Miniature Exercise Device (MED-2)

The Miniature Exercise Device (MED-2), designed for future human spaceflight missions, will allow astronauts to meet their aerobic and exercise needs for long-duration flights.

The MED-2 produced in less than a calendar year at a fraction of the cost of traditional processes, weighs in at under 6% the mass of ARED, the resistive exercise device currently aboard the International Space Station, while also including aerobic exercise capabilities.

The MED-2 launched to the Space Station on March 22, aboard the Orbital ATK Cygnus cargo vehicle.
