February 5, 2021 Zimmerman/Batchelor podcast
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

Bob, sorry if this has been covered in an earlier post, but in all the discussions here and other places about creating underground environments for habitation on the Moon, Mars and other locations, has there been any proof of concept work done on Earth? Or, is assumed the technology is so basic that no proof of concept is needed? Thanks.
@Gary I would think the concept of TBM (Tunnel Boring Machinery) is fairly well advanced today, so you should be able to bring one or two with you. These things leave a concrete-lining, so you need to source the concrete or bring it with you from Earth.
Don’t bring concrete from Earth. That is a complete waste of resources. Develop concrete from local sources on the moon. That is where we need to develop technology. Boring tech is well, boring at this point.

my genius Plan:
Some sort of concrete-esque admixture made with indigenous materials + polymers, so when it sets, it’s airtight.
I was thinking more of the discussions about using lava tubes that exist. Seems to me the issue of sealing up the lava tubes would be a different scenario than drilling passageways in solid ground. You wouldn’t have to drill, but sealing the area off might be more challenging. We have lots of lava tubes on earth. I’m just wondering if anyone has tried to create a living environment in one of those to prove out the concept.

I’d be interested in studies on how shotcrete (or similar) behaves off-world.
