LISA Construction Begins

After years of research, and a completed pathfinder mission, the European Space Agency has officially begun the construction of the Laser Interferometer Space Antenna (LISA). This will consist of three spacecraft flying in formation, sending laser signals back and forth to detect passing gravitational waves - including previously undetected supermassive black hole mergers. ESA has chosen OHB System AG to construct the spacecraft, which are due to launch in 2035 on an Ariane 6 rocket.
