Shenzhou 4
Shenzhou 4 () – launched on December 29, 2002 – was the fourth uncrewed launch of the Chinese Shenzhou spacecraft. Two dummy astronauts were used to test the life support systems (a live astronaut was not used until Shenzhou 5 on October 15, 2003). The spacecraft was equipped for a crewed flight, even featuring a sleeping bag, food, and medication. The windows were constructed of a new material that was designed to stay clear even after reentry to allow an astronaut to confirm that the parachutes have deployed properly. It was said that the spacecraft flown on Shenzhou 4 had no major differences to that used on Shenzhou 5. It flew with the ability for manual control and emergency landing, systems needed for a crewed flight. A week before the launch, astronauts trained in the spacecraft to familiarise themselves with its systems. Initially the spacecraft was in a by orbit inclined at 42.4°. This was raised to by at 23:35 UTC on December 29, 2002. On January 4 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shenzhou (spacecraft)
Shenzhou (, ; see ) is a spacecraft developed and operated by China to support its crewed spaceflight program, China Manned Space Program. Its design resembles the Russian Soyuz spacecraft, but it is larger in size. The first launch was on 19 November 1999 and the first crewed launch was on 15 October 2003. In March 2005, an asteroid was named 8256 Shenzhou in honour of the spacecraft. Etymology The literal meaning of the native name ( p: Shénzhōu; ) is "the Divine vessel n the Heavenly River, to which Heavenly River () means the Milky Way in Classical Chinese. is a pun and neologism that plays on the names of China, poetic word referring to China, , meaning ''Divine realm'', which bears the same pronunciation. For further information, refer to Chinese theology, Chinese astronomy and names of China. History China's first efforts at human spaceflight started in 1968 with a projected launch date of 1973. Although China successfully launched an uncrewed satellite in 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Li Peng
Li Peng (; 20 October 1928 – 22 July 2019) was a Chinese politician who served as the fourth Premier of the People's Republic of China from 1987 to 1998, and as the Chairman of the Standing Committee of the National People's Congress, China's top legislative body, from 1998 to 2003. For much of the 1990s Li was ranked second in the Chinese Communist Party (CCP) hierarchy behind then Party General Secretary Jiang Zemin. He retained his seat on the CCP Politburo Standing Committee until his retirement in 2002. Li was the son of an early Communist revolutionary, Li Shuoxun, who was executed by the Kuomintang. After meeting Zhou Enlai in Sichuan, Li was raised by Zhou and his wife, Deng Yingchao. Li trained to be an engineer in the USSR and worked at an important national power company after returning to China. He escaped the political turmoil of the 1950s, '60s and '70s due to his political connections and his employment in the company. After Deng Xiaoping became China's lea ...

Physics
Physics is the natural science that studies matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. "Physical science is that department of knowledge which relates to the order of nature, or, in other words, to the regular succession of events." Physics is one of the most fundamental scientific disciplines, with its main goal being to understand how the universe behaves. "Physics is one of the most fundamental of the sciences. Scientists of all disciplines use the ideas of physics, including chemists who study the structure of molecules, paleontologists who try to reconstruct how dinosaurs walked, and climatologists who study how human activities affect the atmosphere and oceans. Physics is also the foundation of all engineering and technology. No engineer could design a flat-screen TV, an interplanetary spacecraft, or even a better mousetrap without first understanding the basic laws of physic ...

Weightlessness
Weightlessness is the complete or near-complete absence of the sensation of weight. It is also termed zero gravity, zero G-force, or zero-G. Weight is a measurement of the force on an object at rest in a relatively strong gravitational field (such as on the surface of the Earth). These weight-sensations originate from contact with supporting floors, seats, beds, scales, and the like. A sensation of weight is also produced, even when the gravitational field is zero, when contact forces act upon and overcome a body's inertia by mechanical, non-gravitational forces- such as in a centrifuge, a rotating space station, or within an accelerating vehicle. When the gravitational field is non-uniform, a body in free fall experiences tidal effects and is not stress-free. Near a black hole, such tidal effects can be very strong. In the case of the Earth, the effects are minor, especially on objects of relatively small dimensions (such as the human body or a spacecraft) and the overa ...

Seed
A seed is an embryonic plant enclosed in a protective outer covering, along with a food reserve. The formation of the seed is a part of the process of reproduction in seed plants, the spermatophytes, including the gymnosperm and angiosperm plants. Seeds are the product of the ripened ovule, after the embryo sac is fertilized by sperm from pollen, forming a zygote. The embryo within a seed develops from the zygote, and grows within the mother plant to a certain size before growth is halted. The seed coat arises from the integuments of the ovule. Seeds have been an important development in the reproduction and success of vegetable gymnosperm and angiosperm plants, relative to more primitive plants such as ferns, mosses and liverworts, which do not have seeds and use water-dependent means to propagate themselves. Seed plants now dominate biological niches on land, from forests to grasslands both in hot and cold climates. The term "seed" also has a general me ...

Peony
The peony or paeony is a flowering plant in the genus ''Paeonia'' , the only genus in the family Paeoniaceae . Peonies are native to Asia, Europe and Western North America. Scientists differ on the number of species that can be distinguished, ranging from 25 to 40, although the current consensus is 33 known species. The relationships between the species need to be further clarified. Most are herbaceous perennial plants tall, but some are woody shrubs tall. They have compound, deeply lobed leaves and large, often fragrant flowers, in colors ranging from purple and pink to red, white or yellow, in late spring and early summer. The flowers have a short blooming season, usually only 7–10 days. Peonies are popular garden plants in temperate regions. Herbaceous peonies are also sold as cut flowers on a large scale, although generally only available in late spring and early summer. Description Morphology All Paeoniaceae are herbaceous perennials or deciduous shrubs, with t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
People's Liberation Army
The People's Liberation Army (PLA) is the principal military force of the People's Republic of China and the armed wing of the Chinese Communist Party (CCP). The PLA consists of five service branches: the Ground Force, Navy, Air Force, Rocket Force, and Strategic Support Force. It is under the leadership of the Central Military Commission (CMC) with its chairman as commander-in-chief. The PLA can trace its origins during the Republican Era to the left-wing units of the National Revolutionary Army (NRA) of the Kuomintang (KMT) when they broke away on 1 August 1927 in an uprising against the nationalist government as the Chinese Red Army before being reintegrated into the NRA as units of New Fourth Army and Eighth Route Army during the Second Sino-Japanese War. The two NRA communist units were reconstituted into the PLA on 10 October 1947. Today, the majority of military units around the country are assigned to one of five theater commands by geographical location. ...
