The Bigger Picture

Look up at Saturn (or in that general direction) and wave starting at 5:27 p.m. ET on July 19, because that's when NASA's Cassini spacecraft will be taking a picture of our home planet. If you miss that opportunity for your 15 seconds of fame, you can opt for a makeup photo, taken by the Messenger spacecraft orbiting Mercury, at 7:49 a.m., 8:38 a.m., or 9:41 a.m. ET on July 20 (story, video): http://www.usatoday.com/story/tech/2013/07/18/smile-youre-on-candid-cassini-camera/2563483/
