Astronauts Install the Space Station's Eighth and Final Roll-Out Solar Array in a 7-Hour Spacewalk

Anil Menon and Joshua Kutryk finished a power upgrade that took 18 spacewalks, and NASA says the orbiting laboratory's capacity will rise from about 160 kilowatts to roughly 215.

Can Gravitational Fields Break and Reconnect? A New Physical Review D Paper Says Einstein's Equations Allow It

NASA's Dragonfly Flies Its Hardest Titan Manoeuvre, Autonomously, in Its Most Thorough Simulation Yet

NASA Ends the Swift Mission After Nearly 22 Years as Its Orbit Decays and Re-Entry Looms

Swift saw over 2,000 gamma-ray bursts and fed some 7,000 papers; drag from a more active Sun pulled it down to 275 km, where its telescopes could no longer hold steady, and NASA stopped science.

Just 3% of the World's Glaciers Account for Over Half of Glacier Ice Loss, Study Finds

Glaciers that end in lakes, oceans or ice shelves lost 134 billion tonnes a year from 2000 to 2019, and lake-ending ones lost ice about 57 percent faster for their size.
