Radio Four is airing a two-part documentary talking to the engineers and astronomers working on the Herschel Space Telescope as they approach the biggest milestone in the 20 year project.
British scientists from the University of Cardiff head the international consortium which designed and built Herschel's Spire instrument, a sophisticated camera that operates simultaneously at different wavelengths.
Herschel was launched in May this year and expected to answer some of the biggest questions about the origins of the Universe.
