Glass beads boost hopes for using the moon’s water

Beads of glass could become a key source of water for future crewed settlements on the moon, researchers say.

That claim is based on an assessment of the water contained within a sampling of glassy beads that were created over the course of millennia by cosmic impacts on the moon, and ended up being brought back to Earth in 2020 by China’s Chang’e-5 sample return mission.

A spectroscopic analysis determined that the beads contained more water than the researchers expected based on past studies. They surmised that interactions between hydrogen ions in the solar wind and oxygen-bearing materials in lunar soil created H2O molecules that could be trapped within the glass — and then diffused under the right conditions.

Based on an extrapolation of such findings, the research team — headed by scientists from the Chinese Academy of Sciences — estimates that glass beads in lunar soil may contain up to 270 trillion kilograms (595 trillion pounds, or 71 trillion gallons) of water.

“We propose that impact glass beads in lunar soils are a prime water reservoir candidate able to drive the lunar surface water cycle,” the researchers report in Nature Geoscience.

Get a way-out reality check on dreams of leaving Earth

Amazon founder Jeff Bezos wants to have millions of people living and working in space — that’s why he founded his Blue Origin space venture more than two decades ago. But what if living in space turns out to be like holing up in an Amazon warehouse?

“The reality of going to another planet in our current environment, I think … the best analogy is an Amazon fulfillment center,” Taylor Genovese, an anthropologist at Arizona State University, says in “Last Exit: Space,” a new documentary about space settlement narrated by famed filmmaker Werner Herzog.

“You won’t be able to actually see where you are,” Genovese explains. “You’re going to be inside of a factory, and you’re not going to experience what you think you’re going to be experiencing — that is, the kind of awe of being on another planet and experiencing being off Earth. No, you’re going to be working inside of a cubicle.”

That’s a perspective you won’t often hear in the wave of space documentaries flowing through streaming-video outlets, including “Countdown” and “Return to Space” on Netflix, and “Secrets of the Universe” on Curiosity Stream.

But Rudolph Herzog — Werner’s son and the director of “Last Exit: Space,” now playing on Discovery+ — wasn’t that interested in doing a conventional documentary about the final frontier.

“I just like the edgy, quirky stories,” the younger Herzog, who’s built up his own portfolio of film projects, explains in the latest episode of the Fiction Science podcast. “I think everybody knows about Elon Musk, and everybody knows what Jeff Bezos is up to. … I just wanted to show the incredible lengths people will go to, to live this dream of going to space.”

Space settlers just might dig a moon of Mars

The smaller of Mars’ two moons, Deimos, was named after the Greek god of terror — but the way former NASA flight surgeon Jim Logan sees it, Deimos could be a comfort zone for space settlers.

“The Mars-facing side of Deimos is probably the most valuable real estate in the solar system,” Logan, co-founder of the Space Enterprise Institute, said today at Seattle’s Museum of Flight.

Logan laid out his case for Deimos during a conference on space settlement, presented this week by the Space Studies Institute to highlight the late Princeton physicist Gerard O’Neill’s vision for humanity’s expansion into the solar system.

Space settlement vision updated after 50 years

Fifty years ago, a Princeton physicist named Gerard O’Neill asked his students to help him come up with a plan for setting up settlements in space.

Just a few years later, O’Neill published the resulting vision for freestanding space colonies as a book titled “The High Frontier” — a book that helped inspire Amazon billionaire Jeff Bezos’ vision of having millions of people living and working in space.

Now the keepers of the “High Frontier” flame at the California-based Space Studies Institute are revisiting O’Neill’s original vision, with an eye toward updating it for the 21st century.

“The fact is, a lot has changed in the last half-century,” Edward Wright, a senior researcher at the Space Studies Institute, said today at the start of a two-day conference presented by the institute at Seattle’s Museum of Flight.
