Mars 2020/Perseverance

NASA and other space agencies (such as ESA) have been exploring Mars and gathering data for few decades now. According to this data Mars was once very different from the cold, dry planet it is today. Landers and orbiters have gathered evidence pointing to wet conditions billions of years ago. Scientist believe that these environmental conditions have lasted long enough to potentially support the development of microbial life.

NASA’s “Mars 2020/Perseverance” rover is designed to better understand the geology of Mars and seek signs of ancient life. The best method to analyse Martian rock samples would be to bring it back to earth and analyse them here on Earth, hence this mission will collect and store a set of rock and soil samples that could be returned to Earth in the future.

It will also test new technology to benefit future robotic and human exploration of Mars. Such as the autopilot system called Terrain Relative Navigation which will avoid potentially hazardous terrain.

Perseverance landed on Mars/Jezero Crater’s ancient lake-delta system containing carbonates and minerals. Scientist believe that this lake-delta will preserve fossilized signs of ancient life.

Perseverance carried seven instruments to Planet Mars.

Rover Size and Dimensions

Perseverance Rover is about 10 feet long (not including the arm), 9 feet wide, and 7 feet tall (about 3 meters long, 2.7 meters wide, and 2.2 meters tall).


Perseverance carried with it; a 2 kg helicopter named “Ingenuity’ which will become the first aircraft to attempt powered flight on another planet. This solar powered drone will take arial photographs of the Jezero Crater.
