Ancient & Dangerous: NASA Hopes to Examine Bennu Asteroid Sample
15:49 24.09.2023 (Updated: 15:50 24.09.2023) Launched in 2016, the Osiris-Rex mission arrived at asteroid Bennu on Dec. 3, 2018. The asteroid is an antiquity from the Solar System's early days and has seen more than 4.5 billion years of history. According to scientists, Bennu's present-day composition was established within 10 million years of our system's formation.
NASA's Osiris-Rex mission will return to Earth on September 24, bringing particles from Bennu – an asteroid believed to be one of most dangerous rocks in outer space.
Experts hope to study the samples as soon as possible and shed some light on the formation of the planets and maybe even offer insights into the start of biological life on Earth.
