Deutsch: Navigation und Steuerung / Español: Navegación y Control / Português: Navegação e Controle / Français: Navigation et Contrôle / Italian: Navigazione e Controllo
Navigation and Control in the space industry refers to the technologies and processes used to guide spacecraft and satellites to their intended destinations and manage their movements and orientations. These systems are crucial for ensuring the success of space missions by enabling precise trajectory planning, real-time adjustments, and stable positioning.
In the space industry, Navigation and Control systems play a pivotal role in the success of missions. Navigation encompasses the methods and tools used to determine the spacecraft's position and velocity in space. This includes the use of onboard sensors, ground-based tracking systems, and astronomical observations. Control involves the mechanisms and strategies used to adjust the spacecraft's path and orientation to achieve mission objectives. This includes attitude control, which manages the orientation of the spacecraft, and orbit control, which adjusts the spacecraft's trajectory.
Historically, early space missions relied heavily on ground-based navigation and control systems. As technology advanced, onboard autonomous systems were developed, allowing spacecraft to navigate and control themselves with minimal input from ground stations. This autonomy is essential for deep-space missions where communication delays make real-time control from Earth impractical.
Legal and regulatory frameworks also influence navigation and control systems. International treaties and agreements, such as the Outer Space Treaty, establish guidelines for the peaceful use of space and the avoidance of harmful interference between space objects. Compliance with these regulations is crucial for the coordination of space traffic and the prevention of collisions.
Navigation and Control systems are utilized in various areas within the space industry, including:
Navigation and control systems in space missions face several risks and challenges, including:
Navigation and Control systems are fundamental to the space industry, enabling precise guidance and management of spacecraft and satellites. These systems ensure mission success through advanced technologies for trajectory planning, real-time adjustments, and stable positioning. They are applied across various mission types, from satellite operations to interplanetary exploration, and face challenges such as the harsh space environment and increasing space traffic.

"Nondestructive inspection" (NDI) is a process or technique used to inspect the condition of a material, component, or system without causing any damage to it. NDI techniques are used to identify and assess defects or flaws in materials or components, such as cracks, corrosion, or other types of damage, without having to disassemble or destroy the item being inspected.
NewSpace is a term that refers to the emerging commercial space industry, which includes companies and organizations that are involved in the development and operation of new space-related technologies and services.
English: Nickel / Deutsch: Nickel / Español: Níquel / Português: Níquel / Français: Nickel / Italiano: Nichel /
Nickel in the space industry context refers to the use of nickel and nickel-based alloys in the construction of spacecraft, space probes, and various space components. Nickel is valued for its unique properties, including high strength, resistance to extreme temperatures, and excellent resistance to corrosion, making it an ideal material for various aerospace applications. In this article, we will explore the significance of nickel in the space industry, its various applications, and provide examples of how it is used in space missions.
Nitrogen is a chemical element with the symbol N and atomic number 7.
In the aerospace context, nitrogen is a gas that is used in a variety of applications. Nitrogen is an inert gas, which means it does not react with other elements or compounds under normal conditions, making it safe to use in aircraft and spacecraft.
Deutsch: Lärmunterdrückung / Español: Cancelación de ruido / Português: Cancelamento de ruído / Français: Annulation du bruit / Italiano: Cancellazione del rumore
Noise cancellation in the space industry refers to the techniques and technologies used to reduce or eliminate unwanted sound and vibrations that can interfere with the functioning of spacecraft and the well-being of astronauts. This includes both active noise control, which uses sound waves to cancel out unwanted noise, and passive noise control, which involves insulating materials and structural designs to block or absorb noise.
Deutsch: Nomex / Español: Nomex / Português: Nomex / Français: Nomex / Italiano: Nomex
Nomex in the space industry context refers to a meta-aramid material known for its high resistance to heat and flames. Developed in the early 1960s by DuPont, Nomex is used extensively in applications where thermal, chemical, and radiation resistance is critical for safety and performance. This material is particularly notable for its use in astronaut suits and other protective gear in aerospace environments.
Deutsch: Nicht-pyrotechnisch / Español: No pirotécnico / Português: Não pirotécnico / Français: Non-pyrotechnique / Italiano: Non pirotecnico /
In the space industry context, the term non-pyrotechnic refers to mechanisms or systems that do not rely on pyrotechnics (explosive or combustible chemical reactions) to function. These systems are crucial for various operations in spacecraft, satellites, and launch vehicles, offering a safer, more reliable, and often reusable alternative to traditional pyrotechnic devices. Non-pyrotechnic technologies are used in deployment mechanisms, separation systems, and other critical functions where precision and reliability are paramount.

Notices to Airmen (NOTAMs) are essential notifications issued by aviation authorities to inform pilots and other personnel about real-time information concerning the condition or changes in any component of the National Airspace System (NAS). In the context of the space industry, NOTAMs are crucial for ensuring the safety and coordination of space launch and reentry operations, preventing conflicts between air traffic and space activities.
Deutsch: Düse / Español: Tobera / Português: Bocal / Français: Tuyère / Italiano: Ugello
In the context of the space industry, a nozzle is a crucial component of rocket engines, designed to accelerate the flow of hot gases from the combustion chamber outwards, creating thrust that propels the rocket into space. This acceleration is achieved by channeling the gases through a narrowed passage, which increases their velocity.
The National Radio Astronomy Observatory (NRAO) is a federally funded research and development center of the United States National Science Foundation operated under cooperative agreement by Associated Universities, Inc. for the purpose of radio astronomy.
