Mars 2020 Rover's 7-Foot-Long Robotic Arm Installed In this
image, taken on June 21, 2019, engineers at NASA's Jet Propulsion Laboratory in
Pasadena, California, install the main robotic arm on the Mars 2020 rover. (A
smaller arm to handle Mars samples will be installed inside the rover as well.)
The main arm includes five electrical motors and five joints (known as the
shoulder azimuth joint, shoulder elevation joint, elbow joint, wrist joint and
turret joint). 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, which is essentially its "hand."
"You have
to give a hand to our rover arm installation team," said Ryan van
Schilifgaarde, a support engineer at JPL for Mars 2020 assembly. "They
made an extremely intricate operation look easy. We're looking forward to more
of the same when the arm will receive its turret in the next few weeks."
The rover's turret
will include high-definition cameras, science instruments, and a percussive drill
and coring mechanism. Those tools will be used to analyze and collect samples
of Martian rock and soil, which will be cached on the surface for return to
Earth by a future mission.
Mars 2020 will launch from Cape Canaveral Air Force
Station in Florida in July of 2020. It will land at Jezero Crater on Feb. 18,
2021.
Charged with returning
astronauts to the Moon by 2024, NASA's Artemis lunar exploration plans
will establish a sustained human presence on and around the Moon by 2028. We
will use what we learn on the Moon to prepare to send astronauts to Mars.
JPL is building and will
manage operations of the Mars 2020 rover for the NASA Science Mission Directorate
at the agency's headquarters in Washington.
