Dragon was loaded with 5,700 pounds
of cargo when it arrived at the orbiting space hub. The cargo includes supplies for the crew living at the space station, spacewalk and science equipment.
The research supplies will support a number of experiments, like a study of malting barley in microgravity to help adapt it for use on long-duration spaceflights and a study of how fire behaves in space.
The Dragon capsule also contains a group of genetically enhanced “mighty mice”
that will help scientists understand how to limit muscle and bone loss in humans while they’re in space.
