That is one of the events which can happen when spending some amount of time orbiting a planet. I've had that one, and one where Sumire wants to get down on the ground to inspect some ruins she discovered by scanning from Orbit. Think the three options are; 1) Tell her to let it be 2) Tell her she can scan as good as possible from Orbit or 3) Allow her to spend time on the ground inspecting said ruins. Only had it once, and it gave me some morale allowing her down to the planet (no idea if there are other outcomes though)I encountered a new one the other day, I think it may have been tied to the world (agroculture). I unfortunately wasn't paying super close attention, but it was something along the lines of 'the locals have agro mechs, they're running poorly, yang is excited to inspect them'.
Pretty sure it was the standard 3 options: No, partial support, full support. I chose the full support option (Yang and his team spend time overhaul the mechs maybe?) and it gave me a pretty good tech boost.
So I suspect there are various orbital events as well, and the events can be different according to the type of planet. Remains to be seen though.
