Launch at Night

摘要

The successful mission of the Space Shuttle At-lantis Sept. 9-21 showed that the safeguards put in place to prevent the kind of accident that destroyed the Columbia orbiter are working well enough to let NASA go back to launching shuttles at night when necessary. Shuttle managers took an initial step in that direction late Sept. 28. When the agency's Program Requirements Change Board meets Oct. 5 at the Johnson Space Center in Houston they should formalize the change.
