NASA’s Perseverance Mars rover breaks 17-year-old driving record

By Trevor Mogg Published April 28, 2022

NASA’s Perseverance rover recently smashed the record for the longest drive on a single solar day on Mars, traveling 245.76 meters across the dusty surface.

The epic journey snatches the record set by Opportunity when it traveled just over 228 meters in March 2005 on a single solar day, which is about 40 minutes longer than a day on Earth.

NASA highlighted the record-breaking drive in a couple of tweets posted over the last couple of days:

There are no #WinterOlympics on Mars, but @NASAPersevere just broke two records! She achieved the longest drive in a single sol by a Martian rover (the previous record had been held by Opportunity for nearly 17 years) and surpassed her own record of longest AutoNav drive.🎉 https://t.co/pC4dEfX9ct

Perseverance, which landed on Mars in spectacular fashion a year ago this month, is exploring the Martian surface for signs of ancient life. It’s also collecting samples of rock for return to Earth by another mission, and gathering data that should prove useful for the first crewed mission to the red planet, though a solid date has yet to be set for that particular endeavor.

AutoNav

NASA’s most advanced Mars rover to date also beat its own record for the longest AutoNav drive. Perseverance is NASA’s first Mars rover to feature such a function, which enables the six-wheeled vehicle to safely traverse the Martian surface autonomously, with 3D maps and specially designed software helping it avoid obstacles such as large rocks and patches of loose sand.

The autonomous technology also allows Perseverance to move more rapidly than if it had humans planning the route. Manual routing can limit a Mars rover to 200 meters of travel in a day, while autonomous driving can see it move as far as 120 meters in just one hour.

For comparison, NASA’s other operational Mars rover, Curiosity, currently travels no faster than 20 meters per hour as it has no AutoNav function to automatically guide it.

NASA landed Perseverance in Jezero Crater, a dried lake bed that scientists believe offers the best chance of containing evidence of ancient life. The crater is about 28 miles (45 km) across, so there’s plenty of ground for Perseverance to cover as it explores its surroundings. Having that extra speed means the team can move Perseverance between sites of interest more quickly, enabling more research in a shorter space of time.

In recent days the rover overcame some issues with its sample collection mechanism, enabling it to continue its exploration of the distant planet.

Perseverance rover finds tantalizing hints of possible ancient life on Mars

mars 2020 perseverance rover

NASA's Perseverance rover was sent to Mars with one big, ambitious aim: to see if life could ever have thrived on our neighboring planet. Although there's unlikely to be anything alive on Mars now, the planet was once similar to Earth, with a thicker atmosphere and plentiful water on its surface. And during this time, billions of years ago, microbial life could have survived there. Now, Perseverance has located some tantalizing indications of possible microbial life -- although it's too early for scientists to be sure.

The rover has been taking samples by drilling into the martian rock as it travels, and it's a recent sample from an area called the Cheyava Falls that has ignited interest. The rock, collected on July 21, has indications of chemical signatures and physical structures that could potentially have been formed by life, such as the presence of organic compounds. These carbon-based molecules are the building blocks of life; however, they can also be formed by other processes.

How NASA is using AI on the Perseverance rover to study Mars rocks

akdjf alkjdhf lk

Space engineers have been using AI in rovers for some time now -- hence why today's Mars explorers are able to pick a safe landing site and to drive around a region autonomously. But something they haven't been able to do before now is to do science themselves, as most of that work is done by scientists on Earth who analyze data and point the rover toward targets they want to investigate.

Now, though, NASA's Perseverance rover is taking the first steps toward autonomous science investigation on Mars. The rover has been testing out an AI capability for the last three years, which allows it to search for and identify particular minerals in Mars rocks. The system works using the rover's PIXL instrument (Planetary Instrument for X-ray Lithochemistry), a spectrometer that uses light to analyze what rocks are made of. The software, called adaptive sampling, looks though PIXL's data and identifies minerals to be studied in more detail.

NASA axes its moon rover project VIPER

NASA’s VIPER – short for the Volatiles Investigating Polar Exploration Rover – sits assembled inside the cleanroom at the agency’s Johnson Space Center.

NASA has announced it is scrapping its plans to send a rover to the moon. The Volatiles Investigating Polar Exploration Rover, or VIPER, project was intended to search the moon's polar regions for water, but will now be shelved due to budget issues. Originally slated to land on the moon in December 2022, the project had been delayed several times, and the most recent update was that it would not be ready until September 2025.
