SLIM is a small Japanese lunar lander planned to launch this year.

Here:

is an article about it, with some images, describing two small landers which will deploy from it and operate on the surface.

In Japanese. Open in something which will offer a translation if required.

One thing I noticed and don't understand is that the IMU (lower left corner) was showing normal lunar surface gravitational acceleration at landing but the bar changed color from green to yellow. Don't know what the color coding indicates, but given the attitude graphic does this imply that the lander is indeed upside down?

That would explain the array not charging, but if so why are they getting telemetry unless it has a very robust omni antenna? Or maybe there's one on the ventral surface for use during cruise.

Presumably the lower left is the vector sum of the three accel axes and doesn't say anything about orientation, and they only display the angular rates, not the absolute angles. But one imagines they wouldn't draw it upside down if it weren't in fact oriented that way.
