The first astronauts on Mars probably won’t live in a tin can like the International Space Station. Big, heavy structures are expensive to launch, and aren’t great at protecting against the radiation they’d be pummeled with on Mars. Instead, the first Martians might live in something like a pop-up tent.
Damn. That laser is something. It’s a specially designed LasX proton laser art system that blasts a beam to make art at lightning speeds. The CAD file for the design, called After Sunset, was created by Andy Gikling and was imported to the laser control software and then zapped out onto the chalkboard to etch the design. How cool is that?
