SpaceX launches supplies to space station
April 19, 2014 09:42
The SpaceX company returned to orbit today, launching fresh supplies to the International Space Station after more than a month's delay.
The Dragon cargo ship will reach the orbiting lab on Sunday Easter morning. That pushes urgent spacewalking repairs to Wednesday; NASA wants a bad computer replaced before something else breaks.
This was the second launch attempt this week for SpaceX. NASA's commercial supplier had a leaky rocket valve Monday.
The valve was replaced, and the company aimed for a liftoff today despite a bad forecast. Storms cleared out of Cape Canaveral just in time for the afternoon launch.
The unmanned cargo ship contains 2 tons of station supplies, including material originally intended for the spacewalking repairs.
A critical backup computer failed outside the space station last Friday. The primary computer is working fine, but numerous systems would be seriously compromised if it broke, too. A double failure also would hinder visits by the Dragon and other vessels.
