Dongfanghong Program
Dongfanghong () was a satellite program of the People's Republic of China. The program started in August 1965 as Project 651—a less ambitious successor to the earlier Project 581—with the goal of launching a satellite heavier than both Sputnik 1 and Explorer 1 into space, and developing all the necessary technologies to do so. History In 1958, the Chinese Academy of Science proposed Project 581 which included a plan to launch a satellite into space before 1 October 1959. The project was troubled due to the country's lack of expertise in the field of rocketry. On 21 January 1959, Zhang Jingfu, who was in charge in the satellite research program, postponed the project to allow effort to be put into developing more basic technologies, such as sounding rocketry. In December 1964, during the 3rd National People's Congress, Zhao Jiuzhang suggested that the work on satellites be resumed. In August 1968, the Central Special Committee approved Chinese Academy of Science's plan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Satellite
A satellite or artificial satellite is an object intentionally placed into orbit in outer space. Except for passive satellites, most satellites have an electricity generation system for equipment on board, such as solar panels or radioisotope thermoelectric generators (RTGs). Most satellites also have a method of communication to ground stations, called transponders. Many satellites use a standardized bus to save cost and work, the most popular of which is small CubeSats. Similar satellites can work together as a group, forming constellations. Because of the high launch cost to space, satellites are designed to be as lightweight and robust as possible. Most communication satellites are radio relay stations in orbit and carry dozens of transponders, each with a bandwidth of tens of megahertz. Satellites are placed from the surface to orbit by launch vehicles, high enough to avoid orbital decay by the atmosphere. Satellites can then change or maintain the orbit by pr ...

Sputnik 1
Sputnik 1 (; see § Etymology) was the first artificial Earth satellite. It was launched into an elliptical low Earth orbit by the Soviet Union on 4 October 1957 as part of the Soviet space program. It sent a radio signal back to Earth for three weeks before its three silver-zinc batteries ran out, and continued in orbit for three months until aerodynamic drag caused it to fall back into the atmosphere on 4 January 1958. It was a polished metal sphere in diameter with four external radio antennas to broadcast radio pulses. Its radio signal was easily detectable by amateur radio operators, and the 65° orbital inclination made its flight path cover virtually the entire inhabited Earth. The satellite's unanticipated success precipitated the American Sputnik crisis and triggered the Space Race, part of the Cold War. The launch was the beginning of a new era of political, military, technological and scientific developments. The word ''sputnik'' is Russian for ''satellite ...

Explorer 1
Explorer 1 was the first satellite launched by the United States in 1958 and was part of the U.S. participation in the International Geophysical Year (IGY). The mission followed the first two satellites the previous year; the Soviet Union's Sputnik 1 and Sputnik 2, beginning the Cold War Space Race between the two nations. Explorer 1 was launched on 1 February 1958 at 03:47:56 GMT (or 31 January 1958 at 22:47:56 Eastern Time) atop the first Juno booster from LC-26A at the Cape Canaveral Missile Test Center of the Atlantic Missile Range (AMR), in Florida. It was the first spacecraft to detect the Van Allen radiation belt, returning data until its batteries were exhausted after nearly four months. It remained in orbit until 1970. Explorer 1 was given Satellite Catalog Number 00004 and the Harvard designation 1958 Alpha 1, the forerunner to the modern International Designator. Background The U.S. Earth satellite program began in 1954 as a joint U.S. Army and U. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sounding Rocket
A sounding rocket or rocketsonde, sometimes called a research rocket or a suborbital rocket, is an instrument-carrying rocket designed to take measurements and perform scientific experiments during its sub-orbital flight. The rockets are used to launch instruments from 48 to 145 km (30 to 90 miles) above the surface of the Earth, the altitude generally between weather balloons and satellites; the maximum altitude for balloons is about 40 km (25 miles) and the minimum for satellites is approximately 121 km (75 miles). Certain sounding rockets have an apogee between 1,000 and 1,500 km (620 and 930 miles), such as the Black Brant X and XII, which is the maximum apogee of their class. Sounding rockets often use military surplus rocket motors. NASA routinely flies the Terrier Mk 70 boosted Improved Orion, lifting 270–450-kg (600–1,000-pound) payloads into the exoatmospheric region between 97 and 201 km (60 and 125 miles).

The East Is Red (song)
"The East Is Red" is a Chinese revolutionary song that was the ''de facto'' national anthem of the People's Republic of China during the Cultural Revolution in the 1960s. The lyrics of the song were attributed to Li Youyuan (李有源), a farmer from Shaanbei (northern Shaanxi province), and the melody was derived from a local peasant love song from the Loess Plateau entitled "Bai Ma Diao" 《白马调》 (White Horse Tune), also known as "Zhima You" 《芝麻油》 (Sesame Oil), which was widely circulated in the area around Yan'an in the 1930s. The farmer allegedly got his inspiration upon seeing the rising sun in the morning of a sunny day. History Early history The lyrics to "The East Is Red" were adapted from an old Shaanxi folk song about love. The lyrics were often changed depending on the singer. The modern lyrics were produced in 1942, during the Second Sino-Japanese War, attributed to a farmer from northern Shaanxi, Li Youyuan. It is possible there was an earli ...
