	The worst part of the storm lasts for several hours, so habitats and space craft will likely be equipped with a small [[Storm shelter]] with high radiation protection.

The crew will hide inside during the worst of the storm.

			Note that low levels of radiation spread over a long time, is less dangerous than the same amount of radiation in a short amount of time. This makes solar storms far more dangerous than the low level radiation levels that trickle in from [[Cosmic radiation \|Cosmic Rays]].

	Occasional [[Solar flares\|solar flares]] produce particularly high doses. Some SPEs were observed by [[MARIE]] that were not seen by sensors near Earth due to the fact that SPEs are directional. Astronauts on Mars could be warned of SPEs by sensors closer to the Sun and presumably take shelter during these events. This would imply that an [[Early warning system (solar radiation)\|Early Warning System]] (possibly a network of sensors in orbit around the sun or a single sensor in [[Lagrangian point]] L1) might be needed to ensure all SPEs threatening Mars were detected early enough.
