Mars Pathfinder & Sojourner Rover (360 View) Explained

Thanks to new technology, we can take a 360-degree tour of the 1997 Pathfinder mission landing site, including Sojourner, the first Mars rover. Check out this interactive YouTube panorama, and then…

…keep scrolling to find out more about each point of interest, how the Pathfinder mission compares to “The Martian” and NASA’s real Journey to Mars.



“Yogi” is a meter-size rock about 5 meters northwest of the Mars Pathfinder lander and the second rock visited by the Sojourner Rover’s alpha proton X-ray spectrometer (APXS) instrument. This mosaic shows super resolution techniques applied to help to address questions about the texture of this rock and what it might tell us about how it came to be.


Twin Peaks

The Twin Peaks are modest-size hills to the southwest of the Mars Pathfinder landing site. They were discovered on the first panoramas taken by the IMP camera on the July 4, 1997, and subsequently identified in Viking Orbiter images taken over 20 years ago. They’re about 30-35 meters tall.


Barnacle Bill

“Barnacle Bill” is a small rock immediately west-northwest of the Mars Pathfinder lander and was the first rock visited by the Sojourner Rover’s alpha proton X-ray spectrometer (APXS) instrument. If you have some old-school red-cyan glasses, put them on and see this pic in eye-popping 3-D.


Rock Garden

The Rock Garden is a cluster of large, angular rocks tilted in a downstream direction from ancient floods on Mars. The rocky surface is comprised of materials washed down from the highlands and deposited in this ancient outflow channel.
