  1. Yeah, it looks like it condensed from a cloud of small particles.

  2. Maybe with a Gravity Tractor: https://en.wikipedia.org/wiki/Gravity_tractor The idea is pretty simple. Just get a spacecraft close to the asteroid at a critical point and let the spacecraft's gravitational field deflect the asteroid so it misses the Earth. You'd need precise calculation and perfect timing, but the good part is that gravity will effect every loose rock.

  3. SO COOL!!! Thank you Scott Manley and Dante Lauretta for making this video! It's really fascinating. Just like landing on a planet, but not, because everything is so scaled down! At this level the water vapor your spacecraft absorbed from Earth's atmosphere before launch becomes a factor you have to take into consideration... Wow. I'm really intrigued by the landmark tracking optical navigation and the catalog of features OSIRIS Rex has in its memory. (Apologies if I'm getting this wrong, but it sounds like the onboard catalog is the landmark tracking.) It sounds like he's saying they originally planned to use LIDAR, but when they saw what the surface of Bennu was like they had to design the new optical navigation system from scratch. That's impressive!
