How Cassini's haunting Grand Finale unlocked Saturn’s secretsTEHRAN, Young Journalists Club (YJC) -On September 15, 2017 the NASA and ESA Cassini-Huygens mission to Saturn ended when the probe was incinerated in the gas giant’s atmosphere. RT.com looks back at Cassini’s epic Grand Finale plunge prior to its fiery death. 

Cassini blasted off from Earth on October 15, 1997. After a near-seven-year journey, it arrived at its destination, some 93 million miles from home. Yet it wasn’t until April 2017 that it began its final descent into Saturn. The Grand Finale began on April 26, when the intrepid probe went where nothing from Earth had gone before, dramatically diving between the planet and its vast ring system a total of 22 times.

Using its dish-shaped antenna as a shield against potentially-damaging space particles Cassini plunged through the gap.

As Cassini crossed Saturn’s ring plane it collected data using its Radio and Plasma Wave Science instrument which is so sensitive it can detect the impact of minute dust particles touching off the spacecraft.

On April 27, NASA released stunning images of a giant hurricane on Saturn and the closest-ever photos of the planet’s atmosphere.

Then in early May, the space agency released an incredible movie of the probe’s first dive. It depicts the observations made as the spacecraft passed southward over Saturn on April 26.
