The Spectral and Photometric Imaging Receiver (SPIRE) comprises a three-band imaging photometer and an imaging Fourier transform spectrometer. The instrument will be used to undertake large area deep sky photometric imaging surveys and allow follow-up spectroscopic observations of selected sources. These observations will help tackle two of the most fundamental questions in astronomy: how and when did galaxies form and how do stars form?
