...ROBINSON IN ANY DANGER DURING HIS SPACEWALK? No spacewalk is remotely risk-free. Space suits could be damaged by tools; equipment could malfunction; there?s even the risk of being struck by mictometeors or bits of space debris. But NASA astronauts have been venturing outside of their ships for more than four decades and all of them have come safely back inside...
...NASA insists that none of the chips present a danger, but in the days leading up to Discovery's planned Aug. 7 return, engineers--to say nothing of the astronauts' families--will be anxiously watching for any change in that assessment. If the shuttle were deemed unsafe to fly, the crew could take refuge in the space station, waiting out the five weeks it would take to roll out and gas up sister ship Atlantis for a rescue mission. But Wayne Hale, deputy shuttle manager, dismisses that scenario as "remote...
...surprises remain at the end, including a new enemy or two, which are mildly unexpected, though mired in pitiful dialogue and unintentionally comical scenes. Certainly Cohen was not aiming for greatness, but he couldn’t even break the summer action sound barrier. A few careers are in danger of crash landing along with “Stealth”; we’ll have to wait and see if someone makes it out alive...
...although the fact that NASA has stopped future flights also signals the much tighter safety standards that are now in place. Shuttles have been shedding tiles and foam for years, but luck and careful maintenance prevented tragedies. Then Columbia happened. Since then, NASA has narrowed the aperture of danger it is willing to tolerate. The current shuttle, by comparison to some of the previous missions, is remarkably clean despite the foam that fell off. In that respect, it shows that the work of the past two years has produced a lot of results. It's about as clean...
...inches long, adjacent to the wheel-well where the front landing gear is stored. If superheated gases stream into that open space during reentry, it can create a kind of vapor bomb inside the ship. But the photography suggests the divot isn't deep enough to cause that danger. So far, it looks like they'll be fine...
