Hayabusa2

Asteroid Ryugu: All five canonical bases of DNA and RNA were identified in samples returned from it by the Hayabusa2 spacecraft, a finding that strengthens the hypothesis that carbonaceous asteroids contributed to the starting materials for life on Earth.

New research on Ryugu samples, combined with findings from the asteroid Bennu, from which the samples were brought to Earth, strengthens the hypothesis that carbonaceous asteroids provided the early Earth with important starting materials for the chemistry of life.

New observations using ESO's Very Large Telescope (VLT) have revealed that the asteroid is only 11 metres in diameter – almost a third smaller than previously estimated – and completes a rotation every five minutes, faster than expected. The image shows an updated size comparison between the asteroid and the spacecraft. Credit: ESO/M. Kornmesser. Asteroid: T. Santana-Ros et al. Hayabusa2 model: SuperTKG (CC-BY-SA).

Will Hayabusa 2 succeed in landing? Its target is a tiny, faster-than-expected asteroid

The asteroid Bennu is a time capsule of materials that testify to its origin and the changes that have occurred over billions of years.
