Yeah, the Shuttle's Probably Not Lifting off Tomorrow

NASA says the lightning came within a third of a mile of the launch pad. NASspaceflight.com is keeping a running account of preparations, and it notes the lightning strike "was VERY powerful at nearly 70,000 amps (realize your house uses about 200 amps and most lightning strikes are 20-30,000 amps.)"

Chris Bergin, managing editor of the site, says "Confirmed lightning strike at the pad, which requires data reviews by all affected systems -- engineering. Already in work."

Even if the reviews go well, the bad weather is predicted to still be around the area on Friday.
