The ponds cool the fuel - which generates intense heat - and provide shielding from radiation.

That intensity would likely swamp the radiation shielding on a typical satellite, and the authors estimate that most would be rendered inoperable within a year after the storm.

Further, study of the captured space rock could teach researchers how to efficiently extract water from asteroids a resource that could be an off-Earth source of radiation shielding and rocket fuel for journeying spacecraft.

One of the key technologies that is needed is a means to recycle water from astronauts back into a drinkable form, along with radiation shielding and developing ways of working and living in space for prolonged periods.
Trash tiles could, for example, bolster the space radiation shielding around the astronauts' sleeping quarters or perhaps a small area in the spacecraft that would be built up to serve as a storm shelter to protect crews from solar flare effects, NASA officials said.

Dennis Tito is planning an ambitious private flyby of Mars for 2018 that will carry all kinds of logistical challenges during its proposed 501-day span, not the least of which is shielding the crew from radiation without consuming valuable resources.
Honeywell began the MRAM effort in 1984 at the urging of the Department of Defense, which needed memory for satellites and long-range missiles that could withstand radiation in space without the addition of heavy shielding.
The latest problem, according to a new article in Acta Astronautica (we've really been meaning to renew our subscription), is that a space elevator would be so slow-moving (200 kph, or 124 mph) that the half-week spent in the Van Allen radiation belt would kill any living thing without proper shielding.
