NASA IS ABOUT TO BUZZ EUROPA: For the first time in more than 20 years, NASA is about to buzz Europa. On Sept. 29th, the Juno spacecraft will fly only 222 miles above the frozen surface of Jupiter’s ocean moon looking for new fissures and plumes of water vapor. Of special interest is an area of chaos terrain called “Annwn Regio,” which will be right under Juno’s cameras. Full story @ Spaceweather.com
