The Hayabusa 2 spacecraft brought back samples from Ryugu in 2020, and an analysis of a tiny portion of those samples has revealed key ingredients for life
spacecraft is on the way back from another asteroid called Bennu with more than 400 grams of asteroid dust, and should arrive in September 2023.Voyage across the galaxy and beyond with our space newsletter every month.
“We strongly expect that, in addition to uracil, other nucleobases and further interesting molecules are detected in Bennu samples since much larger abundance would be available for lab analyses,” says Oba.in our solar system, so if these compounds are present there they were almost certainly also present on early Earth.
