Johnson Space Center (Mission Control)

The Lyndon B. Johnson Space Center in Houston houses NASA’s Mission Control Center, the center for U.S. human spaceflight operations. During Apollo 13 the crew radioed a problem to Mission Control in Houston, a transmission that spawned the widely quoted phrase “Houston, we have a problem.” That line and variations from the mission have become a pervasive internet meme and shorthand for unexpected trouble; the exact original wording is often disputed between mission transcripts and later movie dialogue.
