Photoconductor Array Camera and Spectrometer
PACS is one of three science instruments for ESA's Herschel Space Observatory (HSO). It operates either as an imaging photometer or an integral field spectrometer over the spectral band from 57 to 210 µm. PACS has been designed and built by a consortium of institutes and university departments from across Europe under the leadership of MPE.

satellite launch: 2009 May 14
actual status: the orbit around Lagrange Point L2 will be changed to
an orbit around the Sun (to free space at L2)
end of mission: 2013 April 29
