Description : On 15 May 2009 the onboard liquid helium supply was exhausted.
Without liquid helium to cool the telescope to the very low temperatures needed to operate, most of the instruments are no longer usable. However, the two shortest-wavelength modules of the IRAC camera are still operable with the same sensitivity as before.
