NASA engineers expect to spend most of Wednesday trying to figure out whether a couple of late-breaking glitches are a threat to Thursday night's scheduled space shuttle launch.
Discovery, which is slated to take off on a mission to rewire the international space station's electrical system, experienced a brief power surge yesterday. Early tests show no damage.
And NASA engineers also have to resolve potential problems with a glue that helps seal rocket boosters. NASA says the glue might not be as strong as it should be, but it's not the main component that keeps hot gas from escaping.
Launch managers say it's too early to tell if the problems will postpone what's supposed to be the first nighttime launch in four years. Since Columbia's ill-fated mission, NASA had required day launches to keep an eye on possible debris coming off the spacecraft's external fuel tank.
