Knowra Astronautics Astronautics Astronautics is the science and engineering of designing, building, and operating vehicles and systems for travel and activity in space. It combines spacecraft engineering, orbital mechanics, propulsion, and mission operations.
Orbital mechanics : The study of how gravity governs the motion of objects in orbit. It predicts spacecraft trajectories and determines how missions reach, change, and leave orbit.
Newton's laws of motion : Three physical laws relating an object's motion to forces acting on it. They underpin calculations of launch, maneuvering, and spacecraft motion.
Satellite : An object placed in orbit around a planet or other celestial body. Satellites are the most widespread spacecraft, serving communications, navigation, observation, and research.
Aeronautics : The science and engineering of flight through Earth's atmosphere. It shares vehicle design concerns with astronautics but operates in an atmosphere rather than space.
Rocket propulsion : The production of thrust by expelling propellant, enabling motion in space without surrounding air. Rockets provide the impulse needed to launch spacecraft and change their trajectories.
Gravitation : The interaction by which masses attract one another and shape the motion of celestial bodies. Gravity determines orbital paths and the energy required to travel between worlds.
Human spaceflight : Space missions that carry people beyond Earth's atmosphere. Crewed missions add life support, human factors, and return safety to spacecraft design.
Astrodynamics : The application of celestial mechanics to the motion and trajectories of spacecraft. It is a focused mathematical discipline within astronautics, centered on spacecraft motion.
Spacecraft attitude control : The sensing and control of a spacecraft’s orientation in space. Pointing instruments, antennas, and engines in the right direction depends on attitude control.
Systems engineering : An approach to designing and managing complex systems by coordinating requirements, components, and interactions. Space missions integrate interdependent hardware, software, operations, and safety requirements.
