Scientists unraveling mysteries of Earth's Van Allen radiation belts
Co-author Harlan Spence, director of the UNH Institute for the Study of Earth, Oceans, and Space, principal scientist for the ECT, said that the acceleration they first reported operates on the scale size of an electron's gyromotion-it is a really local process, maybe only a few hundred meters in si

NASA spacecraft probe mysteries of Earth's radiation belts
"Now we're seeing this large-scale, global motion involving ultra low-frequency waves pulsing through Earth's magnetosphere and operating across vast distances up to hundreds of thousands of kilometers," said Harlan Spence, director of the UNH Institute for the Study of Earth, Oceans, and Space and

NASA launches twin satellites to study Van Allen radiation belts
"We need eight (instruments) because we're measuring across this huge energy range," said Harlan Spence, a principal investigator from the University of New Hampshire. "From particles that are very, very low energy -- in our units we talk about going down to one electron volt, very low energy -- to
"We've got a whole series of things going off, and they take different times to arrive, so they're all piling on top of each other," Harlan Spence, an astrophysicist at the University of New Hampshire, told SPACE.com. "It complicates the forecasting and predicting because there are always inherent u

'Space hurricane' from the sun sweeping over our planet
"For parts of Europe already, and further points to the east, we should expect to see strong magnetic storm conditions," astrophysicist Harlan Spence, the director of the University of New Hampshire's Institute for the Study of Earth, Oceans, and Space, told Space.com. "There's a very good chance to

'Dramatic' solar flare could disrupt Earth communications
"Certainly over the (two-year) lifetime of the mission this is the most significant event," said Harlan Spence, principal investigator for the cosmic ray telescope for the effects of radiation, or CRaTER.
