(Newser) – NASA has cleared the Space Shuttle Discovery and its crew of seven to launch tomorrow, as long as a slight chance of lightning doesn't delay fueling efforts, reports Space.com. NASA won't fuel the spacecraft—preparing for a 13-day resupplying mission—if there is a 20% or greater chance of lightning within five miles. So far, skies are expected to be clear.
