What are the NASA JPL Mars rovers?
NASA's Jet Propulsion Laboratory (JPL) operates Mars rovers including Curiosity (landed August 2012, still operating) and Perseverance (landed February 2021, still operating). Both are autonomous-capable planetary rovers with documented autonomy upgrades over their mission lifetimes. They anchor the verified-at-scale planetary rover position in the autonomous space systems cohort.
What the rovers are
NASA JPL operates two active Mars rovers as of mid-2026.
Curiosity (Mars Science Laboratory) landed in Gale Crater on August 6, 2012 and has operated continuously for over a decade. Curiosity's mission is geological and astrobiological exploration; the rover has driven over 30 kilometers and produced a substantial science record across multiple mission extensions.
Perseverance (Mars 2020) landed in Jezero Crater on February 18, 2021. The rover targets astrobiology, sample collection for future return, and ingenuity helicopter scout operations (Ingenuity operated until early 2024). Perseverance has driven over 25 kilometers and produced a significant astrobiological and geological record.
Autonomy verification
Both rovers are autonomous-capable with documented upgrades over their mission lifetimes. Curiosity received the AutoNav autonomous driving capability via uplinked software updates; Perseverance launched with the more advanced AutoNav. Both rovers can plan and execute multi-meter drives without ground-in-the-loop intervention for each waypoint; ground operators set targets and constraints, and the rover executes within those.
The framework records both rovers at verified-at-scale planetary rover autonomy depth. The verification anchors are NASA primary-source mission records, JPL's published autonomy capability documentation, and the multi-year operational tail on both missions.
Cohort context
NASA JPL Mars rovers anchor the verified-at-scale planetary rover position in the autonomous space systems cohort. Lunar Outpost MAPP operates at the smaller commercial lunar rover sub-cohort. The framework reads planetary rover autonomy distinctly from spacecraft autonomy (lunar landers, orbital servicers) because the operational envelope is different (sustained surface operation across multiple Earth-Mars communication windows, vs. one-shot descent and landing sequences).
For the cohort umbrella, see What is autonomous space systems.
Frequently asked questions
- Are the rovers fully autonomous?
Both rovers are autonomous-capable within an operator-supervised envelope. Ground operators set drive targets and constraints; the rover plans and executes the drives autonomously using onboard AutoNav. Per the verified-vs-claimed framework, this is operator-supervised autonomy at the drive layer, verified at scale across multiple mission years.
- How long have the rovers been operating?
Curiosity has operated since August 2012 (over 13 years as of mid-2026). Perseverance has operated since February 2021 (over 5 years as of mid-2026). Both have had mission extensions and continue to produce science records.
- What is AutoNav?
AutoNav is NASA JPL's autonomous navigation capability for Mars rovers. The system plans and executes multi-meter drives using onboard hazard detection and path planning. Curiosity received AutoNav via uplinked software updates; Perseverance launched with the more advanced version. AutoNav significantly increases per-sol drive distance compared to ground-in-the-loop driving.
- Is Ingenuity still operating?
No. Ingenuity, the helicopter scout that flew with Perseverance, ended its mission in early 2024 after rotor damage during a flight. The framework records Ingenuity as ended-state; Perseverance continues to operate. Ingenuity's verified-at-scale Mars-aerial-autonomy record stands as the canonical first-flight worked example.
- Who builds the rovers?
NASA JPL is the primary integrator. Specific instrument and subsystem partners are documented per mission. The framework records NASA JPL as operator-and-customer of record on both rovers; instrument-level partnerships are tracked separately on the partnership graph.
- How does the rover autonomy compare to lunar landers?
Planetary rover autonomy operates across sustained surface operation; lunar lander autonomy operates during one-shot descent and landing sequences. The verification thresholds differ: rovers accumulate verified-at-scale records through multi-year drive logs; landers verify per-mission single-event landing outcomes. Both anchor verified-vs-claimed framings at distinct verification postures.
NASA JPL Mars rover operational status verified at NASA primary-source mission records depth. Curiosity and Perseverance both operating as of mid-2026 with multi-year sustained operational records. AutoNav capability documented in JPL published autonomy capability materials. Ingenuity ended in early 2024 after rotor damage. How DEPLOY verifies →
