CAPE CANAVERAL (CBSMiami/AP) — SpaceX is trying for a second time to launch a cargo delivery to the International Space Station on Friday.
Liftoff is scheduled for 3:25 p.m. but stormy weather may force another delay.
NASA’s commercial supplier was foiled by a leaky rocket valve during Monday’s launch attempt. The valve has been replaced.
The unmanned Dragon cargo ship contains 2 1/2 tons of station supplies, including material for urgent computer repairs. A backup computer failed outside the space station last Friday. Astronauts will conduct a spacewalk to replace the computer in the next few days.
NASA says the material on the Dragon is desirable for the repair job, but not essential. Much-needed food is also aboard, along with a new spacesuit and spacesuit replacement parts.
