Feel the Burn! Watch NASA's 2020 Mars Rover Do a Bicep Curl (Video)

In a minidisplay of robot Olympian power, NASA's next Mars rover easily bicep-curled 88 lbs. (40 kilograms) in a California clean room.

A new video shows the Mars 2020 rover flexing its joints as huddling technicians at NASA's Jet Propulsion Laboratory (JPL) supervise the spacecraft's every move. The rover was moving around a hefty turret that includes HD cameras, a percussive drill, a coring mechanism and other instruments to examine the composition of Mars rocks.

"This was our first opportunity to watch the arm and turret move in concert with each other, making sure that everything worked as advertised — nothing blocking or otherwise hindering smooth operation of the system," said Dave Levine, integration engineer for Mars 2020, in a JPL statement.

"Standing there, watching the arm and turret go through their motions, you can't help but marvel that the rover will be in space in less than a year from now and performing these exact movements on Mars in less than two," Levine added.

(40 kilograms) sensor-laden turret as it moves from a deployed to a stowed configuration.  (Image credit: NASA/JPL-Caltech)

The rover is scheduled to launch from Cape Canaveral Air Force Station in Florida in July 2020 and land inside Mars' Jezero Crater on Feb. 18, 2021. 

Once there, Mars 2020 will characterize the geology of the area, which hosted a river delta in the ancient past, and search for signs of long-dead life. 

The six-wheeled robot will also cache the most-promising samples, for possible return to Earth in the coming years. Mars 2020 has a suite of powerful instruments, but labs here on Earth have much more capable and diverse science gear, the kind of advanced equipment that might be necessary to spot a Martian biosignature in ancient rocks.

Mars 2020's observations will also help NASA prepare for human exploration on the Red Planet in future decades, agency officials have said. NASA is working to land humans on the moon by 2024, to help prepare for crewed missions to Mars in the 2030s.
