NASA representatives met with the media on Monday and announced that the space shuttle would begin operations again some time between March 11 and April 6. Several safety changes are going to be made before the first shuttle, Atlantis, launches to visit the International Space Station: the bipod ramp (which shed foam on the Columbia launch) will be redesigned, and launch windows will only be in the day so cameras can track the launch. Perhaps the biggest changes, however, will come from NASA’s attempts to change its culture to improve safety. “We will be safety driven, not schedule driven.”
