Herschel and Planck cruise to L2
May 23, 2009
Shortly after launch, Herschel and Planck will separate from the launcher's upper stage and head independently towards their respective orbits around the second Lagrange point of the Sun-Earth system (L2), some 1.5 million km from Earth in the direction opposite to the Sun. It will take about 60 days for both spacecraft to reach their destination.
