Flowing water? Rubbish. More like sublimating ice. Water needs pressure to stay liquid.
Im on book 2 of the Delta-V series centered around this asteroid, definitely worth a read or listen if you enjoy hard sci-fi.
The headline is just false as written. The article’s actual claim is that the Ryugu parent body briefly had liquified water in its interior due to an impact a billion years after its accretion. This has interesting implications, because although Ryugu is excessively dry, if the parent body retained water for a billion years, then these kinds of objects could transport water to planetary bodies.
