Deutsch: Fraunhofer / Español: Fraunhofer / Português: Fraunhofer / Français: Fraunhofer / Italiano: Fraunhofer

Fraunhofer in the Space industry context refers to the Fraunhofer lines, a set of dark Absorption lines seen in the solar spectrum, which were first observed and studied by the German Physicist Joseph von Fraunhofer in the early 19th century. These lines are crucial for understanding the Composition of the Sun and other stars, and they play a significant role in astronomical spectroscopy.

Deutsch: Französisch-Guayana / Español: Guayana Francesa / Português: Guiana Francesa / Français: Guyane Française / Italiano: Guiana Francese

French Guiana is a French overseas department located on the northeastern coast of South America. It plays a significant role in the Space industry, primarily due to the presence of the Guiana Space Centre (Centre Spatial Guyanais, CSG), one of the world’s most important spaceports.

Deutsch: Frequenz / Español: Frecuencia / Português: Frequência / Français: Fréquence / Italiano: Frequenza /

Frequency typically refers to the number of oscillations or cycles per unit of time of a periodic signal or phenomenon. It is typically measured in Hertz (Hz), which is the number of cycles per second.

Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other.

Fibre-reinforced plastic (FRP; also called fibre-reinforced polymer, or in American English fiber) is a composite material made of a polymer matrix reinforced with fibres.

In the aerospace context, "FSO" can refer to several different things, depending on the context. Here are a few possibilities:

Deutsch: Treibstoff / Español: Combustible / Português: Combustível / Français: Carburant / Italiano: Carburante /

Fuel refers to the substance that is used to power aircraft, spacecraft, and other aerospace vehicles. The most common type of fuel used in aviation is jet fuel, which is a specialized type of petroleum-based fuel that is designed to be used in aircraft engines.

Deutsch: Kraftstoffabsorption / Español: Absorción de combustible / Português: Absorção de combustível / Français: Absorption de carburant / Italiano: Assorbimento del carburante

Fuel absorption in the Space industry context typically refers to the process or technology used to manage fuel within Spacecraft, satellites, or rockets in a way that maximizes efficiency and safety. This might involve materials or systems that can absorb fuel and then release it as needed, or methods to minimize the risk of fuel sloshing or vapor formation under zero-Gravity conditions, which can affect vehicle control and engine Performance.

Deutsch: Kraftstoffeffizienz / Español: Eficiencia de combustible / Português: Eficiência de combustível / Français: Efficacité énergétique / Italiano: Efficienza del carburante

Fuel Efficiency in the Space industry refers to the effectiveness with which spacecraft use their fuel to achieve their missions. This includes maximizing the distance traveled or the amount of work done per unit of fuel, optimizing propulsion systems, and minimizing fuel consumption to extend mission duration and reduce costs.

Deutsch: Kraftstoffeffizient / Español: Eficiencia de combustible / Português: Eficiência de combustível / Français: Efficacité énergétique / Italiano: Efficienza del carburante

Fuel-efficient in the Space industry context refers to the design and operation of spacecraft, rockets, and propulsion systems that make optimal use of fuel to achieve their mission objectives, thereby reducing the amount of fuel required for Launch, maneuvering, and sustaining operations in Space. This concept is crucial not only for minimizing operational costs but also for maximizing the Payload capacity and extending the mission duration of spacecraft. Fuel efficiency is achieved through advanced propulsion technologies, careful mission planning, and innovative spacecraft designs that reduce Weight and drag.

Deutsch: Betankung / Español: Combustible / Português: Abastecimento / Français: Ravitaillement / Italiano: Rifornimento

Fueling in the Space industry context refers to the process of loading propellant into rockets, spacecraft, or satellites to enable thrust and manoeuvrability in space. Fueling is a crucial step for space missions, as propellant not only powers the launch vehicle to overcome Earth’s Gravity but also allows spacecraft to perform orbital adjustments, control orientation, and complete specific manoeuvres once in space. The process requires stringent safety protocols, specialised equipment, and, often, controlled environments to handle highly reactive fuels.

Deutsch: Full-Stack / Español: full-stack / Português: full-stack / Français: full-stack / Italiano: full-stack

Full-stack in the Space industry context refers to the comprehensive integration and management of all aspects of space mission development, including hardware, software, systems engineering, and operations. This term is borrowed from software development, where a full-stack developer handles both front-end and back-end development. In the space industry, a full-stack approach ensures that all components of a space mission or system work seamlessly together, from initial Design through to mission execution and data analysis.

Deutsch: Funktion / Español: Función / Português: Função / Français: Fonction / Italiano: Funzione

Function in the Space industry refers to the specific role or purpose that a spacecraft, satellite, or any space-related system is designed to perform. The function of a space system dictates its design, components, and operational procedures, guiding everything from the mission objectives to the technological specifications and Support infrastructure.

Deutsch: Finanzierung und Ressourcen / Español: Financiación y recursos / Português: Financiamento e recursos / Français: Financement et ressources / Italiano: Finanziamento e risorse

Funding and resources in the Space industry refers to the financial support, investments, and physical or human resources necessary for the Development, operation, and maintenance of space missions, projects, and Infrastructure. This encompasses both public and private funding, as well as various types of resources like technology, materials, and skilled personnel required to support space activities.

In the aerospace industry, the fuselage is the main body of an aircraft. It is the structure that houses the crew, passengers, and cargo, and it typically extends from the front of the aircraft (the nose) to the tail. The fuselage is usually the longest and most prominent part of an aircraft, and it often has a tubular or oval shape.
