NASA’s Perseverance rover is picking up its pace on Mars, thanks to technology that helps robots avoid problems with otherworldly units. The
technology, called AutoNav, is a navigation system that can map the terrain and plan routes, while the rover doesn’t need to rely too heavily on ground guidance. AutoNav is four to five times more powerful than the equivalent technology tested in NASA’s previous Mars rover, Curiosity, which means that Perseverance will be able to take more direct routes and travel faster, which in turn enables the rover to do more with the same amount. More scientific time.
“We will be able to get to where scientists want to go faster,” said Jennifer Trosper, Project Manager for the Mars Rover at NASA’s Jet Propulsion Laboratory (JPL) in California, in a NASA statement. “Now we can drive through these more complex terrains instead of avoiding them – this is not what we used to do.”

AutoNav process does not completely eliminate human drivers, it will only increase the range of the rover as much as possible.
JPL senior engineer, mobile vehicle planner and driver Vandi Verma said in the same statement: “We have a capability called’think while driving. The rover thinks about autonomous driving while the wheels are turning.”
Other features New Mars The car will also help increase speed. Percy’s wheels are larger in diameter, narrower in width, and have a more wavy tread pattern, designed by mission engineers to increase traction and durability on Mars. Perseverance is also equipped with a completely independent navigation computer. The new rover has a higher abdominal space and can safely explore more types of terrain.
“This is a rover driver’s paradise.”
Overall, the improvements implemented for Perseverance mean that the rover can reach speeds of 393 feet per hour compared to Curiosity’s speed of 66 feet (20 m) per hour. 120 meters) – slightly more than the length of a football field, which will allow Perseverance’s top speed to reach approximately 0.12 km / h (0.07 mph). Increasing the speed of the rover for Perseverance is important because mission scientists want to guide the rover to cover a total of 9 miles (15 kilometers) during its mission.
This is not only exciting for the scientists, but also for the humans who helped Perseverance navigate, as they can enjoy more views of the red planet in Jezero crater.
“Jezero is amazing,” said Verma. “This is a rover driver’s paradise. When you put on the 3D glasses, you will see that the terrain has more ups and downs. Sometimes I just look at the picture.”
