While we wait: animation with all pictures from the approach until the last one half an hour ago.

French representative focusing on the international collaboration in space exploration in spite of growing geopolitical tensions, and praising Japan's long-term vision.

Queen's Brian May joining the party too.

Applause, probably transition to final descent?


TOUCHDOWN!

More applause, probably confirming sample collection took as long as expected and Doppler shows a good flyout.

apart from applause I didn't hear the commentary confirming touchdown, shooting and sampling.

They did say applause was because "the sequence was developing as intended". Since there's no telemetry, this is as good a confirmation as it's gonna get until 20 minutes from now.

so it's an applause just for the schedule?  :)
Current telemetries (generated at 22:08, recieved at 22:27 and uploaded to web at 22:50) still say "44m".

I'm really confused. Landing wasn't meant to be for another 8 minutes, with confirmation not coming for another 19 minutes after....  :o
Watched B1019 land in person 21/12/2015.

Reminiscing about Hayabusa-1 in Itokawa, where they didn't manage to get much sample (but thankfully some dust got it!) and the bus got so damaged because of unforeseen problems, which in the end weren't damning. I remember following that on Space.com when this website didn't exist yet :)

No, remember they're following Doppler since the 45-m mark was crossed. They're comparing the Doppler velocities with the scheduled ones.

It has definitely not been an hour since hovering ops at 45m began.  ???

True, but since the probe was supposed to be autonomous at that time, I wonder if it could decide it was ready to go down earlier than scheduled.

Could any of these telemetries be related to touchdown, shooting, sampling,...?

    44m range on the LIDAR. (Laser/Radar). So still hovering...

    Incredibly confusing coverage from JAXA, but it does appear a touchdown!

    Ok I think there was some confusion between Ryugu time and Earth time.
    TD occurred 19.1 minutes ago and telemetries should be arriving right now.
