description Mars 2020 (Perseverance) Overview

NASA's Mars 2020 mission landed Perseverance in Jezero Crater in February 2021 to investigate an ancient environment that may once have supported microbial life. Its scientific work connects the crater's geology with the search for possible signs of past organisms. A defining task is collecting and sealing rock and soil samples for a potential future return to Earth, where laboratories could examine them using equipment unavailable on the rover. Perseverance also carried the Ingenuity helicopter to Mars, where it achieved the first powered, controlled flight on another planet.

That demonstration added an aerial element to a mission centered on surface exploration. The rover's measurements and technology demonstrations also inform preparations for future human exploration. Mars 2020 particularly suits study of how geological investigation and sample collection can work together, while sample return remains a separate undertaking.

help Mars 2020 (Perseverance) FAQ

When did NASA's Perseverance rover land on Mars?

Perseverance landed on Mars on February 18, 2021, in Jezero Crater, an ancient lakebed chosen for its potential to preserve signs of past microbial life. The landing used the same 'sky crane' system previously employed by the Curiosity rover in 2012.

What is the Ingenuity helicopter on Mars 2020?

Ingenuity is a small solar-powered drone helicopter that traveled to Mars attached to the underside of Perseverance. It performed the first powered, controlled flight on another planet on April 19, 2021, and flew dozens of additional missions before its rotors were damaged in January 2024.

Where on Mars did Perseverance land?

Perseverance landed in Jezero Crater, a roughly 45-kilometer-wide impact crater north of the Martian equator. Scientists chose the site because orbital imagery showed what appeared to be an ancient river delta, an ideal environment for preserving biosignatures.

Is Perseverance related to Curiosity?

Yes, Perseverance was built using many of the same spare parts and design as Curiosity, the rover that landed on Mars in 2012 at Gale Crater. Perseverance is more capable, however, and carries different instruments optimized for astrobiology and sample caching.
