    Facility Overview

    • The European Technology Exposure Facility (EuTEF) provided a platform for several types of experiments or materials to be exposed directly to the space environment.
    The European Technology Exposure Facility (EuTEF) was mounted outside the Columbus module and carried experiments that required exposure to the space environment. The EuTEF was a programmable, multifunctional architecture that provided uniform interfaces for instruments. Nine instrument modules were accommodated and operated simultaneously.

    The experiments and facility infrastructure were accommodated on the Columbus External Payload Adapter (CEPA), which consisted of an adapter plate, an Active Flight Releasable Attachment Mechanism (A-FRAM), connectors, and a harness. The experiments were mounted directly on the adapter plate or on a support structure that elevated them for optimum exposure in the ram (direction of flight) and zenith directions.

    The total facility mass was about 350 kg and required less than 450 W peak. The first round of experiments for the EuTEF consisted of the following:
    • DEBris In-orbit Evaluator (DEBIE-2): Detected micrometeoroid and orbital debris

    • Dosimetric Telescope (DOSTEL): Measured the radiation environment

    • EuTEF Thermometer (EuTEMP): Measured EuTEF's thermal environment

    • Earth Viewing Camera (EVC): Served as Earth observation camera

    • Exposure Experiment (Expose): Acted as an exobiological exposure facility

    • Flux(Phi) Probe EXperiment (FIPEX): Detected atomic oxygen

    • Material Exposure and Degradation Experiment (MEDET): Examined material degradation

    • Plasma Electron Gun Payload (PLEGPAY): Discharged plasma in orbit

    • An Experiment on Space Tribology Experiment (Tribolab): Served as a testbed for the tribology (study of friction on moving parts) properties of materials
    The Mission 1E crew attached the Columbus module to the International Space Station (ISS) and powered it up. Crewmembers performing an extravehicular activity (EVA) installed EuTEF. Before EuTEF was moved, its stay-alive heaters prepared it for the unpowered 5-hour phase (the battery-powered EuTEMP will monitor the temperatures). A crewmember strapped to the Station's Canadarm 2 released the EuTEF from the Integrated Cargo Carrier by activating the Active Flight Releasable Attachment Mechanism. It was then pulled from its soft-dock magnets and hand-delivered to the Columbus External Payload Facility. Power feed 2 immediately activated to ensure the payload's survival in cold conditions.
