Why did they crash Cassini into Saturn?
Having expended almost every bit of the rocket propellant it carried to Saturn, operators deliberately plunged Cassini into the planet to ensure Saturn’s moons remain pristine for future exploration—in particular, the ice-covered, ocean-bearing moon Enceladus, but also Titan, with its intriguing pre-biotic chemistry.
Why did they 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.
What surprises did Cassini Huygens discover about Saturn’s moons Titan and Enceladus?
Read more on Titan. Cassini scientists were astonished when they found a plume spraying water vapor, icy particles and simple organic materials into space from the south polar region of Enceladus. Scientists determined that the jets are the source of material for Saturn’s E-Ring.
What did Cassini Huygens discovered?
Cassini’s decade-long mission made it possible to watch changes in Saturn’s dynamic ring system. The spacecraft discovered propeller-like formations, witnessed the possible birth of a new moon and observed what may be one of the most active, chaotic rings in our solar system (Saturn’s F ring).
What did Cassini discover about Saturn’s atmosphere?
They found that temperatures peak near the auroras, indicating that auroral electric currents heat the upper atmosphere. And both density and temperature measurements together helped scientists figure out wind speeds.
When did the Cassini spacecraft crash?
September 15, 2017
On September 15, 2017, the 20-year Cassini mission ended in a “death dive” into Saturn’s upper atmosphere, collecting data until the spacecraft broke apart and became part of the planet it set out to explore.
What has Cassini discovered about Saturn?
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.
What did the Cassini mission discover about Saturn?
What was Cassini known for?
Astronomer Giovanni Cassini is associated with a number of scientific discoveries and projects, including the first observations of Saturn’s moons. For this reason, the Cassini spacecraft that launched in 1997 and plunged into the planet in 2017 was named after him..
What was the purpose of the Cassini mission?
A joint endeavor of NASA, ESA (the European Space Agency), and the Italian space agency (ASI), Cassini was a sophisticated robotic spacecraft sent to study Saturn and its complex system of rings and moons in unprecedented detail. Cassini carried a probe called Huygens to the Saturn system.
How did Cassini end its missions?
Cassini survived for a total of 91 seconds in Saturn’s dense atmosphere, before tipping over backward during its last eight seconds and finally losing radio contact with Earth. The mission was over, as the probe succumbed to the increasing heat and pressure.
What moons did the Cassini mission discover?
Cassini was the first dedicated spacecraft to look at Saturn and its system. It was named for Giovanni Cassini, a 17th-century astronomer who was the first to observe four of Saturn’s moons — Iapetus (1671), Rhea (1672), Tethys (1684) and Dione (1684).
