Access Mars is a WebVR experience developed in collaboration with Google, adapted from JPL's OnSight software. Imagery from NASA's Curiosity rover provided the terrain, allowing users to wander the actual dunes and valleys explored by the spacecraft. Access Mars lets anyone with an internet connection take a guided tour of what those scientists experience. A simple walkthrough explains what the Curiosity rover does and details its dramatic landing in 2012. Users also can visit four sites that have been critical to NASA's Mars Science Laboratory mission: Curiosity's landing site; Murray Buttes; Marias Pass and Pahrump Hills. Additionally, the rover's latest location on lower Mt. Sharp will be periodically updated to reflect the mission's ongoing progress. To date, Access Mars has had more than 15,000 hours of use, from users in all parts of the world.
