Temperature of space is around 4K and the instruments were cooled to 1.4K. There is no system to capture and compress the gas after the phase change at these temperatures. The cooling system was designed to boil off helium. to keep the sensors cold. The same way an aerosol can gets cold after being used.
- ars 14y agoObviously at 4K there is more thermal noise than at 1.4K - but is there no value at all to the photos it can still take, even with some noise?
- yardie 14y agoThe vacuum is an infinite insulator. As the sensors get charged they have no ability to dissipate that energy. Eventually they'll get warmer and noisier, and you'll spend more time trying to clean up the images. It's been operating continuously for over 1000 days .I'm sure they have more data than they can currently process.
