eLISA for the study of gravitational waves

The scientific objective of one of the two major upcoming missions of the European Space Agency (ESA) will be the gravitational universe. This is the decision of ESA Science Programme Committee. Its name is eLISA (evolved Laser Interferometer Space Antenna) and it will be an high-tech experiment looking our universe from a new perspective. It will be a laser interferometer, such as those already existing in-ground Virgo and Ligo, but it will consist of three satellites in orbit around the Sun.
"The National Institute of Nuclear Physics welcomes this decision - says Roberto Battiston , Chairman of the INFN Committee of astroparticle physics and professor at the University of Trento - INFN supports since many years the search for gravitational waves and Lisa Pathfinder space mission in 2015 will test the technology behind eLISA." "Gravity is the protagonist of the evolution of the universe - continues Battiston - and the ESA's decision to support Elisa pointing to the direct verification of one of the most extraordinary phenomena provided by general relativity, gravitational waves ."
