Abandoned Property

Everything they left behind.

Roughly seven metric tons of hardware now sits on the property, per a widely cited 2022 estimate. None of it was cleared with the owner. Almost none of it is coming back.

Unclaimed Property Notice

Under Property Rule 8, owners of items left on the property have 30 sols from the date of this notice to arrange collection. After that, items are classified as abandoned and become the property of the Owner. The Owner would prefer they be collected.

Backshell and parachute Perseverance Jezero Crater Photographed from the air by Ingenuity in April 2022. The trespassers flew over to take pictures of their own litter.
Descent stage (sky crane) Perseverance Jezero Crater Lowered the rover, then flew away and crashed into the property on purpose. Standard procedure, per the operator.
Descent stage (sky crane) Curiosity Gale Crater Same procedure, 2012. Intentional crash on the property. First offense.
Sample tubes (10) Perseverance Three Forks depot, Jezero Crater Deposited between December 2022 and January 2023, awaiting a pickup that has not been scheduled. The property is not a package locker.
Helicopter and rotor blade fragment Ingenuity Valinor Hills, Jezero Crater Grounded after its 72nd flight in January 2024. A piece of blade was photographed some distance from the aircraft.
Heat shield Opportunity Meridiani Planum The rover later drove back to inspect its own discarded heat shield, found a meteorite beside it, and studied that too. Neither was returned.
Lander, airbags, and ramps Mars Pathfinder Ares Vallis Left fully assembled, with a small rover parked beside it.
Debris field (parachute, backshell, heat shield, impact crater) Schiaparelli Meridiani Planum All components visible from orbit. The crater is new. The property did not have a crater there before.
Partially deployed lander Beagle 2 Isidis Planitia Missing for 11 years. Located in 2015. Not collected.
Heat probe ("the mole") InSight Elysium Planitia Designed to dig five meters down. Stayed near the surface after two years of hammering. Now buried in the property permanently.
Two landers Viking 1 and Viking 2 Chryse Planitia and Utopia Planitia Intact. Abandoned in 1982 and 1980. Now the oldest abandoned vehicles on the property.
Lander with broken solar panels Phoenix Vastitas Borealis Panels broken under the weight of seasonal ice. Left where it stood.
Rover, stuck Spirit Gusev Crater (Troy) Still stuck. The owners stopped trying in 2011.
Wreckage, location unconfirmed Mars 2, Mars 6, Mars Polar Lander, Deep Space 2 Various Somewhere on the property. Nobody knows exactly where. That is not reassuring.
Wheel tracks Multiple Property-wide Over 45 km from Opportunity alone. Tread marks are visible from orbit.
AA note on the sample tubes

The property is not a package locker.

Between December 2022 and January 2023, Perseverance set ten sealed tubes down on the floor of Jezero Crater at a site its operators call Three Forks. The tubes contain rock and soil cored out of the property. They were placed there so that a future mission could come and take them off the property.

To be clear about what happened: someone drilled into the owner's land, packed up what they found, and left it by the door for a courier. No courier has been confirmed.

The Office has addressed this in Notice NOT-2026-002.
