Astronauts

Previous research has shown that microgravity affects the immune system but what about the stem cells that build it? Until recently, no one had tested how spaceflight affects the aging and fitness of these crucial cells, and the news is not so great.

If you've ever looked into the living conditions of astronauts in space, you probably know they make do with spartan arrangements, including mostly rehydratable meals. Fermentation could help with making a wider variety of flavorful foods available.

In the not-too-distant future, astronauts could be drinking water harvested from their own urine, courtesy of a Dune-inspired system integrated into their spacesuit. If nothing else, it should certainly beat just peeing into a diaper.

Bridging fashion and functionality, SpaceX has revealed what its astronauts will be wearing on the first-ever private spacewalk in 2024. In a new video, the company details the features of the suit that will be space-tested on the Polaris Dawn mission.

In order to survive long trips to other planets, astronauts are going to have to eat more than just easily-stored TV dinners and ramen noodles. With that fact in mind, scientists recently created what they determined could be the ideal fresh-food meal for space travelers.

Space agencies often put space-suited astronauts in swimming pools, so they can learn to perform tasks in an outer-space-like environment. The UHAB is intended to take things further, by simulating the habitats in which astronauts may someday live.

A resupply mission to the ISS is planned for next week, which will include a special delivery for Andreas Mogensen in the shape of a Vive Focus 3 VR headset intended to help the Danish astronaut cope with the stress of working in space.

The unique perspective just a few astronauts have ever seen of Earth from outer space, and the way in which it impacts them, is known as the Overview Effect. Now, specially built theaters and a new film will bring the same experience to the masses.

A new study has found that the rigors of space travel alter the expression of an astronaut’s genes, leading to a compromised immune system that may make them vulnerable to infection, especially when they first return to Earth.

In cramped spacecraft or space stations, there isn't room to store multiple robots that are each designed for a specific task. The Mori3 system was designed with that fact in mind, as it can be used to create different types of robots as needed.

Water on the Moon isn't kept in convenient reservoirs, it’s locked away in the lunar soil. Now, a team of scientists has found that thirsty astronauts could one day refresh themselves fairly easily – by throwing a cup of Moon dirt in the microwave.

Space travel places great stress on the mind and body. With an eye on its implications for future space travel, a new study is the first to examine how flight involving exposure to significant changes in g-forces impacts the functioning of pilots' brains.
