It's also possible to receive infrared images using the same technique, which can be used in part to visualize the water vapor content of the atmosphere:
Some parts of the imaging instrument (ABI) on GOES-17 responsible for keeping it cool failed shortly after launch, causing the temperature to vary over the course of the day:
This doesn't affect the "visible" light images too much, but can cause all sorts of problems for the infrared, which is used scientifically for various cloud measurements, sea surface temperature, land surface temperature, etc. It's still up in the air how useful we can make this data.
