Following its longest hibernation period ever of nearly a year, NASA’s New Horizons spacecraft has emerged in good health and is ready to begin transmitting science data gathered in the distant Kuiper Belt far beyond Pluto. On June 23, flight…
As NASA prepares for a sustained human presence on the Moon, missions will increasingly require spacecraft that can navigate and communicate without a direct connection to Earth. NASA’s Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment, or CAPSTONE, validated…
A predawn Moon-and-planets meetup, a returning comet, a great chance to see the Milky Way, and Saturn’s rings at a new angle. Skywatching Highlights Transcript An early morning hangout with the Moon and planets, a comet swings by, prime time…
The Northwest Earth and Space Science Pathways (NESSP) project recently concluded its 2025–2026 ROADS (Rover Observation And Discoveries in Space) from Earth to Venus National Challenge, a NASA Science Activation program student challenge that engaged more than 500 students on…
NASA has selected Rocket Lab to provide the launch service for both the agency’s PolSIR (Polarized Submillimeter Ice-cloud Radiometer) and Total and Spectral Solar Irradiance Sensor-2 (TSIS-2) missions. The two selections are part of NASA’s Venture-Class Acquisition of Dedicated and…
Apollo astronauts previewed their roles as lunar field geologists in Alaska’s Valley of Ten Thousand Smokes.
As interstellar comet 3I/ATLAS began moving away from the Sun in December 2025, astronomers took the opportunity to turn NASA’s powerful James Webb Space Telescope in its direction and capture detailed measurements of its chemical components. The comet was freshly…
On a bleak stretch of the Colorado Desert in Southern California, a compact four-wheeled rover recently trundled about 16 miles (26 kilometers) with minimal intervention from the team of engineers trailing it. Called ERNEST (Exploration Rover for Navigating Extreme Sloped…
Even small asteroids lead complex lives. During its flyby of the asteroid Donaldjohanson last year, NASA’s Lucy spacecraft revealed the asteroid to be a wobbly, peanut-shaped body that has undergone a lot of activity in its relatively short history.
Results from Artemis II's science investigations will help support safe human exploration of deep space and provide a blueprint for how future missions will conduct science on the lunar surface as NASA builds a Moon Base and develops an enduring…
