NASA’s Mars 2020 Rover Sending Back of an Old plate with a Martian Meteorite to Use as Target Practice

NASA’s Mars 2020 rover will carry a piece of an ancient Martian meteorite to return to its planet of origin. Ancient parts of Mars were at rest on the Earth as meteorites, scientists have determined has blown out of the surface of Mars millions of years. Now, the scientists have decided to send a piece known as Sayh al Uhaymir 008 (SAU008) aboard the rover, NASA announced on Tuesday.The soon-to-be meteorite passenger is going to be used as target practice for a laser technology that is designed to examine the rock features on Mars as fine as a human hair. The laser of the instrument known as SHERLOC (short for Scanning Habitable Environments with Raman and Luminescence for organics and Chemicals) study of the Martian rock, but scientists need a test area first. Often, instruments such as SHERLOC are tested on rocks, metal, and glass placed on the Red Planet, and even the space-suit material, which allows SHERLOC analyze how the space suits to survive the Martian environment. But, scientists from the California Institute of Technology Jet Propulsion Laboratory of the thinking of using a piece of Mars itself could prove even more effective for target practice. Rohit Bhartia of NASA’s Mars 2020 mission is the holder of a slice of a meteorite, scientists have determined came from Mars. NASA/JPL-Caltech follow this story and more by subscribing now“We look at things on a fine scale that minor distortions caused by temperature changes, or even the rover sit in the sand, can request that we correct our aim,” Luther Beegle, principal investigator for SHERLOC at the Jet Propulsion Laboratory, said in a statement. “By studying how the instrument sees a fixed target, we can understand how he is going to see a piece of the Martian surface.”SHERLOC operates using the same techniques that forensic scientists use. For example, some chemicals exposed to ultraviolet light reveal some glow—like that under a black light. SHERLOC will use a similar process through the taking pictures of the Martian rock and mapping the chemical that “glimmer” to indicate the presence of life.“This kind of science requires the texture and organic chemicals—two things that our target meteorite will provide,” Rohit Bhartia, Jet Propulsion Laboratory, and SHERLOC deputy principal investigator, said in a statement. The science instruments of NASA’s Mars 2020 rover mission. NASA hunting for the perfect meteorite to send to Mars has been carefully planned. There are about 200 Martian meteorites known on Earth, and he had to find one that could survive take-off and landing. In Addition, it should be hard, not flaky, and have chemical characteristics of test SHERLOC. The one they have chosen, SaU008, was discovered in the sultanate of Oman in 1999. The sample is robust, according to researchers, and it was also ideally to win it to use it as a test of the sample of Caroline Smith, the senior curator of meteorites at London’s Natural History Museum.There will be two pieces of SaU008 for the tests on Earth and on Mars. The sample to go to Mars, will be the first to return to the planet’s surface, but not the first on a return trip to Mars in general. Zagami, another Martian meteorite, is still floating in Mars’s orbit on the now-defunct Mars Global Surveyor. A second instrument SuperCam on Mars 2020 rover will also select a sample for target practice. Smith said in a statement: “This is a first for us: the sending of one of our samples back to the house for the benefit of science.”
