European Technology Exposure Facility


The European Technology Exposure Facility was a payload mounted on the exterior of the European Columbus laboratory, one of the modules of the International Space Station. The facility, mounted onto the exterior of Columbus, provided a platform for multiple types of experiments and materials to be exposed directly to the harsh space environment.
.
The EuTEF is a programmable, multifunctional architecture that provides uniform interfaces for instruments. Nine instrument modules are accommodated and operated simultaneously. Each experiment is mounted on the Columbus External Payload Adapter, which consists of an adapter plate, the Active Flight Releasable Attachment Mechanism and the connectors & harness. The experiments are mounted either directly onto the adapter plate or a support structure that elevates them for optimum exposure to the ram and zenith directions.
In total, the facility has a mass of. The first set of experiments mounted to the facility included:
