Engineering models of the Curiosity Mars rover (foreground) and the Perseverance Mars rover share space in the garage at JPL’s Mars Yard. 

This stereo view from NASA's Curiosity Mars Rover shows the downwind side of a dune about 13 feet high within the Bagnold Dunes on Mars. The image appears three-dimensional when viewed through red-...

NASA Science missions circle Earth, the Sun, the Moon, Mars and many other destinations within our solar system, including spacecraft that look out even further into our universe. The Science Fleet...

This is an artist's concept of NASA's Curiosity rover tucked inside the Mars Science Laboratory spacecraft's backshell while the spacecraft is descending on a parachute toward Mars.

This left-eye member of a stereo pair of images from the Navigation Camera (Navcam) on NASA's Curiosity Mars rover shows a full 360-degree view of the rover's surroundings at the site where it firs...

Engineers put the rover through spin tests to ensure smooth sailing in space.

This sequence of seven images from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter shows wind-caused changes in the parachute of NASA's Mars Sci...

This artists concept of MSL is a still from the MSL Mission Overview video demonstrating the ChemCam instrument.

The artist's animation depicts how NASA's Curiosity rover will communicate with Earth during landing. As the rover descends to Mars, it will send out basic radio-frequency tones that go directly to...

Thick stacks of clay minerals indicate chemical alteration of thick stacks of rock by interaction with liquid water on ancient Mars.

This episode (part 4 of a 4 part series) shows Mars team members having a little fun on April 1, 2010 (April Fool's) at the end of an exhausting parachute test campaign. The team had just completed...
