At 19.44 hours GMT on 2nd January NASA’s space probe, STARDUST, successfully flew through Comet Wild 2, collecting interstellar particles and dust on its way. One of the instruments on board, the Dust Flux Monitor Instrument (DFMI), has been built by a team which include space scientists from the Open University.
Since its launch in February 1999, STARDUST has covered 3.2 billion km (2.3 billion miles). It is the first mission designed to bring samples back from a known comet. The study of comets provides a window into the past as they are the best preserved raw materials in the Solar System. The cometary and interstellar dust samples collected will help provide answers to fundamental questions about the origins of the solar system.
Professor Tony McDonnell and Dr Simon Green from the Open University’s Planetary and Space Science Research Institute (PSSRI) are currently at the mission command centre, the Jet Propulsion Laboratory in California, where they are beginning to receive data from their instrument.

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...
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...
