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. The mission concept is as yet not funded, unnamed and the technology to get there does not yet exist. A preliminary mission concept suggests using solar sails propelled by high energy lasers to increase propulsion. The proposed launch would be on the 100th anniversary of the Apollo 11 mission.
