Largest Moon of Saturn. Has an atmosphere containing mostly Nitrogen and
1 gram on Earth would weigh 0.14g on Titan. Only know moon in our solar system to have a dense
16 Earth day orbital period of Saturn.

Titan is the only known moon in the solar system to
have an atmosphere.
Titan’s atmosphere is made up of about 98.4% nitrogen,
with the remaining 1.6% made mostly of methane and hydrogen.
Titan’s atmosphere is around 50% thicker than Earth’s. As well as this, the atmosphere is very spread out due
to the low gravity on Titan.
Due to both of these factors, it would be possible to fly
wings.
As well as an atmosphere, Titan has oceans of methane
Just like Earth, these oceans carve out the landscape by
eroding the rock.
On Earth, methane is usually only found in a gaseous
form.
As it is so cold on Titan, methane can exist in solid,
liquid and gaseous form, a bit like Earth’s water cycle.
It is thought that a liquid water ocean could exist
beneath the methane (with the methane acting as an insulator to keep it in liquid form).
Titan is extremely cold as it is over 1 billion km from the sun.
This means that it is covered with liquid methane; a chemical which on Earth, is not stable enough to form a liquid.
The liquid methane shapes the beautiful landscapes you see
below.
Liquid methane has its own cycle. It rains, forms clouds and
flows just like water. However, the rain droplets are twice the size of those on Earth.
Reaching Titan is a difficult task A mission must have many things to work: Habitation for the surface. Transport with enough habitation and fuel. Working mechanisms to escape the highly
Transport and habitation for the return as well

For this mission we are using… …10 rockets
The First six are all heavy cargo lifters. They transport the two habitation modules (HAB) and the Titan Assent Vehicle (TAV) as well as the three propulsion stages for each.

The next three launches are also heavy cargo lifters. These carry the two propulsion stages for the crew transport habitat (CTH). Each of the segments dock in Low Earth Orbit (LEO) to form the titan transport vehicle Aeris (Latin for air). Aeris I

Vehicle. After 2 minutes the solid rocket boosters (SRB) separate.
After a further 6 minutes, the core stage is jettisoned along with the escape tower and panel fairings.
The third stage then powers the Orion Capsule to LEO. The third stage is jettisoned and Orion opens its solar panels.
Orion Capsule
The Orion Spacecraft docks with Aeris and the crew get on-board One crew member stays behind and takes the Orion Capsule towards the ISS (International Space Station). Aeris then fires its engines and leaves LEO for Titan.

It would be impossible to fire an engine all the way to Saturn as it would require too much fuel. Instead, Aeris will fire its rockets to Mars. When it reaches the red planet, it will use the gravity to slingshot around to Jupiter. Jupiter will then give the big push that is needed to reach Saturn The first flight will launch on the 14th October 2020 as that is when the Planets next come into alignment.
As Aeris arrives at Titan, three landing craft will separate and land, each carrying 10 crew members. These craft are called Aura I, II & III ( Greek Titaness of the breeze) Friction against the base of the space craft glows as Aura experiences hypersonic aero assisted deceleration. This slows the space craft from 30,000 km/h to around 1,000 km/h
Despite the deceleration from the atmosphere, Aura is still traveling at over 1,000 km/hour! T wo drogue chutes are first deployed. This slows Aura to 20m/s. 60 seconds later, the three main parachutes will deploy, slowing the space craft down to a steady 6m/s (15mph) 30 seconds after that, floating landing gear deploys and Aura lands

There are many Sports that can be done on Titan.
Swimming – Since the gravity is so low, it is
Hiking –There are plenty of mountains to climb.
Flying – Due to Titan’s atmosphere being 50%
Getting off Titan is difficult as it has a highly flammable atmosphere meaning rockets cannot be used. Instead, the TAV uses a hydrogen balloon which lifts the vehicle most of the way. It is only when the atmosphere has become thin enough that it will not catch fire that engines will be fired. This will power the TAV into orbit where it docks with Aeris. The TAV is then jettisoned before Aeris leaves Titan.
Not T
Aeris will slingshot around Saturn on a straight course for Earth. It will arrive at Earth on 30th August 2023, almost three years after leaving
As Aeris is captured into LEO, the Orion space craft will dock and pick up the crew. Orion will then jettison its service module and enter Earth’s atmosphere.
Two drogue chutes will deploy for 23 seconds slowing the spacecraft to less than mach 1. The main chutes will then open in stages. 3%, 40% & 100%. Orion will splash down in the Pacific
