On Friday at 7:55 a.m. ET, the world said goodbye to Cassini after 20 years in space and 13 years orbiting Saturn and its moons, providing incredibly detailed, high-resolution photos of what many consider the jewel of our solar system.
Our spacecraft has entered Saturn’s atmosphere, and we have received its final transmission.
Scientists and engineers altered the orbit of the spacecraft to run into Saturn, where it would safely burn up in its atmosphere.
“And it began changing the way we view the habitability or potential habitability of moons in the outer part of our solar system.”
Allowing Cassini to run out of fuel would leave NASA no way to control the spacecraft. One day it could crash into Enceladus or even Titan, Saturn’s largest moon, which is also being studied for potential habitability.
“Now because of the importance of Enceladus that Cassini has shown us, and of Titan, another potential world that could be habitable for life, perhaps not like we know it, but perhaps completely different than ours, we had to make decisions on how to dispose of the spacecraft,” Green said.
“And that led us, inevitably, to the plan of taking Cassini and plunging into Saturn.”
On the plus side, Cassini’s Grande Finale has given us unprecedented views of the planet’s north pole as well as its intricate ring system. For the first time in its mission, the spacecraft flew between the planet and the rings.
And, with its success and valuable insight into the potential habitability of other worlds, it’s likely there could be new missions.
“We might find in fact a higher probability than I’m willing to admit right now that life exists in the interior of Enceladus.”
While astronomers and planetary enthusiasts may miss the data and photos gathered by Saturn, NASA’s Juno spacecraft is also orbiting Jupiter. And there are plans for the Europa Clipper, which will conduct flybys of another icy, potentially habitable moon, Europa.
If there is a chance for life to be found in the Saturn system, NASA is eager to protect it.
