There is a satellite in the solar system. It is an ice world. There may be an ocean under the ice.The solar system is home to the earth. In our eyes the solar system is very large. The current technology of mankind can not get out of the solar system but the solar system is just like dust in front of the Milky Way. There are hundreds of billions of galaxies such as the solar system. Although the solar system is only a small Galaxy it has become extraordinary because of the existence of the earth.Earth is a living planet the ruler of this planet. The earth is able to give birth to life and human beings can not leave the boiling water. If there is no liquid water there will be no birth of life on Earth. And 71 % of our surface area is ocean. In human cognition water is the source of life and the probability of the birth of life on the planet of liquid water will be very large.Therefore after humans came out of the earth they began to search for extraterrestrial life. The first thing to see is whether the planet has liquid water. Scientists have discovered through astronomical telescopes that many terrestrial planets outside the solar system have the presence of liquid water so the probability of life on these planets will be much greater. However these terrestrial planets are relatively far from the earth. With the current scientific and technological solar system of mankind it is not yet possible to go out let alone explore planets outside the solar system.Due to the limitations of human science and technology we can only temporarily place the search for extraterrestrial life in the solar system. So the eight planets in the solar system which planet other than the Earth has liquid water? In fact so far no large amount of liquid water has been found on the surface of any planet. Previously scientists suspected that there may be liquid water on Mars but later regular exploration found that the surface of Mars was full of sand and no liquid water was found. However some time ago a detector discovered a huge ice puddle on Mars but this is only a long-term perspective. Whether or not it is really a large puddle still needs to be approached by future detectors to understand.For liquid water to exist on the surface of the planets of the solar system it must be within the habitable zone but there is no liquid water on the surface of Venus and Mars in the habitable zone. Planets outside the habitable zone are relatively low in temperature due to their distance from the sun and are less likely to have liquid water. Although the solar system has no liquid water on the surface of other planets except the Earth it does not represent the lack of water in the solar system.In fact the solar system does not lack water but many of them exist in the form of frozen water. We all know that Jupiter is the largest gaseous planet in the solar system. Its size and mass are very large so its gravity is also very strong which attracts many asteroids around it so Jupiter has a large number of satellites. Among them Europa has attracted the attention of scientists. Why is this?In December 1995 NASA's Galileo probe entered the orbit of Jupiter. In the first batch of observations the Galileo detector discovered that Europa was a cold world. After adjusting its orbit it passed about 351 kilometers above Europa and discovered ice that covered the mountains and covered a large amount of ice. Europa.Europa is an ice world. When Europa entered the list of scientists 'concerns he conducted a series of observations and studies on it resulting in more exciting discoveries. Originally scientists observed that Europa's geomagnetic North Pole was constantly changing moving about once every 5.5 hours. Maybe a lot of people don't understand. What does that mean?The change of the magnetic poles on the planet is a very important data. We know that the earth's geomagnetic North Pole moves at a rate of 20.5 meters per day. Its significance is to tell us that there is a liquid conduction layer under the ice of Europa. That is there is a huge liquid ocean under the ice. This discovery is very impressive. If Europa is just a planet full of ice there is nothing worth studying but if there is a liquid ocean under the Europa ice then the meaning is different.The existence of a liquid ocean means that there may be life. This is what makes scientists most excited. Perhaps mankind has been searching for extraterrestrial civilization for decades and may find it on Europa in the future. This is a big discovery that can carry people into history. Later American scientists used the Hubble Space Telescope to discover the pinnate jet of Europa and found a large amount of hydrogen and oxygen in the southern hemisphere of Europa. This is the electrolysis of water ice materials ejected from the surface cracks by the ocean under Europa ice. product.At this point the fact that there is a liquid ocean under the ice above Europa is no doubt but it is not easy to explore the ocean under this ice. The thickness of Enceladus ice may range from several kilometers to dozens of kilometers and the depth of the ocean below may reach tens to hundreds of kilometers. No less than the oceans of the earth. Don't underestimate the small size of the planet but the amount of water stored on it far exceeds the amount of water on the surface of the Earth. To understand whether there is life in the ocean under the Enceladus ice it is necessary to drill through the ice to go deep into the sea water. Therefore scientists designed a glacial drilling robot to serve the ice of Drilling Earth II. It looks like a torpedo. Nuclear propulsion can penetrate glaciers at least 30 kilometers thick.Although this glacial drilling robot is not difficult to manufacture it is also a difficult challenge to transport it to Europa and drill tools on Europa. Although it has strong nuclear power propulsion scientists estimate that it will take two or three years to drill through the ice above Europa.However at present this is only an idea. With current human technology we have not yet been able to go to Europa for ice drilling missions. What we can do now is to follow the surface of Europa and see if we can have further. Discovery. Scientists have suggested that we can send a spacecraft to the equatorial region of Europa. There are many huge icicles in that place. These icicles are formed by the solidification of liquid water emitted by the ocean under the ice.If there is life in the ocean under Europa's ice there may also be primitive life like microorganisms bacteria in these erupted liquid waters. Just like the water on our earth under a microscope we find some bacteria and other tiny life. If the existence of life can be found in the icicles formed by these erupted liquid water it can be determined that there is life in the ocean under the ice and there may be complex organisms such as fish.
Official operation of two Fengyun meteorological satellitesThe official operation of Fengyun No. 3 D Star and Fengyun No. 2 H Star and its ground application system on January 1 will further enhance the comprehensive capabilities of China's meteorological satellites and effectively support 'global forecasting global forecasting and global services' the China Meteorological News intern reporter Yeshanshan reported. It also plays an important role in serving the Belt and Road Initiative.The Fengyun II H star was launched on June 5 2018 and is the closing of China's first-generation geosynchronous orbit meteorological satellites. Since January 1 this year Fengyun II H has conducted 28 full-disc scanning observations and 20 northern hemisphere observations every day. In addition high-frequency subregional encrypted observations can be launched according to the needs of countries along the Belt and Road. It provides strong support for meteorological services and disaster prevention and reduction. After the operation of the business the satellite formally formed a business model of 'multi-star in-orbit coordinated operation mutual backup and timely encryption' with the Fengyun II E star F star and G star.Fengyun III D Star is the fourth star of China's second-generation polar orbiting meteorological satellite and was launched on November 15 2017. The satellite is currently the polar orbiting observation satellite with the highest spectral resolution in China. The number of measurement channels exceeds 7000 which will greatly improve the ability to detect power parameters thermal parameters and greenhouse gases in the lower atmosphere of the Earth. China will upgrade its capabilities in global numerical weather forecasting global climate change response ecological monitoring and space weather forecasting. It forms upper and afternoon network observations with Fengyun No. 3 C star and forms a high and low orbit with the stationary star to ensure the continuous and stable operation of China's meteorological satellites.
Earth in the Eyes of Meteorological Satellites 30000 kilometers away: Geological Unique ColorsThe Institute of Atmospheric Research Cooperation(CIRA) released a map of the Earth in real color and 'Geological color'. In the geological color the place covered by snow is white the ground under the moonlight is purple and the lights in most cities are yellow but the ground and shallow water areas under the sun look like their real color.   A stunning video recently released in Japan shows a 'geocolor' version of the earth from 22000 miles away. The video was taken by the Himawari-8 meteorological satellite managed by the Japan Meteorological Agency. The satellite is in synchronous orbit over the Pacific Ocean. Before the video was released a photo was released on February 10. The image also shows the real color of the earth. Scientists believe that this is the best portrait of the earth ever photographed.  Earlier this year Chali·laoaide a satellite imaging analyst used all the photos returned by the satellite within 24 hours of August 5 2015 to synthesize a circular film about 12 seconds long. The name is Glittering Blue. The images taken by the Himawari-8 satellite are centered on Japan. Other areas captured include the Western Pacific Australia parts of Asia Antarctica and Alaska.In a minute the sun rises five times from the western horizon moves eastward along the equator and then sets in the East. 'I tried to correct the color in the video to make it look like the Earth that astronauts saw on the edge of the satellite and had been adjusted by the human eye. '  The southern part of New Guinea and northern Australia are covered with turquoise colors where the water is shallower and you can see the bright sand below.According to Beijing time on February 18th foreign media reported that Japan recently shot a shocking video from 22000 miles(35400 kilometers) away presented a 'Geological' version of the earth.The video was taken by the Himawari-8 meteorological satellite managed by the Japan Meteorological Agency. The satellite is in synchronous orbit over the Pacific Ocean. As can be seen from the video the snow is covered in white the ground under the moonlight is purple and the lights in most cities are yellow but the ground and shallow water areas under the sun look like their real color.Before the video was released a photo was released on February 10. The image also shows the real color of the earth. Scientists believe that this is the best portrait of the earth ever photographed.It is reported that the natural color on the photo was restored by a new processing method called 'Simple Hybrid Contra Stretch'(SHCS). The technology was developed by the University of Wisconsin's Center for Scientific Engineering and the National Oceanic and Atmospheric Administration(NOAA). It uses a simple algorithm to synthesize four photos taken on different spectral bands(or on different frequencies of the electromagnetic spectrum) resulting in a photograph that restores the true color of the earth. And it is clearer than the real color pictures taken before.The Himawari-8 satellite can return real color photos every 10 minutes and at least one black and white photo can be returned every hour allowing meteorologists to better study weather systems such as convective clouds that will cause major storms. The accuracy of these pictures is about one-third of a mile(about 0.5 kilometers) which is twice the resolution of other meteorological satellites. However while true color is useful Geological color can better help scientists find unique geological features on Earth.The Institute of Atmospheric Research Cooperation(CIRA) released a map of the Earth in real color and 'Geological color'. 'Geological color technology provides us with a simple but visually powerful method that allows us to seamlessly connect multiple sources of information at both vertical and horizontal latitudes. 'The Institute of Atmospheric Research Cooperation said.'In the background of the geological color algorithm the adjustable scaling ratio allows R&D personnel to adjust the relative size of transparency in both dimensions. 'This technology can greatly improve the quality of standard visible and infrared satellite images. 'The Himawari-8 satellite is in synchronous orbit above the Earth so it can always stay in the same area above the Earth. For this satellite this area includes Australia Japan and other regions.The instrument used to take photos is the Advanced Himawari Imager(AHI) mounted on the satellite. The Himawari-8 actually has a 'twin brother' who uses it to observe East Asia and the Western Pacific. The next satellite Himawari-9 will be launched in 2016.The term 'true color' is not really appropriate because it is not the color of the earth that humans can see with the naked eye. Most of the earth photos we see are color-corrected to show the color of the earth in our eyes. But this photo in this article was taken on multiple spectral bands so it reflects the natural colors of the earth seen from space.Earlier this year Chali·laoaide a satellite imaging analyst used all the photos returned by the satellite within 24 hours of August 5 2015 to synthesize a circular film about 12 seconds long. The name is Glittering Blue.The images taken by the Himawari-8 satellite are centered on Japan. Other areas captured include the Western Pacific Australia parts of Asia Antarctica and Alaska. In a minute the sun rises five times from the western horizon moves eastward along the equator and then sets in the East. 'I tried to correct the color in the video to make it look like the Earth that astronauts saw on the edge of the satellite and had been adjusted by the human eye. ' said Lloyds.'My area of study is satellite imaging and if someone thinks what they see has been' tampered with 'I'm sensitive to this but ordinary cameras automatically make color adjustments. 'We can see on television that trees were uprooted in the storm utility poles were blown down electric cars were blown into the air and containers in the port were piled one by one. Typhoons mostly found in the South China sea and the Pacific often appeared in August accumulating power at warm seas and then weakening as they blew across the continent.Lloyd said that no satellite can show so much detail about the earth as the Himawari-8. Photographs taken by the satellite are centered on the equator and are concentrated near Jayapura in Indonesia. 'This angle is like being thrown around by a dancer. We can see their faces but the light is always unpredictable. ''The Himawari-8 satellite is much higher than the orbits of the International Space Station and the high-resolution imaging satellite which orbits just beyond the Earth's atmosphere. 'If the Earth is just as wide as 30 centimeters in the video the Himawari-8 satellite is located 85 centimeters away from it -- from this distance to your screen. It's like looking at the real earth from the Himawari-8 satellite. 'The amount of detail presented in the video is similar to what you can see with the naked eye. 'Why can't you see the city lights at night in the video?Chali·laoaide pointed out on his website that the satellite's camera is used to shoot in daylight. Direct sunlight is 10000 times brighter than the city street at night. Our eyes can adjust themselves but the Himawari-8 sensors can not.'If you 've ever shot with a hand bar imagine that the camera has a shutter speed of 1/500 an aperture f/8 ISO 10. Lloyd said: 'In the sun it can be exposed just right but at night you can't get a night view of the city. 'At night you may also be able to distinguish the city's night view from the orbit of the Himawari-8 satellite. But unless it is around midnight at the vernal equinox or the autumnal equinox and when the eclipse occurs you still can't see anything. 'At other times it's like lifting a piece of black paper toward the sun and trying to see a faint orange spot on the paper -- it's impossible to see anything. ' said Lloyds.
Gaofen5 satellite atmospheric environment observation load passed in-orbit test review The traditional monitoring of air environmental quality is mainly based on the observation points distributed in the near land and it is difficult to reflect the entire region. Satellite observation technology has been monopolized by foreign countries. Looking at the news Knews reporter learned that the three core payloads of atmospheric environment observation developed by the Anhui Institute of Optical Fine Mechanics of the Chinese Academy of Sciences and carried on the Gaofen 5 satellite recently passed the on-orbit test review organized by the Eighth Institute of Aerospace Science and Technology of China. It marks a new breakthrough in China's atmospheric environment observation technology.    The three atmospheric detection payloads were launched in May 2018 with Weixingchenggong on the 5th and boot imaging was achieved in the same month. The three payloads are the Atmospheric Trace Gas Differential Absorption Spectrometer(EMI) the Atmospheric Major Greenhouse Gas Monitor(GMI) and the Atmospheric aerosol Multi-Angle Polarization Sounder(DPC) which respectively undertake the observation tasks of polluting gases greenhouse gases and particulate matter pollution.        It is reported that in the past China's atmospheric environment monitoring relied on foreign satellite comprehensive observation data. Because it is not a real-time release of raw data accuracy and timeliness are difficult to guarantee. Sifuqi a researcher at the Anhui Institute of Light and Light Technology of the Chinese Academy of Sciences said that the three payloads can provide global rapid and accurate information on sensitive components of the Earth's atmosphere and can also analyze the process of generating transporting and dissipating surface pollution sources. It will play a positive role in promoting environmental monitoring and supervision emergency research and evaluation planning.The results of the review show that EMI has obtained the global distribution of trace gas nitrogen dioxide for the first time in China and its distribution characteristics are consistent with those of similar satellites in the world. The GHG spectral data obtained by GMI are consistent with the results of similar international satellite observations; DPC has acquired multi-spectral and multi-angle polarization images successfully inversion of aerosol optical thickness products and cloud phase classification products over the world's land and sea and has become the only satellite remote sensor that can use polarization technology to detect aerosols in orbit.
