In 2003, NASA's Spitzer Space Telescope launched into space to observe the infrared sky. It included a full tank of coolant to keep its sensitive instruments cold.

In 2009, Spitzer used up its coolant. It was too far from the Earth to be serviced. But amazingly, Spitzer has been able to continue operating using a reduced set of instruments.

In this spoof of old TV action shows--part of the IRrelevant Astronomy kids series--Sean Astin, Osa Wallander, and Betty White recreate a fictional account of Spitzer's transition from its coolant days to its new "Warm Mission," and explain some of the engineering behind how Spitzer produces its science.
