Artemis II Commander Reid Wiseman has been named Caltech associate vice president and deputy director of NASA’s Jet Propulsion Laboratory in Southern California. The emeritus astronaut and retired U.S. Navy captain begins his new role at NASA’s center of excellence for robotics and deep space exploration and at Caltech, which manages JPL for NASA, on […]
Over 1,645 Martian days, NASA’s Perseverance Mars rover measured the fine and ultrafine Martian dust particles found clinging to samples of spacesuit materials that are carried aboard the rover, including some that are small enough to penetrate the lungs and enter the bloodstream. The findings will be published Tuesday, Oct. 27, in the Proceedings of […]
Interstellar probes. Lunar drones. Helicopters on Mars. When a group of Caltech graduate students and enthusiasts began conducting rocket-propulsion tests in Pasadena’s Arroyo Seco on Oct. 31, 1936, they had no idea that their work marked the inception of the Jet Propulsion Laboratory. Ninety years later, the lab, now managed by Caltech for NASA, isn’t […]
A phenomenon rarer than a solar eclipse and more powerful than any single storm system is unfolding this fall, and NASA is tracking it closely. El Niño is a natural climate pattern that emerges roughly every two to seven years marked by warmer-than-normal water temperatures in parts of the equatorial Pacific. NASA scientists are keeping […]
A commercial lander that will be at the forefront of NASA’s efforts to establish a Moon Base, humanity’s first lunar outpost, has passed a series of critical tests at the agency’s Jet Propulsion Laboratory in Southern California. The tests simulated the extreme temperatures and vacuum of space, as well as the intense shaking and ear-splitting […]
NASA’s SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer) space telescope is shedding light on brown dwarfs, celestial objects that blur the line between stars and exoplanets. New findings published in The Astrophysical Journal show that these dark and cloudy worlds have chemically rich atmospheres not unlike the giant […]
A newly released panorama captured by NASA’s Curiosity rover offers the most detailed view yet of distant, wind-carved Martian cliffs, highlighting features the mission’s scientists have long been waiting to see up close. The scene was snapped at 8:30 a.m. local Mars time, showing striking blue hues in the foreground as bright morning light illuminates […]
Like tendrils on a vine, lava spreads out from the northern crater of Krasheninnikov, a volcano pair on the Pacific coast of Russia’s Kamchatka Peninsula. On July 30, 2025, an 8.8-magnitude earthquake had struck in the nearby ocean, apparently jolting one of the two volcanoes awake. A few days later, for the first time in […]
NASA announced Wednesday a mission to explore the history and evolution of the universe, PRIMA (PRobe far-Infrared Mission for Astrophysics), is advancing to the next phase of development. This space telescope is the first in a new class of NASA astrophysics missions, called Probe Explorers, within the agency’s longstanding Explorers Program. “The PRIMA mission is […]
Seasonal changes redistribute enough water around Earth to shift the planet’s center of mass back and forth by fractions of an inch relative to its geometric center. NASA scientists are on the case, tracking the oscillations because Earth’s center of mass is a crucial reference point for satellite navigation and elevation measurements. A team, led […]
