Google Earth now allows exploration of oceans, Mars

Google Inc. has launched a new version of its Google Earth software that allows users to explore the oceans, view images of Mars, and watch regions of the Earth change over time. The new features mark a significant upgrade to Google Earth, a popular software program that provides access to the world’s geographical information through digital maps, satellite imagery, and the company’s search tools. Google Earth 5.0 was unveiled at the California Academy of Sciences in San Francisco, where former Vice President Al Gore, singer Jimmy Buffet, and others spoke about its capacity to educate the public about global warming, ocean acidification, and other threats to the planet. “This is an extremely powerful educational tool,” said Gore, who won a Nobel Peace Prize for his work raising awareness about climate change. “One of my fondest hopes is that people around the world will use Google Earth to see for themselves the reality of what’s happening because of the climate crisis.” Google Earth users now can plunge beneath the ocean’s surface, explore three-dimensional images of the underwater terrain, and view articles and videos about marine science contributed by scientists and organizations such as the National Geographic Society. The Historical Imagery feature lets users see archived satellite images of individual locations to see how the region has evolved over time as a result of climate change and other forces. For example, viewers can observe how the largest glacier in Glacier National Park has melted over the past decade. And with Google Mars 3D, users can view three-dimensional satellite imagery of the Red Planet taken during NASA space expeditions. Google Earth has been downloaded more than 500 million times since it was launched in 2005. The software is available for free on Google’s web site ( Researchers and organizations can purchase a more powerful version for $400.
