Birth of an Idea: Seedlings

alien-worldHey all! Hope this holidays season finds you warm, cozy, and surrounded by loved ones. And I thought I might take this opportunity to talk about an idea I’ve been working on. While I’m still searching for a proper title, the one I’ve got right now is Seedlings. This represents an idea which has been germinated in my mind for some time, ever since I saw a comprehensive map of the Solar System and learned just how many potentially habitable worlds there are out there.

Whenever we talk of colonization, planting the seed (you see where the title comes from now, yes?) of humanity on distant worlds, we tend to think of exoplanets. In other words, we generally predict that humanity will live on worlds beyond our Solar System, if and when such things ever become reality. Sure, allowances are made for Mars, and maybe Ganymede, in these scenarios, but we don’t seem to think of all the other moons we have in our Solar System.

solar_systemFor instance, did you know that in addition to our system’s 11 planets and planetoids, there are 166 moons in our Solar System, the majority of which (66) orbit Jupiter? And granted, while many are tiny little balls of rock that few people would ever want to live on, by my count, that still leaves 12 candidates for living. Especially when you consider that most have their own sources of water, even if it is in solid form.

And that’s where I began with the premise for Seedlings. The way I see it, in the distant future, humanity would expand to fill every corner of the Solar System before moving on to other stars. And in true human fashion, we would become divided along various geographic and ideological lines. In my story, its people’s attitudes towards technology that are central to this divide, with people falling into either the Seedling or Chartrist category.

As experts in nanotech and biotech, they establish new colonies by planting Seeds, tiny cultures of microscopic, programmed bacteria that convert the landscape into whatever they wish. Having converted Venus, Mars, and the Jovian satellites into livable worlds, they now enjoy an extremely advanced and high standard of living.

The Chartrists, on the other hand, are people committed to limiting the invasive and prescriptive nature technology has over our lives. They were formed at some point in the 21st century, when the Technological Singularity loomed, and signed a Charter whereby they swore not to embrace augmentation and nanotechnology beyond a certain point. While still technically advanced, they are limited compared to their Seedling cousins.

terraforming-mars2With life on Earth, Mars and Venus (colonized at this time) becoming increasingly complicated, the Chartrists began colonizing in the outer Solar System. Though they colonized around Jupiter, the Jovians eventualy became Seedling territory, leaving just the Saturnalian and Uranian moons for the Chartrists to colonize, with a small string of neutral planets lying in between.

While no open conflicts have ever taken place between the two sides, a sort of detente has settled in after many generations. The Solar System is now glutted by humans, and new frontiers are needed for expansion. Whereas the Seedlings have been sending missions to all suns within 20 light-years from Sol, many are looking to the Outer Solar System as a possible venue for expansion.

exoplanets1At the same time, the Chartrists see the Seedling expansion as a terrible threat to their ongoing way of life, and some are planning for an eventual conflict. How will this all play out? Well, I can tell you it will involve a lot of action and some serious social commentary! Anyway, here is the breakdown of the Solar Colonies, who owns them, and what they are dedicated to:

Inner Solar Colonies:
The home of the Seedlings, the most advanced and heavily populated worlds in the Solar System. Life here is characterized by rapid progress and augmentation through nanotechnology and biotechnology. Socially, they are ruled by a system of distributed power, or democratic anarchy, where all citizens are merged into the decision making process through neural networking.

Mercury: source of energy for the entire inner solar system
Venus: major agricultural center, leader in biomaterial construction
Earth: birthplace of humanity, administrative center
Mars: major population center, transit hub between inner colonies and Middle worlds

Middle Worlds:
A loose organization of worlds beyond Mars, including the Jovian and Saturnalian satellites. Those closest to the Sun are affiliated with the Seedlings, the outer ones the Chartrists, and with some undeclared in the middle. Life on these worlds is mixed, with the Jovian satellites boasting advanced technology, augmentation, and major industries supplying the Inner Colonies. The Saturnalian worlds are divided, with the neutral planets boasting a high level of technical advancement and servicing people on all sides. The two Chartrist moons are characterized by more traditional settlements, with thriving industry and a commitment to simpler living.

Ceres: commercial nexus of the Asteroid Belt, source of materials for solar system (S)
Europa: oceanic planet, major resort and luxury living locale (S)
Ganymede: terraforming operation, agricultural world (S)
Io: major source of energy for the Middle World (N)
Calisto: mining operations, ice, water, minerals (N)
Titan: major population center, transit point to inner colonies (N)
Tethys: oceanic world, shallow seas, major tourist destination (N)
Dione: major mining colony to outer colonies (C)
Rhea: agricultural center for outer colonies (C)

Outer Solar Colonies:
The Neptunian moons of the outer Solar System are exclusively populated by Chartrist populations, people committed to a simpler way of life and dedicated to ensuring that augmentation and rapid progress are limited. Settlements on these worlds boast a fair degree of technical advancement, but are significantly outmatched by the Seedlings. They also boast a fair degree of industry and remain tied to the Inner and Middle Worlds through the export of raw materials and the import of technical devices.

Miranda: small ice planet, source of water (C)
Ariel: agricultural world, small biomaterial industry and carbon manufacturing (C)
Umbriel: agricultural world, small biomaterial industry and carbon manufacturing (C)
Titania: agricultural world, small biomaterial industry and carbon manufacturing (C)
Oberon: agricultural world, small biomaterial industry and carbon manufacturing (C)
Triton: source of elemental nitrogen, water, chaotic landscape (C)

NASA’s Next Mission to the Moon

moonThe buzz about NASA is that the human race is once again going to the moon, and planning to stay there! According to space policy expert John Logsdon, there are plans to establish a manned base on the dark side of the moon under the Obama administration. He further indicated that with the election pending, this news has been kept under wraps. But with Obama now secure in a second term, it is expected that there will be an announcement soon.

“NASA has been evolving its thinking, and its latest charts have inserted a new element of cislunar/lunar gateway/Earth-moon L2 sort of stuff into the plan,” said Logsdon in a recent interview with SPACE.com. “They’ve been holding off announcing that until after the election, noting that NASA’s mission, direction, and budget could have been revised under a Romney administration.”

For those who have been following the Obama administration’s plans for space, this should not come as a surprise. In 2010, the president signed the NASA 2010 Authorization Act into law, a bill which freed up $60 billion for NASA through 2013. This move was intended to reignite space exploration at a time when the US found itself lagging behind Russia, China, the European Union and India in terms of bold new space projects.

These project include a planned asteroid visit by 2025 and a manned mission to Mars in 2030. A manned outpost at the Earth-moon L2 “gateway” (shown in the diagram below) could serve as an important stepping stone to the outer solar system. But right now, NASA’s eyes are firmly fixed on Mars itself, since a manned mission is the next logical step in their research of the Red Planet.

NASA_moon“There are many options – and many routes – being discussed on our way to the Red Planet. In addition to the moon and an asteroid, other options may be considered as we look for ways to buy down risk – and make it easier – to get to Mars.” At a conference held this past September, NASA deputy chief Lori Garver went even further to outline NASA’s goals for the coming years:

“We just recently delivered a comprehensive report to Congress outlining our destinations which makes clear that SLS  – NASA’s new heavy-lift “Space Launch System” – will go way beyond low-Earth orbit to explore the expansive space around the Earth-moon system, near-Earth asteroids, the moon, and ultimately, Mars. Let me say that again, we’re going back to the moon, attempting a first-ever mission to send humans to an asteroid and actively developing a plan to take Americans to Mars.”

Suffice it to say, NASA is happy the election turned out the way it did. With their budget secure, the course of future space exploration has been set and remains in effect. Who’s to say where it will take us beyond Mars? To the Jovian satellites of Europa, Ganymede and Io? The Saturnalian moons of Titan, Rhea, Dione and Enceladus? I call Gliese 581 after that. I want to know for sure if the fourth planet (the setting of our story Yuva) is inhabitable or not already!

These are exciting times we live in, aren’t they?

The News From Saturn

Saturn has certainly been seen in the news a lot as of late. And you have the Cassini space probe, which was deployed from Earth back in 1997, to thank for all of that. Having completed the first leg of its mission back in 2008, its mission was extended to 2010, when most of the new photos and startling discoveries that are now being announced were made. Now, the healthy spacecraft is seeking to make exciting new discoveries in a second extended mission called the Cassini Solstice Mission.

But alas, the news! First, there was the announcement back in February that Saturn’s two largest moons – Titan and Rhea – were captured together in the same photo by the Cassini space probe. Considering that Saturn has 66 moons and Cassini was flying past at the time, this was no small accomplishment! What’s more, Titan’s atmosphere, which is fully developed (the only Saturnine moon to have this) was captured perfectly the shot.

But the news didn’t stop there. Shortly thereafter, in March to be specific, a report published in the Geophysical Research Letters announced that a thin layer of oxygen was discovered around Saturn’s moon of Dione. Once again, this discovery was made by the Cassini space probe as it passed by this other satellite of Saturn’s two years ago. This finding is proving to be quite the exciting one within the astronomical community.

Shortly after that, NASA announced that the moon of Enceladus did indeed have its own ocean. Named the Enceladan Ocean, this natural body of water has been known about for some time, but what is now known is the water contains carbon dioxide, carbon monoxide, potassium salts and other organic materials. On top of that, it is now understood that it is situated above some volcanic jets, which means the water is most likely warm. Warm water, combined with organic minerals, makes the Enceladan Ocean a good candidate for life!

And then, in late July, images released by NASA showed that Cassini also caught a glimpse of a thunderstorm happening on Saturn’s surface. As all residents of Earth will surely agree, a thunderstorm is an impressive sight to behold. Especially when it’s seen happening on another planet! Apparently, what made this sighting most impressive was that it was visible on Saturn’s day side – aka. in broad daylight – from a range of 4.5 million km (2 million miles). That’s one humungous light show!

And less than a week ago, more information emerged as a result of the Cassini space probe, this time in relation to Saturn’s moon of Iapetus. After getting a good glimpse of the moon, scientists at NASA have determined that it is home to the largest ice avalanches in the Solar System, and is rivaled only by Mars. Take that Mount Everest! You too Olympus Mons!

Already, scientists had Iapetus pegged as the most intriguing moon in the Solar System. For starters, it has a Ying-Yang color pattern, looks like an inverted Death Star (check that image, no Photoshopping!), and has a long ridge running almost perfectly along Iapetus’ equator, a feature which earned it the nickname “the walnut moon”. I guess it wasn’t happy with just that, it also wanted to be the most dangerous place to downhill ski!

And you thought Jupiter did some badass things. Well, it does. But judging from all these findings, Saturn is going to be a pretty happening place someday. I can envision settlements on Titan, skiing on Iapetus, and terraforming on Dione. And for those who like to sight-see, there will be shuttle services that take you to the dark side of Saturn to witness the light show from space. Ooooh, I got goose bumps!
