On the rover’s mast, two science instruments provide high-resolution imaging and three types of spectroscopy for characterizing rocks and soil from a distance, also helping to determine which rock targets to explore up close. Two science instruments mounted on the rover’s robotic arm are used to search for signs of past life and determine where to collect samples by analyzing the chemical, mineral, physical, and organic characteristics of Martian rocks.
Subsequent NASA missions, in cooperation with ESA (European Space Agency), would send spacecraft to Mars to collect these sealed samples from the surface and bring them to Earth for in-depth analysis using powerful laboratory equipment too large to take to Mars. increases the likelihood that especially valuable samples will be accessible for retrieval. Perseverance will likely create multiple “depots” later in the mission for this purpose. Throughout its exploration of the region, the rover will collect promising samples, sealing them are tubes and storing them in its chassis until Perseverance deposits them on the Martian surface to be retrieved by a future mission. The rover carries an entirely new subsystem to collect and prepare Martian rocks and sediment samples that includes a coring drill on its arm and a rack of sample titanium tubes in its chassis. Perseverance is investigating Jezero Crater – a region of Mars where the ancient environment may have been favorable for microbial life – probing the Martian rocks for evidence of past life. A key objective for Perseverance’s mission on Mars is astrobiology, including the search for signs of ancient microbial life. analyzed rover images taken shortly after landing that show distant cliff faces at the edge of the delta. Earlier orbital images showed that the crater contains an ancient river delta that was deposited by water flowing into a lake billions of years ago. The Perseverance Mars rover is part of NASA’s Mars Exploration Program, a long-term effort of robotic exploration of the Red Planet. The Perseverance rover landed in Jezero crater, Mars, in February 2021.
