Its heart, the optical bench, has now been further integrated into the core assembly of the satellite.
The optical bench of the LISA Pathfinder (LPF) mission is the super-sensitive heart of a technology demonstrator mission which will pave the way for a future spaceborne detector to measure gravitational waves. These ripples in spacetime are caused by massively violent astronomical events such as the collision of black holes and the explosion of dying stars.Optical bench

For this purpose, one laser arm of a planned large gravitational wave mission is reduced from millions of kilometres to 40cm to fit into a single spacecraft. The optical bench tested at the IGR in
It is now in Astrium Germany and firmly on course for a launch in 2015. At Astrium members of the
LISA Pathfinder is paving the way for a large-scale space mission designed to detect one of the most elusive phenomena in astronomy - gravitational waves. Extreme precision is required to detect the tiny ripples in the fabric of space and time predicted by
Gravitational waves measured by a large mission in space will allow scientists to trace the formation, growth, and merger history of massive black holes. It will also enable scientists to test General Relativity with observations, and will probe new physics and cosmology.
LPF is an ESA led mission. It involves European space companies and research institutes from
The concept and details of the optical sensing scheme for LISA Pathfinder have been developed at the
In order to build the optical bench the IGR scientists, led by Dr.
The research and development at the IGR has been funded by the
