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: Manipulating Electron Spins Without Loss of Information

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.

For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...

Im Focus: The proton precisely weighted

What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.

To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
