China's Lunar Samples Contain Graphene Flakes

In 2004, scientists at the University of Manchester first isolated and investigated graphene, the supermaterial composed of single-layer carbon atoms arranged in a hexagonal honeycomb lattice. Since then, it has become a wonder, with properties that make it extremely useful in numerous applications. Among scientists, it is generally believed that about 1.9% of carbon in the interstellar medium (ISM) exists in the form of graphene, with its shape and structure determined by the process of its formation.

As it happens, there could be lots of this supermaterial on the surface of the Moon. In a recent study, researchers from the Chinese Academy of Science (CAS) revealed naturally formed graphene arranged in a special thin-layered structure on the Moon. These findings could have drastic implications for our understanding of how the Moon formed and lead to new methods for the manufacture of graphene, with applications ranging from electronics, power storage, construction, and supermaterials. They could also prove useful for future missions that will create permanent infrastructure on the lunar surface.

Scientists Want to Use the Moon to Safeguard Earth’s Biodiversity

There’s something wrong with us.

We’ve risen to prominence on a world that’s positively “rippling with life,” as Carl Sagan described it. The more we study our planet, the more we find life eking out an existence in the most unlikely of places.

Yet we seem destined to drive many species to extinction, even though we see those extinctions coming from miles away.

As an indication of how serious the problem is, one group of researchers suggests we use the Moon—yes, the Moon—as a safe repository for Earth’s biodiversity.

When Earth Danced with Polar Moons

The origins of the Moon have been the cause of many a scientific debate over the years but more recently we seem to have settled on a consensus. That a Mars-sized object crashed into Earth billions of years ago, with the debris coalescing into the Moon. The newly formed Moon drifted slowly away from Earth over the following eons but a new study suggests some surprising nuances to the accepted model.

How will future robotic explorers navigate the difficult subterranean environments of caves and lava tubes on the Moon and Mars? This is what a recent study published in Science Robotics hopes to address as a team of researchers from Stanford University investigated the use of a novel robotic explorer called ReachBot, which could potentially use its unique mechanical design to explore deep caves and lava tubes on the Moon and Mars in the future.

The Entrance of a Lunar Lava Tube Mapped from Space

Craters are a familiar sight on the lunar surface and indeed on many of the rocky planets in the Solar System. There are other circular features that are picked up on images from orbiters but these pits are thought to be the collapsed roofs of lava tubes. A team of researchers have mapped one of these tubes using radar reflection and created the first 3D map of the tube’s entrance. Places like these could make ideal places to setup research stations, protected from the harsh environment of an alien world.

Moon Dust Could Contaminate Lunar Explorers’ Water Supply

Water purification is a big business on Earth. Companies offer everything from desalination to providing just the right pH level for drinking water. But on the Moon, there won’t be a similar technical infrastructure to support the astronauts attempting to make a permanent base there. And there’s one particular material that will make water purification even harder – Moon dust.

NASA Stops Work on VIPER Moon Rover, Citing Cost and Schedule Issues

NASA says it intends to discontinue development of its VIPER moon rover, due to cost increases and schedule delays — but the agency is also pointing to other opportunities for robotic exploration of the lunar south polar region.

A Moon Base Will Need a Transport System

Through the Artemis Program, NASA will return astronauts to the lunar surface for the first time since Apollo 17 landed in 1972. Beyond this historic mission, scheduled for September 2026, NASA plans to establish the infrastructure that will enable annual missions to the Moon, eventually leading to a permanent human presence there. As we addressed in a previous article, this will lead to a huge demand for cargo delivery systems that meet the logistical, scientific, and technical requirements of crews engaged in exploration.

Beyond this capacity for delivering crews and cargo, there is also the need for transportation systems that will address logistical needs and assist in exploration efforts. These requirements were outlined in a 2024 Moon to Mars Architecture white paper titled “Lunar Mobility Drivers and Needs.” Picking up from the concurrently-released “Lunar Surface Cargo,” this whitepaper addresses the need for lunar infrastructure that will enable the movement of astronauts and payloads from landing sites to where they are needed the most. As usual, they identified a critical gap between the current capabilities and what is to be expected.

NASA's Skyrocketing Need for Cargo Deliveries to the Moon

NASA has big plans for the Moon. Through the Artemis Program, NASA plans to create a program of “sustained exploration and lunar development.” This will include the creation of the Lunar Gateway, an orbital habitat that will facilitate missions to and from the surface, and the Artemis Base Camp that will allow for extended stays. Through its Commercial Lunar Payload Services (CLPS) program, NASA has contracted with commercial partners like SpaceX and Blue Origin to deliver scientific experiments and crew to the lunar surface.

However, these efforts are expected to culminate in the creation of a permanent outpost and human presence on the Moon. This will require far more in the way of crew and payload services to ensure crews can be sustained in the long run. In a recent white paper, “Lunar Surface Cargo,” NASA researchers identified a significant gap between current cargo delivery capabilities and future demand. The paper indicates that this growing cargo demand can only be met by creating a “mixed cargo lander fleet.”

LEGO Bricks Printed out of Space Dust

There have been many proposals for building structures on the Moon out of lunar regolith. But here’s an idea sure to resonate with creators, mechanical tinkerers, model builders and the kid inside us all.

What about using actual LEGO bricks?

Researchers ground up a 4.5-billion-year-old meteorite and used the dust to 3D print LEGO-style space bricks. They actually click together like the plastic variety, with so far only one downside: they only come in one color, grey.

Want to see some of these lunar LEGOs? LEGO will showcase the space bricks at some of its stores.
