Perseverance
The rover you're driving — a nuclear-powered robot geologist.
Landed in Jezero Crater on 18 February 2021; seals rock cores in titanium sample tubes for a future return to Earth.

The Mars Yard
You built the rover. Now drive it — across butterscotch hills, past the machines that came before it.
This is Jezero as a proving ground: NASA's own Perseverance model under your keys, Curiosity parked on the rise, Ingenuity flying its slow figure-eight overhead, and ten titanium sample tubes waiting at the depot. Reach every marked site to earn the Mars Yard Explorer badge.

The fleet in the yard
Curiosity
The elder rover, parked in the yard.
Landed in Gale Crater in August 2012 and is still driving — the longest-serving active rover on Mars.
Ingenuity
The helicopter flying its figure-eight overhead.
Flew 72 flights between 2021 and 2024 — the first powered, controlled aircraft on another world.
Three Forks depot
Ten titanium sample tubes, cached on the surface.
Dropped by Perseverance across six weeks in late 2022 and early 2023 — the first sample depot on another planet.

Now the real planet.
You've driven the yard — now explore the Mars the fleet actually works on, mission by mission.
Build the machine you just drove.
Assemble Perseverance system by system in the rover bay — then test it, then break it.
