NASA's Mars 2020 Perseverance rover

NASA has recently launched its Mars 2020 Perseverance a fourth-generation rover.
This is the world’s third and final Mars launch of the summer (UAE’s Hope Probe and China’s Tianwen-1)
This Perseverance rover will carry a unique instrument, MOXIE or Mars Oxygen ISRU Experiment.
It is for the first time will manufacture molecular oxygen on Mars using carbon dioxide from the carbon-dioxide-rich atmosphere.
If oxygen can be successfully extracted on Mars in some significant scale, this can have two direct advantages:
- The oxygen can be used for human visitors to Mars, and second, the oxygen can be used to manufacture rocket fuel for the return journey.
Perseverance will carry Ingenuity, the first-ever helicopter to fly on Mars.
This is the first time NASA will fly a helicopter on another planet or satellite.
Perseverance is the planned first step to bring back rock samples from Mars for analysis in sophisticated laboratories on Earth.
