On September 8, NASA will introduce the OSIRIS-REx spacecraft on a mission to an asteroid and come back a model of it back to Earth — NASA’s primary task of this type. NASA hopes to learn more concerning the untimely configuration of the solar system and, perhaps, the origin of life. OSIRIS-REx, which situate for Origins Spectral Interpretation Resource Identification Security – Regolith Explorer, will travel to a near-Earth asteroid known as Bennu. Bennu is of particular interest because it’s a B-type asteroid, which means there’s a good possibility that it’s covered in carbon fabric and organics, the structure blocks of life. Bennu is confidential as a Potentially Hazardous Asteroid and has a high probability of crash our planet in the 22nd century. Researching Bennu currently could be helpful down the road in the happening that prospect scientists and engineers require to expand an impact mitigation mission. Upon arrival at Bennu in 2018, the spacecraft will recognize a scientifically attractive section of the rock and use its robotic arm to imprison a 2.1-ounce sample. OSIRIS-REx is scheduled to leave the asteroid in 2021, and return the model to Earth in 2023. Scientists desire to get their hands on an asteroid because these are primitive rocks that stand for the early building blocks of our solar system, and probably of life. In general, it’s supposed that asteroids are just available debris from the formation of the planets in our solar system, created billions of years ago.
Researching them could disclose details concerning our premature cosmic history and how planets form. There’s also an attractive hypothesis, known as panspermia, that microbial life was carried to Earth by asteroids, meteoroids, comets or other orbiting planetary bodies. And the best thing about asteroids, from astronauts’ sight, is that they probable haven’t changed much since their formation. On Earth, we have recycling processes like erosion that constantly change our surface geology. Asteroids don’t have things like oceans, wind, rain or tectonic plates to wipe their history away. Once OSIRIS-REx arrives at Bennu it will need to recognize the most scientifically attractive section to bring home. In an attempt to test the panspermia hypothesis, NASA’s goal is to home in on a part that contains organic fabric, one of the building blocks of life. Dissimilar minerals and molecules have unique “spectral signatures.” OVIRS will gauge how the asteroid surface interacts with visible and near-infrared light and match the outcome to known spectral signatures to decide the work of that section. OSIRIS-REx will demeanor a detailed survey of Bennu for over a year to create a map of potential sample sites. After NASA selects the last site, the spacecraft will move in to the asteroid for example extraction. OSIRIS-REx will make contact with the surface for about 5 seconds and shoot a burst of nitrogen gas at the asteroid’s surface. This burst of gas will stir up small pieces of rock, which will then be collected. If the primary effort fails, OSIRIS-REx has sufficient stored nitrogen gas for two additional attempts. The sample will be stored in the spacecraft’s Sample Return Capsule (SRC).
