The engineers took NASA
March 2020 for a tour on August 29, 2019. The 2300 books
(1,040 kilograms) the Martian vehicle was shot
clockwise and counterclockwise at about 1 round per minute on that which is
called a spin table in the clean room of the spacecraft assembly facility at NASA
Jet propulsion laboratory in Pasadena, California. (The
the rotation was accelerated in the video above.) The engineers were looking for the
center of gravity of the rover, or the point at which
the weight is evenly dispersed on all sides.
Establish the
center of gravity of the rover
a key part of the assembly process and helps ensure that the spacecraft travels
smooth launch launch, descent and Mars-calculated landing. engineers
can add weight to help balance the vehicle. In the end, they
affixed nine tungsten weights totaling 44 pounds (20 kg) on the mobile
chassis to predetermined attachment points to get the right center of gravity
right.
"The spin
table process is similar to how a service station would balance a new tire before putting
on your car, "said Lemil Cordero, an engineer in mass properties for March 2020 to
JPL. "We rotate the rover and look for asymmetries in its mass distribution.
Then, similar to your gas station putting small weights on the rim of the tire to bring
in balance, let's put small balancing weights on the rover in particular
places to get its center of gravity exactly where we want it. "
It was the
first turntable test of the assembled rover to determine its center of gravity; a
second and final test of table rotation in a NASA facility at Cape
Canaveral Florida next spring.
JPL builds and will manage the operations of March 2020
mobile for NASA. The rover will be launched on a United Launch Alliance Atlas V
rocket in July 2020 from the space launch complex 41 at Cape Canaveral. NASA's Launch Services Program, based at
Kennedy Space Center of the agency in Florida, is responsible for the management of launches.
When the rover lands at the crater of Jezero on February 18, 2021, it will be
to be the first spaceship in the history of planetary exploration with the
ability to accurately re-target the landing point during the landing
sequence.
Accused to return
Astronauts on 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.
