At Arm's Length

On June 21, 2019, engineers at NASA's Jet Propulsion Laboratory install the main robotic arm on the Mars 2020 rover.

June 28, 2019

On June 21, 2019, engineers at NASA's Jet Propulsion Laboratory install the main robotic arm on the Mars 2020 rover. Measuring 7 feet (2.1 meters) long, the arm will allow the rover to work as a human geologist would: by holding and using science tools with its turret.
