Artist's concept of the LISA mission. LISA needs to measure the distance between proof masses, separated by five million kilometers, with an accuracy of 10 picometers (10 millionths of a micron).
LISA to attempt gravity wave detection
Gravitational waves passing through the solar system will generate small changes in the distance between three spacecraft in an equilateral formation, 5 million kilometres apart.
The Laser Interferometer Space Antenna, will observe gravitational waves from very massive black holes found in the centers of many galaxies.
Gravitational waves are one of the fundamental building blocks of our theoretical picture of the universe, yet they have not been observed.
