WASHINGTON (AP) — Some of the most iconic artifacts of aviation and space history will be getting an updated display for the 21st century, with the Apollo moon landing as the centerpiece.

For the first time since its 1976 opening, the Smithsonian’s National Air and Space Museum plans to overhaul its central exhibition showing the milestones of flight. The extensive renovation announced Thursday will be carried out over the next two years with portions of the exhibit closing temporarily over time, said Museum Director J.R. “Jack” Dailey.
