SUMMARY:Present and Future Far Infrared Extragalactic Astronomy: Herschel 
 and Beyond - Matt Griffin\, Cardiff University

DESCRIPTION:The far infrared and submillimetre spectral region is critical
  to the characterisation of the obscured Universe\, both in our own and ne
 arby galaxies and at high redshift. The Herschel Space Observatory\, which
  is currently operating\, has a passively cooled 3.5-m diameter telescope 
 and three scientific instruments which are carrying out sensitive imaging 
 and spectroscopy at wavelengths between 55 and 671 microns. I will describ
 e the design and scientific capabilities of Herschel and review some of it
 s early results.\n\nFor a comprehensive understanding of the interstellar 
 medium in galaxies over cosmic time\, and the relationship between AGN and
  their host galaxies\, future space-borne observations will be needed with
  much improved sensitivity and angular resolution in the far infrared. The
  Japanese-led Space Infrared telescope for Cosmology and Astrophysics (SPI
 CA) will be the next major far infrared space astronomy mission. It will c
 arry a 3.2-m telescope cooled to ~ 6 K by mechanical coolers\, and a suite
  of instruments covering the 5 – 200 micron range. The cold aperture wil
 l lead to a huge increase in sensitivity over current far infrared facilit
 ies. SPICA ’s far infrared camera and spectrometer\, SAFARI \, will cove
 r the wavelength range between 30 and 200 microns with an observing speed 
 orders of magnitude faster than that achieved by Herschel. I will outline 
 how SPICA ’s capabilities will bring about a major advance in our abilit
 y to investigate the extragalactic Universe
