A $5 million University of Colorado at Boulder satellite dubbed the "Little Satellite That Did" now is expected to re-enter the atmosphere and burn up in early December following a successful six-year mission.
The Student Nitric Oxide Explorer, or SNOE, is carrying instruments that have measured nitric oxide in the upper atmosphere that affects Earth’s ozone layer, the intensity of X-rays from the sun and ultraviolet light from Earth’s aurora. Developed at CU-Boulder’s Laboratory for Atmospheric and Space Physics by students, engineers and faculty, the mission has been controlled from LASP’s CU Research Park facility 24 hours a day by students and faculty since early 1998.
"The SNOE satellite has been determining the influence of the sun on Earth’s upper atmosphere by measuring the amount of nitric oxide in the atmosphere," said Charles Barth, former LASP director and principal investigator of SNOE. Produced when solar X-rays are absorbed into the atmosphere, nitric oxide destroys naturally produced ozone when injected into the stratosphere 30 to 50 miles above Earth.

Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers
Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...
Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...

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...
