The Herschel Space Observatory will be the largest ever infrared space observatory when it is launched in 2009. Equipped with a 3.5 metre diameter reflecting telescope and instruments cooled to close to absolute zero, Herschel will observe at wavelengths that have never previously been explored. After a four-month journey from Earth, Herschel will spend a nominal mission lifetime of three years in orbit around the second Lagrange point of the Sun-Earth system (L2). The European Space Agency's Herschel will collect long-wavelength radiation from some of the coldest and most distant objects in the Universe. In addition, Herschel will be the only space observatory to cover a spectral range from the far infrared to sub-millimetre. Astrium is responsible for the telescope, the integrated payload module and satellite integration and testing. |
