Mars Express radar to be deployed in May

02.05.2005


Following green light for the deployment of ESA’s Mars Express radar, given in February this year, the radar booms are now planned to be deployed in the first half of May.



Once the deployment is successful, the Mars Express MARSIS radar will enable the first European spacecraft to orbit Mars to complement its study of the planet’s atmosphere and surface.

MARSIS (Mars Advanced Radar for Subsurface and Ionosphere Sounding instrument) is the first antenna of its kind which was also designed to actually look below the surface of Mars at the different layers of material, most notably for water.


The deployment of the three MARSIS radar booms is an operation which will take place in three phases, in a window spanning from 2 to 12 May 2005. These operations will be initiated and monitored from ESA’s European Space Operations Centre (ESOC) in Darmstadt, Germany.

Each boom will be deployed separately, with the two 20-metre ‘dipole’ booms to be unfurled first and the 7-metre ‘monopole’ boom to follow a few days later.

Before each deployment, the spacecraft will be placed in a ‘robust’ attitude control mode, which will allow it to tumble freely while the boom extends before regaining standard pointing to the Sun and Earth.

After each deployment, the control team will conduct a full assessment of the spacecraft status before a decision is taken to proceed with the next phase.

The result of each deployment can be assessed only after a series of tests, each taking few days. After the deployment of the three booms, ESA engineers will start the analysis of the complete behaviour of the satellite to be able to confirm the overall success of the operation.

The current schedule is subject to changes, because the timing of the complex series of operations cannot be all fixed beforehand. A status report will follow in due course.

Once the deployment is complete, MARSIS will undergo three weeks of commissioning before the start of actual science investigations, ready for when one of the prime regions of interest for radar observations comes into the right position through the natural evolution of the spacecraft’s orbit.

The MARSIS instrument was developed by the University of Rome, Italy, in partnership with NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California, USA.

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...
