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
''Columbus'' is a science laboratory that is part of the International Space Station (ISS) and is the largest single contribution to the ISS made by the European Space Agency (ESA).
Like the ''Harmony'' and ''Tranquility'' modules, the ''Colum ...
'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.
Overview
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

. These standardized ECMs (Experiment Container Modules) can contain scientific experiments. EDR provides the following services to the ECMs:
* Stowage space
* Power supply (28 V DC, 120 V DC)
* Low Rate telecommand/telemetry (19.2 kbit/s
RS-422)
* Medium Rate telecommand/telemetry (10 Mbit/s
Ethernet)
* High Rate telemetry (32 Mbit/s
SpaceWire)
* Analogue video acquisition (
NTSC)
* Discrete commanding, monitoring and temperature monitoring services
* Air cooling
* Water cooling
* Gaseous Nitrogen supply
* Vacuum service
* Waste gas service
* Timeline service
* Ancillary data and time services
* Laptop crew interface
The following ESA payloads are designed for use in EDR:
