Planckâ€™s cooling system composite
May 26, 2009
In order to achieve its scientific objectives, Planck's detectors have to operate at very low and stable temperatures. The spacecraft is therefore equipped with the means of cooling the detectors to levels close to absolute zero (-273.15Âº C), ranging from about -253 Âº C to only a few tenths of a degree above absolute zero.
