On 14 May at 13:12:02 UT (15:12:02 CEST) the Herschel and Planck spacecraft lifted off on board an Ariane 5 ECA from the European spaceport in Kourou, French Guiana. After the flawless launch the two spacecraft separated and embarked on their individual journeys to L2.

Successful launch, 14 May at 13:12:02 UT
Both spacecraft now on their way to L2
