Cassini’s noble self-sacrifice: protects two or living satellites

Cassini detectors found large amounts of water vapor, organic compounds and other substances in the “tiger” cracks near Titan Antarctica. The results of the survey after the detector show that the water may come from the Titanic cold under the shell of the liquid ocean. According to foreign media reports, the current NASA “Cassini” detector will soon be staged a suicide-style space collision, which is a noble self-sacrifice, the collision process (Figure), according to foreign media reports, Protects two Saturn satellites that may support the existence of life.

The Cassini Detector is about to run out of fuel, so its historical mission is nearing completion. But on the morning of September 15th, the Cassini Detector control officer began to control the detector towards the top of the Saturnic clouds, primarily to protect the two most astronomers concerned Saturn satellites – Titan and Titan.

In this case, “protection” means keeping the original state, the Cassini Detector’s controller wants to avoid a situation – runaway drift through Saturn’s satellite system, Satellite surface.

Cassini detectors have been in space for 20 years, but the Earth’s microbes are still very tenacious and are likely to sojourn on the detectors. If any kind of microorganism on Earth can reach Titan and Titan, they are likely to survive there, and before the Cassini Detector observes that the two satellites are potentially livable. The diameter of the Titan is 5150 km, is the second largest satellite in the solar system, from the perspective of space, it looks like a blurred view of


Orange planet, it is because it has a thick layer of nitrogen-based atmosphere wrapped around the satellite surface. However, the Cassini Detector reveals a number of noteworthy phenomena through radar detectors: Titan and Ethane, as well as rivers that carry hydrocarbon rainwater into lakes and oceans.

Titan is the only one surface of the planet Earth in addition to a stable liquid, Cassini also found that large amounts of organic substances Titan, the presence of structure in the atmosphere Titan An important element of life. Therefore, some celestial biologists believe that Titan may have a large number of life forms, if they really exist, then the satellite depends on the life of liquid life will be completely different from the Earth’s life.

Talking about liquid water, Titan has potentially found a lot of great discoveries that the satellite’s cold surface may potentially be a global ocean, so it is conceivable that Titan may have two different lives Form – one that lives on the surface of the planet depends on the survival of liquid hydrocarbons; the other is the need for groundwater to sustain life.

Researchers hope to learn more about Titan for a longer period of time. At present, different research teams have begun to study Titan, one of which has designed the “Titan tracker” Is a UAV, can be from the Titan land and air for survey and analysis; In addition, a mechanical submarine will be on the Titan underground sea exploration.

The Cassini Detector also carries a European Space Agency Detector called “Huygens”, which landed on Titan in January 2005, the first human space probe soft landing On the solar satellite. So far, Huygens detectors are the only detectors in human history that have taken close-up images on Titan’s surface.

You may wonder why the Cassini Study Group is committed to protecting Titan, since the Huygens probe has landed the planet before. Cassini detectors show that the 127 satellites were more suitable for living than scientists had expected, so scientists should still be able to protect the satellites as much as possible.


The bright Titan has a diameter of only 504 km, about one tenth of the Titan diameter, but this is a very Mysterious planet In 2005, Cassini detectors found large amounts of water vapor, organic compounds and other substances in the “tiger” cracks near Titan Antarctica. The results of the survey after the probe show that the water may come from the liquid ocean under the Titanic cold shell, and this ocean is likely to provide heat for the life of the hydrothermal “hot area” for the survival of the potential form of life provide energy. Curt Niebur, a scientist at Cassini, argues that Titan is very small and so far away from the sun that it does not seem to take advantage of any of its underground oceans’ business activities. Frozen for a long time. But the strong gravitational pull from Saturn, as well as the heat generated by the internal friction of Titan, is sufficient to keep the ocean liquid shaking.

Two jet plume, then looking for complex organic molecules, some of which organic molecules can in theory give birth to life. (Allure)
