Glossary S

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: 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.

Deutsch: Dusche im Kontext der Raumfahrtindustrie / Español: Ducha en el contexto de la industria espacial / Português: Chuveiro no contexto da indústria espacial / Français: Douche dans le contexte de l'industrie spatiale / Italiano: Doccia nel contesto dell'industria spaziale

Shower in the space industry refers to a system designed for astronauts to clean themselves while on space missions. Given the microgravity environment of space, traditional methods of bathing are not feasible, so specialized shower systems are developed to maintain hygiene for astronauts aboard spacecraft and space stations.

Deutsch: Raumfähre / Español: Transbordador / Português: Ônibus Espacial / Français: Navette / Italiano: Navetta /

A shuttle is a spacecraft that is designed to transport people, cargo, or both between Earth and a space station or other destination in space. Shuttles are typically reusable vehicles that can be launched into space and then land back on Earth, allowing them to be used multiple times.

SiGe, or silicon–germanium, is an alloy with any molar ratio of silicon and germanium. It is commonly used as a semiconductor material in integrated circuits (ICs) for heterojunction bipolar transistors or as a strain-inducing layer for CMOS transistors.

Deutsch: Signal / Español: Señal / Português: Sinal / Français: Signal / Italiano: Segnale /

In the aerospace context, a signal refers to a message or piece of information that is transmitted between two or more devices or systems. Signals can be transmitted through various means, such as electrical, optical, or wireless, and can be used to convey a wide range of data, such as control commands, sensor readings, or communication messages.

Deutsch: Signalstörung / Español: Interferencia de Señal / Português: Interferência de Sinal / Français: Interférence de Signal / Italiano: Interferenza del Segnale

Signal interference in the space industry refers to the disruption or degradation of communication signals between spacecraft, satellites, and ground stations. This interference can significantly impact the performance and reliability of space missions, affecting data transmission, navigation, and other critical functions.

Deutsch: Bedeutung / Español: Significado / Português: Significância / Français: Signification / Italiano: Significato

In the space industry context, "significance" refers to the importance or impact of space-related activities, technologies, and discoveries on scientific advancement, economic growth, national security, and human understanding of the universe. The significance of the space industry encompasses a wide range of areas, including the development of satellite technologies for communication, weather monitoring, and navigation; exploration missions to other planets and celestial bodies; and the potential for space tourism and the utilization of space resources.

Silicon is a chemical element, with the symbol Si and atomic number 14.

Deutsch: Silber / Español: Plata / Português: Prata / Français: Argent / Italian: Argento

Silver plays a crucial role in the space industry, primarily due to its unique properties, including excellent electrical conductivity, high thermal conductivity, and resistance to oxidation. These characteristics make it indispensable in various applications, particularly in electronics and thermal management systems used in spacecraft, satellites, and other space-related technologies.
