European Drawer Rack
Encyclopedia
The European Drawer Rack (EDR) is a single, six-post International Standard Payload Rack (ISPR) with seven Experiment Modules (EMs), each of which has separate access to power and cooling. A Video Management Unit sends streaming video, images, and science data to Earth via the Columbus module
's high-rate data link and can temporarily store 72 GB of video. The experiments are largely autonomous to minimize data transfer requirements, though the EDR can be operated remotely via telescience or in real time by the crew via a dedicated laptop. The EDR has two different types of EMs: the standard International Space Station locker and the standard eight panel unit International Subrack Interface Standard (ISIS) drawer.
EDR is a multi-user facility on-board the International Space Station
that accommodates a variety of science experiments. It is located in the Columbus Laboratory
module and was developed for the European Space Agency
by Alenia Spazio, a subsidiary of Thales Alenia Space
. Like other payload racks in the station, the physical characteristics of EDR conform to the International Standard Payload Rack
specification.
EDR provides accommodation for up to 3 ISIS Drawers, and 4 ISS Lockers. These standardized ECMs (Experiment Container Modules) can contain scientific experiments. EDR provides the following services to the ECMs:
The following ESA payloads are designed for use in EDR:
EDR is operated according to ESA's decentralised payload operation concept. The FRC (Facility Responsible Centre) for EDR is Erasmus USOC, located at ESTEC, Noordwijk
