Remote sensing data sheds light on when and how asteroid Ryugu lost its water
Last month, Japan’s Hayabusa2 mission brought home a cache of rocks collected from a near-Earth asteroid called Ryugu. While analysis of those returned samples is just getting underway, researchers are using data from the spacecraft’s other instruments to reveal new details about the asteroid’s past.

Samples from Ryugu Asteroid Revealed After Delivery to Earth
Mashable reports: The Japan Aerospace Exploration Agency showed off a collection of samples from the asteroid Ryugu on Thursday following the return of the Hayabusa2 probe. The black, gravelly samples from Ryugu contain a whole bunch of small chips collected from the asteroid’s subsurface… Normally, space rocks like these are collected after they enter Earth’s atmosphere at surface-scorching speeds. These samples…
An Asteroid the Size of a Dwarf Planet Is Lurking In Our Solar System
Long-time Slashdot reader fahrbot-bot summarizes an article from LiveScience: There’s a giant asteroid somewhere out in the solar system, and it hurled a big rock at Earth. The evidence for this mystery space rock comes from a diamond-studded meteor that exploded over Sudan in 2008. NASA had spotted the 9-ton (8,200 kilograms), 13-foot (4 meters) meteor heading toward the planet well…
