Yesterday National Geographic unveiled an exclusive video, “Secrets of Google’s 3-D Mars, Moon“. The video offers tips on getting the most of Google Earth’s Space features, and information on little known features found within the application. Featured in the video are two former NASA scientists who now work for Google: Michael Weiss-Malik, who is the Product Manager of Mars in Google Earth, and Noel Gorelick, a Lead Engineer in the same project.
