A new study challenges the long-standing assumptions about the origin of Mars’s moons by suggesting the Red Planet may have ...

The spacecraft, however, was marooned in Earth orbit due to issues with its rocket. Phobos-Grunt fell back to Earth in early 2012 and crashed into the Pacific Ocean. NASA may not be finished with ...

But each time these eclipses are observed, scientists say they can measure subtle shifts in Phobos’ orbit as that fatal day approaches. While Spirit and Opportunity made the first observations ...

On 26 January, Mars Express completed its 7777th orbit around the Red Planet, an auspicious milestone as the satellite is readied for the closest-ever flyby of Phobos, scheduled for just a few ...

Most likely a 4 billion year-old asteroid, captured in an equatorial Mars orbit of less than 6,000 kms, Phobos circles the Martian landscape every 7 hours and 39 minutes. By comparison ...

"Each time these eclipses are observed, they allow scientists to measure subtle shifts in Phobos’ orbit over time," NASA explained after a previous eclipse in 2022. "The moon’s tidal forces ...

Phobos-Grunt probe, meant to land on Martian moon, instead stuck in Earth orbit. Nov. 9, 2011 — -- A Russian space probe called Phobos-Grunt-- launched on an ambitious mission to return soil ...

Europe's Mars Express spacecraft has peered deeper into the subsurface of the Martian moon Phobos than ever before, finding hints of unknown structures that could be clues as to the moon's origin.

Russia’s troubled Phobos-Grunt spacecraft, which is stuck in low-Earth orbit due to an engine failure rather than on its way to Mars, appears to be doomed, with small pieces of the wayward probe ...

Russia and the former Soviet Union haven't had much luck when it comes to missions to the red planet. On Tuesday, it launched a probe destined for Mars. It was supposed to land on Phobos, one of ...

Mars' two moons, Phobos and Deimos, are small, irregular, but orbit in the same equatorial plane as the red planet. Although they've long been thought to be captured asteroids, those orbits would ...

(PhysOrg.com) -- On 26 January, Mars Express completed its 7777th orbit around the Red Planet, an auspicious milestone as the satellite is readied for the closest-ever flyby of Phobos, scheduled ...
