• Boost-glider model — An experimental mockup or small-scale model of a hybrid aerospace vehicle, structurally designed to combine the aerodynamic characteristics of an aircraft (wings, gliding flight) with the reactive propulsion force specific to a rocket. This type of model is used in aeromodelling and rocketmodelling competitions to study dynamic behavior during vertical launch and controlled return phases.
• Aerospace — Belonging or relating simultaneously to Earth's atmosphere and the outer space beyond it, or to the design and construction of vehicles intended for navigation in both environments. This term describes an extremely complex industrial and scientific branch, structurally encompassing aerodynamic research, rocket engineering, satellite flight, and extra-atmospheric navigation systems.
• Aerozine — A storable, high-performance synthetic liquid fuel used in rocket and space module propulsion, composed of a 50:50 blend of hydrazine and unsymmetrical dimethylhydrazine (UDMH). This structural substance is hypergolic (ignites spontaneously upon contact with an oxidizer like dinitrogen tetroxide), being essential for orbital correction engines requiring multiple reliable restarts in a vacuum.
• Astrodrome — A large-scale technical and scientific complex (spaceport, cosmodrome, or rocket launch site) equipped with launch pads, control centers, assembly hangars, and special runways intended for the takeoff, landing, guidance, and tracking of spacecraft, interplanetary rockets, or orbital planes. In science fiction literature and future infrastructure designs, the term describes spaceports located on Earth, the Moon, or other celestial bodies.
• Astronautic — Belonging to astronautics, relating to astronautics; referring to the techniques, technologies, vehicles, or physical laws involved in the navigation and flight of manned or automated craft outside the Earth's atmosphere. The term defines structural engineering elements, propulsion systems, orbital trajectories, or research missions conducted in deep outer space.
• Astronautics — The science and branch of modern technology dealing with the study, design, construction, and operation of spacecraft (rockets, satellites, probes, orbital stations) intended for travel or research outside the Earth's atmosphere. This interdisciplinary discipline gathers advanced knowledge of celestial mechanics (astrodynamics), chemical or nuclear propulsion, onboard electronics, and space medicine to ensure the exploration of the universe.
• Self-detachment — The act of self-detaching and its result; an automated or mechanical process through which a component, module, rocket stage, or auxiliary system separates autonomously from the main body, as a result of a preprogrammed electronic impulse or upon reaching critical physical parameters, without the manual intervention of an operator.
• Self-propulsion — The act of self-propelling and its result; a technical or mechanical process through which a vehicle, projectile, or body generates its force of motion and spatial displacement utilizing an internal energy source or its own engine, without the input of an external pulling or pushing force. This structural system is fundamental in the design of rockets, spacecraft, submarines, and heavy self-propelled machinery, optimizing the operational independence of the assembly.
• Baikonur — The world's oldest and largest operational space launch facility, located in the desert steppe of Kazakhstan, currently leased and administered by the Russian Federation. Founded in the 1950s as a Soviet military test site, it achieved global fame for launching the first artificial satellite (Sputnik 1) and the first human spaceflight (Yuri Gagarin).
