Astronauts

Using resources harvested on location for habitat construction is a vital step in overcoming the prohibitive cost of transporting materials from Earth. Urine, it seems, could be part of the solution.

A few years ago, for the first time ever, astronauts ate lettuce that had been grown aboard the International Space Station (ISS). It has now been determined that the "space lettuce" was at least as nutritious as similar plants grown on Earth.

The office views are amazing and the commute's a blast ... NASA is looking for a new generation of astronauts to travel to the ISS, the Moon and maybe even Mars as part of the Artemis mission program. So scrub up your CV, have you got what it takes?

There’s only so much oxygen we can take with us to the Moon, so figuring out how to produce it there is crucial. Now, ESA researchers have created a prototype device that can make oxygen out of the most common thing on the Moon – dirt.

All sorts of health problems arise when as you take humans out into space. New microgravity simulations show that our guts can become “leaky” after a stint in space, increasing the chances of certain infections and diseases for weeks afterwards.

A new analytical tool suggests distinct microbiome changes caused by spaceflight are most likely caused by microgravity.

Red wine may have health benefits against cancer, obesity, aging, and even cavities. Now, a new study may add muscle loss to the list. In tests on rats, a Harvard team found that a red wine compound called resveratrol could help keep astronauts toned during trips in space or life on Mars.

Space travel is conducive to injuries. Now researchers from Dresden Technical University (TUD) have developed a 3D bioprinting method for use in space, creating new skin and bone tissue out of resources that might be available to astronauts.

Most oxygen in the universe isn’t in the form that we need to breathe: molecular oxygen, or O2. Now, researchers at Caltech claim to have created a reactor that can turn carbon dioxide into molecular oxygen, which could help us fight climate change here on Earth or generate oxygen for life in space.

NASA has conducted a comprehensive study comparing the genes and biology of identical twins Scott and Mark Kelly, after Scott spent almost a year in space while Mark stayed on Earth as a control. And now the results of that study have finally been released.

The lack of gravity in space means that muscles begin to waste away, and scientists have been studying these health effects on Earth with extended bed-rest experiments. In the latest, those beds will be put in a centrifuge to mimic artificial gravity, to see if that can help offset the issues.

A recent NASA-funded study has found dormant viruses can reactivate in the human body during spaceflight, presenting yet another physiological problem for scientists to solve before we journey out into deep space.
