NASA is expanding its AI4Mars program with new images from the Perseverance rover exploring Mars. Once again, they’re looking to the public to help teach their robots.

After last year’s launch of AI4Mars, NASA developed the Soil Property and Object Classification (SPOC) with images from the Curiosity rover. All machine learning requires teaching, and with SPOC, anyone on earth could teach NASA’s AI to recognize geological features on Mars.

Originally, landscapes could be organized into four general categories, sand, soil, bedrock and big rock.

During the first stage of AI4Mars, members of the public helped to label nearly half a million images from the Curiosity rover. The program learned to properly identify sand, rock, and soil 98% of the time.

Now, the program includes more detailed labels, like islands of rock called float rocks or nodules of minerals. Using the Zooniverse program, designed to be simple enough for fourth graders to understand and use, anyone can draw polygons over images from Perseverance and label them as 6 new types of terrain.

The Perseverance rover is equipped with 19 cameras, and one of the most powerful self-driving systems to be sent into space, AutoNav. The Perseverance rover took its first AutoNav drive in July 2021, and is tasked with finding signs of ancient microbial life on Mars.

AutoNav works by developing 3D maps of the terrain ahead and responding to that as it moves. AutoNav works faster than any navigation system a rover has been equipped with before because of its ability to think and move at the same time. The Perseverance rover can move at a top speed of 393 feet per hour, while the Curiosity rover could only move at 66 feet per hour.

However, it has trouble distinguishing types of terrain that can be hazardous for rovers, like sandy areas, and scientists still need to identify areas that could be of interest.

Perseverance sends NASA anywhere from dozens to hundreds of images every day, and scientists only have hours to respond with instructions if they see something of interest.

SPOC is still in development, and would help to reduce the number of images coming back to earth, by giving the rover the capability to identify areas of interest on its own. Essentially, it’ll save NASA scientists time in planning routes for their rovers and in finding important formations.

“It would save us time if there was an algorithm that could say, ‘I think I saw rock veins or nodules over here,’ and then the science team can look at those areas with more detail,” said Vivian Sun, a JPL scientist who consulted on the AI4Mars project.

NASA needs help identifying features in about 20,000 images to make SPOC more sophisticated, in the hopes it can be used on a future expedition.

NASA launched the Perseverance rover in July of 2020 and it made its landing on Mars in February 2021. Perseverance is exploring the Jezero crater. In September 2021, the rover cored its first rock sample on Mars.
