The first self-driving vehicle on Mars has proven to be a smashing success
Sometime next week, NASA's newest rover on Mars, Perseverance, will set a record for the most distance driven by any vehicle on another world. The automobile-sized rover, which landed on Mars in February 2021, will traverse beyond 45.16 km (28.06 miles) across the Martian surface. In doing so it will break the previous distance record held by the long-lived Opportunity rover, which ceased communications with NASA in 2018. So how did Perseverance reach this record-setting distance in just a third of the time? Read full article Comments
Sometime next week, NASA's newest rover on Mars, Perseverance, will set a record for the most distance driven by any vehicle on another world.
The automobile-sized rover, which landed on Mars in February 2021, will traverse beyond 45.16 km (28.06 miles) across the Martian surface. In doing so it will break the previous distance record held by the long-lived Opportunity rover, which ceased communications with NASA in 2018.
About 90 percent of the distance driven by Perseverance has been autonomous.
“The real enabling technology has been its auto navigation system,” said Steven Lee, the project manager for the Perseverance rover at NASA’s Jet Propulsion Laboratory, in an interview.
Much like self-driving cars on Earth, Perseverance has sophisticated onboard cameras that image the surrounding terrain, and these images are then processed algorithmically by an onboard computer to calculate the safest route. Terrestrial vehicles have some advantages of course, like clearly defined maps, street signs, lanes, and more. Additionally there are plenty of “road” hazards on Mars, from large boulders to sandy slopes. But at least Perseverance does not have to contend with other traffic and bad drivers.
