Europe has launched the Lisa Pathfinder satellite, an exquisite space physics experiment. It will test the technologies needed to detect gravitational waves - the warping of space-time produced by cataclysmic events in the cosmos. Having such a capability would make it possible to detect the merger of monster black holes - a marker for the growth of galaxies through time. Lisa Pathfinder went into orbit on a Vega rocket from French Guiana.
It lifted away from the Kourou spaceport at 01:04 local time (04:04 GMT).
The satellite is being sent in the direction of the Sun, to a point some 1.5 million km from Earth.
The expectation is that the European Space Agency (Esa) mission will operate for about a year.
