ESA is showing off its new "ExoMars" bots, Bruno and Bradley, who are being prepped for a 2015 mission to the red planet. The six-wheeled bots are being designed to carry a significant scientific payload, oriented around the search for life, but won't slouch in the maneuverability department, with six independently rotating wheels. In addition to independent movement, the wheels can also be locked into "wheel walking mode," where treacherous terrain can be traversed by crawling instead of rolling over it. On the AI front, Bruno and Bradley have significantly better AI than their progenitors, being able to plot their own courses and therefore cover more ground. The mission will involve traversing the planet and drilling six feet into the ground for soil samples, which the rover will be able to examine in its on-board laboratory. The only problem now is funding: ExoMars is looking to cost about double the 650 million Euros initially approved for the project in 2005, and there's no guarantee (yet) that the extra cash will be there when they need it.

Even though we were pretty sure that the whole "life on Mars" issue had already been settled, scientists are still hell-bent on sending robots to scope out the Red Planet to look for tiny Martians, with the British unveiling a new rover today that promises to school hometown favorites Spirit and Opportunity at that very task. "Bridget," as the six-wheeled bot is known, can supposedly cover in just six months the same 6.2-mile stretch that's taken the American rovers over two years, thanks to a guidance system that allows for greater autonomy and requires less terrestrial control. Designed to compete for a spot on the European Space Agency's planned 2011 ExoMars mission, Bridget sports a two-meter drill, a so-called "life marker chip," and a micro seismometer, among other toots, to help enable the Agency's long-term goal of safely sending humans to our neighbor planet. And because half the battle is just getting there, engineers equipped the new bot with sensors that will let on-board airbags and parachutes guide it to a safer, more controlled landing -- ensuring that Bridget doesn't go MIA like the Beagle 2 rover in 2003, .
