The bit carousel, which lies at the heart of the rover's Sample Caching System, is now aboard NASA's newest rover.

The first briefcase-size CubeSats to journey to another planet have been honored for their role in NASA InSight's successful Mars landing.

NASA's Curiosity rover is discovering odd rocks halfway into a region called the "clay-bearing unit."

Lost in the publicity glare following the Apollo 11 Moon landing, two intrepid robotic spacecraft flew by Mars in the summer of 1969.

In this time-lapse video, the robotic arm on NASA's Mars 2020 rover maneuvers its 88-pound (40-kilogram) sensor-laden turret as it moves from a deployed to stowed configuration.

NASA gives the go-ahead to fuel the Mars 2020 rover's Multi-Mission Radioisotope Thermoelectric Generator, which will power rover and help keep it warm while exploring Mars.

Quakes look and feel different depending on the material their seismic waves pass through. In a new video, scientists demonstrate this by using quake data from Mars, Earth and the Moon.

The launch period for NASA's next rover, Mars 2020, opens exactly one year from today, July 17, 2020, and extends through Aug. 5, 2020.

A dramatic Martian landscape can be seen in a new image taken from space, showing NASA's Curiosity rover.

Constructing an exquisitely complex vehicle like the Mars 2020 rover takes serious teamwork.

Robots can drive on the plains and craters of Mars, but what if we could explore cliffs, polar caps and other hard-to-reach places on the Red Planet and beyond?

"What we needed was a Neil Armstrong for Mars. What we came up with was Terrain-Relative Navigation."

Last week, the spacecraft's robotic arm successfully removed the support structure of the mole, which has been unable to dig, and placed it to the side.

NASA has selected eight new research teams to collaborate on research into the intersection of space science and human space exploration as part of the Solar System Exploration Research Virtual Institute (SSERVI).

The Mars 2020 ‘Name the Rover’ contest will be open to students in the fall of 2019.

NASA's Curiosity Mars rover found a surprising result: the largest amount of methane ever measured during the mission.

NASA has selected three finalists among a dozen concepts for future small satellites.

Engineers at JPL take a group selfie after attaching the remote sensing mast to the Mars 2020 rover.

The forecast for the next solar cycle says it will be the weakest of the last 200 years.

The next robotic Mars mission will carry technology that will help enable astronauts to eventually explore the Red Planet.

NASA's Mars Helicopter flight demonstration project has passed a number of key tests with flying colors.

Scientists and engineers have a new plan for getting NASA InSight's heat probe, also known as the "mole," digging again on Mars.

NASA's Curiosity rover has confirmed that the region on Mars it's exploring, called the "clay-bearing unit," is well deserving of its name.

On a test flight in Death Valley, California, an Airbus helicopter carried an engineering model of the Lander Vision System (LVS) that will help guide NASA's next Mars mission to a safe touchdown on the Red Planet.
