NASA introduced in December 2017 a mission concept to launch an interstellar probe by the year 2069 to search for biosignatures on planets around the stars in the Alpha Centauri system.[1][2] The mission concept is as yet not funded, unnamed and the technology to get there does not exist yet.[3]

A preliminary mission concept suggests using solar sails[4] propelled by high energy lasers to increase propulsion.[4] The proposed launch would be on the 100th anniversary of the Apollo 11 mission.[5]
