Walkabout the Galaxy

NASA unveils a new accelerated timeline to get astronauts forward (not back, get it?) to the Moon in 2024 with the new Artemis program. The astroquarks bring you up to speed on the latest space exploration news, and are joined by author Dennis Taylor of the "Bobiverse" trilogy of science fiction novels ("We are Legion", "For We Are Many", and "All These Worlds"). This gets us into Von Neumann machines, the Fermi paradox and the Great Filter, and bonus Bob trivia.

The astroquarks discuss news about lunar quakes and Venus... volcanoes. But volcanoes doesn't rhyme with quakes, so I sacrificed alliteration for rhyming. Venus may be volcanically active, at least on relatively recent geological timescales. If only we could go back in time to see! Top quark Jim Cooney will bring us up to date on a new experiment that fiddles with the direction of time's arrow. All that, plus space news and bonus trivia on this episode of Walkabout.

From a human-made crater (well, spacecraft-made) on an asteroid, to the Moon-forming impact, to an accelerating pace of black hole merger detections, the astroquarks survey the latest news in astronomical collisions. The asteroid Apophis has a close date with Earth in 2029, and what episode of Walkabout would be complete without some general relativistic frame dragging? Zoe Landsman joins us while Charm quark Addie Dove is off launching things into space! Plus space news and a historical/avengical trivia.
