Laser Interferometer Space Antenna (LISA) Mission [720p]

The Laser Interferometer Space Antenna (LISA) is a joint NASA-ESA project to develop and operate a space-based gravitational wave detector sensitive at frequencies between mHz and 0.1 Hz. LISA detects gravitational-wave induced strains in space-time by measuring changes of the separation between fiducial masses in three spacecraft 5 million kilometers apart. LISA will discover many extraordinary astrophysical sources: tens to hundreds of inspiraling and merging massive black hole binaries out to a red
