What Is the Point of Going to the Moon Again?
On 14 December 1972, Gene Cernan, the mission commander for Apollo 17, stood at the foot of the lunar landing module and said, "…I accept man's last stride from the surface, back home for some time to come – but we believe not too long into the hereafter."
He was the twelfth, and last, person to walk on the Moon, and clearly anticipated a relatively prompt return. That was not to be, every bit ambitions – if not funding – turned towards Mars. No one has walked on the Moon since.

Now the tide is turning. After years of interest in the Reddish Planet, the scientific, astronautical and entrepreneurial community is uniting behind a push to return to the Moon, both to proceed the research that was started by the Apollo missions and to prepare for future exploration.
Nosotros speak to 5 leading voices from the worlds of astronomy, philosophy, scientific discipline and technology to understand why we should render to the Moon.
Prof Lewis Dartnell – Astrobiologist, Academy of Westminster, United kingdom of great britain and northern ireland
The only astrobiological reason that you need to justify a return to the Moon is that it preserves ancient rocks from the World that have been splashed up past large asteroid strikes. And here I want to tip my hat to Prof Ian Crawford, of the University of London, for these ideas.
The World is an active and dynamic place. That's important in the emergence of life and its long-term evolution over billions of years. Yet the planet'south dynamism poses a problem when y'all are trying to find the earliest traces of life on Earth, because most of the planet's crust has been destroyed by plate tectonics [the shifting and recycling of the Earth'south surface rocks].

The Moon, on the other hand, is a stable, static and fifty-fifty deadening place in the sense of active processes. If there were a mode to get aboriginal rocks from Earth up onto the Moon, they would stick effectually for a long time, as they wouldn't be eroded or destroyed by plate tectonics. This is where asteroid strikes come in. If chips of the Globe got diddled off our planet and up into infinite, the Moon would sweep upwardly that material and preserve it.
So it stands to reason that there are probably ancient World rocks on the Moon that could incorporate microfossils or chemical fossils that would tell us about the origin of life on Earth.
The problem is that information technology is going to be quite hard to find these flecks of Globe. You lot might kickoff looking for hydrated minerals, which are ubiquitous on Earth only very rare on the Moon.
Any material splashed up would be distributed randomly across the Moon but yous could look for places where that material has been preserved.
The main problem of preserving biosignatures in space is the cosmic radiation. These high-free energy particles travel at close to the speed of calorie-free, and are subversive when they hit cells of organic molecules. So nosotros might want to target ancient lava flows on the Moon that may have covered up any Earth rocks that were lying on the surface at the time, and are at present protecting them beneath several metres of rock.
There would be the consequence of mapping to identify and date the lava flows, and then sending a mission to drill on a lava menstruum of the correct historic period.
Information technology would be hard piece of work. Information technology would be similar looking for a needle in a haystack without the apply of a magnet. On the other paw, the pay-off would be enormous. You would be finding Earth rock that is far older than anything found on our planet. And so there is a lot to gain from doing this.
Naveen Jain – Co-founder and chairman, Moon Express
If I were to paraphrase President John F Kennedy, "We choose to go to the Moon, not because it is piece of cake but because information technology is smashing business."
When Moon Express lands on the Moon, we will become the start private visitor to practice so. That is quite symbolic of things to come. To me, the next set of superpowers are likely to be entrepreneurs, not nation states.
The time is now right to employ technology to solve the grand challenges facing humanity. I argue that landing on the Moon could potentially bring earth peace. We fight over land, water and free energy, yet all we have to do is expect up into space and at that place is an abundance of these things.
It is only a matter of time before we become hit by a massive asteroid. If we live only on Globe, then humans are going to become extinct like the dinosaurs. Wouldn't you prefer to have some entrepreneur creating an underlying infrastructure so that we can really become a multi-planet society?
Listen to brilliant podcasts nigh the Apollo Programme:

- Science Focus Podcast | The mindset behind the Moon landing – Richard Wiseman
- Radio Astronomy Podcast | Talking Apollo moonwalkers with writer Andrew Smith
- History Extra Podcast | The race to the moon with historian Kendrick Oliver
What we will exist doing is creating the underlying infrastructure of space. Nosotros think of ourselves as the iPhone of space. Back in 2008, Steve Jobs launched the iPhone and the App Store. Obviously he had a seriously good thought of what people could exercise with the device merely couldn't perchance take anticipated the success that both were spurred on to by certain killer apps.
Now that we have created this iPhone for the Moon with Moon Express, nosotros take to ask ourselves what is going to be its killer app. Will information technology be something that Moon Express volition create, or is it something that we'll permit other entrepreneurs to exercise? Information technology could be bringing stuff downward to Earth, or using stuff to create habitats on the Moon.
My gut reaction is that bringing lunar rocks to Earth could be the virtually beneficial job initially. We could disrupt the diamond industry. Diamonds were never the symbol of love until the 1950s. De Beers created a brilliant ad campaign to sell that idea. If yous're an entrepreneur against a monopoly you lot don't fight it, yous modify the game. So, we bring dorsum the Moon rock and nosotros alter the paradigm: it's non enough to give her a diamond, if y'all love her enough you requite her the Moon.
Prof David Rothery – Professor of planetary geosciences, Open Academy, UK
Lunar exploration has been going on fairly vigorously for 20 years, but it hasn't involved people since the terminal Apollo mission. Nosotros currently have a series of unmanned missions around the Moon, including NASA's GRAIL (Gravity Recovery And Interior Laboratory) and Prc'southward Chang'east four, which became the starting time mission to successfully land on and begin exploring the far side of the Moon in Jan 2019. So the unmanned exploration is happening but there's only and then much you can exercise remotely.
You do need to become people among the surface materials as well – both for seeing the geology at close quarters and for taking measurements that you can't take from orbit. Apollo left four seismometers on the Moon for recording moonquakes. They weren't vivid but it'south the only other planetary body that nosotros've got seismology for. The data the seismometers collected told us well-nigh the Moon's interior only they were turned off after a few years to save money.

- Small steps: How NASA prepared for the first moonwalk
- Wernher von Braun: Director of the Marshall Space Flying Center/Saturn V Chief Architect
- Ladies who launch: the women behind the Apollo Program
A few more seismometers on the lunar surface would requite the states groovy insight into the Moon'due south interiors. But you have to be on the surface to deploy them and so that y'all can couple them properly to the ground.
Too there are rut flow experiments. We don't know the rate at which the Moon'southward internal rut is leaking out towards the surface. They tried to measure information technology during the Apollo missions but information technology didn't piece of work. They had trouble getting a expert hole into the ground. So we're guessing at the lunar heat flow until we can become dorsum, drill a hole and insert some equipment. And you're probably going to need people to practice something that fiddly.
Getting equipment to work on the Moon is a challenge we accept yet to overcome. The lunar dust rises and falls with day and night considering of electric static charges, so you can get grit flecks into your mechanisms and that can lead to problems. Just if you've got people at that place you can overcome those problems. They tin deploy fresh equipment and drill holes.
They can also wander around making geological observations. The orange-coloured lunar soils were spotted by an astronaut from one of the afterward Apollo missions. He idea it was something rusty but it was orange beads from an explosive volcanic eruption. If you've got trained people at the location, they'll spot the unusual things.
The Mars rovers – impressive though they accept been – haven't gone as far as astronauts that drove the Moon buggies around. It's a lot more expensive to get people at that place, simply they become a lot more done.
I was a child when the Apollo missions happened and I thought it was the time to come, I thought that was what we were going to be doing: putting people in space. It was inspiration for me. There is a do good from only seeing people up in that location considering it inspires the side by side generation of scientists. I don't recall you tin can decouple that from the scientific facts that you are going to find out. Every bit well equally the mysteries that you're going to unravel, you're also going to be inspiring the next generation of scientists.
Gonzalo Munévar – Philosopher, Lawrence Technological University, Michigan
Philosophy has to do with agreement our relationship with the world. In that sense, it is inextricably bound to science. Information technology seems to me that the philosophical concern of this is what happens if we go to places like the Moon.
We can look at what has already happened. Past going to the Moon, with Apollo and other missions, we take come to understand better what the Earth is like. So knowledge of the planetary arrangement and of the cosmos gives us cognition of the Earth. Information technology is non just idle marvel; it is something that, in the long run, affects united states of america because it makes usa understand our place in the Universe, and once we understand the Universe – and this is the point of practically all knowledge – we can then interact with that globe meliorate.
For us, understanding what the Earth is like is extremely important considering the Earth has changed. To understand that, we demand to know what kind of planet Earth was when it formed and what kind of forces have acted upon it. One of the near of import objects that nosotros have to study is the Moon.

By going to the Moon merely a few times we accumulated an extraordinary amount of noesis nearly what the Earth was like because the Earth and Moon apparently formed together. Even if this is not the example, information technology is still important to find out how the Earth and the Moon came to be together like they are.
The lack of atmosphere and activity on the Moon means its surface has a permanent record of collisions with comets and asteroids [in the form of craters], of a size and number that we do not have on Earth. The Moon knows so much.
To understand the Earth is to understand the Earth as a planet, which ways to understand what planets are, how they formed, how they evolved and how they relate to the Sunday and then on. The Moon is so close to united states. So going back to information technology is going to help us improve our understanding of our place in the Universe.
Exploring with humans is a lot more than expensive and unsafe than doing it with machines but in the long run we accept to do it anyway. It also provides other benefits because humans are much more adaptable than robots.
Steve Squires, the person in charge of the Mars rovers, one time said that he was very pleased with everything 1 of them had washed in the previous half-dozen months. But he besides pointed out that an astronaut could take done it all in a unmarried day.
It is bang-up that we have those machines, merely somewhen we need to be out there. I also think it is good to have adventures as a species so that more than people tin can be inspired by them and participate in their own.
Going to the Moon the beginning time effectually was so heady. Going back volition give the states the opportunity to go to other, more exciting places."
Commander Chris Hadfield – Astronaut, starting time Canadian to walk in space
Exploration is what teaches us things. It allows united states of america to make educated and informed decisions. If we never explore and so we cannot better and expand. Exploration is key to human nature. It is why we learn to walk before we larn to talk, considering nosotros have to explore to become well-formed man beings. And we have to accept exploration equally part of our society in order to be a well-formed gild.
There are so many precedents in history. I look at the businessmen of England in 1496 who were hesitating about what to practise in the wake of Columbus'southward discovery of America, "Well, okay he's discovered a new world, but should we do anything? Is there a quick buck to be made?"
But then a few far-sighted people in Bristol and a few in London said, "I call up exploration is going to lead to expert things. Information technology is going to have a while to get whatsoever money back but let'southward fund John Cabot." And Cabot's 1496 voyage was a consummate bust. Cabot launched out of Bristol in ane ship and didn't know what he was doing. But he learned a lot.
He came back, set out again in 1497 and and then discovered Newfoundland. He opened Due north America to England and began the corking English exploration over the side by side 300 years.
A lot of the world is uninhabitable without technology. But once you develop the right sort of technology, and so living in those places can take enormously valuable consequences for humankind. The real question is at what point does our technology become avant-garde plenty to make exploration economically viable? How much can be done by sensor equipment alone and how do we decide when people should go?
We tin can stick a weather station in Antarctica and it volition tell us the air temperature and the windspeed. But that is such a tiny piece of the information that we need to know near Antarctica. Most of the data needs to be inquisitively pursued and robots are terrible at doing that.
Then should nosotros abdicate lunar exploration for Martian exploration? They're both largely unknown. The real question is how do we not blow it? How do we not make fatal mistakes? Nosotros're going to get it wrong. On my three visits to the International Space Station, things went wrong all the fourth dimension. Y'all would have a difficult time counting the number of times that we needed to exist saved by bringing replacement equipment up from Earth.
If nosotros go to Mars for a half dozen-month voyage, so we are basically trapped in our own ignorance. It could end up being like the Franklin expedition, where you think y'all know what you're doing but yous inadvertently kill everybody. Nosotros accept to recognise that failure is a large, large part of success, and then y'all take to give yourself the opportunity to neglect without destroying the entire effort that you are trying to accomplish.
