Habitability. Robert Zubrin has pointed out that
Thus, Titan could potentially harbor environments with conditions suitable for life—meaning both life as we know it (in the subsurface ocean) and life as we don't know it (in the hydrocarbon liquid on the surface).
It has been speculated that life could exist in the liquid methane and ethane that form rivers and lakes on Titan's surface, just as organisms on Earth live in water. Such hypothetical creatures would take in H2 in place of O2, react it with acetylene instead of glucose, and produce methane instead of carbon dioxide.
After a descent lasting two hours and 27 minutes, the Huygens probe successfully landed on Titan on Jan. 14, 2005. The probe survived 72 minutes on Titan's surface.
On January 14, 2005, humans successfully achieved an incredible feat unsurpassed to date. The European Space Agency's (ESA) Huygens probe, a metal pie-plate looking device 1.3 metres in diameter, parachuted down onto Titan, the largest of Saturn's moons, and landed unscathed on its surface.
is based on water. And while the atmo- spheric pressure on Titan is moderate—1.5 times the pressure of Earth's atmosphere, about what divers experience 15 feet under- water—there is no oxygen in it.
If a Pure Titan gained the power of the Titans, that Titan would return to being a human. After Ymir's decision to relinquish her power, all the surviving Titans collectively lost their power and reverted back to normal humans.
To break it down, only Enceladus and Titan appear to be viable candidates for terraforming. However, in both cases, the process of turning them into habitable worlds where human beings could exist without the need for pressurized structures or protective suits would be a long and costly one.
Here's Where It Will Land. Smothered in a hazy atmosphere that hides shallow lakes of liquid hydrocarbons, Titan is one weird world we're dying to look at up close. Which is why NASA is preparing to launch a robotic rotocraft to scope out the scenery in 2027.
Titan has a surface gravity of 0.138 g, slightly less than the Moon. Managing long-term effects of low gravity on human health would therefore be a significant issue for long-term occupation of Titan, more so than on Mars. These effects are still an active field of study.
Titan is not a pleasant place for life. It is far too cold for liquid water to exist, and all known forms of life need liquid water. Titan's surface is -180°C.
In the case of Europa, it is believed to have a subsurface ocean of liquid water, but this ocean is covered by a layer of ice and is not accessible. Titan, on the other hand, has lakes and seas of liquid methane and ethane on its surface, but these liquids are not drinkable for humans.
In addition to H2, McKay and Smith [4] suggested that methane-based life on Titan could consume acetylene and ethane. There seems to be evidence for depletion of acetylene and ethane on Titan.
Titan's subsurface ocean might be a place where life as we know it could exist, while its surface lakes and seas of liquid hydrocarbons might be places to look for life as we don't know it.
It is cold on Titan (surface temperature of about -290 degrees F). And people would need to wear respirators to breathe oxygen, since the atmosphere is mostly nitrogen. The light on Titan is a little dim, like just after a sunset here on Earth, due to the haze particles in the thick atmosphere.
Saturn's orange moon Titan has hundreds of times more liquid hydrocarbons than all the known oil and natural gas reserves on Earth, according to new Cassini data. The hydrocarbons rain from the sky, collecting in vast deposits that form lakes and dunes.
Dragonfly is expected to launch in June 2027, and will take seven years to reach Titan, arriving by 2034. The spacecraft will perform a gravity assist flyby of Venus, and three passes by Earth to gain additional velocity.
When will the mission launch how long will it take to get to Titan? This mission would last about 14 years. It would take roughly seven years to get there, and then the same to get back, though well-timed gravity-assists either on the way there or back could reduce the total flight time to just 10 years.
The day cycle on Titan lasts 15.9 Earth days, which is how long it takes Titan to orbit Saturn. Titan is tidally locked, so the same part of Titan always faces Saturn, and there is no separate "month" cycle.
While Venus, Earth, Mars, and even the Moon have been studied in relation to the subject, Mars is usually considered to be the most likely candidate for terraforming.
The legend of the first Titan, Ymir Fritz, details how the Titans' founder lived for a mere 13 years, and thereafter, no Titan could surpass that limit.
With Titan's surface sculpted by methane and ethane, which no other world in the solar system aside from Earth has, it should have no problem producing tobacco plants.
Eren certainly feels pain each time he chomps down on his hand to change into a Titan.
This Titan was the first Pure Titan shown to speak words with meaning. The second was Ms. Springer. This Titan was the only common Titan seen that displayed a range of emotions.
Before the operation to retake Wall Maria Keith Shadis tells Eren that he first met Grisha about 20 years ago. At this point the attack on Wall Maria which coincided with Grisha's death happened 5 years ago. So Grisha had in fact been inside the Walls for 20-5 = 15 years!
