Cameras from the Mars rover Perseverance have allowed scientists to make an interesting discovery. An unusual piece of debris has been noticed in the footage - a fragment of thermal protection that was wrapped around the rover during its descent to the Martian surface. Scientists have suggested that it may have detached during descent or been blown off the surface by Martian winds. The rover landed in 2021 and the thermal protection fragment has had enough time to travel to a new location.
