How does Cassini communicate with Earth?
The Radio Science Subsystem sent radio signals from Cassini to Earth using the spacecraft’s large radio dish called the high-gain antenna. En route, the radio signal interacted with Saturn’s moons, rings or Saturn’s atmosphere. The spacecraft’s high-gain antenna had to be pointed toward Earth in order to send its data.
How long does it take to communicate with Cassini?
How long does it take for Cassini’s data to get to Earth? It takes about 1 hour and 20 minutes for the radio signals to reach us. The power of the transmitter is 20 watts. When received at the DSN antennas, the signal power is 10 to the -16th (0.0000000000000001) watts.
How did Cassini get its name?
About Cassini-Huygens. Where does the name ‘Cassini-Huygens’ come from? The spacecraft is named after two famous scientists. The Saturn orbiter is named after Jean-Domenique Cassini, who discovered the Saturnian satellites Lapetus in 1671, Rhea in 1672, and both Tethys and Dione in 1684.
Why is Cassini famous?
Cassini is known for his work in the fields of astronomy and engineering. Cassini discovered four satellites of the planet Saturn and noted the division of the rings of Saturn; the Cassini Division was named after him.
Is Saturn pure gas?
Saturn’s surface Saturn is classified as a gas giant because it is almost completely made of gas. Its atmosphere bleeds into its “surface” with little distinction. If a spacecraft attempted to touch down on Saturn, it would never find solid ground.
What is the meaning of Cassini?
Cassini division noun. : the dark region between the two brightest rings of Saturn.
How do you spell Cassini?

What is a quire?
: a collection of 24 or sometimes 25 sheets of paper of the same size and quality : one twentieth of a ream. quire.
What happened to Cassini?
On Sept. 15, 2017, the spacecraft made its final approach to the giant planet Saturn. This time, Cassini dived into the planet’s atmosphere, sending science data for as long as its small thrusters could keep the spacecraft’s antenna pointed at Earth. Soon after, Cassini burned up and disintegrated like a meteor.
