Livestream: Japanese probe Hakuto-R landing on the Moon. In roughly 16 minutes.

EDIT:
They cannot re-establish contact after losing communication in the final seconds before touch-down.

My guess is that it crashed. It was just a little bit too fast towards the end. It had maybe 10-30 kph when it hit the surface, which still could be too much for a fragile probe.

I am not sure how much radio silence they expected; but I think something may be wrong as they just turned the camera feed off the control room.

and blew the landing because they failed to reconcile English vs. metric math covering the landing. https://www.wired.com/2010/11/1110mars-climate-observer-report/

This stuff is not easy, not even when the mission covers millions of miles and everything goes exactly right until the last 5 minutes.

After they get over tomorrow's hangover after tonight's drunk, they'll realize that engineers learn more from disasters than they do when everything has gone exactly right. Expensive screwups provide the most data.

NASA learned to go 100% metric, down to the level of nuts, bolts, and box wrenches.
