Human Space Travel

It’s right to point out that space exploration is not solely a scientific endeavour. It’s odd to have to point that out. I do so because there are some purists who think that money should only be spent of space exploration if there’s a tangible scientific gain to be had. This thinking goes back to the agreement that public funds should only be spent of Earthy concerns. A glance at the extensive list of trouble that persist around the globe is one reason to focus on Terra firma rather than up at the heavens. That said, the choice is rarely simple.

Then there’s the accusation that exploration, of any kind, is intrinsically imperial. Powerful entities looking for sources of future dominance and wealth. This is not entirely wrong given humanity’s history of plundering resources from wherever they come. Minerals and trade routes being a couple of the primary sources of interest. A strong political will can be amassed to compete to be first to get a foothold on new territory. Despite all the above there’s something more complex going on.

The recent Artemis II space mission may not have been a great boost to humanity’s scientific knowledge. This adventurous lunar fly-by mission was more about proving technology than gathering an abundance of discoveries. Afterall, the far-side of the Moon can quite adequately be surveyed by automated spacecraft. Much as is being done by robotic machines on Mars.

I think there’s little doubt that 1st to 11th April 2026 will be recorded in the history books. If for no other reason that the gap between the Apollo space missions and Artemis. Like so many schoolboys in the 1960s, I watched those black and white TV images of men on the Moon, as they happened. I became an engineer. Would that have happened anyway? Probably, but I’m not discounting the inspirational impact of the Apollo missions.

[What would we ever do without the writings of the ancient Greeks and Romans. Certainly, naming new space missions would be a lot harder.]

Do we need crewed missions in future? Given the advances in automation and autonomy that have taken place in the last 50-years, so much can be achieved without the need for humans on-board a spacecraft. However, this is not a binary argument. There are, and always will be, the need to take human experience to the absolute limits. President Kennedy cited George Mallory for a reason to explores space, “Because it’s there,” he said.

The simple notion that humans should be constrained and confined to Terra firma runs contrary to our intrinsic nature. Although societies do become more risk adverse as they acquire the comforts of economic success, there’s still an appetite for exploration even if it entails great safety risks. The allure of being the first does not diminish.

Ideally, the combination of adventure and discovery go hand in hand. Space exploration is not just indulging the most adventurous amongst us. Thus, I go back to my proposition that there something more complex going on.

The ancient Greeks and Romans could help. For what is humanity’s destiny? Ad Astra has a meaning. Far more than the movie of that name. Not one of my favourite movies either.

There’s an inevitability that humanity will go to the stars. That is, if in the meantime wars or environmental degradation do not consume us. Exploration is part of a natural progression of intelligent life. It maybe (likely to be) happened elsewhere in the universe too.

Humanity’s Next Frontier Awaits

This April the first was marked by a moment that will go down in the history books. Tens of thousands of people who directed their efforts to building a new generation of spacecraft will see their labours rewarded. People with a vision that looks beyond the horizon have set in train a mission that will demonstrate that we are not confined to this rocky planet. Space – the final frontier. A vast frontier that’s there to be explored. Discoveries await.

By venturing beyond any humans in history, four brave astronauts represent us all. They started their journey in America, but when they look back all they will see is Earth. The dark of space with this lush globe brightly illuminated by our Sun. Ahead is a bright rocky sphere.

Not for one moment should we look upon this Moon-bound space mission as straightforward. There’s one thing that is absolute about the void of space. It’s a hostile environment for humans. Every system that is built into a spacecraft must work as intended. Contingencies need to be planned for every possibility.

This space mission is made possible because of partnerships. Europe[1] , US[2] and Canada working together for a common goal. What is known as the Artemis program aims to make the Moon accessible. To effectively shorten the distance between the Earth and its satellite.

There is a whole world benefit in moving from the Moon as a scientific curiosity to a place where humans can live and work. This is not a binary argument. We must solve our problems on Earth as well as exporting our environment.

Space exploration does help us see our fragile Earth in context. Everything beyond Earth shows no concern for our fate. In fact, it’s imperative that we gain as much knowledge as is possible about the near-Earth environment. A Moon base is a viable place to do just that.

My hope is that this remains a fundamentally civil enterprise. Such that the findings derived from the Moon’s exploration are for all humanity. It’s not a place to continue the conflicts that scare our home planet. I maybe idealistic. However, it’s for humanity to frame the rules that will apply on the Moon’s surface. Rules will be needed.

My hope is that this Moon mission goes smoothly and that everyone is returned safely back to Earth. That a new generation looks up at the Moon and sees it less distant. With the experience gained the next Moon mission should be able to go further.

From Daedalus to Artemis

Being in good company is always nice. That spirit of experimentation doesn’t suite everyone. Now, I find myself in company of a NASA astronaut and an 12th Century English Monk. All in one week.

I stumbled across the NASA App[1] last evening. I hadn’t reckoned at that being available on my smart Sony TV. There it was. So, it only seemed right to download it and check up on what’s going on with the current Artemis mission. Other News told of delays and troubles with the launch vehicle that’s to send astronauts to circle the Moon. Setbacks are common in space flight so that’s not an issue to be alarmed about.

[Whatever would we do without the Ancient Greeks. Artemis, Apollo, Mercury, Gemini[2]].

This is a fundamentally important space mission given that it’s the first-time humans will have ventured so far since the days of the Apollo missions. Sending four astronauts around Earth’s satellite is a hard task to undertake. It’s aimed at establishing a means to get to the Moon on a regular basis.

Apollo spacecraft did this journey when computers were relatively primitive machines. Artemis has the advantage of a technical capability that is many fold greater. The problem is that sheer complexity and society’s tolerance for safety risk has moved on since the 1960s.

Anyway, the tale told, in interview of one of the Artemis astronauts is one of jumping off a barn roof as a young lad. Constructing a homemade parachute and trying it out. Having that freedom of a life growing-up on a farm and that appetite for experimentation. I was thinking, been there, done that and lived to tell the tale. In my previous scribblings I’ve mentioned the large red Dutch hay barn that was part of my youth.

Back to the Greeks. It’s myth but there may have been an element of truth in it. A map of modern Greece makes it clear that the islands of Ikaria and Crete are separated by a great distance. So, suggesting that a father and son in ancient time flew from one to the other can’t be true. However, that doesn’t dismiss the possibility that the Greeks experimented with the possibility of human flight.

So, the myth goes, Daedalus was the design authority for a method of flying which does not come recommended. Strapping on wings made of wax and feathers is a 100% risky venture. Daedalus was, if a real person, an imaginative ancient inventor. An inspiration to others. In this century it’s best to interpret the famous myth of flight as one of experimentation in a way that is fully respectful of the risks involved.

Coincidentally, this week, more by accident than intention. It’s a long story. I visited the town of Malmsbury. Inspired by the story of Daedalus, Monk Eilmer of Malmesbury[3] has solid claim to be the first European to fly. It wasn’t an entirely successful flight, but it was a flight. In the 12th Century he leapt from a church tower with wings of his own invention and survived.

Monk Eilmer of Malmesbury did end up with broken legs and a place in history. It would be unwise to repeat his early experiment as an example of human flight. That is unless a crude glider was replaced by four rotors, electric motors, some electronics and a powerful battery.

I share the hazards of a technical ability. Luckily my youthful attempts at flying with a parachute made of black polythene sheeting from a red barn roof didn’t result in any broken bones. Good luck to all who fly. Especially those who travel the furthest.

The most important invention in your lifetime is…

A standout invention is one that is enduring. It’s celebrated. It shapes what comes next. It addresses an issue that’s been there for a long time. That just it – time.

I’m stretching the intent of the question a bit. Invitation doesn’t always have a single moment of realisation. Theory and experimentation come together to show promise. It’s latter that practical applications start to flow from that innovation. For me, the key invention is the beginnings of atomic time. The ability to measure time with precision.

Now, we know that past, present and future are the way we experience time. Not time itself. Having create clocks that gain or lose less no more than a second in billion years is an astonishing feat.

Today, a great deal of the infrastructure that surrounds us, and we hold in our hands, depends on precise time. Communication systems exploit it. We navigate using this asset. Society has been and will continue to be transformed.

Yet timekeeping systems have not reached their limit.

To the Moon

About £10. If it was good enough for the Apollo astronauts, it’s good enough for me.

“Fly me to the moon. Let me play among the stars”. Just imagine what that song, ringing out in the empty space between Earth and its satellite, would feel like.

Recorded in 1964 it was timed so well. The “We Choose to Go to the Moon” speech happened in 1962. The song is older than that, but I wonder if that was a reason for Frank Sinatra[1] taking it up? If this song doesn’t put a smile on your face – what will on Earth.

Exploring Space: A Journey

I haven’t got many of my childhood Ladybird books. One I have kept in good condition is “Exploring Space.” It’s got the characteristic illustrations and simple stories that are made to captivate. This book is the revised edition that must date from sometime after 1971[1]. The front cover has an illustration of a moon lander floating above the moon. It’s a picture that says – look what we can do, this is the tip of the iceberg. Such an optimistic outlook.

Most of my career has been in the aerospace business. More specifically civil aviation. For short while, I did get involved in building ground test equipment for satellite systems. Some of the people I worked with built the Giotto spacecraft in the UK. The mission was to study Halley’s Comet. This spacecraft, launched in 1985, took close-up images of the comet. It discovered organic material within the comet and proved that a spacecraft could cope with the harsh conditions of such a flyby. 

My interest in space, and the complexities of getting there has been with me for a long time. It’s the ultimate adventure. It also shows what can be done by international cooperation. Giotto was the European Space Agency (ESA) first deep-space mission.

Mention the word interplanetary and what comes to mind? For people of my age. The Carpenters’ version of the song “Calling Occupants of Interplanetary Craft”. It’s an eccentric, but successful 1970s pop song about talking to aliens. It’s a cry for help that is as relevant now as it was then. “Please come in peace and help us in our earthly problems.” If ever we humans could do with help from a more advanced civilization, it’s right now.

A sense of wonder about the heavens is as old as our human story. What’s up there? Could we live there? Are there others living there already?

I like the idea of an English bishop[2] in the 1630s. An early science fiction writer he imagined a flight into space in a craft pulled by a flock of wild swans. Ten to be precise. Since there are plenty of swans here in the English town of Newbury, I thought about investigating that idea. Maybe not.

Last evening, for the first time, I visited the British Interplanetary Society (BIS)[3] at Arthur C. Clarke House in London. Their HQ is in Lambeth. Can’t say I like that part of London at all. It’s a peculiar mix of sterile skyscrapers and spaces waiting to be re-developed. Old London has been pushed aside.

The BIS has a long history. It’s no fly by night organisation. Not as far back as the English bishop mentioned above, but more than 90-years extant. They have promoted thoughts and ideas that go way beyond past achievements. Trying to imagine what a future may look like if our capabilities and drive for exploration continue to advance here on earth. I think there’s always a need for that creative imagination to push the boundaries of what’s possible.

This week has been Space Week[4]. A week to highlight all things space. Back in 1999, the United Nations (UN) declared that World Space Week would be every year from 4 to 11 October. For this celebration, this year, the BIS had put on an evening event called: Living in Space: A World Space Week Special Panel.

I won’t say too much only that it was a fascinating evening. We were a small gathering full of questions. BIS had assembled a prestigious panel of experienced individuals. There wasn’t much in terms of the practicalities of living and working in space that didn’t get discussed.

I’m reminded that despite the hostility of the space environment for our biology, what we know is that all the materials of which the earth is made are there waiting for us. Constructing habitats, with the robotics we now have, isn’t just science fiction anymore.

Music to Dance Under the Moon

Flicking through the vinyl albums that no one wants there’s one I should have rescued this week. In a corner, charity shops usually have a pile of gifted vinyl records. I like to look for a hidden gem. Unfortunately, what’s left is the tatty and practically valueless disks. Versions of musicals that have fallen out of fashion, scratched classical concerts and embarrassing compilations.

It’s harvest time. Autumn is undeniable. A colourful carpet of leaves litters the pavements. Remarkably warm. Monday’s blue skies set of the spectacle of the trees display. When the October weather is like this there’s not much to complain about. Crisp walks through the dappled light as the low sun’s rays shine through the branches. Good to be alive.

Looking out of the window in the early morning it was as if it was a spooky daytime. In a monochrome light the outline of the tree line was like a cutout silhouette. Nothing could move without being seen. Grass glittered. Hedges stood like army ranks. All because of the intensity of the moonlight. Constant in the cool air.

The pop tune that entered my head was there for the taking but I’d left it to one side. This is a song that resonated from my boyhood. Some might cringe a bit. Let’s suspend judgement and let the 1970s be the 1970s. “Under the moon of love” is about as catchy as it gets. Showaddywaddy[1] dressed up in their brightly coloured exaggerated 1950s garb. They were not the only ones to do that for Top of the Pops. What’s memorable is the danceability of their pop classics. It makes me want to move. Don’t tell anybody. Sadly, my long hair has long gone.

It’s the time of the harvest moon. So, it’s a time for moon tunes. Not just any moon but the first supermoon of the year will grace the sky tonight, Tuesday 7th October. This bright full moon of 2025 will light up the nighttime. It will not have a musical accompaniment in my garden even if there’s a lot to choose from. The neighbours wouldn’t like it.

The best of the pile is Neil Young and his Harvest Moon[2]. 180 degrees from the Showaddywaddy pop effort. Neil scores top rating. It’s melodic, melancholy and memorable. Fantastic. Just right for a quite evening gazing at the moon overhead.

On a melodic theme the next one I’d recommend is from Nick Drake[3]. Again, it’s the 1970s that provides the music. It was a decade of variety, to say the least. Song writers were pushing the boat out and coming up with magical results.

And here’s another. Another to dance to in the moonlight. Moondance in fact. Van Morrison[4] this time. Perfect for an October night.

And if anyone has ever doubted the genius of Beethoven there’s the Moonlight Sonata.

The coming night will mark the start of a run of 3 supermoons. November and December will be graced with magical moons. I hope that’s an omen for good. Love and happiness.

International Collaboration in Space

It’s only taken 20,000 years for Homo sapiens to migrate to the American continent and then decided to industrialise the Moon. Just imagine what the next 20,000 years has in store.

Putting nuclear power on the Moon is a possible enabler for a future Moonbase. Considering the length of time it has taken since the last footsteps on the Moon, a Moonbase is long overdue. That said, going to a faraway place where there’s an abundance of solar energy potential it’s an interesting development that nuclear power is given a priority.

My view is that exploration beyond Earth is a matter for the whole of humanity. Going to the Moon should be an international endeavour. There’s good reason to cooperate when it comes to exploration. For a start space exploration is incredibly hard to do. Rockets explode with an unsettling degree of frequency.

Modern humans have gone from tens of thousands on one continent to what may top ten billion on Earth. It’s no wonder space, the final frontier, beckons. Trouble is we have evolved as specialist on this planet. Not well adapted to the space environment. If our wandering species is to venture into the void, we need to be mighty determined. This will be hard. The hardest effort ever made.

It would be absurd for individual nations to establish separate camps on the Moon. The space race is a concocted nonsense. More flag waving PR than serious sense. Why do I say this?

One: Demand on resources, to build, develop and maintain, a space presence is high. Sharing costs has benefits when planning for the long-term. Continuing costs can be volatile.

Two: In the event of the almost inevitable failures and setbacks, better to have partners to create different ways and means to recover or mount rescues in the worst-case scenarios.

Three: Partners can specialise. Not everyone has to do everything all the time. Afterall, that’s how our modern society came about in the first place.

Four: Cooperative planning means more gets done at the same time. Duplication and fragmentation of efforts don’t serve the great goal of exploration.

Five: Earth’s people are interconnected and interdependent. Even small Moon based colonies will inevitably be the same. Reliant on connections, locally as much as to a distant home.  

As a spin off, making exportation an international endeavour can bring us together on this divided planet too. 

Exploration and Innovation

Is there a human on the planet who has never seen the Moon? I guess, there must be a small number. The Earth’s satellite comes and goes from the night sky. Its constancy can’t be denied. Lighting the way when it’s full.

Accurate measurements say that the Moon is drifting away from us. The pace is nothing to be concerned about. It’s not going to become a free flying object careering across the universe. Space 1999[1] is pure fiction. Let’s face it we haven’t even got a working Moon Base here in 2025.

What motivated humans to go to the Moon in the 1960s? The simplest answer is the explorer’s quote: because it’s there. A quote that can be applied to any difficult journey that’s being taken for the first time. It implies a human longing to explore. An insatiable desire to go where no one has gone before. That’s nice, only it’s a partial story.

Technology accelerated in the post-war era as science and engineering built upon the discoveries and inventions that conflict drove. Then the promise of peace dissolved into the Cold War. Sides arranged in immoveable ideological opposition. The technological race was on. Intense competition drove the need to be display global superiority.

Potentially destructive forces were, for once, channeled into a civil project of enormous size. The Apollo missions. The aims and objectives of which were “civil” in nature, however the resulting innovations had universal applications. Companies that made fighter jets and missiles turned their hands to space vehicles. Early rockets were adaptations of intercontinental missiles.

1969’s moon landing put down a marker in history that will be talked of in a thousand years. Putting humans on the Moon for the first time is one of the ultimate firsts. That first “small step for man” may be as important as the first Homo sapiens stepping out of Africa. A signpost pointed to what was possible.

More than five decades have gone by. Instead of looking up to the heavens we now look down to our mobile phones. Rather than applying our intelligence to exploration we strive to make machines that can surpass us. Of course this is not a true characterisation. Exploration has merely taken a different a direction.

Will humans step into the final frontier again? Yes, but not as the number one priority. Plans to return to the Moon exist. It’s the intense competition that drove the Apollo missions that is missing. The advantage of being first to establish a working Moon Base is not so overwhelming. Even this base as a stepping stone to the planet Mars is viewed as a longer term ambition.

One advantage of this century over the last is the advances in automation and robotics that have become commonplace. Modern humans don’t need to do everything with our hands. Complex machines can do much of the work that needs to be done. Footsteps on another planet can wait a while.

Enough of us continue to be amazed and inspired by space exploration. The challenge is not to achieve one goal. It’s to achieve many.

POST: I watched Capricorn One, the 1970s movie about a fake Mars mission. It could do with a remake. In many ways it is easier to fake now than it was with film and colour televisions the size of washing machines.

Communication Prevents Disasters

It’s often forgotten that there’s a need to repeat messages. We are not creatures that retain everything we see and hear. There are exceptional people, it’s true, those who cram away facts and have an amazing level of recall. Often that’s my reaction to watching students leading teams on University Challenge[1]. How on earth do they know those obscure facts?

Most of us do not respond well to those who say, “Well, I told them once. I’m not going to tell them again.” That line is probably one of the most misguided utterances a teacher can make. Like it or not, this approach is part of our heritage. Past ages, when deference was expected, listening was mandatory, and misremembering was entirely the listener’s fault.

We’ve had a cultural shift. Our complex technological society doesn’t work in a command-and-control way. Too many disasters can be traced to miscommunications and misunderstanding. Now, the obligation exists on those delivering a message to go some way to ensure that it’s received with a degree of comprehension. That’s when repetition has a role to play.

One of the pillars of Safety Management Systems (SMS) is Safety Promotion. It’s the Cinderella of the aviation safety world.

Why do I say that? Experience for one. It’s much easier to get policy made and funding for the “hard” sciences like data acquisition, analysis and decision-making systems. These are often perceived as providing tangible results. Actionable recommendations that satisfy the need to be recognised as doing something. Even if that something is questionable.

Communication is key to averting disasters. It’s no good having pertinent information and failing to do anything with it, other than file it. The need to know is not a narrow one. Confined to a specialist few.

Let’s go back to 2003 and the Space Shuttle Columbia accident[2]. This craft was destroyed in a disaster that claimed the lives of its crew. The resulting investigation report is extremely compressive, if slightly overwhelming, but it has some key points to make.

To quote, “That silence was not merely a failure of safety, but a failure of the entire organization.” [Page 192]. In other words, the hidden concerns and internal machinations of an organisation can smother safety messages and led to failure. Since 2003, it’s sad to say that there are multiple occasions when what has been learned has been ignored. The impact has been devastating.

So, to shape the future let’s remember the Cinderella of the aviation safety. Discovering problems is not enough. It’s vital that practical solutions and good practice gets promoted. That needs to be done forcefully and repetitiously.
