[Updated at 4:53 p.m. ET] NASA is investigating a possible lightning strike within one third of a mile of the space shuttle Atlantis, which is scheduled to launch for the final time on Friday.
Engineers will review data to determine if the lightning affected the shuttle or any of the launch pad's ground support equipment, according to a NASA statement.
A steady band of thunderstorms has hampered inspection teams from reviewing the facility, potentially delaying the launch, scheduled for 11:26 a.m. on Friday.
But workers on Thursday afternoon began procedures that would allow inspectors to investigate the incident for potential damage.
Currently the launch time remains unchanged, despite only a 30% chance of favorable weather, according to the statement.
Atlantis is poised to perform the last mission of the 30-year-old shuttle program. On board will be a four-person, veteran crew of astronauts, headed to the international space station with a load of supplies.
