Planetary Exploration Of China
The Planetary Exploration of China (PEC; ), also known as Tianwen (), is the robotic interplanetary spaceflight program conducted by the China National Space Administration (CNSA). The program aims to explore planets of the Solar System, starting from Mars, and will be expanded to Jupiter and more in the future. The program was initially known as the Mars mission of China at the early stage. It was later announced as Planetary Exploration of China in April 2020. The series of missions was named ''Tianwen''. The first mission of the program, Tianwen-1 Mars exploration mission, began on July 23, 2020. A spacecraft, which consisted of an orbiter, a lander, and a rover, was launched by a Long March 5 rocket from Wenchang. The Tianwen-1 was inserted into Mars orbit in February 2021 after a seven-month journey, followed by a successful soft landing of the lander and ''Zhurong'' rover on May 14, 2021, making China the second country in the world to successfully soft-land a fully opera ...

As the governing body of civil space activities, China National Space Administration does not execute any space program. The China Aerospace Science and Technology Corporation executes China's state space programs instead. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Model Of Phobos-Grunt Spacecraft 2011 P1110983
A model is an informative representation of an object, person or system. The term originally denoted the plans of a building in late 16th-century English, and derived via French and Italian ultimately from Latin ''modulus'', a measure. Models can be divided into physical models (e.g. a model plane) and abstract models (e.g. mathematical expressions describing behavioural patterns). Abstract or conceptual models are central to philosophy of science, as almost every scientific theory effectively embeds some kind of model of the physical or human sphere. In commerce, "model" can refer to a specific design of a product as displayed in a catalogue or show room (e.g. Ford Model T), and by extension to the sold product itself. Types of models include: Physical model A physical model (most commonly referred to simply as a model but in this context distinguished from a conceptual model) is a smaller or larger physical copy of an object. The object being modelled may be small (for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heavenly Questions
The ''Heavenly Questions'' or ''Questions to Heaven'' () is a piece contained in the Classical Chinese poetry collection of ''Chu Ci'', which is noted both in terms of poetry and as a source for information on the ancient culture of China, especially the area of the ancient state of Chu. Of all the poems attributed to Qu Yuan, "Tianwen" contains more myths than any of the other pieces which may be attributed to him; however, due to the formal structure of "Tianwen" as a series of questions, information regarding the myths alluded to appear more as a series of allusive fragments than as cohesively narrated stories. According to legend, Qu Yuan wrote this series of questions in verse after viewing various scenes depicted on temple murals; specifically, it is said that following his exile from the royal court of Chu, Qu Yuan looked upon the depictions of the ancestors and the gods painted upon the walls of the ancestral temple of Chu; and, then, in response, wrote his questions to ...

Martian Surface
The study of surface characteristics (or surface properties and processes) is a broad category of Mars science that examines the nature of the materials making up the Martian surface. The study evolved from telescopic and remote-sensing techniques developed by astronomers to study planetary surfaces. However, it has increasingly become a subdiscipline of geology as automated spacecraft bring ever-improving resolution and instrument capabilities. By using characteristics such as color, albedo, and thermal inertia and analytical tools such as reflectance spectroscopy and radar, scientists are able to study the chemistry and physical makeup (e.g., grain sizes, surface roughness, and rock abundances) of the Martian surface. The resulting data help scientists understand the planet's mineral composition and the nature of geological processes operating on the surface. Mars’ surface layer represents a tiny fraction of the total volume of the planet, yet plays a significant role in the pla ...

Space
Space is the boundless three-dimensional extent in which objects and events have relative position and direction. In classical physics, physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework. Debates concerning the nature, essence and the mode of existence of space date back to antiquity; namely, to treatises like the ''Timaeus'' of Plato, or Socrates in his reflections on what the Greeks called ''khôra'' (i.e. "space"), or in the ''Physics'' of Aristotle (Book IV, Delta) in the definition of ''topos'' (i.e. place), or in the later "geometrical conception of place" as "spac ...

4179 Toutatis
4179 Toutatis, provisional designation , is an elongated, stony asteroid and slow rotator, classified as a near-Earth object and potentially hazardous asteroid of the Apollo asteroid and Alinda asteroid groups, approximately 2.5 kilometers in diameter. Discovered by French astronomer Christian Pollas at Caussols in 1989, the asteroid was named after Toutatis from Celtic mythology. Toutatis is also a Mars-crosser asteroid with a chaotic orbit produced by a 3:1 resonance with the planet Jupiter, a 1:4 resonance with the planet Earth, and frequent close approaches to the terrestrial planets, including Earth. In December 2012, Toutatis passed within about 18 lunar distances of Earth. The Chinese lunar probe Chang'e 2 flew by the asteroid at a distance of 3.2 kilometers and a relative velocity of 10.73 km/s. Toutatis approached Earth again in 2016, but will not make another notably close approach until 2069. Properties Toutatis was first sighted on 10 February 1934, a ...

Chang'e 2
Chang'e 2 (; ) is a Chinese unmanned lunar probe that was launched on 1 October 2010. It was a follow-up to the Chang'e 1 lunar probe, which was launched in 2007. Chang'e 2 was part of the first phase of the Chinese Lunar Exploration Program, and conducted research from a 100-km-high lunar orbit in preparation for the December 2013 soft landing by the Chang'e 3 lander and rover. Chang'e 2 was similar in design to Chang'e 1, although it featured some technical improvements, including a more advanced onboard camera. Like its predecessor, the probe was named after Chang'e, an ancient Chinese moon goddess. After completing its primary objective, the probe left lunar orbit for the Earth–Sun Lagrangian point, to test the Chinese tracking and control network, making the China National Space Administration the third space agency after NASA and ESA to have visited this point. It entered orbit around L2 on 25 August 2011, and began transmitting data from its new position in September 201 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
