The Mars 2020 rover is preparing for its big mission by doing some “bicep curls” in a new video released by NASA.
The rover will head to Mars in July 2020 and is scheduled to land on the Red Planet’s Jezero Crater in February 2021.
It’s a big mission to prepare for: the rover will collect samples from rock and soil on the planet’s surface.
Both will be heavy, so NASA has decided to give its arms a good workout.
The robotic arm is seven feet long and weighs 88 pounds.
There’s five electric motors and five joints that mimic the movement of an actual human arm.
