Martian Salad Bar

As befits a cafe on Mars, here's a post about food.

Astronauts and Marstronauts who are away from sources of Earth-grown food may subsist on dehydrated food, packaged meals and so on, but as the engineer involved in the following video (see link below) points out, the sensory experience of eating real food adds a huge amount to our lives. We take it for granted, but travellers to Mars will probably start longing for something fresh after a few weeks or months. A graduate team at the University of Colorado have been developing a kind of automated plant grower and a robot plant-tender. Don't view this unless you like interesting things.

Meet the Gardening Robot

If such devices are to be used on Mars, in the initial stages of a colony, I would want to ask:

- Does the complexity of the electronics and mechanics in SPOT and ROGR justify the potential gain to the colony? The more complex things are, the harder they are to fix. Many spare parts would be required. Couldn't the colonists simply aim to bring or make their own soil, use some basic temperature & humidity data loggers, and hand-tend their gardens?

Beyond that, agriculture is not my speciality, but I'm sure that researchers such as those in the excellent video have been thinking through the details.

But as soon as they've worked out the details and are harvesting their first crop of Martian chili peppers, I'd like to reserve one kilo for use at the Red Planet Cafe.

Travelling to orbit by BALLOON?

When you first hear this one, you may be excused for thinking, 'No way! This is a hoax!'

But it's based solidly on real physics, and has absorbed the combined efforts of some serious engineers with degrees and all that.

It's called: Airship-To-Orbit.

Yes indeed. There is a real R&D company called JP Aerospace, founded by John Marchel Powell, that's totally committed to developing a non-rigid, lighter-than-air method of reaching low Earth orbit. And the crazy thing is that it makes perfect sense. Not only that, but it leaves me wondering why people like NASA or ESA haven't pumped a ton of money into it and made it work a whole lot quicker.

They may have their reasons. Read on.

JPA's plan is a three-stage process. First, a U-shaped high-altitude airship carries a crew of 3 up to 140,000 feet (that's well over 40km) where it docks with a 'Dark Sky Station'. It has this misleadingly sinister name because, well, the sky's dark up there. You're almost in space. Then from the Sky Station, an Ascender vehicle slowly powers up into orbit using a hybrid propulsion system which they're still developing. This Ascender vehicle is part-airship, and will measure maybe 6,000 feet (1800m) in length. That's over a mile! But it should be feasible, since this craft never touches the ground and operates well above the most turbulent layers of the atmosphere.

The problems? Well, how ever you get up out of the atmosphere, in order to achieve orbital velocity your vehicle must accelerate. This means energy must be expended, so you need fuel and an efficient propulsion system. How much energy is being saved by the use of airships? How much cheaper will the whole system prove to be?

One thing is undeniable, I think: ATO does look to be the safest way to reach space that's yet been proposed. Airships comprise a large number of gas cells. If a few are punctured, well, that's unfortunate, but it's not a disaster. The worst that will happen is that the airship simply has to float back down to Earth sooner than expected. No explosions, no sudden death.

I have a sinking feeling, though, that the main reason this approach hasn't received a huge swell of investment from aerospace companies is that it could prove to be too cheap! All those lucrative contracts for building big rockets... think about it.

Prepare for take-off?

I enjoy keeping up with the latest in space technology, but it seems I've been sleeping at the wheel. Someone's been inventing the future and I missed it.

An English inventor, Roger Shawyer, has been developing a microwave-powered thruster which uses absolutely no propellant!

Voices in the scientific community are expressing doubts and questions - along the lines of 'How can this possibly be true?' This is because, as we have understood the universe since the time of Sir Isaac Newton, if something pushes one way, there must be something pushing the other way. In a rocket motor, for example, tons of burning fuel shoot out the back which pushes the rocket in the opposite direction. Ion thrusters in satellites use electric fields to push ionised gas and move the satellite. But in this new device, nothing moves! Just microwaves. And microwaves have no mass.

Roger Shawyer proposes that the microwave radiation pressure difference inside the tapered chamber produces the thrust. The Chinese scientists who have both verified Shawyer's results have a different way of explaining it, and when NASA repeated the experiment recently they declined to propose a theoretical explanation.

Honestly, I'm fascinated. Will this prove to be another let-down, like cold fusion? Or will this be the 'dawning of a new age in the history of space travel', in the style of some of the recent journalism? Time will tell.

What could this lead to, if it's true? Certainly it might be put to good use in satellite station-keeping - maintaining a satellite's precise orbit against the slight but constant drag of the outer fringe of Earth's atmosphere.

If it can work efficiently on a large scale, in a vacuum, it might prove practical to power interplanetary probes and crewed craft on missions to Mars and elsewhere. If mission planners are suddenly told 'You don't need to take fuel anymore', everything will change. The need for fuel to accelerate and decelerate, to change orbits, is the big limitation on all space missions.

The force produced by this microwave drive looks small so far, but it can be maintained for as long as there's electrical power to generate it. So use nuclear power, perhaps, or lots of solar power, and a spacecraft could accelerate gradually, steadily, over a long period, to build up a truly impressive speed. The transit time to Mars, for example, might be reduced to weeks instead of months.

The eventual result, though, will be closer to home for me: I think that science fiction writers will have to change gears! Usually a writer has to 'invent' a space drive like this to allow easier travel to the planets, and eventually the stars, and it's tricky to make it believable. Perhaps, if there's a real space drive in use, it will make our new microwave-powered spaceships look realistic. Perhaps we'll still be inventing the next generation of drives. What next? Bio-fuel starships?

Martian Survival Classes

It doesn't take much research into the human and technical elements of colonising Mars to realise that huge numbers of people across the world are keen to see it happen. Many of them are using online forums to pool very practical ideas. 

What are the basic technologies that will keep colonists alive?

First of all is oxygen. The very thin atmosphere of Mars is mostly carbon dioxide. Water can be electrolysed into oxygen and hydrogen. So how will they find enough water?

- By digging it up! The loose Martian dirt, or regolith, contains a varying amount of water ice. Heat the regolith and collect the water vapour.
- By reacting the carbon dioxide in the Martian atmosphere with hydrogen to make water and methane. The latter is useful as fuel for rockets and generators. But the need for a stock of hydrogen may make this impractical for long-term use.
- By 'adsorbtion' into a special kind of rock called zeolite. Zeolite is a range of minerals known to be good 'molecular sieves'. One of these has a certain atomic structure which allows water molecules to enter, but keeps out the larger carbon dioxide molecules. So it just sits there and soaks up water from the atmosphere.

How efficient is zeolite? According to a NASA fact sheet the atmosphere is 210 parts per million of water by volume. So to squeeze one litre of water vapour from the air, you'd have to pump about 5 cubic metres of Martian air through the zeolite. And when that water vapour condenses into liquid, it only makes about 1ml of water! (It's actually a lot less, because the density of water vapour would be very low at Mars's very low atmospheric pressure.) So you'd need a lot more than 5,000 cubic metres of air to make a liquid litre. Then again, that tiny amount of water vapour in the atmosphere will vary by season and location. A zeolite unit with an air pump may become standard survival gear aboard crewed Mars rovers.

All this is like continually planning a vacation that never comes. It will be intriguing to see how the first Mars pioneers solve their problems.

Changing The Sign

Just a quick change to this virtual meeting place - A café is more suited to customers of all ages than is a cocktail bar. Those customers chasing harder drinks please get back in your Mars rovers and drive east-north-east about 5 kilometres, where you will find 'Craig's Crater'. It's a friendly place, but beware the bar snacks.

ISS Astronaut Rediscovers Ancient Wisdom?

So I got last-minute tickets to a talk by Chris Hadfield at the local auditorium.

The matinee show was for school children, as shown above. Colonel Hadfield began his quest to become an astronaut at the age of nine, after watching Neil Armstrong and Buzz Aldrin land on the moon in 1969. I have dim, black-and-white memories of that, too, but I was only three. He is a great communicator, eager to pass on what he has learned and experienced to inspire the younger generation.

He weaved one topic into the next, stitching them with some great stories - stories from 400 kilometres straight up, during his missions aboard the space shuttles and the International Space Station. If you want to get a flavour, look here on YouTube. There's an amusing site devoted mostly to his book, An Astronaut's Guide To Life On Earth.

What did he have to say that makes any sense to us mere Earthlings? Quite a lot. Here are the headlines, each of which need a great deal of unpacking and serious thought: 
  • Head for a big goal and live in the light of it
  • And at the same time enjoy what you're doing every day
  • Train hard to become competent
  • Prepare in detail for what could go wrong 
From his book, I also found this surprising point (surprising coming from an astronaut): 
  • Aim to start off as a zero- serving others - don't be arrogant. Be a learner. A good team player can't afford a big ego.
Chris Hadfield believes that a good communicator uses art to affect people deeply with the message.
I've heard that last one before, phrased differently. Sounds like ... Sounds a lot like what you'll find in an old, old book that I read quite often. Chris Hadfield doesn't speak about religious faith or spirituality, but wisdom is still wisdom wherever it comes from.

I wonder how Mars One trainees will become this seasoned and wise in just five to ten years of training. I wonder how Elon Musk will fuse these realities into his plans for SpaceX and the colonisation of Mars. It took Chris Hadfield about 21 years of experience as an astronaut to discover all that. You can read wisdom in a book but it takes the ups and downs of life to become wise, often learning from mistakes. From making the right decisions. Like... right now. Should I just take another coffee, another chocolate? Should you play more World of Warcraft or get back to your studies, your work? Choice of breakfast cereal, choice of college program. The passion with which I want to reach my goal feeds power into my ability to make the right choices each step of the way.

Aiming for a great goal does give depth to your life. The greater the goal, the more inspiring, but the easier to become disillusioned if things don't go as we'd hoped. For about ten years of my life I determined to learn Arabic. Not only would I be able to speak and read Arabic, I decided near the outset, but I would learn it well enough to be able to write poetry in that noble language! Actually it was the desire to be able to communicate with ordinary people that drove me onwards as the years went by, and I never did become much of an oriental poet. That's OK.

I  hope any would-be astronauts and marstronauts happening to read this will plot a course towards a noble, realistic and enduring vision to power them through the many years of preparations. Train to be competent, prepare for every possible disaster, keep your ego on a tight leash, commit yourself to your team-mates' success, and have a great time while you're doing it all!

Japan's Vision To Reach The Red Planet

Great that the Japanese government is getting on board the vision to explore and settle Mars. Here's an article about that.

And here's a picture of them doing it!

A Real Mars Person

Mars One has narrowed down to 705 marstronaut candidates from its olympic-sized pool of over 300,000. I was looking at a few of the 705's "Pick Me!" one-minute videos and came across one named Stephen, a Canadian living in Toronto. (Why does he want to live on Mars? I've just spent 3 days in Toronto and I fully sympathise.)

This candidate's refreshing. It felt like I almost knew him after his minute was up - I've met someone rather like him, I think, but he had an East London accent, listened to Tom Petty and claimed to be joining an expedition up Mount Everest.

Back to Stephen. Rather than your typical 30-to-40-year-old PhD-scientist-mechanic space fan, he's a world explorer. And he has the appearance of someone who's lived life fully, in every imaginable climate. He claims to have visited 160 countries. How can he possibly keep count? He shows pics of himself  drinking tea (spot the spoon in the tin mug) on a Sahara trek,
chilling out in Antarctica and doing some rescue diving. The line that made me smile, though, was near the end of his presentation: "I've seen the planet Earth. It's time to move on." He looks like just the kind of laid-back survival expert who would thrive on another planet. Good luck, Stephen!

Mars People

I think this could become a key 21st century question: What kind of people will thrive in a colony on another planet?

More particularly, is there a mix of personalities that will lead to a viable new society? From reading the opinions online and in print - and remember that in this field even the experts have never really done it before - most voices talk about the importance of team players, highly motivated and multi-talented people who can put their hand to almost anything and not fall apart under intense pressure.
Artist's concept of the initial Mars One base. Note: there's
plenty of equipment that could go wrong here. Who's going to
stay calm enough to fix it? (pic: Mars One)
Mars One: Good luck. I hope you find plenty of them!

If you listen to enough of the talks given by Bas Lansdorp, the founder of Mars One, you'll eventually hear him say that yes, he grew up dreaming of going to live on Mars, but no, he won't be on any of the small teams being formed. Why? He's too much of a driven individual, an entrepeneur who thinks too highly of his own opinions. He knows he'd be a terrible team member. Wise man. (The original reason he gave for not going was that he's found a very nice girlfriend, thankyou, and she doesn't want to go. That's also a good reason for staying firmly on this planet. I sympathise.)

Slow down for a moment, though, and think about this I'm-going-to-Mars thing.
What will it really be like for the successful candidates? Mars One is picking out teams of four from the thousands who applied. A large part of their training will consist of spending months together, in those small groups, stuck in some Arctic region or in a desert, in a simulated Mars colony base. The Mars Society is carrying out a similar project.

The Mars Society will attempt to conduct a one-year
simulated human Mars exploration mission in the
Canadian high Arctic at its Flashline Mars
Arctic Research Station (pic: Mars Society).


Have you ever spent a few months with three other people? It's hard even to imagine. Sailors of small ocean yachts may have a good idea of the psychological tensions and pitfalls. That odd habit of speech or physical mannerism that seemed so trivial in normal life may become a major cause of stress when cooped up for long periods. People's minor character flaws that you hardly noticed before could gradually become a saw blade, grinding away at the fabric of the team.
Artist's concept of the Mars One outpost simulation (pic: Mars One).
So it's good that the Mars One teams will be stewed in the pressure cooker here on Earth, to expose problems like this. As a writer, I'm fascinated in how these people will resolve these tensions. It makes for a good story. As someone who's been married now for 13 years, I can tell you that in a close relationship, unless both parties are willing to change, there will be frequent bursts of unpleasant fireworks. The everyday phrase 'swallow your pride' becomes one of the most challenging proverbs, some days. It's something like trying to gulp down a chicken without first taking out the bones. Who would want to do such a thing?
I think those colony candidates will come out of the Colony Simulation training either spitting vinegar at each other or counting their three teammates as their best friends forever. And judging by the high motivation and calibre of many of the applicants, I'm guessing it will be the latter.

Mobile posting -catching up

Here I am writing about cutting-edge space science and this is the first time I have ever posted from my cell phone. It might not become a habit. My samsung galaxy does have a voice input app built in, but it is not making it easy for me. Keypad is making a tough training ground for my hand-eye coordination.  Etc. Etc. If you use one of these, you know what I mean... unless I'm hopelessly behind the 30 to 50% of the human race who probably use these things their whole waking lives. (I guessed the %).
No doubt it's been said many times but these tiny handheld boxes are good on mobility but short on ability compared to 'grownup' devices.
So do you want me to link this to the current blog theme of life on Mars? Ok. How many years will it be til a marstronaut will post blogs from some handheld while roving across the cratered terrain of Arabia Planitia or another of that planet's stunning vistas? Would anybody dare hazard a guess? And what will they be blogging about?

Echoes Of A Greater Invitation

Some advocates of space exploration point out the statistical risks of large rocks colliding with the Earth and bringing our civilisation to its knees and causing untold suffering. "So let's get up there and learn how to deflect the rocks!" they say. I can see the sense in doing so. Any effort to defend the defenceless and bring help to those in need is right up my street, as one who attempts to follow the example of Jesus. (Read: stumbling, hesitantly, trying to keep up... )

The Hayabusa probe, developed by the Japan Aerospace
Exploration Agency (JAXA) to return a sample of material
from a small near-Earth asteroid in 2005.

Others now are developing robotic - and then crewed - spacecraft to explore and exploit the mineral wealth of the same asteroids - Near Earth Objects, as they're sometimes called - saying that this will boost the global economy. And I think they're probably right.

Planetary Resources' proposed Interceptor, a low
cost asteroid mission that enables accelerated exploration

As you can see from my other posts, though, the most stirring and visionary reason I can see for developing reusable, affordable launchers and capabilities for long-duration space missions is to allow human beings to settle other worlds such as Mars. Elon Musk, brilliant and innovative billionaire founder and CEO of SpaceX, aims to build a colony on Mars in order to make humanity a 'multi-planetary species' - ie. a species able to survive disasters such as careless asteroids falling on our homeworld. He really is trying to save the world! Correction - trying to save the species...

Reaching and settling Mars is often cited as the New Frontier, a huge task for freedom-loving people that will re-ignite the vitality and spirit of New World settlers during the seventeenth to nineteenth centuries.

Didn't you feel your blood stirring just a little when Mars One issued its invitation for colonists? Of course, when they realised that the colonists were expecting to live the rest of their lives on Mars, most people drew back and would not consider the offer for themselves, however much they might identify with the aims of Mars One.

However, it also resonates with me, this plan for the 'marstronauts' to lay down their Earthly lives and devote themselves to a great, historic cause. Colonising Mars in itself I think is a worthy vision, but not so much in the manner of Elon Musk. I just believe that all the Universe is God's Universe and it's our honour and privilege to be able to explore it, live in it, and look after it responsibly for the good of all.

But seeing the Mars One recruits get ready makes me think how each of us is called to an even greater challenge, whichever planet we happen to live on.
Jesus said, “Whoever wants to be my disciple [meaning, apprentice or student] must deny themselves and take up their cross and follow me. For whoever wants to save their life will lose it, but whoever loses their life for me will find it. What good will it be for someone to gain the whole world, yet forfeit their soul?" (from Matthew's Gospel, chapter 16)

We Jesus-people may look odd to others, or may be mistaken for the American Right, but what we're called to do is to live a radical life of love in the footsteps of our Master. That's something that has been changing the world for the better for the past twenty centuries (with some notable failures and fakes).

Oh, and the long-term survival of the species is already assured, Elon. Forever. To join up, you just have to leave everything behind and follow Jesus into his New World.

Reaching for Mars

Credit: NASA/Pat Rawlings, SAIC

Below I've listed a few of the resources and ideas that I've found so far concerning the colonisation of Mars. Elsewhere, if you look hard, you'll find better lists (with prettier pictures too) but this is my handful of data and perspective on the subject.
Here are some organisations actively involved in research or with the stated aim of establishing a colony on Mars. (It's easy enough to search Facebook for Mars groups for yourself, and some of them are fairly sane too.)
Its founders include Robert Zubrin, an innovative rocket scientist formerly at Martin Marietta, a visionary speaker and writer. His practical ideas ended up being too far ahead of the establishment, so he resigned and founded his own company. Now NASA and virtually the whole space exploration movement acknowledges that his 'Mars Direct' plan is basically where it's at. 
The Mars Society has established two simulated Mars bases, one in Utah, one in the Canadian Arctic. Volunteer scientists go and stay there to do real research relating to Mars.
Their mission statement includes the following:
 The purpose of the Mars Society is to further the exploration and settlement of the Red Planet.
SpaceX: Space Exploration company with sights set on colonising Mars.
SpaceX's visionary owner, Elon Musk, is a daring billionaire. It's said that big money hates taking risks - thus, nearly 50 years after the first Apollo moon landing, humans-in-space still consists of a few people hanging out in low Earth orbit. And the rockets and hardware in use now are based on '60s designs. Really.

Enter Elon Musk and his 3000+ employees. They've gone through the design of rocket launchers with a magnifying glass to find out how to make it cheaper to build and fly rockets to orbit. And they're well on the way to making the world's first fully-reusable rocket launch system. (No, the Space Shuttle wasn't fully reusable. Only the winged beast was; the boosters and external tank weren't truly reusable).
What does this have to do with a Mars colony? Obviously to get there you need to launch a great deal of equipment - and some people - from Earth to orbit. That's actually the most expensive part. SpaceX is lowering the cost per kilo of launching to Earth orbit by innovating, testing and flying new things. Right now their engineers are developing the Raptor rocket motor which will be powered by methane and oxygen. So far, most heavy-lift motors use hydrogen and oxygen. But hydrogen's very hard to store long-term, and methane can be manufactured fairly easily on Mars (or it can even be found and used on many asteroids).
What is more, Elon Musk has strongly expressed his vision to 'make humanity a multi-planetary species' by building a large and lasting colony on the Red Planet. He plays his cards close to his chest, so there aren't many details available and there's plenty of speculation, such as this 'fan art' concept of SpaceX's Mars colony Ship:

I expect you've heard of this one so many times already. Bas Lansdorp, founder of Mars One, wanted to go to Mars as a boy after watching an early Mars probe on TV. Now he's an entrepeneur, recruiting thousands of potential Mars colonists for a one-way trip to begin a colony there. He admits he doesn't have the team-building personality to make a good crew member, so he won't be going himself, at least not at first.
Here is their own list of web links related to their grand scheme: be continued!

Progress on Mars Writing

Told you I'd be gone for a while. It's a long way to Mars and back!
So far I have a mass of notes (or should that be a mess? Yes, it should.)  Topics include:
·         Private space corporations
·         Asteroid mining
·         Mars remote sensing research
·         Astrobiology
·         Which universities do postgraduate research in astronautics?
·         Mars One
·         The large body of Mars fiction, from 1880 to the present
Almost nothing of the story is written beyond note form. Here's a snippet of what could be an interlude in the form of Facebook-type messages:

In Another Land

My other news is that I'm finding myself drawn to explore the planet Mars.

Ever since Mars One's co-founder Bas Lansdorp, M.Sc, went public with his plan to send colonists on a one-way trip to the Red Planet, I've been ever more fascinated with the whole project. A decade or more ago I read Kim Stanley Robinson's Mars trilogy. It felt like I was really there, half the time. Great stories, but Kim sends 100 colonists all at once. Mars One plans to send them about 4 at a time.

So my next writing project, after publishing Called To Battle, will be a novel about colonising Mars. The more I look into it, the more detail I find. There's a whole new world to learn about. This will be a story for adults, so the science needs to be well-researched and believable.

Wish me bon voyage. I may be gone some time.

Meet the Man From The Moon

Imagine meeting a lunar astronaut. What would you ask him? Science fiction author and astrophysicist Gregory Benford met Buzz Aldrin in the 1980s.

I read this and felt the historic weight of frustration that Apollo astronauts, among many others, have felt since the moon landings.

Gregory Benford's writing, by the way, is top-notch science fiction. He knows the science and he writes good fiction.

Zac Manchester Blasts Off!

Here's a guy who had a great idea and wouldn't give up until he had got the thing working. Zac is a graduate student at Cornell University in New York. His vision: Design and fly a spacecraft that anyone can afford.

Intrigued? Disbelieving? Have a look. It's called KickSat.

With thanks to the BBC News for the pic

The BBC News page where I saw KickSat first is here.

The Man Who Works On Mars

Seriously! This man's job involves driving cars on the surface of the planet Mars. He was born in Italy, his father was a school teacher who loved carpentry. Take a look! He says the reasons that most of the other drivers have left the job is that:
1) Google pays more
2) Driving cars on Mars can get boring!

Here's some advice from this driver, Paolo Bellutta :
"What advice would you give to someone who wants to take the same career path as you?
You never know what can help you, so learn everything you can! I often used knowledge I gathered while pursuing my hobbies, or talking to friends or reading non-work-related books."
