The rocket carried the payload to 175 miles altitude before descending and landing by parachute. Payload recovery is in progress. The experiment team reports that great data was received during the flight. ![]() The DEUCE payload sits atop a NASA Black Brant IX sounding rocket at the White Sands Missile Range in New Mexico.

NASA’s Magnetospheric Multiscale Spacecraft finds new Magnetic Event in near Earth EnvironmentWritten by Mara Johnson-Groh
Magnetic reconnection is one of the most important processes in the space — filled with charged particles known as plasma — around Earth. ![]() In a turbulent magnetic environment, magnetic field lines become scrambled. As the field lines cross, intense electric currents (shown here as bright regions) form and eventually trigger magnetic reconnection (indicated by a flash), which is an explosive event that releases magnetic energy accumulated in the current layers and ejects high-speed bi-directional jets of electrons.(NASA Goddard’s Conceptual Image Lab/Lisa Poje; Simulations by: University of Chicago/Colby Haggerty; University of Delaware/Tulasi Parashar) «Read the rest of this article» Sections: Technology | No Comments
NASA’s THEMIS Mission helps reveal mystery of Pulsating AuroraWritten by Mara Johnson-Groh
While scientists have long known auroras to be associated with solar activity, the precise mechanism of pulsating auroras was unknown. Now, new research, using data from NASA’s Time History of Events and Macroscale Interactions during Substorms — or THEMIS — mission and Japan’s Exploration of energization and Radiation in Geospace — shortened to ERG, or also known as Arase — satellite, has finally captured the missing link thought responsible for these auroras. «Read the rest of this article» Sections: Sports | No Comments
NASA’s Van Allen Probes mission and FIREBIRD II CubeSat discover Whistling Space Electrons’ OriginsWritten by Mara Johnson-Groh
Yet for decades, no one has known exactly what is responsible for hurling these energetic electrons on their way. Recently, two spacecraft found themselves at just the right places at the right time to witness first hand both the impulsive electron loss and its cause. ![]() The Van Allen Belts, shown in green in this illustration, are concentric doughnut-shaped belts filled with charged particles, trapped by Earth’s magnetic field.

NASA’s Van Allen Probes celebrates 5 years of studying Van Allen Radiation BeltsWritten by Mara Johnson-Groh
But NASA’s Van Allen Probes have been traveling through this hazardous area since August 30th 2012 – they are now celebrating their fifth year in space studying this dynamic region. ![]() The two Van Allen Probes work as a team, following one behind the other to uniquely observe changes in the belts.

NASA’s Van Allen Probes discover human made Barrier around the EarthWritten by Mara Johnson-Groh
At times, these interactions can create a barrier around Earth against natural high energy particle radiation in space. These results, part of a comprehensive paper on human-induced space weather, were recently published in Space Science Reviews. «Read the rest of this article» Sections: Technology | No Comments
NASA prepares Satellites for alignment of Planets and StarsWritten by Mara Johnson-Groh
One of these geometric events — the spring equinox — is just around the corner, and another major alignment — a total solar eclipse — will be visible across America on August 21st, with a fleet of NASA satellites viewing it from space and providing images of the event. To understand the basics of celestial alignments, here is information on equinoxes, solstices, full moons, eclipses and transits: ![]() During a transit, a planet passes in between us and the star it orbits. This method is commonly used to find new exoplanets in our galaxy. (NASA’s Goddard Space Flight Center/Genna Duberstein) «Read the rest of this article» Sections: Technology | No Comments
