I would like to write about any scientific topic I like. I love Aeronautics, and my dream is to become an Astronaut. I focus on the Solar System but I am not limited by any interesting topic, which I will find on this journey. Especially, I am a big fan of Mercury, Gemini and Apollo era and the Space Race. I would like to get in and bring new approach on the history, since I was solar wind scientist. Suggestions are highly welcome! Enjoy!!

Rocket engine propellants

A rocket engine uses stored rocket propellants as the reaction mass. Reaction mass forms a high speed propulsive jet of fluid, usually high temperature gas. Rocket engines are type of engines using reaction, producing thrust by ejecting mass rearward, according to the Newton's third law of action and reaction. Most rocket engines use the combustion of reactive chemicals to supply the necessary energy, but non-combusting forms such as cold gas thrusters and nuclear thermal rockets also exist. RD-180 test firing at Marshall Space Flight Center, source wiki Rocket engines produce thrust by the ejection of an exhaust fluid that has been accelerated to high speed through a propelling nozzle. The fluid is usually a gas created by high pressure combustion of solid or liquid propellants, consisting of fuel and oxidizer, inside a combustion chamber. As the gases expand through the nozzle, they are accelerated to very high speed, and the reaction to this pushes the engine in the opposite dir

Space Shuttle orbiter

The Space Shuttle orbiter is the spaceplane component of the Space Shuttle, a partially reusable orbital spacecraft system that was part of the discontinued Space Shuttle program. Operated from 1977 to 2011 by NASA. Orbiter is the part of the Space Shuttle system that looks like an airplane. The size is very similar to that of standard medium size commercial passenger jet such as Boeing 747. Figure 1: Discovery approaches the International Space Station (ISS) on STS-121; source: wiki Six orbiters were built for flight: Enterprise, Columbia, Challenger, Discovery, Atlantis, and Endeavour. Space Shuttle Enterprise (Orbiter Vehicle Designation: OV-101) was the first orbiter of the Space Shuttle system. Rolled out on September 17, 1976, it was built for NASA as part of the Space Shuttle program to perform atmospheric test flights after being launched from a modified Boeing 747. It was constructed without engines or a functional heat shield. As a result, it was not capable of spaceflight

SpaceX Falcon9

SpaceX Falcon 9 Falcon 9 is a partially reusable, human-rated, two-stage-to-orbit, medium-lift launch vehicle designed and manufactured in the United States by SpaceX. That says wikipedia. Let's go deeper into it. Falcon 9 is a reusable, two-stage rocket designed and manufactured by SpaceX to transport of people and payloads into Earth orbit and hopefully beyond. Falcon 9 rocket is the first orbital class of reusable rocket that flies to ISS and other private programs. It helps to reduce to price and cost of the flight of the rocket, as it is used again for the next plan helping the space game open to broader context. The first Falcon 9 launch was on 4 June 2010, and the first commercial resupply mission to the International Space Station (ISS) was launched on 8 October 2012. In 2020, it became the first commercial rocket to launch humans to orbit to ISS. The height of the Falcon 9 is 70 m and diameter is 3.7 m. Mass is 549,054 kg. The rocket has two stages. The first (booster)
