Mars 2020 Rover Spun Up For Center Of Gravity Determination

Engineers took NASA’s Mars 2020 for a spin on Aug. 29, 2019. The two,300-pound (1,040-kilogram) Martian car was rotated clockwise and counterclockwise at about 1 revolution per minute on what is known as a spin desk within the clear room of the Spacecraft Meeting Facility at NASA’s Jet Propulsion Laboratory in Pasadena, California.

(The rotation was sped up within the video above.) The engineers had been in search of the rover’s heart of gravity, or the purpose at which weight is evenly dispersed on all sides.

Establishing the rover’s heart of gravity is a key a part of the meeting course of and helps be sure that the spacecraft travels easily from launch to entry, descent and touchdown on Mars as calculated. Engineers can add weights with a view to assist steadiness out the car. In the long run, they affixed 9 tungsten weights totaling 44 kilos (20 kilograms) to the rover chassis at predetermined attachment factors to get the middle of gravity good.

“The spin desk course of is just like how a gasoline station would steadiness a brand new tire earlier than placing it in your automobile,” stated Lemil Cordero, Mars 2020 mass properties engineer at JPL. “We rotate the rover forwards and backwards and search for asymmetries in its mass distribution. Then, just like your gasoline station placing small weights on the tire’s rim to carry it into steadiness, we’ll put small steadiness plenty on the rover in particular places to get its heart of gravity precisely the place we would like it.”

This was the assembled rover’s first spin desk take a look at to find out its heart of gravity; a second and remaining spin desk take a look at will happen at a NASA facility at Cape Canaveral in Florida subsequent spring.

JPL is constructing and can handle operations of the Mars 2020 rover for NASA. The rover will launch on a United Launch Alliance Atlas V rocket in July 2020 from House Launch Advanced 41 at Cape Canaveral. NASA’s Launch Companies Program, primarily based on the company’s Kennedy House Middle in Florida, is liable for launch administration.

When the rover lands at Jezero Crater on Feb. 18, 2021, it will likely be the primary spacecraft within the historical past of planetary exploration with the flexibility to precisely retarget its level of landing through the touchdown sequence.

Charged with returning astronauts to the Moon by 2024, NASA’s Artemis lunar exploration plans will set up a sustained human presence on and across the Moon by 2028. We’ll use what we be taught on the Moon to arrange to ship astronauts to Mars.
