The greatest hazard for humans on deep-space exploration missions is radiation. To protect astronauts venturing out beyond Earth's protective magnetosphere and sustain a permanent presence on Moon and/or Mars, advanced passive radiation protection is highly sought after.

To better understand and mitigate the health risks faced by astronauts from exposure to space radiation, we ideally need to be able to test the effects of Galactic Cosmic Rays (GCRs) here on Earth under laboratory conditions.

Space radiation is a major risk for humans, especially on long-duration missions to outer space, e.g., a manned mission to Mars.

Rotifer Studies In Space

With the spacewalk season on hold until next year, ESA astronaut Luca Parmitano took his time to prepare the orbital home for new, tiny and incredibly resistant passengers. Rotifers, commonly called wheel animals, are usually less than a millimetre in size and usually found in fresh water and moist soil.

Exposure to chronic, low dose radiation -- the conditions present in deep space -- causes neural and behavioral impairments in mice, researchers report in eNeuro.

A boiling point of 5900 degrees Celsius and diamond-like hardness in combination with carbon: tungsten is the heaviest metal, yet has biological functions - especially in heat-loving microorganisms.

The International Space Station, like all human habitats in space, has a nagging mold problem. Astronauts on the ISS spend hours every week cleaning the inside of the station's walls to prevent mold from becoming a health problem.

Earth's magnetic field shields space station crew from much of the radiation that can damage the DNA in our cells and lead to serious health problems.

Simulations with animal models meant to mirror galactic cosmic radiation exposure to astronauts are raising red flags for investigators at Georgetown University Medical Center (GUMC) about the health of astronauts during long voyages, such as to Mars.

Intense radiation could strip away the ozone layer of Earth-like planets around other stars and render them uninhabitable, according to a new study led by Dr Eike Guenther of the Thueringer Observatory in Germany.
