There’s Enough Oxygen in the Lunar Regolith to Support Billions of People on the Moon

When it comes to the future of space exploration, a handful of practices are essential for mission planners. Foremost among them is the concept of In-Situ Resource Utilization (ISRU), providing food, water, construction materials, and other vital elements using local resources. And when it comes to missions destined for the Moon and Mars in the coming years, the ability to harvest ice, regolith, and other elements are crucial to mission success.

In preparation for the Artemis missions, NASA planners are focused on finding the optimal way to produce oxygen gas (O₂) from all of the elemental oxygen locked up in the Moon’s surface dust (aka. lunar regolith). In fact, current estimates indicate that there is enough elemental oxygen contained in the top ten meters (33 feet) of lunar regolith to create enough O₂ for every person on Earth for the next 100,000 years – more than enough for a lunar settlement!

Did the Moon Ever Have a Magnetosphere?

In a few years, NASA will be sending astronauts to the Moon for the first time since the Apollo Era (1969-1972). As part of the Artemis Program, the long-term goal is to create the necessary infrastructure for a “sustained program of lunar exploration.” The opportunities this will present for lunar research are profound and will likely result in new discoveries about the formation and evolution of the Moon.

In particular, scientists are hoping to investigate the long-standing mystery of whether or not the Moon had a magnetosphere. In anticipation of what scientists might find, an international team of geophysicists led by the University of Rochester examined samples of lunar material brought back by the Apollo astronauts. Based on the composition of these samples, the team determined that the Moon’s dynamo was short-lived.

Astronauts Could Dust off Themselves and Equipment on the Moon With an Electron Beam

In the coming years, NASA will be sending astronauts to the Moon for the first time since the Apollo Era. This time, and as part of the Artemis Program, NASA also plans to build the necessary infrastructure to establish a sustained human presence on the Moon and eventually missions to Mars – including the Artemis Base Camp and the orbiting Lunar Gateway.

They’ll be getting some new equipment, such as the exploration Extravehicular Mobility Unity (xEMU) spacesuit and a fancy new lunar lander. Of course, as the Artemis astronauts will also have to deal with the same hazards as their predecessors – not the least of which is lunar dust (or regolith). Luckily, NASA is investigating a possible solution in the form of a handheld electron/ultraviolet (UV) device that could mitigate this hazard.

Lunar Dust is Still One of The Biggest Challenges Facing Moon Exploration

In the coming years, astronauts will be returning to the Moon for the first time since the closing of the Apollo Era. Beyond that, NASA and other space agencies plan to establish the necessary infrastructure to maintain a human presence there. This will include the Artemis Gateway in orbit (formerly the Lunar Gateway) and bases on the surface, like NASA’s Artemis Base Camp and the ESA’s International Moon Village.

This presents a number of challenges. The Moon is an airless body, it experiences extreme variations in temperature, and its surface is exposed to far more radiation than we experience here on Earth. On top of that, there’s the lunar dust (aka. regolith), a fine powder that sticks to everything. To address this particular problem, a team of ESA-led researchers is developing materials that will provide better protection for lunar explorers.

NASA Will Pay You to Retrieve Regolith and Rocks from the Moon

As part of Project Artemis, NASA intends to send the first woman and the next man to the Moon by 2024, in what will be the first crewed mission to the lunar since the Apollo Era. By the end of the decade, NASA also hopes to have all the infrastructure in place to create a program for “sustainable lunar exploration,” which will include the Lunar Gateway (a habitat in orbit) and the Artemis Base Camp (a habitat on the surface).

Part of this commitment entails the recovery and use of resources that are harvested locally, including regolith to create building materials and ice to create everything from drinking water to rocket fuel. To this end, NASA has asked its commercial partners to collect samples of lunar soil or rocks as part of a proof-of-concept demonstration of how they will scout and harvest natural resources and conduct commercial operations on the Moon.

For many of us, gardening has been a therapeutic distraction during this time of pandemic quarantine. But some researchers from the Jet Propulsion Lab have been gardening at home with a specific goal in mind: growing food on the Moon.

NASA is Testing a Coating to Help Astronauts and Their Equipment Shed Dangerous Lunar Dust

In the coming years, NASA is going back to the Moon for the first time since the Apollo Era. Rather than being a “footprints and flags” operation, Project Artemis is intended to be the first step in creating a sustainable human presence on the Moon. Naturally, this presents a number of challenges, not the least of which has to do with lunar regolith (aka. moondust). For this reason, NASA is investigating strategies for mitigating this threat.

This is What Moondust Looks Like When You Remove All the Oxygen. A Pile of Metal

Both the oxygen and metal could be used in future by settlers on the Moon. Image Credit: Beth Lomax - University of Glasgow

The Moon has abundant oxygen and minerals, things that are indispensable to any space-faring civilization. The problem is they’re locked up together in the regolith. Separating the two will provide a wealth of critical resources, but separating them is a knotty problem.

How Do We Settle on the Moon?

Welcome back to our series on Settling the Solar System! Today, we take a look at the closest celestial neighbor to Earth. That’s right, we’re taking a look at the Moon!

Chances are, we’ve all heard about it more than once in our lifetimes and even have some thoughts of our own on the subject. But for space agencies around the world, futurists, and private aerospace companies, the idea of colonizing the Moon is not a question of “if”, but “when” and “how”. For some, establishing a permanent human presence on the Moon is a matter of destiny while for others, it’s a matter of survival.

Not surprisingly, plans for establishing a human settlement predate both the Moon Landing and the Space Race. In the past few decades, many of these plansa have been dusted off and updated thanks to plans for a renewed era of lunar exploration. So what would it take to establish a permanent human presence on the Moon, when could it happen, and are we up to that challenge?

The Moon is not just Earth’s closest celestial neighbor. It’s also a natural waypoint for any mission that will be going to Mars or beyond in the coming years. It’s little wonder then why space agencies like NASA, Roscosmos, the ESA and China are hoping to send crewed missions there in the near future and construct bases that could be used to resupply and refuel missions headed to deep space.

So far, all the proposals made for a lunar base have centered on in-situ resource utilization (ISRU) and 3D printing – where robots will manufacture the base out of lunar regolith. For this purpose, the Laser Zentrum Hannover (LZH) and the Institute of Space Systems (IRAS) at the Technical University of Braunschweig came together to develop a laser system capable of turning moon dust into building materials.
