These criteria are put in place to ensure the safety and success of the mission. They cover a wide range of factors, including weather conditions, technical readiness of the … Read more
I. What is Engine Cutoff (ECO)? Engine Cutoff (ECO) is a crucial phase during a rocket launch where the engines of the rocket are shut down. This marks the end of the powered flight phase and the beginning of the coasting phase of the rocket’s journey. ECO is a carefully planned and executed event that … Read more
I. What is a Reaction Wheel? A reaction wheel is a type of flywheel used in spacecraft to control the orientation of the vehicle without the need for thrusters. It consists of a spinning wheel mounted on a spacecraft that can be rotated to produce torque in the opposite direction, allowing the spacecraft to change … Read more
I. What is Ascent Phase in Rocketry? The ascent phase in rocketry refers to the stage of a rocket launch where the vehicle is propelled upwards into space. It is a critical phase of the launch process as it involves overcoming Earth’s gravitational pull and reaching the desired altitude for the mission. During the ascent … Read more
I. What is a Hohmann Transfer Orbit? A Hohmann Transfer Orbit is a type of orbital maneuver used in spaceflight to transfer a spacecraft from one circular orbit to another. It was first proposed by German engineer Walter Hohmann in 1925 and has since become a fundamental concept in the field of astrodynamics. The Hohmann … Read more
I. What is a Launch and Entry Suit? A Launch and Entry Suit, also known as a LES, is a specialized type of spacesuit worn by astronauts during the launch and re-entry phases of a space mission. These suits are designed to protect astronauts from the extreme conditions experienced during these critical phases of space … Read more
