My February birthday fund-raising campaign for Behind the Black is now over. Thank you to everyone that so generously donated. You don’t have to give anything to read my work, and yet so many of you donate or subscribe. I can’t express what that support means to me.

 

For those who still wish to support my work, please consider donating or subscribing to Behind the Black, either by giving a one-time contribution or a regular subscription. There are five ways of doing so:

 

1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get.

 

2. Patreon: Go to my website there and pick one of five monthly subscription amounts, or by making a one-time donation. Takes about a 10% cut.

 

3. A Paypal Donation or subscription, which takes about a 15% cut:

 

4. Donate by check. I get whatever you donate. Make the check payable to Robert Zimmerman and mail it to

South Korean researchers turn simulated lunar soil into building blocks

Using simulated lunar soil, South Korean researchers have developed the engineering that turns that soil into building blocks shaped as needed.

The researchers first produce simulated moon soil by grinding black volcanic rock from Cheorwon County bordering the North. They then use a microwave to turn the sand-like simulant into solidified blocks. Lee said the team has developed a technique to make blocks by heating the soil in a mold to more than 1,000 degrees Celsius in two to three hours and cooling them. In space, the process could be powered by nuclear energy.

The article at the link also provides a nice summary of the status of South Korea’s entire space effort.

Genesis cover

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 print edition can be purchased at Amazon or from any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. 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

    These blocks are for compression; I expect them to, er, explode if filled with 1 bar from the inside.
    I assume the same technique will work for asteroid regolith, after we spin those rubblepiles around.

    One block at a time is OK. But not for any large construction project.
    If you scale it up and make larger blocks will they get even heat or will the corners be colder and not as hard.

    I would like a sprayable cement make from rigolith.
    Make a cement foundation then inflate a dome on top of it. Spray the cement onto the outside then deflate the done and pull it out of the door. Use it over and over again to create a whole village of domes.

    Ir send up a dome and spray the cement on the inside to make it rigid. Any water used in making the cement could be recovered by dehumidifying from the inside until the cement is dry.
