In celebration of the upcoming 40th anniversary of humans setting foot on the moon, hackers placed a 1/2 scale replica of the Apollo Lunar Module on the Great Dome.

While the Apollo 10 mission of May 18, 1969 didn't land on the moon, Apollo 11 mission resulted in the first humans setting foot on the moon on July 20, 1969.

The replica placed on the dome contained details such as an American flag, communications antennae, and an egress platform.

Shortly after the Apollo lander appeared, hackers also installed a large statue of Athena in Killian Court.

Some related hacks include Sputnik in Lobby 10 in 2007, the Wright Flyer on the Dome in 2003, and the NASA meatball on the Dot in 2008.
