Fluxgate in the Space industry context refers to a type of magnetometer used primarily to measure the intensity and orientation of magnetic fields. Fluxgate magnetometers are commonly employed in satellite Technology and space missions to study Earth's magnetic field and the magnetic fields of other planets and Celestial bodies.

A flyby is a type of mission where a spacecraft flies by a celestial body, such as a planet, moon, or comet, at a relatively close distance without going into orbit around it.

In the aerospace context, Flyer refers to a machine or vehicle that is capable of flying or being flown, such as an aircraft, a spacecraft, or a drone.

Deutsch: Brennweite / Español: Distancia focal / Português: Distância focal / Français: Distance focale / Italiano: Distanza focale

The term focal length is a fundamental optical parameter in the space industry, defining the distance between the optical center of a lens or mirror and its focal point. It determines the magnification, field of view, and resolution of imaging systems used in satellites, telescopes, and remote sensing instruments. In space applications, precise control of focal length is critical for achieving high-performance observations of celestial bodies, Earth's surface, and deep-space phenomena.

Deutsch: Fokus / Español: Enfoque / Português: Foco / Français: Focalisation / Italiano: Focalizzazione /

In the aerospace context, focus refers to the specific area of research, development, or production that a company or organization is emphasizing or prioritizing. This can refer to a particular technology, capability, or market segment.

Deutsch: Filmmaterial / Español: metraje / Português: filmagem / Français: séquences vidéo / Italiano: filmato

Footage in the Space industry context refers to video recordings and visual documentation captured during space missions, training sessions, simulations, and other space-related activities. This footage is crucial for scientific analysis, public engagement, educational purposes, and historical documentation.

Force refers to a measure of the strength or intensity of an interaction between two or more objects. Forces can be caused by a variety of factors, such as gravity, electromagnetism, and friction.

Deutsch: Prognose / Español: Pronóstico / Português: Previsão / Français: Prévision / Italiano: Previsione

Forecasting in the context of the Space industry is the process of predicting future trends, events, and needs within the space sector. These predictions include estimates related to technological advancements, Mission Success rates, budget requirements, market demand for satellite services, and the impact of new regulations on Space Exploration and commercialization. Forecasting enables agencies and companies to make strategic decisions, manage risks, and allocate resources effectively.

Deutsch: Gründer / Español: fundador / Português: fundador / Français: fondateur / Italiano: fondatore

A founder in the Space industry context refers to an individual or a group of individuals who establish and develop a company, organization, or initiative focused on space exploration, technology, or services. Founders are often visionaries who drive innovation, secure funding, and lead their organizations to achieve significant advancements in the space sector.

A field-programmable gate array (FPGA) is an integrated circuit, which can be changed, optimized or configured later (after manufacturing in the field) by a customer or a designer.

Deutsch: Framework / Español: Marco de trabajo / Português: Framework / Français: Cadre de travail / Italiano: Framework

A framework in the space industry refers to a structured set of tools, protocols, and methodologies designed to standardize and streamline the development, operation, and management of space missions, systems, or technologies. These frameworks ensure interoperability, reliability, and compliance with international standards while addressing the unique challenges of space environments, such as extreme conditions, long-duration missions, and complex multi-stakeholder collaborations. They serve as foundational architectures that guide engineers, scientists, and organizations in achieving mission objectives efficiently and safely.

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: Frachter / Español: Buque de carga / Português: Navio de carga / Français: Cargo / Italiano: Nave da carico

A freighter in the space industry refers to a specialized spacecraft designed for the transportation of cargo, equipment, and supplies to various destinations in space. These vessels play a crucial role in supporting space missions by ensuring the timely and efficient delivery of essential resources. Freighters are integral to the infrastructure of space exploration and commercial space activities.

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.
