Well sending them there is the easy part…
NASA streaming live as a probe arrives an asteroid. It’s going to touch down and take a sample for return in 2023.
Edit: More info
Also happening today: SpaceX launches 64 satellites into space on one rocket, with a booster that’s already been used twice. It’s their 19th launch of the year, surpassing their previous annual record of 18 from last year.
Is it touching down, or just reaching out a sampling arm? And with the size of the asteroid, is there even enough gravity to touch down?
It kind of bounces and samples while it’s in contact. To do an actual landing, you have to be very slow and careful
Hayabusa2 rover landing procedure:
Three times now! Watched it launch from my porch but couldn’t see it land - night launches are much better from a far away spectator standpoint.
And here’s video. Damn, it just never gets old watching a stage 1 touch down safely on a ship rocking away in the ocean.
Good stuff starts at around 20:00
That is so amazing :)
Yeah thanks for this!
More info on that asteroid mission.
It looks like today’s SpaceX launch (CRS-16) was their first booster landing failure in a while. The video feed from the booster showed a bit of loss of control, axial rotation and a grid fin forced hard over, and according to the commentary, the booster ‘made a water landing’.
The rest of the mission went as planned, though.
I am annoyed their feed cut off when things started going wrong and just said uh ‘water landing’ but everything is nominal! Which for the primary mission was absolutely true, but annoying. The landings are by far the best part and missing a crash? God damn it!
Rocket spotters have your back:

Musk Twitter says the problem was a stalled grid fin hydraulic pump, which caused the uncontrolled roll you see in the clip. All told, they did pretty well given the issue. It was a soft landing in the water, and it’s still sending telemetry.
Oh man thanks! That was perfect. What a heroic effort on the rocket’s part. I figured once things started spinning out of control it would be a more spectacular crash but it looks like it almost pulled it off.
And now we have the video from the booster all the way down to the water: https://twitter.com/elonmusk/status/1070399755526656000
Nice, I like how it pulled off a Wile E. Coyote moment there before realizing you can’t actually land a rocket on the ocean’s surface.
Maybe I’m just a weirdo for thinking this but the way it got from out of control to a “controlled crash” is more impressive than if nothing had gone wrong at all.
No not all. I have had similar thing happen to me many times in Kerbal, and I can count on one finger the number of times they didn’t end in a disaster. SpaceX is as good as Scott Manley, maybe better :).
I’m curious what’s NASA reaction to it is though. Will they impressed at that fast reaction or concerned that fin grid got stuck in the first place?
