The Cerberus Fossae are a group of troughs in the Cerberus region of Mars that run roughly parallel to one another. They formed due to extension of the crust in the region. Some of the troughs, suc...

This illustration shows a concept of what a rover fetching rock and soil samples on Mars for return to Earth could look like.

An artist's rendering of Mars Pathfinder, which consisted of a lander and the first-ever robotic rover on the surface of the Red Planet. 

​As part of a Mars sample return mission, a rocket will carry a container of sample tubes with Martian rock and soil samples into orbit around Mars and release it for pick up by another spacecraft. 

Meet two of the Martian samples that have been collected and are awaiting return to Earth as part of the Mars Sample Return campaign. As of late June 2023, NASA’s Mars Perseverance rover has collec...

On June 21, 2019, engineers at NASA's Jet Propulsion Laboratory install the main robotic arm on the Mars 2020 rover.

This graphic shows how the energy available to NASA’s Opportunity rover on Mars (in watt-hours) depends on how clear or opaque the atmosphere is (measured in a value called tau). When the tau value...
