Astronomy:2069 Alpha Centauri mission

Short description: NASA concept for uncrewed probe - possibly a light sail
An artist's depiction of a solar sail.

In December 2017, NASA released a mission concept involving the launch, in 2069, of an interstellar probe to search for signs of life on planets orbiting stars in and around the Alpha Centauri system.[1][2] The announcement was at the annual conference of the American Geophysical Union.[3] The mission (proposed in May 2016[4]) remains a concept, and as such, has no name or allocated funding.[5]

A preliminary mission outline suggests the use of 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.[6] The spacecraft would reach Alpha Centauri by the year 2113, 44 years after its launch travelling at 10% of the speed of light.[3]
