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!!

Delta (rocket family)

Note before you even start to read. I have started with this article in 2018. I have tried to go through all rocket types and families, which were launched or used or planned, but I needed to take a break. So, I had to change several things in the following article. I hope it will still stay consistent. Delta rocket family is American expendable launch system since 1960 with 95 per cent of successful launches. Currently Delta IV Heavy rocket remains in use as by November 2020. The original Delta rocket was developed and built by Douglas Aircraft Company and it has origin in Thor IRBM (deployed in the UK between the years 1959 and 1963). IRBM is abbreviation which stands for Intermediate Range Ballistic Missile. After Sputnik 1 was launched in October, 4, 1957, Thor was developed into a space program direction and become a basis of Delta rocket. Thor was developed into Delta, so basically Thor is the first rocket in Delta rocket family. The original Delta rockets used Thor as th

Space Rocket Engine

Space rocket engine What is the difference between the jet engine and space rocket engine? They both produce thrust and, as explained by Newton’s Third Law of Motion, eject exhaust gases in an equal and opposite direction. The difference between them is that jet engines get the oxygen to burn fuel directly from the atmosphere and space rockets carry their own oxygen onboard, which allows them to operate in space. You can see main characters on following two Figures 1 and 2. Figure 1. Turbojet engine; source: Rolls-Royce plc (1996). The Jet Engine. Fifth Edition. Derby, England. Figure 2. A liquid space rocket engine; source: Rolls-Royce plc (1996). The Jet Engine. Fifth Edition. Derby, England. There are four major components to space rocket: (1) the structural system, or frame, (2) the payload system, (3) the guidance system, and (4) the propulsion system. The propulsion system includes the tanks pumps, propellants, power head and rocket nozzle. The function of the propulsion syste

Where is the edge of space?

Where is the edge of space and what is the Karman line? credit: National Geographic Definition where the space starts is not completely clear. Satellite in space collides with billions of air molecules from the atmosphere. The frequency and intensity of these collisions increases with increasing velocity. At orbital velocity, the energy from those collisions with air molecules produces heat that would melt even metal. It is known as the friction heating effect. All orbiting satellites must operate in space in order to avoid the frictional heating effect. It is difficult to estimate. Traces of the gases which we are breathing extends beyond 161 km above the Earth's surface. Above this altitude it is safe for satellite to move at orbital speed without the danger of incineration from the frictional heating. Many other definitions exist where the space really begins. Generally, it is told that space starts at the point where orbital dynamic forces become more important than aerodyn
