Puzzling finds range from rocks that look like turtles or sharks to a lightsaber.
But while the Star Wars weapon is actually a titanium tube dropped by the rover and containing a rock sample, other sights have left space fans guessing what they could be.
Notable sightings have seen Mars rocks that resemble a giant egg, a Harry Potter sorting hat shape and a Martian sombrero.
In March 2025, the Perseverance Science Team said they were "astonished by a strange rock" comprised of hundreds of millimetre-sized spheres – some with tiny pinholes.
In 2022, a Martian stone that had been hitching a ride on Perseverance's wheel finally fell off. NASA staff had dubbed it an "unexpected travelling companion".
While in 2024, it made a significant find: the "Cheyava Falls" rock that provides possible evidence of ancient life on Mars.
NASA's History Office posted on X: "Celebrating 5 years on Mars! NASA's Perseverance Rover safely landed on the surface of the Red Planet 5 years ago, ready to begin its search for signs of past life.
"In 2024, it made a significant find: the "Cheyava Falls" rock pictured here provides possible evidence of ancient life on Mars!"
