NASA may send probe to nearest Earth-like planet in 2069
NASA is reportedly planning to send a probe to the nearest star system Alpha Centauri to study a potentially habitable exoplanet Proxima b. The mission is timed around the 100th anniversary of the first-ever manned moon landing. Being 4.4 light-years away, a spacecraft travelling at one-tenth the speed of light would take 44 years to reach Alpha Centauri.
