Universe Today Podcast

This week I interview Chris Prophet, the author of "SpaceX from the Ground Up". His book, now in its 6th edition covers the story of SpaceX, from its initial concept to the latest Starship tests.

In this week's Q&A show, I answer questions about Starship might be able to provide artificial gravity, whether I'd prefer to have LUVOIR or the Overwhelmingly Large Telescope, and if nuclear-powered rockets will work in space.

In this week's QA, I talk about what's driving the expansion of the Universe, how big the observable Universe is to the actual Universe, and what will happen to dogs in gravity.

In this week's interview, I talk to David Brown about his new book: The Mission. It's all about the campaign to design and build the Europa Clipper mission and everything that happened behind-the-scenes.

Contributing author Matthew Cimone decided to record an audio narration for his article this week on Universe Today. I thought it was a cool idea, so I included it here on the podcast feed. Let me know if you enjoyed it and want to hear more of them.

In this week's interview, I talk with Devin Carroll, a robotics Ph.D. student at the modular robotics lab at the University of Pennsylvania. Devin is working on robots that can build their own structure out of ice.

In this week's live Q&A, I talk about the new Space Launch System hot-fire test, how Breakthrough Starshot spacecraft might be able to communicate with home, and what messages would we send to aliens that we might never be able to reach physically.

Welcome to the new style Q&As, which we're now recording every Monday live on my YouTube channel at 5pm Pacific Time. This week we got a lot of great questions about the Proxima Centauri signal, the Fermi Paradox, and Breakthrough Starshot.

In this week's interview, I talk with Chris Carr, one of the co-hosts in the Weekly Space Hangout. Chris is a grad student at Columbia University, specializing in the cosmos inside and outside the Milky Way.

In this week's last QA of 2020, I go long answering questions about space and astronomy. I talk about the news of a radio signal received from Proxima Centauri, an update on my attempts to learn Mandarin Chinese, and a long diatribe about megaconstellations and their impact on astronomy.
