The traveling exhibit, called "Destination Moon: The Apollo 11 Mission," will reach four US cities in 2018 and 2019, the lunar mission's 50th anniversary year. All told, the display will include the space capsule, along with other "one-of-a-kind artifacts." The exhibition's locations and dates are as follows:

Space Center Houston -- October 14, 2017 to March 18, 2018

St. Louis Science Center -- April 14, 2018 to September 3, 2018

Senator John Heinz History Center, Pittsburgh -- September 29, 2018 to February 18, 2019

The Museum of Flight, Seattle -- March 16, 2019 to September 2, 2019

Once the module is off the road, it will return to its home at the National Air and Space Museum in Washington, DC. There, it will be part of a permanent "Destination Moon" exhibit, which opens in 2020 and will explore humanity's relationship with lunar travel from ancient times to today.

The space capsule isn't exactly easy to transport or host: Smithsonian Institution Traveling Exhibition Service project director Kathrin Halpern told NPR that the module weighs over 13,600 pounds. She added that for these and other reasons, this tour is "likely a once-in-a-lifetime opportunity" to see this historic spacecraft outside of Washington, DC. So enjoy it while you can, since it's not a giant leap to say it will be awhile before Apollo 11 leaves the Smithsonian museum again.
