European Drawer Rack (EDR) - 08.20.14
ISS Science for Everyone
Science Objectives for Everyone
The European Drawer Rack is a multidisciplinary facility that supports as many as seven modular Experiment Modules (EMs). A payload may be composed of several EMs. Each payload has its own cooling, power, and data communications as well as vacuum, venting, and nitrogen supply, if required.

Previous ISS Missions
- The European Drawer Rack (EDR) provides housing for smaller experiments in the International Space Station (ISS) Columbus module, allowing more research to be performed on the ISS.
- The EDR provides a low-cost location for compact, low-mass experiments that would be far too small to travel in a standard payload rack.
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. The European Drawer Rack (EDR) fills one rack in the Columbus module. Payloads are largely autonomous. The EDR provides cooling, power, and communications equipment used to transmit data to Earth. Data is sent via the Video Management Unit and the Rack Interface Controller to the Columbus sending module and then to Earth. Each drawer has its own air cooling system as well as access to water cooling, vacuum, vents, and nitrogen, if necessary.
- The European Drawer Rack (EDR), including the electronic unit of the Protein Crystallization Diagnostics Facility (PCDF), was installed in the Columbus module prior to its launch. Other drawers and lockers were filled with experiments on orbit. During launch, the four EDR lockers were used for stowage of EDR tools, PCDF umbilicals, and European payload laptops.
- The EDR experiments can be operated with telescience or run autonomously.
