Observing Einstein's Gravitational Waves: "The LISA mission is one of the most ambitious ever undertaken: positioning and flying three spacecraft in a triangular formation, 5 million kilometres apart. The constellation will orbit the Sun, following the Earth at a distance of 50 million kilometres so as not to be perturbed by its gravity.

Infrared lasers will be beamed between the spacecraft, arriving on small 2-kilogram proof masses, 4-centimetre cubes made of gold and platinum."
