Four Quick Scifi Reviews

Thanks to the magic of cable TV and the internet, I recently got the chance to see some on-screen works of science fiction I missed the first time around. So here's some quick reviews of stuff most of you probably already saw years ago. Warning, some spoilers ahead.

First up is Mission To Mars. The very first thing I thought of when I finished watching it was: they made the wrong movie.

For those unfamiliar with the plot, Future Don Cheadle (well, okay, his character, but I can only think of him as Don Cheadle) heads the first manned landing on Mars. They discover a mysterious mountain-sized artifact of apparent alien origin. When they investigate, the artifact reacts with lethal results.

Back on Earth, another Mars mission is launched, and after a lot of hokey melodrama, the follow-up mission arrives on Mars a year later. They find Future Don Cheadle still alive, having somehow survived a year in the first mission's makeshift base. Then they all traipse back to the artifact, figure out how to get in, and discover a recording meant for mankind by a dopey looking extraterrestrial.

The movie was okay up until the first team died, then it segued into dumbness and horrible cliches. But you see, hidden in that mess, was the movie they should have made. I'll spell it out: Future Don Cheadle was marooned alone on Mars for a year with a mysterious, murderous alien artifact just over the horizon. Why didn't they make that movie instead?

Can you imagine how awesome that story could have been in the hands of a better director (sorry, De Palma) and much better writers? Can you imagine his struggle for survival on an alien, hostile world, more isolated than any human being has ever been in all of history? Or the dark terrors that man must have suffered through in his crushing loneliness, with the deaths of his friends and teammates weighing on him, and the alien horror that caused it all just an hour's walk away? In the hideous silence of the Martian night, was there really something moving out there, or was it all in his mind? Was any of it ever real, he wonders, as he skirts the edges of madness for months at a time?

It could have been one of those awesomely dark, complex mindf*ck movies, where both the hero and the audience wouldn't quite know what was going on for sure. And Don Cheadle could easily have been up to the acting task. Instead we got some horribly-staged bad-science melodramic crap with Gary Sinise. Argh. Guess we can just chalk this up to one of those great missed opportunities.

And on we move to Bicentennial Man starrig Robin Williams, and based on an original short story by the great Isaac Asimov. Of the works reviewed here, it was the least annoying, but that was mostly because it was so bland.

Robin Williams plays Andrew, an android employed by a wealthy family in the far-flung future year of 2005. When Andrew begins showing signs of sentience, his family helps him become more independent, and Andrew begins a 200-year struggle to be accepted as human.

This film was actually a lot more true to Asimov's original vision than the movie adaption of the all-but-raped I, Robot that came out some years later. There's even some very Asimovian intellectual dialog toward the end, when Andrew pleads his case before the World Council of Smart Guys, or whatever they were supposed to be. But sadly, the film also lacked a lot of Asimov's playful inventiveness, and there was never any real tension or excitement to interest the audience. A for effort, but C for execution.

Okay, I'll admit it, I never saw the blockbuster Transformers movie until it was shown on broadcast TV a few weeks ago.

The robots were damn cool. I've got to give the film creators that. Visually they rocked, and their characters were actually fairly engaging as well. Or maybe it just seemed that way because almost every single human character in the film was so vastly annoying that the robots just seemed much more likable in comparison.

For those of you still more behind the times than me, or perhaps just never watched any cartoons in the last quarter century, in Transformers, two factions of a race of living robots are engaged in a millennia-old war, and that war spills over to an alternate version of Earth populated by good-looking but vapid idiots.

Okay, I'll admit the soldier characters were mostly tolerable. But every time our hero Teenage Goofball was on screen I wanted someone to smash his mouth shut with a sledgehammer. Megan Fox was indeed nice to look at, but that was about it. Goofball's clueless family apparently was created by an algorithm that averaged every sitcom cliche from the past twenty years, and the government types were so incompetent I expected Inspectors Gadget and Clouseau to show up at any minute to take charge.

But did I mention the robots were cool? Megatron especially, I thought this was the single best version of him. He honestly came across as menacing and dangerous. Optimus Prime was also at his best, as noble and heroic--and surprisingly badass-- as one could hope for. If only the film had more of them and less of Goofball and the sitcom brigade...

The anime series Stellvia ran on Japanese TV in 2003, and is available on DVD and for viewing online.

The series starts with a crackerjack premise: For unknown reasons, the star Beta Hydrus, 20 light years away, suddenly goes supernova. Its radiation pulse hits Earth in the year 2167, devastating the planet. Humanity slowly rebuilds, and even expands into the solar system. But in the year 2356, mankind faces its most grim challenge yet: the physical shockwave from the supernova is about to wash over the solar system, and threatens to annihilate everything. To protect the inhabited worlds, a number of immense foundation space stations are created to coordinate defenses; Stellvia is the one above Earth.

The series focuses on a 16-year-old Peruvian girl named Shima, who is recruited to undergo pilot training on Stellvia. Despite a rocky start (she earns the nickname "Shipon," japanese for 'ping pong', after her disastrous first flight) her genius ability with computers and math quickly allow her to become a prodigy as a pilot.

The series started off so well, it was sad to see it slowly but surely degenerate into a batch of banal anime cliches. The series is definitely shojo in flavor (the anime equivalent of a 'chick flick') but was still smart and original enough at first to keep my attention. But despite being 350 years in the future and set in space with the potential extinction of humankind threatening, we're set up with a lot of japanese high school drama cliches spread out among video-game-like space sequences. All of the secondary characters are forgettable; not necessarily badly done, just nothing about them stood out or made me care about what happened to them.

Then, half way through the series, the supernova shockwave arrives. The apocalyptic event they'd been building up since the first moments of the series, the Doom of Man, the Great Mission, etc, etc. I had to admit I was expecting an epic struggle and confrontation. But it was over in two episodes, and the big danger was resolved by the most horrible anime cliche of all: a big robot with an even bigger gun.

I stopped watching after that, with 13 episodes still to go. It was just too disappointing. Like Mission to Mars, there was a much better story buried in that material, if only someone had bothered to try and dig it out. Oh well. Maybe someday I'll go back and watch the rest, but after the way they handled their biggest and most important storyline, I'm afraid it would be just more disappointment.

But Stellvia did also have a cool opening theme, though.

Fuel Is Expensive (Fiction)

A recent article I read reminded me of a short story I wrote a few years ago. Fuel Is Expensive was originally published in 2006 in Tales of the Talisman Volume 2 Issue 3. Its set in the not too distant future on Mars. Image courtesy NASA.

Fuel Is Expensive
By Paul Lucas

The maser drill slipped from Sam's fingers as a thousand needles of pain sliced into her skull. She fell to her knees in a rusty cloud of Martian dust, hands clawing at her faceplate.

The words returned, so familiar now after a dozen similar attacks, whispered in her mind by a fearful voice she couldn't quite recall. Fuel is expensive, it rasped.

Jesus and Buddha, what did it mean?

"Sam?" Ken's voice in her ear, tinny with radio noise. "Sam! You okay?"

The pain ebbed, the words faded. "I...think so. It just hit me all of a sudden."

"Another migraine?"

"Yeah. A real bastard too."

"Mission Control's going to freak. Thirty billion dollars to get here and we're hurting for four dollar aspirin."

She narrowed her eyes at him, standing a dozen meters away in his bulky white EVA suit. "Thanks. Obvious irony is so much comfort right now."

"All part of the astronaut service, ma'am. But seriously, go back to the hab and lie down. EVA is dangerous enough without a brain bleed. I'll go grab Getch and meet you back there. He can look you over again."

Sam grimaced. Getch had examined her every time she'd suffered through her attacks, but always found nothing physically wrong with her. The prevailing theory was that she was having an allergic reaction to the microfine dust creeping into everything after a month on Mars' surface, but nothing had come of it so far.

Sam methodically packed away the maser permafrost drill and trundled back to the Surface Habitat Module, a grayish, inflatable dome twenty meters across, their base and living quarters since landing on the dark-soiled Chryse Planitia in Mars' Northern hemisphere three weeks ago. A hundred meters behind it squatted their lander, a bulky steely polyp against the pale blue-pink Martian sky.

She waved at Getch on the far hillrise, doing a routine check on the automated fuel plant. Drawing on the carbon dioxide in the thin Martian atmosphere and treating it with the water they mined from the Martian permafrost, they were slowly stockpiling methane fuel to use on the return trip home.

Getch waved back but was busy with a conversation with Ken on a private channel. Talking about her, no doubt.

Getch and Ken were decent enough guys. She had slept with both of them at one time or another on the nine-month trip out, even though that was technically a big regulations no-no. But on a very cramped, very dull voyage out, there was simply not much else to do. It was easy enough to loop old monitor vids of them sleeping separately to Mission Control back Earthside to cover up first one liaison, then the other. Who exactly that fooled was a matter of debate. The people at MisCon weren't idiots, after all, and could probably easily see through the ruse. But no one had said anything yet.

She stripped out of the vacc suit. It was a much lighter model than previous NASA space suits, even though this first flight to Mars was expected to encounter much heavier radiation exposure than any other manned mission. A NASA gearhead had lectured to her about some new breakthrough layer that provided superior shielding, but it always mystified her how they managed to make it so thin that she could never see it.

Maybe that was the problem. Maybe her suit's shielding was wearing away or breaking up, causing the migraines as a preliminary stage to radiation sickness. She should mention the possibility to Ken.

She grunted as the pain in her head returned.

Fuel is expensive.

The words were the strangest part of her attacks. Why did they flash through her mind every time? And who did that strange voice belong to, speaking them?

Thankfully, this migraine was proving to be much less severe than the last one.

Focusing through the dull ache, she shucked her vacuum suit's thermal layer and undersheath and put on her oversized sleeping shirt. She knew from the previous incidents that Getch would want a full physical from her and there was little sense in making things difficult by getting fully dressed and then undressed again.

The headache wasn't going away.

She really should check the vacc suit's shielding while she waited. Sam reached for the vacc suit maintenance tools beside the airlock.

A thousand rusty knives stabbed behind her eyes.

Fuel is expensive.

She screamed.

Then stopped in mid-yell, the pain suddenly gone.

Her hands felt warm and wet. She looked down. They dripped with crimson up to her elbows.

Blood? Oh, God, was she hemorrhaging?

She blinked again.

The blood vanished, her hands normal.

Fuel is expensive.

Her vision swirled as she suddenly realized the hab was gone. She stood trapped in a small, bookish apartment back on Earth. Tidy shelves, cramped furniture, and small paintings drowning on bare pastel walls.

Someone rasped her name from a nearby room.

Bright blood pooled across meticulously polished floorboards, a trail leading to the darkened doorway.

Pain again. Her teeth ground so hard she heard enamel cracking.

Darkness.

- - -

Getch with his shaggy mane of blond hair peered down at her as she blinked her eyes open, a steely-cold stethoscope lodged rudely between her breasts. "Sam?" he asked tentatively. "You okay?"

She slowly sat up, cradling her head, holding onto his arm for support. "What...what happened?"

Both men were still in their EVA suits, their helmets orphaned on the floor by the airlock. "You tell us. We found you passed out on the deck. Was it another attack?"

"Yeah. The worst one yet." She told them about it, even the vision of the blood-stained apartment, shivering as she described how real it all felt. Ken held her fingers for reassurance as Getch pulled off his EVA suit's outer armor to continue his examination. As before, he found nothing wrong with her physically.

"I'll have to run more extensive tests," he said. "But there's only so much we can do here. I'll have to consult with MisCon. Those hallucinations worry me. Maybe we can see if there might be some psychological treatment."

She grunted noncommittally. "But it didn't seem like a hallucination. It all seemed so real."

"I'm sure it did. The brain's perception of reality is pretty fluid, actually. You'd be surprised what it can be fooled into thinking is real."

For a moment, just a brief flash, the apartment she had seen earlier appeared behind Getch, its green pastel walls bright with blood. She blinked and shook her head, and it was gone. She cradled her head in her hands. "Maybe I should just get some sleep."

The mission's medic nodded. "That would probably be best, actually. I'm gonna relieve you of any further duties until we can find out what's happening."

Sam started to protest but Ken cut her off. "I think that's for the best, too. Until we know what's up with all this we can't have you risking yourself."

Outranked and outvoted. "I guess," she sighed. "Just let me know if you find anything."

"You'll be the first I tell," Getch said as the two men helped her to her bunk.

- - -

Fuel is expensive.

She woke in the darkened hab, pain lashing through her. A quick glance at the wall clock and the reddish-black glow outside the small viewport told her Mars was sliding into night. Both men slept on their bunks nearby, separated from hers by a partially-pulled curtain. The pain didn't seem so bad this time. She slowly unknotted herself and made her way to the hab's fresher to take some pills.

As soon as the recycled water in the tiny sink began running, it hit her again.
Fuel is expensive.

She blinked and blood suddenly splashed back onto her arms, redder than Martian sands. She staggered back, mouthing a scream that would not come. She was in the apartment again, the plastic handle of a large carving knife curled into her fingers.

An inferno hotter than the sun crashed through her skull. She thrashed about, her limbs thumping uselessly against the thin plastic walls.

And she remembered.

- - -

Cold stone walls framing colder metal bars. The stench of the scratchy brown toilet. Huddling for hours on a stiff bunk, hating her cell, but hating even more what lay beyond it.

Pushed around at mess. Beaten in the laundry. Humiliated in the showers. Day after day after day. How could she survive thirty more years?

Then two mysterious men came to see here. Impeccable gray suits, their voices as crisp as their attire.

"Sheila Polara?" one asked. "Geological researcher? Did a graduate thesis on primordial Earth geochemistry?"

She gaped, then nodded slowly.

"How would you like to get out of here?"

A flurry of paperwork later, and she was outside, stepping into a taxi. She bawled like a little girl, her relief at escaping those hellish walls that intense. Neither of her primly-suited escorts made any move to comfort her.

An expansive office, severe right angles everywhere. Except for the huge round man behind the fortress of a desk, smelling faintly of sour milk.

His voice was a baritone sing-song, talking to her of a new identity, of limited emancipation, of a historic space mission. She blinked at him, bewildered. But she did not care. It was not prison. She readily agreed.

Then the training. Long, long days and weeks of studying, exercising, and testing, broken occasionally by flight training, exhausting survival courses, technical seminars by the hundred. She met her crewmates, Kentaro Hale and Thomas Getch, coming from hopeless criminal situations similar to hers. The three of them were to go to Mars.

Insanity. Three convicted felons, the first humans on another planet?

The men in the suits were evasive in their explanations. But no longer cold, in pain, and hungry, she could think much more clearly than when they had first brought her from her cell. Over many weeks she eventually pieced together that it was all about the fuel.

It was expensive.

She had traded prison for something far, far worse.

She told her companions, and they all balked. No more training, no more exercises, no more seminars, nothing. She quit. Better the mess and the laundry and the showers than this.

Then their new jailers broke out the needles. And the electrodes. And looked the other way when the beatings and the rapes began. A year-long ordeal of intense hypnotherapy and torture and mind control followed. They wanted perfect astronauts, and they were going to get them no matter what.

Starving, filthy, in agony in a frigid darkened cell, she repeated a mantra to herself over and over all through that year, concentrating as best she could through the drug-induced haze.

Rote memorization was used in schools for so long because it worked so well, wearing a groove in memory paths so deep that people could remember fifty years later things like Oliver Cromwell's middle name, the atomic weight of cesium, i before e except after c. The mantra whispered to herself a thousand, thousand times was a warning she only prayed would survive to whoever or whatever she became.

She didn't remember exactly when she had stopped being Sheila the convicted murderer and started being Sam the perfect astronaut mission specialist. All the horror from that year still cast too many shadows in her memory. Perhaps she would never know.

Fuel is expensive.

One final spike of pain, and the memories crashed to a stop. Darkness reclaimed her.

- - -

Again, she woke up on the examining table with Ken and Getch very worriedly looking down on her.

"Thank God," Ken said as she blinked her eyes open. "You okay Sam? You were out nearly two hours."

She looked at her two cremates, sighed heavily and hugged herself. Everything was so clear now, so lucid, as if it was the first time she had been truly awake in months. "I remember. My husband's name was Gray Valentin. Oh God, poor Gray..."

The men exchanged worried glances. "Um, you never mentioned being married, Sam," Ken said.

She got up and slowly pulled herself to the farside of the room. She looked out the tiny viewport at the fuel processor on the nearby hillock, illuminated by work lights. What she saw confirmed all her suspicions. Bastards.

"Fuel is expensive," she whispered. She had expected to be hit by a wave of agony, but nothing. "My own warning from a lifetime ago. But that's only half the sentence."

Ken walked over to her, laying his hands gently, almost fatherly, on her shoulders. "Sam, if you need to tell us anything..."

She sighed. "Five years ago--I think it was five years--I killed Gray. Stabbed him."

"Sam..."

"We had this hideous fight when he finally blurted out all his sleeping around. We screamed each other hoarse for hours. Finally he slunk away to the bedroom, saying we'd talk more the next day. As soon as I heard him snoring I shuffled into the kitchen for a knife, then went into the bedroom. It slid in so easily. I only remember the first stab, but the police told me I did it twenty-eight more times. He woke up dying, begging for his life, but it was too late."

Ken and Getch stared at her, stunned. "Um, look, Sam, remember those hallucinations you were telling us about? Maybe they're getting worse. Maybe we can get MisCon to cut the mission short. Get you back Earthside at the earliest possible window."

She barked out a short, loud laugh. "NASA already knows all about the 'hallucinations,' Ken. Its why we're all here. Don't you remember?" Her laughter stopped. Of course he didn't. "We're never going back."

She looked over her shoulder and saw their uncomprehending expressions. For them it was too soon. The mission planners must have known their carefully-wrought psychological alterations couldn't last forever, but had time-tabled everything so that the mission would be over long before it became an issue. Getch and Ken would never have a breakthrough like hers until it was too late.

Her migraines were all too transparent a ploy now. A conditioned response. A primal distraction in case one of them began skirting the truth.

She abruptly changed the subject to tomorrow's schedule and the experiments they needed to run. Getch and Ken visibly relaxed, apparently relieved that her "episode" had passed. They were careful to avoid the subject of her odd behavior the rest of the night, but still looked at her with an odd mixture of concern and a little bit of fear.

When they settled in for sleep again, Getch sat at a chair beside her cot, in case she had a relapse. A sweet gesture. But not surprisingly, he was slumped and snoring within an hour.

Getch and Ken had been her friends on this long, long journey to Mars, even her lovers a few times. She knew they cared for her, and would probably do anything to help her. She owed them.

Sam quietly slipped out of her bunk to the equipment locker. There, she dug out the maser permafrost drill she had used earlier. She lugged it toward Getch snoozing in the chair.

Getch blearily fluttered his eyes open as she approached. "Sam, what--"

Sam pointed the drill and toggled the power switch. In a heartbeat Getch's face bubbled as his head was flooded with high-powered microwaves, his skull cracking open from the hideous steam pressure within. Before Ken could do more than stir at the disturbance she walked over and turned the drill on him.

She stared at their ruined bodies for many minutes before she collapsed to her knees, body-wrenching sobs ripping through her for the rest of the night.

At dawn, Sam scrubbed herself long and hard, damning the water rationing, donned her EVA suit, and went outside to lock down all the experiments. When she returned, she reprogrammed the three mission comsats in orbit to begin transmitting, in a non-stop broadband loop, the next fifteen minutes that would be recorded by the hab's internal cameras. She made sure Ken and Getch's corpses were clearly in view.

She was sure that many sites on Earth would pick up the transmissions. By the time NASA got the comsats back under control, hopefully not for weeks thanks to her hastily-hacked programs, the truth would be out.

"It was all about fuel," she said to the cameras. "Spacecraft fuel is very expensive, especially for a manned interplanetary mission. That's why a Mars mission was talked about for decades, but nothing was ever done. Hauling the fuel out of Earth's gravity well and then lugging it all the way to Mars and back would cost many billions of dollars no one wanted to spend."

"One plan was to manufacture methane fuel out of materials on-site. But every automated probe sent to test the feasibility of that failed miserably. A chemical quirk in the Martian environment no one had foreseen prevented it.

"But budget cuts were looming, and both the public and politicians sniveled for a return to Apollo-era glory. The answer: a high-publicity Mars mission. But let's see...how to cut costs? The mission would have to carry all the fuel it would need to get out there and back. Tens of billions of dollars to haul hundreds of tons of exotic fuel on a hundred-million-mile round trip. That would break the back of the cash-strapped space program right there.

"But what if they could cut the fuel costs directly in half? Why not only supply just enough fuel to get there, but not to get back?

"Sounds good, right? Now all you have to do is sign up a crew for a one-way mission. You'd think that would be the hard part, but some wily budget genius found a way. Take people who would never be missed--say, prison lifers who happened to have the right technical backgrounds. Train them, give them new, PR-friendly IDs, and send them off.

"But of course its bad PR to have your crew morose and rebellious over their imminent deaths. So make the crew believe the lies. Through months and months of brain washing, drugs, hypnosis, torture. Drill it into their brains that they never committed any crimes, that the astronaut training program had been their life-long goals. From that moment on, to themselves and to the rest of the world, they were heroes.

"And because they were not coming back, other means of cutting the budget could be taken, like skimping on the radiation protection in EVA suits, then lying about some new non-existent breakthrough layer that we could ever find. Let your suicide crew believe that the fuel processing plant was not really just a pile of soldered-together pipes and an empty tank. Let them believe they would not die a long, lingering, painful death as the food and water and air ran out and that the people back Earthside would just cover it up with some invented system failure, then paint them as noble sacrifices to squeeze out more taxpayer dollars for the budget."

She brought the tip of the maser drill to her temple. Tears brimmed. She was thankful that she at least had given Getch and Ken the mercy of dying quickly and painlessly, when they still believed that they were heroes.

"After all, fuel is expensive..."

Her finger tensed on the toggle switch.

"...But martyrs are cheap."

NASA's Option 5: Deep Space Flight

My last Blog outlined what I thought at the time were the four most likely paths NASA's manned program could take in the coming decades. In brief, they were:

1. Return To The Moon
2. Flight To Mars
3. Space Stations/Orbital Infrastructure
4. Asteroid Exploration and Exploitation

However, according to THIS linked article from the New York Times a panel looking into exactly this issue has come up with a fifth intriguing possibility: deep space flights with no landings.

The panel is calling it by the rather PR-safe title of the "Flexible Path" option, one created as much out of budgetary realities as by the desire to push the US's space capabilities forward. The Space Station is very close to completion, and public opinion is making it very clear that it won't be abandoned anytime soon, as the previous administration had planned to do in a few short years.

However, keeping the ISS going will eat up a portion of the manned space program that wasn't otherwise anticipated, so in order to save money, the panel hit upon the idea of deep space flights for their own sake. Presumably, these flights will do close flybys of important destinations, such as the Moon, Mars, and nearby asteroids, but won't make any provisions for manned landings. The idea is to build up a deep space flight capabilities first as a framework for more ambitious missions to follow in the decades after.

Though this is obviously a compromise solution that will prove a disappointment to many if adopted, it does offer concrete benefits nonetheless. Developing both advanced long-range propulsion technology and the means to create long-enduring space-borne habitats are very important to any plan for expanding a human presence beyond the Earth-Moon system. This strategy would put an emphasis on both kinds of technology, and without having to concentrate on things like landers and planet/moon/asteroid outposts, both capabilities could be advanced faster. Experience with space habitat systems on board the ISS would actually prove very valuable in developing the systems needed for these deep-space flights.

Hopefully, whatever path the administration chooses--either the 'Flexible Path' option discussed here or one of the others discussed in the last Blog--the important thing is that they stick to it long enough to actually accomplish something of value out from it. Hopefully, at least for the sake of the manned space program, we can only hope political winds don't shift too much, or if they do, any new political faction that comes to power will realize the importance of sticking with a long-term plan for space exploration.

Moon, Mars, Space Stations, Warp Drives, Whatever...Just Pick One

THIS linked article from ABC News illustrates why our manned space program isn't much farther along than it is.

Every four or eight years, either we elect a new president and/or a new political party takes power, and the space program undergoes yet another overhaul. Programs that have been moving forward for years are often suddenly disrupted, delayed, or canceled altogether. The history of NASA is literally littered with the epitaphs of otherwise promising projects like the SSTO or X-33/Venturestar.

Unfortunately, space has proven too difficult an environment in which to do anything quickly or easily. Apollo with its breakneck pace of historic accomplishments turned out to be the exception, not the rule. We need long term commitment to a single vision of space exploration/exploitation in order to really accomplish any major worthwhile goals.

Though I doubt we'll ever see one any time soon, what we should have is a national referendum on space. The public should weigh in on exactly what we should try to accomplish in space, and whatever administration is in power should follow that as a guideline, instead of just canceling or downgrading projects out of spite against the previous administration, something both political parties have been guilty of for decades now.

But which general plan would the public back? Actually the best way we can decide this is educating people on the general directions the space program could take.

As an example, four feasible general strategies are outlined below. It should be noted that none of these are mutually exclusive; one can eventually lead into one or more of the others very easily.

Return to the Moon: This is the strategy outlined by the Bush administration in 2004, which NASA had been working toward since. I should note that I was not a fan of many of the previous administration's science policies, but I do think its 'refocusing' of the manned space program was spot on, especially since the retirement of the shuttle fleet was inevitable. The Constellation vehicle system under development was specifically geared for this mission.

The purpose of this strategy was not only to send more Apollo-style manned missions to the Moon, but to establish a permanent manned presence there in the form of a moonbase. The advantage of a Moon goal is that it has been underway for half a decade now and is already fairly well developed. As a result it could probably be achieved sooner than the other strategies outlined here. Also, the experience of building and maintaining the ISS would come in very handy in creating a slowly expanding moonbase. For long term benefits, the Moon offers vast resources, particularly the potential fusion fuel helium-3, that could produce a potential windfall for any country that gain a significant lead in developing them.

Mars: The second most talked-about path, many Americans want to forge directly ahead to the Red Planet on one or more grand voyages of human discovery. It is perhaps the most romanticized of the strategies, very appealing to generations of Americans who grew up on the space exploration adventures of various scifi heroes.

The advantage of this plan would be mostly in the technology that would developed in order to make it viable; namely long-term space habitat systems and true interplanetary manned spacecraft. The human exploration of another whole planet would also be very valuable, conducting observations and experiments that current robotic probes aren't easily capable of. But more, a human being stepping onto the surface of another planet would be a monumental historical event that would resonate for generations.

Going to Mars would be the longest-range goal discussed here because of the immense distances and logistics involved, and could actually incorporate a return to the Moon and/or a manned asteroid rendezvous as an intermediate step.

Orbital Infrastructure: Instead of manned exploration, NASA concentrates much more on building up potentially useful and profitable structures in Earth orbit. This is not necessarily a stay-at-home strategy. Post-Apollo, NASA had a 'Grand Architecture' vision for space, focusing on building up a 'step ladder' of stations leading out into the solar system. The shuttle and the ISS as they were originally envisioned were just the first two major projects of this architecture.

In this vision, NASA maintains the ISS as long as possible and follows up with bigger, more advanced stations, as well as other useful orbital structures, such as solar power satellites, orbital hot labs, zero-g factories, or perhaps even a launch tower or space elevator. The idea would be concentrate as much as possible on making space much more of a money making venture than it is now, and use the built-up infrastructure to eventually build the interplanetary craft needed to carry humans further into the solar system.

Asteroids: Somewhat of an underdog compared to the others, its still mentioned occasionally in various sources. Instead of concentrating on 'major' bodies such as the Moon and Mars, emphasis for this strategy is placed on the manned exploration and exploitation of near-Earth asteroids. Technical difficulty would be somewhere between returning to the Moon and sending expeditions to Mars. And with thousands of potential destinations, NASA could be constructively busy for decades.

This strategy has two major potential pluses over the others. First, Asteroids taken in their thousands represent an immense treasure trove of mineral wealth; an estimate of single typical nickel-iron asteroid from a few years ago put the worth of the asteroid's minerals and metals at over $12 trillion.

Second, asteroids can be made mobile using even today's technology. It would be a very slow and gradual process, but valuable asteroids can be 'herded' closer to Earth, inserted either into an L4 or L5 Lagrange point or into Lunar orbit, where they can be much more easily studied and harvested. Hollowed asteroids also offer ready-made armor against radiation and impact hazards in space, and small, properly hollowed and modified asteroids could serve as the chasis fo interplanetary craft.

Which strategy would be best? That would depend on the goals people wanted to accomplish. All have advantages that could benefit not juts the US, but the world beyond as well. However, if we want to see any of these objectives succeed in our lifetimes, we have to pick one and stick with it.

The Public vs the Scale of the Universe

Most people have trouble intuitively grasping the scale of the universe.

Its not that we have problems with the numbers. Most people can bandy the facts and figures around pretty easily. Approximately 238,000 miles to the Moon, 93 million miles to the Sun, 4.3 light years to Proxima Centauri, and so on. Not too much difficulty there.

But visualizing those distances accurately is not instinctive at all. In a way, we're built against that--we have only these analog animal brains of ours, after all. Our minds are hardwired by evolution to deal with things on a human scale, and as a result we tend to mentally shrink everything down to that scale so we can more easily handle it, no matter how inaccurate that view may be.

You can see this popping up a lot in science fiction. The popularity of Space Opera science fiction, for example, can at least partially be credited to how it shrinks travel to other solar systems down to a human scale, with interstellar travel taking days or weeks at the most and entire planets usually represented by over-simplified sets of cities and environments. Space-borne disaster movies such as Armageddon or the more recent Moonfall suffer from this as well, portraying human nuclear weapons as being able to do more than imperceptibly nudge massive celestial objects like the Moon or a moon-sized asteroid. Trying to move the Moon with nuclear weapons would be like trying to propel an aircraft carrier out to sea by hitting it in the stern with a handful of firecrackers.

But I think this lack of understanding scale also colors how the public perceives a lot of scientific endeavors, and usually not for the better. For example, there recently have been a rash of blogs and opinions online complaining about how NASA has waited so long to return to the Moon or to mount an expedition to Mars...almost as if the Moon were right next door and Mars was just a jaunt down the street.

But the failure here is really in understanding just how far away even the Moon is, and how difficult it currently is to send people there. A round trip would cover a distance of roughly 20 times the circumference of Earth. When was the last time any one of us circumnavigated the globe even once? Even with modern commercial jets, how much would 20 such trips cost you in terms of time (both in preparation and in actual flight), resources, and money? And that would just be a taste of the raw distance involved. A trip to the Moon, performed entirely in hard vacuum and microgravity, would be far more difficult and expensive than that.

It was done before during the Apollo program, of course, with great difficulty and risk. But the problem is, we found nothing on the Moon that made it worth the expense for astronauts to return. Its not that the Moon doesn't have valuable resources we can use, its just that with our current level of technology we can't build up the infrastructure there to profitably exploit them. Why? Because the Moon is just too damn far away, and sending things there has proven just too expensive so far as a result.

And Mars is much, much worse. At its closest approach, Mars is about 36 million miles from Earth, or about 1440 times the circumference of Earth. How long and how expensive would 1440 trips around the world on commercial airlines be to you? Now imagine doing it twice, as you'd probably want a return trip back to Earth as well. Now imagine how difficult and expensive a flight that distance through a hostile, deadly void would be in a spacecraft using current technology.

Like the Moon, its not as if Mars isn't ripe with valuable resources and potential scientific discoveries. But we just don't have the technology yet to reach all that distance and set up all the infrastructure that would be needed to make it worth the expense.

In the future, of course I think things will turn around, with the development of faster, better propulsion ssystems and more long-enduring and reliable life support systems. But as much as we may want that to happen in the near future, its much more likely that it will not happen for decades yet.

If people, especially those controlling the purse strings in Congress, understood just how vast the distances were out in space, I think they'd understand the need for more long-term planning and execution in the space program. We have to break out of the short-sighted cycle of trying to restart the space program every 4 or 8 years whenever we have a new president.

And I think the public in general would be more supportive of space efforts, knowing how daunting the task faced by NASA and other space agencies are. I think educating people on the true scale of things should begin in the science classroom, and science writers--and even science fiction creators--should be mindful of trying to convey that when it comes up.
