Cassini

Giovanni Cassini was an Italian astronomer, most famous for first discovering four of Saturn's moons. Over 300 years later the unmanned spacecraft Cassini-Huygens was launched and began its mission to Saturn. After entering orbit on 1 July 2004 on the 25 December the Huygens lander separated from the Cassini orbiter and landed on Titan, Saturn's largest moon. Twelve years after their arrival both continue to complete missions, until it finally completed a controlled descent into the planet's atmosphere on 15 September 2017.
