International Space Station (ISS) astronauts received a cargo ship full of supplies, the National Aeronautics and Space Administration (NASA) mission said on Sunday. The NASA SpaceX cargo ship, Dragon, spent two days chasing the ISS following its launch from Cape Canaveral. Astronauts used a robot arm to capture the capsule 420 kilometers above Egypt. More than 2 tons of food, spacewalking gear, and experiments fill the Dragon, NASA said. On Wednesday, two American astronauts on board will conduct a spacewalk to replace a dead computer. NASA wants a reliable backup computer in place as soon as possible, even though the primary computer is still working. The backup computer failed on April 11.
