Robots in orbit are becoming even more popular. There are still many technical challenges ahead.

Robots will be one of the keys to the expanding in-space economy. As launch costs decrease, hopefully significantly when Starship and other massive lift systems come online, the most significant barrier to entry for the space economy will finally come down. So what happens then? Two acronyms have been popping up in the literature with …
