To name something is to begin the process of humanising it; so we named the space between the earth and the moon as the Lake Eden Eye so that the International Space Station is not just in 'space' but in/on the Lake Eden Eye.

||August 23: 2017 || ά. This crew of six is midway through a simulated expedition on the Moon, based at the new Habitat Lunares base in Poland. The only facility of its kind in Europe, this privately run habitat is a simulated lunar base set up in a former military airport in Pila in northwest Poland. The crew stays on the base for two weeks at a time, physically cut off from the external world. Lunares has no windows, is run on lunar time and its occupants can leave only by venturing into an adjoining hanger, which is filled with Moon-like basalt rocks for simulated Moonwalks.

This Lunar Expedition One is the second of four expeditions this year, lasting August 15-29. The mission is controlled from ESA’s technical centre in Noordwijk, the Netherlands, focusing on exploring changes to the crew’s biological clocks during their stay. It performs scheduling, communicates with the base and oversees lighting inside the habitat. “The analogue astronauts are completely cut off from external light sources. Instead, we control the base’s automated lighting systems.” explains Ms Agata Kolodziejczyk, Research Fellow in ESA’s Advanced Concepts Team, who led the establishment of the habitat as part of her research into ‘time architecture’ for future off-planet bases.

“I regard Lunares as an extremely valuable new chronobiological laboratory for Europe, with full bioethical committee agreements in place. We’ll be checking how the participants’ subjective time perception alters with the changes we induce. The habitat contains an LED light system providing a shifting combination of colours throughout the day, to mimic changes in sunlight. We’re extending the length of this artificial ‘day’ to put their circadian rhythms out of alignment and induce jet lag.

But we’re, also, testing new prototypes of ‘physiological lights’, that emit in the ultraviolet, which penetrates through the retina to the brain’s pineal gland, to see if this is sufficient to reset their body clocks.”

A survey of US Space Shuttle crews found that half depended on medication to go to sleep in orbit, while other space-dwellers have reported disrupted body clocks, a condition, that has been linked to various health problems. Redesigned lighting systems, that fit better with human physiology should result in happier, healthier astronauts, lighting aboard the International Space Station has recently been updated for this very reason.

In parallel, more than 20 other experiments are, also, under way. ESA and the International Lunar Exploration Working Group supplied the ExoGeoLab lander, as well as, a telescope for use during simulated Moonwalks.

Polish ESA Young Graduate Trainee Mr Mateusz Kraiński has, also, built a rover and simulator system in his free time. This Netherlands-based rover is being controlled remotely by the crew from Poland.

|| June 15: 2017 || ά. The last manned mission to the Moon took place in December 1972. Although several probes have targeted the Moon since then, we humans have concentrated on living and working in low Earth orbit and on exploring the rest of the Solar System with some ambitious robotic missions. Today, the general view shared by Earth's space agencies is changing. The exploration of outer space is still high on everybody's list but it has become apparent that many future space activities will require a human presence on the Moon first.

So far, no humans have ever been to the polar regions of the Moon, where unmanned missions have found water in the form of ice. Water is an important resource because it can be used to produce oxygen, which will be vital for human survival on the Moon. But what does this all mean? If we are going to return to the Moon, astronauts will need somewhere to live, in a safe and stable environment. A new study launched under ESA’s General Studies Programme:GSP, called, ‘Conceiving a lunar base using three-D printing technologies’, is set to find out ways of creating habitable structures using all resources available at the destination.

The study is looking into additive manufacturing or three-D printing technology from a wider perspective, including the ancillary equipment needed to operate this and the high-level requirements to ultimately achieve a lunar habitat. Several studies have been carried out by different space agencies to see how humans could survive on the Moon. In this respect, additive manufacturing or three-D printing has been identified as one of the most promising applications for building structures on the Moon.

Lunar soil as a base material for a three-D printer has already been used to fabricate honeycomb-like bricks from which all kinds of useful structures can be made. An even faster way of producing a lunar habitat would make use of an inflatable base that can be covered layer-by-layer with lunar soil or ‘regolith’ to create a protective shell.

However, these studies have focused on conceptual designs, often based on single elements, rather than taking into account the overall needs in terms of energy, collection and transportation of the regolith, machinery and so on.

This new GSP study is to analyse the possibilities of using additive manufacturing for the realisation of a lunar base, including the production of internal equipment for the crew, the processing of food based on a limited number of basic elements and the possibility of making spare parts needed to maintain such base. It will address technologies, that could be used in a lunar environment and investigate the developmental needs of three-D printing to ensure a sustainable, safe place for astronauts on the Moon. ω.

Look Out for the Asteroid to Fly by Mother Earth: April 19

Image: NASA Video-Capture

 

|| April 09: 2017 || ά. A relatively large near-Earth asteroid discovered nearly three years ago will fly safely past Earth on April 19 at a distance of about 01.1 million miles or 01.8 million kilometres or about 04.6 times the distance from Earth to the moon. Although, there is no possibility for the asteroid to collide with our planet, this will be a very close approach for an asteroid of this size. The asteroid, known as 2014JO25, was discovered in May 2014 by astronomers at the Catalina Sky Survey near Tucson, Arizona, a project of NASA's NEO Observations Programme in collaboration with the University of Arizona.

An NEO is a near-Earth object. Contemporary measurements by NASA's NEOWISE mission indicate that the asteroid is roughly 2,000 feet, 650 metres in size and that its surface is about twice as reflective as that of the moon. At this time very little else is known about the object’s physical properties, even though, its trajectory is well known. The asteroid will approach the Earth from the direction of the sun and will become visible in the night sky after April 19. It is predicted to brighten to about magnitude 11, when it could be visible in small optical telescopes for one or two nights before it fades as the distance from the Earth rapidly increases.

Small asteroids pass within this distance of the Earth several times each week but this upcoming close approach is the closest by any known asteroid of this size or larger, since asteroid Toutatis, a 03.1-mile, five-kilometre asteroid, which approached within about four lunar distances in September 2004. The next known encounter of an asteroid of comparable size will occur in 2027 when the half-mile-wide, 800-metre-wide asteroid 1999 AN10 will fly by at one lunar distance, about 236,000 miles, 380,000 kilometres.

The April 19 encounter provides an outstanding opportunity to study this asteroid, and astronomers plan to observe it with telescopes around the world to learn as much about it as possible. Radar observations are planned at NASA's Goldstone Solar System Radar in California and the National Science Foundation’s Arecibo Observatory in Puerto Rico, and the resulting radar images could reveal surface details as small as a few meters.

The encounter on April 19 is the closest this asteroid has come to Earth for at least the last 400 years and will be its closest approach for at least the next 500 years. Further, on April 19, the comet PanSTARRS:C:2015ER61 will make its closest approach to the Earth, at a very safe distance of 109 million miles, 175 million kilometres. A faint fuzzball in the sky when it was discovered in 2015 by the Pan-STARRS NEO survey team using a telescope on the summit of Haleakala, Hawaii, the comet has brightened considerably due to a recent outburst and is now visible in the dawn sky with binoculars or a small telescope.

To Survive the Long Dark Lunar Night: Will You Sing to the Earth

A high-definition image of Earth taken by Japan’s Kaguya lunar orbiter in November 2007.Image: JAXA: NHK

 

|| March 24: 2017 || ά. Designers of the future Moon missions and bases have to contend with a chilling challenge: how might their creations endure the fortnight-long lunar night? ESA has arrived at a low-cost way of surviving. During prolonged night, when the surface is lit only by blue Earthlight, temperatures dip below –170ºC. Some locations at higher latitudes have shorter nights, though others have much longer or even permanent darkness.

Numerous robotic missions have perished during this prolonged cold. Russia’s Lunokhod-tworover, for instance, failed to make it through the night in May 1973, its radioactive heater having gradually run down after four months of exploring. The Apollo manned missions stayed on the surface only a few days at a time and all during the early lunar morning. But future lunar settlers will have to live in the night as well as the day, bearing in mind that vital solar energy and heat would be unavailable during the 14 days of darkness.

“Up until now, radioactive heat and power sources have been the preferred solution for lunar habitats.” explains ESA’s Moritz Fontaine. “But these would multiply the cost and complexity of any expedition. So we’re exploring a more sustainable solution, using the capacity of moondust to absorb and store energy when hit by sunlight, then releasing this energy during the lunar night.”

Driven by the temperature difference, this heat engine would be kept running directly by the heat of the Sun during the day, illuminated surface temperatures rise well above 100ºC at the equator while simultaneously storing excess heat in the soil.

Once night falls, the heat engine would be kept running in turn by the gradual release of the energy from the heated soil. “The principle has been worked out in detail.” adds Moritz. “The next step, being undertaken through ESA’s General Studies Programme, is to perform numerical and simulation studies to put values on the heat storage and electricity provision the system would enable.

“The results should then allow the construction of a small demonstrator to test the concept in practice.”

Cogito Ergo Sum: Descartes: The First Lunar Meditation

 Temple atop Shackleton Crater: Image: Jorge Mañes Rubio. Spatial design and visualisation in collaboration with DITISHOE


|| January 26: 2017 || ά.  A near-perpetually sunlit peak close to the Moon’s south pole has been selected by ESA’s artist-in-residence as the site of a building like no other. Artist Jorge Mañes Rubio, part of ESA’s future-oriented Advanced Concepts Team:ACT, has designed a place of contemplation to serve a future lunar settlement. It would be built on the sunlit rim of Shackleton Crater, which is bathed much of the time in sunlight while overlooking a 04.2 km-deep interior mired in perpetual shadow.

The lunar poles have previously been identified as promising locations for future settlement because craters kept shaded by the lowness of the Sun in the local sky are thought to serve as ‘cold traps’ to preserve water ice, potentially a vital source of water, air or rocket fuel. The first building has yet to be erected on the Moon, and most designs for lunar buildings have been strictly functional in purpose: places to live, work or perform research.

“I’ve been having all sorts of discussions with my ACT colleagues, including speculating on the likely needs of future lunar settlers.” explains Jorge. “What kind of social interactions will they share, what cultural activities and rituals will they have, and what sort of art and artefacts will they be producing? Humans have been creating art for at least 30,000 years, so I have no doubt this will continue in space and on the Moon.

These discussions have been very valuable and stimulating, since they lead us to consider aspects of human exploration that aren’t usually considered by scientists and engineers.” adds Leopold Summerer, heading the ACT. “To benefit fully from Jorge’s creativity, it was important to give him full artistic freedom on what and how he would do.”

What Jorge terms his ‘Moon Temple’ is intended as a symbol of unity for humankind, reflecting the pull that our natural satellite has always had on the human imagination. “Lunar settlement represents a perfect chance for a fresh start, a place where there are no social conventions, no nations and no religion, somewhere where these concepts will need to be rethought from scratch.

Humans have brought flags to the Moon, but they’ve been bleached white by sunlight since then, almost as if the Moon is protecting itself from such terrestrial concepts. So this Temple is intended as a mythic and universal structure that can hopefully bring people together in this new environment in novel ways.”

At the same time, the 50 m-high domed structure is also something that could one day be built. Jorge talked to ESA materials specialists studying 3D printing of lunar soil. “The result might resemble ‘abode’ architecture, an ancient method of building that is still made use to this day.” adds Jorge.

“This was a big source of inspiration for me, along with 18th century utopian architects such as Étienne-Louis de Boullée and Claude Nicolas Ledoux, who designed massive structures too large to be feasibly built on Earth but practical in the Moon’s one-sixth gravity.”

Similarly, the Temple’s free-standing dome would eventually collapse under its own weight on Earth, but could endure on the Moon. Jorge put similar thought into the site of his building: he selected Shackleton over nearby Malapert Crater because Earth is perpetually visible from Malapert, while from Shackleton it will only be seen for two weeks at a time, inspiring more independent thinking.

One opening in the dome will look Earthwards, while another at the top will peer out into deep space. As a next step, Jorge aims to create small sculptures and artefacts out of simulated lunar materials, inspired by the simulated lunar environment at ESA’s European Astronaut Centre near Cologne, Germany. ω.

The December Moon with  Some Green Neighbour

|| December 18: 2016|| ά. This is the best ever we have seen the moon from an earthling's perspective and definitely, the best ever image of the moon that we have ever taken. That was on December 11. The only issue is, with this clarity of the image, that green neighbour, is somewhat of a mystery! No idea who that celestial neighbour is or whether that's just a camera-blur.

What can be visible is the most beautiful almost milky emerald glow-ring around the moon. Just, don't run away with the ring nor with the spoon, even if the cow wants to jump! But, you are welcome to remain on Mother Earth and have a look at what the researchers have found out about the water cycle and how that impacts of the rain and the dry, over there, in The Earth. ω.

Hadley Rille on the Moon, Seen by SMART-01

Hadley Rille on the Moon, seen by SMART-01: Released 25.07.2016 11:29: Image: ESA:Space-X:Space Exploration Institute

|| August 21: 2016|| ά. This strangely meandering channel, carved on the Moon, is one of the most famous features on our nearest celestial neighbour. It shot to fame in July 1971 when the two astronauts of Apollo 15 drove their lunar rover to its very edge.

Known as Hadley Rille, the feature is named after the 18th century British mathematician and inventor John Hadley. In 1721, Hadley presented a telescope that used a non-spherical mirror to the Royal Society in London. Shaped as a parabola, the mirror avoided the aberration caused by a spherical mirror, and set the shape for all telescope mirrors to come.

Hadley Rille is thought to have been carved by an ancient lava flow, dating back just over 03 billion years to soon after the Moon formed. It stretches more than 120 km, up to 1500 m wide and more than 300 m deep in some places.

From their close-up position, the Apollo astronauts photographed what looked like strata in the walls of the rille. This suggests that there were many volcanic eruptions, each building a new layer. Then, a channel of lava cut through these deposits. When it drained away, it left the sinuous rille we see today. However, planetary scientists are not entirely sure of the details of the process.

This image was taken by ESA’s SMART-01, which explored the Moon from 2004 to 2006. Its miniaturised camera demonstrated that smaller equipment could still provide first-class science.

This image was taken from an altitude of about 2000 km. It spans about 100 km and shows the region around Hadley Rille centred at about 25°N / 3°E.

SMART-01 was ESA’s first mission to the Moon. It tested new engine technologies, including a solar electric propulsion system that will carry ESA’s BepiColombo mission to Mercury in 2018.

At the end of its mission, SMART-01 was flown closer and closer to the lunar surface until it was intentionally crashed on September 03, 2006. During its mission, it had completed more than 2000 orbits of the Moon. ω.

Clair de Lune

Image: NASA

|| May 08: 2016 || The regular daily and monthly rhythms of Earth's only natural satellite, the moon, have guided timekeepers for thousands of years. Its influence on Earth's cycles, notably tides, has been charted by many cultures in many ages. The moon moderates Earth's wobble on its axis, leading to a relatively stable climate over billions of years. From Earth, we always see the same face of the moon because the moon is spinning on its axis at the same speed that it is going around Earth, that is, it is in synchronous rotation with Earth.

The light areas of the moon are known as the highlands. The dark features, called maria (Latin for seas), are impact basins that were filled with lava between 4.2 and 1.2 billion years ago. These light and dark areas represent rocks of different composition and ages, which provide evidence for how the early crust may have crystallized from a lunar magma ocean. The craters themselves, which have been preserved for billions of years, provide an impact history for the moon and other bodies in the inner solar system.

NASA/Zuber, M.T. et al., Nature, 2012


The leading theory of the moon's origin is that a Mars-sized body collided with Earth approximately 4.5 billion years ago, and the resulting debris from both Earth and the impactor accumulated to form our natural satellite. The newly formed moon was in a molten state. Within about 100 million years, most of the global "magma ocean" had crystallized, with less-dense rocks floating upward and eventually forming the lunar crust. The early moon may have developed an internal dynamo, the mechanism for global magnetic fields for terrestrial planets.

Since the ancient time of volcanism, the arid, lifeless moon has remained nearly unchanged. With too sparse an atmosphere to impede impacts, a steady rain of asteroids, meteoroids, and comets strikes the surface. Over billions of years, the surface has been ground up into fragments ranging from huge boulders to powder. Nearly the entire moon is covered by a rubble pile of charcoal-gray, powdery dust and rocky debris called the lunar regolith. Beneath is a region of fractured bedrock referred to as the megaregolith.

The moon was first visited by the U.S.S.R.'s Luna 1 and Luna 2 in 1959, and a number of U.S. and U.S.S.R. robotic spacecraft followed. The U.S. sent three classes of robotic missions to prepare the way for human exploration: the Rangers (1961-1965) were impact probes, the Lunar Orbiters (1966-1967) mapped the surface to find landing sites, and the Surveyors (1966-1968) were soft landers. The first human landing on the moon was on 20 July 1969. During the Apollo missions of 1969-1972, 12 American astronauts walked on the moon and used a Lunar Roving Vehicle to travel on the surface and extend their studies of soil mechanics, meteoroids, lunar ranging, magnetic fields, and solar wind. The Apollo astronauts brought back 382 kilograms (842 pounds) of rock and soil to Earth for study.

After a long hiatus, lunar exploration resumed in the 1990s with the U.S. robotic missions Clementine and Lunar Propspector. Results from both missions suggested that water ice might be present at the lunar poles, but a controlled impact of the Prospector spacecraft produced no observable water.

The European Space Agency was first in the new millennium with SMART-1 in 2003, followed by Kaguya (Japan), Chang'e-1 (China), and Chandrayaan-1 (India) in 2007-2008. The U.S. began a new series of robotic lunar missions with the joint launch of the Lunar Reconnaissance Orbiter (LRO) and Lunar Crater Observation and Sensing Satellite (LCROSS) in 2009. In 2011, a pair of repurposed spacecraft began the ARTEMIS (Acceleration, Reconnection, Turbulence, and Electrodynamics of the moon's Interaction with the Sun) mission. In 2012, the Gravity Recovery and Interior Laboratory (GRAIL) twin spacecraft studied the moon's gravity field and produced the highest-resolution gravity field map of any celestial body.

How the Moon Got its Name

Earth's only natural satellite is simply called the moon because people didn't know other moons existed until Galileo Galilei discovered four moons orbiting Jupiter in 1610. Other moons in our solar system are given names so they won't be confused with each other. We call them moons because, like our own, they are natural satellites orbiting a solar system body (which in turn is orbiting a star).

||April 14, 2016 || On March 16, 1966, command pilot Neil Armstrong and pilot David Scott successfully docked their Gemini VIII spacecraft with the Agena target vehicle, the first-ever linking of two spacecraft together in Earth orbit. This crucial spaceflight technology milestone would prove vital to the success of future moon landing missions. Catching up with already-orbiting spacecraft also has been essential during missions to the International Space Station.

The astronauts aboard the Gemini spacecraft took this side view photograph of the Agena target vehicle at a distance of 45 feet during an inspection prior to docking. The two spacecraft were in the third orbit of the mission, above the west coast of Mexico.

Because of problems with the Gemini spacecraft control system, the crew was forced to undock after approximately 30 minutes, as the spacecraft-target vehicle combination had begun to encounter increasing yaw and roll rates. The crew regained control of their spacecraft by using the reentry control system (RCS), and the decision was made in Mission Control to follow mission rules that dictated once the RCS was activated, the crew must be brought home. The Gemini VIII landed early in a secondary landing area in the Pacific, splashing down within two miles of the predicted impact point 10 hours, 41 minutes after liftoff.

||April 11, 2016 ||New science results from NASA’s Lunar Atmosphere and Dust Environment Explorer, or LADEE, mission indicate that the moon is engulfed in a permanent, but lopsided, dust cloud that increases in density when annual events like the Geminids meteor shower spew shooting stars, according to a new study led by University of Colorado Boulder.

"Knowledge about the dusty environments in space has practical applications," said CU-Boulder physics Professor Mihaly Horanyi. "Knowing where the dust is and where it is headed in the solar system could help mitigate hazards for future human exploration, including dust particles damaging spacecraft or harming astronauts."

The cloud was discovered using data from a detector on board LADEE called the Lunar Dust Experiment (LDEX) designed and built by CU-Boulder. LDEX charted more than 140,000 impacts during the six-month long mission, which launched in September 2013 and orbited the moon for about six months. NASA’s Ames Research Center in Moffett Field, California, was responsible for spacecraft design, development, testing and mission operations, in addition to managing the overall mission.

“The LDEX team has been painstakingly analyzing their data since the LADEE mission ended on April 18, 2014,” said LADEE project scientist at Ames, Rick Elphic. “Their results answer one of the big LADEE science questions: is there a dust component to the tenuous lunar atmosphere? And if so, why is it there?”

According to Horanyi, the cloud is primarily made up of tiny dust grains kicked up from the moon’s surface by the impact of high-speed, interplanetary dust particles. A single dust particle from a comet striking the moon’s surface lofts thousands of smaller dust specks into the airless environment, and the lunar cloud is maintained by regular impacts from such particles.

“Identifying this permanent dust cloud engulfing the moon was a nice gift from this mission,” said Horanyi, the principal investigator on LDEX and the lead author of the study. “We can carry these findings over to studies of other airless planetary objects like the moons of other planets and asteroids.”

A paper on the subject appears in the June 17 issue of Nature. Co-authors on the study include Jamey Szalay, Sascha Kempf, Eberhard Grun and Zoltan Sternovsky from CU-Boulder, Juergen Schmidt from the University Oulu in Finland, and Ralf Srama from the University of Stuttgart in Germany.

The first hints of a cloud of dust around the moon came in the late 1960s when NASA cameras aboard unmanned moon landers captured a bright glow during lunar sunsets. Several years later, Apollo astronauts orbiting the moon reported a significant glow above the lunar surface when approaching sunrise, a phenomenon brighter than the sun alone should have been able to create at that location.

Since the new findings don’t square with the Apollo reports of a thicker, higher dust cloud, conditions back then may have been somewhat different. The dust on the moon -- which is dark and sticky and regularly dirtied the suits of moonwalking astronauts -- was created over several billion years as interplanetary dust particles incessantly pounded the rocky lunar surface.

Many of the cometary dust particles impacting lunar surface are traveling at thousands of miles per hour in a retrograde, or counterclockwise orbit around the sun, the opposite orbital direction of the solar system’s planets. This causes high-speed, near head-on collisions with the dust particles and the moon’s leading surface as the Earth-moon system travel together around the sun .

||April 10, 2016||NASA’s Lunar Reconnaissance Orbiter (LRO) has completed a maneuver that lowered the spacecraft’s orbit to within 20 kilometers (12 miles) above areas near the lunar South Pole, the closest the spacecraft has ever been to the lunar surface.

On Monday, May 4, 2015 flight controllers at NASA’s Goddard Space Flight Center in Greenbelt, Maryland performed two station keeping burns to change LRO’s orbit. The new orbit allows LRO to pass within 20 km (12 miles) of the South Pole and 165 km (103 miles) over the North Pole.

"We're taking LRO closer to the moon than we've ever done before, but the maneuver is similar to all other station keeping maneuvers, so the mission operations team knows exactly what to do,” said Steve Odendahl, LRO mission manager from NASA Goddard.

To optimize science return, team members made the decision to change the orbit after determining that the new orbit configuration poses no danger to the spacecraft. LRO can operate for many years at this orbit.

The new orbit enables exciting new science and will see improved measurements near the South Pole. Two of the instruments benefit significantly from the orbit change. The return signal from the Lunar Orbiter Laser Altimeter (LOLA) laser shots will become stronger, producing a better signal. LOLA will obtain better measurements of specific regions near the South Pole that have unique illumination conditions. Diviner will be able to see smaller lunar features through the collection of higher resolution data.

“The lunar poles are still places of mystery where the inside of some craters never see direct sunlight and the coldest temperatures in the solar system have been recorded,” said John Keller, LRO project scientist at NASA Goddard. “By lowering the orbit over the South Pole, we are essentially magnifying the sensitivity of the LRO instruments which will help us understand the mechanisms by which water or other volatiles might be trapped there.”

Launched on June 18, 2009, LRO has collected a treasure trove of data with its seven powerful instruments, making an invaluable contribution to our knowledge about the moon. LRO is managed by NASA's Goddard Space Flight Center in Greenbelt, Maryland, for the Science Mission Directorate at NASA Headquarters in Washington.

Ancient Polar Ice Reveals Tilting of Earth’s Moon

March 24, 2016: Did the “man in the moon” look different from ancient Earth?

New NASA-funded research provides evidence that the spin axis of Earth’s moon shifted by about five degrees roughly three billion years ago. The evidence of this motion is recorded in the distribution of ancient lunar ice, evidence of delivery of water to the early solar system.

“The same face of the moon has not always pointed towards Earth,” said Matthew Siegler of the Planetary Science Institute in Tucson, Arizona, lead author of a paper in today’s journal Nature. “As the axis moved, so did the face of the ‘man in the moon.’ He sort of turned his nose up at the Earth.”

This interdisciplinary research was conducted across multiple institutions as part of NASA’s Solar System Exploration Research Virtual Institute (SSERVI) based at NASA’s Ames Research Center in Silicon Valley, California.

Water ice can exist on Earth’s moon in areas of permanent shadow. If ice on the moon is exposed to direct sunlight it evaporates into space. Authors of the Nature article show evidence that a shift of the lunar spin axis billions of years ago enabled sunlight to creep into areas that were once shadowed and likely previously contained ice.

The researchers found that the ice that survived this shift effectively “paints” a path along which the axis moved. They matched the path with models predicting where the ice could remain stable and inferred the moon’s axis had moved by approximately five degrees. This is the first physical evidence that the moon underwent such a dramatic change in orientation and implies that much of the polar ice on the moon is billions of years old.

“The new findings are a compelling view of the moon’s dynamic past,” said Dr. Yvonne Pendleton, director of SSERVI, which supports lunar and planetary science research to advance human exploration of the solar system through scientific discovery. “It is wonderful to see the results of several missions pointing to these insights.”

The authors analyzed data from several NASA missions, including Lunar Prospector, Lunar Reconnaissance Orbiter (LRO), Lunar Crater and Observation Sensing Satellite (LCROSS), and the Gravity Recovery and Interior Laboratory (GRAIL), to build the case for a change in the moon’s orientation. Topography from the Lunar Orbiter Laser Altimeter (LOLA) and thermal measurements from the Diviner lunar radiometer – both on LRO – are used to aid the interpretation of Lunar Prospector neutron data that support the polar wander hypothesis.

Siegler noticed that the distribution of ice observed at each of the lunar poles appeared to be more related to each other than previously thought. Upon further investigation, Siegler – and co-author Richard Miller of the University of Alabama at Huntsville – discovered that ice concentrations were displaced from each pole by the same distance, but in exactly opposite directions, suggesting the spin axis in the past was tilted from what we see today. A change in the tilt means that some of the ice deposited long ago has since evaporated as it was exposed to sunlight, but those areas that remain in permanent shadow between the old orientation and the new one retain their ice, and thus indicate what happened.

The reorientation from that ancient spin pole (red arrow) to the present-day spin pole (blue arrow) was driven by the formation and evolution of the Procellarum—a region on the nearside of the Moon associated with a high abundance of radiogenic heat producing elements (green), high heat flow, and ancient volcanic activity.

A planetary body can shift on its axis when there is a very large change in mass distribution. Co-author James Keane, of the University of Arizona in Tucson, modelled the way changes in the lunar interior would have affected the moon’s spin and tilt. In doing so, he found the Procellarum region on the lunar near-side was the only feature that could match the direction and amount of change in the axis indicated by the ice distributions near the poles. Furthermore, concentrations of radioactive material in the Procellarum region are sufficient to have heated a portion of the lunar mantle, causing a density change significant enough to reorient the moon.

Some of this heated mantle material melted and came to the surface to form the visible dark patches that fill large lunar basins known as mare. It’s these mare patches that give the man in the moon his “face.”

Siegler, Miller, and co-author David Lawrence of Johns Hopkins Applied Physics Laboratory in Laurel, Maryland are part of the Volatiles, Regolith and Thermal Investigations Consortium for Exploration and Science team, one of nine teams funded by SSERVI.

Said Siegler, “These findings may open the door to further discoveries on the interior evolution of the moon, as well as the origin of water on the moon and early Earth.”
