...Still, gnawing doubts remained. Despite exhaustive ground testing of the new and modified shuttle parts, none had been tried in the harsh environment of a launch, or in orbit or re-entry. Moreover, some of them are among the more than 1,500 "criticality 1" parts -- that is, items without backup whose failure could end the mission, perhaps catastrophically...
NASA's new manner was in marked contrast to its bold, often arrogant and occasionally careless approach in pre-Challenger days. NASA initially promoted the shuttle as a routine "space truck," an efficient, economical transport vehicle capable of lofting any payload -- commercial, scientific or military -- into orbit. Washington succumbed to that pitch, allowing NASA to decree ! that expendable rockets such as the Delta, Atlas and Titan be phased out in favor of the shuttle...
...extending our view to the edges of the universe, fell years behind schedule. Crucial deadlines were missed for shuttle launches of the planetary probes Magellan, designed to map the surface of Venus, Galileo, to survey Jupiter and its moons, and Ulysses, to conduct solar studies from a polar orbit around...
...result of its difficulties, NASA has lost potential commercial clients to the European Space Agency, which will put payloads into orbit aboard unmanned Ariane rockets at bargain prices (cost: about $40 million per payload). Even more galling was last month's decision by the Reagan Administration to allow China to launch two U.S. communications satellites, a move that stunned the fledgling U.S. commercial rocket industry. "That hurt, and hurt hard," says an executive of one U.S. firm. "We wanted those birds...
NASA's long ordeal is nearly over. The space shuttle has again shown it can blast astronauts into orbit on biblical smoke pillars. There is much to admire in the sight of the astronauts circling the earth in their splendid reusable spaceship, but there is also something disappointing. For the past two decades the American space program has been going mainly in circles, riding a splendid shuttle to nowhere. Once upon a time NASA launched men to the moon and sent robots across the solar system; there was even brave talk of expeditions to Mars. Now that the nightmare...
