Video: NASA unboxes a delivery to Earth from the Space Station

A fascinating unboxing video of special cargo from the International Space Station. In this video from NASA's Marshall Space Center, Quincy Bean, principal investigator for the space station printer, removes and inspects the first items ever created in space with a 3-D printer.

To protect the space-manufactured items, they must remain in bags until inspection is complete and testing begins at NASA's Marshall Space Flight Center in Huntsville, Alabama. More than 20 parts were "unboxed" on April 6, 2015, at Marshall's Additive Manufacturing Laboratory. Additive manufacturing has the potential to change the way we resupply the space station and will be critical for deep space missions to Mars, asteroids and other places.
