The evolution of mission control in space has been traced back to the origins of Nasa's mission control room, which is responsible for the success or failure of space missions. The original mission control centre, housed in Building 1385 at Cape Canaveral, Florida, was designed to oversee America's Project Mercury flights and early two-man Gemini missions in the early 1960s. The Mercury Control Center, which became the template for every mission control since, was also the model for every other mission control. The main screen featured a mechanical capsule, which mimicked the flight of the spacecraft, and all decisions were overseen by a flight director. The new mission control rooms were built at the new Manned Space Center (later renamed the Johnson Space Center) for the Apollo missions to the Moon. In the 1960s, mission controllers were astronauts themselves, often known and trusted by colleagues and familiar with the spacecraft. The first mission control officer to work in the mid-1960s was Poppycutt, who joined Nasa as one of its first employees in 1958 and later oversaw the first manned flight around the Moon flight. The current mission control chief is now being led by Glynn Lunney, who oversaw the Space Shuttle programme.
