Before packaging it up and blasting it to the Red Planet, engineers at JPL gave the helicopter a trial run in a special wind tunnel designed with help from researchers at Caltech. To simulate flying on a planet where the atmosphere is 100 times thinner than Earth’s, a custom wind tunnel was built inside of an 85-foot-tall, 25-f...
