NASA's Lunar Lander exhibit is located at the Mississippi I-10 Welcome Center in Hancock County, Miss., just west of Bay St. Louis and 45 miles east of New Orleans on I-10 at Exit 2. The exhibit features a 30-foot-tall replica of a Lunar Lander used as a trainer by the Apollo 13 astronauts. Apollo 13 astronaut and Mississippi native Fred Haise left space-boot prints and signature in concrete at the base of the exhibit.
