Weather clears for SpaceX launch from Cape Canaveral



CAPE CANAVERAL. Fla. - A SpaceX rocket was launched from the Cape Canaveral Air Force Station with a critical delivery to the International Space Station.
Liftoff happened on time at 3:25 p.m. Friday. Officials had been concerned that stormy weather might  force another delay but the clouds parted well before the launch.
NASA's commercial supplier was foiled by a leaky rocket valve during Monday's launch attempt. The valve has since been replaced.
The unmanned Falcon 9 Dragon rocket 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 said 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.
