NASA also has successfully sent three landers - Pathfinder, Phoenix and InSight. Both China and the United Arab Emirates launched spacecrafts to the planet in July. Aboard a rocket Atlas 541, that will take off if everything goes according to plan the 13.50 uk time , travel Perseverance , a rover the size of a small vehicle with a similar appearance to its predecessor, Curiosity, active in the red planet since 2012.
NASA's Perseverance will find answers to many important questions related to astrobiology, the biggest question of which is: Is life on Mars possible?
Since NASA's first Mars rover Sojourner landed in 1997, the agency has sent two others - Spirit and Opportunity - that have explored the geology of expansive Martian plains and detected signs of past water formations, among other discoveries. This will help determine the future spacesuits that astronauts will wear on missions.
When on Mars, the SHERLOC instrument will primarily study how long the materials can serve before they begin to disintegrate in the local environment, which is influenced by the surrounding radiation.
The car-sized six-wheeled robotic rover, which will launch atop an Atlas 5 rocket from the Boeing-Lockheed joint venture United Launch Alliance, also is scheduled to deploy a mini helicopter on Mars and test out equipment for future human missions to the fourth planet from the sun.
After landing on Mars, its small helicopter Ingenuity will be released. Never before has a rotorcraft been flown anywhere except on Earth's atmosphere. This helicopter will rise 10 feet above the surface and will go up to 6 feet at a time. It will help expand our horizons in every corner of the universe. "But we do know that Mars at one point in its history was habitable", NASA Administrator Jim Bridenstine said on the eve of the launch. The most important contribution is MEDA (Mars Environmental Dynamics Analyzer), a sophisticated weather station developed mainly by the National Institute of Aerospace technology (INTA) and the Center of Astrobiology (CAB). He has done so eight times, starting with Vikings in 1976.
