Heads up! @NOAASatellites' GOES-18, launched in March 2022, is now #GOESWest. Miles above Earth, it’ll observe the Western Hemisphere, helping weather forecasters, emergency managers, and all who want to know more about our changing planet.

This is awesome, of course. But, how does a satellite observe *only* one hemisphere? Whether North, East, South, or West, does not a satellite always observe them all, even if partially? Edit: OK, I acknowledge that a geostationary orbit will observe only one hemisphere, and if placed in a perfectly positioned location, will only ever observe one hemisphere. At 90°W, there we have it. Mea culpa
