ESA's Columbus Control Centre (COL-CC) is located at the German Space Operations Centre of the German Space Agency (DLR), in Oberpfaffenhofen, near Munich in Germany. This centre is operational 24 hours a day, seven days a week.
COL-CC controls and operates the Columbus laboratory and is in close contact with the ATV Control Centre in Toulouse, the Mission Control Centre in Houston (MCC-H), USA, which has overall responsibility for the ISS, together with the Mission Control Centre in Moscow (MCC-M). In addition, Col-CC coordinates operations with the ISS Payload Operations and Integration Centre at the Marshall Space Flight Centre in Huntsville, Alabama, USA, which is responsible for operating European experiments (payloads).
All the ground services for Colombus are provided by Col-CC. This includes communication services (voice, video and data) to the sites where ISS users are located, to the ATV-Control Centre, to the European Astronaut Centre (EAC), to industrial support sites and to the ESA management site at ESTEC.
