An ambitious Japanese mission, Hayabusa-2 has arrived at its target asteroid Ryugu. Are-you-good with that? See what we did there? (Ryugu'd? Get it?) Yes, that's the level of discourse on Walkabout the Galaxy, but we also find out about the great science to come from this exciting asteroid sample return mission, and a look ahead to the James Webb Space Telescope, whose launch has been slipped to make absolutely sure that nothing got Ryugu'd while building it. Plus we talk about the science of learning, and un-learning, with our special guest Anna Turner.\\xa0
