An important window for RBSP and SAMPEX to share data about the radiation belts was quickly closing, so the Relativistic Electron Proton Telescope (REPT) instrument was turned on only two days after launch, instead of the originally-planned 30 days.
NASA's RBSP missing successfully launched this morning at 4:05 a.m. EDT. The twin probes were released from the rocket's Centaur upper stage one at a time and sent off into different orbits, kicking off the two-year mission to study Earth's radiation belts.
A recent study, appearing online in the JGR on February 29, 2012, has found clear evidence on Venus for a type of space weather outburst quite common at Earth, called a hot flow anomaly. These anomalies, also known as HFAs, cause a temporary reversal of the solar wind that normally moves past a planet.
NASA's Goddard Space Flight Center in Greenbelt, Md. is pleased to announce that its Space Weather App, previously only available for iPhone users, is now available for users of Android smartphone and tablet users.
Chief space weather forecasters Yihua Zheng and Antti Pulkkinen are helping to implement a computer technique ( Ensemble Forecasting ) that will improve NASA’s ability to predict the path and impact of severe solar storms.
Auroras are but one part of a complex system of magnetic fields and charged particles surrounding Earth. Instruments on FASTSAT are beginning to paint a picture of how the different components act in concert.
Doug Rowland and his team recently secured another flight opportunity for a pint-sized instrument studying lightning in Earth's upper atmosphere and now are bracing for a veritable "fire hose" of data about a little-understood phenomenon first discovered by scientists nearly two decades ago.
A NASA led team of scientists and engineers has repositioned two small probes from Earth’s orbit where they studied space weather to begin orbiting the moon to study its interior and surface composition.
On July 14th, astronauts onboard the International Space Station (ISS) witnessed a broad curtain of green auroras over the southern hemisphere. The display was caused by a solar wind stream which hit Earth's magnetic field on July 12th.
