After 20 years in space, Nasa's famed Cassini spacecraft made its final death plunge into Saturn on Friday, ending a storied mission that scientists say taught us nearly everything we know about Saturn today and transformed the way we think about life elsewhere in the solar system.
Cassini, an international project that cost US$3.9 billion and included scientists from 27 nations, disintegrated as it dove into Saturn's atmosphere at a speed of 75,000 miles per hour.
"The signal from the spacecraft is gone," said Cassini program manager Earl Maize of NASA's Jet Propulsion Laboratory.
"I hope you are all as deeply proud of this amazing accomplishment," he told colleagues at mission control. "This has been an incredible mission, an incredible spacecraft and you are all an incredible team."
Cassini's final contact with Earth came at 7:55 am EDT. Its descent into Saturn's atmosphere began about an hour and a half earlier, but the signal took that long to reach earth because of the vast distance.
Cassini's plunge into the ringed gas giant -- the furthest planet visible from Earth with the naked eye - came after the spacecraft ran out of rocket fuel after a journey of some 4.9 billion miles.
Its well-planned demise was a way to prevent any damage to Saturn's ocean-bearing moons Titan and Enceladus, which scientists want to keep pristine for future exploration because they may contain some form of life.
"There are international treaties that require that we can't just leave a derelict spacecraft in orbit around a planet like Saturn, which has prebiotic moons," said Maize.
Three other spacecraft have flown by Saturn - Pioneer 11 in 1979, followed by Voyager 1 and 2 in the 1980s.
But none have studied Saturn in such detail as Cassini, named after the French-Italian astronomer Giovanni Domenico Cassini, who discovered in the 17th century that Saturn had several moons and a gap between its rings.

"This is the final chapter of an amazing mission, but it's also a new beginning," said Thomas Zurbuchen, associate administrator for NASA's Science Mission Directorate.
"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."
Cassini launched from Cape Canaveral, Florida in 1997, then spent seven years in transit followed by 13 years orbiting Saturn.
In that time, it discovered six more moons around Saturn, three-dimensional structures towering above Saturn's rings, and a giant storm that raged across the planet for nearly a year.
The 22 by 13 foot spacecraft is also credited with discovering icy geysers erupting from Enceladus, and eerie hydrocarbon lakes made of ethane and methane on Saturn's largest moon, Titan.
In 2005, the Cassini orbiter released a lander called Huygens on Titan, marking the first and only such landing in the outer solar system, on a celestial body beyond the asteroid belt.
Huygens was a joint project of the European Space Agency, Italian Space Agency and NASA.
"The mission has changed the way we think of where life may have developed beyond our Earth," said Andrew Coates, head of the Planetary Science Group at Mullard Space Science Laboratory at University College London.
"As well as Mars, outer planet moons like Enceladus, Europa and even Titan are now top contenders for life elsewhere," he added.
"We've completely rewritten the textbooks about Saturn."
Linda Spilker, Cassini project scientist, likened Cassini's mission to a marathon.
"For 13 years we have been running a marathon of scientific discovery, and we are on the last lap," she said early Friday.
Eight of the spacecraft 12 scientific instruments were on, capturing data, in Cassini's last moments, before it disintegrates like a meteor, she said.
"We are flying more deeply into Saturn than we have ever flown before," she said.
"Who knows how many PhD theses might be in just those final seconds of data?"
Already, some 4,000 scientific papers have been based on data from the mission, said Mathew Owens, professor of space physics at the University of Reading.
"No doubt scientists will be analyzing the information from its final, one-way trip into Saturn's atmosphere for years to come," Mr Owens said.

THREE POSSIBLE REPLACEMENTS
Khalfan Mubarak
The Al Jazira playmaker has for some time been tipped for stardom within UAE football, with Quique Sanchez Flores, his former manager at Al Ahli, once labelling him a “genius”. He was only 17. Now 23, Mubarak has developed into a crafty supplier of chances, evidenced by his seven assists in six league matches this season. Still to display his class at international level, though.
Rayan Yaslam
The Al Ain attacking midfielder has become a regular starter for his club in the past 15 months. Yaslam, 23, is a tidy and intelligent player, technically proficient with an eye for opening up defences. Developed while alongside Abdulrahman in the Al Ain first-team and has progressed well since manager Zoran Mamic’s arrival. However, made his UAE debut only last December.
Ismail Matar
The Al Wahda forward is revered by teammates and a key contributor to the squad. At 35, his best days are behind him, but Matar is incredibly experienced and an example to his colleagues. His ability to cope with tournament football is a concern, though, despite Matar beginning the season well. Not a like-for-like replacement, although the system could be adjusted to suit.

Moral education needed in a 'rapidly changing world'
Moral education lessons for young people is needed in a rapidly changing world, the head of the programme said.
Alanood Al Kaabi, head of programmes at the Education Affairs Office of the Crown Price Court - Abu Dhabi, said: "The Crown Price Court is fully behind this initiative and have already seen the curriculum succeed in empowering young people and providing them with the necessary tools to succeed in building the future of the nation at all levels.
"Moral education touches on every aspect and subject that children engage in.
"It is not just limited to science or maths but it is involved in all subjects and it is helping children to adapt to integral moral practises.
"The moral education programme has been designed to develop children holistically in a world being rapidly transformed by technology and globalisation."
$1,000 award for 1,000 days on madrasa portal
Daily cash awards of $1,000 dollars will sweeten the Madrasa e-learning project by tempting more pupils to an education portal to deepen their understanding of math and sciences.
School children are required to watch an educational video each day and answer a question related to it. They then enter into a raffle draw for the $1,000 prize.
“We are targeting everyone who wants to learn. This will be $1,000 for 1,000 days so there will be a winner every day for 1,000 days,” said Sara Al Nuaimi, project manager of the Madrasa e-learning platform that was launched on Tuesday by the Vice President and Ruler of Dubai, to reach Arab pupils from kindergarten to grade 12 with educational videos.
“The objective of the Madrasa is to become the number one reference for all Arab students in the world. The 5,000 videos we have online is just the beginning, we have big ambitions. Today in the Arab world there are 50 million students. We want to reach everyone who is willing to learn.”
