Abstract
LISA (Laser Interferometer Space Antenna) is designed to observe gravitational waves from violent events in the Universe in a frequency range from 10−4 to 10−1 Hz which is totally inaccessible to ground based experiments. It uses highly stabilised laser light (Nd:YAG, λ= 1.064 μm) in a Michelson‐type interferometer arrangement. A cluster of six spacecraft with two at each vertex of an equilateral triangle is placed in an Earth‐like orbit at a distance of 1 AU from the Sun, and 20° behind the Earth. Three subsets of four adjacent spacecraft each form an interferometer comprising a central station, consisting of two relatively adjacent spacecraft (200 km apart), and two spacecraft placed at a distance of 5x106 km from the centre to form arms which make an angle of 60° with each other. Each spacecraft is equipped with a laser. A descoped LISA with only four spacecraft has undergone an ESA assessment study in the M3 cycle, and the full 6‐spacecraft LISA mission has now been selected as a cornerstone in the ESA Horizon 2000‐plus programme.
