How Could Astronauts Call for Help from the Moon?

Exploring the Moon poses significant risks, with its extreme environment and hazardous terrain presenting numerous challenges. In the event of a major accident, assistance might take days or even weeks to arrive. To address this, Australian researchers have created a distress alert system based upon the COSPAS-SARSAT technology used for Earth-based search and rescue operations. It relies on low-power emergency beacons that astronauts could activate with minimal setup and use a planned lunar satellite network for communication and rescue coordination.

Launching Mass From the Moon Helped by Lunar Gravity Anomalies

Placing a mass driver on the Moon has long been a dream of space exploration enthusiasts. It would open up so many possibilities for the exploration of our solar system and the possibility of actually living in space. Gerard O’Neill, in his work on the gigantic cylinders that now bear his name, mentioned using a lunar mass driver as the source of the material to build them. So far, we have yet to see such an engineering wonder in the real world, but as more research is done on the topic, more and more feasible paths seem to be opening up to its potential implementation.

NASA Wants to Move Heavy Cargo on the Moon

While new rockets and human missions to the Moon are in the press, NASA is quietly thinking through the nuts and bolts of a long-term presence on the Moon. They have already released two white papers about the lunar logistics they’ll require in the future and are now requesting proposals from companies to supply some serious cargo transportation. But this isn’t just for space transport; NASA is also looking for ground transportation on the Moon that can move cargo weighing as much as 2,000 to 6,000 kg (4,400 to 13,000 pounds.)

Scientists Determine the Age of the Moon’s Oldest and Largest Impact Basin

The massive South Pole-Aitken (SPA) basin is one of the Moon’s dominant features, though it’s not visible from Earth. It’s on the lunar far side, and only visible to spacecraft. It’s one of the largest impact features in the Solar System, and there are many outstanding questions about it. What type of impactor created it? Where did the ejected material end up? Is it feasible or worthwhile to explore it?

But the biggest question could be: how old is it?

New Simulation Will Help Future Missions Collect Moon Dust

In this decade and the next, multiple space agencies will send crewed missions to the Moon for the first time since the Apollo Era. These missions will culminate in the creation of permanent lunar infrastructure, including habitats, using local resources – aka. In-situ resource utilization (ISRU). This will include lunar regolith, which robots equipped with additive manufacturing (3D printing) will use to fashion building materials. These operations will leverage advances in teleoperation, where controllers on Earth will remotely operate robots on the lunar surface.

According to new research by scientists at the University of Bristol, the technology is one step closer to realization. Through a virtual simulation, the team completed a sample collection task and sent commands to a robot that mimicked the simulation’s actions in real life. Meanwhile, the team monitored the simulation without requiring live camera streams, which are subject to a communications lag on the Moon. This project effectively demonstrates that the team’s method is well-suited for teleoperations on the lunar surface.

China Releases its First Roadmap for Space Science and Exploration Through 2050.

China’s space program has advanced considerably since the turn of the century. In addition to developing heavy-launch vehicles like the Long March 5 and building a modular space station in orbit, China has also embarked on an ambitious program of lunar exploration (Chang’e) – which has launched six robotic missions to explore the Moon’s surface since 2007. These missions are paving the way for crewed missions to the Moon by 2030 and creating a permanent habitat around the Moon’s southern polar region – the International Lunar Research Station (ILRS).

They also plan to send crewed missions to Mars by 2033, which will culminate in the creation of a permanent base there too. Earlier today, the Chinese Academy of Sciences (CAS), the China National Space Administration (CNSA), and the China Manned Space Agency (CMSE) jointly released the country’s first long-term scheme for space science and exploration. Titled “National Medium—and Long-Term Development Plan for Space Science (2024-2050),” this plan elaborated on the basic principles, development goals, and roadmap for the country’s space science and exploration through 2050.

Was the Moon Captured?

The general consensus is that Theia crashed into Earth billions of years ago and led to the formation of the Moon. The story doesn’t end there though since there are a few lines of evidence to suggest the Moon could have been captured by the gravitational pull of the Earth instead. The orbit of the Moon is one such observation that leads to a different conclusion for it’s in-line with the plane of the ecliptic rather than the Earth’s equator. A team of researchers have suggested capture theory was the Moon’s origin.

Unloading Cargo on the Moon

I don’t think it’s something I have ever really thought of! Robotic explorers can travel around the Solar System visiting our neighbouring planets but when they arrive, sometimes a scientific package must be deployed to the surface. Never occurred to me just how that’s achieved! With a number of landers scheduled to visit the Moon, NASA are testing a new robotic arm called the Lightweight Surface Manipulation System AutoNomy capabilities Development for Surface Operations or LANDO for short! It will lift payloads off the lander and pop them down gently on the surface of the Moon.

Where do you go to practice living and working on the Moon before you actually get there? That’s the question the European Space Agency and German Aerospace Center wanted to answer. So, they worked together to build a mockup of the Moon’s surface near Cologne, Germany.

A New Rover Design Could Crawl Across the Moon for Decades Harvesting Water

A view of the ice-mining Lunar rover and its main components.

We have known that water ice exists on the Moon since 1998. These large deposits are found in the permanently shadowed craters around the polar region. The challenge is how to get it since shadowed craters are not the best place for solar powered vehicles to operate. A team of engineers have identified a design for an ice-mining vehicle powered by americium-241. With a half-life of 432 years, this element is an ideal power source for a vehicle to operate in the dark for several decades.
