Superconductors - key to unlocking high power space missions
...dangerous space radiation environment. Astronauts are exposed to radiation originating from the solar wind, gamma rays, and cosmic rays. Considering mission transits on the order of months, such exposure is a significant threat to crew safety and can...

Ready for Mars? From Mars-500 to zero-gravity medical issues
... the astronauts’ exposure to dangerous ionising radiation will occur. Solar flares, coronal mass ejections (CMEs) and cosmic rays will threaten the astronauts’ acceptable radiation level, with the increased risk of cancer occurring. Measurements made...

Terraforming Mars: from CFCs to Total Recall
...lifestyle is actually sustainable, most notably because of the high flux of ionising radiation (galactic and solar cosmic rays) incident on the surface of Mars. Such radiation is almost entirely blocked on Earth by the combination of Earth’s magnetic...

Blueprint for NASA’s journey to Mars
... an excellent storm shelter for Solar Particle Events, and a partial but significant attenuation of the galactic cosmic ray environment during sleep and rest periods. Orion is also designed to function as a radiation shelter. An artist’s rendering...

Planetary nebulae may hold clue in search of helium-3
... 3He and release it to the interstellar medium but that it is destroyed via processes such as spallation from cosmic rays. At present, this latter theory is totally speculative and has yet to be tested, so it is unknown as to whether this mechanism...
