Get ready for an adventure! Titan, Saturn's largest moon, is a
frosty wonderland with mountains, rivers, lakes, oceans, and
clouds that resemble Earth. And guess what? Despite the
frigid conditions, Titan holds the potential for life to thrive,
making it a truly extraordinary destination!
A unique moon

History
Titan was discovered on March 25, 1655 by Dutch astronomer Christiaan Huygens. In 1944,
Dutch-American astronomer Gerard Kuiper, by using the sunlight reflected off of Titan in a
spectrometer where he detected methane, discovered that Titan has an atmosphere.
METHANE LAKES !
Titan's surface is relatively smooth, with fewer impact craters compared to other moons
or rocky bodies in the solar system. The presence of liquids on the surface, along with
geological processes, helps to erase impact craters over time.
Due to the extremely cold temperatures, there are methane and methane lakes and
rivers all across the surface of Titan.
Titan is the only moon in our solar system with a thick atmosphere and the
only world with standing liquid besides earth. This combined with the Earthlike cycle of methane evaporating condensing and falling much akin to the
water cycle we have on earth makes Titan a very interesting celestial body.

Titan’s size & position
Titan is Saturn’s largest moon and the second largest moon in our solar system. It has a
diameter measuring about 5,149.4 km. The moon is about 1.2 million km from Saturn, and is
about 1.4 billion km from the Sun.
Titan has a “methane” cycle very similar to Earth’s water cycle. The sunlight breaks
down the methane in the atmosphere, causing methane clouds to form and rains that
ow into rivers, which then evaporate back into the atmosphere. However, this is not
all there is to the methane cycle, as it is a bit more complicated than Earth’s water
cycle.
Atmosphere

Titan is the only moon in our solar
system with an atmosphere. Its
atmosphere is composed of ~95%
nitrogen and ~5% methane,
with some carbon compounds
mixed in. The atmosphere extends
almost 600 km into space.
The methane in Titan’s atmosphere
is constantly being broken down by
the sunlight, so where is this source
of methane coming from? Scientists
are predicting that there are
cryovolcanoes that release water and
ice instead of lava, but they are
unsure.
Prebiotic Chemistry & Potential for Life
Titan, the organic wonderland! This celestial paradise brims with possibilities
when it comes to prebiotic chemistry and the potential for vibrant life. Picture
this: methane lakes and an atmosphere dominated by nitrogen, crafting an
extraordinary backdrop for the birth of complex organic molecules.

Human Interaction
Titan, Saturn's largest moon, has intrigued NASA for years. In 1997, the Cassini spacecraft began a mission to study Saturn and its moons.
The Huygens Probe, carried by Cassini, was designed to investigate Titan's atmosphere. On January 13th, 2005, the probe successfully
landed on Titan's surface, becoming the first man-made object to reach an outer solar system object. Cassini completed its mission in
2017, conducting 127 fly-bys of Titan and capturing extensive data. The findings included methane oceans, lakes, and towering peaks
reaching heights of 10,984 feet. Titan's resemblance to early Earth has fueled scientists' desire to explore it further. NASA's upcoming
Dragonfly mission, scheduled for launch in 2026, aims to search for signs of life on Titan using a drone. Until then, this represents our
current understanding and exploration of Titan.
