The detector is approaching the task of completing the last gap between Saturn and its aura. On September 15th, the prestigious “Space Veterans” will rush into the Saturn’s atmosphere, forever and it explores According to foreign media reports, NASA’s Cassini detectors are gradually close to the completion of its last pass through Saturn and its aura between the narrow gap Mission, September 15, the outstanding performance of the “space veterans” will be a burst into Saturn’s atmosphere, and it will always explore the planet into one. The Cassini spacecraft is currently running on a track called Scientist called “Magnificent Chapter”, and the Cassini spacecraft is flying around the track, which is closer to Saturn’s atmosphere, Eventually it will burn directly into the atmosphere of Saturn. The last lap of the Cassini spacecraft will begin on September 9th (Saturday), after which it will be ready to draw a successful journey for its long 20-year-long space Dot.

On the last lap of Saturday’s execution, the Cassini spacecraft had only about 1680 kilometers from the top of the Saturn’s cloud. About two days later, the Cassini spacecraft will fly the last time Saturn’s largest satellite, Titan, and the distance between the spacecraft and Titan is about 11.9 million kilometers. The flight over Titan will allow the spacecraft to Adjust the track, direct rushed to Saturn, which is Cassini spacecraft for their own set of death, it will not go back.

Just last week, NASA released the a new image, showing the spectacular picture of the clouds on Saturn can be seen over the Arctic in the star aura giant planets, the summer solstice midnight, rotating clouds Seems to “hang on the world”

September 14, Cassini spacecraft will seize the last batch of Saturn’s photos in his life, the Saturn’s Arctic over the hexagonal mysterious gas cloud and Titan And Titan for the last observation. After that, the Cassini spacecraft will aim the antenna at the end of the earth and begin to return the data and will always stick to the last moment of its burning into the Saturn’s atmosphere on September 15th.

The exploration of the Cassini spacecraft has brought us a number of groundbreaking discoveries, including the changes in Saturn’s season, the striking resemblance between Titan and the Earth’s environment, On the huge underground ocean and polar water ice fountain and so on. Curt Niebur, a Cassini project scientist, said in a conference call with media reporters last week: “The Cassini mission is an incredible, incredible, straightforward The perfect example of success. “

NASA said that on September 15, when the spacecraft finally rushed into Saturn’s atmosphere, it would send back almost real-time Saturn’s atmospheric detection data until the last moment of life -Is expected to September 15, US Eastern time 7:54 (Beijing time on September 15 19:54), Cassini detectors will eventually lose contact with the earth communication. The mission group said that the Cassini spacecraft in the last few laps to collect the Saturn aura particles data show that the inner stars of Saturn’s material particle quality lighter than the original.

就在上周,美国宇航局对外发布了一张最新图像,展示了土星上壮观的云层图景,可以看到在这颗光环巨行星的北极上空,夏至时分,旋转的云层似乎“悬浮于这世界之上”

This may indicate that the age of these particles is younger than expected, presumably about 120 million years, so there is no doubt that it was formed after the birth of the solar system for a long time.

When Cassini’s last lap traverses the area between Saturn and the halo, it also observes the Saturn’s atmosphere and measures some key data to help scientists more accurately calculate Saturn’s rock Kernel size.

This is one of Saturn’s many satellites, but in this picture, Titan seems to be the only companion of Saturn. When the picture was taken, the Cassini spacecraft were about 1.5 million kilometers from the small satellite. Since 2004, the Cassini spacecraft has been investigating a huge system of Saturn and 62 known satellites that follow it , The data sent during the mission to the scientists published more than 4000 scientific papers.

NASA decided to make it take the initiative to fall into Saturn, as the Cassini spacecraft is gradually depleted, so as not to cause a chance to live on Titan, Titan, or other potentially potentially livable environmental conditions The environment of the frozen satellite poses pollution.

By letting the Cassini spacecraft take the initiative, NASA will ensure that any microbes that have survived from Earth on the Cassini spacecraft and who have survived until now will be destroyed without causing any other planet Pollution.

Just last week, NASA released the a new image, which shows a picture of the spectacular clouds on Saturn, which is the day that Cassini captured on “the magnificent final chapter,” before action The

In this stunning latest image of the United States, you can see the sky in the aurora giant planets over the summer solstice, the rotating clouds seem to “hang on the world”, but soon after , It will fall into the darkness for many years.

Cassini spacecraft from the middle of August this year, the implementation of the last five laps in the first lap mission, so that they have never arrived before, from Saturn’s nearest location. On August 20, the image it sent back was simply scared of Heaven – this was the first time that a spacecraft had taken the image in the gap between the halo and Saturn and passed the image.

A few days before the opening of the “magnificent final chapter” mission, the Cassini spacecraft returned to a group of Titan photos. This is Saturn’s largest satellite, through the dense atmosphere, can vaguely see some of its details on the surface

April 26, 2017 is the Cassini spacecraft began to pass through Saturn and its halo gap between the first lap mission Day, in a picture taken on the same day, Cassini from about 270,000 km distance was observed at the time was still sunny Saturn Arctic over. May 24, 2017 is Saturn’s northern hemisphere summer solstice, this time Saturn Arctic light conditions the best day.

After that day, the northern hemisphere of Saturn midday height of the sun began to decline, and ultimately, Saturn will enter the long Arctic night, can reach a length of the entire planet. NASA said: “Cassini’s long mission time allows us to long-term observation of Saturn’s seasonal changes.” (Morning)
