While you might need an account to access the underlying data, you don't need an account to view the imagery

Holy shit, it gives you near-IR and visual spectra every ~60 hours. This is amazing. I feel like a spy in a late cold-war novel.
I raise you GOES-17 aka GOES-West currently:

Though it’s a trade off! GOES has a really fast return (10-15 minutes, IIRC) but doesn’t do global and has comparatively poor spatial resolution (red at 500m per pixel, many near IR at 1km, LWIR at 2km). So you can get some data every 15 minutes, but for the city of San Francisco it’s only 10x10 pixels.

This is part of why folks like to join high-resolution data with high-temporal frequency data like GOES. Including me! (Well, I hope to get back to my side project using the Descartes Labs API to “learn” high-spatial GOES from the combo of sentinel2 and GOES).

NOAA satellites are great. I used something a while back to check to see if a relative's house was OK after some wildfires.
