NASA’s crawler-transporter 2, carrying NASA’s Artemis II SLS (Space Launch System) rocket with the Orion spacecraft, arrives Wednesday, Feb. 25, 2026, inside the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida. NASA NASA completed the agency’s Artemis II Flight Readiness Review on Thursday, March 12, and polled “go”Continue Reading
This pair of images shows stars observed Feb. 6, 2026, by the SPARCS space telescope simultaneously in the near-ultraviolet, left, and far-ultraviolet, right. The fact that one star is seen in the far-UV while multiple are seen in near-UV offers insights into the temperatures of these stars, with the oneContinue Reading

Transforming Flight Building on a legacy of aeronautical research that can trace its origins to the earliest days of powered, heavier-than-air flight, NASA remains committed to transforming aviation by improving operational efficiency while maintaining safety in more crowded skies, and paving the way for revolutionary aircraft shapes and propulsion thatContinue Reading
A potentially strong El Niño weather pattern will likely emerge this summer and persist through the rest of the year. The hottest years on record generally occur in years when El Niño is active. (Image credit: Joe Raedle)Continue Reading
Two powerful instruments of the NASA/ESA/CSA James Webb Space Telescope joined forces to create this scenic galaxy view. This spiral galaxy is named NGC 5134, and it’s located 65 million light-years away in the constellation Virgo. ESA/Webb, NASA & CSA, A. Leroy Stars peek through the dusty, winding arms ofContinue Reading
For two decades, NASA’s Automated Lunar and Meteor Observatory has helped scientists track meteors, observe impacts on the Moon, and better understand the space environment future explorers will face. The Automated Lunar and Meteor Observatory, or the ALaMO, at NASA’s Marshall Space Flight Center features two observatory domes, a 15-meterContinue Reading
1 min read Help Galaxy Zoo: Tidal Tales Open Cosmic Storybook Galaxies carry the imprints of past encounters. When they pass near one another or collide, gravity pulls their stars into long tails, thin streams, and faint shells – features that preserve the history of these dramatic events. Thanks toContinue Reading
Space Launch System (SLS) NASA is developing the most powerful rocket in the agency’s history to return astronauts to the Moon and establish a sustainable lunar presence. The Space Launch System (SLS) will be the first exploration-class rocket since the Saturn V, the rocket used in the Apollo missions, andContinue Reading
Download PDF: Efficient Large Displacement/Large Rotation Dynamic Simulations Using Nonlinear Dynamic Substructures Utilizing reduced-order dynamic math models (DMM) in linear system-level dynamic analyses is a well-known practice that enables extreme computational efficiencies. But what about nonlinear system dynamics? Reduced-order DMMs have found their way into contact dynamics. The engineer mustContinue Reading
The old, reliable technology has experienced slow growth, but industry leaders see opportunities ahead. By Dan Gearino The International Energy Agency’s executive director has called hydropower a “forgotten giant,” and has urged governments to do more to remember it. U.S. President Traitor 47 has said hydropower is “fantastic,” a sharpContinue Reading
Governments are fighting to hold oil giants like Exxon Mobil accountable for their well-documented efforts to deceive the public about climate change.Continue Reading
