<b>Russia planning double assault on Mars</b><br /><i>15:14 24 June 2005 <br />NewScientist.com news service <br />Kelly Young </i><br /><br />Russia is planning two uncrewed Mars missions, according to press reports. <br /><br />The first, in 2009, is a mission to orbit Mars and land on the tiny moon Phobos, where a rover would roam for three years. There, it would collect samples of soil to bring back to Earth – the first ever if successful. The second mission, scheduled for 2015, is to place a lander on the surface of the Red Planet.<br /><br />But Russia has had little success in its Martian missions. Since 1960, Russia, and the Soviet Union before it, has tried to send 17 probes to Mars - only three of those were unqualified successes. <br /><br />The Phobos 1 and 2 missions were dispatched to the Martian moon in 1988, but one failed on the way because of a software error. The other made it into orbit around Mars but a computer glitch prevented it from deploying a lander to Phobos’ surface. Russia’s most recent attempt to conquer the Red Planet was in 1996, when its Mars-96 orbiter did not even get out of Earth orbit.<br /><br />Russia has been working on a Phobos mission for several years, says a report by the UPI press agency. In theory, it should be easier to land on the Martian moons because a probe would only have to move alongside another orbiting object, rather than decelerate rapidly through the planet’s atmosphere. A sample return mission would also use less fuel escaping the tiny gravity of a moon compared to leaving the much larger planet.<br /><br /><b>Kicking up dust</b><br />A further advantage of landing on Phobos is that it is very close to Mars – just 9000 kilometres above the surface. From that vantage point, a spacecraft could also make detailed measurements of Mars. <br /><br />The proximity of Mars means Phobos is likely to have pieces of the planet on it. When large meteorites crash into Mars, they kick up rocks and soil.
