Curiosity Mars rover takes a new selfie before record climb

NASA's Curiosity Mars rover recently set a record for the steepest terrain it's ever climbed, cresting the "Greenheugh Pediment," a broad sheet of rock that sits atop a hill. And before doing that, the rover took a selfie, ...

NASA's Mars 2020 rover goes coast-to-coast to prep for launch

NASA's next Mars rover has arrived in Florida to begin final preparations for its launch to the Red Planet this July. Two Air Force C-17 Globemaster cargo planes carrying the Mars 2020 rover as well as the cruise stage, descent ...

Mars 2020 rover to seek ancient life, prepare human missions

The Mars 2020 rover, which sets off for the Red Planet next year, will not only search for traces of ancient life, but pave the way for future human missions, NASA scientists said Friday as they unveiled the vehicle.

Image: A cloudy martian night through the eyes of a supercomputer

As NASA's Curiosity rover makes its way over the surface of Mars, it's sometimes accompanied by clouds drifting by in the sky above. Like Earth, the Red Planet has a water cycle, with water molecules moving between the surface ...

ESA's Mars orbiters did not see latest Curiosity methane burst

In June, NASA's Curiosity rover reported the highest burst of methane recorded yet, but neither ESA's Mars Express nor the ExoMars Trace Gas Orbiter recorded any signs of the illusive gas, despite flying over the same location ...

Astronauts to test drive a lunar robot from the space station

Astronauts could one day remotely control Moon and Mars rovers from orbit. An upcoming test aboard the International Space Station could help make this a possibility. In November, the ESA (European Space Agency) will conduct ...

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.)
