On 13 February, a Russian rocket carried the antenna of the Icarus mission to the International Space Station (ISS). The Icarus on-board computer was thus joined by another key component of the orbiting animal tracking system. Using the system developed by scientists from the Max Planck Society in cooperation with the Russian space agency Roscosmos, the German Aerospace Center and the University of Konstanz, researchers around the world will be able to study the movements of animals and determine the conditions in which they live.
