August 02, 2024TWiS 122: No City on Mars? - A Debate on Human Expansion and the Popular New Book, 'A City on Mars'
It's been said that Mars ain't the kind of place to raise your kids, and that's certainly the assertion of the popular 2023 book, "A City on Mars" by Kelly and Zack Weinersmith. In fact, they question the future of settling humans off Earth in its entirety. Certainly, it will be challenging, but is it impossible? Are there reasons we should not go? We gathered together two of our favorite experts on the topic, Dale Skran, the COO and SVP of the National Space Society, and Mr. YouTube himself, Isaac Arthur—who has produced maybe 100 hours or more of well-regarded videos on the subject—to discuss the book and our prospects for rational, realistic space settlement plans. Join us!
"A City on Mars" takes a skeptical and humorous look at space settlement, questioning our readiness for having children in space, building space farms, and creating independent space nations.

Dale Skran wrote a comprehensive 40,000-word review of the book, acknowledging its depth while disagreeing with many of its conclusions. He believes the book represents the current stage of opposition to the increasingly realistic prospect of space settlement.

The hosts discuss the potential benefits and resources available in space, with Dale and Isaac emphasizing the vast opportunities and the need for reasonable regulation to facilitate space development.

The challenges of human reproduction in space are examined, with the hosts agreeing on the importance of further research and the need for artificial gravity experiments on space stations.

The potential for conflict and war in space is explored, with Dale arguing that space settlements will likely be more resilient and less vulnerable than Earth-based cities due to their designed defenses against natural and artificial threats.

The hosts critique the book's pessimistic view of space settlement and its suggestion to wait centuries until humanity has solved all its problems before venturing into space. They argue that space development and solving Earth's issues can and should happen concurrently.

Dale Skran highlights an interesting idea from the book: the possibility of a dual life cycle for settlers, with reproduction occurring in 1G spin gravity settlements while adults spend much of their time working in low-gravity environments like the Moon or Mars.

July 26, 2024TWiS 121: An Exploding Star Near You! - A Nova is Coming with Carlos Badenes
A nova is a star that periodically sheds mass in a huge flare-up of light and energy. This week, astrophysicist Dr. Carlos Badenes from the University of Pittsburgh joins us to discuss a star that should be going nova in the next few weeks--and will be visible in the night sky for about 6-7 days! T Corona Borealis (TCrB) is a binary system comprising two stars in the constellation Corona Borealis that bursts into magnitude 2 (as seen from Earth) about every 80 years--and should do so again by mid-September! Join us.
Headlines:
NASA's Perseverance rover discovers a rock on Mars that shows intriguing signs of potential ancient microbial life, sparking excitement among scientists

Starliner Update: NASA and Boeing discuss the extended mission of the Starliner spacecraft, addressing concerns and highlighting the crew's safety and productivity

Scientists uncover evidence suggesting Mercury's crust harbors a 10-mile thick diamond layer, formed by unique planetary processes
Main Topic - The Visible Nova in the Sky Near You:
T Coronae Borealis, a recurring nova located in the constellation Corona Borealis, is expected to become visible to the naked eye between now and September 2024

Novae are binary star systems where a white dwarf accumulates material from its companion star, leading to a thermonuclear runaway and a bright outburst

Supernovae, in contrast, are the explosive deaths of stars, either through the complete disruption of a white dwarf or the collapse of a massive star's core

Historical accounts of "new stars" include Tycho's Supernova (1572), Kepler's Supernova (1604), and the Crab Nebula progenitor (1054)

Dr. Badenes discusses his research on novae in nearby galaxies and the use of the Hubble Space Telescope to study the progenitors of thermonuclear supernovae

The crew explores the limits of recurring novae, the possibility of a white dwarf exploding as a Type Ia supernova, and the anticipated supernova of the star Betelgeuse in the constellation Orion
