Laser Interferometer Space Antenna (LISA)
LISA, a space-based detector with million-kilometer long arms will detect low-frequency gravitational waves that cannot be measured by ground based gravitational wave detectors.
The LISA movie
LISA will be the first observatory in space to explore the “Gravitational Universe”. LISA will complement our knowledge about the beginning, evolution and structure of our universe.

Artist's impression of a LISA spacecraft with a laser beam: The LISA mission consists of one “Mother” and two “Daughter” spacecraft orbiting the Sun in a triangular configuration. The three satellites are separated by a distance of 2.5 Mio km. The spacecraft are connected by laser beams forming the arms of a high precision laser interferometer. This interferometer senses gravitational waves by monitoring the changes in distance between free falling test masses inside the spacecraft.
