Washington, Jan 31 : NASA’s Mars 2020 Perseverance rover mission is set to complete a 470.8-million-kilometre next month as it is scheduled to land on Mars on February 18.
Launched on July 30 last year, the rover is currently closing that distance at 2.5 kilometres per second, NASA said.
Once at the top of the Red Planet’s atmosphere, an action-packed seven minutes of descent awaits — complete with temperatures equivalent to the surface of the Sun, a supersonic parachute inflation, and the first ever autonomous guided landing on Mars.
Only then can the rover search Jezero Crater for signs of ancient life and collect samples that will eventually be returned to Earth.
“NASA has been exploring Mars since Mariner 4 performed a flyby in July of 1965, with two more flybys, seven successful orbiters, and eight landers since then,” Thomas Zurbuchen, Associate Administrator for NASA’s Science Mission Directorate at the agency’s headquarters in Washington,” said in a statement.
“Perseverance, which was built from the collective knowledge gleaned from such trailblazers, has the opportunity to not only expand our knowledge of the Red Planet, but to investigate one of the most important and exciting questions of humanity about the origin of life both on Earth and also on other planets.”
Jezero Crater is believed to be the perfect place to search for signs of ancient microbial life.
Billions of years ago, the now-bone-dry 45-kilometre-wide basin was home to an actively-forming river delta and lake filled with water.
The rock and regolith (broken rock and dust) that Perseverance’s Sample Caching System collects from Jezero could help answer fundamental questions about the existence of life beyond Earth.
Two future missions currently in the planning stages by NASA, in collaboration with ESA (European Space Agency), will work together to bring the samples back to Earth, where they will undergo in-depth analysis by scientists around the world using equipment far too large and complex to send to the Red Planet.
The Mars 2020 mission is part of a larger programme that includes missions to the Moon as a way to prepare for human exploration of the Red Planet.
