Earth’s magnetic field is like a powerful trap. It lures electrically charged particles in space, near our planet, and snares them in an invisible, doughnut-shaped pen around Earth known as the ring current. This captive swarm of charged particles plays an important role in how Earth reacts to changing conditions in space, called space weather, which […]

NASA’s STORIE Mission to Tell Tale of Earth’s Ring Current
Earth’s magnetic field is like a powerful trap. It lures electrically charged particles in space, near our planet, and snares them in an invisible, doughnut-shaped pen around Earth known as the ring current. This captive swarm of charged particles plays an important role in how Earth reacts to changing conditions in space, called space weather, which […]
To Protect Artemis II Astronauts, NASA Experts Keep Eyes on Sun
As four astronauts travel around the Moon on NASA’s Artemis II mission, they will venture beyond Earth’s protective magnetic field. The crew’s spacecraft, Orion, will carry and protect them as they journey into deep space and serves as the main protection against the Sun’s intense power. During their 10-day flight, NASA and the National Oceanic and Atmospheric Administration (NOAA) will monitor the […]
NASA’s Van Allen Probe A to Re-Enter Atmosphere
NASA’s Van Allen Probe A is expected to re-enter Earth’s atmosphere, almost 14 years after launch. From 2012 to 2019, the spacecraft and its twin, Van Allen Probe B, flew through the Van Allen belts, rings of charged particles trapped by Earth’s magnetic field, to understand how particles were gained and lost. The belts shield Earth from cosmic radiation, solar storms, and the constantly streaming […]
NASA’s ESCAPADE Ready to Study Space Weather from Earth to Mars
Mars is not what it used to be. Once warm, watery, and blanketed by a thick atmosphere, today the Red Planet is cold, dry, and draped by a thin atmospheric veil. The main culprit is a relentless stream of particles from the Sun, known as the solar wind. Over billions of years, the solar wind has stripped away […]

NASA Back for Seconds with New Food System Design Challenge
NASA is getting ready to send four astronauts around the Moon with Artemis II, laying the foundation for sustainable missions to the lunar surface and paving the way for human exploration on Mars. As the agency considers deep space endeavors that could last months or years, it must develop ways to feed astronauts beyond sending […]
NASA’s IMAP Mission Captures ‘First Light,’ Looks Back at Earth
All 10 instruments aboard NASA’s newly launched IMAP (Interstellar Mapping and Acceleration Probe) mission have successfully recorded their first measurements in space. With these “first light” observations, the spacecraft is now collecting preliminary science data as it journeys to its observational post at Lagrange point 1 (L1), about 1 million miles from Earth toward the […]
NASA’s Carruthers Geocorona Observatory Reveals ‘First Light’ Images
NASA’s Carruthers Geocorona Observatory has captured its first images from space, revealing rare views of Earth and the Moon in ultraviolet light. Taken on Nov. 17 — still months before the mission’s science phase begins — these “first light” images confirm the spacecraft is healthy while hinting at the incredible views to come. The initial […]
