By Sean Buckley, Engadget, Aug 6, 2015 – Want to explore the surface of the red planet without signing up for the Mars One mission? No problem: NASA has built two interactive web applications that will let you explore the planet to your heart’s content from the comfort of your armchair.
Both of NASA’s new toys will give you a closer look at the surface of Mars, but from two very different vantage points. Mars Trek takes the Google Earth approach, laying over 50 years of NASA exploration data over an interactive 3D globe. It’s incredibly deep, including 3D and 2D views, video-game inspired controls and bookmarks showing off points of interest from previous NASA missions — in fact, it’s detailed enough that NASA is already using the program to scope out potential landing sites for its 2020 Mars rover.
