It appears that in fact the solar panels are facing west!
https://twitter.com/Cosmic_Penguin/status/1...312587131756589 Will there be generated solar power some time after local solar noon? Thorsten |

QUOTE (Thorsten Denk @ Jan 22 2024, 12:44 AM)  Will there be generated solar power some time after local solar noon? That's what that tweet says, yes. Presumably JAXA has good orientation data from the images they have received but not yet released. -------------------- Disclaimer: This post is based on public information only.

This was actually intended as a rhetorical question.
We'll see what happens. And it appears that the telemetry data of the probe's orientation in the live broadcast was indeed correct. The solar cells there also faced west. Thorsten |

Hungarian @astroKovacs has tweeted a very nice visualization of what might have made SLIM come to rest in such an apparently precarious orientation. The suggestion is that it may be touching a rock or a small crater wall rather than completely free-standing. We may know more about this on Friday.

Still nothing detected but JAXA was continuing to sweep/command as of 9 hours ago. Maybe tomorrow. https://nitter.net/coastal8049

From the JAXA Livestream update here -> https://www.youtube.com/watch?v=U61i0wN01Uk
My Japanese is non-existent but these look like surface images to me!

It seems there was some kind of engine failure during landing. If I understand this right, one of the engine nozzles seems to have followed its own independent landing trajectory.

They've confirmed that the lander is resting on the surface nose-down as expected.

And it looks like it has just one nozzle on top. The second nozzle broke off during the hover phase.

That's an extremely scenic bit of (Lunar) terrain!
Any ideas about why the nozzle broke off? Didn't Akatsuki also break a nozzle (I know, different time/place)? P |

Very cool images! Hopefully it can start working again soon (and if so, could it be righted with the remaining fuel on board)?
I wonder if any sign of the nozzle breakup is visible in that detailed telemetry we had from landing. Yes, it was Akatsuki that lost a nozzle when attempting Venus orbit insertion. Note sure if it's the same type of engine or not.... |

The falling nozzle is visible in this PDF PPT; look at slide 9, Right image. The camera has snapped the detached nozzle falling away. The Left image shows the same background terrain without the nozzle. Both views were taken by the navigation camera, looking straight down.
SLIM press conference slide show The nozzle is also visible a few slides later... |
