Europe takes a look at midday today, from top to Earth: Three satellites then start to “Swarm” mission to observe Earth’s magnetic field. Follow the launch live with us.
The European Space Agency ESA shoots at noon today three satellites into space that are to investigate the vital magnetic field of the earth. The trio of mission “Swarm” (English, “swarm”) is expected to increase to 13.02 Central European Time Clock on board a Rockot rocket from the Plesetsk cosmodrome in northern Russia from the sky. The mission is to deliver the most precise data on strength, direction and variation of the magnetic field.
It is known that it is produced mainly by the Earth’s rotation – and that it is constantly changing. It is also known that it protects our planet from bombardment by charged particles in solar storms. Without this shield life on Earth would not be possible. However, the magnetic field as a shield has become weaker, so to be observed, the risk of cosmic radiation.
four years to discover the secrets of our cosmic shield the “Swarm” satellite. To this end, the trio will circle Earth in swarm formation and collect data – two probes in 460 kilometers, third in 530 km altitude. Each probe is equipped with five instruments, including a vector field magnetometer for precise measurement of the magnetic field direction.
In their observations of the geomagnetic field, the “Swarm” Mission to the data of the started in 2000 and still ongoing ESA science mission will be able to draw a “cluster”. The four “cluster” Satellite explore the conditions within the Earth’s magnetosphere and its interaction with the charged particles of the solar wind. You are at 10,000 kilometers from the earth – and so can the “Swarm” satellites on their orbits provide additional measurements
In addition to their scientific importance, the new ESA mission in the rest should be of quite practical use. Thus, the measurement data of “Swarm” could help to increase the accuracy of navigation systems. The earthquake prediction could be improved.
addition to “Swarm” to collect information about climate change. Are controlled by the Esa satellites in control center in Darmstadt.
