Shaking Aspen Leaves Could Extend Life of Future Mars Rovers
You wouldn’t think leaves could be of any help in space????but the quivering leaves on Aspen trees may help save rovers on Mars????The leaves shake at even the smallest breeze thanks to their flat stems????A University of Warwick team wants to take from that unique movement????to create an energy-harvesting tool to power weather sensors in rough conditions ????They say it could also be used as a backup power supply to save Mars rovers????The loss of the Opportunity rover due to a massive dust storm proves it’d be useful????Dust covered the rover’s solar panels, so it wasn’t able to power back up????Their research was published in the journal Applied Physics Letters??
