Major Mars Express Scheduled Orbit Change Successful

30.12.2003


This morning, at 09:00 CET, the first European mission to Mars registered another operational success. The Mars Express flight control team at ESOC prepared and executed another critical manoeuvre, bringing the spacecraft from an equatorial orbit into a polar orbit around Mars.



All commands were transmitted to Mars Express via ESA’s new Deep Space Station in New Norcia, Australia. This morning, the main engine of Mars Express was fired for four minutes to turn the spacecraft into a new direction, at a distance of 188 000 kilometres from Mars and about 160 million kilometres from Earth. On 4 January 2004, this new polar orbit will be reduced even further.

Fascinating ESA science mission ahead


In a polar orbit, Mars Express can now start to prepare its scientific observation mission as planned, working much like an ’Earth-observation satellite’ but around Mars. From the second half of January 2004, the orbiter’s instruments will be able to scan the atmosphere, the surface and parts of the subsurface structure of Mars with unmatched precision.
The MARSIS radar, for example, will be able to scan as far as four kilometres below the surface, looking for underground water or ice. The High Resolution Stereo Camera will take high-precision pictures of the planet and will begin a comprehensive 3D cartography of Mars. Also, several spectrometers will try to unveil the mysteries of Martian mineralogy and the atmosphere, as well as influences from the solar wind or seasonal changes.

Mars Express closes in on Beagle 2 landing area

The change of orbit by the Mars Express orbiter will allow increasingly closer looks at the Beagle 2 landing site, which measures 31 kilometres by 5 kilometres. In this narrowing polar orbit, the orbiter will fly directly over the landing site at an altitude of 315 kilometres on 7 January 2004, at 13:13 CET. The reduced distance, the ideal angle of overflight and originally foreseen communication interfaces between the ’mother’ and ’baby’ will increase the probability of catching signals from the ground.

Ongoing European co-operation and international support

The Mars Express flight control team of ESA in Darmstadt, Germany, is in regular contact with its colleagues of the Beagle 2 team and with NASA ground stations. In addition, ESA receives regular support or offers of support from the Jodrell Bank radio telescope in the UK, Westerborg telescope in the Netherlands, Effelsberg telescope in Germany and Stanford University’s telescope in the USA. ESA is grateful for this spirit of dynamic international co-operation on its first mission to Mars.

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...
