NASA: Jet Propulsion Laboratory 2

	In my second tour I characterized a bolometric detector array. It is basically a very-very-very far-infra-red camera for a European space Telescope.
	Working in the Lab. Here we had to chill the detector down to 300mK. (That’s 0.3 degrees above absolute zero!). The tank to the right is liquid helium. The blue chamber holds the detector.
	I visited NASA-Dryden, just north of Los Angles. I looked over one of the two 747s that carry the Shuttle. A technician invited us to get into one of its turbofan inlets…so my friend and I took him up on his offer!
