NASA Atmospheric Wave-Studying Mission Releases Data from First 3,000 Orbits

Following the 3,000th orbit of NASA’s AWE (Atmospheric Waves Experiment) aboard the International Space Station, researchers publicly released the mission’s first trove of scientific data, crucial to investigate how and why subtle changes in Earth’s atmosphere cause disturbances, as well as how these atmospheric disturbances impact technological sy

NASA’s Record-Shattering, Theory-Breaking MMS Mission Turns 10

Since its launch on March 12, 2015, NASA’s MMS, or Magnetospheric Multiscale, mission has been rewriting our understanding of a key physical process that is important across the universe, from black holes to the Sun to Earth’s protective magnetic field.

Cosmic Mapmaker: NASA’s SPHEREx Space Telescope Ready to Launch

NASA’s latest space observatory is targeting a March 8 liftoff, and the agency’s PUNCH heliophysics mission is sharing a ride. Here’s what to expect during launch and beyond. In a little over a day, NASA’s SPHEREx space telescope is slated to launch from Vandenberg Space Force Base in California aboard a SpaceX Falcon 9 rocket. […]

NASA’s EZIE Launching to Study Magnetic Fingerprints of Earth’s Aurora

High above Earth’s poles, intense electrical currents called electrojets flow through the upper atmosphere when auroras glow in the sky. These auroral electrojets push about a million amps of electrical charge around the poles every second.

NASA CubeSat Finds New Radiation Belts After May 2024 Solar Storm

Key Points The largest solar storm in two decades hit Earth in May 2024. For several days, wave after wave of high-energy charged particles from the Sun rocked the planet. Brilliant auroras engulfed the skies, and some GPS communications were temporarily disrupted.

NASA Solar Observatory Sees Coronal Loops Flicker Before Big Flares

For decades, scientists have tried in vain to accurately predict solar flares — intense bursts of light on the Sun that can send a flurry of charged particles into the solar system. Now, using NASA’s Solar Dynamics Observatory, one team has identified flickering loops in the solar atmosphere, or corona, that seem to signal when […]

NASA’s LEXI Will Provide X-Ray Vision of Earth’s Magnetosphere

A NASA X-ray imager is heading to the Moon as part of NASA’s Artemis campaign, where it will capture the first global images of the magnetic field that shields Earth from solar radiation. The Lunar Environment Heliospheric X-ray Imager, or LEXI, instrument is one of 10 payloads aboard the next lunar delivery through NASA’s CLPS (Commercial […]

NASA’s Parker Solar Probe Makes History With Closest Pass to Sun

Operations teams have confirmed NASA’s mission to “touch” the Sun survived its record-breaking closest approach to the solar surface on Dec. 24, 2024. Breaking its previous record by flying just 3.8 million miles above the surface of the Sun, NASA’s Parker Solar Probe hurtled through the solar atmosphere at a blazing 430,000 miles per hour […]
