Four external payloads (payload facilities) can be operated at the same time.The first Columbus-EPF payload facilities were the European Technology Exposure Facility (EuTEF) and Sun Monitoring on the External Payload Facility of Columbus (Solar), which were installed during the STS-122/1E mission during an extravehicular activity (EVA) by crew members. Atomic Clock Ensemble in Space and EXPORT will be delivered to the International Space Station at a later, undetermined date.In addition to structural support, Columbus can supply power and data (command) to the Columbus-EPF payloads and can poll the payloads for housekeeping (health and status) and user data.The power and data interfaces available to the Columbus-EPF payloads are directly connected to the Columbus internal distribution systems. Columbus-EPF payloads and payload facilities are controlled and commanded via Columbus using the same data links and ground segment infrastructure used for internal payloads. Each payload has a facility-responsible centre that can transmit commands and receive telemetry via the Columbus Control Centre.Columbus provides a maximum of 1.25 kW per Columbus-EPF location. Each Columbus-EPF location is connected to two 120-Vdc power feeders, each of which has a maximum allocation of 1.25 kW. Switching between the power feeders is done via the payload power switch box in Columbus and requires the power feeders to be powered down.The maximum on-orbit mass of an external Columbus-EPF payload, including the adapter plate, is 290 kg. The dimensions of a payload should not exceed 864 x 1168 x 1245 mm without the adapter plate.. }
