Jules Verne ATV was launched from Europe's Spaceport in French Guiana at 05:03 CET on 9 March. First contact between Artemis and the ATV was established at 06:46, exactly on schedule.
Artemis communicates with Jules Verne, receiving telemetry and sending telecommands, each time the two spacecraft are within sight of one another. During every ATV orbit, there is around 40 minutes of continuous contact. Artemis will provide dedicated support to Jules Verne throughout the free-flying phase of its mission - up to the docking planned for 3 April. After docking, Artemis' data relay resource will be shared between ATV and ESA's Envisat Earth observation mission.
Artemis is in geostationary orbit over the Atlantic Ocean. It has three main purposes:
the provision of voice and data communications between mobile terminals in remote areas of Europe and North Africa, as well as in the Atlantic performing a key role within Europe's EGNOS satellite navigation system by broadcasting enhanced GPS and GLONASS signals for use by civilian 'safety critical' transport and navigational services the provision of inter-orbit satellite communication using advanced S- and Ka-band radio links and laser technology
Artemis is operated from ESA's facility at Redu, which houses the spacecraft's mission control centre and a Ka-band ground terminal with a 13.5-metre dish antenna.
The task of communicating with Jules Verne is shared between Artemis and NASA's Tracking and Data Relay Satellite System (TDRSS).
The inter-orbit communications services provided by Artemis are precursors to a proposed future European satellite data relay system.

Researchers explore ultrafast control of magnetism across interfaces: A new study discovers how the sudden excitation of lattice vibrations in a crystal can trigger a change of the magnetic properties of an atomically-thin layer that lies on its surface.

Wind turbines could be installed under some of the biggest bridges on the road network to produce electricity. So it is confirmed by calculations carried out by a European researchers team, that have taken a viaduct in the Canary Islands as a reference. This concept could be applied in heavily built-up territories or natural areas with new constructions limitations.
The Juncal Viaduct, in Gran Canaria, has served as a reference for Spanish and British researchers to verify that the wind blowing between the pillars on this...
