Kranz led the earliest missions to the moon, including Apollo 11 and Apollo 13, and says he wants the room to inspire American students to study science and technology.
These works make apparent how singular an achievement America's moon landing was — and show that half a century later we're still grappling to understand its long-term meaning.
A fictitious asteroid is the focus of a realistic exercise, as experts at the Planetary Defense Conference run through how the Earth would respond to news of a looming asteroid strike.

"That is a terrible, terrible thing to create an event that sends debris in an apogee that goes above the International Space Station," NASA Administrator Jim Bridenstine said.
A team led by an undergraduate student at the University of Texas, Austin, has found two new planets by using artificial intelligence to sift through data from NASA's planet-hunting Kepler telescope.
Astronauts in the station opened Crew Dragon's hatch and entered the spacecraft on Sunday, in a significant moment for both Elon Musk's company and the future of commercial space exploration.
For years, NASA has had to rely on Russian vehicles to get astronauts to the International Space Station. That could soon change if the flight test of SpaceX's Crew Dragon capsule succeeds.
As the 50th anniversary of the Apollo 11 lunar landing nears, some say the site of the first footprints on the moon should be protected. But historic preservation off our planet is unprecedented.
Kindergartners from Georgetown Day School in Washington D.C., help NPR's Lulu Garcia-Navarro field questions to McClain, who's an astronaut serving on the International Space Station.
NASA's six-wheeled rover landed on the red planet in January 2004 for what was billed as a 90-day mission. The plucky robot was still going until a dust storm on Mars last summer killed it.
The last five years are also the five hottest years on record for average global temperature, according to scientists from NASA and the National Oceanic and Atmospheric Administration.
A mini biosphere was sent up in China's Chang'e-4, which landed on the far side of the moon in early January. Photos show the small, green shoot of a cotton plant in a container aboard the spacecraft.
