Replay of the Swarm liftoff on a Rockot launcher from the Plesetsk cosmodrome in northern Russia at 12:02 GMT (13:02 CET) on 22 November 2013.

The three-satellite Swarm mission aims to provide new information on the sources of the magnetic field inside Earth. This includes understanding how the magnetic field is related to the motion of molten iron in the outer core, how the conductivity of the mantle is related to its composition and how the crust has been magnetised over geological timescales.

It will also investigate how the magnetic field relates to Earth's environment through the radiation belts and their near-Earth effects, including the solar wind energy input into the upper atmosphere.
