NASA’s Apollo 11 space capsule “Columbia” took astronauts Neil Armstrong, Buzz Aldrin and Michael Collins to lunar orbit and safely back home in July 1969. The fiftieth anniversary of that trip is coming up soon, so the Smithsonian’s National Air and Space Museum is going to put the 13,600 pound capsule on display in four major U.S. cities starting late this year and continuing into 2019. This article at NPR has the story, the cities and the dates. (Image credit: Smithsonian.)
