One summer night in 1877, American astronomer Asaph Hall was looking through his telescope in Washington, D.C. Mars was at ...

Mars has two small moons that may have formed in the aftermath of a giant impact. Simulations suggest that Phobos and Deimos accreted from the disperse outer region of the debris disc that was ...

Billions of years ago, Mars suffered from numerous big impacts, and the resulting backwash ultimately scarred the surface of Phobos, one of the Red Planet's two tiny moons, researchers say. In the ...

The origin of Phobos and Deimos, the two Martian moons, has been a mystery to astronomers. These two bodies are a fraction of the size and mass of the Moon, measuring just 22.7 km (14 mi) and 12.6 ...

Phobos is such a close companion of Mars, about 60 times closer than the moon orbiting Earth, that it has crossed with MAVEN’s path multiple times a day during the orbiter’s mission.

Phobos is one of the two moons that revolve around Mars. It's a lumpy, crater-filled pile of rubble that measures only 10 by 14 by 11 miles (17 by 22 by 18 km).

The martian moons Phobos and Deimos are the only two natural satellites in the inner Solar System apart from Earth's own Moon. They are much smaller than Earth's natural satellite and, due to the low ...

But Phobos has such low gravity that traveling too fast could send you spinning off the moon and into space. A rover for such an environment needs to be able to grip onto the ground in order to ...

JAXA, CNES and DLR sign a cooperation agreement on the MMX mission on 20 June 2023 in Paris. The Institute of Robotics and Mechatronics is coordinating the project on the DLR side. "We are delighted ...
