Perseverance Rover will peer beneath Mars' surface

After touching down on the Red Planet Feb. 18, 2021, NASA's Mars 2020 Perseverance rover will scour Jezero Crater to help us understand its geologic history and search for signs of past microbial life. But the six-wheeled ...

New Mars rover is ready for space lasers

When the Apollo astronauts landed on the Moon, they brought devices with them called retroreflectors, which are essentially small arrays of mirrors. The plan was for scientists on Earth to aim lasers at them and calculate ...

'On our way to Mars': NASA rover will look for signs of life

The biggest, most sophisticated Mars rover ever built—a car-size vehicle bristling with cameras, microphones, drills and lasers—blasted off for the red planet Thursday as part of an ambitious, long-range project to bring ...

Mars 2020 mission to be guided by USGS astrogeology maps

When NASA's Perseverance rover lands on Mars next year, it will be equipped with some of the most precise maps of Mars ever created, courtesy of the USGS Astrogeology Science Center. Not only are the new maps essential for ...

As Mars exploration prepares for a rebirth, a European rover tunes up its gear for the challenges ahead.

Curiosity Mars rover's summer road trip has begun

NASA's Curiosity Mars rover has started a road trip that will continue through the summer across roughly a mile (1.6 kilometers) of terrain. By trip's end, the rover will be able to ascend to the next section of the 3-mile-tall ...

How life on Earth could help us find life on Mars

In our continuing search for other life in the universe, one place has always looked promising—Mars. It is a rocky planet like Earth, orbiting the same star, and at a distance where water could have been present on the ...

Mars rover

A Mars rover is a spacecraft which propels itself across the surface of Mars after landing.

Rovers have several advantages over stationary landers: they examine more territory, they can be directed to interesting features, they can place themselves in sunny positions to weather winter months and they can advance the knowledge of how to perform very remote robotic vehicle control.

Their advantages over orbiting spacecraft are that they can make observations to a microscopic level and can conduct physical experimentation. Disadvantages of rovers compared to orbiters are the higher chance of failure, due to landing and other risks, and that they are limited to a small area around a landing site which itself is only approximately anticipated.

There have been three successful Mars rovers, all of which were robotically operated. (There have also been two successful non-Martian robotic rovers: in the 1970s the USSR sent two Lunokhod rovers to the Moon.)
