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.
Scientists will fly two pair of rockets. One in each pair will collect data about the neutral and charged gas particles through which it travels. The other will shoot out a long trail of lithium gas to track the wind movement.
This week, officials have gathered in Washington DC to ask themselves a simple question: What if it happens again? The purpose of Space Weather Enterprise Forum (SWEF) is to raise awareness of space weather and its effects on society especially among policy makers and emergency responders.
A CME propelled toward Earth on June 21 may be moving slower than originally thought. Our Space Weather Lab analysts have downgraded the probable speed to 400 mph (650 km/s). Impact is now expected June 24 at 3am EDT (0700 UT). Forecasters now predict a relatively mild G1-class geomagnetic storm when the cloud arrives.
The Plasma Impedance Spectrum Analyzer (PISA) has now completed more than 120 days over the course of six months since it was first turned on. The Miniature Imager for Neutral Ionospheric Atoms and Magnetospheric Electrons (MINI-ME) is functioning well after six months in space. The Thermospheric Temperature Imager (TTI) has collected more than 50 days of data.
Scientists analyzing recent data from NASA's Voyager and Cassini spacecraft have calculated that Voyager 1 could cross over into the frontier of interstellar space at any time and much earlier than previously thought.
