The Bell celebrates the 50th anniversary of the Apollo moon landing, and the anniversary of NASA’s Apollo 10 mission that orbited the moon, with an illuminating installation by U.K. artist Luke Jerram. Suspended from the ceiling in the museum’s Horizon Hall, the seven-meter, spherical installation is a compilation of NASA imagery, simulated moonlight, and a soundscape by composer Dan Jones. At an approximate scale of 1:500,000, each centimeter of the internally lit sphere represents five kilometers of the lunar surface. It’s the closest most of us will ever get. Special events scheduled include evening receptions with activities and talks, morning yoga sessions, a pajama party for kids, and a 5K run and Apollo-themed festival.
