In the aerospace context, SDR stands for Software-Defined Radio. It is a type of radio communication system that uses software to define the functions and capabilities of the radio. This allows the radio to be programmed and configured to operate in different frequency bands, modes, and protocols, making it more flexible and adaptable than traditional radios.

Deutsch: Meeresboden / Español: lecho marino / Português: leito marinho / Français: fond marin / Italiano: fondo marino

The seabed represents a critical yet often overlooked frontier in the space industry, serving as both a testing ground for extraterrestrial exploration technologies and a potential analog for planetary surfaces. Its extreme conditions—high pressure, low temperatures, and absence of sunlight—mirror challenges encountered in deep-space missions, making it indispensable for research and development.

Deutsch: Geheimnis / Español: Secreto / Português: Segredo / Français: Secret / Italiano: Segreto

In the Space industry context, secret refers to classified or restricted information related to space missions, technologies, or activities that are not publicly disclosed for reasons of national security, defense, or proprietary protection. Governments and private space companies often keep certain space-related operations secret to protect sensitive Data, technological advancements, military applications, or competitive advantages.

Deutsch: Sektor / Español: Sector / Português: Setor / Français: Secteur / Italiano: Settore

Sector in the space industry refers to a specific division or category within the broader space domain, encompassing various activities, organisations, and applications. It typically denotes a segment of the industry focused on particular functions such as satellite technology, space exploration, or launch services.

Deutsch: Seismologie / Español: Sismología / Português: Sismologia / Français: Sismologie / Italiano: Sismologia /

Seismology is the study of earthquakes and other seismic activity. In the aerospace context, Seismology can be used to study the internal structure and composition of celestial bodies such as planets and moons, by measuring the seismic waves generated by impacts, volcanic activity, or other geological processes.

A seismometer is an instrument that responds to ground noises and shaking such as caused by quakes, volcanic eruptions, and explosions. They are usually combined with a timing device and a Recording device to form a seismograph.

Deutsch: Halbleiter / Español: Semiconductor / Português: Semicondutor / Français: Semi-conducteur / Italiano: Semiconduttore /

In the aerospace industry, a semiconductor is a material that are used to create electronic devices, such as sensors, processors, and controllers. Semiconductors are essential components of many electronic systems used in aerospace applications, including avionics, communications, and guidance and control systems.

SEMS stands for Spacecraft Electrical, Mechanical, and Software Systems. It refers to the various electrical, mechanical, and software systems that are used to control and operate a spacecraft. These systems can include a wide range of components and subsystems, such as electrical power systems, propulsion systems, guidance and navigation systems, and communication systems.

Deutsch: Sensor / Español: Sensor / Português: Sensor / Français: Capteur / Italiano: Sensore /

In aerospace, a sensor is a device that measures or detects a physical property or characteristic of the environment and converts it into a signal that can be read or interpreted by an observer or a measuring instrument.

English: Settlement / Deutsch: Siedlung / Español: Asentamiento / Português: Assentamento / Français: Colonie / Italiano: Insediamento /

In the context of the Space industry, the term "settlement" refers to the establishment of human habitats, Infrastructure, and communities beyond Earth. It represents a visionary concept that envisions a future where humans not only explore space but also live and work in space environments. This article delves into the notion of settlement in the space industry, providing examples of potential settlement initiatives, outlining associated risks, and discussing historical and legal aspects. Furthermore, we will draw parallels with analogous ideas in terrestrial history to underscore the significance of this ambitious endeavor.

Deutsch: Abschattung / Español: Sombreado / Português: Sombreamento / Français: Ombrage / Italiano: Ombreggiatura

The term Shadowing in the space industry refers to the obstruction of electromagnetic signals or solar radiation due to physical obstructions, such as celestial bodies, spacecraft structures, or other objects. This phenomenon plays a critical role in mission planning, communication systems, and power management for satellites and space probes. Understanding and mitigating its effects is essential for ensuring operational reliability in space missions.

In the Space industry context, "Shelter" refers to structures or habitats designed to protect astronauts from the harsh conditions of space or other Celestial bodies, such as the Moon or Mars. These shelters are engineered to provide a safe living and working environment that shields occupants from extreme temperatures, Radiation, micrometeorite impacts, and the Vacuum of space. The Development of effective shelter solutions is a Critical Component of long-duration space missions, including future plans for lunar bases or Martian colonies.

Shenzhou is a series of spacecraft developed and operated by the China National Space Administration (CNSA) for human spaceflight. The Shenzhou spacecraft are part of China's manned spaceflight program, which began in the 1990s with the goal of developing the capability to send Chinese astronauts (taikonauts) into space.

Shielding in the space industry refers to the protective measures and materials used to safeguard spacecraft, equipment, and astronauts from the harmful effects of space radiation, micrometeoroids, and extreme temperatures. Space presents numerous hazards that can jeopardize the integrity and functionality of space assets, making effective shielding a critical aspect of spacecraft design and mission planning. In this article, we will explore the concept of shielding in the space industry, its importance, and provide several examples of shielding techniques and materials commonly employed.

Deutsch: Stoßdämpfung / Español: Absorción de impactos / Português: Absorção de choques / Français: Absorption des chocs / Italiano: Assorbimento degli urti

Shock absorption in the space industry refers to the process of mitigating the impact of sudden forces or vibrations that spacecraft and satellites experience during launch, re-entry, and operation in space. This critical technology ensures the structural integrity and functionality of space systems by dissipating energy that could otherwise cause damage or failure. Effective shock absorption is essential for protecting sensitive components and ensuring mission success.

Deutsch: Sternschnuppe / Español: Estrella fugaz / Português: Estrela cadente / Français: Étoile filante / Italiano: Stella cadente

A shooting Star is not actually a star, but rather a small piece of rock or Dust called a meteoroid that burns up as it enters the Earth's Atmosphere. The term "shooting star" is a colloquial, poetic reference to the visible streak of Light produced by this process, scientifically known as a meteor.
