It is derived from the Falcon 9 vehicle and consists of a strengthened Falcon 9 first stage as a central core with two additional first stages as strap-on boosters.

Its official program name was Space Transportation System STS , taken from a plan for a system of reusable spacecraft of which it was the only item funded for development. It is built by Khrunichev, and launched from sites 81 and at the Baikonur Cosmodrome in Kazakhstan. The first Proton-M launch occurred on 7 April Variants include the inital v1.
Falcon 9 is powered by rocket engines utilizing liquid oxygen LOX and rocket-grade kerosene RP-1 propellants. Air Force. Subscribe to our channel for more videos like this! Found the story interesting?

Interest in rockets goes back to ancient times when the Chinese used rockets that burned solid fuel for entertainment and for warfare. The British and other Europeans used rockets in the 19th century for military purposes.
They were also used for peaceful purposes such as for launching life-saving equipment from shore into the water to rescue sailors. A major problem was that these early rockets used solid propellants, which lacked much power, and they were unguided, meaning that they rarely hit their target.

In the 20th century engineers began developing liquid-fueled rockets and guidance systems. In World War II the Germans succeeded in inventing rockets that could be guided to more distant targets with rough accuracy the ability to hit city-sized targets or more miles away.
When the war ended, hundreds of German rocket experts came to the United States and were instrumental in developing the American space program. The Soviet Union also used German rocket experts, but did not incorporate these people into their own space program. After obtaining their knowledge, the Soviets confined them to Germany and allowed them to conduct only non-rocket research. All three worked in relative isolation from each other during the early part of the 20th century.
Oberth and Tsiolkovsky were largely theorists, writing about orbits and the possibility of space travel.
Tsiolkovsky wrote about space stations. Both men's writings influenced many people, particularly in their own countries, to believe that spaceflight was possible. Unlike Oberth and Tsiolkovsky, Robert Goddard was more of a hands-on engineer than a theoretician. He was the first person to research liquid-fueled rockets and developed several gasoline-fueled experimental rockets that he fired at a test range near Roswell, New Mexico. But because he was reclusive he did not pass many of his accomplishments on to others and did not train younger engineers how to build rockets; this may have slowed the progress of rocketry in the United States.
Spacecraft and spaceflight missions fall into three main categories: human spaceflight, Earth-focused spaceflight, and astronomical and planetary spaceflight.
The first vehicle launched into space was Sputnik, which the Soviet Union shot into orbit in October Sputnik was the opening round in what became known as the "Space Race," where the United States and the Soviet Union competed to achieve various firsts in space in order to demonstrate the superiority of their political and economic systems and their way of life. The Space Race continued for the next three decades, but lost considerable momentum by the s and s.
Spaceflight is flight that occurs beyond the Earth's atmosphere using vehicles called spacecraft. Spacecraft can orbit around another body-these are called satellites-and can also travel between and beyond planets into the distances of outer space. In common usage, satellites refer to spacecraft that do not have a crew on board. These are often called unmanned or robotic spacecraft, and robotic spacecraft that travel to other planets are often called space probes. In the Soviets sent the first human into space-Yuri Gagarin. Human spaceflight quickly became the main aspect of competition in the Space Race, and the most expensive.
Although the Soviets undoubtedly won the opening rounds of the Space Race, the United States caught up quickly and by the mids had passed them in terms of total hours of humans in space and other accomplishments.
The ultimate achievement was the landing of Neil Armstrong and Edwin "Buzz" Aldrin on the moon in It was this Cold War competition, rather than a strong interest in science or the mysteries of space, that served as the incentive for both countries to invest the large amounts of resources that they have in their respective space programs, and especially in their human spaceflight programs. Once the Cold War ended by with the collapse of the Soviet Union, money for spaceflight decreased and in many ways, the continuing space programs of the United States and Russia are a result of political and bureaucratic inertia, with tens of thousands of jobs depending upon continuing spaceflight.
The most ambitious human spaceflight program, from both a technological and a financial standpoint, is the International Space Station, or ISS, now being developed by a consortium consisting of Russia, the United States, Europe, Japan, and others. But it has proven to be an astoundingly expensive project and these costs have dramatically reduced its scientific potential.
Because a significant amount of human activity in space involves fixing things that break, the ISS cannot produce any useful scientific data until it has a crew size greater than three, which can only be achieved at considerable new expense. As a result, even today, after the end of the Space Race, most human spaceflight remains more symbolic than beneficial or practical. Robotic, Earth-focused spaceflight offers the most direct benefits to those on Earth.
Communications satellites, meteorological satellites and remote-sensing satellites fall into these categories.

Communications satellites enable audio, video and data signals to be transmitted around the globe quickly and efficiently, shrinking the size of the Earth as people around the world can communicate with each other almost instantaneously. Meteorological satellites enable scientists to "see" the Earth's atmosphere.
Instruments on board meteorological and other atmospheric research satellites measure and sample the atmosphere from great distance, identifying areas that may lead to severe storms. These satellites allow meteorologists and researchers to forecast major weather events like hurricanes and track their development and movement, and warn people to get out of the way.
They have saved countless lives. Atmospheric observation satellites are also used to monitor ocean currents and temperature and to analyze trends such as global warming, ozone destruction, and pollutants in the atmosphere. They have played a major role in the debate over human impact on the environment. Remote-sensing satellites view the Earth's surface. They are used for agricultural and land-use monitoring.
