I find it amazing how civil satellite can be kept in orbit, be it geostationary or not, and monitor "millions of points" spread to some great km and be able to detect (or provide image with enough resolution) so that a move of few cm can be detected.

Most countries launch EOS's that are either civilian grade or considerably lesser than that.

Only the US has really the ability to fund the crazy bus sized EOS platforms.

Himawari is a Japanese weather satellite that is 8m long and weighs 3.5 tons.

Block III and newer K-11 platforms are 20 meters in length and weight 20,000 KG.

Also the dry mass of Himawari is 1300 kg, it's based on the MELCO DS-2000 bus which is meant for communication satellites, it doesn't have an 8M telescope assembly.
