After a seven months’ journey from Earth, the NASA Perseverance is in its final stretch towards destination Mars.
About the Perseverance rover:
- Launched on July of 2020.
- It is expected to touch down on Mars at the Jezero Crater.
- The primary task of Perseverance is to seek signs of ancient life and collect samples of rock and reglolith to possibly return these to Earth.
- Perseverance is fueled by electrical power by using heat of plutonium’s radioactive decay.
- NASA Perseverance gets shape memory alloys to remain steady on surface of Mars.
- Armed with drills, cameras and lasers, Perseverance is set to explore Mars.
Why is this mission significant?
- Perseverance will carry a unique instrument, MOXIE or Mars Oxygen ISRU Experiment: which for the first time will manufacture molecular oxygen on Mars using carbon dioxide from the carbon-dioxide-rich atmosphere (ISRU means In Situ Resource Utilization: or the use of local resources to meet human needs or requirements of the spacecraft).
- It 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.
Previous Mars Missions by NASA:
- NASA has been sending rovers on Mars since 1997 when the Mars Pathfinder Mission was initiated.
- As the mission turned out to be successful, NASA decided to continue going to Mars to find evidence.
- Second time, the space organization sent twin rovers, Spirit and Opportunity to Mars in 2003.
- The third attempt was by sending Curiosity in 2012.
