The search for extraterrestrial life will take another step in March, when NASA launches its Kepler satellite to systematically look for Earth-type planets orbiting other stars, according to dpa. The Kepler mission, named after the 17th century German astronomer, is to be launched on March 5 and target 100,000 stars in the Milky Way galaxy that scientists believe could have planets orbiting in a "habitable" zone, NASA scientists said Thursday. The orbiting camera will be looking for shadows moving across the stars, which would indicate planetary movement and help measure the length of the orbits.
