NASA's Kepler telescope wakes up, starts planet hunt again
NASA's planet-hunting Kepler space telescope has woken from its "sleep mode" and begun collecting science data to hunt for planets, the US space agency said on Wednesday. In July, NASA placed the spacecraft, with 2,652 confirmed planets, in a hibernation-like state to download the data collected in its latest observation campaign. The space telescope was originally launched in March 2009.
