One month ago, SpaceX’s Dragon capsule arrived at the International Space Station. Now it’s time for the Dragon to come home. The return trip, a crucial part of its mission, brings scientific hardware, data and experiments down to waiting researchers.

Check out a few of the pieces of research taking that ride back to Earth.

A cinematic look at life and science aboard the space station

You may one day get to experience the product of The ISS Experience. A team is creating a cinematic virtual reality (VR) film from footage taken during in space covering crew life, execution of science and the international partnerships involved on the space station.

Every week or so, footage is transferred from the camera onto solid state drives – an original and a backup – for storage and downlinking. One of each pair of drives returns to Earth for editing and production.

Seeking Alzheimer’s understanding in microgravity

Amyloid fibrils, a conglomeration of proteins that can build up in the body, are associated with a number of neurodegenerative diseases such as Alzheimer’s and Parkinson’s diseases. The Amyloid Aggregation investigation assesses whether microgravity affects formation of these fibrils.

Samples exposed to microgravity are coming back to Earth using a facility that maintains a chilly temperature of -20°C. Teams on the ground must quickly retrieve the equipment and keep the samples at -20°C until they are analyzed.

The SPHERES return home

Synchronized Position Hold, Engage, Reorient, Experimental Satellites, or SPHERES, are bowling-ball sized satellites used to study formation flying, control algorithms and material science.

First sent to the station in 2006, these satellites have been employed in a dozen different investigations.

The Dragon brings back hardware from two recent experiments that examined the behavior of fluids in microgravity, SPHERES Tether Slosh and SPHERES-Slosh.

From microgravity lab to manufacturing facility

The Fiber Optic Production investigation created optical fibers on the space station using a blend of materials called ZBLAN to see whether making the fibers in microgravity has advantages over the process used on Earth. ZBLAN optical fibers offer high bandwidth for the telecommunications industry, and potential applications for uses like laser surgery and environmental monitoring.

The fiber produced on the space station is coming to Earth for testing to help verify previous studies and guide future efforts to manufacture large volumes of such fiber in microgravity.
