Swedish instruments to study the Martian atmosphere in collaboration with Russia and China

07.11.2011
The Russian Phobos-Grunt spacecraft will be launched together with its Chinese sub-satellite Yinghuo-1 towards Mars from the Baikonur Cosmodrome in Kazakhstan on Tuesday evening (8 November 2011) CET, bearing three satellite instruments developed and built in Sweden.

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."

Im Focus: Scientists channel graphene to understand filtration and ion transport into cells

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.

To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...

Im Focus: Towards data storage at the single molecule level

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.

Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...

Im Focus: A space-time sensor for light-matter interactions

Physicists in the Laboratory for Attosecond Physics (run jointly by LMU Munich and the Max Planck Institute for Quantum Optics) have developed an attosecond electron microscope that allows them to visualize the dispersion of light in time and space, and observe the motions of electrons in atoms.

The most basic of all physical interactions in nature is that between light and matter. This interaction takes place in attosecond times (i.e. billionths of a...
