Is Titan Moon Habitable

Saturn's largest moon Titan is one of several candidates for possible future colonization of the outer Solar System, though protection against extreme cold is a major consideration. According to Cassini data from 2008, Titan has hundreds of times more liquid hydrocarbons than all the known oil and natural gas reserves on Earth. These hydrocarbons rain from the sky and collect in vast deposits that form lakes and dunes. Ralph Lorenz, who leads the study of Titan based on radar data from Cassini. Several hundred lakes and seas have been observed, with several dozen estimated to contain more hydrocarbon liquid than Earth's oil and gas reserves. The dark dunes that run along the equator contain a volume of organics several hundred times larger than Earth's coal reserves. Radar images obtained on July 21, 2006 appear to show lakes of liquid hydrocarbon (such as methane and ethane) in Titan's northern latitudes. This is the first discovery of currently existing lakes beyond Earth. The lakes range in size from about a kilometer in width to one hundred kilometers across. On March 13, 2007, the Jet Propulsion Laboratory announced that it found strong evidence of seas of methane and ethane in the northern hemisphere.

At least one of these is larger than any of the Great Lakes in North America. The American aerospace engineer and author Robert Zubrin identified Saturn as the most important and valuable of the four gas giants in the Solar System, because of its relative proximity, low radiation, and excellent system of moons. He also named Titan as the most important moon on which to establish a base to develop the resources of the Saturn system. The atmosphere contains plentiful nitrogen and methane. Additionally, strong evidence indicates that liquid methane exists on the surface. Evidence also indicates the presence of liquid water and ammonia under the surface, which are delivered to the surface by volcanic activity. While this water can be used to generate breathable oxygen, more is blown into Titan's atmosphere from the geysers on the icy moon of Enceladus (also a moon of Saturn), as they start as water molecules and evolve into oxygen and hydrogen. Nitrogen is ideal to add buffer gas partial pressure to breathable air (it forms about 78% of Earth's atmosphere). Nitrogen, methane and ammonia can all be used to produce fertilizer for growing food. In situ energy resources on Titan for use by future humans include chemical, nuclear, wind, solar and hydropower. Electrical power could be produced using chemical power plants adding hydrogen to acetylene (ie Kraken Mare where the tidal pull of Saturn causes up to a meter of tidal change each Titan day.

Titan, more so than on Mars.

Nuclear and solar power might also be feasible. Titan has a surface gravity of 0.138 g, slightly less than the Moon. Titan, more so than on Mars. These effects are still an active field of study. They can include symptoms such as loss of bone density, loss of muscle density, and a weakened immune system. Astronauts in Earth orbit have remained in microgravity for up to a year or more at a time. Effective countermeasures for the negative effects of low gravity are well-established, particularly an aggressive regimen of daily physical exercise or weighted clothing. The variation in the negative effects of low gravity as a function of different levels of low gravity are not known, since all research in this area is restricted to humans in zero gravity. The same goes for the potential effects of low gravity on fetal and pediatric development. It has been hypothesized that children born and raised in low gravity such as on Titan would not be well adapted for life under the higher gravity of Earth. The very high ratio of atmospheric density to surface gravity also greatly reduces the wingspan needed for an aircraft to maintain lift, so much so that a human would be able to strap on wings and easily fly through Titan's atmosphere while wearing a sort of spacesuit that could be manufactured with today's technology.

Another theoretically possible means to become airborne on Titan would be to use a hot air balloon-like vehicle filled with an Earth-like atmosphere at Earth-like temperatures (because oxygen is only slightly denser than nitrogen, the atmosphere in a habitat on Titan would be about one third as dense as the surrounding atmosphere), although such a vehicle would need a skin able to keep the extreme cold out in spite of the light weight required. Due to Titan's extremely low temperatures, heating of any flight-bound vehicle becomes a key obstacle.

As of June 10, 2021, eight volumes have been published as part of the Progressive series.

Sword Art Online is a Japanese light novel series written by Reki Kawahara with accompanying illustrations drawn by abec. The series takes place in the near-future and focuses on various virtual reality MMORPG worlds. ASCII Media Works began publishing the novels on April 10, 2009 under their Dengeki Bunko imprint. Russia. With more than 16 million copies in print worldwide, there are future plans for publications in Germany, Italy, Austria, Switzerland, Vietnam and others. Kawahara also began writing a parallel series of light novels titled Sword Art Online: Progressive, a spin-off that focuses on the clearing of Aincrad, unlike the Aincrad stories of the main series. As of June 10, 2021, eight volumes have been published as part of the Progressive series. In addition to the original storyline of Sword Art Online and Sword Art Online: Progressive, Kawahara has also written and published Sword Art Online side stories. Accel World, have been sold at Comitia, Dengeki Bunko's Fair and have come along with the limited edition Blu-Ray/DVD Sword Art Online compilation volumes.

Before Sword Art Online was published, Kawahara had posted Sword Art Online novels on his website and there are still a few side stories on Sword Art Online, although the original novels have been removed. In addition, Kawahara has published a side story of Sword Art Online in one of his other works, Accel World. In the tenth volume of Accel World, there is a chapter where it depicts a cross over between Sword Art Online and Accel World. Several of the side stories that he has released are in a collection called the Sword Art Online Material Edition, sold at the Comitia dōjinshi-selling event, which range from novels to manga. However, all of the art in the Material Editions is drawn by Kawahara himself. Aside from the light novels written by Kawahara, there are also two spin-offs written by other authors with supervision by him. The first one is Sword Art Online Alternative: Gun Gale Online series written by Keiichi Sigsawa and illustrated by Kouhaku Kuroboshi, while the other is Sword Art Online Alternative: Clover's Regret, written by Watase Souichirou and illustrated by Ginta. While both of these series take place in the same world as the main series written by Kawahara, they each feature different characters as the focus compared to the main series.
