C
Asteroid Bennu
D

Explanation: 

Detailed explanation-1: -The brief landing Thursday is the second time Hayabusa2 has touched down on the desolate asteroid Ryugu, some 300 million kilometres (185 million miles) from Earth.

Detailed explanation-2: -Hayabusa2 is a Japanese spacecraft that explored asteroid Ryugu (162173) from June 2018 to November 2019. It dispatched a series of landers and a penetrator, and it collected multiple samples from the asteroid.

Detailed explanation-3: -The Hayabusa-2 probe brought 5.4 grams of rocks and dust from the asteroid Ryugu to Earth in December 2020. Here is what its study has revealed. How did the Earth, believed to have been covered in bubbling oceans of magma billions of years ago, transform into the ‘blue planet’ and become covered in water?

Detailed explanation-4: -The return capsule of the Hayabusa2 mission-about the size and shape of a wok-parachuted to a landing in the red desert sand of Woomera, Australia, in the early morning of 6 December, after a nearly 5.3-billion-kilometer trip to the asteroid Ryugu.

Detailed explanation-5: -Hayabusa2 arrived at Ryugu on June 27, 2018, collected samples from the asteroid during two touchdowns in 2019, and delivered the sample capsule back to the Earth on December 6, 2020. After delivering the capsule, the spacecraft continued on to a new mission.
