Mind the gap: A study found that women published 8.9 papers for every 10 published by men before the COVID-19 pandemic, but this has now dropped to 8.8 papers (courtesy: iStock_FOTOGRAFIA-INC) Astronomers published more papers per year during the COVID-19 pandemic than they did beforehand – but men enjoyed a disproportionate share of the increase.

HELSINKI — China has laid out its pathway for robotic and crewed lunar and deep space exploration, with a number of missions building towards a permanent moon base. Three upcoming robotic missions will set in place landers, orbiters, relay satellites and test key technologies needed to begin construction of China’s International Lunar Research Station (ILRS)

SEOUL, South Korea – India’s space agency ISRO launched a one-ton Earth observation satellite and eight nanosatellites to sun-synchronous polar orbit Nov. 26 aboard the nation’s workhorse Polar Satellite Launch Vehicle (PSLV) rocket. The rocket lifted off from the Satish Dhawan Space Centre at 1:26 a.m. Eastern. The launch was live-streamed on YouTube, which showed

Together for the first time. She’s a longtime SLS critic who served a decade in senior NASA roles under Clinton and Obama. He’s a Republican ex-congressman who ran NASA for three years under Trump. Both are bullish on commercial space. You won’t want to miss SpaceNews’ first year-end luncheon since 2019. We will also get a look ahead

WASHINGTON — A brand new SpaceX Falcon 9 successfully launched a new cargo Dragon spacecraft Nov. 26, carrying supplies, experiments and new solar arrays for the International Space Station. The Falcon 9 lifted off from the Kennedy Space Center’s Launch Complex 39A at 2:20 p.m. Eastern. The rocket’s upper stage deployed the Dragon spacecraft into

An artist’s impression of the star Betelgeuse going supernova. (Courtesy: European Southern Observatory/L. Calçada) Massive stars in their “red supergiant” phase become around 100 times fainter in the visible part of the electromagnetic spectrum in the last few months before they collapse and explode as a supernova. This is the finding of researchers from Liverpool

WASHINGTON — NASA’s Orion spacecraft entered a high-altitude orbit around the moon Nov. 25 in the latest major step in the Artemis 1 uncrewed test flight. The Orion spacecraft fired the main engine in its European Service Module at 4:52 p.m. Eastern for 88 seconds. The maneuver changed the velocity of the spacecraft by about

WASHINGTON — NASA has selected Rocket Lab to launch the remaining four cubesats of a constellation to monitor tropical weather systems after the first two were lost in an Astra launch failure.
