Below are listed some random articles of the glossary.

Overallocation

Deutsch: Überbelegung / Español: Sobreasignación / Português: Superalocação / Français: Surallocation / Italiano: Sovrallocazione

Overallocation in the space industry refers to the assignment of resources—such as payload capacity, crew time, or ground station availability—beyond their sustainable or optimal limits. This phenomenon occurs when mission planners or operators allocate more tasks, experiments, or operational demands than the system can reliably support, often due to competing priorities, scheduling constraints, or unforeseen contingencies. While overallocation can temporarily maximize resource utilization, it frequently leads to inefficiencies, increased risk, and potential mission degradation if not carefully managed.

Embedded system

Deutsch: Eingebettetes System / Español: Sistema embebido / Português: Sistema embarcado / Français: Système embarqué / Italiano: Sistema incorporato

Embedded system in the space industry refers to a specialised computer system integrated within spacecraft, satellites, launch vehicles, and ground support equipment to perform dedicated functions. These systems are typically designed for real-time operation, high reliability, and resilience to the harsh conditions of space, controlling everything from propulsion and navigation to communication and payload management.

Complexity and Weight

Deutsch: Komplexität und Gewicht / Español: Complejidad y Peso / Português: Complexidade e Peso / Français: Complexité et Poids / Italiano: Complessità e Peso

Complexity and weight are Critical factors in the Space industry, influencing the design, Development, and Operation of Spacecraft and related technologies.

Timer

Deutsch: Timer / Español: Temporizador / Português: Temporizador / Français: Minuteur / Italiano: Timer

A timer is a crucial component in the space industry, ensuring precise timekeeping and synchronization for various operations. Timers are used to manage mission-critical tasks, from launch sequences to satellite operations, making them indispensable in space exploration and satellite communications.
