This story is a part of To the Moon, a collection exploring humanity’s first journey to the lunar floor and our future residing and dealing on the moon.
When the primary astronomers turned their eyes to the heavens, tens of 1000’s of years in the past, their view was unobscured by the glow of metropolis lights. At evening, a pristine black sheet stretched throughout an unreachable ceiling overhead. The centerpiece of this historical nightscape was a flat gray disc that hung within the sky: the moon.
We used to worship the moon, inform one another tales to clarify its mysteries. In Australia, the Indigenous Yolngu folks named it “Ngalindi,” believing a full moon represented an indolent, pot-bellied man with a number of wives. Because the moon cycled via its phases, the Yolngu believed Ngalindi’s wives had taken to his physique with their axes, slicing items away, leaving solely a crescent slither. Related tales abound in Aztec tradition and the myths of historical Mesopotamia, East Asia, India and Greece.
However on July 20, 1969, we stepped onto a lunar sea and noticed the moon’s floor, up shut, for the very first time. The bottom was useless and cratered. Solely dusty plains stretched out earlier than us.
The moon was now not a god to be worshiped. It was a vacation spot. A spot we may go to, an object we may contact.
Over the following three years, 12 people walked on the floor of the moon, piloting rovers throughout Rima Hadley and Stone Mountain. They pilfered moon soil, studied rocks, visited affect craters and planted flags. On Dec. 14 1972, NASA astronauts within the Apollo 17 mission climbed again into their lunar spacecraft and departed the moon for Earth. It was the final time people ever set foot on the moon.
However in 2019, the moon is being probed and explored as soon as once more. In January, China landed the primary spacecraft on the far aspect of the moon. Israel’s Beresheet lander turned the primary non-public spacecraft to succeed in the moon, crashing onto its floor in April. And NASA doubled down on efforts to put people again on the moon earlier than 2025 “by any means obligatory.” It is an bold purpose, with the hope of creating a everlasting human presence on the moon and in lunar orbit on the finish of the following decade.
The instant way forward for the moon will see us construct on these first steps taken in July 1969. We’ll ship extra robotic landers and rovers to conduct experiments on our behalf. China already has one other Chang’e mission deliberate for this 12 months and India, too, will look to land on the floor earlier than the tip of the 12 months. In our stead, the robots will seek for water and discover the lunar highlands for the sources obligatory to ascertain a extra everlasting presence.

Wanting additional forward, we’ll put together to really colonize the moon. We’ll mine the sublunar layers and smelt its rock for metals and oxygen. We’ll stay at its poles, erecting inflatable shelters, communications facilities and laboratories, and performing experiments not attainable from the floor of the Earth. Finally, we’ll depart for additional into the cosmos and discover our method to Mars.
However it begins with the moon.
What follows is a decade-by-decade account of the way forward for our moon, that includes the ideas and concepts of a number of the world’s main scientists, astronomers, area archeologists, sci-fi authors and futurists. Predicting the long run is nigh on unimaginable. Who would have thought in 1972 that we would not return to the moon for no less than 50 years? Actually, we’ll get it mistaken. Already, there are doubts about NASA’s coming moon missions, with delays and budgetary deficiencies stifling progress.
However advancing our exploration of the moon requires us to assume past simply returning. The prognosis for moon colonization could appear optimistic but it surely’s grounded in actuality: We have now a course, a schedule and the pioneering minds required to begin our future on the moon. Importantly, we have now a renewed will to return.
Offered here’s a grand view of the long run, envisioning the moon as a scientific outpost, a deep area coaching facility, a vacationer vacation spot and, finally, the primary cease in humanity’s ascent deeper into our photo voltaic system.
Our first mission is to return.
After leaving the magnificent, desolate plains of the moon a half-century in the past, NASA is gearing as much as put people again on the floor by 2024. That mission, often called Artemis Three, will mark plenty of milestones in lunar exploration, together with placing the primary lady on the moon. Of the present crop of 12 feminine astronauts lively with NASA, one will plant her boot within the lunar regolith throughout Artemis Three.
On Earth, the triumphant return will likely be watched stay by greater than Three billion folks on TV, throughout the net and on their telephones. Not like Apollo 11, broadcast to the world in grainy black-and-white, the brand new mission takes benefit of recent digital camera expertise, giving viewers essentially the most spectacular take a look at the lunar floor but.
“Subsequent time we go to the moon can have full high-def, 3D pictures coming again, and we’ll be capable of obtain these pictures with no drawback in any respect,” says Glen Nagle, outreach lead on the Canberra Deep Area Communication Complicated.
It isn’t simply people returning to the moon, nonetheless, and NASA is not the one area company going there. China’s Chang’e program has already been wildly profitable and in the course of the 2020s it continues to land a number of robots throughout the moon earlier than extending this system to include human lunar exploration. By the tip of the last decade, the primary Chinese language astronauts are getting ready to make their method to the floor of the moon.

Attending to the moon continues to be an costly and tough course of, however we have grow to be somewhat higher at it. The Lunar Orbital Platform-Gateway, a world area station in orbit across the moon, begins development in 2022 and will likely be approaching completion by 2030. The eight-year mission has its detractors, however with the backing of a number of area companies, it goals to be a stepping stone for people to flee low Earth orbit and get into area. It consists of a collection of modules designed for habitation, experimentation and supplies a “spaceport” of kinds, the place spacecraft could be refueled and resupplied.
With the Gateway in orbit, our understanding of the moon and its sources dramatically will increase because the floor and subsurface are surveyed, probed and analyzed. Returning people to the moon is simply the beginning of a whole lot of scientific experiments centered on sustaining our presence there.
“I feel we’ll see the institution of analysis functionality. Initially, you will see robotic missions, which can make preliminary measurements, do some science in new areas, [and] discover issues just like the ice that we all know now could be on the lunar poles,” says James Carpenter from the European Area Company’s directorate of human and robotic exploration.
“After which over time, you will see this increase analysis functionality, primarily, with people tending that analysis infrastructure, so chances are you’ll go to one thing that appears a bit like Antarctica, with a sustained analysis functionality on the lunar floor.”
One of the essential short-term objectives is enhancing our information of the water ice situated on the lunar poles. Direct proof of this water ice was discovered inside affect craters in 2018 and our preliminary intrepid steps on the moon will deal with how we are able to use this water, sustainably, to assist our exploration efforts. Carpenter explains there’s plenty of work to do throughout this decade as a result of we do not know quite a bit concerning the distribution or accessibility of the water, solely that will probably be a crucial useful resource for extending our keep.
Nevertheless, science is not the one motive for heading to the moon.
“The moon is probably fairly an superior vacationer spot,” says Andy Weir, creator of sci-fi novel The Martian. Weir’s second novel, Artemis, imagines a moon colony funded primarily by tourism, with residents of Earth paying upward of $70,000 to go to the moon. “If there was a metropolis on the moon, that is the one place you possibly can go to take a look at Earth in its entirety, ,” he says.
Personal firms, like Virgin Galactic and Blue Origin, are more likely to begin shuttling the mega-rich into Earth orbit within the early 2020s. Nevertheless, Sarah Pearce, deputy director of astronomy and area science on the Commonwealth Scientific and Industrial Analysis Organisation, suggests it is likely to be a stretch to see moon tourism by the tip of the last decade.
“I completely assume we can have area tourism properly earlier than that, however will probably be suborbital,” she explains, pointing to Virgin and Blue Origin because the drivers of this new method to vacation. Nevertheless, it is Elon Musk’s plans that might start to show the moon into a beautiful — albeit costly — choice for lunar vacationers over the following 5 years. Musk and SpaceX plan to ferry Japanese billionaire Yusaku Maezawa and a handful of artists to the moon in 2023, aboard the corporate’s next-gen Starship rocket, for an undisclosed sum of cash. Musk has even urged Starship may get to the moon as early as 2021.
On the 60th anniversary of the Apollo 11 touchdown in 2029, non-public residents can have visited the moon, however we can have solely simply scratched the floor of what people can obtain there. Just like the 50th anniversary celebrations in 2019, the Apollo 11 milestone will likely be celebrated by a handful of extremely skilled scientists and astronauts inside an area station and by these making their means right down to the lunar poles. As we launch into the following decade — the 2030s — our focus shifts to sustaining our presence on lunar soil by making the most of the moon’s pure sources.
Lunar explorers — each man and machine — start to make the most of the moon’s sources to most impact early within the decade. On the floor and in orbit, astronauts are actually priming themselves for an onward journey deeper into the photo voltaic system and their first steps on one other planet altogether.
“The moon is the proving floor. Mars is the horizon purpose,” mentioned NASA administrator Jim Bridenstine in March 2019. Nevertheless, to succeed in that purpose, plenty of key technological advances should happen. Chief amongst them is harnessing the pure sources current on the moon to scale back the prices of off-Earth exploration. This course of is called in situ useful resource utilization, or ISRU, and it is important to increasing our capabilities on the moon. Scaling up ISRU won’t solely require a human contact, however growth of synthetic intelligence to autonomously work and mine lunar sources.
NASA’s Resolve rover would “discover, characterize and map ice and different substances in nearly completely shadowed areas.”

And the obvious useful resource on the craggy face of the moon is the mud and rock that litters the lunar soil. The positive lunar mud could be significantly nasty for human lungs however it’s wealthy in stuff we simply cannot discover as simply on Earth. It is ample in helium-Three, a proposed clear vitality supply, and its rocks include an essential mineral often called anorthite. Composed of a handful of notable components, anorthite could possibly be used for all times assist programs and development, forming the spine of a powerful lunar manufacturing business. Most significantly, the rocks are simply mendacity round in every single place.
“You need not mine, you need not dig tunnels, you need not do something like that,” explains Weir. “You simply must scoop them up off the bottom.”
Amassing and smelting anorthite offers us two key substances: oxygen and aluminum. One other ample lunar mineral, ilmenite, may be used to extract oxygen and would provide metals akin to titanium and iron. Harnessing the facility of the solar to energy equipment and mining tools will permit us to drag these worthwhile components from the very floor we stroll on with minimal disturbance to the pure surroundings.
Extracting oxygen on the moon is immensely useful as a result of people will nonetheless must breathe in 2040, but it surely additionally kinds a worthwhile element of rocket gas. Combining it with hydrogen extracted from water ice deposits discovered on the lunar poles supplies us with propellant, which makes the moon a really engaging spot to cease over as we head deeper into area.
“When you find yourself on the moon, you are many of the method to wherever, energetically,” says Carpenter, invoking a basic quote from science fiction creator Robert Heinlein. “So if we have now deposits of propellant on the moon, this may be very helpful.”
However there’s a draw back. As we start to go to the moon extra often, using an increasing number of sources, strain will mount for better oversight of human actions on the floor. As many new nations plant their flags within the soil for the primary time, our at present optimistic view of a peaceable, affluent moon devoid of nationalism is more likely to be challenged.
The Outer Area Treaty, which governs actions in area, doesn’t forestall exploitation of the moon’s ample sources. Michelle Hanlon, an area lawyer, factors out that a number of the flimsy definitions throughout the treaty are open to interpretation, complicating how a state could (or could not) be capable of declare possession over areas of the moon. Moreover, the Moon Treaty, designed to make sure actions on the moon and different celestial our bodies conform to worldwide legislation, shouldn’t be at present ratified by any of the main spacefaring nations. Neither treaty supplies safety for humanity’s most essential lunar archaeological areas: the six Apollo touchdown websites.
The positioning of humanity’s first off-Earth exploration: Will we be capable of protect these websites on the moon?
NASA
“The lunar touchdown websites are the final word heritage web site,” says Hanlon, who additionally based For All Moonkind, a nonprofit that seeks to protect area heritage websites. “No web site on Earth is that this pristine.”
“As people migrate into area and search to harness its ample sources, we have to work out a method to respect the rights and freedoms of all area actors.”
By 2040, worldwide agreements will designate the myriad websites of the Apollo landings as “Photo voltaic System Heritage Websites” — the primary of their variety. Tranquility Base, the situation of Armstrong and Aldrin’s first steps, is considered a sacred location, protected as stoically because the Pyramids of Giza or the Nice Wall of China are on Earth.
A harder proposition will likely be tips on how to reconcile our science targets with these tailor-made for exploration. If new websites on the moon, such because the lunar poles, do present us with some startling proof of different life within the photo voltaic system, we’ll be required to rethink our methods yet again.
Whereas area companies world wide will busy themselves with science and sustainability on the moon, Mars supplies one other problem altogether. Elon Musk’s SpaceX is aiming at 2022 for the corporate’s first mission to the purple planet, with human touchdown to happen in 2024. That appears an bold purpose at current. For SpaceX it requires profitable growth of Starship and plenty of yet-to-be-seen technological enhancements that, as an illustration, present a supply of gas on the floor of Mars.
It is cheap to suspect we can have planted our ft on Mars as the last decade involves an finish however we’ll nonetheless be mastering deep area journey. The moon is the most effective place we have now to study. We’ll have scooped up its rock, higher understood lunar geology and historical past, utilized its huge polar caps to produce us with water and rocket gas, and established a continually crewed base of operations.

The face of the moon is altering.
As people start to really colonize the floor, we’re now not guests, however absolutely fledged residents. Whole stations designed to maintain our presence have sprung up, and worldwide area companies now have their very own colonies: Russia’s development of a lunar base has been 15 years within the making, and China has assembled a village made up of “lunar palaces,” rows of 1,600-square-foot, self-sustaining cabins that astronauts will stay in 12 months spherical.
Satellites, like SpaceX’s not too long ago launched Starlink, depart streaks throughout the sky, obscuring our view of the universe.

The fixed occupation of the moon has allowed scientists to review area in a means not attainable on Earth. One of many moon’s unheralded sources is a transparent, silent sky, bereft of the chaotic noise of human communication. In 2019, Earth’s orbit is already filling with satellites, particles and tiny, highly effective cubesats continually beaming information again on the planet. New satellite tv for pc constellations have brought about grief for astronomers on Earth, however lunar orbit is unlikely to expertise the identical degree of congestion. That makes it an ideal spot from which to look out towards the universe.
“The far aspect of the moon has all the time been an fascinating suggestion to do a really delicate, low-frequency radio astronomy experiment,” says Ilana Feain, a radio astronomer and commercialization specialist at CSIRO in Australia. Within the 2040s, the primary lunar astronomers have settled in at a radio telescope on the far aspect of the moon. A set of flat antennas lie throughout a big swath of the lunar floor, giving us a moon’s-eye view of the cosmos for the primary time.
“There isn’t any ionosphere on the moon, so you do not have to fret about indicators being blocked, and since you’re not dealing with the Earth at any time, you additionally haven’t got to fret about all of the nasty interference that comes from humanity.”
Feain means that lunar radio astronomy might be able to unravel a number of the nice mysteries of the universe and probably even seek for the faint techno-signatures signifying the existence of clever life.
One other thriller, nearer to residence, is how lunar occupation impacts the human physique. We all know long-term stays in area can alter a slew of regular organic processes affecting our bones, coronary heart, mind and eyes.
“The area surroundings doesn’t provide circumstances for which people had been made,” says Jennifer Ngo-Anh, workforce chief of ESA’s science in area environments program.
Human our bodies advanced to stay below the fixed pressure of 1g of gravity, however as soon as we’re off Earth, that pressure is drastically diminished. On the floor of the moon, it is solely one-sixth as sturdy. Then there’s the problem of cosmic radiation, which we’re largely shielded from on Earth, continually bombarding us in area — and we’re unsure how damaging it is likely to be.
A part of the answer will likely be enhancing our area fits so that they’re extra versatile and supply better dexterity. With advances in AI and tender robotics, we’ll see a proliferation of smartsuits, simply eclipsing the intelligence of modern-day cellphones. With augmented actuality overlays constructed -in and self-healing skins, the fits will grow to be human-shaped assist habitats permitting for prolonged exploration on the lunar floor. However what of the layers of pores and skin and bone contained in the go well with?
Actually, one among our biggest challenges on the moon will likely be how we keep wholesome.
The Kelly brothers had been a part of a year-long research to evaluate how spaceflight impacts the human physique. Bear in mind: Mark Kelly has a wonderful mustache. Scott Kelly doesn’t. Word: This doesn’t make Mark the evil twin.

In 2019, NASA’s Twins Examine noticed how astronaut Scott Kelly’s physique modified compared to his earthbound twin Mark after 340 days in area. The analysis workforce confirmed that Scott’s gene expression modified and his DNA was broken throughout his keep in low Earth orbit, together with damaging modifications to his imaginative and prescient. It is exhausting to attract conclusions from the research group — it solely featured one topic — but it surely’s fairly apparent we’re not meant to be zipping across the Earth in large tin cans.
And people tin cans can grow to be fairly lonely. People spending prolonged durations of time on the moon will likely be among the many most remoted and confined in all of human historical past. Selecting the moon will present a test-bed for the results of that lonely existence, instructing us how considerably isolation impacts the psyche in area. Nevertheless, we have been researching these results at one among Earth’s most remoted areas: Antarctica.
“The French-Italian Concordia Station is one among solely three analysis stations on the Antarctic continent which are completely occupied all through the whole 12 months,” Ngo-Anh says. “A keep on Concordia station resembles quite a bit the circumstances that astronauts should face when they’re on long-duration exploration missions.”
Extra distant than the area station: Antarctica’s Concordia station.
ESA/IPEV/PNRA–A. Salam
With the closest neighbor to Concordia 600 kilometers (about 372 miles) to the north, the bottom is extra remoted than the ISS, explains Ngo-Anh. Crews on the station expertise 4 months of whole darkness from Could via August. In such excessive circumstances, the physique — together with the thoughts — does its finest to adapt, however researchers have seen confusion, irritability, melancholy, insomnia and even gentle trance states exhibited by these staying on the station. One crew member advised the BBC in 2012 that life modifications from “being in technicolor to black and white.”
Having spent 20 years residing on the moon by the tip of the 2040s, we’re portray a clearer image of what it means to stay in area. Our stations are fitted with centrifuges that permit scientists and astronauts to get their repair of synthetic gravity every day and we have grow to be higher at coping with isolation and confinement because of advances in communications and growth of recent augmented and digital actuality platforms. Sick of the darkish, barren panorama on the moon? That is OK — you possibly can slip off to a sunny shoreline in Malta as quickly as you strap on a headset.
The moon was new, barren, darkish and chilly lower than 80 years in the past. Now, as we hit 2050, it helps human beings all 12 months spherical in the identical means analysis stations in Antarctica do. Critically, the moon has grow to be the highest-fidelity analogue to recreate deep area exploration missions. The information we acquire main as much as the 80th and 90th anniversaries of Apollo 11 offers us each the instruments and abilities we have to survive on a very completely different planet: Mars.
Humanity’s first steps on the moon reverberate throughout the photo voltaic system. Our one large leap in 1969 has grow to be one colossal bounce by the point we have fun the 100th anniversary of Apollo 11, with the lunar touchdown centennial social gathering an interplanetary affair. People on the floor of the Earth, in orbit, on the moon and on the dusty, purple plains of Mars toast to the primary time people ever stepped foot exterior of planet Earth.
On this decade, journey between low Earth orbit and the Earth is so simple as reserving a flight from New York to London — and reusable rockets from firms like SpaceX and Blue Origin have dramatically diminished prices. Nevertheless, it is nonetheless prohibitively costly for many to journey a rocket to the moon. Just like the Antarctic, the lunar floor stays a spot that only some thousand get to go to annually, they usually’re principally scientists and researchers.
There is a grim certainty about residing on the moon that we should now confront, nonetheless: We’re additionally dying on the moon. Whether or not by error, malfunction or misunderstanding, and although each effort will likely be taken to stop it, the lunar floor will seemingly grow to be the primary celestial physique a human being dies on. Those that bravely tread on the moon, a whole lot of 1000’s of miles from residence, will come to relaxation there eternally. That, too, will likely be a brand new problem for humanity, which to this point has by no means needed to retrieve the our bodies of astronauts from area or a distant physique. Heads of state will little doubt put together speeches for such a tragedy, like Richard Nixon did earlier than Apollo 11.
Maybe essentially the most fascinating predictions concerning the 2060s is how the inevitable technological advances will reshape our societies and cultures. The European Area Company’s James Carpenter explains the financial affect of area exploration is “very vital,” noting that the entire cash we spend on area additionally will get spent on Earth. Already, Earth-based industries are presenting unique enterprise circumstances for lunar business primarily based on tweaking their established protocols and practices. The tweaks could possibly be so simple as offering communications to these on the moon or offering options to complicated issues akin to creating water-free methods to mine its subsurface or constructing clever machines that perform duties remotely and autonomously.
The social affect will lengthen even additional as an increasing number of people have an opportunity to look again on the Earth because it hangs, partially lit, in opposition to the black curtain of area. Astronauts on the ISS and in the course of the early exploration missions have reported a cognitive shift in consciousness, often called the overview impact, which happens if you lastly view the Earth in relation to the remainder of the universe. The fact sinks in: This fragile globe accommodates all human life that has ever existed. Will such a sight compel us to guard our residence? Or make us extra inclined to depart it?

And an even bigger query lingers: What’s going to we have now to guard by 2069? The planet is within the midst of a local weather disaster the likes of which we have now by no means seen, by which rising temperatures threaten lives, rising sea ranges threaten cities and rising ranges of extinction threaten the biodiversity on Earth.

Most of the scientists and researchers I spoke to had been reluctant to make any sweeping predictions about humanity’s future on the moon. “I actually hope that we have folks again on the moon inside a decade,” Pearce says, pointing to NASA’s Artemis missions and a rising worldwide curiosity in returning to the moon.
It is tough — possibly even loopy — to attempt to predict the way forward for the moon over the following 50 years, however there’s one unassailable reality concerning the human expertise: We have now an insatiable starvation to know and an unquenchable need to hunt out the reality of our universe. Carl Sagan, some of the revered astronomers of the 20th century, remarked initially of his acclaimed documentary collection Cosmos how the floor of Earth is merely the shore of an enormous cosmic ocean. By touchdown on the moon, he mentioned, people had waded out, ankle-deep, and located the water inviting.
100 years later, we’ll have realized to swim, treading additional into the unknown and watching the waters of the cosmic ocean rise as much as our waist.
All of it begins with the moon.
