Cassini spacecraft has completed all services

Cassini has completed the grand final to plunge to death in the atmosphere of Saturn. The extraordinary spacecraft has gone after 20 years of adventure and 13 years orbiting Saturn. Cassini spent the last 90 seconds working hard to deliver Saturn's secrets to mankind on Earth.

The Cassini spacecraft entered the atmosphere of Saturn around 3:31 a.m. PDT on September 15th and immediately start running all the stabilizer procedures to try to keep themselves upright. The signal arrives on Earth at 4:54 a.m because the spacecraft lost its efforts in the atmosphere of Saturn.

"The signal from the spacecraft is missing, it's an incredible mission, incredible spacecraft, and you're all a great team," said Cassini project manager Earl Maize at the mission control center at NASA's Jet Propulsion Lab.

Since its launch in 1997, the probe covered a total of 7.9 billion kilometers, uploading over 635 gigabytes of science data, and taking over 450,000 images. Completed 294 Saturn orbits, found 6 months, made 162 nearest flybys.

The team of scientists decided to sacrifice the spacecraft when it ran out of fuel, rather than risking a collision with one of the potentially habitable moons and contaminating with the earth's microbes that might be attached.

"The protection of the planet and our desire to return to Enceladus, to the Titan, to the Saturn system, we must protect them for future exploration," said NASA's planetary science division director Jim Green.

On September 13th and 14th, Cassini performed the last lap in the largest Saturn system, taking a picture of the mosaic of Saturn's color and ring, the Enceladus circuit behind Saturn, Titan and a small moon on a particle ice ring.



In the early hours of September 15, the spacecraft configures itself to switch from a tape recorder to a transmission. At that point, the last and only job is to send everything directly to Earth in real time.

The ion-mass spectrometer faces directly to Saturn to sense the atmosphere for the first time and investigates a phenomenon called "heavy rain" where water and ice from the rattling rings into the atmosphere. This idea was introduced in the early 1980s, but Cassini has shown that this is more complicated than theory.

Around 3.31 am entering the atmosphere about 10 degrees north of the equator, crashing about 34 kilometers per second. Cassini instantly measured the temperature, magnetic field, plasma density and Saturn's topsoil composition for the first time.

When touching the atmosphere, Cassini begins to keep the antenna fixed to Earth despite the atmospheric forces that are trying to tilt on the side. The spacecraft is trying to stabilize itself, but in vain. Fell faster and faster.



Atmospheric friction destroys the spacecraft, bit by bit. The thermal blanket burns, then the aluminum component begins to melt. The spacecraft may fall another 1,000 kilometers as it crumbles like a meteor.

No future missions are planned to Saturn, although some Cassini alumni have been working on the proposal. Scientists are now putting sights on Jupiter and the cold and possibly environmentally-friendly moons for humanity.

ESA's Jupiter Icy Moons Explorer (JUICE) and NASA's Europa Clipper hope to launch around 2022. The mission will pave the way for landing on the moon Europa that can directly search for life at sea beneath the surface.
