If space shuttle Discovery is unable to land at Kennedy Space Center in Florida on its first attempt this evening, residents along the Mississippi Gulf Coast should hear a double sonic boom about 7:25 p.m. as the vehicle makes its second landing approach to the site.
The shuttle is scheduled to conclude its STS-128 mission to the International Space Station with a 6:05 p.m. CDT landing at Kennedy. However, if that attempt is waved off, the shuttle will make a second attempt at 7:42 p.m. at Kennedy.
On the second attempt, residents would be able to hear the shuttle's signature double sonic boom as the vehicle flies over the Mississippi Gulf Coast about 7:25 p.m.
