Providing the Country with a cutting edge understanding of the Earth-Space environment, enabling us to better live, work, and study in space and here on Earth.
To ensure sustained scientific and technological progress, we provide foundations in theory, modeling, data analysis, data archival, instrumentation development, and mission formulation. We have an important role in enabling the development of long-lead technology and science as well as maintaining a knowledge base in fields necessary for the further development, safety, and security of our country.
Geospace Dynamics Constellation (GDC)
Exploring the Heart of Space Weather with the Geospace Dynamics Constellation
Doug Rowland | The Geospace Dynamics Constellation, or GDC, will provide the first direct global measurements of Earth’s atmospheric interface to space — a region where beauty and hazards co-exist - where space weather disturbances impact communication and navigation signals, satellite orbits, and induced currents that can trigger power outages on Earth. GDC’s unprecedented multi-point observations in the heart of this interface region will provide a generational shift in perspective on this region, allowing scientists to understand this complex, interconnected system as a whole.

Discovering Earth’s Third Global Energy Field
For nearly 60 years, scientists have studied the "polar wind," a stream of particles escaping Earth's poles into space, theorizing that a weak, unmeasured ambipolar electric field drives the outflow, a theory finally supported by recent findings. Learn more here: https://go.nasa.gov/3XcDDLD

HH-222: The Waterfall Nebula
What created the Waterfall Nebula? The origin is still being researched. The structure, officially designated Herbig-Haro 222, appears in the region of NGC 1999 in the Great Orion Molecular Cloud complex. The elongated gaseous stream stretches about ten light years but appears similar to a long waterfall on Earth. Recent observations indicate that HH-222 is likely a gigantic gaseous bow shock, similar to a wave of water caused by a fast-moving ship. The origin of this shock wave is thought to be a jet outflow from the multiple star system V380 Orionis off the lower left of the frame. Therefore, gas does not flow along the waterfall, but rather the entire structure moves toward the upper right. The Waterfall Nebula lies about 1,500 light years away toward the constellation of Orion. The featured image was captured earlier this month from El Sauce Observatory in Chile.
