A week after its dramatic ‘death dive’ into Saturn’s atmosphere, NASA has released Cassini’s final images, revealing stunning last looks at the ringed planet and its mysterious moons.
From a view of Enceladus setting behind Saturn, to the site where Cassini would make its impact, the new images show just what the spacecraft observed leading up to its demise.
Cassini circled the planet for 13 years, helping to transform our understanding of the gas giant – and, thanks to its observations, scientists now know two of its moons have potential to host simple life.

There, Cassini entered Saturn’s atmosphere just hours later, to embark on its mission-ending plunge.
The spacecraft also captured detailed images of Saturn’s rings, even revealing a look at the small moon Daphnis and the waves it causes in the Keeler Gap.

These are the features created by small moonlets in the rings, as they attempt to open gaps in the ring material, according to NASA.
The Cassini spacecraft may be gone, but the remarkable observations gathered over the craft’s 13-year mission will continue to reveal new insights on Saturn and the mysterious worlds orbiting it for some time to come.
Just days after the dramatic conclusion to the craft’s mission, NASA released a stunning Cassini observation of the planet’s ‘yin-and-yang moon,’ Iapetus.
The photo is one of Cassini’s last looks at the 914-mile-wide moon, revealing the striking dichotomy of its surface, long known to be bright on one side and dark on the other.
The strange moon is Saturn’s third-largest satellite.

This false-color ‘farewell’ view combines individual frames captured with filters sensitive to ultraviolet, green, and infrared light, according to NASA, and looks toward the Saturn-facing hemisphere of Iapetus.
For centuries, scientists have questioned Iapetus’ unusual ‘yin-yang’ appearance.
But, thanks to Cassini, they may have solved the mystery of its contrasted surface.
‘Cassini observations of Iapetus support the prevailing theory that led to the understanding that the dichotomy of the surface is due to a combination of infalling dust from outside of the moon followed by a migration of water ice from the darker (therefore warmer) areas to the cold, brighter surfaces,’ NASA explains.

Cassini captured this last look at Iapetus on May 30, from roughly 1.5 million miles away.
NASA’s Cassini mission came to a ‘bittersweet’ conclusion early Friday morning, as the historic spacecraft plunged into Saturn’s atmosphere to become one with the gas giant planet it had studied for 13 years.
As mission scientists said their farewells to the craft and prepare to examine its final observations, footage emerged of the dramatic moment Cassini first lifted off 20 years ago, to embark on its ‘billion mile trek to Saturn.’
The breathtaking footage takes us back to the Cape Canaveral launchpad on October 15, 1997, as mission control counts down to the start of a journey that brought an ‘incredible wealth of discoveries.’

Cassini launched in 1997 from Cape Canaveral Air Force Station in Florida, bringing it past Venus (twice), Earth, and Jupiter on its way to Saturn.
But, it would be many years – and a billion miles – before it reached its target.
‘We have cleared the tower, and the Cassini spacecraft is on its way to Saturn,’ mission control can be heard saying in the 20-year-old footage, as the rocket breaks through the clouds.
The spacecraft arrived to Saturn in 2004, marking the start of its historic 13-year mission studying the planet and its moons.
‘This is the final chapter of an amazing mission, but it’s also a new beginning,’ Thomas Zurbuchen, associate administrator for NASA’s Science Mission Directorate at NASA Headquarters in Washington, said as the space agency marked the end of Cassini’s mission.
‘Cassini’s discovery of ocean worlds at Titan and Enceladus changed everything, shaking our views to the core about surprising places to search for potential life beyond Earth.’
After 20 years in space, Cassini spacecraft finally completed its suicide mission at 7:56 a.m. (ET) Friday, plunging into Saturn’s atmosphere.

‘The Cassini operations team did an absolutely stellar job guiding the spacecraft to its noble end,’ said Earl Maize, Cassini project manager at JPL.
‘From designing the trajectory seven years ago, to navigating through the 22 nail-biting plunges between Saturn and its rings, this is a crack shot group of scientists and engineers that scripted a fitting end to a great mission.
‘What a way to go. Truly a blaze of glory.’
The confirmation of the mission was received at Nasa’s Jet Propulsion unit at 07:56 EST (12:56 BST).
Upon receiving the news, Earl Maize, program manager for Cassini, announced: ‘The signal from the spacecraft has gone. Congratulations, this has been an incredible mission and incredible spacecraft.’

In its thirteen years at Saturn and two decades in space, the $4 billion (£3 billion) Cassini probe has transformed our understanding of the ringed planet and its moons.
It has watched giant storms on the gas giant, recorded its ring system in stunning detail, and revealed incredible new insights on the potential habitability of Saturn’s moons.
The decision to kill off Cassini was taken because the craft would soon run out of fuel and become impossible to steer. Scientists feared a collision with Titan or Enceladus – two of Saturn’s moons that in the past 10 years have shown a potential to host simple life.

Then its large external structures, including the 11ft wide dish antenna and 30ft long magnetometer boom will have weakened and broken apart, followed by other body-mounted components, and eventually the leading face of the space craft itself.
It is also possible that propellant left in Cassini’s fuel tanks may have exploded.
Meanwhile, atmospheric friction will have sent temperatures soaring.
By the time what was left of Cassini reached the cloud tops it would have been transformed into a glowing fragmenting meteor, hotter than the surface of the sun.

Finally, intense heat and pressure would have caused every part of the space craft to melt and dissociate, scattering its atoms to the winds of Saturn.
Cassini’s death plunge was the climax of a ‘grand finale’ that saw the probe slip between Saturn and its rings in 22 daring orbits.
Fifteen minutes before the end, the voice of Dr Maize could be heard in a live stream from mission control telling his team: ‘This might be a good time to pass out the farewell peanuts.’
Earlier Jet Propulsion Laboratory director Mike Watkins told a Nasa interviewer: ‘It’s kind of a bitter-sweet event for all of us.
‘For me personally, it’s more sweet than bitter, because Cassini has been such a fantastic mission.
During the live feed, experts from Nasa described the event as ‘the last hour of the last chapter of Cassini’s Grand Finale.’
