Robots Might Jump Around to Explore the Moon

How great are wheels, really? Wheels need axles. Suspension. Power of some kind. And roads, or at least swaths of relatively flat and stable terrain. Then you need to maintain all of it. Because of their cost many civilizations across human history, who knew all about wheels and axles, didn’t bother using them for transportation. Another way to look at it – much of human technology mimics nature. Of the simple machines, levers, inclined planes, wedges, and even screws are observed in nature. Why not the wheel?

The Moon’s Poles Have “Wandered” Over Billions of Years

Until 1959, humans had only seen one side of the Moon. The Moon is tidally locked with Earth, and so we can only see one side from the Earth’s surface. It took the soviet Luna 3 spacecraft to capture a blurry image for humans to get their first glimpse of the lunar far side. Because of this, many people imagine that the Moon has always been this way. But as a recent study shows, that isn’t quite true.

NASA Chooses a Supplier to Build its Moonwalking Spacesuits

NASA announced they have chosen Axiom Space to build the spacesuits for the next astronauts to walk on the Moon. The spacesuits will be used on the Artemis III mission, which is planned to land the first woman and the first person of color on the lunar surface.

Axiom Space says the new spacesuits will provide astronauts with advanced capabilities for space exploration while providing NASA commercially developed human systems needed to access, live, and work in microgravity as well as on and around the Moon.

Bouncy Castles on the Moon. Inflated Habitats Might be the Best Way to Get Started on a Lunar Base

In this decade, multiple space agencies will send astronauts to the Moon for the first time since the Apollo Era. In addition to NASA, the ESA, China, and Roscosmos, commercial space entities like SpaceX and Blue Origin are hoping to conduct regular missions in support of human exploration while also mounting their own private ventures. In time, this activity could result in the creation of permanent infrastructure, a regular human presence, and the emergence of a lunar economy. Nevertheless, there are many questions about how humans will live in lunar conditions and what type of facilities will be needed.

To this end, the Austrian-based inflatable structures specialist Pneumocell recently conducted a study to determine if lightweight prefabricated structures would be a suitable option. According to this study, a series of donut-shaped inflatable structures could be transported to the Moon at a low cost, where they would then be inflated. The habitats would be partially buried beneath the lunar regolith and surrounded by solar mirrors that could direct sunlight into their greenhouses. This “Inflatable Moon Habitat” offers a cost-effective and highly self-sufficient means of establishing a foothold on the Moon.

Using “C-Shaped Wheels,” This Rover can Climb Over More Challenging Lunar Terrain

Student teams are an underappreciated resource in much of the scientific community. Joining a team working toward a goal while at university, whether for racing solar-powered cars or digging fish ponds in Africa, is an excellent way to sharpen technical and project skills while improving communication and teamwork. The space industry is starting to catch on to these strengths, with student teams developing exciting projects all over the world. A recent entry comes from students at the Delft University of Technology in the Netherlands – a six-legged robot called Lunar Zebro with a unique take on wheels.

Here is Where Astronauts Might Land on the Moon

In just four days, the inaugural mission of the Artemis Program will lift off from Kennedy Space Center in Florida! Dubbed Artemis I, this mission will see the Space Launch System (SLS) and Orion spacecraft achieve flight together for the first time. The mission will last between 39 and 42 days and consist of the uncrewed Orion flying beyond the Moon, farther than any spaceship has ever traveled, and then looping back around the Moon to return home. This flight, and the crewed Artemis II that will follow, are essentially the dress rehearsal for the long-awaited return to the Moon.

Designated Artemis III, this mission is scheduled to take place in 2025 and will see the “first woman and first person of color” set foot on the lunar surface. It will also be the first time in over 50 years (since Apollo 17 landed in 1972) that astronauts will venture beyond Low Earth Orbit (LEO). In preparation for this, NASA has identified 13 candidate regions in the Moon’s South Pole-Aitken Basin, which they recently shared with the public. Each region contains multiple potential sites where the Starship Human Landing System (HLS) will land.

Artemis Astronauts Could Rely on Solar Cells Made out of Moon Dust

Within the next decade, several space agencies and commercial space partners will send crewed missions to the Moon. Unlike the “footprints and flags” missions of the Apollo Era, these missions are aimed at creating a “sustained program of lunar exploration.” In other words, we’re going back to the Moon with the intent to stay, which means that infrastructure needs to be created. This includes spacecraft, landers, habitats, landing and launch pads, transportation, food, water, and power systems. As always, space agencies are looking for ways to leverage local resources to meet these needs.

This process is known as in-situ resource utilization (ISRU), which reduces costs by limiting the number of payloads that need to be launched from Earth. Thanks to new research by a team from the Tallinn University of Technology (TalTech) in Estonia, it may be possible for astronauts to produce solar cells using locally-sources regolith (moon dust) to create a promising material known as pyrite. These findings could be a game-changer for missions in the near future, which include the ESA’s Moon Village, NASA’s Artemis Program, and the Sino-Russian International Lunar Research Station (ILRS).

South Korea’s First Orbital Mission to the Moon is on its Way

South Korea launched its first robotic mission to the Moon last week, as a SpaceX Falcon 9 successfully launched the Danuri Lunar Pathfinder mission on August 4, 2022 from Florida’s Cape Canaveral Space Force Station.

The spacecraft was placed into a fuel-saving lunar transfer orbit, and it should arrive in lunar orbit in December.

Translated, Danuri means “enjoy the Moon.”

Lava Tubes on the Moon Maintain Comfortable Room Temperatures Inside

Searching for a comfortable place to set up a research station on the Moon? Look no further than the interior parts of lunar pits and caves. While lack of air will be an issue, new research indicates these underground sanctuaries have steady temperatures that hover around 17 Celsius, or 63 Fahrenheit, even though the Moon’s surface heats up to about 127 C (260 F) during the day and cool to minus 173 C (minus 280 F) at night.

Engineers are Testing how VIPER can Handle the Gnarliest Lunar Terrain

NASA’s getting ready to send a VIPER to the Moon. Not the popular sports car but a rugged vehicle that can handle whatever the lunar surface can throw at it. The Volatiles Investigating Polar Exploration Rover (VIPER) was put through its paces recently at the Glenn Research Center in Cleveland. The prototype drove up test slopes and clambered over boulders and craters. It also made its way through a simulated quicksand type of soil in a “sink tank”. It passed with flying colors, and showed engineers how it will handle similar conditions on the Moon.
