LISA Pathfinder, formerly Small Missions for Advanced Research in Technology-2 (SMART-2), was an ESA spacecraft that was launched on 3 December 2015 on board Vega flight VV06.[3][4][5] The mission tested technologies needed for the Laser Interferometer Space Antenna (LISA), an ESA gravitational wave observatory planned to be launched in 2035. The scientific phase started on 8 March 2016 and lasted almost sixteen months.[6] In April 2016 ESA announced that LISA Pathfinder demonstrated that the LISA mission is feasible.

The estimated mission cost was €400 million.[7]
