Recently, a natural gas leak compelled NASA to evacuate hundreds of people from several Kennedy Space Center buildings, according to the AP.
The trouble occurred just one day after the Space Shuttle Discovery hit its launch pad.
NASA spokesman Allard Beutel (byoo-TEHL) explained the reason of leak to the AP and said that it happened when a backhoe struck a natural gas line.
No injuries or damages were sustained and NASA staffs have been back on the work.
Just after the leak was noticed, all the workers were emptied from several key facilities, including the Orbiter Processing Facilities, hangars housing the space shuttles Atlantis and Endeavor.
