The Moon’s Surface Has Enough Oxygen to Sustain 8 Billion People for 100,000 Years there is actually plenty of oxygen on the moon. It just isn’t in a gaseous form. Instead it’s trapped inside regolith—the layer of rock and fine dust that covers the moon’s surface. ........ the moon is mostly made of the same rocks you’ll find on Earth (although with a slightly greater amount of material that came from meteors). ....... Earth’s soil is imbued with remarkable physical, chemical, and biological characteristics. Meanwhile, the materials on the moon’s surface are basically regolith in its original, untouched form. ....... The moon’s regolith is made up of approximately 45 percent oxygen. But that oxygen is tightly bound into the minerals mentioned above. In order to break apart those strong bonds, we need to put in energy. ........ Extracting oxygen from regolith would also require substantial industrial equipment. We’d need to first convert solid metal oxide into liquid form, either by applying heat, or heat combined with solvents or electrolytes. We have the technology to do this on Earth, but moving this apparatus to the Moon—and generating enough energy to run it—will be a mighty challenge. ........ Each cubic meter of lunar regolith contains 1.4 tons of minerals on average, including about 630 kilograms of oxygen. NASA says humans need to breathe about 800 grams of oxygen a day to survive. So 630 kilograms of oxygen would keep a person alive for about two years (or just over). .........

we do have it pretty good here on Earth. And we should do everything we can to protect the blue planet—and its soil in particular—which continues to support all terrestrial life without us even trying.



Beeple’s New NFT Just Sold for $29 Million, and He’ll Update It for the Rest of His Life Just a few months ago, most of us had never heard of an NFT. ........ in the third quarter of this year, trading volume of NFTs hit $10.67 billion, a more than 700-percent increase from the second quarter. Last month, both Coinbase and Sotheby’s announced plans to launch NFT marketplaces. .......... NFT stands for non-fungible token, and it’s a digital certificate that represents ownership of a digital asset. ........ The certificates are one-of-a-kind (that’s the non-fungible part), are verified by and stored on a blockchain, and allow digital assets to be transferred or sold. ........ NFTs are the future of collectible art. ....... Though Human One was doubtless an expensive and highly complex project, it’s likely just the beginning of a whole new type of “living art,” and we’ll see many imitators create their own dynamic 3D NFTs in the near future.
