• To moon-land — To perform a controlled descent and touchdown maneuver of a spacecraft, module, or vehicle onto the surface of the Moon. It represents the lunar equivalent of landing, requiring advanced retrorocket systems and structural guidance sensors to overcome the low gravitational pull of Earth's natural satellite.
• Moon landing — The act of landing on the Moon and its result; the dynamic and controlled process of descending, braking, and setting down a spacecraft or exploration module on the lunar surface. This high-precision technical procedure involves utilizing retrorockets to cancel orbital velocity and stabilize the vehicle under the reduced gravity of Earth's natural satellite.
• 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.
• Spacecraft — A spacecraft, cosmic vessel, or complex flight craft structurally designed and equipped to navigate in extra-atmospheric space, transport human crews or scientific payloads, and perform interplanetary or interstellar exploration missions. A spacecraft integrates advanced propulsion, regenerative life support systems, thermal and radiation shielding, and automated guidance equipment necessary for survival and operation in the vacuum of space.
• 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-destruction — The act of self-destructing and its result; the automatic or voluntarily triggered destruction of a system, vehicle, equipment, or software code, or a pathological behavioral manifestation through which an individual sabotages their own life, health, or emotional balance.
• Aviation — The science and technology of air navigation, design, manufacturing, and operation of aircraft heavier than air; by extension, the totality of aircraft, flight and ground crews, as well as airport and administrative infrastructure belonging to a state, a company, or a military branch. It represents a strategic pillar of global transport and national defense systems.
• Aviation chemistry — A specialized branch of the chemical industry and aeronautical engineering dealing with the research, synthesis, production, and testing of chemical materials used in aviation. This includes high-performance fuels, special lubricants resistant to extreme temperatures and pressures, hydraulic fluids, de-icing agents, composite resins, and protective coatings for aircraft structures.
• Avionics — The ensemble of electrical and electronic systems used aboard aircraft, satellites, and spacecraft to perform flight control, navigation, communications, performance monitoring, and weapon systems management. This complex technical discipline encompasses radars, autopilot systems, flight computers, digital cockpit displays (glass cockpit), and telemetric sensors ensuring operational safety.
