I. What is Specific Orbital Energy? Specific orbital energy is a term used in the field of aerospace engineering to describe the energy associated with an object in orbit around a celestial body, such as a planet or a star. It is a measure of the total energy of the object in its orbit, taking … Read more
What is Medium Earth Orbit (MEO)? Medium Earth Orbit (MEO) is a type of orbit that lies between Low Earth Orbit (LEO) and Geostationary Orbit (GEO). Satellites in MEO typically orbit the Earth at altitudes ranging from 2,000 to 35,786 kilometers. This orbit is commonly used for satellite communication and navigation systems due to its … Read more
I. What is a Heavy-lift Launch Vehicle? A heavy-lift launch vehicle is a type of rocket that is designed to carry large payloads into space. These rockets are capable of lifting much heavier loads than traditional rockets, making them essential for launching satellites, space stations, and other large spacecraft into orbit. Heavy-lift launch vehicles are … Read more
I. What is Pogo Oscillation? Pogo oscillation, also known as pogo effect or pogo instability, is a phenomenon that occurs in rocketry and propulsion systems. It is characterized by repetitive oscillations in the propulsion system, which can lead to structural damage, performance degradation, and even mission failure. Pogo oscillation is a serious concern for engineers … Read more
What is a Reusable Launch Vehicle (RLV)? A Reusable Launch Vehicle (RLV) is a type of spacecraft that is designed to be launched into space multiple times without being completely destroyed or discarded after each mission. Traditional rockets are typically used only once and are either destroyed or left to burn up in the atmosphere … Read more
I. What is a Gyroscope? A gyroscope is a device used to measure or maintain orientation and angular velocity. It consists of a spinning wheel or rotor mounted on a set of gimbals, which allows it to freely rotate in any direction. Gyroscopes are commonly used in navigation systems, robotics, and aerospace applications to provide … Read more
I. What is a Reaction Control System (RCS)? A Reaction Control System (RCS) is a system used in spacecraft and rockets to control their orientation and position in space. It consists of thrusters that are strategically placed on the spacecraft to provide small amounts of thrust in different directions. This allows the spacecraft to make … Read more
I. What is a Bi-elliptic Transfer? In the realm of astrodynamics and rocketry, a Bi-elliptic Transfer is a maneuver used to transfer a spacecraft from one circular orbit to another, using two elliptical orbits as intermediaries. This type of transfer is particularly useful when the desired change in orbit is significant and when fuel efficiency … Read more
I. What is Geostationary Orbit? Geostationary orbit is a specific type of orbit around Earth where a satellite orbits at the same rate as the Earth’s rotation, allowing it to remain stationary relative to a fixed point on the Earth’s surface. This means that from the perspective of an observer on the ground, the satellite … Read more
I. What is a Pulsed Plasma Thruster? A Pulsed Plasma Thruster (PPT) is a type of electric propulsion system that generates thrust by accelerating a high-temperature plasma to produce thrust. This technology is commonly used in spacecraft propulsion systems due to its efficiency and simplicity. II. How does a Pulsed Plasma Thruster work? A Pulsed … Read more
