SAN FRANCISCO, Sept. 15 evening news, after confirmation, today 19:55 hours, has been working for 20 years in space, “Cassini” spacecraft had crashed in Saturn’s atmosphere. The crash was about 10 degrees north of Saturn and about 120,000 kilometers per hour from the Saturn’s atmosphere. From the beginning of the contact with Saturn’s high-rise atmosphere, in less than a minute, the Cassini spacecraft was at high temperatures Friction under the fire and quickly disintegrate, into the Saturn in the sky across a meteor.
This is a planned suicide action. The Cassini spacecraft faithfully executed the command of the ground controller. Cassini spacecraft had almost exhausted the fuel, scientists do not want it to fall out of control and hit Titan and Titan may have a potential livable environment of the planet.
The position and time of the disappearance of the Cassini spacecraft signal are in advance. In the confirmation signal disappeared radio call, the Cassini detector project manager to cover sadness, tone pain. Scientists embrace each other, comfort each other, the screen can see someone crying and crying. But the director of the control center Earl Maize urges everyone to “congratulate everyone.” It is an incredible task, this is an incredible spacecraft, you are an incredible team.
The disappearance of the signal means that the Cassini spacecraft has disappeared in Saturn’s atmosphere. It can not survive more than 45 seconds when it comes into Saturn’s atmosphere. Tonight marks the end of a great age.
Cassini changed our understanding of Saturn for 13 years working around Saturn’s orbit. It has observed a huge storm system on Saturn, observing the fine structure of the particles in Saturn’s aura, and greatly deepened our understanding of the potential livable environment for Saturn’s frozen satellites.
Among them, Titan and Titan are particularly concerned about the two small satellites. On Titan, liquid methane raindrops fell from the sky, and there were rivers on the ground with lakes and oceans. Cassini spacecraft also equipped with a Huygens lander, which in 2005 successfully landed on the surface of Titan. In the picture of its return, you can see the smooth ground pebbles on the ground, which is the result of repeated erosion of the flowing methane sea.
And in Titan, Cassini also achieved good results.
Cassini observed the small particles in the surface of the small particles of ice particles and water vapor, and in 2008 arranged a walk from this “space fountain” in the feat.
When the Cassini spacecraft passes through the water column, it analyzes the sample of water vapor, and the results allow the scientists to conclude that there is a huge underground oceans in the underground area of Azerbaijan, There is a very likely condition for survival. After the Cassini spacecraft fell, the scientists have begun to discuss when to return to Saturn, with a more powerful, more advanced spacecraft to go there to study.
Cassini spacecraft era is over, but to explore eternity. (Morning wind)
