Mission Control recognizes a half-century of human spaceflight leadership from Houston today, as it continues to support 24/7/365 operations in support of the International Space Station​ and prepares for the future of human exploration through the cosmos. The first spaceflight operated from Mission Control, Houston, was the Gemini IV mission launched on June 3, 1965, a flight that included the United States’ first spacewalk. #missioncontrol #MCC50th #space #spacestation #NASA
