Glossary N

A nanosatellite (nano satellite, nanosat) is a small satellite with a weight between 1 and 10 kg.

The National Aeronautics and Space Administration (NASA) is a U.S. government agency that is responsible for the nation's civilian space program and for conducting research and development in the field of aeronautics.

"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.

Neptune is the eighth planet from the Sun and the farthest known planet in the Solar System. It is the fourth-largest planet in the Solar System by diameter, the third-most-massive planet, and the densest giant planet.

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: 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.

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.

In the aerospace context, "nucleus" can refer to a few different things, including:
