From August to October, NASA’s PUNCH (Polarimeter to Unify the Corona and Heliosphere) mission tracked comet 2025 R2 (SWAN) — one of the thousands of comets discovered in images from the SOHO (Solar and Heliospheric Observatory) spacecraft, a joint mission between NASA and ESA (European Space Agency) that launched 30 years agoContinue Reading
Researchers from NASA’s Jet Propulsion Laboratory in Southern California monitor a research drone in the Dumont Dunes area of the Mojave Desert in September as part of a test campaign to develop navigation software to guide future rotorcraft on Mars. NASA/JPL-Caltech A researcher monitors LASSIE-M (Legged Autonomous Surface Science InContinue Reading
As ESA (European Space Agency) and NASA’s SOHO (Solar and Heliospheric Observatory) turns 30 on Tuesday, a lot has changed in how we understand our Sun and the space weather it creates since the mission’s launch. When the SOHO mission began on Dec. 2, 1995, space weather — the conditions in space influencedContinue Reading
NASA is marking America’s 250th year with a bold new symbol of the nation’s relentless drive to explore. The America 250 emblem is now on the twin solid rocket boosters of the SLS (Space Launch System) rocket for Artemis II — the powerhouse that will launch a crew of fourContinue Reading
The asteroid Bennu continues to provide new clues to scientists’ biggest questions about the formation of the early solar system and the origins of life. As part of the ongoing study of pristine samples delivered to Earth by NASA’s OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer) spacecraft, threeContinue Reading
As the last Ice Age waned and the Holocene dawned, deep-ocean circulation around Antarctica underwent dramatic shifts that helped release long-stored carbon back into the atmosphere. Deep-sea sediments show that ancient Antarctic waters once trapped vast amounts of carbon, only to release it during two major warming pulses at theContinue Reading
The stretch of the river through Albuquerque has run dry twice since 2022, after not doing so for decades, impacting all forms of life that depend on its flows. By Tina Deines ALBUQUERQUE, N.M.—On a late July morning, a snapping turtle, about 18 inches in length, sat solemnly in aContinue Reading
Outside Reno, Nev., a massive data center campus is being built to support artificial intelligence. The center sits in the nation’s driest state and will need billions of gallons of water to operate.Continue Reading
