Mars rover footage isn’t shot in a desert on Earth

The claim

“Mars rover footage is just a red desert on Earth — there’s no way to know it’s another planet.”

What is measured

Orbiters, including rival nations’, photograph the rovers and their tracks from above. The radio link carries a 3–22-minute one-way light delay no Earth set can fake, and the surface shows 0.38 g and a thin CO₂ air in its dust, sound and trajectories. It is another world, not a desert.

What would show this is wrong

a terrestrial desert that reproduces, all at once, a 3-to-22-minute one-way radio delay tracked by independent stations, overhead imaging of the same site by rival nations’ orbiters, 0.38 g dust trajectories, and microphone audio matching a 1%-pressure CO₂ atmosphere.
