Deutsch: Umlaufbahn / Español: Órbita / Português: Órbita / Français: Orbite / Italiano: Orbita /
An orbit is the path that an object follows as it travels around another object under the influence of gravity. The object that is being orbited is called the central body, and the object that is orbiting is called the satellite.
Deutsch: Bahnkorrektur / Español: Corrección de Órbita / Português: Correção de Órbita / Français: Correction d'Orbite / Italiano: Correzione di Orbita
Orbit correction in the space industry refers to the adjustments made to a spacecraft’s trajectory to maintain or change its orbit around a celestial body, such as Earth. These adjustments are necessary to ensure the spacecraft remains on its intended path, achieves mission objectives, or avoids potential collisions with other objects in space.
Deutsch: Weltraummüll / Español: Basura Espacial / Português: Detritos Orbitais / Français: Débris Orbitaux / Italiano: Detriti Orbitali
Orbital Debris, also known as space debris or space junk, refers to non-functional, human-made objects in Earth's orbit. These include defunct satellites, spent rocket stages, fragments from satellite collisions, and other discarded materials. Orbital debris poses a significant risk to active spacecraft, satellites, and the International Space Station (ISS) due to the high velocities at which these objects travel, which can cause severe damage upon impact.
Deutsch: Orbitaltransfer / Español: Transferencia Orbital / Português: Transferência Orbital / Français: Transfert Orbital / Italiano: Trasferimento Orbitale
Orbital transfer in the space industry refers to the process of moving a spacecraft from one orbit to another. This is a critical maneuver used to position satellites, space probes, and other spacecraft into their designated operational orbits after launch or during their mission.
Deutsch: Orbiterschiff / Español: Nave orbitadora / Português: Orbitador / Français: Orbiteur / Italiano: Orbiter/
An "orbiter" in the aerospace context refers to a spacecraft or vehicle that is designed to orbit a celestial body, such as a planet, moon, or asteroid. It is equipped with propulsion systems and guidance systems that allow it to maintain its orbit around the body and make adjustments as needed.
Deutsch: Ausrichten / Español: Orientar / Português: Orientar / Français: Orienter / Italian: Orientare
Orient refers to the process of aligning or positioning a spacecraft or satellite in a specific direction or attitude. This alignment is crucial for various operations, including communication, navigation, scientific observations, and maintaining the stability of the spacecraft.
In the aerospace context, an Original Equipment Manufacturer (OEM) is a pivotal player in the industry's intricate ecosystem. These companies are the architects of flight, designing, manufacturing, and delivering the essential components, systems, and even entire aircraft and spacecraft that define modern aviation and space exploration.
Orion is a spacecraft developed by NASA for the purpose of human deep space exploration. It is designed to be used for missions to the Moon, Mars, and other destinations beyond low Earth orbit. The spacecraft consists of a Crew Module and a Service Module, and is launched on top of the Space Launch System (SLS) rocket.
Deutsch: Orion-Raumschiff / Español: Nave Espacial Orión / Português: Nave Espacial Orion / Français: Vaisseau Spatial Orion / Italiano: Nave Spaziale Orion
Orion spacecraft in the space industry refers to the multi-purpose crew vehicle developed by NASA, designed to transport astronauts beyond low Earth orbit (LEO), to the Moon, Mars, and other deep space destinations. This spacecraft is a crucial component of NASA's Artemis program, which aims to return humans to the Moon and eventually send astronauts to Mars.
In the space industry context, oscillation refers to the repetitive variation, typically in time, of some measure about a central value (often a point of equilibrium) or between two or more different states. In space systems and celestial mechanics, oscillations can be observed in a variety of phenomena, from the vibrations of spacecraft structures to the orbital motions of celestial bodies. Understanding and managing these oscillations are crucial for the stability, control, and longevity of space missions.
English: OSIRIS-REx / Deutsch: OSIRIS-REx / Español: OSIRIS-REx / Português: OSIRIS-REx / Français: OSIRIS-REx / Italiano: OSIRIS-REx
In the space industry context, OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer) is a NASA asteroid study and sample-return mission. Launched on September 8, 2016, its primary goal is to visit the near-Earth asteroid Bennu, thoroughly study it, and collect samples to bring back to Earth for detailed analysis. This mission aims to provide valuable insights into the early solar system's formation and evolution, organic compounds that could have led to the origin of life on Earth, and potentially how to deflect asteroids that could pose a threat to Earth.
English: Outgassing / Deutsch: Ausgasung / Español: Desgasificación / Português: Desgaseificação / Français: Dégazage / Italiano: Degassamento /
In the space industry, "outgassing" refers to the process by which volatile substances trapped within materials or components release gases when exposed to the vacuum and extreme conditions of outer space. This phenomenon is of paramount importance for spacecraft and satellite design and poses significant challenges in ensuring mission success and longevity. This article will explore the concept of outgassing in the space industry, delve into various examples of outgassing-related issues, assess associated risks, and discuss historical context and legal considerations. Additionally, we will draw parallels with similar processes in other industries to highlight the importance of managing outgassing in space technology.
In the aerospace context, an oxidizer is a chemical compound that supplies oxygen to a fuel, enabling it to burn. Oxidizers are a critical component of rocket propulsion systems, as they provide the oxygen needed for the combustion of the fuel. Without an oxidizer, the fuel would not be able to burn and generate the necessary thrust to power the rocket.
Oxygen is a chemical element with the symbol O and the atomic number 8
In the aerospace context, oxygen refers to the gas that is used by the crew and passengers of aircraft and spacecraft to breathe.
English: Ozone / Deutsch: Ozon / Español: Ozono / Português: Ozônio / Français: Ozone / Italiano: Ozono /
Ozone, a molecule composed of three oxygen atoms (O3), is a well-known component of Earth's atmosphere. While ozone is commonly associated with the protection of the Earth's surface from harmful ultraviolet (UV) radiation, its presence and significance extend beyond our planet. In the space industry context, ozone plays a crucial role in various applications, including spacecraft design, radiation shielding, and as a diagnostic tool for space exploration. This article will delve into the multifaceted role of ozone in the space industry, exploring its examples, risks, application areas, historical significance, and legal considerations.
