The payload landed in the Australian outback as planned, capping a 6-year roundtrip journey to survey the asteroid Ryugu. The consequences may help clarify the solar system’s evolution, and the surprising complexities inside some of its most primitive asteroids. To understand Ryugu, it’s important to first understand its origins. These rare asteroids form under extremely high temperature conditions inside the solar system’s inner region. Regardless, the discovery revealed that the solar system’s earliest eras hosted some unexpected deep space interactions.
