(Photo: NASA) Agence France-Presse reported that NASA’s spacecraft “Osiris-Rex” will land in the Utah desert in the United States on the 24th to collect the largest collection of The asteroid sample was brought back to Earth, bringing the climax to the end of the seven-year voyage. Scientists have high hopes for the sample, saying it will provide a better understanding of the formation of the solar system and how the Earth became habitable. The final stage of Osiris’ return journey through the Earth’s atmosphere will be dangerous, and NASA hopes it will make a soft landing at a military test site in northwest Utah at regarding 9 a.m. local time. Osiris was launched from Cape Canaveral, Florida, in 2016. The probe landed on the asteroid Bennu four years later and collected regarding 9 ounces from the rock surface. (250 grams) of dust. NASA Administrator Bill Nelson said even this small amount should “help us better understand the types of asteroids that may threaten Earth” and make it easier to understand “the earliest history of our solar system.” NASA scientist Amy Simon said that bringing back this sample is indeed of historic significance. This will be the largest sample brought back to Earth since the Apollo moon rocks. But she also admitted that the return of the Osiris would require “dangerous operations.” Osiris plans to release the capsule from an altitude of more than 67,000 miles (108,000 kilometers) regarding four hours before landing. The final 13 minutes of the fiery journey through the atmosphere will take place as the capsule hurtles downward at more than 27,000 miles per hour and at temperatures as high as 5,000 degrees Fahrenheit (2,760 degrees Celsius). U.S. military sensors will monitor its rapid descent, and two parachutes in succession will slow it down. Once the process is not carried out correctly there will be a “hard landing”. If it looks like the target area (37 x 9 miles) will be missed, NASA controllers may decide at the last minute not to release the capsule, allowing the probe to retain its cargo and orbit the sun once more. Scientists will have to wait until 2025 to attempt a new landing. But if the tire-sized capsule lands successfully in Utah, a team wearing protective masks and gloves lowers it into a net and then airlifts it by helicopter to a nearby makeshift “clean room.” NASA hopes to complete this work as quickly and carefully as possible to avoid contaminating the samples with desert sand and affecting the test results.
