In the early ISS planning years, ESA member states approved the Columbus Programme for 1993–1995, allowing system work to begin and setting Europe’s path toward a permanent laboratory on the station. This decision linked Europe’s future ISS research capability to long-term political and budget commitments.
As part of Europe’s broader ISS participation approach, ESA provided “Early Delivery Items” to partners and received compensation in the form of rights and hardware support for later ISS activities. This helped keep the Columbus plan viable while the station was still being redesigned and assembled.
To operate Columbus as a full-time ISS laboratory, ESA tasked DLR’s German Space Operations Center (GSOC) with building a dedicated mission control capability. This started the creation of the Columbus Control Centre (Col-CC), including the tools and teams needed to monitor systems and run experiments from Europe.
ESA and DLR inaugurated the Columbus Control Centre in Oberpfaffenhofen near Munich. The center was designed to command and control the Columbus module, coordinate European payload operations, and connect to the wider ISS control network.
ESA announced that final integration of the Columbus laboratory had been completed in Bremen, Germany. This marked the transition from a long development effort to the final pre-launch preparation phase, including shipment to the United States for launch processing.
Columbus arrived at NASA’s Kennedy Space Center (KSC) after being transported from Bremen aboard an Airbus Beluga aircraft. At KSC, the module entered NASA’s Space Station Processing Facility for checkout and preparation for a Space Shuttle assembly flight.
Before Columbus flew, the Columbus Control Centre supported and scheduled European experiments on the ISS, demonstrating it could function as an ISS control center. This operational experience helped reduce risk before Col-CC took responsibility for the new laboratory module.
The Columbus laboratory launched aboard Space Shuttle Atlantis as part of ISS assembly mission 1E. Its launch delivered Europe’s largest single ISS hardware contribution and expanded the station’s permanent research capacity.
Using the station’s robotic arm, crews attached Columbus to the starboard side of the Harmony (Node 2) module. This was a major ISS assembly milestone because it made Columbus a permanent, pressurized laboratory available for long-term research.
After initial leak checks and system hookups, the hatch to Columbus was opened and internal outfitting began. From this point, Col-CC in Germany took a central role in commanding the lab’s systems and bringing research facilities into operation.
During the STS-122 mission, astronauts installed two major external payloads on Columbus: SOLAR (solar monitoring) and EuTEF (technology exposure experiments). These payloads demonstrated that Columbus could support research both inside the lab and on external mounting points in open space.
After about a year and a half exposed to the space environment, EuTEF was removed from Columbus and brought back to Earth aboard Space Shuttle Discovery. Returning hardware allowed researchers to inspect how materials and components aged in vacuum, radiation, and extreme temperatures.
Ten years after launch, Columbus was highlighted as a long-running ISS research platform supporting multiple experiment racks and international investigations. The anniversary underscored that Columbus had moved from assembly hardware to routine science infrastructure for the station.
A new external hosting platform, Bartolomeo, was added to Columbus to expand the number of experiments that could be mounted outside the station. This marked a shift toward supporting more varied (including commercial) uses of external payload sites tied to Columbus’ power and data systems.
ESA reported that Columbus, as part of the ISS, would complete its 100,000th orbit in September 2025. The milestone highlighted long-duration operations and sustained European control and utilization of the laboratory nearly two decades after launch.
