The US space agency NASA has released a series of photos from its Osiris-Rex spacecraft that shows a series of flybys of the 1,600-foot-wide asteroid Bennu. The Osiris-Rex (Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer) spacecraft arrived in orbit around Bennu, which orbits the sun between Earth and Mars, back in early December. The craft has a number of tasks on its highly important mission, including measuring Bennu's size and trajectory with extreme accuracy, because NASA's Jet Propulsion Laboratory gives Bennu a cumulative 1-in-2,700 chance of impacting Earth between 2175 and 2199, Sputnik reported. Osiris-Rex also plans on collecting a sample from Bennu's claylike surface and shipping it back to Earth, as NASA scientists believe the alien soil "may record the earliest history of our solar system. Bennu may contain the molecular precursors to the origin of life and the Earth's oceans. Bennu is also one of the most potentially hazardous asteroids, as it has a relatively high probability of impacting the Earth late in the 22nd century," the mission page notes. In the month since its arrival, Osiris-Rex has performed a preliminary survey of Bennu, conducting three flyovers of the asteroid's north pole and one each of its equator and south pole," Osiris-Rex researchers said in a December 31 statement. "The data gathered during these flybys allowed the mission team to more precisely estimate Bennu's mass so that the spacecraft could go into orbit around the asteroid." Source: Sputnik News
Osiris-REX enters close orbit around asteroid Bennu Tucson AZ (SPX) Jan 01, 2019 At 2:43 p.m. EST on December 31, while many on Earth prepared to welcome the New Year, NASA's OSIRIS-REx spacecraft, 70 million miles (110 million kilometers) away, carried out a single, eight-second burn of its thrusters - and broke a space exploration record. The spacecraft entered into orbit around the asteroid Bennu, and made Bennu the smallest object ever to be orbited by a spacecraft. "The team continued our long string of successes by executing the orbit-insertion maneuver perfectly," said ... read more
