Latest Nathan Schwadron Stories
For NASA, manned missions to Mars and other deep-space destinations remain an essential goal. However, a new study reveals that researchers are only beginning to understand and characterize the radiation hazards such missions would encounter.
Comprehensive findings on space-based radiation as measured by a UNH-led detector aboard NASA’s Lunar Reconnaissance Orbiter (LRO) provide critical information on the radiation hazards that will be faced by astronauts on extended missions into deep space.
A new theory describes a so-called Retention Model that may help explain unusual data collected form the edge of our Solar System.
Astrophysicists have created the first online system for predicting and forecasting the radiation environment in near-Earth, lunar, and Martian space environments.
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 â€“ the huge bubble that surrounds our solar system and protects us from galactic cosmic rays.
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. A mystery unfolded instead when Voyager data showed 20 years of predictions to be wrong.
