The (telemetry-driven?) sprite on the webcast seemed to flip over on landing, and there were noticeable deviations on the ωX/Y/Z °/s dials. Hope that's not real...

Audio-only on the JAXA feed right now in Japanese...essentially, they're 'still checking'.

As per here: <a href="https://eyes.nasa.gov/dsn/dsn.html" target="_blank">https://eyes.nasa.gov/dsn/dsn</a> There is definitely a signal from the lander, which at least rules out it having smacked into the regolith at tens of meters a second.

We're also getting telemetry from one of the rovers.
https://twitter.com/amsatdl/status/1748374331715981601 QUOTE This claims it was supposed to tip over. The IMU data suggests it's in the incorrect post-tip-over orientation, with the engines pointing up. Not sure how reliable that is though.

While it looks like things have not gone flawlessly, JAXA has an at-least-partly-functional vehicle on the Lunar surface. So I think it's time to say 'well done JAXA and the SLIM team'. At lot of smart and determined folks have tried this and ended up as a crater to be imaged by LRO.

If the rovers were deployed before touchdown, as per the plan, they could still accomplish their mission (since they can communicate directly with Earth)? Images would be very enlightening.

Andrew Jones reports radio detection of... something
QUOTE Anomalous behaviour from the #SLIM lander ~16:32:00 UTC. Signal has returned to previous behaviour. https://twitter.com/coastal8049/status/1748383389517004815 This feels like a Hayabusa-esque "Trying to fix an emergency in real time with scant data" situation. Fun! -------------------- -- Hungry4info (Sirius_Alpha)

They still had plenty of spare fuel at the time of touchdown. If it's on the wrong side, it may be possible to right it?

Maybe they are still able to correct the wrong attitude with the RCS thrusters?
That would be really daring...  Thorsten |

That may have been what the change in Doppler behaviour of the SLIM signal suggests occurred.
Scott Tilley now reports: QUOTE The ranging tones from #SLIM have stopped and remained absent for a few minutes now. No idea what this means, or even if it's bad news. Press conference has started! Edit: Nope! It was just an update to tell us that they'll start at 2:10 local (13 minutes from now). -------------------- -- Hungry4info (Sirius_Alpha)

News conference will start, and press release on JAXA web site, at 10mins past the current hour. ie. 02.10am in Japan Standard Time.
