Like the Oval Office, or the Assembly Room of Independence Hall, mission control is a distinctly American room — one so ingrained into culture that to say its name is to conjure it crisply in the mind, as though you had been there, even worked there. And the restoration was completed in a way that is true to its place in the American historical imagination.

Four long rows of pale green consoles fill the room. There are white panels overhead and new beige carpet below. Lights dance purposefully on the consoles, with each one playing Apollo-accurate video broadcasts as would have been seen at the time of the moon landings, or displaying grids of numbers and prehistoric computer code. On four giant displays in the room’s front are maps, matrices and astronaut positional plots.

On the consoles are the objects seen in photographs from the Apollo era. Ashtrays and coffee cups, staplers and stopwatches, pens and pencils, headsets and rotary dial phones. There are mission control manuals three inches thick and canisters for pneumatic tubes. Binders and eyeglasses and cigar boxes sit next to cans of RC Cola and packs of Winston cigarettes. The room is a museum piece, and yet it is alive, as though engineers stepped out briefly but would be right back. Every item is authentic, painstakingly researched from grainy photographs.

“It was a herculean effort by the team to really pull off what we pulled off in that room today,” said Jennifer Keys, the project manager of the restoration team.

Ceiling tiles that matched the originals were eventually recovered from a lobby phone booth elsewhere at the Johnson Space Center. Preserved wallpaper was discovered behind a fire extinguisher. All had to be meticulously matched or fabricated identically. Original paint was found for the consoles. And across those consoles, the artifacts of a time gone by.

“We tracked things down on eBay, from people’s donations — whatever we could scrounge up,” Ms. Keys said. “We did a scavenger hunt across Johnson Space Center to find things like trash cans, chairs and binders.”
