Surviving bacteria in space
... before venturing too far This suggests that the adhesion machinery was either aborted by the ionising radiation or that the ionising stress conditions rearranged the cellular priorities. The bacteria could, for example, prepare to ‘escape’ from...

Spaceflight and the radiation problem
... Moon or another planet, we must pass through the Van Allen belts, beyond which the background dose of ionising radiation increases dramatically. So, to understand the risks involved for the crew, we must also consider the likely duration...

Nutritional issues on interplanetary spaceflights
...in terms of essential nutrients to ensure preservation of the crew members’ health and performance under exposure to high levels of ionising radiation and other unfavourable factors during missions to the Moon and deep space. Since the 1960s, Russian...

Radiation-loving fungus could protect astronauts from cosmic rays
... that suffered a meltdown in the 80s and on the exteriors of spacecraft in low-Earth orbit, where ionising radiation is also high. How do these radiation-loving organisms survive? The fungus is packed with large amounts of the pigment melanin, which...

Best time for a human Mars mission? During a solar maximum, new study says
... a typical spacecraft or the skin of an astronaut. To put it in perspective, if a human receives one Milli-Sieverts (mSv) of ionising radiation, that is the equivalent of being exposed to about three chest x-rays. Astronauts on the other hand can...
