Things can get lonely on Mars. NASA’s four-wheeled robot has been roaming the Red Planet for more than three years, trekking across the harsh terrain on its own after losing its pal Ingenuity. But perhaps the Martian rover has found a way to connect with us from 140 million miles away.
On July 4, 1997, a tiny, flat robot touched down on the surface of Mars and became the first wheeled vehicle to roam around on another planet. Since then, a fleet of Martian rovers have followed in the tracks of Sojourner and they have become bigger, better, and more autonomous over the years.
NASA’s Perseverance rover, equipped with an advanced computer pilot known as AutoNav, has been making significant strides on the Martian surface, setting new speed records since its landing in February 2021.
