How did the Cassini mission end?
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.
What was Cassini's last message?
"The spacecraft's final signal will be like an echo. It will radiate across the solar system for nearly an hour and a half after Cassini itself has gone," said Earl Maize, Cassini project manager at NASA's Jet Propulsion Laboratory, in a statement.Sep 14, 2017
Where is Cassini Huygens now?
This animation shows the journey, key events and current position of the NASA/ESA/ASI Cassini spacecraft. The ESA Huygens probe is now on Titan.
How is Titan not like the Earth?
Because Titan is less massive than Earth, its gravity doesn't hold onto its gaseous envelope as tightly, so the atmosphere extends to an altitude 10 times higher than Earth's—nearly 370 miles (600 kilometers) into space.Feb 4, 2021

What is NASA's Cassini mission?
Cassini was, in a sense, a time machine. It revealed the processes that likely shaped the development of our solar system. 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.Jun 9, 2021
What happened to the Galileo probe?

Where is Voyager 1 now?
NASA's Voyager 1 spacecraft is currently over 14.1 billion miles from Earth. It's moving at a speed of approximately 38,000 miles per hour and not long ago passed through our solar system's boundary with interstellar space.May 11, 2021
What would happen if you landed on Saturn?
The outer part of Saturn is made of gas and the very top layers have about the same pressure as the air does on Earth. So, if you tried to walk on this part of Saturn, you would sink through its atmosphere. Saturn's atmosphere is very thick and its pressure increases the deeper you go.19 hours ago
What happened Huygens probe?

Which of the Jovian giants was discovered mathematically?
Namesake. The ice giant Neptune was the first planet located through mathematical calculations. Using predictions made by Urbain Le Verrier, Johann Galle discovered the planet in 1846.
Is Juno still orbiting Jupiter?
Proposed in 2003 and launched in 2011, Juno arrived at Jupiter on July 4, 2016. The prime mission will be completed in July 2021. ... NASA has extended the mission of its Juno spacecraft exploring Jupiter. The extended mission involves 42 additional orbits.Jan 13, 2021
