What the Heck Is This?

Easy enough to see this is some guy. But what's going on in the photo? So you know, the picture has not been flipped upside down.

Hint: This is serious work (you can tell by the coveralls) but also a heckuva lot of fun.

See a description of what the heck is going on and the full image below …

This guy and two others are floating in side an airplane on a zero-g trip, testing their made-for-space 3-D printer that's designed to print out parts for spacecraft. In multiple flights, they actually printed a simple wrench — the first tool ever printed partly in zero-g.

What a cool job!

Got a strange or interesting photo related to science, nature or technology? What the Heck, send it to me, and maybe I'll use it.
