After traveling for 13 years on due course through space to Saturn and its moons, NASA’s Cassini spacecraft plunged into Saturn’s atmosphere on Friday, Sept. 15, drawing an end to its long journey.

The prime mission began in 2004, and was a collaboration between NASA, the European Space Agency (ESA), and the Italian Space Agency (ASI). The Huygens probe traveled into space with the Cassini spacecraft, but it landed on the surface of Titan in 2005, becoming the first probe to land in the outer solar system and on a moon other than our own.

The seven-year mission extension, beginning in 2010, was intended for Cassini to further explore Saturn, its rings and its moons. The initial launch took place on Oct. 15, 1997, with the spacecraft entering into orbit around Saturn on June 30, 2004.

Throughout the course of its entire mission, Cassini’s exploration was extended twice. Cassini-Huygen’s initial four-year tour of the Saturn system was completed in 2008. The following two-year extension mission, named the Cassini Equinox Mission, was a series of successful orbits around the planet and a number of flybys of the planet’s multiple moons. The second mission extension began in 2010, known as the Cassini Solstice Mission.

Over the course of last five months, the spacecraft completed a series of 22 dives between the planet and its rings, which began on April 22 and ended on Sept. 15, also known as the “Grand Finale”. Each dive lasted about six and a half days, with Cassini diving at tens of thousands of miles per hour for each one. During Cassini’s final dive before its final approach Saturn, also called the “Goodbye Kiss,” the spacecraft was able to get within 75,00 miles of Saturn’s largest moon, Titan, whose gravity slightly changed the projectile’s trajectory and made sure that.

As the fourth spacecraft to extensively travel into space solely dedicated to study and send back in-depth information on Saturn and its system of rings and moon and the first one to enter into the planet’s orbit, Cassini made several discoveries about the planet as well as its moons, including the global ocean within Enceladus, one of Saturn’s moons, as well as the liquid methane seas on Titan.
