The Perseverance Mars rover took a selfie with several of the 10 sample tubes it deposited on the Martian surface.
One of the main jobs for the Perseverance Mars rover past few weeks has been collecting carefully selected samples of Mars rock and soil.
These samples have been placed and sealed in special sample tubes and left in well-identified places so that a future sample return mission can collect them and bring the Martian samples back to Earth.
