Right now, we are working to downlink the first images from the lunar surface.

  It’s not a jab. There were suspicions that it landed sideways because communication was lost then became very faint right after touch down.

  They were concerned about not landing upright in the live stream: https://www.youtube.com/watch?v=Dg2ffigGcYM&t=5678s https://www.youtube.com/watch?v=Dg2ffigGcYM&t=5678s "looks like we had excellent pitch and yaw control throughout, but I did see a little bit of a roll excursion. could it be that we landed off-angle in roll in the final phase?"

    That would have lined up with the signal issues too. Glad it wasn’t the case.

    I was thinking that because it was a roll excursion, assuming that’s along the axis intersecting the plain of the landing legs, it’s not a matter of being upright but rather a matter of being pointed in the wrong direction. Because they’re landed near the south poll of the moon, and because the moon is tidally locked to the earth and always shows us the same side, I imagine they have a very specific angle they need to be at to be looking at the earth just over the moon’s horizon.

Does anybody know what kind of software was patched? Some Ada/C++ code?

  The 'what' could really be anything since the article is vague, from the sensors themselves to the GNCP software that takes that info and controls the spacecraft. If they were patching the instrument(s) then they could have done anything from uploading a new configuration to memory or the even loading a new FSW build. Based on the little info in there I'm guessing the LIDAR hardware is their already planned backup system so when the primary sensors didn't function as planned they switched over. In this scenario I'd expect the controllers to want to hold off so they can configure the LIDAR and run its self test procedures as well as configure GNCP and ground control. I would bet money they are using c++.
