Video is an electronic medium for the recording, copying, playback, broadcasting, and display of moving visual media.

Deutsch: Videografie / Español: Videografía / Português: Videografia / Français: Vidéographie / Italiano: Videografia

Videography in the space industry refers to the process of capturing, recording, and analyzing video footage of space missions, spacecraft operations, and extraterrestrial environments. This practice is essential for documenting missions, conducting scientific research, and providing educational and public outreach.

Vikings is the modern name given to seafaring people originally from Scandinavia (present-day Denmark, Norway and Sweden), who from the late 8th to the late 11th centuries raided, pirated, traded and settled throughout parts of Europe.

Deutsch: Viskosität / Español: viscosidad / Português: viscosidade / Français: viscosité / Italian: viscosità

Viscosity in the space industry context refers to the measure of a fluid's resistance to flow, which is a crucial property when designing and operating spacecraft systems that involve liquids, such as fuel, lubricants, and life support systems. In the microgravity environment of space, viscosity plays a vital role in ensuring that these fluids behave predictably and function effectively.

Deutsch: Sichtbarkeit / Español: Visibilidad / Português: Visibilidade / Français: Visibilité / Italiano: Visibilità /

Visibility in the space industry context refers to the ability to track and communicate with spacecraft, satellites, and other space assets. It encompasses the ability to monitor a space object's position, trajectory, and status, as well as to establish reliable communication links with it. Visibility is a critical aspect of space operations, as it enables operators and mission controllers on Earth to maintain control, monitor health, and receive data from spacecraft in orbit or on deep space missions. In this article, we will explore the concept of visibility in the space industry, discuss its significance, and provide examples of its application in various space missions.

Visual flight rules (VFR) is a regulatory term describing flights that are conducted only in conditions where the pilot can see the ground, or in some instances is flying in the free space above a cloud. Compare to instrument flight rules.

Deutsch: Visualisierung / Español: Visualización / Português: Visualização / Français: Visualisation / Italiano: Visualizzazione

Visualization in the space industry refers to the use of graphical or visual representations to model, simulate, or interpret space missions, data, spacecraft systems, and celestial phenomena. It plays a crucial role in mission planning, operations, data analysis, and communication, enabling engineers, scientists, and decision-makers to better understand complex data, processes, and systems involved in space exploration and satellite operations.

Deutsch: Flüchtige Entwicklung / Español: Evolución de Volátiles / Português: Evolução de Voláteis / Français: Évolution des Volatils / Italiano: Evoluzione dei Volatili

Volatile Evolution in the space industry context refers to the study and analysis of the changes and behaviour of volatile substances—such as water, carbon dioxide, methane, and other gases—on celestial bodies over time. This includes understanding how these volatiles are released, trapped, or altered due to geological, atmospheric, or solar interactions. In planetary science and exploration, volatile evolution is crucial for uncovering the history of planetary atmospheres, assessing habitability, and planning resource utilisation for future space missions.

Deutsch: Volatilität / Español: Volatilidad / Português: Volatilidade / Français: Volatilité / Italiano: Volatilità

Volatility in the space industry refers to the propensity for rapid or significant fluctuations in key variables, such as market conditions, technological developments, geopolitical factors, or operational environments. It is often used to describe the unpredictability and dynamic nature of the space sector, which can affect investment, mission planning, and industry stability.

Deutsch: Vulkanismus / Español: Vulcanismo / Português: Vulcanismo / Français: Volcanisme / Italiano: Vulcanismo

Volcanism in the space industry context refers to the study and observation of volcanic activity on planets, moons, and other celestial bodies. This field is essential for understanding the geological history, surface composition, and internal dynamics of these bodies, which in turn provides insights into their formation, evolution, and potential habitability.

Deutsch: Vulkan / Español: Volcán / Português: Vulcão / Français: Volcan / Italian: Vulcano

Volcano in the space industry refers to a large, often high-risk rocket or launch vehicle with an exceptionally powerful thrust capability. These rockets are designed to carry heavy payloads into space, often beyond Earth's orbit, and are a key component in ambitious space missions, including those aimed at exploring deep space or sending large satellites and modules into orbit. The term can also refer to the challenges and risks associated with launching such massive and powerful rockets.

Deutsch: Spannung / Español: Voltaje / Português: Voltagem / Français: Tension / Italian: Tensione

Voltage in the space industry refers to the electrical potential difference that drives the flow of current in spacecraft systems and other space-related technologies. It is a critical parameter that influences the performance, reliability, and safety of electrical and electronic systems used in space missions.

Deutsch: Wostok / Español: Vostok / Português: Vostok / Français: Vostok / Italiano: Vostok

Vostok refers to the series of Soviet space missions and the associated spacecraft that achieved significant milestones in human spaceflight during the early 1960s. These missions are best known for including the first human spaceflight by Yuri Gagarin on April 12, 1961. The Vostok program marked a pivotal moment in the space race and laid the groundwork for future manned space missions.

In the aerospace context, Voyager refers to a series of NASA's space probes that were launched in the 1970s to study the outer Solar System. The Voyager program consisted of two spacecraft, Voyager 1 and Voyager 2. Both were launched in 1977, and were designed for a mission to study the gas giant planets Jupiter and Saturn, and their moons.

Deutsch: Senkrechtstart und -landung / Español: Despegue y aterrizaje vertical / Português: Decolagem e Aterrissagem Vertical / Français: Décollage et atterrissage verticaux / Italiano: Decollo e atterraggio verticale

VTOL in the space industry context stands for Vertical Take-Off and Landing. It refers to the capability of spacecraft or launch vehicles to take off and land vertically, as opposed to traditional horizontal runway landings or parachute-assisted splashdowns. This technology is particularly relevant for reusable rocket stages, which land vertically after separating from the main vehicle to be refurbished and flown again, and for spacecraft designed for missions to other planets or moons where runways may not be available.
