Lunar Lander
Pearlington, Mississippi
A Lunar Lander -- formerly known as a Lunar Excursion Module, or LEM -- is on display just across the Mississippi-Louisiana state line. It's a nod to NASA's "Stennisphere" Space Center, which is off in the woods nearby -- the place where the Saturn V rockets were test-fired during America's mad race to the moon.
This Lander-trainer was the only one that the crew of Apollo 13 ever used as a LEM, since they never made it onto the moon. Fred Haise, who was the LEM pilot (and who was played by Bill Paxton in the Apollo 13 movie), was from Mississippi, and returned to this Lunar Lander in 2000 to leave his signature and moon boot prints in cement -- a consolation prize, since the Apollo 13 near-disaster meant that Fred never got the opportunity to leave his footprints on the real Moon.
In 2019, just in time for the 50th anniversary of the moon landing, the Lunar Lander was moved from its formerly free spot outside the Mississippi Welcome Center, to a you-have-to-pay-to-see-it spot inside the compound of the neighboring Infinity Science Center.
