Asteroid landing

Can't see a thread on it, so thought I would post as personally find extremely cool.

Basically probe (think Star Trek) lands on relatively small asteroid for samples.

About the size of a sky scraper apparently.

Still haven't got the results yet, but half the battle done.

Must have taken some pretty cool maths

I watched it live. It went off perfectly. Back to Earth in 3 years.

God those engineers are so young these days. Not a cigar, pocket protector or slide rule in sight.

So this is actually intended to return a sample to Earth. Cool. I'm surprised I haven't heard of it before.

Asteroids have so little gravity that it's more like docking with them than landing.

The probe did creep up on the asteroid very slowly (described in the live transmission) and it was spring loaded "like a Pogo-stick".

I also watched live.....and the youth of the team really struck me as well.

God I feel like a dinosaur. I can do the vision processing that was described. I'm sure they were doing a Kalman filter for estimating position uncertainty, and I know how to do that.......but I seriously doubt I could keep pace with those kids (i.e. people under 40, and some under 30, and a couple of recent college grads just for good measure.)

I wanted to make it a team event for our Robotics team, have the students all watch as part of a Zoom event and talk about how they did it afterwards, but the coach wasn't into it.

I thought it was cool, though.

But just enough gravity that it's harder than either.
