+ - Successful Launch of ESA's Herschel and Planck

Submitted by

rgarbacz writes "Today at 13:12 GMT ESA launched successfully new and long awaiting spacecrafts: Herschel — the 3.5m mirror infrared telescope, and Planck — the CMB mapper. The spacecrafts were carried by Arian 5, which lifted off from Kourou in French Guiana. They will stay in L2 to perform the research. Herschel and Planck are one of the most expensive and important missions of the European Space Agency. They were built to perform measurements with an outstanding quality. Planck will measure CMB with accuracy below 1%, over 10 times better than the previous such mission (WMAP). Because of this high sensitivity both spacecrafts are cooled to temperatures close to the absolute zero by on board liquid helium, and staying in L2 is very helpful to maintain this state. Both spacecrafts are designed to observe the Universe at its infancy, Herschel — the first stars (those real ones), and galaxies (whichever came first), Planck — the first photons which were set free, the so called cosmic microwave background radiation (CMB).

This is a correction to my previous submission — please remove this line."
