Past cheers and celebrations for the perfect landing now the real work of the Perseverance rover begins arrived on Mars after a journey that lasted months. The departure was on June 30, 2020. It is not the first vehicle that NASA sends to the red planet, it is the fifth, but it is the one with the largest and most innovative means. The goal of all missions to Mars was to look for traces of life on the planet, past or present traces.
Perseverance, NASA’s Mars 2020 mission rover, does it in the area of ​​the Jazero crater, the basin of an ancient lake, about 500 meters deep, which could have traces of past life.
The first images have already arrived on Earth immediately after the arrival which is already a great success given that only 40% of the vehicles that have so far attempted to arrive on Martian soil have succeeded in the undertaking.
«Perseverance is the most ambitious rover among NASA robots, whose scientific goal is find out if there was ever life on MarsSaid the head of the Directorate of Scientific Missions of the American space agency, Thomas Zurbuchen. The chosen crater would have formed billions of years ago, perhaps due to the impact of an asteroid, then became a lake and eventually lost water when the planet’s climate changed.
The rover aims to collect, with a drill it has installed, rock and soil samples that will be left in a point for recovery by a future mission. Mars Sample Return, not yet determined. It has seven tools with advanced technologies to study the surface of Mars. Perseverance has a working time span of one Martian year, 687 days. There is to guide him the Ingenuity helicopter, a drone. There are microphones that will allow for the first time to hear the sounds of Mars. The Italian micro-reflector Lara (Laser Retroreflector Array) will allow to study the internal structure of the red planet.
Before Perseverance there were Sojourner arrived in 1997 with the Mars Pathfinder mission, then the twin rovers Spirit e Opportunity, of the Mars Exploration Rover mission arrived in January 2014, which remained active for 6 and 15 years. Last came Curiosity, active since August 6, 2012. She is not alone on Mars. A few weeks ago, the Arab Emirates arrived with the Hope orbiter, then China with Tianwen-1.
