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
