Four 30- to 40-foot-long NASA suborbital sounding rockets were launched into the night sky within a period of 16 minutes as part of the HEX 2 project, a collaborative effort between the University of Alaska at Fairbanks and Clemson.
“We had absolutely ideal conditions for the launches,” said Clemson physics professor Miguel Larsen. “We are interested in the auroral displays because they produce electrical currents that heat the atmosphere. Wind patterns become altered as the atmosphere heats up, and this can cause changes in satellite orbits and interference with radio communications.”
The rockets carried chemical tracer experiments from Larsen and instruments from Clemson assistant physics professor Gerald Lehmacher. At 60 miles above the ground, the chemical tracer glows and can be tracked as it is carried by winds high up in the atmosphere. The instruments measured the changes in atmospheric pressure created by the heat.
The rocket range is located 30 miles north of Fairbanks. The data will be analyzed to yield a three-dimensional picture of the neutral winds and density changes that occur during auroral disturbances.
Twelve undergraduate and four graduate students from Clemson participated in the NASA-funded study.

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...
