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.
