How NASA's $3.3 billion Cassini spacecraft will die on Friday

Saturn probe heads towards destruction

On Friday, Cassini will make a forced descent into Saturn where it will officially end its 13-year mission orbiting the planet to study its moons. However, eight of Cassini's 12 science experiments will continue to run until the last second, gathering never before seen data about Saturn's atmosphere.

Ian Griffin says Cassini has had an fantastic mission which has transformed our understanding of Saturn.

For its swan song, the spacecraft will gather data on Saturn's clouds as it hurtles towards them at 112,000 km/h. We have new books coming out about Saturn, the rings, the magnetosphere, so many new things Cassini has discovered. When they can no longer hold the spacecraft steady, it will start to tumble, communication will be lost, and the probe will burn to a cinder.

Its mission extended twice, Cassini's findings transformed scientists' understanding of Saturn, its rings and its moons. "It'll be a mixture of sadness and pride and joy at having worked on the mission and saying goodbye to my Cassini family".

Equifax hack: What to do if your identity was stolen
A fraud alert allows creditors to get a copy of your credit report as long as they take steps to verify your identity. Equifax was in a unique position because it did not have an agreement with the people whose information it carried.

In the near term, though, numerous same researchers will be working on America's Clipper mission to Europa, a moon of Jupiter that in many ways is just a big version of Enceladus.

He told Rachel Smalley Cassini has sent back wonderful images of Saturn's rings and discovered water on one of it's moons. The spacecraft found that the region between Saturn and its rings are dust-free, a surprising discovery because the rings itself are primarily made up of dust particles. There are so many puzzles at Saturn.

The Canberra Deep Space Complex is assisting with the mission. If it's possible that moons like Titan and Enceladus might now, or could one day, harbor life, then humanity has a responsibility to leave such landscapes uncontaminated. Hydrocarbon rivers carve canyons on the ground and feed three hydrocarbon seas and hundreds of lakes. No spacecraft has ever been so close to Saturn.

During multiple close flybys, Cassini used its full science payload to detect and analyze water-rich plumes erupting from the moon's south pole far into space, a spectacular discovery that McEwen considers one of the highlights of the entire mission. Hydrothermal vents are thought to warm the hidden ocean's floor. Cassini also carried the Huygens probe, which landed on Titan, Saturn's largest moon, in 2005 and sent data about the moon's surface and atmosphere to Cassini for 72 minutes before the signal was interrupted by the horizon.

Goals from Ganso, Wissam Ben Yedder and Nolito saw Sevilla claim a 3-0 win over Eibar at the Estadio Ramón Sánchez Pizjuan.

It will be possible, but hard, to observe Cassini's death from Earth, due to the spacecraft's small size and the position of Saturn in the sky. Any tiny fragments that survive the inferno will sink, melt, and ultimately become diluted in the planet's interior.

Regardless of whether they expected it, the two have worked together, and published scientific research papers together.

In 2011, Cassini photographed a massive storm that erupted on Saturn, which lasted for several months.

But Cassini hasn't answered all of scientists' questions. "There is no substitute for a flagship mission", Lunine says. "I have seen a lot of visual artists take images from Saturn, primarily the rings, and use those as motifs, backgrounds or design elements in their art".

Tropical Storm Katia Weakens As It Enters Mexico
Katia is expected to produce total rain accumulations of 10 to 15 inches over northern Veracruz , eastern Hidalgo , and Puebla . Isolated maximum amounts of 25 inches are possible in northern Veracruz , eastern Hidalgo , Puebla and San Luis Potosi .

Spilker is part of a NASA team that proposes to go back to Enceladus to look for signs of life. "Does the ocean of Enceladus have evidence of life?"
