scientists finetune odds asteroid hitting earth

This delivery will allow scientists to examine asteroid material with all the advanced equipment available in terrestrial laboratories.Scientists don't have to be able to access the sample material in order to study the two-and-a-half years of spacecraft observations.

OSIRIS-REx will deposit a sample capsule on September 2023. The spacecraft and its valuable cargo left the asteroid in May and returned to Earth. OSIRIS-REx took a sample from Bennu for its safekeeping. The new research team was able to refine their understanding of the movement and location of the space rock for almost two and a quarter years using this data.October 2020 was the culmination of the spacecraft's trip to the asteroid. This allowed us to see a wide range of angles.The spacecraft kept track of its position relative to Earth and the asteroid throughout that period. We were able go into orbit, and we were also able leave orbit. He is also the principal investigator of OSIRIS-REx, and was an author of the new research. It was then placed in orbit around the asteroid Bennu, December 2018.The spacecraft spent almost two-and-a-half years studying the space rock orbiting it, hovering above and inspecting every aspect of the rock.Dante Lauretta (University of Arizona planetary scientist), said that the trajectory of the spacecraft was 'really amazing' and was compared to a hummingbird. Davide Farnocchia is the study's lead author.OSIRIS-REx, also known as Origins Spectral Interpretation and Resource Identification, Security-Regolith Explorer, was launched in September 2016 by OSIRIS-REx. 'I believe that the overall situation has improved.'Precision is importantOverall, I believe that the situation has improved.

Asteroid trajectory calculations can be improved by the research, which could help reduce concerns about possible impacts from other asteroids.'The impact probability went up just a bit, but it's still not a significant difference, the impact probability remains pretty much the same,' Davide Farnocchia (lead author), who works at NASA's Center for Near Earth Object Studies, California, stated during a news conference on Wednesday, August 11. (Image credit: NASA/Goddard/University of Arizona)Although technically, this is a slight increase in risk, the scientists behind the research don't believe it will have any significant impact. NASA stated that while it is a higher risk than previous estimates, it is still a small change to an already minimal risk.Related: NASA spacecraft leaves Bennu asteroid to bring parts to EarthContinue reading: OSIRIS-REx team creates Bennu photosOSIRIS-REx captured an image of Bennu, the asteroid. NASA reported that estimates made before OSIRIS REx reached the space rock put the cumulative probability for a Bennu-impact between 2175-2199 at 1 in 2,700. Experts studying possible space rock impacts with Earth were able to get a detailed view of the asteroid and fine tune their models of Bennu’s future.Scientists behind new research are now confident that the asteroid's total probability of impact through 2300 is only 1 in 1,750. NASA scientists believe that if the possibility of Bennu, an asteroid hitting Earth in a few years is keeping you awake at night you can now rest easier.OSIRIS-REx, the OSIRIS spacecraft of the agency, spent over two years orbiting this space rock.
