History of DLR

DLR’s heritage dates back more than 115 years to the founding of Germany’s first aeronautical research organizations in the early 20th century. The organization’s roots can be traced to pioneering aviation research institutions established in 1907 and 1912, making it one of the world’s oldest aerospace research organizations. 

Following several reorganizations, the modern DLR was officially formed in 1997 through the merger of the German Aerospace Research Establishment (DLR) and the German Space Agency (DARA). Today, the organization employs thousands of scientists, engineers, and researchers at numerous research centers throughout Germany.

Major Milestones

Over more than a century of research, DLR has contributed to numerous technological breakthroughs and international space missions.

Early Aviation Research

DLR’s predecessor organizations helped establish many of the aerodynamic principles used in modern aviation, including swept-wing research that influenced the design of high-speed jet aircraft. 

Germany’s First Satellite (AZUR)

One of Germany’s first major space projects was AZUR (625 A-1), launched in 1969. Developed with NASA, AZUR studied cosmic radiation, the Van Allen radiation belts, and Earth’s magnetosphere, marking Germany’s entry into satellite-based space science. 

TerraSAR-X

In 2007, DLR launched TerraSAR-X, one of the world’s most advanced radar imaging satellites.

Operating in the X-band, TerraSAR-X provides:

• High-resolution radar imagery
• All-weather imaging
• Day-and-night Earth observation
• Disaster monitoring
• Mapping
• Military reconnaissance
• Environmental monitoring

The mission was developed in partnership with Airbus Defence and Space.

TanDEM-X

Launched in 2010, TanDEM-X flew in close formation with TerraSAR-X to create the first consistent global three-dimensional digital elevation model (DEM) of Earth’s land surface.

The mission became one of the most successful radar mapping projects ever undertaken.

Earth Observation Leadership

DLR has played a major role in European Earth observation programs, supporting missions including:

• ERS-1
• ERS-2
• Envisat
• Sentinel satellites
• TerraSAR-X
• TanDEM-X

Its German Remote Sensing Data Center processes and distributes satellite data used worldwide for environmental monitoring, agriculture, disaster management, and climate research.
