The SpaceX company’s supply ship, Dragon, pulled up at the orbiting lab early Monday, two days after departing Cape Canaveral, Florida. Station commander Butch Wilmore used a robot arm to grab the capsule and its 5,000 pounds of precious cargo.
The space station’s six astronauts were getting a little low on supplies. That’s because the previous supply ship — owned by another company — was destroyed in an October launch explosion. NASA scrambled to get replacement equipment aboard Dragon, as did school children who rustled up new science projects. Then Dragon was stalled a month late by rocket snags.
