The Artemis II mission will set several notable human spaceflight records. Astronauts Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen will travel farther from Earth than any human in history. They won’t land. That distinction will fall to the next mission in line in NASA’s Artemis program.

Taken together, the work shows that spaceflight can speed and then reverse blood-based aging signals through immune and methylation changes. Researchers can use that fast cycle to probe resilience and screen interventions, but solid answers will depend on bigger, longer studies.

A NASA astronaut on the ISS captured the Space Launch System rocket for Artemis 2, a mission that aims to bring four astronauts around the moon as soon as Feb. 6.

A stronauts’ bodies undergo plenty of stress beyond just the extraordinary g-forces at launch. Microgravity, cosmic radiation, biological clock disruptions, and more all take a toll on space travelers. Now, new research is shedding light on how these invisible stressors can prematurely age astronauts—and how they can bounce back.

Spaceflight takes a physical toll on astronauts, causing muscles to atrophy, bones to thin and bodily fluids to shift. According to a new study published in the journal PNAS, we can now add another major change to that list.

Blue Origin launched six people to suborbital space today (Jan. 22). It was the 17th human spaceflight for the company, which was founded by Amazon's Jeff Bezos.

The first crewed spaceflight of NASA’s Artemis program will break records, achieve historic firsts, and pave the way for America’s return to the Moon.

Microorganisms live in biofilms—the equivalent of microbial "cities"—everywhere on Earth. These city-like structures protect and house microbial communities and play essential roles in enabling human and plant health on our planet.

Space apparently changes your frame of mind in more ways than one.

A new study reveals spaceflight physically shifts astronauts’ brains inside the skull, with changes lasting months after return, raising new questions about microgravity’s hidden effects on human health.

WASHINGTON (Reuters) -New research has identified yet another way that spaceflight tampers with the human body. A study involving samples flown on four SpaceX resupply missions to the International Space Station has revealed that space travel accelerates ...
