Ripples on the Cosmic Ocean

Ripples on the Cosmic Ocean

What happens in space doesn’t stay in space. Historian Dagomar Degroot joins Planetary Radio host Sarah Al-Ahmed to explore how shifting solar cycles, volcanic eruptions on Venus, Martian dust storms, and even mistaken sightings of lunar forests have influenced life, science, and society on Earth. His new book, “Ripples on the Cosmic Ocean: An Environmental History of Our Place in the Solar System,” reframes the Solar System as part of our cosmic environment, one that has shaped humanity’s past and will define our future.

Then, Planetary Society Director of Government Relations Jack Kiraly updates us on the latest developments in space policy, including the ongoing search for NASA’s next administrator and proposed changes to the Artemis program’s launch vehicles. And stick around for Bruce Betts, The Planetary Society’s chief scientist, in What’s Up.
