NASA Retires Kepler Spacecraft
October 30, 2018
After nine years of collecting data that indicate our sky is filled with billions of hidden planets, NASA's Kepler space telescope has run out of fuel. Kepler leaves a legacy of more than 2,600 planet discoveries from outside our solar system, many of which could be promising places for life. Data from the Kepler spacecraft will continue to be mined for years to come.
