As preparations for the launch of CryoSat on 8 October continue on schedule, the satellite has now been sealed beyond physical control from the outside world.
On 26 September, the two half-shells of the payload fairing were fastened, encapsulating CryoSat. They will not be opened again until the spacecraft has left the atmosphere on its way to final orbit deployment 717 kilometers about the Earth.
The delicate operation of joining CryoSat to the Breeze upper stage took place a few days ago. Once the electrical interfaces had been checked and the outer fabric-layer of the thermal insulation blanket had been adjusted, the final red-tagged items were removed from the spacecraft before the fairing was carefully closed. This was time for the ESA and Astrium engineers at the Plesetsk Cosmodrome to take a step back and take one last look at their satellite.

Quantum optical sensor for the first time tested in space – with a laser system from Berlin
23.01.2017 | Ferdinand-Braun-Institut Leibniz-Institut für Höchstfrequenztechnik
For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.
According to Albert Einstein's Equivalence Principle, all bodies are accelerated at the same rate by the Earth's gravity, regardless of their properties. This...

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
