Planck separates from upper stage
May 26, 2009
Planck will separate from the launcher about 30 minutes after launch, a couple of minutes after Herschel. The two spacecraft will independently head 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.
