Asteroid Bennu: A Gateway to Understanding Life’s Origins
Asteroid Bennu: A Gateway to Understanding Life’s Origins About Asteroid Bennu Bennu is a small, near-Earth asteroid that follows a six-year orbit around the Sun, periodically coming close to Earth. It is classified as a carbonaceous (C-type) asteroid, meaning it is rich in carbon-containing compounds and may hold clues to the early solar system. Scientists believe Bennu originated from a much larger carbon-rich asteroid that broke apart 700 million to 2 billion years ago. NASA's OSIRIS-REx Mission The OSIRIS-REx spacecraft was launched by NASA in 2016 to study Bennu and collect surface samples. In 2020, the spacecraft successfully retrieved samples using its robotic arm and stored them in a return capsule. In 2023, these samples were delivered back to Earth for analysis. Scientific Findings from Bennu’s Samples The samples contained essential life-building compounds , such as: Amino acids – Fundamental components of proteins. Nucleobases – Key building blocks of DNA and RNA. W...
