For years, we’ve wondered if there was intelligent life on the Red Planet. If there is, it looks like Google could be the first to discover it. With the assistance of NASA scientists, the Internet goliath was able to create an interactive map of Mars, producing three imagery views (visible, infrared, and elevation), as well as 3D renderings of the terrain. Other standout features include watching orbital tracks of spacecraft in real-time and viewing panoramic images taken by robotic rovers. Hey, self-proclaimed “armchair specialist” David Martines says he accidentally found a space station on the planet that he thinks was once inhabited by humans or aliens. So who knows what we'll discover.
