Nitrogen Powered Rockets (For Titan, Triton And Pluto?)



(Image: A prototype of the Mini-Helicon Plasma Thruster. Credit: Donna Coveney / MIT)

Out "in the black" where the suns rays are much dimmer, future explorers will have to come up with innovative ways to travel to and from the gas giants, dwarf planets and the various moons that dance around their parent worlds.

While solar sails, magnetic sails and nuclear rockets could provide some measure of transport, they will probably be too expensive for the average star ship.

Since mining hydrogen directly from gas giants is suicidal due to their deep gravity wells and very fierce winds (with the only exception being Uranus), colonists beyond Jupiter may look towards nitrogen to solve their space transport needs.

(Space Travel) Massachusetts Institute of Technology researchers say their new rocket -- called the Mini-Helicon Plasma Thruster -- is much smaller than other rockets of its kind and could consume just one-tenth the fuel used by conventional systems. [...]

The scientists said the Mini-Helicon is the first rocket to run on nitrogen, the most abundant gas in Earth's atmosphere. Batishchev noted, however, it could be years before the technology can be used commercially.

While this technology will have some value on our home world, these nitrogen powered rockets may prove invaluable to worlds like Titan, Triton and Pluto who seem to be blessed with an abundance of nitrogen, respectively.

If future settlers could find ways to harvest this element from these worlds, then humanity may discover a means to travel not only throughout the outer planets, but perhaps beyond the Kuiper belt as well.

One Solar Space Power To Rule Them All?

Note: Article inspired by NASA Watch, The Planetary Society and 21st Century Waves


Warning: This is an extremely long article, so you may want to grab a quick snack as you read through this post.

Anyone who has ever played board games such as Risk and Monopoly knows that the overall purpose of the game is for one player to dominant the board by either taking territory or securing financial resources ahead of their rivals.

The same rule also applies to the final frontier as evidenced by the space race emerging in Asia, as well as between the US and China.

While every nation probably has their own "road map" for conquering the final frontier, there are no less than five critical locations (ranging from asteroids to dwarf planets to even moons) that a space faring nation must secure if they desire to remain (or become) a solar space power in our star system.

First Stop: Luna

Orbiting a mere light second away from Earth, the Moon could easily be described as humanities second home due to its proximity towards our birth world.

Although the lunar surface may lack water (at least in abundance), its white regolith can be "easily" converted into breathable oxygen, allowing our species to survive beyond our earthen cradle without the need to constantly borrow air from our home world.

Often seen as free on planet Earth, oxygen in space will be literally worth its "weight" in gold, and any nation that can find a way to inexpensively produce lunar oxygen will have an advantage later on over its rivals (and may even be able to sell the precious gas for a profit).

While its oxygen rocks could enable humanity to live off world, its reduced gravity may make the tiny sphere appealing to asteroid miners seeking out near earth objects (aka NEO's).

Since micro-gravity has a way of eroding bones and muscles, destroying immune systems, weakening hearts and strengthening deadly bacteria, asteroid miners may prefer to live lunar side (with frequent trips to mine these NEO's), than to spend the majority of their time floating next to a space rock in micro-gravity.

Even though a space faring nation (both current and aspiring) could develop a sustainable presence around the Moon (and nearby space rocks) due to its resources and location, it may be wise to travel beyond Earth's orbit towards more promising worlds (in order maintain its status a future space power).

Next Stop: The dwarf planet Ceres

Although some would consider it "insane" to skip the red planet, heading to Ceres first will ensure that a future space power has the resources to fund its expansion (note: despite the fact that doing so means sacrificing the prestige of sending the first man or woman to Mars).

Ceres strategically orbits within the metal rich region of the asteroid belt, making this dwarf planet prime real estate (at least to asteroid mining corporations).

Any nation establishing a colony on Ceres would be able to send teams of astronauts to secure nearby metallic space rocks as their own, potentially selling them to future allies or harvesting the mineral resources for themselves.

While the dwarf planet lacks any resources of its own, Ceres is suspected of hosting more "fresh water" than Earth itself, which would enable future asteroid minors to potentially grow their own food off world without depending on frequent supplies from Earth.

It would also allow Ceres to act as a interplanetary rest stop between Mars and Jupiter, not to mention a safe haven as well (just in case the asteroid belt becomes infested with space pirates).

Since most of humanities attention will probably be focused on Mars after the Moon, there will probably be very little competition establishing a dominant presence on Ceres (if not conquer it entirely for themselves).

Third Stop: The Martian moon called Phobos

Despite its popularity in science fiction, Mars will probably attract very few visitors due to the extreme difficulty in landing large payloads on the surface of the red planet.

Coupled with the fact that Mars lacks major resources of any kind (note: at least that we know of), the crimson world may only be inhabited by scientists, various cults and individuals disillusioned by Earthen (and Lunar) governments.

Even though the red planet may not be of much economic worth (at least initially), one of its asteroid moons Phobos could be converted into an enormous space station in order to make it easier to process metals harvested from the asteroid belt.

Since the sunlight on Mars is much stronger than in the asteroid belt, a future mining corporation could use the Sun's rays to melt asteroid metals en mass before exporting them towards Earth (and Luna).

Although working on an asteroid moon may be profitable, living upon one may not due to the side effects of micro-gravity.

Even though a future miner could always counter the effects of micro-gravity with various drugs and electronic shocks, it may be wiser to settle upon the red deserts below as Mars's gravity is approximately 38% Earth norm.

In order to reduce the cost of transporting personal (and equipment) to and from the Martian surface, a future space power may need to construct an "orbital space elevator" on the near side of Phobos.

While constructing this would ultimately open up Mars to the rest of humanity (which a future space power could charge a fee for rivals to use), it would also allow them to import water from the Martian surface (instead of depending upon either Earth or Ceres for supplies).

Fourth Stop: The Jovian moon Callisto

Often regarded as a dead world, the Jovian moon Callisto may be of high worth to any space faring nation, due to the fact that it is one of the few radiation safe worlds in our star system.

Even though Mars and the Moon may have "celebrity status" throughout our solar system, neither of the worlds has a global magnetic field to protect their spheres from the wrath of the Sun.

Callisto on the other hand is not only protected by Jupiter's magnetic field, but it orbits just beyond the gas giant's radiation belt, enabling future colonists to raise families (and pets) upon this world without fear of growing a third eye ball.

While Callisto may not have any immediate value outside of being a midway point between the inner solar system and Saturn, establishing an outpost here would enable a future space power to "easily explore" its brother Ganymede.

Although Ganymede's orbit takes it into the heart of Jupiter's radiation belts, a properly shielded colony could use Ganymede's global magnetic field to raise an abundance of crops with the help of bees (instead of relying upon ants who may not need a magnetic field to pollinate our green friends).

While it would probably be impossible for one space faring nation to conquer both of these worlds for themselves, conquering these moons early on (especially Callisto) could give a rising space power significant influence over the future of the Jupiteran system (not to mention the next gas giant as well).

Last Stop: The methane moon called Titan

Even if humanity finds a way to harvest the helium-3 locked away within Luna's crust (not to mention the atmosphere of Uranus), the cost of mining it may put it out of reach for most interplanetary commercial spacecraft.

Since supplies of Uranium and Plutonium could easily become unavailable for space travel (as many nations on Earth may need them for energy or defense), finding an inexpensive alternative could determine whether or not a space faring nation thrives or merely survives in the depths of our star system.

One way to guarantee that a future space power has the neccessary fuel to maintain its fleet (at least inexpensively) is to establish outposts near Titan's methane lakes (which may contain an abundance of methane/ethane within them).

While it would not be surprising to see Titan heavily colonized in the fairly distant future (by various countries), securing this world early on would enable a space faring country to establish tremendous influence throughout the solar system (or at least within the ringed system of Saturn).

What about the other worlds?

Although their are plenty of other interesting worlds ranging from the burning crust of Mercury to the frozen wasteland of Neptune's moon Triton, these worlds may not attract that much interest in the future (at least as far as we can tell right now).

Even though everyone probably hopes that humanity would put aside their differences and explore the final frontier in peace, six thousand years of recorded history seems to hold a dim view regarding this viewpoint (as one can glimpse the wars that have raged upon our planet).

Whether or not humanity decides to conquer every sphere and space rock within our solar system only time will tell.

But either way, these four worlds (plus one asteroid moon) may be the key that determines which space faring nation not only dominates our solar system, but perhaps guides us unto the next one as well.

Saturn's Titan: Where Rovers Fail, Hot Air Balloons May Prevail



(Hat Tip: Centauri Dreams, Image Credit: NASA)

To say one could easily explore the surface of Titan without descending below the clouds would be as silly as trying to fathom Earth's oceanic depths without using machines to probe the deep.

If Titan is destined to be a future home for humanity, then we are going to have to find a way to accurately explore its surface.

Since exploring its surface via satellite may be useless due to the methane moon's "jelly insides," we may have to explore it via hot air balloon in order to map out this orange hazy moon.

(Titan and Saturn Future Exploration) We are now in the phase of describing our study of the past year for a return to Titan and the Saturnian System in extensive reports that will allow the science committees appointed by the agencies to evaluate the interest and feasibility of the mission. The JSDT, and the NASA, JPL and ESA engineers have been working hard on putting together these reports and on defining the science, as well as the measurement requirements related to our ambitious mission, which comprises a dedicated Titan orbiter, and two in situ elements : a hot-air (Montgolfière) balloon and a lander. The balloon is to fly over Titan’s mid latitudes at 10 km altitude for about 6 months, while a short-lived probe will land in a north-polar lake. The CNES French Agency has committed to supplying a large part of the balloon, and is actively studying the Montgolfière. For the lander, the flourishing heritage from Huygens is putting us in a strong, comfortable position.

Although some may suggest that we simply deploy another rover (as that will give us a ground view of things), and future machine with wheels my find itself getting stuck due to the chemical nature of Titan's sand grains.

A hot air balloon would probably be a better alternative, as it would not only give us a birds eye view of the region, but enable us to measure what Titan weather is like in the sky (as future colonists will probably construct "nitrogen planes" in order to transport goods across the surface).

Saturn: Titan Colonists May Loathe The Moon's Sand

(Hat Tip: The Space Fellowship, Image Credit: NASA)

Located approximately 1.5 billion kilometers away from the Sun, Saturn's Titan may prove to be one of the more interesting worlds to live upon in our solar system.

While it would not be surprising to see cites constructed upon the moon due to its methane lakes, future colonists may find its sand to be "slightly irritating."

(NASA) On Earth, sand grains form by breaking things down, but on Titan, the opposite may be true - with much of the sand a product of building things up.

That's one theory Cassini scientists are considering after studying Titan's massive sand dunes with the visible and infrared mapping spectrometer on the Cassini Saturn orbiter. The new observations raise the possibility that much of the sand grows from hydrocarbon particulates fallen from the sky that, once on the ground, join together and become sand grain-size particles. [...]

In the May 2008 issue of the journal Icarus Cassini scientists report that dunes contain less water ice than the rest of Titan. The dark brown sands appear to be made up of the same kind of complex organic chemicals that dominate Titan's smoggy atmosphere. If the dunes are made up of the same dark material on the inside as they have on the outside, then there's simply too much organic sand to have come from erosion alone.

The new findings may help explain how, once on the ground, hydrocarbon particulates the size of smoke particles might grow into sand grains through a process called "sintering" - a slight melting that welds particles together. It may be that sintering produces particles that are just the right size for sand grains - between 0.18-0.25 millimeters and no larger, perfect for blowing in the wind and drifting into dunes.


If humanity desires to ever live upon this world, they may have to find a way to counteract this sintering effect, as the last thing colonists need is to have these particles building up upon future spaceports, buildings and homes (not to mention rocket ships).

Saturn's Titan: A GPS Nightmare



(Image Credit: NASA / JPL / University of Arizona)

When camping outside in an unfamiliar wilderness, two essential tools one needs to consider packing are a map, and a compass. While the former is wise so one knows the overall layout of an area, the latter can help you determine which direction the final destination lies.

Aside from Mercury, Earth and Ganymede, most worlds lack a global magnetic field, which means future colonists will have to rely upon a mini GPS system in order to navigate off world.

While a GPS system may sound like a "no brainer" solution for most worlds orbiting our Sol star, it may present a problem for Saturn's methane moon, Titan.

(Planetary News) Since the acquisition of the first SAR swath across Titan in October, 2005, there have been 19 regions on Titan that have been imaged more than once by the RADAR instrument. When the RADAR team assumed that Titan's rotation was synchronous -- that is, that it rotates precisely once with each orbit around Saturn -- features seen during one flyby were observably offset when imaged during another flyby, by as much as 30 kilometers (19 miles). [...]

The measured offset of the surface features, relative to the prediction for synchronous rotation, means that, over the time period measured in the Cassini data (October 2005 to May 2007), Titan's surface was shifting by 0.36 degrees per year. For there to be this rapid of a shift in the position of Titan's surface requires the surface to be able to move freely about the rest of the moon, sliding around atop a liquid interior ocean.


Believe it (or not), Titan's surface is actually being shifted by the moon's winds, which may affect how fast the world spins, not to mention which side faces Saturn.

If humanity ever settles upon that cloaked moon, they are going to have to figure out a way to pin point positions accurately, lest ships miss drop supplies (and colonists) all over Titan's hazy surface.

Radiation Safe Worlds

Of the 83 colony worlds that dance and prance around our golden star, only six worlds (excluding our home planet) hold the potential of being future homes, nine if you include Mercury, Pluto and Charon.

Despite the fact that future technology could eventually open up all of these worlds for human habitation, only a few of them may attract "the masses" after the first person sets foot upon their dusty soil due to the "evil R word"--radiation.

Contrary to the various rumors, taking heavy doses of radiation does not turn one into the Hulk, one of the members of the Fantastic Four or Spider Man via a radioactive spider bite.

Radiation, whether cosmic or solar has the potential of seriously roasting you alive, if not turning one into a vegetable.

Even though humans can tolerate "various degrees" of radiation, our bodies seem to be quite content with the level of background radiation our species receives on planet Earth, which is about 0.35 REM's (aka Roentgen Equivalent Man) a year.

Higher doses of radiation can prove to be fatal towards future colonies, and some researchers do not recommend levels above 50 REM within a year or 25 REM during a 30 day period as it can lead towards some serious side affects (as highlighted in the chart below).




While radiation can be countered by using water, lead and aluminum, parents may be hesitant to breed upon foreign planets and moons (let alone raise kids upon them) if it will result in their children acquiring serious birth defects.

In order to determine which worlds are "family friendly," one only has to look at how much radiation a world receives to determine whether or not it is suitable for large populations or should be left alone for industrial space companies.

Starting out with Mars, one often dreams about metropolises dotting the surface of that crimson sphere. While Mars may hold much promise for future colonies, its annual dose of 15-20 REM may give some settlers second thoughts.

While future Martians may be able to combat the threat of radiation by building cities within its lumpy magnetic field, the red planet as a whole may not spawn dense cities until a globe sized artificial magnetic field can be constructed.

Moving outward to the Jovian system future space settlers may find more fortune living on Jupiter's moon Callisto. Orbiting just outside of its angry parents radiation belt, Callisto receives approximately 0.01 REM a day (or about 3.65 REM a year).

Coupled with its prime location in the outer solar system, Callisto may outpace its Martian rivals population wise, and may be second only to Earth as far as future inhabitants go.

Unfortunately Jupiter's other lunar daughters do not fare as well as Callisto, with all three of these worlds (Ganymede, Europe, Io) bathed in Jupiter's harsh radiation belt, putting them at a disadvantage compared to their much colder, "uglier" sister.





Traveling further outward towards Saturn, one may find it strange that humans may call the smog world of Titan home sweet home. While its surface may be hidden from the human eye, its atmosphere may be thick enough to protect residents from both solar rays as well as Saturn's radiation belts.

Even though there are other worlds such as Luna (aka Earth's moon), Ceres, and even Ganymede that may eventually be civilized by our ever growing race, these worlds may not conquered right away due to the "invisible killer" lurking in the shadows.

While it would not be surprising to see scientists and industrial corporations setting up shop on these hostile worlds, the bulk of humanity may choose to remain on these radiation safe worlds until over population forces them to conquer these overlooked spheres roaming silently among the stars.

Which Worlds Should We Colonize First?


Our race is indeed blessed to inhabit a fertile world that orbits our favorite star, Sol. With 83 colony worlds dancing around our yellow sun, one can only imagine all the possibilities of our brave race inhabiting them all.

Of course, reality has a way of correcting our fantasies, and just as humanity refuses to dwell near or upon certain mountains, canyons and islands, so our young species may opt to skip over certain worlds in order to inhabit others.

So which worlds hold the promise of housing tomorrows children?

The first (and probably most obvious) world earth's kids may call home is the moon (aka Luna). The moon will be humanities first stepping stone way from Earth, and will most like jump start our journey into space, as its soil may contain valuable resources that can pay for all the fancy equipment needed to survive off world.

Skipping Earth's nearest neighbor would probably be disastrous, as our sensitive public is barely able to handle any "boo boo's" that happen in the solar abyss, much less a fatality. If terraforming ever became a reality, the moon would be a prime candidate for another Earth, as it already inhabits the "Goldilocks zone."

Journeying outward, our dusty neighbor Mars would come into play. Despite lacking resources of its own to attract businesses upon its crimson soil, Mars does hold an abundance of water which would make a human settlement somewhat possible upon its rusty surface.



(Video: A visual of what Mars would look like if a large portion of its ice water melted and flooded the planet. Credit: NASA)


Mars is also conveniently located near the asteroid belt, which could help turn this barren world into an industrial paradise. Although other worlds (such as Earth) could always mine the asteroid belt with their own ships, it may be easier (and cheaper) to outsource that task to the Martians, the way many American business outsource their "sneaker and jacket making" to China.

Expanding further throughout the solar system, dwarf world Ceres would come into play. Thought to hold an abundance of water beneath its surface, Ceres could easily serve as a way station, supplying crews with water and fuel in the middle of the asteroid belt.

Entering the realm of the Jovian giant Jupiter, humanity would probably end up settling on Callisto. Not only does this heavily cratered moon harbor life necessities (such as CO2 and water), but it could also serve as a gateway towards the other gas giants.

Although Callisto may play a crucial role in our quest to colonize our star system, its bigger brother Ganymede may end up becoming the Jovian favorite, and perhaps even the prime world of the gas giants.

Entering our last stop would be Saturn's Titan, a world believed to contain multitude of methane lakes. Although Titan's methane weather cycle may be worth billions, its unique environment may become the attraction of the solar system, as its air pressure may make life very interesting for sports enthusiasts, artists and even musicians.

Of all the worlds that orbit our star system, these six worlds will probably be illuminated by the lights of future cities upon its surface.

But what about the other 76 worlds that grace our star system? Are not they worthy of being called home by future residents?

Unfortunately many of these other worlds will probably not be settled due to various reasons (at least voluntarily), although you will have to wait until next week to find out why most of these worlds will probably be skipped by our human race in our quest to colonize the stars.

Note: Due to lack of time images (and video) will be added later.

Update: Added video and images, as well as broke up last paragraph.

Would You Want To Live On Saturn's Titan?


Of all the worlds that have danced around the Sol star, none of them have, or will ever rival our home world Earth. Unparalleled in beauty, the view from a thousand miles away is enough to take one's heart away.

With a world requiring little, if any technology for human habitation, why would any one consider moving towards a moon shrouded in clouds that is over a billion kilometers from the Sun?

Unlike many of the lunar and planetary spheres that float around our Sun star, Saturn's Titan is blessed with an atmosphere that allows humans to walk upon its presence without the need of a standard vacuum suit.

Although early pioneers will need to be well equipped with a "warm suit," such technology may be easier to construct than clothing oneself with material that can withstand zero atmosphere.

Titan's atmosphere is approximately 1.5 times that of Earth. Although the denser air pressure may make walking on Titan feel as if you were at the bottom of a swimming pool, the "heavy" air does have some advantages.

Residents upon this orange world would easily be able to transport themselves around the planet with a pair of "artificial wings," something that would make Leonardo De Vinci proud to hear. This could lead towards Titan being crowned as the solar capital for air sports (such as sky diving, surfing, etc.) and might even lead towards a futuristic "aerial Olympics."

Despite the fact that Titan's clouds block out most (if not all) of the sky, those gifted in the arts may also find Titan's "burnt orange" horizon a welcoming backdrop compared to the pinkish sky on Mars or the blue sky on Earth. Astronomers aside, living within the orange skyline may become a solar attraction, setting the world apart from rivals within the star system.

But if residents are not attracted by either the view of living on a foreign moon or the aerial sports, they will be inspired by the tunes created by the musicians living there. With Titan's denser atmosphere, residents will be able to enjoy a richer symphony of music that will rival--if not surpass--the sounds heard on Earth (provided they can create and play them in the frigid temperatures).





(Video: What music would sound like on Earth, Titan, and Venus. Credits: Edward Willett)

Despite the fact that it will be Titan's methane lakes and scattered ice rocks that will finance and enable future inhabitants upon Saturn's favorite moon, respectively, its artistic beauty and unique environment may keep the masses from moving off world.

Artificial Magnetic Fields For Artifical Worlds



(Image Credit: NASA)


Aside from war and disease, the biggest threat to our (future) space faring species is radiation. Whether it comes from the Sun, a Jovian parent, or from a distant black hole, radiation can easily determine which worlds will be ruled by humans and which ones will be roamed by our robotic friends.

Although many may point to underground colonies as a means to survive on these sterile worlds, such an idea may not attract the masses (as living underground does not provide a glamorous view of the universe). Worse, underground colonies may have a counter affect on us colonizing our solar system, with the vast majority of people opting to live on the home world than off world.

But what if we could construct gigantic magnetic devices enabling a planet or moon to be shielded by a magnetic field? Such a device would enable our species to not only colonize Jupiter's Europa and Saturn's E-ring moons (which are too radioactive for surface habitation, respectively) but also enable various plants and animals to thrive on the red planet.

Without such a device our species would be limited to colonizing Jupiter's moons Ganymede and Callisto, not to mention Saturn's Titan. Although radiation on Mars may be tolerable, it would probably not be the ideal place to terraform as any ecosystems exported there may suffer from the wrath of a solar flare.

Despite the fact that this technology would be centuries away, it may be reasonable to explore current ways of developing artificial magnetic fields, as it would enable us to not only conquer our own solar system, but those that orbit other stars.

83 Colony Worlds Orbit Our Star?

(Hat Tip: Cosmic Variance)

Many space geeks (I included) seem to be excited about an image by KOKOGIAK displaying the 88 largest bodies in our solar system (of which 83 are "terrestrial" or have a surface we can actually land upon).



After searching online on these various worlds, many with an abundance of ice water upon them (a good sign), it became apparent that many of these worlds would not become favorable homes (for raising kids) due to either radiation, distance or lack of appeal.

Currently there seem to be four worlds that show some promise of becoming future homes which are:

  • Mars (which has tolerable levels of radiation)
  • Ganymede (which has a magnetic field)
  • Callisto (which is not within Jupiter's radiation belts)
  • Titan (atmosphere plus Saturn's magnetic field may protect it)

Unless artificial magnetic fields can be created upon other worlds, they may only attract corporate industries and scientists, but not the huge populations necessary in order to establish our species as a "space faring civilization."

Hopefully I'll get some more time to post about these four worlds, as they hold much promise for our race four or five generations from now.

Titan's Weather Could Be Worth Billions


Saturn's most mysterious moon may have a weather system that is potentially worth billions of dollars! Many scientists suspect that Titan's clouds may rain down methane from on high, which would probably explain the existence of those methane lakes that dot the northern pole.

(Saturn Today) A giant cloud half the size of the United States has been imaged on Saturn’s moon Titan by the Cassini spacecraft. The cloud may be responsible for the material that fills the lakes discovered last year by Cassini's radar instrument. [...]

These findings reinforce the idea that methane rains down onto the surface to form lakes, and then evaporates to form clouds. Scientists compare this methane cycle to the hydrological cycle on Earth, dubbing it 'methane-ologic cycle'.

Ground-based observations show this Titan cloud system comes and goes with the seasons. A season on Titan lasts approximately seven Earth years. Based on the global circulation models, it seems that such cloud activity can last about 25 Earth years before almost vanishing for four to five years, and then appearing again for 25 years.


Some scientists think that during the seasonal change that the clouds may reappear on in the south pole, although we will have to wait for a Cassini flyby to confirm that theory.

Although Titan lies almost a billion miles away from Earth, it certainly has not lost the attention of astronomers and may become an OPEC in the solar system as methane could be the fuel to take us beyond Saturn, helping us to colonize not only Uranus, but Neptune and Pluto as well.

Interactive: Saturn's Titan Will Require Space Elevators

Over at Planet Quest, NASA has developed a short, interactive tour that lets audiences know about Saturn's most mysterious moon, Titan.

What made this virtual tour interesting was the fact that according to NASA a single spark would be enough to engulf this moon in flames. This basically translates to the banning of rockets launching from the moon's surface, which requires an alternative method for transporting the methane off of Titan's surface.

It looks like LiftPort's and Black Line Ascension's great grand kids (assuming they will be running the space elevators future franchises) will be very busy in the distant future.

Saturns Lunar Titan May Be Worth Billions

Saturn's moon Titan may be one of the most valuable worlds in our solar system, after Earth and the Moon. Satellite flyby's and lunar probes have revealed Titan to be a world with many methane/ethane lakes dotting its surface (at least in the north).

(New York Times) As scientists have predicted but have had a hard time proving, the surface of Titan, Saturn’s largest moon, appears to be dotted with lakes of liquid methane. The lakes are more intriguing evidence of the active phenomena at play on the only moon in the solar system with a dense atmosphere. [...]

The radar imaging system detected more than 75 dark patches in the landscape near Titan’s northern polar region, the scientists said in a detailed description of the find published today in the journal Nature.

The patches, they said, indicated smooth surfaces in an otherwise rugged topography, suggesting lake beds either partly dry or filled with liquid. These smooth surfaces, more or less circular and with diameters ranging from 2 miles to 40 miles, are associated with channels that appear to have been formed by flowing liquids, presumably tributaries to the lakes.


Despite the fact that conquering Titan is many generations away, the fact that this world harbors fuel resources is a very comforting thought for future colonists. With Saturn orbiting almost a billion miles away from the Sun, solar power may not be an option for those fortunate enough to land on its various moons.

Harvesting Titan's methane may provide a cheaper alternative to nuclear and hydrogen fuel via ice, and may allow humans to further explore our solar system without breaking the bank.

Titan Has Active Volcano's?

It looks like Titan may be able to join the "active terrestrial club" as their are some interesting clues revealing that its surface may harbor some volcanic action.

(New Scientist Space) The brightest spot on Saturn's moon Titan has been seen brightening and growing, suggesting it might be an active volcano, a controversial analysis of images from the Cassini spacecraft suggests. If so, it would be the first indication of current volcanic activity on the giant moon.

Scientists are interested in whether Titan is volcanically active because volcanoes could help supply the large amount of methane seen in its atmosphere. The methane is quickly broken down by sunlight, so it must be getting replenished in some way.


Although not 100% sure, scientist do think that this bright spot may be a volcanic eruption, although instead of magma or water ice (like Enceladus) it may be more of an ethane-methane mixture.

If so, this is good news as Titan lacks the oceans of methane that were once presumed to cover its surface.

Are Titan's Methane Lakes Evaporating?

It is probably a good thing Titan does not have a stock market, otherwise its fuel prices would be jumping through the roof at this news.

(New Scientist Space) A dozen more lakes have been discovered near the north pole of Saturn's moon Titan, according to images from the Cassini spacecraft's latest flyby of the moon. The lakes may be a seasonal phenomenon, filling with methane rain in the winter, then evaporating in the summer. [...]

The lakes may accumulate near the north and south pole in alternating periods when each experiences its winter and lower temperatures lead to more methane rain, [Stephen Wall of NASA's Jet Propulsion Laboratory in Pasadena, California, US.] says.


The key words in these paragraphs is "may," as the scientists seem to be unsure. Hopefully in the not so distant future (say 50 years) we will be able to land either a rover on Titan's surface or send humans to the moon before these lakes evaporate completely.

Ethane Clouds Spotted On Titan

Titan, the future OPEC of the solar system appears to have ethane clouds floating above the north pole. Scientists are speculating whether or not these clouds could produce ethane rain and even snow.

(New Scientist Space) A giant cloud of ethane has been found near Titan's north pole. The finding suggests that ethane rain or snow could accumulate around the moon's poles, partially accounting for Titan's missing ethane oceans. [...]

"We think that ethane is raining or, if temperatures are cool enough, snowing on the north pole right now," Griffith says. "When the seasons switch, we expect ethane to condense at the south pole during its winter."


Titan was previously thought to hold vast oceans, although scientists were surprised to find the surface to be "very sandy" in nature.

The discovery of possible methane lakes near the poles helped raise the value of this cloudy moon, although it may take some time to exploit Titan with it being a billion and a half kilometers away.

Methane Rain On Saturn's Moon Titan

With the discovery of methane lakes near the poles of Titan, some scientists think that violent rain storms may rain down methane on Titan--and perhaps cause flash floods.

(Red Orbit) Might it rain cold methane on Saturn's Titan? Recent analyses of measurements taken by the Huygen's probe that landed on Titan in 2005 January indicate that the atmosphere is actually saturated with methane at a height of about 8 kilometers.

Combined with observations of a damp surface and lakes near the poles, some astrobiologists conclude that at least a methane drizzle is common on parts of Titan.

Other astrobiologists reported computer models of the clouded moon that indicate that violent methane storms might even occur, complete with flash floods carving channels in the landscape.


It was previously thought that Titan lacked methane oceans, although evidence of channels upon the surface pointed to other wise. Although almost a billion miles away, Titan has the potential of becoming a lunar OPEC, exporting its methane fuel for profit.

Saturn's Titan May Have Methane Lakes

Although I am probably late in the game reporting this, apparently Saturn's cloudy moon may harbor hydrocarbon lakes, making the moon prime real estate for colonization.

(Saturn Today) The Cassini spacecraft, using its radar system, has discovered very strong evidence for hydrocarbon lakes on Titan. Dark patches, which resemble terrestrial lakes, seem to be sprinkled all over the high latitudes surrounding Titan's north pole. [...]

Scientists have speculated that liquid methane or ethane might form lakes on Titan, particularly near the somewhat colder polar regions. In the images, a variety of dark patches, some with channels leading in or out of them, appear.


This is good news since it was assumed that Titan lacked methane lakes due to previous snap shots of the world. These lakes are located near the polar regions, although "rain drops" from Titan's atmosphere will hopefully create more of them.

Saturn's Titan A Desert World, Lacks Methane Oceans

It appears as if the world once herald as harboring oceans of methane is nothing more than a dust bowl consisting of sand. Although nearly a billion miles away from planet Earth, this is a major blow to the future Saturn economy and a temporary setback for humanity.

(Universe Today) Radar images taken when the Cassini spacecraft flew by Titan last October show dunes 330 feet (100 meters) high that run parallel to each other for hundreds of miles at Titan's equator. One dune field runs more than 930 miles (1500 km) long, said Ralph Lorenz of UA's Lunar and Planetary Laboratory.

"It's bizarre," Lorenz said. "These images from a moon of Saturn look just like radar images of Namibia or Arabia. Titan's atmosphere is thicker than Earth's, its gravity is lower, its sand is certainly different -- everything is different except for the physical process that forms the dunes and resulting landscape."


Scientists are unsure of what the grains of sand (resembling coffee grounds) exactly consist of. Titan's sand could consist of organic compounds, water ice, or even a mixture of both. There was hope that potential rain may provide a resource for methane oceans, but further analysis reveals that rain is just as common on the world as the Sahara desert.

(Universe Today) Observations and models of Titan show that clouds and rain are rare. That means that individual storms could be large and still yield a low average rainfall, Lorenz explained.

When the UA-led Descent Imager/Spectral Radiometer (DISR) team produced images taken during the Huygens probe landing on Titan in January 2005, the world saw gullies, streambeds and canyons in the landscape. These same features on Titan have been seen with radar.

These features show that when it does rain on Titan, it rains in very energetic events, just as it does in the Arizona desert, Lorenz said.


If Titan did posses oceans of methane, then it would have been able to fund future projects to colonize Uranus, Neptune Pluto and beyond. It seems as if this economic jumpstart may no longer be available for humanity to exploit, so unless a new resource comes along, there will be little motivation to colonize any worlds beyond Saturn.
