It was located via thermal image which I find interesting for something that far away.

It was spotted from the satellite which carried it there and is now orbiting the moon. Not too far I guess.

That's actually a pretty great accomplishment to find it so quickly. When Apollo 11's Eagle was on the moon no one could figure out where it was. The orbiter couldn't spot it and mission control had all these detailed maps and telemetry and couldn't get the right spot based on data and descriptions from the astronauts of what they were looking at. Seeing something on the moon is hard.

Something designed as an unmanned orbiter will have better sensors than a "man in a can" like the Apollo Command Module.

Also the 50 years factor. Digital camera that we use today started to sell in the market at around year 2000. And then those were only VGA resolution 640x480 pixel.
