ESA’s Herchel-Planck Launch
Following on from NASA successful launch to the Hubble Space Telescope, ESA will be launching two probes on one Arianne rocket today.
The Herschel Space Observatory is a far-infrared telescope and detector which, at 3.5 meters wide, will be using the largest mirror ever deployed in space. Planck is a spacecraft which will be observing the Cosmic Microwave Background Radiation at a much high resolution and sensitivity than before.
The satellites, with a joint launch cost of €1.1 billion, will be carried into space by an Ariane 5 ECA rocket.
