Explanation: 

Detailed explanation-1: -NASA’s OSIRIS-REx is an ongoing mission that visited and collected a sample from asteroid 101955 Bennu, with the aim of returning the sample to Earth in 2023. OSIRIS-Rex launched on Sept. 8, 2016, and arrived at asteroid Bennu on Dec.

Detailed explanation-2: -A series of maneuvers beginning in July 2023 will bring OSIRIS-REx even closer, to 155 miles (250 kilometers) off the surface, close enough to release its sample capsule for a precision landing – via parachute at the Air Force’s Utah Test and Training Range in the Great Salt Lake Desert.

Detailed explanation-3: -Hayabusa2 is a Japanese spacecraft that studied asteroid Ryugu, collected samples, and brought them to Earth for analysis.

Detailed explanation-4: -OSIRIS-REx asteroid samples will land on Earth in 2023 and scientists can’t wait. Returning to Earth is only the beginning of the journey for these pieces of asteroid Bennu.
