What did the Cassini mission discover?
Cassini’s long mission enabled us to observe weather and seasonal changes on another planet. Cassini revealed Saturn’s moons to be unique worlds with their own stories to tell. Cassini showed us the complexity of Saturn’s rings and the dramatic processes operating within them.
WHO launched Cassini?
NASA
A joint endeavor of NASA, the European Space Agency, or ESA, and the Italian Space Agency, Cassini launched in 1997 along with ESA’s Huygens probe. The spacecraft contributed to studies of Jupiter for six months in 2000 before reaching its destination, Saturn, in 2004 and starting a string of flybys of Saturn’s moons.
What was the purpose of the Cassini-Huygens mission?
The objectives of the Cassini-Huygens mission are to analyze the composition and atmosphere of Saturn, investigate Saturn’s rings and several of its moons, and study the planet’s magnetosphere – the region of space that’s influenced by Saturn’s magnetic field.
Where is Cassini-Huygens now?
All were taken when Cassini was about 394,000 miles (634,000 kilometers) from Saturn, NASA officials said. The spacecraft burned up in a patch of Saturn sky at 9.4 degrees north latitude and 53 degrees west longitude.
Why did NASA destroy Cassini?
The mission ended on September 15, 2017, when Cassini’s trajectory took it into Saturn’s upper atmosphere and it burned up in order to prevent any risk of contaminating Saturn’s moons, which might have offered habitable environments to stowaway terrestrial microbes on the spacecraft.
Who first saw Saturn?
astronomer Galileo Galilei
Learn more about the sixth planet in our solar system and its rings. Saturn was the most distant of the five planets known to the ancients. In 1610, Italian astronomer Galileo Galilei was the first to gaze at Saturn through a telescope. To his surprise, he saw a pair of objects on either side of the planet.
Is Cassini still alive?
Cassini Spacecraft Ends Its Historic Exploration of Saturn NASA’s Cassini spacecraft made its final approach to Saturn and dove into the planet’s atmosphere on Friday, Sept. 15, 2017. Loss of contact with the Cassini spacecraft took place on Sept. 15 at 7:55:46 a.m. EDT (4:55:46 a.m. PDT).
How long did Huygens last on Titan?
Plunging into Titan’s atmosphere, the probe survived the hazardous 2 hour 27 minute descent to touch down safely on Titan’s frozen surface. Huygens continued to transmit back to Earth for another 72 minutes before contact was lost with Cassini as it dipped below the horizon.
