Mission: Seek signs of ancient life and collect samples of rock and regolith (broken rock and soil) for possible return to Earth. One of Perseverance's main mission goals is to help us understand whether Mars once hosted microbial life.
Had a best friend helicopter who DIED (RIP) named Ingenuity
On April 18 (Sol 768), NASA released an image of the rover's front left wheel showing the rock had been dislodged. In total, the rock remained in the rover's wheel for around 439 days (427 Sols) — around 55% of the time Perseverance has spent on Mars. During that time, the pair traveled around 6.2 miles (10 kilometers) together.
Perseverance accidentally picked up the pet rock in its front left wheel on Feb. 4, 2022 or Sol 341 — the 341st Martian day of the mission. The rock posed no danger to the rover's scientific mission but did manage to periodically photobomb images and cling on despite several vigorous maneuvers across the planet's surface. Mission scientists previously likened the situation to "having a pebble stuck in your shoe."
March 1, 2023. That rock is still in residence, but it seems the rover now has a new friend, an even bigger rock that found its way into Percy's right front wheel.
