November 27, 2009 China successfully achieved space drift for the first time in static meteorological satellite double star position exchange
China Fengyun-2 E star achieved space drift and has successfully replaced Fengyun-2 C star. National Satellite Meteorological Center said on November 27, 2009 that this is the first time in the history of China's static meteorological satellites that have successfully achieved dual-star position exchange and business succession.
At present, China's on-orbit business has reached three stationary meteorological satellites. Fengyun-2 C star has been operating stably for nearly five years, exceeding its three-year design life. On October 22, Fengyun-2 E star officially began to drift. After thirty days of drift, Fengyun-2 E star successfully drifted from 123:5 degrees east longitude to around 103:00 octave, and will conduct dual-star network observations with D star. Star C began to drift at 9:00 on November 15, and is expected to reach its original position in two months. After the fixed point is successful, it will use the remaining fuel to carry out observations and special tests within its capacity.

1981 November 27, 1981 Egyptian Desert found huge underground river valley
11 November 27, 1981 Great underground river valley was found under the Egyptian desert
111 November 27, 1981 During the second test flight of the US "Columbia" space shuttle , a huge underground river valley submerged in the desert in southwestern Egypt was discovered through a telemetry system. This discovery aroused great interest from Egyptian scientists.
This desert area has only rained for more than 40 years. The signal from the space shuttle telemetry system can penetrate the dry sand layer at a depth of 4.6 meters, so this discovery has been obtained. According to this discovery, this deserted and drier desert in the world is a region with fertile land, good weather and prosperous people and animals 20,000 to 50,000 years ago. There were some huge rivers connecting Egypt and Sudan . Under this desert, there is an underground valley that is 25 times larger than the size of the Nile basin, with the width of the valley reaching 25 to 30 kilometers. As the years changed, the desert gradually covered these rivers and valleys. Some scientists believe that the lives of the ancient Egyptians began in this desert area and later moved to the Nile River Basin.

November 27, 1961 The Soviet Union made the world's first lunar globe
lunar globe records the distribution of sea and land, mountains, rivers, lakes and swamps on the moon. Although there is no water on the moon, these nouns have been used all the time, and
has only symbolic meaning. Since the Italian astronomer Galileo used a telescope to observe the moon in 1610, he has gradually discovered various characteristics on the moon, so people and place names have begun to appear on the moon. In the past 400 years, the moon has become a "little earth" full of people and place names on the earth. Now, according to international unified naming, a lunar globoscope has been made based on these naming and charts. Like the maps and place names printed on the globoscope, we have a solid foundation. We also design and print the lunar globoscope based on scientific data shared internationally, which is accurate and correct.

1958 November 27, 1958 my country's first 10,000-ton ocean-going ship launched
On November 27, 1958, the first 10,000-ton ocean-going cargo ship built by , Dalian Shipyard, was launched. The Ministry of Transportation named this ocean-going cargo ship "Leaping". The huge hull of
, the Soviet Union, was officially laid on the ship platform on the eve of National Day this year. It took only 58 days to be completed and launched on November 27. This speed is very fast. According to known materials: Britain, which has a history of more than 100-year shipbuilding history, the current construction period for 10,000-ton freighter is six months; Japan, which currently has the highest shipbuilding speed in the world, has the shortest average shipbuilding cycle for 10,000-ton freighter.
