Return to Saturn NASA plans new space mission plan

The figure is the Cassini detectors observed in Saturn and Saturn ring structures. September 15, NASA Cassini detectors burned in Saturn’s atmosphere, ending a 13-year history of Saturn’s exploration, according to foreign media reports, September 15, NASA Cassini detectors in Saturn’s atmosphere, The survey images and data provided by the device completely changed the scientists’ understanding of the solar system and were more aware of the planet’s condition of potential living conditions.

For example: Cassini detectors found Titan in the Titan Sea, found on the surface of the Titan sprinkler water geyser, the two satellites are worthy of further study and analysis, like around with a ring Saturn and the entire Saturn system. “Although the Cassini Detector has completed its historic mission and left us, we still need to do so,” said Earl Maize, director of the Java Aerospace Propulsion Laboratory and Cassini Project. To explore Saturn, we know that we have to explore Saturn and its mysterious satellites! “

In fact, many research teams are planning how to” return to Saturn, “NASA’s next generation” new front Frontiers “project operates five exploration programs, including” New Front “Pluto Detector, Juno Jupiter Orbiter and OSIRIS-Rex Asteroid Sampling Detector. Cassini Detector was the first Saturn Atmospheric Detector, and a “new frontline” project will continue to explore Saturn, and even the “new frontline” project will continue to explore Saturn. Will go beyond the Cassini detectors, to further expand the scope of exploration.

“Saturn Explore Internal and Atmospheric Detector (SPRITE)” will enter the Saturn-intensive atmosphere, survey and analysis of Saturn’s atmospheric composition and structure of about 90 minutes before the final decomposition and combustion. By contrast, the Cassini Detector did not do this, and it lasted only 1-2 minutes in Saturn’s atmosphere. Amy Simon, head of NASA’s Goddard Space Flight Center project, points out that the basic measurements of Saturn’s internal structure and rare gas abundance can better analyze the formation of the solar system, while , Help us to better understand the extrasolar planets.

Saturn explores internal and atmospheric detectors that will be responsible for carrying out such surveying tasks, and its survey data will help to acquire a large number of Saturn “real data”. Cassini detectors 127 times overflew the Titan surface, the detector was equipped with the European Space Agency’s “Hui more Sri Lanka Detector “, which landed on the surface of Titan in January 2005, it became the first probe in the outer solar system soft landing planet. The observations of the Cassini and Huygens detectors will reveal the mystery of the Saturn system, and the observations show that the Titan sky has hydrocarbon rain, the surface of the methane lake and the ocean, and some oceanic areas Even close to the Earth’s Black Sea area. We know that the carbonaceous material that constitutes life – complex organic chemicals floating in the Saturn-intensive nitrogen-containing atmosphere, and eventually landed on Titan’s surface.

Celestial biologists say it is likely that these exotic extraterrestrial landscapes have the conditions to nurture life. Cassini detectors have shown that Titan may also be potentially another livable environment: the liquid ocean under the crust. In fact, the Cassini probe in the process of collision with Saturn, as far as possible to avoid the collision of Titan and Titan, so as to avoid the two planet suffered earth pollution of the micro-organisms.

At present, the new frontline project proposes a space program called “Oceanus”, which aims to survey and analyze Titan’s surface and underground marine environment, launching detectors to Titan Hovering over. For example, the detector can observe the organic matter in the Titan atmosphere and help to determine the thickness and hardness of the Titan’s crust and whether to transfer internal heat to the surface.

The “Ohio” space program will continue to analyze the surprising discovery of the Cassini detectors by analyzing the exchange of organic matter between meteorological cycles, analyzing the exchange process between the atmosphere, surface and sub-surface, Titan’s life livability.

At the same time, the new frontline project also designed the “Titan Dragonfly Detector”, which will launch a UAV from the air and ground to study the satellite. Earlier this year, Elizabeth Turtle, a missionary scientist at the Johns Hopkins University Applied Research Laboratory planet, said that flying on Titan was easier than Earth, Because the Titan atmosphere is thicker than the earth, and the Titan gravitation is only 14% of the Earth’s gravity. This means that the detector can travel several kilometers at a time. The Dragonfly UAV can study the detailed situation of organic matter in different areas of Titan. “The Dragonfly UAV is an innovative concept that can explore the different areas of Titanic, depicting the livable character of the Titan environment, investigating the chemical processes before the origin of life, searching for water,” says Elizabeth, Base or hydrocarbon chemical life. “She and her colleagues published the report at the 48th Lunar and Planetary Science Conference. <12The other two space missions focused on the Titan II, before the Cassini Detector observes the discovery of the Titanic Surface (2).

There is a jet plume. “We are very surprised that we will observe the suitability of Titan,” said Jim Green, director of planetary science at NASA. , Or the potential life of the outer satellite system.

This is because the water in the geosystems’ s geyser is evident from the liquid ocean of water, and the liquid water is shaking under the icy crust of Titan. Cassini observations suggest that the chemical energy source of this underground ocean can support the survival of life. But the researchers hope to learn more about Titan’s underground oceans and geysers, a new plan for the space project called “Titan Life Explorer (ELF)”, which will quickly and repeatedly through the plume, Collect and analyze plume molecules. The Titan life explorer will search for complex organic molecules, which may become a sign of the origin of life before confirming the existence of the form of life. “Jonathan Lunine, head of Cornell University in the United States, says it is a free sample, and we do not need to log on to satellite surfaces, drill holes, melt surface substances and other complex operations. Cassini detectors have collected some samples of the Titan plume, and we will now perform a more accurate mass spectrometer.

It is reported that in the 12 new front-line project candidates, the other seven were surveyed Venus, comet or the moon. Green pointed out that the Cassini era has ended, the future we will return to the Saturn orbit, the Saturn and mysterious satellite survey analysis. NASA “Voyager” detectors visited Saturn twice in 1980-1981, about 30 years Cassini detectors to explore Saturn, we believe that the next Saturn survey mission will start faster! (Allure)
