These are fun.
Going boldly: Behind the scenes at NASA’s hallowed Mission Control Center – Ars Technica: HOUSTON, TEXAS—Astronauts have been saying “Houston” into their radios since 1965. The callsign refers in general to the Johnson Space Center in Texas, and the people who answer to it sit in the Mission Control Center, located in Building 30 near the south end of the The Lyndon B. Johnson Space Center (JSC) campus. “Mission Control” has been the subject of movies, television shows, and documentaries for decades. It’s usually depicted as a bustling room filled with serious folks in short-sleeved white shirts and skinny black ties who shout dramatically about damaged spaceships while frantically pressing buttons on chunky 1960s control consoles. What is it really like, though, to sit at one of those consoles? What do all of those buttons do?
Apollo Flight Controller 101: Every console explained – Ars Technica: But Ars readers love space, and there was so much extra information that I couldn’t sit on it. So this is a station-by-station tour of Historical Mission Operations Control Room 2, or “MOCR 2.” As mentioned in the feature, MOCR 2 was used for almost every Gemini and Apollo flight, and in the late 1990s was restored to its Apollo-era appearance. You can visit it if you’re in Houston, but you won’t get any closer than the glassed-in visitor gallery in the back, and that’s just not close enough. Strap yourselves in and prepare for an up-close look at the MOCR consoles, Ars style.
