On May 21, ground controllers powered down NASA’s AWE (Atmospheric Waves Experiment) instrument, bringing the data collection phase of the mission to a successful and scheduled end, surpassing its planned two-year mission. Installed on the exterior of the International Space…
A new Sun-centered and science-focused coloring book produced by NASA in partnership with the University of Alaska Fairbanks (UAF) is now available for people to learn while showing their artistic side.
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…
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…
Patches of the Sun’s surface often show strong magnetic fields. These fields can emerge within a matter of hours, and can decay slowly or quickly, sometimes over days, weeks, or even months. Thanks to a new study about these long-lived…
Editor’s Note: NASA updated this article on Wednesday, March 11, to reflect confirmation of Van Allen Probe A’s re-entry. NASA’s Van Allen Probe A re-entered Earth’s atmosphere at 6:37 a.m. EDT on Wednesday, March 11, almost 14 years after launch. From 2012 to 2019, the spacecraft and…
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…
A total lunar eclipse will redden the Moon in the early morning hours of March 3, 2026. Here’s what you need to know.
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…
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…
