Everything from stem cells that could help us understand how human cancers start and spread after being exposed to near zero-gravity, to equipment that is paving the way toward servicing and refueling satellites while they're in orbit will be on board.

After Dragon is recovered off the west coast of Baja California, some of the cargo will be removed and returned to NASA immediately while Dragon itself is prepared for a return trip to SpaceX's test facility in McGregor, Texas. There, the processing and further unloading of scientific samples and returning station hardware will continue.

A variety of technological and biological studies are returning in Dragon. The Microgravity Expanded Stem Cells investigation had crew members observe cell growth and other characteristics in microgravity. This information will provide insight into how human cancers start and spread, which aids in the development of prevention and treatment plans. Results from this investigation could lead to the treatment of disease and injury in space, as well as provide a way to improve stem cell production for human therapy on Earth.
