A 6000 kilometer area between the two Van Allen belts was previously thought to be a "safe zone" where lighter, smaller, cheaper, and less heavily shielded satellites could operate. But a discovery with a research satellite has found that during severe solar storms high energy particles spill into the zone where it was hoped that cheap satellites with little shielding could operate.
A region of space around the Earth that was previously thought to be free of radiation actually teems with high-energy charged particles during solar storms. The news may dash scientists' hopes of sending up ultra-cheap, lightweight satellites that do not carry much protection against radiation.
