NASA's robotic rover Curiosity is making its mark on Mars - leaving tracks that are big enough to be seen from space.
Curiosity's zig zagging tyre tracks were photographed by a NASA satellite circling the red planet and also from the rover's rear-facing cameras.
Observing the tracks over time will provide information on how the surface of Mars changes as dust is deposited and eroded.
The spacecraft landed on 5 August on a mission to look for ingredients that could support life.
The rover won't be moving around for several days as engineers are to spend the next week inspecting the rover's crucial robotic arm and scientific instruments.
