A SpaceX Starlink satellite suffered a major in-orbit failure in December 2025, losing communication after venting its fuel tank and beginning an uncontrolled orbital descent. The malfunction caused the satellite’s altitude to drop and produced minor debris, prompting close tracking by SpaceX, NASA and the U.S. Space Force. High-resolution imagery from Maxar/Vantor...

Russia’s Energia rocket company has patented a rotating space station concept designed to generate artificial gravity for astronauts. The system would use spinning habitable modules to simulate half of Earth’s gravity, potentially reducing health risks linked to long missions as the International Space Station nears retirement.

Astronomers have detected strange wobbling jets in the rare sun-facing tail of interstellar comet 3I/ATLAS. Observed as the comet neared the Sun, the shifting jets reveal new details about how material escapes from comets formed around other stars, offering rare insight into alien planetary systems.

POSTECH researchers have developed a “dream battery” using magnetic control of lithium to prevent dendrite formation. The hybrid anode stores lithium safely, offers four times the capacity of graphite, and sustains stable cycling, creating a safer high-energy solution for EVs and energy storage.
