Short answers, pulled from the story.
The Mission Control Center in Houston is named after Christopher C. Kraft Jr., a NASA engineer and manager who established the agency's Mission Control operation and served as its first Flight Director. Building 30 was officially named for Kraft on the 14th of April 2011.
Before moving to Houston in 1965, Mission Control operated from the Engineering Support Building at Cape Canaveral Missile Test Annex in Florida, about half a mile east of Phillips Parkway. That original facility, known as the Mercury Control Center through 1963, was demolished in May 2010 due to asbestos and an estimated five-million-dollar repair cost.
The Houston Mission Control Center in Building 30 first opened for operations in June 1965. The first mission it controlled was Gemini 4.
MOCR 2 was designated a National Historic Landmark in 1985 because it served as the flight control room for Apollo 11, the first crewed Moon landing. The room was later restored to its Apollo-era configuration and reopened to the public on the 1st of July 2019 after a two-year restoration effort.
CAPCOM stands for capsule communicator. The position is always filled by an astronaut, who is normally the only controller permitted to speak directly with the crew in flight. The only exceptions are the Flight Surgeon or the Flight Director, and only in an emergency.
During hurricanes, NASA can relocate Mission Control to a Backup Control Center. For Hurricane Harvey in 2017, the backup was a hotel in Round Rock, Texas. Since 2017, the designated primary backup site has been the Columbia Scientific Balloon Facility in Palestine, Texas, which was used during Hurricane Laura in 2020. For longer outages, NASA can activate the Huntsville Operations Support Center at Marshall Space Flight Center.
