In 1972, Apollo astronauts narrowly escaped a potential catastrophe. On August 2nd of that year, a large and angry sunspot appeared and began to erupt, over and over again for more than a week, producing a record-setting fusillade of solar proton radiation.

The Phantom Torso is back, and he has quite a story to tell.

A stray bullet rips through the command center, blowing holes in vital equipment and damaging the data archives. Repair teams spring into action. The damage must be patched up quickly. This is a drama that unfolds every day inside the cells of astronauts.

A scientist using the Solar and Heliospheric Observatory (SOHO) has found a way to forecast solar radiation storms. The new method offers as much as one hour advance warning, giving astronauts time to seek shelter.

NASA is returning to the Moon -- not just robots, but people. While scientists were hard at work last week planning for this journey, the biggest solar proton storm in 15 years erupted. Researchers discuss what it might have done to human settlers on the Moon.
