NASA's BARREL Returns Successful from Antarctica

Three months, 20 balloons, and one very successful campaign: The Balloon Array for Radiation belt Relativistic Electron Losses (BARREL) team returned from Antarctica in March 2014.

High-Voltage Transmission Lines to Act as Antenna in First-of-its-Kind NASA Space-Weather Project

GSFC Heliophysics team will install scientific substations beneath high-voltage power transmission lines to measure in real-time a phenomenon known as geomagnetically induced currents (GICs).

Sun Emits a Mid-level Solar Flare

A mid-level flare burst from the sun on April 18, 2014, as seen as a bright spot in the center of this image. The image was captured by NASA's Solar Dynamics Observatory in 304 angstrom.

NASA's MMS Observatories Stacked For Testing

All four stacked Magnetospheric Multiscale, or MMS, spacecraft with solar arrays are ready to move to the vibration chamber at NASA's GSFC, where they will undergo environmental tests.

Solar Gusher

An active region blew out a flare (bright flash) and a dark rush of plasma spewing above the Sun (Apr. 4, 2014). Then the semi-transparent plasma seemed to turn and shift in planes.

GSFC Intern is semi-finalist in Siemens Competition

James Sullivan, a 2013 summer intern from the Thomas Jefferson High School for Science and Technology (Alexandria, VA), has been selected as a Semifinalist in the 2013 Siemens Competition in Math, Science and Technology. JamieĀ¹s research was on "Using Multi-Spacecraft Observations to Determine AKR Emission Cone Structure." His mentors were Shing Fung (673) and Leonard Garcia (Wyle/605/673).

The Heliophysics Science Division conducts research on the Sun, its extended solar-system environment (the heliosphere), and interactions of Earth, other planets, small bodies, and interstellar gas with the heliosphere. Division research also encompasses geospace -- Earth's uppermost atmosphere, the ionosphere, and the magnetosphere -- and the changing environmental conditions throughout the coupled heliosphere (solar system weather).

Scientists in the Heliophysics Science Division develop models, spacecraft missions and instruments, and systems to manage and disseminate heliophysical data. They interpret and evaluate data gathered from instruments, draw comparisons with computer simulations and theoretical models, and publish the results. The Division also conducts education and public outreach programs to communicate the excitement and social value of NASA heliophysics.
