CAPE CANAVERAL, Fla. (AP) — Scientists have confirmed a cave on the moon, not far from where Neil Armstrong and Buzz Aldrin landed 55 years ago, and suspect there are hundreds more that could house future astronauts.

An Italian-led team reported Monday that there’s evidence for a sizable cave accessible from the deepest known pit on the moon. It’s located at the Sea of Tranquility, just 250 miles (400 kilometers) from Apollo 11’s landing site.

The pit, like the more than 200 others discovered up there, was created by the collapse of a lava tube.

Researchers analyzed radar measurements by NASA’s Lunar Reconnaissance Orbiter, and compared the results with lava tubes on Earth. Their findings appeared in the journal Nature Astronomy.

The radar data reveals only the initial part of the underground cavity, according to the scientists. They estimate it’s at least 130 feet (40 meters) wide and tens of yards (meters) long, probably more.      READ MORE...

Russia & China to put Nuclear Plant on Moon


MOSCOW, March 5 (Reuters) - Russia and China are considering putting a nuclear power plant on the moon from 2033-35, Yuri Borisov, the head of Russia's space agency Roscosmos said on Tuesday, something he said could one day allow lunar settlements to be built.

Borisov, a former deputy defence minister, said that Russia and China had been jointly working on a lunar programme and that Moscow was able to contribute with its expertise on "nuclear space energy".

"Today we are seriously considering a project - somewhere at the turn of 2033-2035 - to deliver and install a power unit on the lunar surface together with our Chinese colleagues," Borisov said.

Solar panels would not be able to provide enough electricity to power future lunar settlements, he said, while nuclear power could.

"This is a very serious challenge...it should be done in automatic mode, without the presence of humans," he said of the possible plan.  READ MORE...

Space Force to Guard the Moon

It's been reported that United States Space Force Commander Gen. Chance Saltzman surveyed the Force's members to develop a mission statement for America's newest military branch. Aside from the novelty of crowdsourcing soldiers as to their interpretation of their mission (which I like but could draw criticism from more constitutionalist folks), the result seems to be on target: "Secure our nation's interests in, from and to space."


However — and with all due respect to the general from this son of a sergeant — I believe his interpretation of at least a part of this statement may be incorrect and informed by a bias that is all too common in the sometimes overly conservative and hallowed halls of the Pentagon.

First, having a simple and concise statement is essential. Shorter is better. Having that statement be co-generated by those forming the first cadres of the Force is an excellent idea to encourage buy-in and ownership.

The term "secure" is also essential. Protecting U.S. national interests is the chief priority of all our military branches, from under the sea to above the sky and all places in between.


He interprets securing that national interest "from space" as the defense of systems and technologies such as communications, navigation and missile warning. In other words, protecting those elements of the defense infrastructure vital to what the military refers to as the "Joint Force" (i.e., all the branches that might be part of a combined military action or activity on Earth).

So far, this is all great stuff. However, what the good general is missing in his reading and interpretation, and perhaps, in what his soldiers are saying (although I bet not, given their probable age demographic), is anything referring to the outward-facing phase of developing space activities without reference to direct support of our on-the-planet military posture and capabilities. In other words, the Space Force's role in securing our national interests beyond low Earth orbit (LEO).   READ MORE...

Three crew-carrying spacecraft are getting ready for their big moon missions.

The Orion capsules for the Artemis 2, Artemis 3 and Artemis 4 moon missions are coming together at NASA's Kennedy Space Center in Florida under stewardship of contractor Lockheed Martin.

"The future of @NASA_Orion is looking pretty good," Lockheed officials wrote on Twitter Friday (July 14) of the three spacecraft, each of which is expected to ferry astronauts to the moon starting in late 2024 or so.

Artemis 2 will send Orion the moon in November 2024 with an already-named crew of four astronauts, while we are still awaiting word of who will fly the Artemis 3 and 4 missions for later in the decade.

Artemis 2 includes NASA astronauts Reid Wiseman, Victor Glover and Christina Koch, along with Canadian Space Agency astronaut Jeremy Hansen. Artemis 3 and 4 will both include astronauts from NASA and the European Space Agency.

Artemis 3 is currently scheduled to launch in 2025 or 2026, pending readiness of the SpaceX Starship system that will ferry some of the crew to the surface. Artemis 4 would then follow later in the 2020s, if current schedules hold.

Lockheed Martin is under contract to deliver Orion spacecraft for future Artemis moon missions across several delivery orders. In recent years, the orders for Artemis 3 through 5 had values of $2.7 billion, while Artemis 6 through 9's order is worth $1.9 billion. Lockheed officials previously stressed that building the spacecraft in groups allows them the company realize cost savings via production efficiencies.  READ MORE...

Our Moon's Hidden Resource


Alongside advances in space exploration, we’ve recently seen much time and money invested into technologies that could allow effective space resource utilisation. And at the forefront of these efforts has been a laser-sharp focus on finding the best way to produce oxygen on the Moon.

In October, the Australian Space Agency and NASA signed a deal to send an Australian-made rover to the Moon under the Artemis program, with a goal to collect lunar rocks that could ultimately provide breathable oxygen on the Moon.

Although the Moon does have an atmosphere, it’s very thin and composed mostly of hydrogen, neon, and argon. It’s not the sort of gaseous mixture that could sustain oxygen-dependent mammals such as humans.

That said, there is actually plenty of oxygen on the Moon. It just isn’t in a gaseous form. Instead, it’s trapped inside regolith — the layer of rock and fine dust that covers the Moon’s surface. If we could extract oxygen from regolith, would it be enough to support human life on the Moon?

THE BREADTH OF OXYGEN
Oxygen can be found in many of the minerals in the ground around us. And the Moon is mostly made of the same rocks you’ll find on Earth (although with a slightly greater amount of material that came from meteors).

Minerals such as silica, aluminium, and iron and magnesium oxides dominate the Moon’s landscape. All of these minerals contain oxygen, but not in a form our lungs can access.

On the Moon, these minerals exist in a few different forms including hard rock, dust, gravel, and stones covering the surface. This material has resulted from the impacts of meteorites crashing into the lunar surface over countless millennia.

Some people call the Moon’s surface layer lunar “soil”, but as a soil scientist, I’m hesitant to use this term. Soil as we know it is pretty magical stuff that only occurs on Earth. It has been created by a vast array of organisms working on the soil’s parent material — regolith, derived from hard rock — over millions of years.

The result is a matrix of minerals which were not present in the original rocks. Earth’s soil is imbued with remarkable physical, chemical, and biological characteristics. Meanwhile, the materials on the Moon’s surface is basically regolith in its original, untouched form.  READ MORE...

Nuclear Reactor on Moon


LONDON — The UK Space Agency said Friday it would back research by Rolls-Royce  looking at the use of nuclear power on the moon.

In a statement, the government agency said researchers from Rolls-Royce had been working on a Micro-Reactor program “to develop technology that will provide power needed for humans to live and work on the Moon.”

The UKSA will now provide £2.9 million (around $3.52 million) of funding for the project, which it said would “deliver an initial demonstration of a UK lunar modular nuclear reactor.”

The new money builds upon £249,000 provided by the UKSA to fund a study in 2022.

“All space missions depend on a power source, to support systems for communications, life-support and science experiments,” it said.

“Nuclear power has the potential to dramatically increase the duration of future Lunar missions and their scientific value.”

Rolls-Royce is set to work with a range of organizations on the project, including the University of Sheffield’s Advanced Manufacturing Research Centre and Nuclear AMRC, and the University of Oxford.

“Developing space nuclear power offers a unique chance to support innovative technologies and grow our nuclear, science and space engineering skills base,” Paul Bate, chief executive of the UK Space Agency, said.

Bate added that Rolls-Royce’s research “could lay the groundwork for powering continuous human presence on the Moon, while enhancing the wider UK space sector, creating jobs and generating further investment.”

According to the UKSA, Rolls-Royce — not to be confused with Rolls-Royce Motor Cars, which is owned by BMW — is aiming “to have a reactor ready to send to the Moon by 2029.”

Dhara Patel, space expert at the National Space Centre in Leicester, England, told CNBC that humans returning to the moon would need “a reliable power source” so astronauts could “live and work on our lunar neighbour for long-term missions.”

“Solar power would seem an obvious choice but the Moon’s rotation results in a two-week day followed by a fortnight of darkness or night time — not ideal,” Patel went on to explain.

“With little air and no liquid water on the surface, other renewable sources of energy aren’t possible,” she said. “Nuclear power could enable a continuous source of power regardless of the physical environment and conditions on the lunar surface.”

Using nuclear power on the moon, Patel noted, could boost the lifetime of lunar missions.  READ MORE...

Earth is Suddenly Spinning Faster


Our planet set a record for completing one rotation faster than scientists had ever previously recorded, according to TimeAndDate.com. Earth rotated once around its axis on Wednesday, June 29, in 1.59 milliseconds less than 24 hours.

Hang on! Earth takes exactly 24 hours to rotate once on its axis, right? Almost, yes, but not exactly.

The International Earth Rotation and Reference Systems Service (IERS) had even begun adding leap seconds every now and again to make up for the slower spin (it last happened on December 31, 2016).

Over a longer time period that may still be the case—Earth’s rotation may, in general, still be slowing down.

After all, the Moon is gradually slowing down the Earth’s rotation. Its gravitational pull causes tides and makes the Earth’s orbital path around the Sun slightly elliptical.  READ MORE...

Moon's Permanent Shadows

Original story reprinted with permission from Quanta Magazine, an editorially independent publication of the Simons Foundation whose mission is to enhance public understanding of science by covering research develop­ments and trends in mathe­matics and the physical and life sciences.



ON OCTOBER 9, 2009, a 2-ton rocket smashed into the moon traveling at 9,000 kilometers per hour. As it exploded in a shower of dust and heated the lunar surface to hundreds of degrees Celsius, the jet-black crater into which it plummeted, called Cabeus, briefly filled with light for the first time in billions of years.

The crash was no accident. NASA’s Lunar Crater Observation and Sensing Satellite (LCROSS) mission aimed to see what would be kicked up from the lunar shadows by the impact. A spacecraft trailing the rocket flew through the dust plume to sample it, while NASA’s Lunar Reconnaissance Orbiter observed from afar. The results of the experiment were astonishing: Scientists detected 155 kilograms of water vapor mixed into the dust plume. They had, for the first time, found water on the moon. “It was absolutely definitive,” said Anthony Colaprete of NASA’s Ames Research Center, the principal investigator of LCROSS.

The moon isn’t an obvious reservoir of water. “It’s really weird when you stop to think about it,” said Mark Robinson, a planetary scientist at Arizona State University. Its lack of atmosphere and extreme temperatures should cause any water to almost instantly evaporate. Yet about 25 years ago, spacecraft began to detect signatures of hydrogen around the moon’s poles, hinting that water might be trapped there as ice. LCROSS proved this theory. Scientists now think there’s not just a bit of water ice on the moon; there are 6 trillion kilograms of it.  READ MORE...

Putting a Nuclear Reactor on the Moon

power for human exploration of the Moon under Artemis. Credits: NASA


NASA is one step closer to finalizing nuclear power some 238,900 miles away from Earth.

The space agency and the U.S. Department of Energy have selected three design concept proposals for a fission surface power system that would be stationed on the moon.

The hope is that a nuclear reactor would produce the power needed to operate rovers, conduct experiments and help support life.


Scientists say that the concepts for the technology will benefit future exploration under the Artemis umbrella and will be ready to launch by the end of the decade.

The contracts fund the development of initial design concepts for a 40-kilowatt class fission power system planned to last at least 10 years in the lunar environment and valued at approximately $5 million each, NASA says. Forty kilowatts of power is enough to run 30 households for ten years continuously.  READ MORE...

Mysterious Impact Site on Moon

Artist’s animation of a rocket booster crashing into the moon.


Astronomers discovered a rocket body heading toward a lunar collision late last year. Impact occurred on March 4, 2022, with NASA’s Lunar Reconnaissance Orbiter (LRO) later spotting the resulting crater. 

Surprisingly the crater is actually two craters, an eastern crater (18-meter diameter, about 19.5 yards) superimposed on a western crater (16-meter diameter, about 17.5 yards).

The double crater was unexpected and may indicate that the rocket body had large masses at each end. Typically a spent rocket has mass concentrated at the motor end; the rest of the rocket stage mainly consists of an empty fuel tank. 

Since the origin of the rocket body remains uncertain, the double nature of the crater may indicate its identity.

No other rocket body impacts on the Moon created double craters. The four Apollo SIV-B craters were somewhat irregular in outline (Apollos 13, 14, 15, 17) and were substantially larger (greater than 35 meters, about 38 yards) than each of the double craters. 

The maximum width (29 meters, about 31.7 yards) of the double crater of the mystery rocket body was near that of the S-IVBs.  READ MORE...

Death Spiraling Moon

NASA’s Perseverance rover has captured the clearest ever footage of a solar eclipse over Mars, and the results are out of this world.

The rover snapped the ethereal video of Mars’ potato-shaped moon, Phobos, moving across the face of the sun on April 2. During the eclipse, Phobos projected its uneven shadow over the Martian surface — appearing almost as though it was the pupil of a gigantic eyeball rolling in its socket.

Perseverance recorded the footage midway through its journey to a river delta on Mars’ 28-mile-wide (45 kilometers) Jezero Crater, where it will search for evidence of life on the Red Planet. Training its state-of-the-art Mastcam-Z camera on the sky, the rover recorded the misshapen moon’s solar transit with the greatest zoom and at the highest framerate ever.

"I knew it was going to be good, but I didn't expect it to be this amazing," Rachel Howson, a mission operations specialist at Malin Space Science Systems and one of the Mastcam-Z team members who operates the camera, said in a statement.

Phobos, named after the Greek god of fear, is roughly 157 times smaller than Earth's moon and is one of Mars' two natural satellites, alongside the even smaller Deimos (whose name comes from the Greek god of dread).

Scientists believe that the brother moons were once roaming asteroids that were snared into Mars’ orbit by the planet’s gravitational field. The orbits of these captive asteroids are unstable, according to researchers, and scientists predict that in a few tens of millions of years' time Deimos will spin out into space while Phobos will slam into Mars’ surface.  READ MORE...

Controlling the Moon

In 1961, U.S. President John F. Kennedy declared that his nation would be the first to land a man on the moon. That ambitious goal would later be fulfilled as two NASA astronauts took wobbly steps across the lunar surface on July 20, 1969, much to the dismay of Russia’s own space program leaders.

More than 60 years later, a new space race to the moon has begun, albeit with much higher stakes and brand new players ready to make the 238,855-mile journey. This time, the race to the moon is about much more than just planting a flag on its dusty surface. Getting to the moon first could also mean calling dibs on its limited resources, and controlling a permanent gateway to take humans to Mars—and beyond.

Whether it’s NASA, China, Russia, or a consortium of private companies that end up dominating the moon, laying claim to the lunar surface isn’t really about the moon anyway—it’s about who gets easier access to the rest of the solar system.

Everyone’s Got an Agenda

James Rice, a senior scientist at the School of Earth and Space Exploration at Arizona State University, remembers growing up with the Apollo program and getting bitten by the space bug as he watched the 1969 moon landing unfold on television.

“As a kid, I saw that happening and I wanted to be a part of it,” Rice told The Daily Beast. “That’s basically why I’m in this career today.”

As Rice reflected on the current space race, he recognized some key differences. “Things have really changed dramatically in terms of the technology and the players that are out there,” he said. “This is not the moon we thought of during the Apollo days.” Scientists have learned so much more about the moon through more detailed analysis of lunar samples, as well as several missions that have probed exactly what might be sitting on the moon’s surface and remain hidden deep underground.  READ MORE...

Toyota Heading to the Moon


TOKYO (AP) — Toyota is working with Japan’s space agency on a vehicle to explore the lunar surface, with ambitions to help people live on the moon by 2040 and then go live on Mars, company officials said Friday.

The vehicle being developed with the Japan Aerospace Exploration Agency is called Lunar Cruiser, whose name pays homage to the Toyota Land Cruiser sport utility vehicle. Its launch is set for the late 2020’s.

The vehicle is based on the idea that people eat, work, sleep and communicate with others safely in cars, and the same can be done in outer space, said Takao Sato, who heads the Lunar Cruiser project at Toyota Motor Corp.

“We see space as an area for our once-in-a-century transformation. By going to space, we may be able to develop telecommunications and other technology that will prove valuable to human life,” Sato told The Associated Press.

Gitai Japan Inc., a venture contracted with Toyota, has developed a robotic arm for the Lunar Cruiser, designed to perform tasks such as inspection and maintenance. Its “grapple fixture” allows the arm’s end to be changed so it can work like different tools, scooping, lifting and sweeping.  READ MORE...
