The Nautilus is the fictional submarine captained by Nemo featured in Jules Verne's novels Twenty Thousand Leagues Under the Sea (1870) and The Mysterious Island (1874). Verne named the Nautilus after Robert Fulton's real-life submarine Nautilus (1800)[citation needed]. Three years before writing his novel, Jules Verne also studied a model of the newly developed French Navy submarine Plongeur at the 1867 Exposition Universelle, which inspired him for his definition of the Nautilus.[1][better source needed]

A tachyon /ˈtæki.ɒn/ or tachyonic particle is a hypothetical particle that always moves faster than light. The word comes from the Greek: ταχύς or tachys, meaning "swift, quick, fast, rapid", and was coined in 1967 by Gerald Feinberg.[1] The complementary particle types are called luxon (always moving at the speed of light) and bradyon (always moving slower than light), which both exist. The possibility of particles moving faster than light was first proposed by Bilaniuk, Deshpande, and George Sudarshan in 1962, although the term they used for it was "meta-particle".[2]

Description


Titan is unique in the outer solar system in that it is the only one of the bodies outside the Earth with liquid lakes and seas on its surface. The Titanian seas, however, are not composed of water, like Earth’s seas, but are seas of liquid hydrocarbons. What lies beneath the surface of Titan’s seas? We propose to develop a conceptual design of a submersible autonomous vehicle (submarine) to explore extraterrestrial seas. Specifically, to send a submarine to Titan’s largest northern sea, Kraken Mare. This craft will autonomously carry out detailed scientific investigations under the surface of Kraken Mare, providing unprecedented knowledge of an extraterrestrial sea and expanding NASA’s existing capabilities in planetary exploration to include in situ nautical operations.

Sprawling over some 1000 km, with depths estimated at 300 m, Kraken Mare is comparable in size to the Great Lakes and represents an opportunity for an unprecedented planetary exploration mission. This mission would be a logical follow-on to a Titan surface mission such as TiME (Titan Mare Explorer) or even a component of a flagship mission of multiple vehicles. The mission concept we propose to study will investigate a full spectrum of oceanographic phenomena: chemical composition of the liquid, surface and subsurface currents, mixing and layering in the “water” column, tides, wind and waves, bathymetry, and bottom features and composition. Measurements of all these aspects of Titan’s hydrocarbon ocean environment can only be made through focused in situ exploration with a well-instrumented craft. This investigation represents a significant advancement in our understanding of the history and evolution of organic compounds in the solar system, and hence a critical step along the path to understanding the evolution of life here on Earth and potential life elsewhere in the galaxy.

While concepts of exploring extraterrestrial oceans, specifically Titan’s, have been proposed in the past they have centered on simple suspended probes or ‘diving bells’ (Lorenz, 2009, Epperly et al., 2010.) Titan Submarine, or Titan Sub for short, will be a fully autonomous, highly capable science craft that will allow a complete exploration of what exists beneath the waves on another world. As such no one has yet envisioned what such a craft might look like, how it would operate or if it could be built; this is the conceptual mission design work we propose with Titan Sub.

The Titan Sub addresses NASA’s strategic goals 2, 3, and 6 by exploring the Titan environ-ment which could hold clues to how earth and life formed, it will create new technologies in the form of a semi-autonomous planetary submersible which could be extended to other planetary oceans, and would capture the imaginations of educators and students by sharing with them exploration of a completely new environment on a foreign world.

Titan Sub will also address the NASA technology areas of Space Power and Energy Storage, Robotics and Autonomous Systems, Communications and Navigation Systems, Science Instruments and Sensors, Materials, and Thermal Management Systems.

By addressing the challenges of autonomous submersible exploration in a cold outer solar system environment, Titan Sub serves as a pathfinder for even more exotic future exploration of the subsurface water oceans of Europa etc.

NASA proposes submarine mission to Saturn’s moon Titan

K6dmF6moZcQ

Published on 13 Feb 2015


NASA is planning to send a submarine to Saturn’s largest moon by 2040 to
study Titan’s hydrocarbon oceans. Titan is the only celestial body in the solar
system other than Earth that is known to host liquid lakes and seas on its surface.

Titan’s atmosphere is a mix of methane, nitrogen, and argon, and its surface
has liquid methane oceans and lakes. Atmospheric pressure is 50 percent
higher than Earth at sea level.

The submarine will be carried to Titan by a spacecraft similar to the X-37
Orbital Test Vehicle. The spacecraft would decelerate on contact with Titan’s
dense atmosphere and glide into Titan’s Kraken Mare, where the sub would
be ejected from the spacecraft.

The submarine’s radiothermal Sterling generator can propel the craft at about
4 kmph and generates heat to keep the craft from freezing in the liquid methane sea.

The submarine will measure the alien sea’s chemistry, currents and tides, as
well as hunt for evidence of organic life. At surface level the craft is able to
transmit data directly back to Earth via its antenna.

NASA hopes that by studying Titan’s Kraken Mare, the mission could reveal
whether environmental conditions hospitable to life may be found on planets
and moons outside our solar system.

Nasa wants to send a SUBMARINE to space in 2040: Agency reveals plans for a craft to explore Titan’s hydrocarbon oceans
Submarine will head to the largest northern sea, dubbed Kraken Mare, on Saturn's biggest satellite
It would weigh around one tonne (2,200 lb) and travel at one metre per second (3.6 km/h, 2.2 mph)
With sea temperature of -290 °F (-179 °C), a radiothermal Sterling generator will prevent it from freezing
Mission will look for traces of compounds that could give a better understanding of how life began

Sounds like Orson Scott Card's book Titan. Pretty cool book

[ghostrider]

I would wager NASA has already explored the waters of Titan ... now they wag the dog to hide their secret technology ...

[toppy]

I love Jules Verne and his novels, I grew up reading them all the time ever and ever again many times.

Heehee!

my grandma had an abridged version of 20,000 leagues, i read it as a kid,
not sure if i ever did pick up the original -- omg :(


but the scene with the giant squid, eek!
*thinks of Kraken from golden sun :) *

Whether there is life on Titan, the largest moon of Saturn, is at present an open question and a topic of scientific assessment and research. Titan is far colder than Earth, and its surface seems to lack liquid water; factors which have led some scientists to consider life there unlikely. On the other hand, some scientists speculate on Titan's suitability to sustain some form of non-water-based life.

In June 2010, scientists analysing data from the Cassini–Huygens mission reported anomalies in the atmosphere near the surface which could be consistent with the presence of methane-producing organisms, but may alternatively be due to non-living chemical or meteorological processes.[1] The Cassini–Huygens mission was not equipped to provide direct evidence for biological activity or complex organic compounds.



Methane (CH4) is a simple hydrocarbon: that is, a compound of two of the most common elements in the cosmos, hydrogen and carbon. It has a cosmic abundance comparable with ammonia.[41] Hydrocarbons could act as a solvent over a wide range of temperatures, but would lack polarity. Isaac Asimov, the biochemist and science fiction writer, suggested in 1981 that poly-lipids could form a substitute for proteins in a non-polar solvent such as methane.[41] Lakes composed of a mixture of hydrocarbons, including methane and ethane, have been detected on Titan by the Cassini spacecraft.



There is debate about the effectiveness of methane and other hydrocarbons as a medium for life compared to water or ammonia.[47] Water is a stronger solvent than the hydrocarbons, enabling easier transport of substances in a cell.[48] However, water is also more chemically reactive, and can break down large organic molecules through hydrolysis.[47] A life-form whose solvent was a hydrocarbon would not face the threat of its biomolecules being destroyed in this way.[47] Also, the water molecule's tendency to form strong hydrogen bonds can interfere with internal hydrogen bonding in complex organic molecules.[40] Life with a hydrocarbon solvent could make more use of hydrogen bonds within its biomolecules.[47] Moreover, the strength of hydrogen bonds within biomolecules would be appropriate to a low-temperature biochemistry.[47]

Astrobiologist Chris McKay has argued, on thermodynamic grounds, that if life does exist on Titan's surface, using hydrocarbons as a solvent, it is likely also to use the more complex hydrocarbons as an energy source by reacting them with hydrogen, reducing ethane and acetylene to methane.[49] Possible evidence for this form of life on Titan was identified in 2010 by Darrell Strobel of Johns Hopkins University; a greater abundance of molecular hydrogen in the upper atmospheric layers of Titan compared to the lower layers, arguing for a downward diffusion at a rate of roughly 1025 molecules per second and disappearance of hydrogen near Titan's surface. As Strobel noted, his findings were in line with the effects Chris McKay had predicted if methanogenic life-forms were present.[48][49][50] The same year, another study showed low levels of acetylene on Titan's surface, which were interpreted by Chris McKay as consistent with the hypothesis of organisms reducing acetylene to methane.[48] While restating the biological hypothesis, McKay cautioned that other explanations for the hydrogen and acetylene findings are to be considered more likely: the possibilities of yet unidentified physical or chemical processes (e.g. a non-living surface catalyst enabling acetylene to react with hydrogen), or flaws in the current models of material flow.[51] He noted that even a non-biological catalyst effective at 95 K would in itself be a startling discovery.[51]

(Although Mars is not known to have liquid methane, methane gas in its atmosphere is of astrobiological interest as a substance that might be produced by living organisms.[52] See Life on Mars.)

The Creation of Adam is a fresco painting by Michelangelo, which forms part of the Sistine Chapel's ceiling, painted circa 1511–1512. It illustrates the Biblical creation narrative from the Book of Genesis in which God breathes life into Adam, the first man. The fresco is part of a complex iconographic scheme and is chronologically the fourth in the series of panels depicting episodes from Genesis. It is the most well-known of the Sistine Chapel fresco panels, and its fame as a piece of art is rivaled only by the Mona Lisa by Leonardo da Vinci.

The image of the near-touching hands of God and Adam has become iconic of humanity and has been reproduced in countless imitations and parodies. Leonardo da Vinci's Last Supper and Michelangelo's Creation of Adam are the most replicated religious paintings of all time.



if there is life on Titan we must ensure that it is handled with a delicate touch,
not like what happened here
