The Planck spacecraft in its transport container, in preparation for a flight to Rochambeau airport, French Guiana, where it is scheduled to be launched atop an Ariane 5 rocket. Planck will be launched with the Herschel spacecraft, though the two missions will separate shortly after launch and operate independently from each other.
Planck is a European Space Agency mission, with significant participation from NASA. NASA's Planck Project Office is based at NASA's Jet Propulsion Laboratory in Pasadena, Calif. NASA contributed mission-enabling technology for both of Planck's science instruments. U.S. and European Planck scientists will work together to analyze the Planck data.
