  The smooth landing of the shuttle Discovery ended a flight that was successful in almost every respect but one:the dislodging of a big chunk of foam,like that doomed the columbia. This flight was supposed to vault the shuttle fleet back into space after a prolonged grounding for repairs. But given the repeat of the very problem that two years of retooling was supposed to resolve, the verdict is necessarily mixed. (61)Once again, the space agency has been forced to put off the flight until it can find a solution to the problem, and no one seems willing to guess how long that may take.

  The Discovery astronauts performed superbly during their two-week missing and the shuttle looked better than ever in some respects.(62)Space officials were justifiably happy that so much had gone well, despite daily worries over possible risks. The flight clear achieved its prime objectives.

  The astronauts transferred tons of cargo to the international space station, which has been limping along overhead with a reduced crew and limited supplies carried up on smaller Russian spacecraft.(63) They replaced a broken device, repaired another and carted away a load of rubbish that had been left on the station, showing the shuttle can bring full loads back down from space.

  This was the most scrutinized shuttle flight ever, with the vehicle undergoing clse inspect. While still in orbit. (64)New sensing and photographic equipment to look for potentially dangerous damage to the sensitive external skin proved valuable. A new backlip maneuver allowed station astronauts to photograph the shuttle’s underbelly, and an extra-long robotic arm enabled astronauts to photograph the shuttle’s underbelly, and an extra-long robotivc arm enabled astronauts to see parts of the shuttle that were previously out of sight.

  (65)The flood of images and openness in discussing its uncertainies about potential hazards sometimes made it appear that the shuttle was about to fall apart. In the end the damage was clearly tolerable. A much-touched spacewalk to repair the shuttle’s skin the first of its kind-moved an astronaut close enough to plug out some protroding material with his hand. Perliminary evidence indicates that Discovery has far fewer nicks and gouges than shuttles on previous flights, perhaps showing that improvenments to reduce the shedding of debris from the external fuel tank have had some success
