The pristine sample of a 4.5 billion-year-old asteroid delivered to Earth last month contains water and high amounts of carbon, according to NASA. Why it matters: That composition suggests life’s building blocks may be found within the asteroid, the space agency said.
The Osiris-Rex spacecraft picked up the Bennu materials in October 2020, using a daring manoeuvre to approach and then “high-five” the asteroid – an operation performed while 330 million km (205 million miles) from Earth.
OSIRIS-REx was a NASA asteroid-study and sample-return mission that visited and collected samples from 101955 Bennu, a carbonaceous near-Earth asteroid.
A sample of material collected from the surface of the near-Earth asteroid Bennu has been found to contain abundant water and carbon, the US space agency NASA said, offering more evidence for a theory that life on Earth was seeded from outer space
Material collected from the asteroid acts as a time capsule from the earliest days of our solar system
Bennu is a small near-Earth asteroid that passes close to Earth every six years. A 4.5 billion-year-old relic of our solar system’s early days, asteroid Bennu has seen it all. Bennu’s current composition, according to scientists, was established within 10 million years of the formation of our solar system
The mission has provided an “abundance” of samples — the goal of the OSIRIS-REx sample collection was to collect 60 grams of asteroid material. But scientists disassembling the sample return hardware found bonus particles covering the outside of the collector head, canister lid and base. The total sample weight has been estimated at around 250 gms.माँ
