The Dragon spacecraft brought back a number of experimental results. One of the small aquatic animal experiments collected metabolic and genomic data on rotatoes to see if the freshwater creature, known for its resistance to radiation, was also resistant to radiation in microgravity. Another rodent study analyzed the role of muscle-producing inhibitors and activators in space, and the results could help slow muscle loss and osteoporosis caused by space flight in the future.

On December 5 last year, a Falcon 9 rocket sent the reusable Dragon spacecraft into space to deliver supplies and scientific equipment to the International Space Station.
