New model accurately predicts harmful space weather

A new, first-of-its-kind space weather model reliably predicts space storms of high-energy particles that are harmful to many satellites and spacecraft orbiting in the Earth's outer radiation belt. A paper recently published ...

Van Allen Probes prepare for final descent into Earth's atmosphere

Two tough, resilient NASA spacecraft have been orbiting Earth for the past six and a half years, flying repeatedly through a hazardous zone of charged particles known as the Van Allen radiation belts. The twin Van Allen Probes ...

2-D material has space vehicle applications

A new study from The Australian National University (ANU) has found a number of 2-D materials can not only withstand being sent into space, but potentially thrive in the harsh conditions.

System monitors radiation damage to materials in real-time

In order to evaluate a material's ability to withstand the high-radiation environment inside a nuclear reactor, researchers have traditionally used a method known as "cook and look," meaning the material is exposed to high ...

Researchers find space radiation is increasingly more hazardous

It might sound like something from a science fiction plot – astronauts traveling into deep space being bombarded by cosmic rays – but radiation exposure is science fact. As future missions look to travel back to the moon ...

Protecting astronauts from space radiation

(Phys.org)—The complexities of traveling to and working in space present challenges to astronauts that NASA scientists and engineers have been working on since Neil Armstrong and Buzz Aldrin first stepped on the moon more ...

Scientists provide window on space radiation hazards

Astrophysicists from the University of New Hampshire's Space Science Center (SSC) have created the first online system for predicting and forecasting the radiation environment in near-Earth, lunar, and Martian space environments. ...

Cosmic rays alter chemistry of lunar ice

Space scientists from the University of New Hampshire and multi-institutional colleagues report they have quantified levels of radiation on the moon's surface from galactic cosmic ray (GCR) bombardment that over time causes ...

Curiosity, the stunt double

With a pair of bug-eyes swiveling on a stalk nearly 8 feet off the ground, the 6-wheeled, 1800-lb Mars rover Curiosity doesn’t look much like a human being.  Yet, right now, the mini-Cooper-sized rover is playing ...
