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 Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
