The Final Fall of the Angel Cassini (feat. Saturn)

Later this morning, the space probe Cassini will bring its 20 year, 4.5 billion km, multi-planet and moon mission to a final conclusion as operators on Earth dive it into Saturn's atmosphere for a final farewell. Cassini is one of the most successful space missions ever undertaken, perhaps one of the most successful scientific collaborations in human history. To quote the NASA Jet Propulsion lab website (saturn.jpl.nasa.gov/mission/ab...mission/summary), today, Sept. 15, 2017, "the spacecraft will make its final approach to the giant planet Saturn. But this encounter will be like no other. This time, Cassini will dive into the planet’s atmosphere, sending science data for as long as its small thrusters can keep the spacecraft’s antenna pointed at Earth. Soon after, Cassini will burn up and disintegrate like a meteor.

To its very end, Cassini is a mission of thrilling exploration. Launched on Oct. 15, 1997, the mission entered orbit around Saturn on June 30, 2004 (PDT), carrying the European Huygens probe. After its four-year prime mission, Cassini’s tour was extended twice. Its key discoveries have included the global ocean with indications of hydrothermal activity within Enceladus, and liquid methane seas on Titan.
And although the spacecraft may be gone after the finale, its enormous collection of data about Saturn – the giant planet itself, its magnetosphere, rings and moons — will continue to yield new discoveries for decades."

Farewell Cassini, you Angel of Science!
