiery effect. The second, bluish appendage is called the plasma or ion tail. It is formed when gases from the comet's nucleus become charged by solar radiation and then react with the solar wind, which is a constant stream of charged particles...
...Oort Cloud, explains Berkeley's Spinrad, would consist of at least a trillion "dull blocks of ice," ranging from a few inches to a few miles in diameter. Out in that velvet blackness of space, where temperatures approach absolute zero, the snowballs remain unchanged, well beyond the effects of solar radiation, meteorite impacts, volcanic activity, atmosphere and other phenomena that have gradually changed the inner members of the solar system. Every once in a while, however, a passing star gives the cloud a gravitational jiggle, releasing hundreds of these fragments. Most of them are sent outward into interstellar space...
