Japan’s Hayabusa2 mission to asteroid Ryugu. Credit: JAXANew research has revealed important new clues as to how the inner Solar System, including Earth, acquired its water and organic-rich components – the essential building blocks for all life.has undertaken a detailed study of eight particles returned to Earth from asteroid ‘Ryugu’ by thespacecraft Hayabusa2.
In fact, the material contains a lot of water and organic matter. OU experts were able to confirm that the Ryugu samples are very similar to meteorites of the CI chondrite group. These are considered the most important single meteorite group because they have a composition that matches that of our Solar System. They were also able to show that CI chondrites have been contaminated by their interaction with the terrestrial environment.
“When Asteroid Ryugu was surveyed in space by the Haybusa2 spacecraft it looked as though the results from the mission might be a bit disappointing. It seemed that materials from which the asteroid was composed had been heated to a high temperature and much of the water stored in them had been lost to space.

A pristine record of outer Solar System materials from asteroid Ryugu’s returned sample - Nature AstronomyThe sample taken from carbonaceous asteroid Ryugu and brought back to Earth by the Hayabusa2 spacecraft contains outer Solar System-derived materials uncontaminated by terrestrial processes. Even CI carbonaceous chondrites, despite their closeness to solar abundances, are not pristine.

Lunar Rocks Have Earth's Noble Gases Trapped Inside. More Evidence That the Moon Came From the EarthPiecing together the history of the Solar System from the traces left behind isn’t easy. Bit by bit, however, we’re working it out. This month, new research examining the composition of lunar meteorites offers compelling evidence that the Moon and the Earth were formed from the same material, perhaps in the aftermath of a cataclysmic … Continue reading 'Lunar Rocks Have Earth's Noble Gases Trapped Inside.
