Artemis is currently cruising at ~3535 km per h - which is the fastest humans have ever gone outside of a gravity well.

It is 0.0003273% of c - so, the astronauts watches will be ticking slow due to relativity at only 99.99999999946432% of normal, which is roughly 1.689 milliseconds in 10 years (if they were to hold current speed).

Provided I've done the sums right, which I think I have. #space #science

Have you ever...

Home #3dprinting is fun. I like making fun things like #ttrpg minis, and useful things, like a spice rack organizer.

I like how they fit into #solarpunk story telling.

But until/unless one can recycle and more importantly, produce filament, it's still a centralized technology based on plastic.

I've only worked with basic PLA, and read a bit about PETG & the differences.

Are there any filament technologies that are recyclable / reusable or that can be produced locally from raw materials?
