Both types of gravitational wave detector, the resonant detectors and the laser interferometers, are starting to reach very interesting sensitivity levels and the chances of really measuring gravitational waves are increasing rapidly. At the end of this year, the first spherical detector MiniGRAIL will be ready for long term data taking and sharing the data with the other groups.
