Radiation Hazards Of Deep Space Travel Quantified By Researchers
2013-11-19 09:06:48

April Flowers for redOrbit.com - Your Universe Online Comprehensive findings on space-based radiation as measured by a detector aboard NASA’s Lunar Reconnaissance Orbiter (LRO) have been published by a team of scientists led by the University of New Hampshire. The findings, published in a special edition of Space Weather, provide critical information on the radiation hazards that will be faced by astronauts on extended missions to deep space such as those to Mars. The findings...

New Theory Of ENAs At Edge Of Solar System Checks Out With Data

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online While our solar system contains many fascinating objects — planets, moons and the Sun, to name just a few — one of the most interesting and perplexing of these objects lies at its very edge. Our Sun sweeps charged particles through the solar system, encasing us in a cocoon that shields us from the interstellar environment. It is at the boundary of the solar system, where the solar wind slows and the...

Space Radiation Forecasts In Real Time
2012-10-16 14:06:24

Lee Rannals for redOrbit.com - Your Universe Online Astrophysicists have created the first online system for predicting and forecasting the radiation environment in near-Earth, lunar, and Martian space environments. The University of New Hampshire's Space Science Center (SSC) astrophysicists created the near real-time tool to provide critical information for potential manned missions to the moon and Mars. "If we send human beings back to the moon, and especially if we're able to go...

In a paper to be published in the April 10, 2011, issue of The Astrophysical Journal, scientists on NASA's Interstellar Boundary Explorer (IBEX) mission, including lead author Nathan Schwadron and others from the University of New Hampshire, isolate and resolve the mysterious "ribbon" of energy and particles the spacecraft discovered in the heliosphere "“ the huge bubble that surrounds our solar system and protects us from galactic cosmic rays. The finding, which overturns 40 years of...

SWRI -- When Voyager 1 finally crossed the "termination shock" at the edge of interstellar space in December 2004, space physicists anticipated the long-sought discovery of the source of anomalous cosmic rays. These cosmic rays, among the most energetic particle radiation in the solar system, are thought to be produced at the termination shock - the boundary at the edge of the solar system where the million-mile-per-hour solar wind abruptly slows. A mystery unfolded instead when Voyager data...
