I watched in youtube as Delta 2 rocket successfully launched NASA’s Kepler spacecraft, a mission to search for Earth-like planets around other stars. The Delta 2 XX rocket lifted off on scheduled at 10:49 pm EST Friday (0349 GMT Saturday) and injected the Kepler spacecraft into an Earth-trailing heliocentric orbit about an hour later. The spacecraft, part of NASA’s Discovery Program of relatively low-cost science missions, will monitor over 100,00- stars continuously for over three years, looking for slight, periodic decreases in brightness caused when planets orbiting the star pass through the line of sight between the star and spacecraft. I will keenly watch as Astronomers might discover planets much smaller than previously detected, including worlds with similar sizes and orbits as the Earth.
