SpaceX is shooting for another launch attempt Friday to the International Space Station.
NASA confirmed the launch date Wednesday, two days after a last-minute rocket leak delayed the delivery mission. Stormy weather, however, is forecast for Friday. Saturday is the backup launch date.
Mission Control has rescheduled urgent spacewalking repairs because of the new launch time. The two U.S. astronauts had been aiming for a Tuesday spacewalk to replace a backup computer that failed late last week. If SpaceX launches Friday from Cape Canaveral, the spacewalk will move to next Wednesday. A Saturday launch would bump the spacewalk up to Easter Sunday.
The Dragon contains more than 2 tons of supplies, including material that would prove useful for the repair, but it's not essential.
