NASA's OSIRIS REx spacecraft chooses Nightingale as the landing site on the Bennu asteroid: NASA's advanced spacecraft OSIRIS-Rex after nearly a year now has finalized Nightingale as its landing site on the Bennu asteroid. It will land and collect samples from the Bennu asteroid in August 2020 and depart it in 2021 to be later analyzed on it reaching earth in 2023.
Dante Lauretta is the principal investigator of OSIRIS Rex and a researcher at the University of Arizona in Tucson. He said that of the four sites chosen and given bird names like Sandpiper, Osprey, Kingfisher, and Nightingale, it is Nightingale where the OSIRIS REx craft is going to land in the Bennu asteroid.
It was after careful evaluating of all the four sites. From the excellent grained material of the sites and how easily the spacecraft can access them, Nightingale chosen as the most suitable one. It meets most of the criteria and will ultimately ensure the mission's success confirms Lauretta. Nightingale is located in a crater with a width of 140 meters or 460 feet on the north of the asteroid. It is smooth and with low temperatures to suit the landing of OSIRIS REx.
