The Objective

The LISA (Laser Interferometer Space Antenna) mission, set to launch in 2035, is a groundbreaking space observatory designed to study gravitational waves and uncover the mysteries of the universe. Led by the European Space Agency (ESA) and OHB System AG, LISA will consist of three spacecraft arranged in an equilateral triangle, each 2.5 million kilometers apart, orbiting the Sun alongside Earth. This mission, valued at more than 800 million euros, aims to detect space-time distortions predicted by Einstein’s theory of relativity, offering unprecedented insights into cosmic events such as supermassive black hole mergers and the expansion of the universe. By using laser interferometry to measure tiny changes in distance between test masses in space, LISA will provide critical data to test physical laws and expand our understanding of gravity and the cosmos.

OHB Hellas Contributions

Building on our heritage from the PLATO mission, OHB Hellas provides the critical backbone for the LISA space segment. We manage the complex Requirements Engineering and Documentation lifecycle, ensuring seamless integration between ESA, NASA, and the international industrial consortium led by OHB System AG. Our role is vital in maintaining the technical integrity of this 2035 roadmap.
