Pallas, the largest B-type asteroid. Asteroid 101955 Bennu is a B-type asteroid which is the target of the OSIRIS-REx mission. The mission seeks to characterize the asteroid by mapping the surface, studying the Yarkovsky effect, and retrieving a sample of the asteroid to return in 2023. The spacecraft was launched in 2016 and has been at Bennu ...
Scientists anticipated getting a cupful but are still unsure how much was grabbed from the carbon-rich asteroid named Bennu, almost 60 million miles (97 million kilometers) away.
A sample from asteroid Bennu contains organic compounds usually found at midocean ridges on Earth, suggesting Bennu may have been part of an ancient ocean world. ... a large pristine asteroid ...
Bennu, a rather large rock with a diameter of around 500 meters, is the star of NASA's OSIRIS-REx mission which will see a small probe land on the asteroid, retrieve a sample, and then return from ...
Bennu was chosen as the target of study because it is a "time capsule" from the birth of the Solar System. [25] Bennu has a very dark surface and is classified as a B-type asteroid, a sub-type of the carbonaceous C-type asteroids. Such asteroids are considered primitive, having undergone little geological change from their time of formation.
The sample, collected from the 4.5 billion-year-old near-Earth asteroid Bennu in October 2020 by NASA’s OSIRIS-REx mission, arrived on Earth in a capsule on September 24, dropping from the ...
