The Huygens space probe, which was attached to the Cassini spacecraft that has been orbiting Saturn since 2004, landed on the planet’s biggest moon, Titan, in 2005.
Huygens travelled with Cassini, which departed Earth in October 1997, before separating once the rockets reached the Saturn-system and landed on the Moon early the following year.
Before the probe left Earth, scientists did not have much knowledge regarding Titan.
However, over a decade since its arrival, scientists now recognise Titan as one of the leading contenders to find life elsewhere in the solar system.
Huygens approaches Titan
So far, Titan is the only celestial body in the solar system, aside from Earth, that homes stable bodies of liquid – although its oceans are made up of ethane and methane and not water.
Nasa’s Jet Propulsion Laboratory said in a statement: "The Huygens descent and landing represented a major breakthrough in our exploration of Titan as well as the first soft landing on an outer-planet moon.
"It completely changed our understanding of this haze-covered ocean world.”

NASA's Cassani mission have released these amazing unseen photos of Saturn and it's many moons. These incredible images show close up photographs of Saturn and and it's orbiting moons taken from approximately 1.4 million miles away.

Carolyn Porco, Cassini imaging team lead, said: "The Huygens images were everything our images from orbit were not.
"Instead of hazy, sinuous features that we could only guess were streams and drainage channels, here was incontrovertible evidence [that] at some point in Titan's history — and perhaps even now — there were flowing liquid hydrocarbons on the surface.
Saturn, as seen from Titan
"Huygens' images became a Rosetta Stone for helping us interpret out subsequent findings on Titan.”
The video that was released by Nasa shows a series of images from Huygens’ descent that have been merged and animated to illustrate the entire process.
Cassini has recently began its final missions around Saturn.
Cassini has entered its final stage of its Saturn mission
The new stage in Cassini’s life will see it yo-yo to the edge of Saturn’s outer rings 20 times over the next five months, before plunging towards the planet itself.
Each time the spaceship will hold its position for a week.
When Cassini is done with its bold manoeuvres, it will intentionally destroy itself in Saturn’s atmosphere.
