Scientists compile data from IBEX, NASA's twin Voyager spacecraft, and computer models to show that the heliosphere just isn't moving fast enough to create a bow shock in the tenuous and highly magnetized region in our local part of the galaxy.
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.
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.
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.
Over December 2010 and January 2011, testing continued on two of FASTSAT's three onboard science instruments. The Plasma Impedance Spectrum Analyzer (PISA) and the Miniature Imager for Neutral Ionospheric Atoms and Magnetospheric Electrons (MINI-ME). The third science instrument, the Thermosphere Temperature Imager (TTI), is scheduled for activation on February 1st.
GODDARD, Md: Update on the three Goddard experiments supporting Heliophysics and space weather instrument technology development and research; PISA, MINI-ME, and TTI. All three successfully completed their aliveness tests in late November.
