Photos show lost Mars lander

New supersharp photos of Mars show Europe's long-lost Beagle 2 lander, ancient Red Planet lake beds and snaking rover tracks in unprecedented detail. Scientists "stacked and matched" photos captured over the years by NASA's eagle-eyed Mars Reconnaissance Orbiter (MRO) using new machine-vision methods, creating images in which features just 2 inches wide can be seen. This resolution is five times greater than MRO or any other instrument orbiting Earth or Mars had been able to achieve, researchers said. Further use of this technique could help space agencies select safe landing sites for future Mars missions, search for pieces of other lost Red Planet hardware and perform a variety of other science work, they added. "We now have the equivalent of drone-eye vision anywhere on the surface of Mars where there are enough clear repeat pictures," study co-author Jan-Peter Muller, of University College London's Mullard Space Science Laboratory, said in a statement.
