Background
Mission Control is the Christopher C. Kraft Jr. Mission Control Center at NASA Johnson Space Center in Houston, Texas. It has directed every crewed American spaceflight since Gemini 4 in 1965, including all Apollo lunar missions, the Space Shuttle programme, International Space Station operations, and now the Artemis campaign. The facility houses multiple flight control rooms, each staffed by specialist console operators who monitor spacecraft systems, crew health, trajectory, and communications in real time.
For Artemis II, Mission Control coordinates the flight director team managing Orion from launch through lunar flyby and splashdown. The Space Radiation Analysis Group (SRAG) operates from a dedicated console position, providing real-time radiation dose assessments and go/no-go calls for crew activities. During the April 2026 solar storm, SRAG operators at this console made the decision calls that shaped crew exposure management throughout the transit.
The centre runs 24 hours a day during crewed missions, with three shifts of flight controllers. Its authority over mission decisions, established after the Apollo 1 fire, means the flight director can override any recommendation from any source, including NASA headquarters, when crew safety is at stake.
