CAPE CANAVERAL, Fla. - SpaceX has launched from Cape Canaveral to the International Space Station.
There was a 60 percent chance that the weather will OK for launch time.
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.
Col. Robert Pavelko, vice commander, 45th Space Wing, praised the work of all those involved in making this launch a success.
"Once again, we are proud to work hand-in-hand with SpaceX and NASA, as well as all our other mission partners in making this launch another success story coming from the Eastern Range," he said in a release.
