Perseverance

Perseverance landed in Jezero Crater in February 2021 because scientists believe it was once an ancient lakebed and river delta. This environment is highly likely to have preserved signs of ancient microbial life in the form of fossilized stromatolites or other biosignatures. The crater's diverse geological features make it an ideal spot for sample collection.

Perseverance uses a specialized drill to extract core samples from Martian rocks, which it then seals inside ultra-clean titanium tubes. These sample tubes are currently being cached on the surface of Jezero Crater for a future Mars Sample Return mission. The goal is for another spacecraft to retrieve them and bring them back to Earth for comprehensive laboratory analysis.

Yes, Perseverance carried the Ingenuity helicopter to Mars, which became the first aircraft to achieve powered, controlled flight on another planet in April 2021. Ingenuity acted as an aerial scout to help plan driving routes for the rover, demonstrating the viability of aerial exploration on Mars. Though Ingenuity's mission eventually ended due to rotor damage, it vastly exceeded its original five-flight demonstration goal.

While both rovers share a similar chassis and power source, Perseverance is equipped with entirely different scientific instruments focused on astrobiology and caching samples. It features a more advanced coring drill and an internal sample handling system that Curiosity lacks. Furthermore, Perseverance carries microphones and terrain-relative navigation technology that allowed it to land much more precisely than Curiosity.
