The joint ESA/NASA mission LISA is a space-borne interferometer to
detect and observe gravitational wave. The scientific goals of LISA
are to determine the role of massive black holes (MBH) in galaxy
evolution, to perform precision tests of General Relativity, determine
the poupulation of ultra-compact obejcts in the galaxy and to probe
the physics of the early Universe.
The LISA mission was selected as an ESA Cornerstone and is included in NASA's 'Beyond Einstein' initiative, with a launch in the 2012/2013 time frame.

The GEO600 laser interferometric gravitational wave detector is approaching the end of its commissioning phase which started in 1995.
During a test run in January 2002 the detector was operated for 15 days in a power-recycled michelson configuration. The detector and environmental data which were acquired during this test run were used to test the data analysis code. This paper describes the subsystems of GEO600, the status of the detector by August 2002 and the plans towards the first science run.
