What did OSIRIS-REx discover?
What did OSIRIS-REx discover?
Summary: Using data from NASA’s OSIRIS-REx mission, a University of Arizona-led team of scientists concluded that asteroids with highly porous rocks like Bennu should lack fine-grained material on their surfaces.
Why is Bennu the specific target of the Osiris-REx mission?
OSIRIS-REx is expected to return with its sample to Earth on 24 September 2023. Bennu was chosen as the target of study because it is a “time capsule” from the birth of the Solar System. Bennu has a very dark surface and is classified as a B-type asteroid, a sub-type of the carbonaceous C-type asteroids.
What kind of asteroid is Bennu?
potentially hazardous asteroid
Bennu is classified as a “potentially hazardous asteroid,” meaning the object is more than 460 feet (140 meters) wide and could theoretically come within 4.65 million miles of Earth. A 2014 study found that the asteroid had roughly a 0.037 percent chance of colliding with Earth between 2175 and 2199.
When was asteroid Bennu discovered?

What does OSIRIS-REx stand for?
OSIRIS-REx is an acronym for “Origins, Spectral Interpreta- tion, Resource Identification, and Security-Regolith Explorer .” It is scheduled to launch on Sept .
What is OSIRIS-REx doing now?
OSIRIS-REx remains in a frozen, safe-home orbit around Bennu, and the spacecraft is flying approximately 900 meters above the asteroid’s surface. Today, OSIRIS-REx celebrates four years since launch.
How is OSIRIS-REx getting back to Earth?
After nearly five years in space, NASA’s Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer (OSIRIS-REx) spacecraft is on its way back to Earth with an abundance of rocks and dust from the near-Earth asteroid Bennu.
Why is Bennu important?
From these 5 asteroids, Bennu was selected. These close encounters give Bennu a high probability of impacting Earth in the late 22nd century. Bennu’s size, primitive composition, and potentially hazardous orbit make it one of the most fascinating and accessible NEOs … and the ideal OSIRIS-REx target asteroid.
What if asteroid Bennu hit Earth?
If Bennu does impact Earth, it would create a crater between 10 to 20 times its size and cause an area of devastation that could reach 100 times the size of the crater, said Lindley Johnson, NASA’s planetary defense officer. The asteroid will make its next closest approach to Earth in 2135.
Why is OSIRIS-REx named that?
OSIRIS-REx is NASA’s first mission to bring a sample from an asteroid back to Earth. The name OSIRIS-REx is an acronym for the mission’s major concepts and goals, which stands for Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer.
