I. What is a Wet Workshop? A wet workshop is a method of spacecraft construction where the vehicle is assembled and outfitted while filled with propellant. This is in contrast to a dry workshop, where the spacecraft is built and then fueled with propellant before launch. The term “wet” refers to the presence of liquid … Read more
What is Lunar Orbit Rendezvous? Lunar Orbit Rendezvous (LOR) is a spaceflight technique used to land astronauts on the moon and return them safely to Earth. It was first proposed by John Houbolt, an engineer at NASA, in the early 1960s as a way to achieve the ambitious goal set by President John F. Kennedy … Read more
I. What is Solar Electric Propulsion (SEP)? Solar Electric Propulsion (SEP) is a type of propulsion system that uses solar energy to generate electricity, which is then used to power electric thrusters. These thrusters use electric fields to accelerate ions or other propellant particles to generate thrust. SEP is a promising technology for spacecraft propulsion … Read more
I. What is Zero-gee Fluid Behavior? Zero-gee fluid behavior refers to the way fluids behave in a microgravity environment, where the effects of gravity are greatly reduced or eliminated. In space, fluids such as water, fuel, and gases behave differently than they do on Earth due to the absence of gravity. This unique behavior has … Read more
I. What is Project Orion? Project Orion was a groundbreaking concept for a spacecraft propulsion system that was first proposed in the late 1950s. The project aimed to use nuclear explosions to propel a spacecraft through space, offering a level of power and efficiency that had never been seen before in rocketry. The idea was … Read more
I. What is a Gimbal? A gimbal is a mechanical device that allows an object to remain level and stable regardless of the motion of its base. It consists of a pivoted support that allows the object to rotate on its axis in any direction. Gimbals are commonly used in a variety of applications, including … Read more
I. What is Azimuth in Launch Trajectory? Azimuth in launch trajectory refers to the horizontal angle at which a rocket is launched from its initial position. It is measured in degrees clockwise from true north. Azimuth plays a crucial role in determining the direction in which the rocket will travel once it is launched. By … Read more
I. What is Specific Energy? Specific energy is a term used in physics and engineering to describe the amount of energy stored in a material per unit mass. It is a crucial parameter in various fields, including rocketry, where the efficient use of energy is essential for achieving high performance. In rocketry, specific energy is … Read more
I. What is an Engine Bell? An engine bell, also known as a rocket nozzle, is a crucial component of a rocket engine that plays a vital role in the propulsion of the rocket. It is the part of the engine that directs and accelerates the flow of exhaust gases produced by the combustion of … Read more
I. What is High Earth Orbit (HEO)? High Earth Orbit (HEO) is a type of orbit around the Earth that is significantly higher than low Earth orbit (LEO) and medium Earth orbit (MEO). Satellites in HEO typically orbit at altitudes ranging from 35,786 kilometers (22,236 miles) to 42,164 kilometers (26,199 miles) above the Earth’s surface. … Read more
