    Something simple, like a bolt from one of the rovers. But make sure it’s from one that has never been in that half of the planet.

      A standard automotive bolt. Maybe something that was ubiquitous in the 1950’s but isn’t used today in place of something cheaper and more reliable

      I was thinking a slab of granite with “ELON MUSK; 28-JUN-1971 - 31-MAR-2022” carved into it.

    Not a single act, but a series of actions. The rovers power down during Martian nights, right? So, during these periods, you could rearrange the rocks nearby. At first, NASA might not even pick up on the changes, but eventually, someone’s bound to notice.

    Imagine the buzz it would create! The scientists studying the photographs sent back by the rovers would be left scratching their heads. They’d probably first suspect some unknown natural phenomena, or even the rovers themselves, until the changes became too orchestrated to explain away. It would be a cosmic puzzle, a Martian mystery that would have them combing through data for answers.

    No extraordinary or unnatural objects, just ordinary Martian rocks moved around. Instead of presenting them with an object that screams ‘alien intervention,’ you’d be nudging them into a mystery, all with the Martian surface’s naturally occurring elements.

      The rocks change in a pattern, I swear it’s a single character substitution cipher! Wait a minute… “drink more Ovaltine” what the crap?

      That would definitely fuck with NASA, i can already see Youtube Videos being made about this and their being theories and stuff. This would also be very interesting, how would the Governments react to this? How will UFO Conspiracy Theorists respond to this?

        Continue to escalate the situation until it reaches a fever pitch, then stop cold for a week

    A half-eaten tuna sandwich. By the time they manage to retrieve it for examination, it would definitely be all soggy.

    My body in a lawn chair, with my right thumb extended out for hitchhiking, my left hand holding an American flag, and a sign in my lap saying “California or bust!”

    An altered skeleton, half buried. Give it a larger than normal skull or extra long arms or toes or something like that.
