This is a 1h44m video describing in very technical detail how Starlink could use the direct-to-cell antenna on their latest satellites to image the whole globe at ~meters of resolution in real time: https://www.youtube.com/watch?v=jbp3kdJZ1_A
The simulations gets slightly more approachable in the last ~25% of the video. I like the theory that the "AI" datacenters they're pushing for will actually be to process this data and send it down in a usable format. Makes sense to me!
