 Context examples 

The observations were made during Spitzer's "warm mission," a phase that began in 2009 after the observatory ran out of liquid coolant, as planned.

(The 'Serpent' star-forming cloud hatches new stars, NASA)

When put under pressure, plastic crystals of neopentylglycol yield huge cooling effects – enough that they are competitive with conventional coolants.

(Green material for refrigeration identified, University of Cambridge)

The same Cambridge-led team identified an inexpensive, widely available solid that might compete with conventional coolants when put under pressure.

Spitzer's Multiband Imaging Photometer (MIPS) instrument took this image during Spitzer's cold mission, which ran from the spacecraft's launch in 2003 until 2009, when the space telescope exhausted its supply of liquid helium coolant. (This marked the beginning of Spitzer's warm mission.) Infrared light can't be seen by the human eye, but warm objects, from human bodies to interstellar dust clouds, emit infrared light.
