More than a decade ago, technologist Fred Herrero realized that to truly understand the ever-changing dynamics of Earth’s upper atmosphere, he would need an armada of satellites gathering simultaneous, multipoint measurements.
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.
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.
NASA Earth and space simulations are getting a boost from graphics processing units (GPUs), with early results on laboratory and NASA Center for Climate Simulation GPU systems demonstrating potential for significant speedups.
April 21, 2011 marks the first anniversary of the Solar Dynamics Observatory (SDO) first solar observation, referred to as "first light". In honor of this occasion we would like you to vote for your favorite video from SDO"s first year in operations.
Bob Benson tells tales of winters he used to know in Minnesota, the South Pole, and Alaska. A five-decade career studying Earth's ionosphere - the part of Earth's atmosphere that reflects radio communication waves - has taken him to some extreme latitudes.
