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 ...

Mars Launch Window
The planet Mars has been explored remotely by spacecraft. Probes sent from Earth, beginning in the late 20th century, have yielded a large increase in knowledge about the Martian system, focused primarily on understanding Geology of Mars, its geology and Planetary habitability, habitability potential. Engineering Interplanetary spaceflight, interplanetary journeys is complicated and the exploration of Mars has experienced a high failure rate, especially the early attempts. Roughly sixty percent of all spacecraft destined for Mars failed before completing their missions and some failed before their observations could begin. Some missions have met with unexpected success, such as the twin Mars Exploration Rovers, ''Spirit (rover), Spirit'' and ''Opportunity (rover), Opportunity'' which operated for years beyond their specification. Current status , there are three operational rovers on the surface of Mars, the Curiosity (rover), ''Curiosity'' and Perseverance (rover), ''Persever ...

List Of Artificial Objects On Mars
The following table is a partial list of artificial objects on the surface of Mars, consisting of spacecraft which were launched from Earth. Although most are defunct after having served their purpose, the ''Curiosity'' rover, ''Perseverance'' rover, ''Ingenuity'' helicopter, and ''Zhurong'' rover are all active. China's Tianwen-1 spacecraft is the most recent artificial object to land safely on Mars, with Mars 3 and ''Tianwen-1 remote camera'' the heaviest and lightest Martian spacecraft respectively. The table does not include smaller objects, such as springs, fragments, parachutes and heat shields. , there are 14 missions with objects on the surface of Mars. Some of these missions contain multiple spacecraft. List of landers and vehicles In this listing, it is implied that each mission left debris according to its design. For example, the ''Schiaparelli'' EDM lander likely exploded on impact, creating an unknown number of fragments at one location. At another location, the ...

Wenchang Spacecraft Launch Site
The Wenchang Space Launch Site ( zh, 文昌航天发射场, links=no), located in Wenchang, Hainan, China, is a rocket launch site — one of the two spacecraft launch sites of Xichang Satellite Launch Center (the other site is in Xichang, Sichuan). It is a former suborbital test center. It is China's fourth and southernmost space vehicle launch facility (spaceport). It has been specially selected for its low latitude, which is only 19° north of the equator, allowing for the increase in payload necessary for launching China's future space station. It is capable of launching the Long March 5, currently the most powerful Chinese rocket. Unlike the space centers on the mainland, whose rail tracks are too narrow to transport the new five meter core boosters, Wenchang uses its sea port for deliveries. Initial launches of the CZ-5 booster from Wenchang were expected to start in 2014, one year after the intended commissioning of the Wenchang Launch Site. However, the first lau ...

Mars Landing
A Mars landing is a landing of a spacecraft on the surface of Mars. Of multiple attempted Mars landings by robotic, uncrewed spacecraft, ten have had successful soft landings. There have also been studies for a possible human mission to Mars, including a landing, but none have been attempted. Soviet Union’s Mars 3, which landed in 1971, was the first successful Mars landing. As of May 2021, the Soviet Union, United States, and China have conducted Mars landings successfully. Methods of descent and landing As of 2021, all methods of landing on Mars have used an aeroshell and parachute sequence for Mars atmospheric entry and descent, but after the parachute is detached, there are three options. A stationary lander can drop from the parachute back shell and ride retrorockets all the way down, but a rover cannot be burdened with rockets that serve no purpose after touchdown. One method for lighter rovers is to enclose the rover in a tetrahedral structure which in turn is encl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Utopia Planitia
Utopia Planitia (Greek and Latin: "Nowhere Land Plain") is a large plain within Utopia, the largest recognized impact basin on Mars and in the Solar System with an estimated diameter of . It is the Martian region where the ''Viking 2'' lander touched down and began exploring on September 3, 1976, and the ''Zhurong'' rover touched down on 14 May, 2021, as a part of the Tianwen-1 mission. It is located at the antipode of Argyre Planitia, centered at . It is also in the Casius quadrangle, Amenthes quadrangle, and the Cebrenia quadrangle of Mars. Many rocks at Utopia Planitia appear perched, as if wind removed much of the soil at their bases. A hard surface crust is formed by solutions of minerals moving up through soil and evaporating at the surface. Some areas of the surface exhibit scalloped topography, a surface that looks like it was carved out by an ice cream scoop. This surface is thought to have formed by the degradation of an ice-rich permafrost. Many features that look lik ... [...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 ...

Long March 5
Long March 5 (LM-5; zh, s=长征五号 , p=Chángzhēng wǔ hào), or Changzheng 5 (CZ-5), and also by its nickname "''Pang-Wu''" (胖五, "''Fat-Five''"), is a Chinese heavy-lift launch vehicle developed by the China Academy of Launch Vehicle Technology (CALT). It is the first Chinese launch vehicle designed to use exclusively non-hypergolic liquid propellants. It is the fifth iteration of the Long March rocket family. There are currently two CZ-5 variants: CZ-5 and CZ-5B. The maximum payload capacities are approximately to low Earth orbit (for CZ-5B) and approximately to geostationary transfer orbit (for CZ-5). As of 2021, a 3-core human-rated variant, referred to as CZ-5G, designed for manned moon mission, is under development; this variant will be capable of launching a crewed spacecraft into lunar orbit. The Long March 5 roughly matches the capabilities of American NSSL heavy-lift launch vehicles such as the Delta IV Heavy. It is currently the most powerful member of ...

Mars
Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System, only being larger than Mercury (planet), Mercury. In the English language, Mars is named for the Mars (mythology), Roman god of war. Mars is a terrestrial planet with a thin atmosphere (less than 1% that of Earth's), and has a crust primarily composed of elements similar to Earth's crust, as well as a core made of iron and nickel. Mars has surface features such as impact craters, valleys, dunes and polar ice caps. It has two small and irregularly shaped moons, Phobos (moon), Phobos and Deimos (moon), Deimos. Some of the most notable surface features on Mars include Olympus Mons, the largest volcano and List of tallest mountains in the Solar System, highest known mountain in the Solar System and Valles Marineris, one of the largest canyons in the Solar System. The North Polar Basin (Mars), Borealis basin in the Northern Hemisphere covers approximately 40% of the planet and may be a la ...

Lander (spacecraft)
A lander is a spacecraft that descends towards, comes to rest on, the surface of an astronomical body. In contrast to an impact probe, which makes a hard landing that damages or destroys the probe upon reaching the surface, a lander makes a soft landing after which the probe remains functional. For bodies with atmospheres, the landing occurs after atmospheric entry. In these cases, landers may employ parachutes to slow them down enough to maintain a low terminal velocity. In some cases, small landing rockets will be fired just before impact in order to reduce the lander's velocity. Landing may be accomplished by controlled descent and set down on landing gear, with the possible addition of a post-landing attachment mechanism (such as the mechanism used by ''Philae'') for celestial bodies with low gravity. Some missions (for example, Luna 9 and Mars Pathfinder) used inflatable airbags to cushion the lander's impact rather than utilizing more traditional landing gear. When a hi ...
