A NEW GOLDEN AGE OF SPACE EXPLORATION?

Image Credit: NASA/JPL-Caltech

Unless you keep up with current space news, it may be easy to feel that the Golden Age of space exploration is behind us. After all, the last time humans set foot on the Moon was the Apollo 17 mission in 1972. Heady stuff, but really, there hasn’t been much going on since, has there?

Actually, the amount of space exploration that’s been happening in recent decades is astonishing. It’s just that almost none of it has involved human crews. The one major exception is the International Space Station, which recently marked twenty years in space (its first components and first occupants were launched in November 1998). It’s been continuously manned since November 2000, and has hosted 227 crew and visitors, some as many as five times. It’s operated by a partnership of five space agencies (representing 17 countries) and has been visited by citizens of seventeen different nations. I’m not sure which is its most important contribution: the amount of data the ISS accrues every single day about how humans can live and work in space, or what it teaches us about the international cooperation needed to make us a spacefaring species. Nonetheless, because the ISS has been around for twenty years, and we can even watch it go by overhead, the general public probably underestimates its importance and may simply have lost interest.

So what else has been going on?

2004 may seem like a long time ago, but do you remember the European Space Agency’s Rosetta mission to comet 67P/Churyumov–Gerasimenko? We watched its Philae lander drop toward the barbell-shaped object with fascination, and held our breath as it bounced and ended up at a angle that prevented it from collecting solar energy, which spelled its doom. But we did witness comet off-gassing and a snowstorm. Then in January 2005 NASA’s Deep Impact mission visited two other comets, 9P/Tempel and 103P/Hartley.

The Dawn spacecraft was deactivated just one month ago after visiting the asteroid Vesta and the dwarf planet Ceres (in the asteroid belt), producing amazing photos and detailed maps of these remnants of the solar system’s formation (or possibly fragments of a planet that broke up). It was also an important test of ion thrusters for propulsion instead of standard rocket motors.

NASA’s New Horizons mission to Pluto was a huge success in 2015 when it sent back photo after brilliant photo of the icy world and its moon Charon, after already providing fantastic imagery and data from Jupiter and the Jovian moons in 2007 en route. But New Horizons isn’t done yet. It’s speeding its way toward a Kuiper Belt object designated as 2014 MU69 (nicknamed Ultima Thule, meaning beyond the farthest horizon) and will reach it this coming New Years Day (Jan. 1, 2019). Such objects are also thought to be leftover material from the solar system’s formation, probably slush and ice balls—after all, that’s the region most comets come from.

Although it met its end a little over a year ago (Sept. 15, 2017), deliberately plunged into Saturn’s atmosphere, can we forget the awesomely majestic pictures provided by the Cassini-Huygens probe? It spent thirteen years exploring Saturn, its moons and its rings, and the results were astounding.

Fast forward to this year: NASA’s Parker Solar Probe was launched in August 2018 and will fly through the outer atmosphere of the sun, known as its corona, seven times closer to our star than any spacecraft before it. But the big attention this week was the successful arrival of the InSight lander on Mars, which is tasked to penetrate into the Martian soil and probe the crust of the planet for the first time. Because of the high risk of failure, the landing got ‘live’ coverage and lots of media attention when it succeeded.

Yet we shouldn’t forget two more asteroid missions: the Japanese Hayabusa2 spacecraft, which has dropped a small lander onto an asteroid named Ryugu and is still in orbit there, and the NASA OSIRIS-REx probe that will arrive this Monday Dec. 3, 2018 at the asteroid Bennu. (Both of these asteroids are called “diamond-shaped” but they remind me of those old pressed charcoal briquettes for the barbecue!)

In the meantime, there have been lots of missions within the Earth-Moon system, and the U.S. is working with private companies and other countries toward a return by humans to the Moon by 2023. Closer to home, there have been important advances in rocketry, especially from Elon Musk’s company SpaceX. The SpaceX Falcon 9 rocket is capable of launching satellites, and then landing safely back on Earth, enabling it to be re-used (most recently on Nov. 15th). This is a vital advancement toward making commercial uses of space affordable. And, of course, the SpaceX Falcon Heavy rocket, the most powerful launch vehicle in current use, ostentatiously launched a Tesla Roadster into space Feb. 6, 2018 on its first test flight, carrying a mannequin nicknamed Starman in a space suit at the wheel.

Why is all of this important? What are the benefits?

If you’re reading a blog like this, you probably don’t need a sales pitch. But the more we learn about how the cosmos, our world, and our species came about, the more we can predict where we will all go from here. That’s just good survival protocol. Exploratory missions to comets and asteroids in particular are potential goldmines of information about the early solar system, but also may answer the question of how life arose on Earth, since scientists speculate that life here may have come from “out there”. They could also bring us closer to understanding how to protect ourselves from extraterrestrial microorganisms drifting down onto our planet from the far reaches of space. Not to mention identifying potential collision risks to our home from all of the celestial objects whizzing through the solar system.

The more we can learn about how humans can survive, thrive, and work in space environments, the closer we come to making use of them in ways that will benefit all of us. Conditions of zero-gravity, readily-available vacuum, and deep cold can facilitate the production of medicines and other exotic substances very difficult to make on Earth. Mining of asteroids, the processing of ores, and other manufacturing processes performed in space could bring much needed relief to the stressed environment of Earth. If we can find other places to live, or adapt other places to make them liveable for humans, we can help ease the population pressure on our home planet and, maybe more importantly, ensure that humanity would no longer be at risk of extinction from a planet-wide disaster.

Even the process of all this exploration is beneficial. Partly because of the cost in resources, material, monetary, and mental, large-scale endeavours like these demand international cooperation at government and corporate levels, but also one-on-one between members of space crews. Our best hope of survival as a species is to curb our tendency toward conflict and live together peaceably.

Exploration? Oh yes! And I haven’t even mentioned astronomical endeavours like the Hubble and Kepler telescopes that have peered into the farthest depths of the universe and confirmed the existence of planets around other stars.

A Golden Age? Actually, that’s selling it short. This kind of exploration is priceless.

VACATION AMONG THE STARS

Poster from NASA Jet Propulsion Laboratory

Take a once-in-a-lifetime vacation among the stars!

Or at least among the planets. And moons. And asteroids.

OK, not quite yet. But we can go a long way in our imaginations, especially with the help of the NASA Jet Propulsion Laboratory’s new series of travel posters.

The travel posters are the work of JPL’s The Studio: “a design and strategy team that works with JPL scientists and engineers to visualize and depict complex science and technology topics. Their work is used in designing space missions and in sharing the work of NASA/JPL with the public.” And the posters are available for you to download or print off free-of-charge to help your imagination take you all over the solar system and beyond. Fine print at the bottom of each poster explains the known facts behind the artists’ inspiration.

On planets like Jupiter and Venus, we’re only likely to be able to establish a human presence in their upper atmospheres—Jupiter’s gravity and atmospheric density would crush us any lower than that, and Venus’s high atmosphere is its only zone with human-friendly temperatures and survivable pressure too. But what about a Jovian balloon ride or a visit to a Venusian cloud city?

Who knows what sights can be seen from dive suits or submersibles in the ocean under the ice of Jupiter’s moon Europa? (Scientists and SF writers have considered Europa one of the most promising places in the solar system to find extraterrestrial life.) Or maybe an exotic boat ride on one of the liquid methane lakes of Saturn’s planet-sized moon Titan is more to your taste. From there you could skip over the rings to Enceladus and gaze at the famous geysers.

If we ever get the hang of interstellar travel you might check out the twin suns of Kepler 16-b (and pretend you’re on Tatooine with Luke Skywalker), or the red sun of Kepler-186f (like Krypton—do you think we yellow-sun-dwellers might gain super powers there?), or try skydiving on HD 40307g with its extra thick atmosphere. If you’re a true party animal and night owl (or an actual vampire who shuns the light of day) then the place for you would be PSO J318.5-22 which looks to be a rogue planet without any nearby star to give it light. Neverending nightlife!

Sure, a lot of this is speculation and all of it involves flights of fancy, but these free posters from NASA could be a great addition to the bedroom of a young budding astronaut. Or equally good for grown-ups like us who still allow our inner child to dream and dream big.

AAAAH, BUT NOT AWE

NASA New Horizons image of Pluto's moon Charon

I recently listened to a podcast interview with science fiction writer David Brin in which he proclaimed that the past year was the best year ever for space exploration.

He made a good case for the claim: perhaps the biggest space story of the year was the New Horizons spacecraft’s flyby of Pluto in July that offered some truly stunning photos of our one-time ninth planet. But it was far from the only story. After visiting the asteroid Vesta a few years ago, NASA’s Dawn spacecraft went into orbit in March around the other major dwarf planet in our system, Ceres, the largest object in the asteroid belt. The European Space Agency’s Rosetta craft continued to follow the Comet 67P/Churyumov-Gerasimenko in its path around the sun, even briefly regaining contact with its lander Philae on the surface of the comet. A Japanese probe successfully made orbit of Venus (on its second try) and an Indian Mars probe was a thorough success.

Private space companies had a couple of setbacks, but significant successes too. Blue Origin was able to safely land a rocket booster on its tail, like something out of 1950’s space movies, and then SpaceX topped that by launching eleven satellites using its Falcon 9 rocket which was then successfully landed back on the launch pad for re-use. That technology should reduce the cost of sending things into space by a huge margin, which could well kick-start a revolution in the exploitation of space.

It’s been an amazing year.

Did anyone notice?

Oh, I know there were always some trending stories on Facebook and Twitter, but did anybody except science nerds and science fiction writers actually get excited—really celebrate the milestones being achieved? I don’t think so, not to the extent that they deserved. It seems as if, in these times when almost the whole of human knowledge is available to us through the internet, we take for granted that everything worth knowing is either already known or soon will be. Through digital media we’re constantly bombarded with new discoveries (many not yet substantiated) in the fields of medicine, physics, biology and, yes, astronomy…so the extraordinary achievements of space engineers who manage to hurtle high tech robots over ten-year-long trajectories to planets nearly five billion kilometers away just become more of the same. Expected. Not quite routine, but not life-altering. Not landmark events in the fabric of our lives.

Or maybe I’m blaming the wrong thing. Maybe we’ve become so used to seeing science fiction movies and TV shows with exceptionally realistic special effects that the actual pictures of a real place like Pluto fill us with aaah but not awe. We see rugged Plutonian plains of nitrogen ice, geysers on Jupiter and Saturn’s icy moons, rocky planetoids spinning in the vastness of space, and we say, “That’s cool” and move on to an article about the next iPhone, or ads for the next model of aerial drone. I don’t really know the reason. I know that in the middle of the last century each new achievement in space made us think of gleaming cities with tube trains or monorails, passenger rockets to Mars, and fantastic floating colonies in high Earth orbits. Now they only lure our minds away for a few minutes from thoughts of climate crises, terrorist threats, and burgeoning epidemics.

When did hope and wonder give way to fear and gloom anyway, and why? Hope and wonder are a lot more fun.

The next time you see photos of a new space discovery, take a few moments to really picture the scene. Picture the incredibly talented team of dedicated people that made it happen, the vastness of space and the incredible unlikeliness of the amazing objects out there, and our being alive at this time in history to witness it. Let the wonder really take hold.

Of that feeling are bright futures made.

THE BATTLE BETWEEN SPACE FACT AND SPACE FICTION

Credits: NASA/JHUAPL/SwRI

We live in an era when a spacecraft can send us pictures of the surface of Pluto that are nearly as good as what we’d see out the window of a jetliner flying over our own planet. Take a look at some of the newest images processed by NASA’s New Horizons team—they’re astonishing. Mountains, gulleys, long running cliffs. As a science fiction writer I could place an astronaut on the dwarf planet, maybe climbing out of his crashed utility ship and hiking toward the nearest outpost, and I could describe real ridges and crevasses he’d have to cross on the Sputnik Planum, foothills and passes between ice mountains that he’d have to traverse. No invention necessary, just a close look at some high resolution photographs. What’s more, I would do that to add authenticity. The downside? No playing fast and loose with Pluto’s geography or geology now that we actually know what it is. If I had written such a story a few years ago I’d be second-guessing myself and wondering if I’d blown it by featuring a feature that’s not really there.

Of course, that’s been the case for stories set on Mars for decades now and the Moon before that. Still, Pluto?

Oh well, at least there are other solar systems to play with, right? Sure, except now with the Kepler Space Telescope and new sensing techniques, scientists have found nearly two thousand planets around other stars (as of this writing the count according to NASA’s Exoplanet Archive is 1,916 confirmed with another nearly 5000 candidates). We know a lot about some of these planets, like roughly how big they are, whether they’re likely gas giants or rocky worlds, how close they are to their sun (giving a good idea of their surface temperature) and sometimes more. I’ve written stories and novel manuscripts that feature an expedition to another star system or even a colony there. Until they’re published I have to keep checking to see that reality hasn’t overtaken fiction—if it suddenly turns out that there are no planets where I’ve placed mine, or even that I’ve put an Earth-type world where there’s actually a Neptune-like planet, some major rewriting would be in order (once they are published I’m stuck eating crow, at least until the next edition!) The writers of the new Star Trek series will have to check the latest stats on each star system before the Enterprise warps in and sends an away team down to the surface of a planet that doesn’t exist, because you’d better believe there are viewers who will check (and probably flame them on social media if they screw up).

As if the situation weren’t tricky enough, the James Webb Space Telescope is scheduled for launch in October 2018 and will not only be able to see small planets that Kepler and the Hubble telescope can’t, it’ll be able to study the atmospheres of planets Kepler can barely detect. That’s power. It will be amazing. It could also be responsible for a sudden rash of science fiction writers with strange patches of missing hair.

You might say, no big deal, we still enjoy stories by Arthur Conan Doyle even though we know there are no hidden plateaus in South America where dinosaurs live. True, but no science fiction writer wants their work to be relegated to that category in their lifetime, believe me.

What’s to be done? I suppose we could set our stories farther and farther away from Earth, decreasing the likelihood that new facts will outdate our old fiction, but to my mind the near impossibility of reaching somewhere like the far side of the galaxy would be a more serious breach of scientific knowledge than the odd invented planet. Perhaps we could create tales of human beings placed a long time ago in a galaxy far, far away, but then you’re entering the realm of fantasy rather than science fiction (not that there’s anything wrong with that).

Really, though, it’s no different than having to keep up with the amazing progress being made in other branches of science—all we as writers can do is embrace the excitement of new discoveries, be inspired by them, rejoice in our progress as an ever-curious race, and do our level best to get it right. And readers can forgive us our transgressions. We hope.

Here’s to new eras of scientific discovery and great science fiction.

THE MARTIAN IS A MODEL FOR SCIENCE MOVIES

Movie poster for The Martian from 20th Century Fox

 If you’ve read the bestselling SF novel The Martian by Marty Weir, you’ll know it’s not a stretch or an insult to describe it as MacGyver On Mars—the plot depends on stranded astronaut Mark Watney using every piece of available technology, biology, and chemistry in creative ways to help him survive the hostile Martian environment. Weir does it brilliantly, with just enough human touches to keep the reader fully invested in Watney’s survival in spite of numerous technical descriptions that some will find dry. Translating such a science-heavy story into glossy Hollywood entertainment for today’s average moviegoer would seem to be as daunting a challenge as surviving on Mars.

Congratulations to Ridley Scott & Co. for pulling it off with flying colours. I hope Hollywood will take the movie version of The Martian not only as proof that science movies can be successful but as a model for how to do them well.

When a ferocious sandstorm forces a crew of NASA astronauts to cut short their stay on Mars, Mark Watney (played by Matt Damon) is injured and thought to be dead. The crew is forced to leave him behind and return to Earth. The next Mars mission can’t happen for another four years—Watney has enough food and water for a couple of months. His personal survival and any attempt by NASA to rescue him appear to be impossible. Both will require the utmost in human determination and ability to achieve.

In The Martian nearly every character is a scientist—Watney himself is a botanist as well as an astronaut—yet the movie shows that they can be every bit as committed, stubborn, inventive, defiant, funny, sweaty, and courageous as any spy, cop, or soldier. They’re not superhuman, instead they show the best qualities of real human beings and the astonishing things we can achieve. The story isn’t about great feats of daring and stamina (though there’s certainly some of that), but using human ingenuity to overcome seemingly insurmountable problems one step at a time. As the implacable universe throws up each new roadblock, Watney, or the NASA team trying to bring him home, uses brainpower to figure out a way around it.

The scientific explanations are necessarily brief but not absent. When a risky course of action is suggested, the pros and cons are explored honestly. The unpleasant realities of both physics and economics are given fair representation and, true to the book, The Martian escapes being propaganda for the USA by giving an important role to the Chinese space program. I’m deeply impressed by how Ridley Scott has crafted a slick and suspenseful Hollywood offering while keeping it so well balanced. Others have pointed out that it is a rare movie full of optimism. Sure, it has moments of carefully-crafted theatre, but it’s inspirational in a true sense and not just emotionally manipulative.

I can’t talk about a movie like this without mentioning the special effects and they are terrific—eye-popping and authentic (OK, we wouldn’t hear rocket engines in space and the Hermes spacecraft wouldn’t have such big windows, but otherwise…). The Martian vistas are stunning, well worth the extra price of seeing them in 3D. The movie reportedly cost $108 million USD to make and it shows on the screen. Not all of that is Matt Damon’s salary, though he certainly earns his pay by giving Watney just the right amounts of stoicism and nerdiness to grab the audience and hold them—it could so easily have failed in the hands of another actor.

The Martian is a movie without any killing, martial arts, fleets of helicopters, contrived romance, explosions meant to destroy or terrorize, inane humour, super powers or supervillains. So it’s truly a breath of fresh air. I hope box office numbers will show Hollywood that there’s an appetite for this kind of movie and at least one director who knows how to make them.

WHY ALL THE FUSS ABOUT NEW HORIZON?

NASA photograph--The last taken before the New Horizon spacecraft flew past Pluto.

On July 14, 2015 one science news story dominated all others: the NASA New Horizon spacecraft’s flyby of Pluto. Considering that the last time Pluto got so much attention was when it was demoted from full planet status to the demeaning designation of “dwarf planet”, you might easily wonder why there was so much excitement about New Horizon. Commentators have even sometimes neglected to stress the dwarf planet thing, almost as if the former ninth planet had regained its status. It hasn’t. But it is a star in terms of fame.

New Horizons was launched in January 2006 (ironically, the same year as Pluto’s demotion) and after traveling nearly five billion kilometres finally raced past Pluto at a speed of more than forty-five-thousand km/h, so there wasn’t a lot of time for sightseeing. Much like your last budget bus tour of Paris. It couldn’t even send pictures “live”—NASA was forced to wait a while for them (remember dropping off the film of your bus tour at the drug store for processing?) In fact, New Horizons is gathering so much data that it will require sixteen months to send it all back to Earth. That’s what you call shutter happy.

Why so much interest? If you ask me, most of us still think of Pluto as the ninth planet, and it was the only one left that hadn’t received the up-close-and-personal paparazzi treatment. Even in the Hubble telescope, Pluto was little more than a blurry white ball. Now we’ve seen its cracks and craters, wrinkles and blemishes, in high resolution, finally completing our solar system postcard collection. But Pluto has had a special allure because it was the most distant of the planets and so the most mysterious. It also has an orbit very different from the rest of the family, leading to speculation that it’s an adopted child born somewhere else and then captured by our sun. If so, learning as much as we can about Pluto will also help us to learn about things much farther away.

Pluto is part of the outer fringe of the solar system, known as the Kuiper Belt. If we ever hope to travel to other stars we should know as much as we can about that stretch of space and the more distant Oort Cloud. Our spacecraft will have to travel through them. Maybe we’ll want to use Kuiper Belt objects as fuel depots or rest stops, or maybe we’ll just want to know how to avoid all of them, but knowledge is the key. It could be that Pluto and other dwarf planets like Eris (almost twice as far away) will actually become launch stations from which freshly-fuelled interstellar spaceships will begin their long voyages.

Pluto might seem too far away to consider it as a candidate for industrial mining, but then we don’t know what’s there. It might turn out to be rich with resources. If it really did come to our system out of interstellar space, it might have significant quantities of elements that are otherwise rare in our neighbourhood. Exploratory missions like New Horizons will help to provide those answers.

So let’s give Pluto its time in the spotlight. The poor demoted planet deserves a break.

LIFE IS A TREASURE WORTH FINDING

I’ve posted recently about the search for extraterrestrial intelligence and the (so far) lack of success. But why are we so focused on intelligence? Wouldn’t it be awesome enough just to discover life elsewhere in this vast universe? Jumping high-five awesome? For some reason most of the attention and all of the angst has been centered on the idea that there might be other species of beings out there that might be interested in us for the purposes of a) contacting, or b) conquering. Yet the search has come up empty. Well, maybe intelligent life is as rare as a politician with his hands in his own pockets, and there are lots of reasons it could remain hidden from us, but the discovery of any kind of life inhabiting other solar systems would be cause for celebration.

This week NASA announced a brand new coalition of scientific endeavours to be known as NExSS (Nexus for Exoplanet System Science). Each of the partner projects will focus on different aspects of the search for extraterrestrial life including refined spectrometers better able to detect Earth-like planets, how planets form and where, the potential habitability of exoplanets (from a human perspective), tidal dynamics, how organic elements reach planet surfaces, and a lot of other topics.

I love this idea, and not just because of its geek-cool acronym. The practical side is that the more we know about how habitable planets get that way and how life arises and survives elsewhere, the better we can understand the challenges of our own planet and maybe even find solutions to the damage we’ve done to its ecosphere. God knows, we need all the help we can get in that department. But beyond the practical is the pure stomach-tingling thrill of a treasure hunt. Finding carbon-based life on an exoplanet would be like finding a long-lost cousin you never knew you had (who doesn’t know about all the skeletons in family closets). No, bigger than that—it would be like living all your life in a sheltered village and suddenly finding out that there’s a whole world just beyond the trees. There was a hint of that when the first exoplanets were discovered in the mid 1990’s, but the confirmation of extraterrestrial life would ramp that excitement up to a whole new level. Think of all of the new questions, and the answers, and…more questions.

Does carbon-based life require DNA? A cellular structure? Does it always follow a birth-to-death life cycle, or could there be forms of life that are effectively immortal? What about sex—we’re always fascinated by sex.

What if we find life forms that aren’t based on carbon? There’s been speculation, but proof would really upset the bioscience applecart. And that could be a good thing. Sometimes the best way to advance is to throw everything you’ve known up in the air and see what new patterns form when it lands.

Whatever we learn about life elsewhere is bound to open our eyes to secrets our own planet has yet to offer up, because I’m certain we haven’t yet found every type of life the Earth has produced, hidden in the depths of the ocean or the planetary crust. Not to mention other bioscience implications like the discoveries of new potential medicines. Learning how extraterrestrial life copes with unique or harsh conditions might teach us how to protect ourselves from nasty surprises like cosmic ray bursts or asteroid strikes, too.

Most of all, I love this plan because the discovery of life elsewhere would give us somewhere to go and a reason to get there. The human race is at its best when we have goals that inspire us, nearly unattainable heights to climb. A treasure just beyond our reach that requires us to dig deep within ourselves and strive together in community.

We could really use something like that right now, and NExSS just might point the way.

SPACE SUBMARINE OR QUIXOTIC COLONY?

The space news that catches your interest this week will probably depend on whether you think space exploration requires direct human involvement or not. If you feel that it just isn’t the real deal unless humans in space suits are landing a rocket ship on another planet, then you’ll probably be most interested in the latest from the Dutch non-profit organization known as Mars One.

In case you’ve forgotten, Mars One is the groups that plans to start sending astronauts to colonize the planet Mars, four at a time, beginning in 2024. The catch is, it’s a one-way trip; the would-be colonists will never be coming back to Earth. If things go according to plan, they’ll get new companions (and supplies) every two years, but no return flight. The selection process for the astronaut colonists has involved applications from around the world—more than 200,000 of them to begin with, which was whittled down to 1,000, then 660. And now the final 100 have been chosen. So here’s where the real circus—I mean, science—begins, as the finalists try to survive in a mock Mars habitat while the cameras roll to produce a reality-TV show (one of the methods of financing the project, don’t you know). You can watch a promo here. Oh, did I mention that one of the finalists is a 38-year-old from Poland who calls himself “M1-K0” and claims to already be a Martian?

A very different space story involves NASA’s release of a video featuring a concept submarine proposed for the exploration of the hydrocarbon oceans of Saturn’s giant moon Titan. Titan is a strange place, with a largely nitrogen atmosphere, a landscape of dunes, frozen methane snow (and a little water ice) plus large lakes or small oceans of a hydrocarbon mixture. Even so, many scientists feel Titan may be a good candidate to find forms of life, probably in those oceans. So it would be most helpful to have a space probe that could explore beneath the surface. Hence this submarine proposal. But before you go picturing a space-suited Captain Nemo piloting the sub through undersea canyons and past bizarre creatures, the truth is the probe will be robotically controlled. It’ll surface from time to time to send data back to Earth, but no astronaut submariners will be involved. And the mission is still a good number of years away, with some pretty big hoops to jump through first.

I’ve said before that I think the Mars One project is doomed to fail, hopefully before any volunteers commit elaborate suicide by rocketing off toward the red planet. If I were a betting man, my money would be on the Titan submarine mission as the one more likely to succeed. BUT, speaking as a fiction writer, there’s only so much drama I can create around a robot probe in a sea of frozen BBQ fuel, whereas dozens of novels could be written about the Mars One venture.

So let’s keep our fingers crossed for the success of the cautious, well-reasoned-and-researched approaches to the exploration of space, and leave the dramatic failures to the world of fiction.

WALL STREET IN SPACE

When you think of space travel, do you think of NASA? The Russian space program? The Chinese government?

Old thinking, because the newest players in space may be taking over the game. I’m talking about global corporate interests. Big money. While governments continue to keep the budgets of organizations like NASA in near-starvation mode, the corporate stars of the world are stepping to the front of the line. People like Richard Branson of Virgin Airlines, Larry Page of Google, Elon Musk from PayPal, Amazon CEO Jeff Bezos. They’ve been getting together over martinis (or something expensive) and forming new companies to explore—and exploit—outer space. We’ve known for some years that Virgin Galactic plans to fly tourists to the edge of space and back (for $200,000 a crack, thank you very much), and they are getting closer to their first paying trips. I’ve written before about SpaceX, whose Dragon spacecraft are already flying supply missions to the International Space Station. But there are also new startup companies like Moon Express, preparing to build (and use) landers for the Moon. Planetary Resources intends to mine asteroids, and maybe even save us from those threatening meteor strikes we keep hearing about. Deep Space Industries is another would-be mining company. And we shouldn’t forget less commercial, but equally enterprising ventures like Inspiration Mars (mentioned in my last post), planning to send a married couple to Mars in about five years from now, and Mars One, a group that hopes to have a colony on the Red Planet by 2023.

These people are not fruitcakes, but some of the most successful entrepreneurs in the new economy. And their plans sound like fantastic dreams, but they’ve got solid scientists working with them. The space race is going corporate.

Was this inevitable? Since we taxpayers tend to cast our eyes closer to home on our hospitals and our roads, maybe governments just can’t continue to back the exploration of space and it’s up to the moneymakers to do it.

You can see the attraction for them. Talk about your offshore tax havens! Claim an asteroid and make the rules—who’s really going to stop them? Laws? The law of gravity is the only really important one, and it’ll ensure monopolies for the companies rich enough to break it. But lets not forget tourist opportunities: what high roller wouldn’t want to show off to his friends in a casino in Earth orbit, with all of we peasants zipping past below?

By the way, we’ll still be funding all of these ventures—by being the customers of Google, PayPal, Amazon and the like, and then buying the products these new companies bring back from way out there.

But we shouldn’t be surprised. Did you think Columbus sailed to America because he felt like tanning on a new beach?

REAL SCIENCE STILL FIRES THE IMAGINATION

It’s always interesting to follow the top science stories and let your imagination run free. For any SF writer, I’d say it’s an essential exercise. Over the past week:

Remember all the fuss in 2006 when Pluto was downgraded from planet status to the new category of “dwarf planet”? That was because other bodies just as large had been discovered beyond Pluto’s orbit (Eris, Haumea, and others) and within the asteroid belt (Ceres). Scientists got their first good look at one called Makemake recently when it passed it front of distant stars. Unlike Pluto, Makemake appears to have no atmosphere, although its covering of methane ice might vaporize when its orbit brings it to its closest approach to the sun. Dwarf planets aren’t exactly hospitable, but they’d be a whole lot more accessible than the gas giants like Jupiter and Saturn. Even the concept of asteroids or dwarf planets being converted into giant luxury resorts isn’t so far-fetched. A continent-sized skating rink, anyone?

Meanwhile, John Grotzinger, project scientist with NASA’s Mars Rover mission told an NPR reporter that a chemistry lab aboard the Curiosity rover had made a discovery that would be one for the history books, but he refused to elaborate until the data has been thoroughly checked. That set off a flurry of speculation—the discovery might be anything from definite signs of life (my own opinion) to proof of space aliens (I really doubt it). Definitive proof of life beyond Earth will finally give science fiction writers license to embody just about any setting we can imagine with exotic species (we do it anyway, but we’d really love to be able to say, “I told you so.”)

A third story involved the hunt for the ultimate sub-atomic particle, the famous Higgs boson, the proposed particle at the very root of physical structure that would complete our picture of why objects have mass. Scientists at the Large Hadron Collider near Geneva, Switzerland are nearly certain that they’ve found it (or at least confirmed its existence by observing its by-products). Yet there’s been a measure of disappointment in the announcements. The particle appears to behave exactly according to theory, but that’s the problem. If it had been found to have unexpected properties, that would have been a step toward confirming some of the more exotic theories of physics. As it is, the straightforward Higgs boson just adds support to the current model of the universe. So what’s left to discover? To the particle physicists I say, “Don’t worry”—in 1900 Lord Kelvin is reputed to have said, “There is nothing new to be discovered in physics now; All that remains is more and more precise measurement.” It may have been a misquote, but the opinion wasn’t uncommon at the end of the Victorian era. It wasn’t true then and it isn’t true now.

I’m still confident that the universe is as limitless as our imagination.
