Universe Today Podcast

In this week's live questions show, we spend a lot of time talking about the Perseverance landing on Mars. What's happening with my content right now, and is anyone watching the Moon for meteorite impacts?

Here's an interview with me on the SciManDan Podcast. We talked about Perseverance, space conspiracy theories, and much more. Check out the podcast at: https://blubrry.com/thescimandanpodcast/

In this week's questions show, I talk about why some missions go into orbit, and other missions make a direct landing on Mars. Is it a good idea for the SpaceX Falcon Heavy to launch components for the Lunar Gateway? And how can we know if the Universe is finite or infinite?

In this week's questions show, I explain why there are separate challenges for finding life in both the Solar System and in the Milky Way. Can we use water as a propulsion system in space? Will there be interferometer telescopes launched into space?

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.

In this week's live QA, I answer questions about the source of the Earth's water, what happened to Theia after it collided with the Earth? And can we hope for alien artificial intelligence to be peaceful?

My guest this week is the science journalist Elizabeth Howell.

Dr. Howell is one of the most prolific space journalists working in the field, contributing thousands of articles across almost every space news site (including Universe Today). She has also written and collaborated on several books.

Her latest book is called "Canadarm and Collaboration", and it's all about Canada's role in spaceflight.
