How much cryogen does Spitzer have remaining in its dewar? Do they know, or are they just waiting to see a temperature rise after complete boil-off? Can't find much info on the website.

Can anyone tell us how long Spitzer might operate for in its "warm" mission ? About 10.5 years, it turns out. (Am I allowed to quote to same question every other decade?) Here's a countdown clock for the Jan 30th decommissioning: http://www.spitzer.caltech.edu/final-voyage 6002 days in space. |
