Solar bursts prompt station crews

A violent solar explosion sent a dangerous wave of radiation through space late Tuesday, prompting NASA to order the crews of Discovery and the International Space Station to take shelter overnight.

The solar flare erupted around 9:40 p.m., unleashing enough radiation to disrupt radio communications on Earth and in orbit while endangering astronauts circling 220 miles above the planet.

NASA flight surgeons and agency radiation experts determined that the burst of highly energetic particles approached a limit that made preventative action prudent.

Station commander Michael Lopez-Alegria and shuttle skipper Mark Polansky were told to move their crews to the most shielded areas in either spacecraft.

They include the middeck of the shuttle's crew compartment and temporary sleeping quarters in the station's U.S. Destiny science laboratory.

The back ends of the American lab and a Russian command control center at the outpost also were options.
