Mars rover is yet to find 'perfect' rock sample almost two months into its search for past life

NASA's Perseverance rover has been aptly named because -- nearly two months after beginning its search into past life on Mars -- it has still yet to find any viable samples. The car-sized robot began its mission to find ancient biomarkers in the Martian clay on April 22, which could indicate if alien life ever existed on the Red Planet. It has been roaming around an ancient delta to look for sampling sites that might contain ancient microbes and organics. The rover then drills down to extract a specimen that it plans to leave at the base of the delta to be retrieved in future missions. However, NASA has since revealed that, so far, no samples have been successfully collected. The fragile clay materials the rover targets have been known to fracture, crack and crumble during the abrasion and coring process.
