[13] [14] [15] On June 14, 1949, the US launched the first mammal into space, a rhesus macaque monkey named Albert II, on a sub-orbital flight, though Albert II died when the parachute failed. [16] On July 22, 1951, the Soviets launched the Soviet space dogs, Dezik and Tsygan, who were the first dogs in space and the first to safely return. [17]

Internal combustion engines date back to between the 10th and 13th centuries, when the first rocket engines were invented in China. Following the first commercial steam engine (a type of external combustion engine) by Thomas Savery in 1698, various efforts were made during the 18th century to develop equivalent internal combustion engines.
The RS-25 engine consists of pumps, valves, and other components working in concert to produce thrust. Fuel (liquid hydrogen) and oxidizer (liquid oxygen) from the Space Shuttle's external tank entered the orbiter at the umbilical disconnect valves and from there flowed through the orbiter's main propulsion system (MPS) feed lines; whereas in the Space Launch System (SLS), fuel and oxidizer ...
In 1897, he built the first Russian wind tunnel with an open test section and developed a method of experimentation using it. In 1900, with a grant from the Academy of Sciences, he made a survey using models of the simplest shapes and determined the drag coefficients of the sphere, flat plates, cylinders, cones, and other bodies.
MW 18014 was a German A-4 test rocket [nb 1] launched on 20 June 1944, [1] [2] [3] at the Peenemünde Army Research Center in Peenemünde.It was the first human-made object to reach outer space, attaining an apogee of 176 kilometres (109 mi), well above the Kármán line that was established later as the lowest altitude of space.

Few would recognize it at the time, but this little engine was a major breakthrough. These experiments suggested that rockets could be made powerful enough to escape Earth and travel into space. This engine and subsequent experiments sponsored by the Smithsonian Institution were the beginning of modern rocketry and, ultimately, space ...
At T+4 seconds, when the Space Shuttle reached an altitude of 22 meters (73 ft), the RS-25 engines were throttled up to 104.5%. At approximately T+7 seconds, the Space Shuttle rolled to a heads-down orientation at an altitude of 110 meters (350 ft), which reduced aerodynamic stress and provided an improved communication and navigation orientation.
