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.

A new assessment of NASA's record of global temperatures revealed that the agency's estimate of Earth's long-term temperature rise in recent decades is accurate to within less than a tenth of a degree Fahrenheit, providing confidence that past and future research is correctly capturing rising surface temperatures.
The most complete assessment ever of statistical uncertainty within the GISS Surface Temperature Analysis (GISTEMP) data product shows that the annual values...
Physicists at the University of Basel are able to show for the first time how a single electron looks in an artificial atom. A newly developed method enables them to show the probability of an electron being present in a space. This allows improved control of electron spins, which could serve as the smallest information unit in a future quantum computer. The experiments were published in Physical Review Letters and the related theory in Physical Review B.
The spin of an electron is a promising candidate for use as the smallest information unit (qubit) of a quantum computer. Controlling and switching this spin or...

With a quantum coprocessor in the cloud, physicists from Innsbruck, Austria, open the door to the simulation of previously unsolvable problems in chemistry, materials research or high-energy physics. The research groups led by Rainer Blatt and Peter Zoller report in the journal Nature how they simulated particle physics phenomena on 20 quantum bits and how the quantum simulator self-verified the result for the first time.
Many scientists are currently working on investigating how quantum advantage can be exploited on hardware already available today. Three years ago, physicists...
'Quantum technologies' utilise the unique phenomena of quantum superposition and entanglement to encode and process information, with potentially profound benefits to a wide range of information technologies from communications to sensing and computing.
However a major challenge in developing these technologies is that the quantum phenomena are very fragile, and only a handful of physical systems have been...
