China’s Rover Finds That Regolith on the Moon’s far-Side is Stickier Than the Near-Side

We’re never able to see the far side of the moon from the Earth, but that doesn’t mean it’s that different. Recently rovers and satellites have started exploring the lesser-known side of the moon. They found a slightly different geology than that discovered on the near side, which might have implications for navigating the far side in the future.

13 Rovers Recently Competed to Scour the (Simulated) Moon to Harvest Resources

Challenges are one way to encourage innovation. They’ve been leveraged by numerous space and non-space research organizations in the last decade, with varying degrees of success. The European Space Agency (ESA) is now getting in on the action, with a challenge to prospect the moon for vital resources that will make a sustainable presence there possible. Recently thirteen teams from all over the continent (and Canada) competed in a gloomy hall in the Erasmus Innovation Centre in the Netherlands.

The Moon’s Crust was Formed From a Frozen Slushy Magma

Scientists’ detailed study of the Moon dates back to the Apollo missions when astronauts brought rock samples from the lunar surface back to Earth for analysis. Apollo 11 gathered samples from the lunar highland regions, the pale areas on the Moon’s surface easily seen from Earth. The highlands are made of a relatively light rock called anorthosite, which formed early in the history of the Moon, between 4.3 and 4.5 billion years ago.

There’s some mystery involved in the anorthosite formation on the Moon. The age of the anorthosite highlands doesn’t match how long it took for the Moon’s magma ocean to cool. But scientists behind a new study think they’ve solved that mystery.

China’s Lander Has Detected Water on the Moon

China’s Chang’e-5 lunar lander has found evidence of hydroxyl (OH) on the Moon. Hydroxyl is a close chemical cousin of water, H2O. While several other orbital missions have detected OH on the Moon previously, Chang’e-5 marks the first time it has been detected by a spacecraft sitting on the lunar surface.

The Surface of the Moon is Electrically Charged, Which Could Allow a Hovering Robot to Explore it

Let’s not sugarcoat it. Exploring the Moon is not for the faint of heart! It’s an airless body, which means there is no atmosphere, the surface temperatures are extreme, and there’s lots of radiation. The low gravity also means you can never really walk on the surface and have to bounce around in a bulky spacesuit until you fall over. And you can bet your bottom dollar people will make a supercut of the footage someday (see below). Then there’s that awful moondust (aka. lunar regolith), which is electrostatically charged and sticks to EVERYTHING!

Looking to take advantage of this, researchers from the Massachusetts Institute of Technology (MIT) began testing a new concept for a hovering rover that harnesses the Moon’s natural charge to levitate across the surface. On the Moon, this surface charge is strong enough to levitate moon dust more than 1 meter (3.3 ft) above the surface. With support from NASA, this research could lead to a new type of robotic exploration vehicle that will help astronauts explore the Moon in the coming years.

China’s Rover Checks out that Weird Cube on the Moon. Surprise! It’s a Rock.

Back in early December 2021, China’s Yutu 2 rover made headlines when it spied what looked like a curious cube-shaped object on the Moon’s surface. Of course, speculations ran rampant. And it didn’t help matters any when the China National Space Administration (CNSA) nicknamed the object the “mystery hut.”

An update today from Yutu’s cameras reveals the true nature of this object. Yup, it’s just a rock. And not very cube-shaped, either.

The Moon is a Barren and Desolate, but Lunar Caves Could Offer Some Shelter From the Harsh Environment

The dream of building a permanent settlement on the Moon: a place where humans from all walks of life can come together and give rise to a new culture and identity. A place where vital scientific research and experiments can be conducted, lunar industries created, and people can go for a little “adventure tourism.” It’s been the stuff of science fiction and speculative literature for over a century. But in the coming years, it could very well become a reality.

This presents many challenges but also opportunities for creative solutions. For years, astronomers have speculated that the perfect place to create a lunar colony is underground, specifically within pits, caves, and stable lava tubes visible and accessible from the lunar surface. According to new research from CU Boulder, preliminary results show these pits to be remarkably stable compared to conditions on the surface.

Not Just Water, There Could be Frozen Carbon Dioxide on the Moon too

Despite all its wonderful properties, water isn’t the only resource needed for space exploration. Carbon is another important ingredient for many necessary materials, such as steel, rocket fuel, and biomaterials. Therefore, proponents of lunar exploration should be excited by a recent study led by Dr. Norbert Schorghofer of the Planetary Science Institute that found natural “cold traps” for carbon dioxide in some of the permanently shadowed craters of the moon.

Over the next fifteen years, multiple space agencies and their commercial partners intend to mount crewed missions to the Moon and Mars. In addition to placing “footprints and flags” on these celestial bodies, there are plans to establish the infrastructure to allow for a long-term human presence. To meet these mission requirements and ensure astronaut safety, several technologies are currently being researched and developed.

At their core, these technologies are all about achieving self-sufficiency in terms of resources, materials, and energy. To ensure that these missions have all the energy they need to conduct operations, NASA is developing a Fission Surface Power (FSP) system that will provide a safe, efficient, and reliable electricity supply. In conjunction with solar cells, batteries, and fuel cells, this technology will allow for long-term missions to the Moon and Mars in the near future.

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!
