LISA is the first scientific endeavor to detect and study gravitational waves from space. It's a constellation of three spacecraft that will trail Earth in its orbit around the Sun, forming an accurate equilateral triangle in space. Each side of the triangle will be 2.5 million km long (more than six times the Earth-Moon distance), and the spacecraft will exchange laser beams over this distance. The launch of the three spacecraft is planned for 2035, on an Ariane 6 rocket.

ESA’s Science Programme Committee just approved the mission and gave the go-ahead to build the instruments and spacecraft. This work will start in January 2025 once a European industrial contractor has been chosen.

This resolves as NO if the launch date is pushed beyond 2035
