Phobos, the larger of the two moons of Mars has many unknowns. For instance, what formed the grooves that run across its surface? Image: ESA/DLR/FU Berlin (G. Neukum)From Discover:
The Fobos-Grunt mission might pave the way for humanity's first permanent space base—on Phobos, Mars' bizarre moon.
Mars has been nothing but bad luck for the Russians. They have launched 20 probes to the planet since 1960, and all either failed or suffered from severe technical problems. But soon—as early as this October—Russia will attempt to reverse its fortunes with one of the most ambitious unmanned space missions ever.
Instead of aiming straight for Mars, the Russians are going after Phobos, the larger of its two little satellites and one of the oddest objects around. Their probe, called Fobos-Grunt (“Phobos soil” in Russian), will not only land on Phobos but also scoop up some samples of the surface and send them to Earth. Understanding Phobos could tell us a lot about the early history of the solar system. “It may give us clues to the formation of Earth’s moon and the moons of the other planets, and the role played by asteroid impacts in shaping the terrestrial [rocky] planets,” says Alexander Zakharov of the Moscow-based Space Research Institute and chief scientist for Fobos-Grunt. Even more important, this mission could lay the groundwork for an innovative strategy for exploring—and even colonizing—Mars itself.
