I. What is Gravitational Capture? Gravitational capture is a phenomenon in celestial mechanics where an object, such as a spacecraft or satellite, is captured by the gravitational field of a larger celestial body, such as a planet or moon. This process occurs when the object enters the gravitational sphere of influence of the larger body … Read more
I. What is a Launch Escape System? A Launch Escape System (LES) is a crucial safety feature designed to protect astronauts in the event of an emergency during the launch phase of a spacecraft. It is a system that can quickly propel the crew capsule away from the rocket in case of a malfunction or … Read more
I. What is a Pressure-fed Engine? A pressure-fed engine is a type of propulsion system commonly used in rockets and spacecraft. Unlike traditional engines that rely on pumps to deliver fuel and oxidizer to the combustion chamber, a pressure-fed engine uses the pressure of the propellant tanks to push the fuel and oxidizer into the … Read more
I. What is a Hybrid Propellant Engine? A hybrid propellant engine is a type of rocket engine that uses a combination of solid and liquid propellants to generate thrust. In a hybrid propellant engine, a solid fuel grain is combined with a liquid oxidizer to create combustion and produce thrust. This type of engine offers … Read more
I. What is Variable Specific Impulse Magnetoplasma Rocket (VASIMR)? The Variable Specific Impulse Magnetoplasma Rocket, or VASIMR, is a type of electric propulsion system that uses radio waves to ionize and heat a propellant, typically hydrogen or argon, into a plasma state. This plasma is then accelerated through a magnetic nozzle to generate thrust. VASIMR … Read more
I. What is Trans-lunar Injection (TLI)? Trans-lunar Injection (TLI) is a crucial maneuver used in space exploration missions to propel a spacecraft from Earth’s orbit towards the Moon. This maneuver is essential for sending spacecraft beyond Earth’s orbit and into the vast expanse of space towards the Moon. TLI is a complex process that requires … Read more
I. What is Trans-Martian Injection (TMI)? Trans-Martian Injection (TMI) is a crucial maneuver used in space exploration to send spacecraft from Earth’s orbit to Mars. This maneuver involves propelling a spacecraft out of Earth’s orbit and into an orbit that intersects with Mars’ orbit. TMI is essential for missions to Mars as it allows spacecraft … Read more
I. What is Methalox? Methalox is a type of rocket propellant that consists of a mixture of methane and liquid oxygen. The name “Methalox” is derived from the combination of the words “methane” and “lox,” which is a common abbreviation for liquid oxygen. Methane is a hydrocarbon compound that is abundant on Earth and can … Read more
