NASA asteroid sampling spacecraft to study Bennu’s “chaos”



The moment Osiris-Rex met Bennu.

October 2020, National Aeronautics and Space Administration (NASA) The Osiris-Rex spacecraft took a bite of the asteroid Bennu. Before Osiris-Rex returns to Earth to offer bounty, it will revisit the scene of the robbery. The spacecraft will perform a Bennu (Bennu) last very close flyby on Wednesday to discover “the degree of chaos it has caused.”

Osiris-Rex was a bit greedy during the sample collection process, Gravel spillage It must be stored faster than expected. It left marks on the asteroid.

NASA said: “After Bennu’s surface was severely disturbed by the sample collection event, the Osiris-Rex team decided to add the last flyover.” “During the landing, the spacecraft’s sampling head sank 1.6 feet into the asteroid’s surface (48.8 cm), and pressurized nitrogen gas was launched at the same time.” The launched thruster pushed Osiris-Rex away, which also disturbed the water surface.

NASA has scheduled the flyover to take place on April 7, with the goal of taking images of the collection site at a close distance of 2.3 miles (3.7 kilometers).

Osiris-Rex will continue to wander around Bennu until May 10, when it will begin a two-year journey back to Earth. The Bennu fragments will be delivered to the scientists via the sample return module discarded by the spacecraft.

At the same time, NASA will be able to compare the before and after images of the sample site to understand how big the tattoo Osiris-Rex left on Bennu.
