NavList:

A good effort from JAXA, and perhaps the electronics will survive until (and if) the solar panels are illuminated.

But, the important question:  who or what will be the first to do a "reverse lunar", that is, an observation from the Moon's surface of angular distance between star and Earth limb?  I doubt any of the landers over the next year or so will have anything like the needed optics, but with Starship able to set 100 t of payload onto the surface, surely they can spare a few kilograms for a sextant.  :-)

JAXA wants to verify the precision of their landing, though, and that will take better-than-sextant accuracy.  If the craft's retroreflector can see the Earth, then they're good.  Otherwise, it will have to be a photo from one of the lunar orbiters, or perhaps DSN ranging if the craft wakes up and the comms are set up for that.

Cheers,

Peter
