The next astronauts to travel around the moon seem plenty fit to make the trip. The four astronauts who will fly on NASA’s Artemis 2 mission recently passed the “Bobby and Pete Challenge,” performing 50 pull-ups and 100 pushups in less than 10 minutes. The quartet — NASA’s Victor Glover, Christina Koch and Reid Wiseman, and Jeremy Hansen of the …

Scientists have developed a more efficient way to generate oxygen for astronauts that could help with future missions into deep space. Current life-support systems such as those on the International Space Station (ISS) rely on bulky centrifuges to separate the oxygen and hydrogen bubbles created when water is split by electricity, a process known as electrolysis. On Earth, bubbles rise …

Scientists are calling attention to an extremely common health problem that’s been making astronauts uncomfortable: sinus issues. Researchers from Houston Methodist hospital’s Department of Otolaryngology – Head and Neck Surgery reported the results of their recent study that probed whether astronauts experience sinonasal issues, which include common symptoms such as nasal congestion and pressure or pain in the face, while …

As the April 2026 launch date gets closer and closer for NASA’s Artemis 2 moon mission, its four astronauts are working to ready themselves for the historic event. What is it? At NASA training centers, astronauts use simulators, mockups, models and even inflatable moons to hone their skills for upcoming missions. In a recent X post, NASA’s Goddard Space Flight …

Over half a year into Donald Trump’s second term, NASA still doesn’t have a long-term head. That leadership vacuum comes as the space agency is staring down the barrel of some devastating cuts to its science budget, with the White House betting its future on space exploration alone. The chaos has raised serious questions about NASA’s ambitious plans to return …

Chinese astronauts added more debris shielding to the Tiangong space station during a 6.5-hour spacewalk on Friday (Aug. 15), according to state media. Two astronauts from the three-person Shenzhou 20 mission ventured outside Tiangong to do the spacewalk, which concluded Friday at 9:27 a.m. EDT (1447 UTC, or 10:47 p.m. in Beijing). It was at least the second effort for …

In space, even breathing can become a mission challenge. A new analysis of nearly two decades of medical logs from 71 International Space Station (ISS) crew members finds that sinus and nasal issues are among the most common health complaints in orbit – affecting 85 percent of astronauts. Most dealt with at least one bout of congestion, and those who …

“In space the sun is really harsh, it feels as if it’s piercing through your eyes,” says Koichi Wakata, an astronaut and the Chief Technology Officer for Axiom Space. “We need an exceptional visor system to protect [our] eyes and [offer] maximum visibility to enable [astronauts] to work in the challenging lunar environment.” The Texas-based …

As NASA embarks on longer-duration space missions, including the goal of sending humans to Mars, the challenge of maintaining astronaut health far from Earth becomes ever more pressing. In collaboration with Google, NASA is developing a cutting-edge AI medical assistant designed to help astronauts diagnose and treat medical conditions autonomously when communication with Earth is unavailable. This initiative is part …
