NASA grounds shuttle fleet - Yahoo! News

It looks like NASA is going to ground the space shuttle fleet, following revelations that pieces of fuel-tank insulation broke off again. This is a good-news / bad-news story. The bad news, of course, is that the insulation did not perform as expected. It had been hoped, apparently, that only small flakes of insulation would come off -- not enough to damage the shuttle. The good news is that NASA is taking this seriously this time. Let's all pray that no damage has been done to Discovery and that the 7 astronauts can get home safely.
