Deutsch: Dämpfung / Español: Amortiguación / Português: Amortecimento / Français: Amortissement / Italiano: Ammortizzazione /
Damping in the space industry context refers to the process of reducing or dissipating unwanted vibrations, oscillations, or oscillatory motion in spacecraft, satellite systems, and other space-related equipment. Effective damping is crucial to ensure the stability, performance, and longevity of these systems, particularly during launch, operation, and maneuvers in space. It involves the use of various techniques and materials to control and minimize vibrations.
Deutsch: Gefahr / Español: peligro / Português: perigo / Français: danger / Italiano: pericolo
Danger in the space industry refers to any potential risk or hazard that could jeopardize the safety of astronauts, the integrity of spacecraft, the success of space missions, or the sustainability of space activities. Given the inherently hostile environment of space, the concept of danger encompasses a wide range of scenarios, including mechanical failures, environmental threats, and human errors.
The Defense Advanced Research Projects Agency (DARPA) is a research and development agency of the United States Department of Defense responsible for the development of emerging technologies for use by the military.
Deutsch: Dawn (Raumsonde) / Español: Dawn (sonda espacial) / Português: Dawn (sonda espacial) / Français: Dawn (sonde spatiale) / Italiano: Dawn (sonda spaziale)
Dawn in the space industry context refers to a NASA space mission aimed at studying two of the three known protoplanets of the asteroid belt, Vesta and Ceres, to gain insights into the formation and evolution of the early solar system. Launched on September 27, 2007, the Dawn spacecraft embarked on a journey to explore Vesta and Ceres, which are believed to have accreted early in the history of the solar system and to represent different stages in the evolution of rocky planets. Dawn is notable for being the first spacecraft to orbit two extraterrestrial bodies during its mission and for using ion propulsion, which allowed it to change orbits and visit both objects.
DC --->Direct Current
In the space industry context, DC-DC (Direct Current to Direct Current) refers to electronic devices or converters that transform direct current (DC) electrical power from one voltage level to another. These converters are crucial components in spacecraft systems, where they are used to adapt the power generated by solar panels or batteries to the various voltage requirements of onboard instruments, subsystems, and payloads.
Deutsch: Verzögerung / Español: Desaceleración / Português: Desaceleração / Français: Décélération / Italiano: Decelerazione
In the space industry context, deceleration refers to the reduction in speed or velocity of a spacecraft or object in space. It is a critical maneuver in various phases of a space mission, including orbital insertion, re-entry into the Earth's atmosphere, and landing procedures. Deceleration can be achieved through various means, such as the use of thrusters, atmospheric drag, or gravity assists, and is essential for safely navigating and positioning spacecraft within the targeted orbit or landing site.
Deutsch: Erforschung des tiefen Weltraums / Español: Exploración del espacio profundo / Português: Exploração do espaço profundo / Français: Exploration de l'espace lointain / Italiano: Esplorazione dello spazio profondo
Deep space exploration refers to the investigation and study of outer space beyond Earth's immediate vicinity, typically involving missions to the Moon, Mars, the outer planets, and beyond.
Deutsch: Tiefraummission / Español: Misión al espacio profundo / Português: Missão no espaço profundo / Français: Mission dans l'espace lointain / Italiano: Missione nello spazio profondo
Deep Space Mission in the space industry context refers to any space mission that goes beyond Earth's lower orbit to explore further celestial bodies or areas of space. These missions may target other planets, asteroids, comets, or even the outer solar system and beyond, involving scientific investigations to understand more about the universe and our place within it.
The defense industry is a broad term that encompasses a range of companies, organizations, and activities involved in the production of goods and services related to national defense.
Deutsch: Verformung / Español: Deformación / Português: Deformação / Français: Déformation / Italiano: Deformazione /
In the intricate world of space exploration and engineering, the term deformation holds significant importance. It refers to the alteration in shape or structure of spacecraft, components, or materials under the extreme conditions of space travel. Deformation can impact the safety, functionality, and longevity of space missions. This article delves into the concept of deformation in the space industry, presents examples of its occurrence, outlines associated risks, and sheds light on its historical context and legal considerations. Additionally, we will draw parallels with similar phenomena in other industries that demand precision and reliability.
At first Deimos is a moon of Mars, the smaller and outermost of Mars two natural satellites.
Delta refers to a type of wing shape that is triangular in planform, with the leading edge forming a straight line and the trailing edge forming a right angle. This wing shape is characterized by its high lift to-drag ratio and is often used on aircraft that are designed to fly at high speeds, such as military jets and supersonic aircraft.
Deutsch: Deorbitierung / Español: Desorbitación / Português: Desorbitagem / Français: Désorbitation / Italiano: Disorbita
Deorbiting in the space industry context refers to the process of intentionally lowering a spacecraft or satellite from its operational orbit toward a controlled re-entry into the Earth's atmosphere or to a disposal orbit. This is a crucial part of space mission planning and operations, aimed at mitigating space debris and ensuring the long-term sustainability of space activities. Deorbiting can be achieved through various means, including the use of the spacecraft's remaining propellant to alter its trajectory, deploying drag sails to increase atmospheric drag and accelerate orbital decay, or using external forces such as robotic spacecraft for removal.
Deutsch: Abhängigkeit / Español: Dependencia / Português: Dependência / Français: Dépendance / Italiano: Dipendenza
Dependence in the space industry refers to the reliance on specific technologies, resources, or partnerships that are essential for the successful execution of space missions. This can include dependence on international collaborations, critical materials, or specialized technologies and infrastructure.
Deutsch: Darstellung / Español: Representación / Português: Representação / Français: Représentation / Italian: Rappresentazione
Depiction in the space industry context refers to the visual representation or illustration of space objects, phenomena, missions, and concepts. This can include artistic impressions, diagrams, computer-generated imagery (CGI), and real photographs captured by spacecraft and telescopes.
Deutsch: Erschöpfung / Español: Agotamiento / Português: Esgotamento / Français: Épuisement / Italiano: Esaurimento
In the context of the space industry, depletion refers to the reduction or exhaustion of resources or materials that are crucial for space missions. This term often applies to natural resources on Earth used in the production of spacecraft and satellites, such as rare metals and minerals, or to the consumable resources on a spacecraft, like fuel or life support systems. Depletion in space can also refer to the diminishing availability of orbital slots for satellites, which are becoming increasingly crowded due to the growing number of satellite launches.
