Asteroid Mining
This is something that is obviously far in the future and still extremely difficult to do.
However the video below is real. That’s real video from a real spacecraft lander, landing on a comet. The white cliff on the left is ice, the white dots on the right are stars.
The little rocks are little rocks.
This is comet 67P from the Kuiper belt, we landed on it in 2016 with a probe called Philae.
Philae was 100kg probe, and obviously if you want to mine an asteroid (or comet) you need to send something big enough to send stuff back to Earth (or somewhere useful).
But it’s weird that we did this 10 years ago, and sort of just memory holed it. A lot of things that happen in space get forgotten quickly, even when the videos are as cool as this one.
