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!!

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

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

Solid-propellant rocket

Solid-propellant rocket A solid-propellant rocket or solid rocket is a rocket with a rocket engine that uses solid propellants (fuel/oxidizer). The earliest rockets were solid-fuel rockets powered by gunpowder. The origin of gunpowder rockets can be attributed to ancient Chinese. All rockets used some type of form of solid or powdered propellant up until the 20th century, after which liquid-propellant rockets offered more efficient and controllable alternatives. Solid rockets are still used today in military worldwide, model rockets, solid rocket boosters and on larger applications for their simplicity and reliability. A simplified diagram of a solid-fuel rocket. source: https://www.grc.nasa.gov/www/k-12/airplane/srockth.html 1. A solid fuel-oxidizer mixture (propellant) is packed into the rocket, with a cylindrical hole in the middle. 2. An igniter combusts the surface of the propellant. 3. The cylindrical hole in the propellant acts as a combustion chamber. 4. The hot exhaust is chok
