Perseverance
NASA rover searching for signs of ancient Martian life.
Its main goals are to search for signs of ancient life, study the planet's geology and climate, and collect rock and regolith samples for possible return to Earth by a future mission.
- Operator
- NASA / Jet Propulsion Laboratory
- Power source
- Radioisotope thermoelectric generator
- Key achievement
- First powered flight on another planet (via Ingenuity helicopter)
Lore & Background
The rover has completed multiple science campaigns: the first, 'Crater Floor,' involved an arching drive southward to the Séítah unit and collection of the first core sample. The second campaign, 'Fan Front,' included travel to 'Three Forks' and ascent of the ancient delta.
Reader's Guide
Perseverance represents a critical step in the Mars Exploration Program's long-term goal of returning samples from Mars to Earth. Its mission was shaped by the 2011 Planetary Science Decadal Survey, which prioritized a NASA-ESA Mars Sample Return campaign, and by NASA's 2012 announcement of a new rover mission following Curiosity's success. The rover's science objectives—looking for habitability, seeking biosignatures, caching samples, and preparing for humans—directly support this campaign. Its discoveries include evidence of igneous rocks that interacted with water, an ancient lake environment at Wildcat Ridge, and possible biosignatures in the Cheyava Falls rock. By caching samples for potential future retrieval, Perseverance lays the groundwork for answering whether life ever existed on Mars.
Did You Know?
- Perseverance landed in Jezero Crater, chosen for its ancient river delta that may preserve evidence of past microbial life.
Frequently Asked Questions
What is Perseverance's primary mission?
The rover's core objectives are to hunt for traces of ancient microbial life, characterize Mars's geology and atmospheric history, and gather sealed rock and soil samples that a future mission could bring back to Earth.
Why was Jezero Crater chosen as the landing site?
Jezero Crater was selected because it contains an ancient river delta, a geological feature that could have trapped and preserved biological signatures from billions of years ago. This makes it one of the most promising locations on Mars for finding evidence of past life.
What is Perseverance's most notable first?
Perseverance enabled the Ingenuity helicopter to complete the first powered, controlled flight on another planet, a milestone never achieved before in robotic exploration. This proved that sustained flight is possible even in Mars's thin atmosphere.
What happens to the samples Perseverance is collecting?
The sealed rock and regolith tubes the rover caches are intended to be retrieved by a later Mars Sample Return mission and delivered to laboratories on Earth for detailed analysis. As of now, no return vehicle has been launched, so the samples remain stored on the Martian surface.
