ESA's Scientific Program Committee has adopted the LISA mission, giving the go-ahead for construction of the instrument and satellites. For the first time, LISA will observe the Universe through gravitational waves from space.
ISA (Laser Interferometer Space Antenna), the European Space Agency's large-scale mission to explore the Universe by observing the many sources of gravitational waves, was adopted on Thursday January 25 by ESA's Scientific Programs Committee, meaning that the concept and technology are recognized as sufficiently advanced for construction of the instrument and satellites to begin.
