100 years after it was predicted, the Europe will try to test the theory of gravitational waves of Albert Einstein. The European Space Agency (ESA) will launch on Wednesday from the Kourou base in French Guiana, a satellite that could lead, eventually, to allow the creation of a space observatory in charge of detecting these famous waves in propagating in the universe, would swing space-time.
Lisa Pathfinder is a mission of the European Space Agency (ESA)
Lisa Pathfinder mission the European Space Agency (ESA) intended to prepare the way for a future space observatory to detect the famous gravitational waves theorized by Albert Einstein. For his sixth mission, the rocket was to take off from the Guiana Space Centre Wednesday at 1:15 hours Kourou (4:15 GMT, 5:15 Paris time).
But hours before the launch, teams detected a problem the thermal behavior of the motor of the upper stage of the Vega launcher, told AFP Arianespace, the French company responsible for launch services. The satellite is stabilized and total security configuration, said Arianespace. The reservoirs of the upper floor – the fourth – are filled but that does not pose a problem, adds the company
The teams are working on this technical problem and a review of the results will be held on Wednesday to decide. if a launch is possible Thursday, said Arianespace in a statement. Built under the project management of Airbus Defence & amp; Space, the satellite has a takeoff weight of 1,900 kilos. It consists of a science module and a separate propulsion module.
Once launched, it is expected that Lisa Pathfinder began a long journey that will take him through a series of maneuvers, on its operational orbit about 1.5 million km from Earth. There he will test technologies to detect gravitational waves.
A proof of the existence of these gravitational waves
A hundred years ago, Einstein, the famous physicist, established that under the effect of gravity, the material moving curve spacetime. It triggers waves that will move in space as do the wrinkles caused to the surface of the water by a falling stone.
observatories including the United States and Italy actively seeking direct evidence of the existence of these gravitational waves, extremely low.
Having an observatory in space will see the great mass movements in the Universe, the very event such as a violent collision of galaxies and the merger of two black holes, according to the French physicist Pierre Binetruy of the University Paris-Diderot.
