European Technology Exposure Facility

The European Technology Exposure Facility (EuTEF) 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.

Each experiment is mounted on the Columbus External Payload Adapter (CEPA), which consists of an adapter plate, the Active Flight Releasable Attachment Mechanism (A-FRAM) and the connectors & harness.
