Quote:The S-IB stage was built by the Chrysler corporation at the Michoud Assembly Facility, New Orleans. It was powered by eight Rocketdyne H-1 rocket engines burning RP-1 fuel with liquid oxygen (LOX). Eight Redstone tanks (four holding fuel and four holding LOX) were clustered around a Jupiter rocket LOX tank. The four outboard engines were mounted on gimbals, allowing them to be steered to control the rocket. Eight fins surrounding the base thrust structure provided aerodynamic stability and control.

BTW rocket engines are a Western invention....
Quote:World's First Rocket Made in Korea
Pyongyang, May 30 (KCNA) -- "Rocket" weapons were made and used by Korea already in the period of Koguryo (B.C. 277-A.D. 668). The first "rocket" was very simple but its principle is similar with that of modern one.
A jet-propelled weapon called Kwanghwi demonstrated its might in a battle near the castle in Mt. Pukhan in 661.
People of Koryo (918-1392) made a "rocket" called Hwajon.
Hwajon was 726 millimeters long and its arrowhead 90 millimeters long. The arrow was shot by lighting the cartridge.
According to a historical record, Koryo manufactured lots of Hwajon around 1127 and deployed them in vantage points for national defence.
On the basis of arrows with fire wicks made in the period of the three kingdoms, Koreans developed Singijon, the origin of multistage rocket, in the early 15th century.
There were three kinds of Singijon according to their sizes, types and powder-cartridges.
The small one was a two-stage rocket. The medium one with one more small cartridge than the small one was a three-stage rocket, while the large one with four cartridges and wings was a four-stage rocket.
Having a great firing power, they could strike far-off targets on land and big warships. The weapons were widely used during the Imjin Patriotic War (1592) against the Japanese invaders and other battles against invaders. They were also used as signal means.
They are precious historical relics showing the intelligence and patriotism of the Korean nation.
Quote:Singijon, Origin of Multi-stage Rocket
Pyongyang, October 23 (KCNA) -- The Korean people made a jet-propelled weapon for the first time in the world.
Kwanghwi, which had the same operating principle with rocket, came into being in the period of Koguryo (B.C. 277-A.D. 668), and Singijon, the origin of multi-stage rocket, appeared in the early 15th century.
Singijon was classified into small, medium and large one according to its size, type and structure of reaction powder-flask.
The small-sized Singijon was a kind of two-stage rocket as it could fly far to a distance by the force of gas emitted from two powder-flasks installed in the tail of an arrow.
The other two weapons equipped with more powder-flasks could fly like three-stage and four-stage rockets.
In the mid-15th century, dimensions of Singijon were standardized on a nationwide scale.
This weaponry was used in the battles of Kyongju and Haengjusan castles during the Imjin Patriotic War (1592-1598). -0-

One of these is a Shenzhou spaceship and the other is a Soyuz.
How many people on PDF think they don't look alike??
You really think you pulled space travel off all by your smart selves...um..think again.
Quote:Soyuz Design Stolen From General Electric Apollo Proposal
There was something awfully familiar looking about the Soyuz spacecraft, the most successful in history....
Is the Soyuz Design a Copy of the General Electric Apollo Proposal?
The Russian Soyuz spacecraft has been the longest-lived, most adaptable, and most successful manned spacecraft design. In production for over thirty years, more than 220 have been built and flown on a wide range of missions. The design will remain in use with the international space station well into the next century.
But did the Russians steal the design from the Americans? When the configuration was first revealed in 1968, some industry insiders immediately noticed a strong resemblance to General Electric's losing Apollo spacecraft proposal. The resemblance was openly discussed by Phillip S Clark and Ralph F Gibbons in 1983. After the Soviet lunar program was declassified, and information on the design of the Soyuz lunar orbiter version was revealed, the similarities seemed even more marked.

Quote:Iran can learn from China about sci-fi movies: Reza Mirkarimi
November 22, 2019
TEHRAN – Iranian director Reza Mirkarimi has said that his country can learn from China about making sci-fi and action movies.
He made the remarks during a question and answer panel held after a screening of his film “Castle of Dreams” at the Tsinghua University in Beijing on November 7, Global Times, an English-language Chinese daily, announced last Tuesday.
The film was also screened at the Beijing Film Academy at the same time.
“These genres in Iran are not mainstream. We don’t have enough capacity to achieve what we want,” Mirkarimi said.
“China and Iran are both in the East of the world. We have these common Eastern feelings. There are many Chinese film experts that I’d like to work with, as I’ve seen their works on the screens at international film festivals,” Mirkarimi added.
“Castle of Dreams” is about two young children, whose mother has just died and their father, Jalal, after long years of absence, returns to sort things out, but he does not want to take the children with him.
The film won three main honors at the 22nd Shanghai International Film Festival, including the Golden Goblet Award for the best film.
The film also brought Mirkarimi the best director award, and the film’s star, Hamed Behdad shared the award for best actor with Chang Feng, the Chinese actor of “The Return” by Qin Hailu.
Mirkarimi is currently considering shooting a family drama set in a small city in China and making an animated TV series for children, possibly about the Silk Road and cultural exchange with China.
Quote:Rare-Earth Materials May Start Coming From Japanese Seafloor
Aug 08, 2019 at 11:45am
When oil started to be more and more difficult to obtain – and prices rised – it started to be extracted from the seafloor. Sometimes really deep in the ocean, at depths that can reach 28,000 ft underwater. What if we told you rare-earth materials may one day also come from “under the sea”, as Sebastian would say? Well, that’s the intention.
A group of scientists from the Waseda University made research in an area of more than 617,700 acres (2,500 km²) of the Japanese seabed at depths of 19,000 ft and discovered there very big sources of rare-earth materials.
To be more precise, and taking the current global demand into consideration, it could supply “supply Y (yttrium), Eu (europium), Tb (terbium), and Dy (dysprosium) for 780, 620, 420, and 730 years, respectively,” states the study published at Nature.
The important part is that the area contains “16 million tons of rare-earth oxides”. Once the material is extracted from the bottom of the sea, the researchers propose “hydrocyclone separators” to process the minerals.
