The dual spacecraft is scheduled to arrive at Mars in October 2012. After insertion into orbit the two spacecraft will separate. Yinghuo-1 will stay on a highly elliptical orbit (800km x 80,000 km), whereas Phobos-Grunt will enter a more circular orbit in order to approach and land on the Martian moon Phobos.

The Swedish Institute for Space Physics (IRF) in Kiruna has provided three identical ion mass analysers for this mission. The Detector for Ions at Mars (DIM) is mounted on the main Phobos-Grunt spacecraft. The DIM sensor was developed and built at IRF, while the associated digital processing unit was built at the Russian Space Research Institute (IKI).
Yinghuo-1 carries a plasma package (Yinghuo Plasma Package, YPP) consisting of two ion mass analysers and an electron sensor. The package is a joint development between IRF and the National Space Science Center (NSSC) in China. IRF developed and built the ion mass analysers (YPP-i1 and YPP-i2), while NSSC has provided the associated digital processing units and the electron sensor. The Space Research Institute (IWF) in Graz, Austria, participates in the scientific aspects of the Yinghuo Plasma Package.
All three ion sensors will simultaneously investigate the interaction between the solar wind (a stream of charged particles from the sun) and the Martian atmosphere from different vantage points in space.
"We already have the ASPERA-3 instrument orbiting Mars on the European spacecraft Mars Express," says Dr Martin Wieser of IRF. "With all of these instruments in place we will be able to do multi-point plasma measurements from orbiting spacecraft for the first time at Mars."
Martin Wieser adds, "And thanks to Yinghuo's elliptical orbit, the Yinghuo Plasma Package will be able to explore the distant plasma tail of Mars -- another first."

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...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
