Astronaut Mike Hopkins prepares for his first space walk.
CubeSats shown in space. The small satellites contain power and data systems. The cubes, among other missions, collect electrons from the plasma surrounding Earth. Scientist will use this knowledge to study space craft propulsion.
Thank you to NASA for the above pictures.

CubeSats are a form of research spacecraft.
