Robots have finally risen to meet NASA's moon dirt digging competition after three years of failure. Three robotics teams took away a total of $750,000 in prize money by proving they could dig at least 330 pounds of simulated lunar regolith within half an hour.
The first place robot alone excavated 1,103 pounds of dirt and deposited it in a container within the time limit. Competitors not only had to dig out the sticky regolith grains, but also had to be light enough to meet a weight restriction of no more than 176 pounds.
British scientists try to engineer soils that suck carbon out of the air

Getting carbon dioxide out of the atmosphere is just one step. After plants and trees pull CO2 out of the air, some of the surplus carbon is funneled down into the soil, where it can then re-enter the atmosphere or seep into groundwater. To trap this excess carbon, Newcastle University scientists are trying to design new kinds of soils that would transform the stuff into calcium carbonate, keeping it down in the ground.
