Launch milestone achieved: last-ever look at CryoSat

30.09.2005


As preparations for the launch of CryoSat on 8 October continue on schedule, the satellite has now been sealed beyond physical control from the outside world.



On 26 September, the two half-shells of the payload fairing were fastened, encapsulating CryoSat. They will not be opened again until the spacecraft has left the atmosphere on its way to final orbit deployment 717 kilometers about the Earth.

The delicate operation of joining CryoSat to the Breeze upper stage took place a few days ago. Once the electrical interfaces had been checked and the outer fabric-layer of the thermal insulation blanket had been adjusted, the final ’red-tagged’ items were removed from the spacecraft before the fairing was carefully closed. This was time for the ESA and Astrium engineers at the Plesetsk Cosmodrome to take a step back and take one last look at ’their’ satellite.


Now that the fairings are closed, the explosive-equipment is being installed. A number of electrical tests will be performed on the Breeze stage before the thermal cover and ventilation system are added. Then, on Saturday 1 October, the Breeze carrying CryoSat will be rolled out to the launch pad where it will be mated with the lower two stages of the Rockot launcher.

Once locked to the launcher, the engineers will verify that contact with the satellite can be established and start charging the battery. Additional electrical tests will follow and a launch rehearsal will take place on 5 October. The Rockot launcher will then be fuelled ready for launch on 8 October.

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...
