(1) There is an asteroid belt consisting of hundreds of thousands of asteroids between the red Mars and the huge Jupiter orbit. These asteroids are actually a group of rubble of different sizes. The largest diameter can reach Qian Qian meters, and the smallest is only a few meters or dozens of meters. Like the eight planets, these asteroids revolve around the sun day and night. How did these mysterious asteroids form? What cosmic information do they contain? These problems have always attracted the attention of scientists. Visiting asteroids has also become one of the important purposes of scientists' space exploration.
② On February/February/200 12, the unmanned probe "Near-Earth Asteroid Dating" of the United States successfully landed on the asteroid family Eros for the first time in human history.
(3) eros, named after the ancient Greek god of love, is a very common asteroid in the asteroid family. It is actually a big stone, shaped like a potato, 34 kilometers long, 13 kilometers wide and 14 kilometers thick, about 3160,000 kilometers away from the earth. The asteroid Cupid also orbits the sun, but its gravity is only one thousandth of that of the earth. It is conceivable that the accuracy of landing on such an asteroid with minimal gravity is so high that the experts in charge of this exploration have not made a plan to land on the asteroid.
④ The unmanned probe "Near-Earth Asteroid Dating" was launched by the United States in February 1996. After four years of space flight, it successfully entered the orbit of the asteroid "Eros" on February 14, 2000, and began to detect it. In less than a year, the detector has sent back about 6.5438+600,000 photos of the asteroid rock surface.
⑤ The detector has been running in an orbit 24 kilometers away from Eros for nearly a year, and has gradually exhausted its own fuel. At this time, it finally made an amazing move: it launched the final sprint to the "God of Love" star that it "paid attention to" for a year. After two rocket launches, the probe left the orbit of Eros, slowly landed on its surface, and finally landed on the barren and rugged star surface of Eros. The whole process lasted four and a half hours. Scientists are even more delighted that this is a "scientific dividend"; In addition, the landing site is also an area that scientists are most interested in: there is a lack of craters, but there are a lot of rocks and ditch marks.
⑥ "Near-Earth Asteroid Dating" is one of the first probes with robot function developed by NASA. After analyzing the photos it sent back, scientists pointed out that "Eros" contains the most primitive substances in the solar system, and measured the density, chemical composition and magnetic field of asteroids. The successful landing did not damage the equipment on the probe, so that the probe could continue to send signals to the earth within three months to further understand the mystery of the asteroid. With the mystery of asteroids uncovered, human beings will have a clearer understanding of the origin and evolution of the solar system and even the evolution of the universe.

The new video era is coming.
AK Since the mid-1990s, streaming media technology has started on the Internet. After the development of 10 years, webcasting has become an independent concept and branch.
An important change brought by the development of network video is that the computer is becoming the second TV set in the family. With the development of digital technology, wireless transmission between computer and TV content can be realized through converters. At that time, no matter at home or in the office, the video content in the computer can be transmitted to the TV, and the content played by the TV can also be transmitted to the computer, which makes the boundary between the computer and the TV more and more blurred. On June 5438+ 10, 2007, Apple Computer Company of the United States launched "Apple TV" to build a bridge between computers and televisions for users.
From the perspective of future development, the mobile phone screen will soon become an important third screen for watching videos. The realization of mobile TV is mainly through wireless mobile communication, terrestrial radio broadcasting and the combination of satellite and terrestrial supplementary points. The latter two methods are both digital multimedia broadcasting (DMB) methods. China Radio and Television System is committed to providing mobile terminal video services for the 2008 Beijing Olympic Games, and vigorously promoting terrestrial DMB. In 2006, terrestrial DMB was launched in Beijing, Shanghai and Guangdong, and the mobile TV market and emerging industries in China began to take shape.
In the new video era, the production and dissemination of video content is no longer the "patent" of TV media, especially after the Internet enters Web2. 0 stage, the rise of podcasts and video sharing websites has created a dazzling new pattern of video communication. It is tens of thousands of netizens in Qian Qian who browse websites and create blogs, podcasts, video sharing websites and dating websites, which makes the network information explode and pushes the online media into the era of mass dominance.
In the new video era, TV media should be positioned as "producers, providers and operators of digital video content", and cooperate and compete with other kinds of digital new media with an open mind to achieve win-win development in the future.

Three Gorges Museum

commentator
① The Three Gorges Museum is located at the west end of the Great Hall of the People in Chongqing. The main building is157.3m long, 98.085m wide and 32m high, with a total construction area of over 40,000 square meters. The appearance of this building itself carries many historical and cultural connotations.
(2) The Three Gorges Museum is built on the mountain, showing a big arc. Seen from People's Square, this museum looks like the majestic Three Gorges Dam on the Yangtze River. The most conspicuous appearance of the museum is a large area of curved blue glass curtain wall and a simple and square sandstone exterior wall. Blue glass symbolizes water, and sandstone exterior wall represents mountains, which embodies the characteristics of Chongqing's landscape city. Directly above the museum is a funnel-shaped dome, which looks like a huge dew tray. On the one hand, it means "the water of the Three Gorges falls from the sky"; On the other hand, the water flows down the three-level waterfall and connects with the People's Square, which embodies the implication that the Three Gorges Museum accepts the water of ancestral culture and moistens the earth with culture.
③ The exhibition hall of the Three Gorges Museum covers an area of 23,225 square meters and has four basic exhibitions, namely the "Magnificent Three Gorges" reflecting the history, culture and spirit of the Three Gorges; Far from Cuba and Chongqing reflects the origin of Chongqing's local history and culture; "Chongqing urban road" reflecting the changes in Chongqing in the 20th century: "Anti-Japanese War years" reflecting Chongqing's anti-Japanese war culture. Here we focus on the first two exhibition halls.
④ The "Magnificent Three Gorges" exhibition hall is located on the right side of the first floor of the Three Gorges Museum, which is the signature exhibition hall of the museum. Walking into the exhibition hall, visitors seem to have come to the magnificent Qutang Gorge. Face to face is a 9-meter-long and 6-meter-high Three Gorges mural, which, together with various properly placed Three Gorges stones, constitutes a magnificent Kuimen and a beautiful Taofeng. At this moment, tourists are stepping on a Yangtze River water made of glass water barriers. The sound of the river lapping on the shore, the sound of the trumpet of the Chuanjiang River and the unique ape cry of the Three Gorges of the Yangtze River constitute a truly magnificent Three Gorges.
⑤ There are a lot of natural Three Gorges stones in the "Magnificent Three Gorges" exhibition hall. The waterfall stone at the mouth of Qutang Gorge, the black stone in the middle of Qutang Gorge, the silk stone and silk road cut by Wuxia Gorge, and the inscription of Baiheliang, known as the "world's first ancient hydrological station", were also partially cut and moved into the exhibition hall. At present, there is no precedent for museums all over the country to put such large-scale natural stones in it.
⑥ Compared with the magnificent Three Gorges exhibition hall, the Far Cuba and Chongqing exhibition hall is simple and heavy. The "Far Cuba and Chongqing" exhibition hall is located on the left side of the second floor of the Three Gorges Museum, with an exhibition area of 1 160 square meters and more than 1000 exhibits. This is the exhibition hall with the richest cultural relics in the Three Gorges Museum. More than 80% of the cultural relics are new archaeological discoveries of the Three Gorges in Chongqing since 1997. This is the first time it has been made public, such as the teeth and mandible fossils of Wushan people unearthed in Longgupo, the saber-toothed stone carvings found in Xinglong Cave site, the pottery pieces found in Yuwupu, Fengjie, and the bird-shaped statue unearthed in Xiaotian Creek. This exhibition hall mainly relies on cultural relics to show the objective existence and infinite charm of ancient Bayu culture.
