The RBSP mission seeks to characterize the Van Allen Radiation Belts, which contain 99% of the universe's electrified gas. The study will address questions about particle origins, mechanisms giving them extreme speed and energy, and their effects on Earth's magnetosphere.
BARREL aims to measure X-rays produced by charged particles entering Earth's atmosphere, helping scientists understand risks to spacecraft and humans in space. The 45 payloads will be launched on balloons around Antarctica as part of a NASA mission, combining with RBSP measurements for more accurate data.
Researchers used data from orbiting spacecraft to discover that energetic electrons are swept away by solar wind particles during periods of heightened solar activity. The findings aim to improve predictions of geomagnetic storms and protect satellites and astronauts.
Recent AGU research highlights increased flood fatalities in Africa due to population trends, not climate change, as well as lake warming caused by climate change. The study also found that the ozone hole affects upper-atmosphere temperature and circulation, while solar wind contains more oxygen than previously thought.
Scientists using NASA's THEMIS spacecraft have discovered the connection between 'singing' chorus waves and the generation of hiss, which helps clear killer electrons from Earth's radiation belts. The new research confirms that chorus waves can be refracted into the inner portion of the radiation belts by dense plasma near Earth.
Dartmouth College researcher Robyn Millan will lead a NASA project launching over 40 high-altitude balloons from Antarctica to study the Earth's Van Allen Belts. The balloons will carry instrumentation to better understand how the belts release radiation into near-Earth space, which can be hazardous to astronauts and satellites.
The Radiation Belt Storm Probes – Energetic Particle, Composition, and Thermal Plasma (RBSP-ECT) project will measure the behavior of charged particles causing space radiation. The study aims to achieve a better understanding of the physical processes controlling the shape and intensity of Earth's radiation belts.
A proposed US system to protect satellites from solar storms could disrupt high frequency radio wave transmissions and GPS navigation globally. The 'radiation belt remediation' system may lead to intense HF blackouts around the world, isolating remote communities for up to seven days.
The Johns Hopkins Applied Physics Lab will design and operate NASA's Radiation Belt Storm Probes, which will study Earth's radiation belts and improve space weather forecasting. The mission aims to predict potentially hazardous space weather effects and better characterize planetary space environments.
A team of British, US, and French scientists have made a breakthrough in understanding the behavior of high-energy particles in the Van Allen radiation belts. They found that low-frequency radio waves cause particle acceleration and intensify the belts, contradicting long-held theory.
The Van Allen Radiation Belt Slot, considered a safe zone, filled with concentrated radiation during the October and November 2003 solar storms. The radiation surge was the most intense ever observed in this region, posing significant risks to spacecraft.
