It looks like we could cryo-sleep for the three month journey to Mars, but what about a twenty year voyage to the stars? That is going to require some major advances in medicine and equipment.         

So, we need to consider the medical and equipment requirements for an extended cryo-hibernation at say 5 degrees Celsius. This post will focus on medical issues.

The bodies’ metabolism must be slowed to a minimum ‘ticking over’ state whilst maintaining oxygen and blood flow to all vital organs and tissues albeit at a very low rate. This will need some very clever genetically modified DNA or stem cell technology by the end of this century – we certainly don’t have it now.

But let us get Zec to describe this….

‘It is not possible to freeze someone and then thaw them out in some years’ time – the body is 65-75% water and when that turns to ice it expands – think of the damage to delicate nerve ends, capillaries. If you cool someone down, they start shivering in an attempt to generate heat and if they can’t generate enough they die of hypothermia. The key to cryo – hibernation was to cool the body very slowly and at the same time to slow the body functions so that they required very little heat to maintain life. The breakthrough in animal testing 30 years ago (around the turn of the 22nd century) was the use of new strains of genetically engineered DNA which were introduced into the body as it cooled. These controlled the slowdown of body functions, pulse, brain activity etc. and through an exothermic reaction produced minute amounts of heat right at the key points of activity. Provided that the cooling and warming periods were long enough, the infused DNA balanced the bodily rates and the amount of heat required.’

Thus the process was proved first on animals that were successfully recovered after periods of up to 5 years cryo-hibernation. They were in very good health and, surprisingly, showed no deterioration in tissue quality. They appeared not to have aged!

Proving the process on animals was a major breakthrough but how do you entice volunteers to gain confidence that cryo-hibernation works for humans and for periods of up to 20 years?

The answer may surprise you, so perhaps you would like to take a 20 year cryo-sleep to the star Seren and wake up at Cloud Planet to discover life elsewhere. But your journey through time and space is only just beginning.

This is a relatively short duration but the principles and problems to solve are the same. Let’s now consider getting to our nearest star.

A journey to a star would mean a minimum of 20 years in the confinement of a spaceship – not impossible but a physical and mental strain for the crew – would they arrive in the right frame of mind to tackle the rigours of a new environment. Also they would be at least 20 years older, so experienced astronauts in their 30’s would already be ‘old’ on arrival. Maybe our crew would comprise of families with babies who would be young adults at the end of the journey. But this scenario is more likely for colonisation far ahead in the future.

So some form of hibernation, a method of protracted sleep, is almost certainly a must for future travel to our nearest stars. The term that springs to most people’s minds is cryo-hibernation [cryo meaning cold] but let us immediately dismiss the myth that you can freeze the human body and thaw back to life years later. Our bodies are 65% water and when that freezes it expands because ice has a lower density. The damage to sensitive cells and membranes would be traumatic. It’s a great process for preserving meats, fish etc in our freezers but in no way addresses human hibernation. 

A cryo process is almost certainly the way forward as we have to slow down dramatically the bodies’ metabolism whilst maintaining a supply of oxygen to every vital organ. A hibernation temperature in the range +10 degrees Celsius to -5 degrees would be required but for the lower temperatures some form of antifreeze would have to be injected into the bloodstream which could cause complications. I consider that +5 degrees Celsius would be optimum to operate a minimal metabolism whilst maintaining tissue integrity. 

There are many other issues to consider. When you wake in the morning you often feel stiff and can hardly get your eyes open! How would we cope after 20 years sleep?

I will discuss these issues in future posts and propose the technology and equipment for successful hibernation but if you want to pre-empt this then…. 

….board my starship in 2150 and sleep for 20 years when you will arrive at the star Seren, 10 light years away. Follow the link below. 





That was six years ago – it would be a huge ship and require an enormous quantity of fuel. But the principle is sound. In the vacuum of space you can continuously accelerate and ultimately approach a significant fraction of the speed of light.

Now there are serious plans to send a spacecraft to the stars! But on a much smaller scale, but the principle is the same.

Not big enough to take astronauts, but could the principle be scaled up?

For now let’s look at ion propulsion in more detail.

Let us imagine a journey to a star 10 light years away. We start from Mars orbit and outside the planet’s gravitational pull and use advanced rocket technology to reach Jupiter. This is a journey of 555 million kilometres [km] taking 7-8 months at 100,000 km per hour. [Approx. estimate of future capability]

We use the immense mass of Jupiter to attract and accelerate our craft onto a collision course [initially] and at the critical moment re-fire the advanced rockets to sling our spaceship around the gas giant and onto its new trajectory and new speed of 1 million km/hour.

Now we start the nuclear reactor, the only power plant capable of sustaining thrust over a 20 year journey [unless we discover something remarkable during the next 100 years]. The heat output from this reactor would be used to power a new type of drive capable of pushing our craft towards light speed. I will describe one concept which has been around for decades, surprisingly – the ion drive.

Here a stream of positively charged hydrogen ions [H+] is ejected at high speed from the rear of the object being propelled. The thrust is small but in the vacuum of space even a large object can be manoeuvred and accelerated provided you have enough thrusters. The ion drive of a starship is likely to be 50-80 metres in diameter and each of the thrusters say 5 cm round. You could get over 2 million thrusters in this drive [clustered around the advanced rockets] all contributing their power from the emitting stream of hydrogen ions.

By providing constant sufficient acceleration you would design to accelerate from 0.001c to 0.5c in 1 year [c = speed of light].

Thus our journey to a star 10 light years away would be approximately 23 years – 2 years to accelerate, 20 to get there and 1 year to slow down to a manageable speed to orbit around a target planet of our destination star.

 I’m sure the mathematicians among you can calculate the acceleration required and the typical thrust needed from each tube – can we achieve this in 150 years time?


I think we can and in 2150 my starship leaves Mars for the star Seren, 10 light years away. You may wish to watch the event in 1972 that sparked my story.


Read all about it in my sci-fi trilogy – Quest of the Dicepterons.  Follow the link below.




According to our laws of physics the answer is no. But the question for space travellers is how near the speed of light [c] can we get?

Light travels at 300,000 [approx] kilometres per second [186,000 miles per second]. When we look at our sun, not directly of course, we are seeing it as it was 8 minutes and 19 seconds ago. That is the time for light to travel 150 million kilometres [93 million miles]. 

Stars and galaxies are so far away that we express their distances in light years – the distance light travels in 1 year – 10 trillion kilometres [approx] – an unimaginable distance. 

Thus our nearest star is 4.2 light years away, our nearest galaxy 25,000 light years away and the Andromeda galaxy is a staggering 2.5 million light years away. 

For man only stars up to 10 light years away are potentially reachable. But to do this we need to travel at a significant fraction of the speed of light, say between 0.1 and 0.5c and this would equate to a journey time of 100 and 20 years respectively. 

In my view a journey time between 20 and 40 years is the optimum that human beings could tolerate – assuming we can crack hibernation [which I’ll talk about in a later Blog]. Therefore we would need to develop technology to propel a starship at between a quarter and half the speed of light. But can we do this? 

I will discuss the technology for achieving these speeds in my next Blog – but you might like to see how I achieve a journey to a star 10 light years away in my sci-fi trilogy – Quest of the Dicepterons.

The answer to my basic question is no, but a Dicepteron can! 






Some time in the very distant future we will have to colonise other planets in this solar system or at nearby stars. Our planet will become totally over-populated. But before then we might destroy it, either environmentally or through warfare. Further, we could be impacted by an asteroid causing a life extinction similar to the dinosaurs. Finally we could be invaded by an alien force – after all we have sent probes to the stars with our address on them!!


There are a number of milestones and challenges for mankind if we are to contemplate travelling to our nearest stars, 5-20 light years away. 

We must first establish a large moon-base towards mid/end of this century. This is feasible because we have discovered vast amounts of ice at the poles giving us water to drink, oxygen to breathe and hydrogen for power.  Structurally, moon-base would look like a huge Eden Project with specially designed plastic interlocking blocks to resist the vacuum.

Then in the early 22nd century we would have a base on Mars. This would be the nerve centre for a star mission and a suitable starship would be constructed in weightless orbit around the planet. Our mission would launch from here and use the huge gravitational pull of Jupiter to accelerate our craft. 

Now there are 3 key technical challenges for us to solve over the next century to make a mission lasting 20 years feasible. Firstly, we have to be able to travel at a significant fraction of the speed of light and secondly we have to develop technology for extended human hibernation by cryo or other techniques. Thirdly, and absolutely vital, we must develop artificial intelligence – computers so powerful and reliable that we can trust them to look after a starship with its precious cargo of hibernating humans throughout a 20 year voyage. I will talk in more detail about each of these in my next few posts. 


To answer my question – I think in about 150 year’s time but I would be fascinated to hear your views. 

 I have visualised such a journey to the stars in my scifi trilogy – The Quest of the Dicepterons – a fast moving adventure through space and time. Here I have imagined life elsewhere in the Universe, but I have also asked the question – “What if there is something else out there?” And we go and wake it up!

Pioneer 10 blasted into space from Cape Canaveral on March 2nd 1972 on top of an Atlas-Centaur rocket. Its primary mission was to photograph Jupiter but in early 1973 it became the first spacecraft to traverse the asteroid belt. Imaging of Jupiter began late 1973 and the closest approach was 132,252 km in December 1973.

There were two very unique aspects of this mission. This would be the first manmade object to leave our solar system and travel forever towards the stars and secondly a gold plaque – see picture below – was bolted to the spacecraft.762px-Pioneer10-plaque_tilt

The plaque depicts a man and woman and  shows the silhouette of the Pioneer craft. Further, there is information on our location in the galaxy and data depicting scientific values of key parameters on Earth. Back then I wondered if this plaque would ever be seen again and the grains of a story formed in my mind. But it would be 45 years before I wrote  and published the scifi trilogy – Quest of the Dicepterons!


‘Pioneer 10 spacecraft sends last signal – after more than 30 years, it appears that the venerable Pioneer 10 spacecraft has sent its last signal to Earth. Pioneer’s last, very weak signal was received on 23rd January 2003. NASA engineers report that Pioneer 10’s radioisotope power source has decayed and it may not have enough power to send further transmissions to Earth.’

‘And now,’ continued the NASA spokesman, ‘Pioneer 10 is the most distant manmade object at over 16 billion kilometres from Earth. Pioneer 10 will now continue to coast silently as a ghost ship through deep space into interstellar space heading generally for the red star Aldebaran in Taurus the Bull – a mere 68 light years away.’ 


Pioneer 10 is today [29/12/2017] approximately 17.8 billion kilometres from Earth in the direction of Taurus and the star Beta Tau. It is not now the most distant manmade object as it has been overtaken by Voyager 1 at 17.9 billion kilometres.

The location of Pioneer 10 is estimated by extrapolation of its last known signal in 2003, so it may not be where NASA thinks it is!

What if something caused it to change course by 90 degrees and accelerate to rendezvous with Cloud Planet 132 years later. Perhaps you might propose how this could happen or if you want to find out read – Quest of the Dicepterons.    

                     IMAGINE LIFE ELSEWHERE?                         







During the past 20 posts I have tried to take you, the reader, through a technical journey of feasibility of space travel to the stars. I believe this will be possible by the mid 22nd century and that the necessary technologies will have been developed by then.

But why go to the stars? The simple answer is because they are there! Mankind has always strived to conquer the four corners of the Earth, has visited the Moon and will in the next few decades land on Mars.

But ultimately we may have to find another habitable planet. Look at the damage we are doing to our own ‘home’ because we are not taking the environmental issues seriously. Look at the population explosion and the many factions on this planet that are focussed on its destruction. I fear for the future of our world during the next couple of centuries. hs-2009-25-e-web

But the big question is still – is there life elsewhere? – And I am utterly convinced there is. I am sure we will soon discover evidence in our own solar system of relatively simple life-forms that existed [on Mars] or may exist now in the sub-surface oceans of Titan, Saturn’s moon. But what about life as we see it all around us? There could be a billion Earth-like planets in the Milky Way galaxy and there are billions of galaxies in the Universe. I have shown how the building blocks for life have been formed in the furnaces of dying stars and then flung to all parts of the cosmos during Supernovae.

In pure numbers terms, life must have evolved elsewhere – but what would it look like? If there had not been an asteroid collision 66 million years ago on Earth then this blog might be being written by a highly intelligent dinosaur! 

In our humanoid form we have evolved over the last 200,000 years but look what we have done in the last 200 years and where we might be in a further couple of centuries. But our timescale is minute compared to the age of the Universe – what if, somewhere, intelligent ‘life’ has evolved for millions or even hundreds of millions of years? How sophisticated might that be! Ghostscript 24 bit color image dump Ghostscript 24 bit color image dump

I have imagined how life, similar to our own, might have evolved at a nearby star. I have also ‘imagined the unimaginable’ – what if something has evolved for hundreds of millions of years – what might that be capable of? This is the basis for my trilogy – Quest of the Dicepterons – and the first two volumes – The Blue People of Cloud Planet and Disaster Earth set the scene for an amazing journey of discovery. Volume 3 – The Quanoxy Zeric Galaxy is currently being written.
