Dictionary of Space Concepts
What is the Dictionary of Space Concepts?
The Dictionary of Space Concepts (DSC) is a project by UNIVERSEH – the European Space University of Earth and Humanity. Starting in 2020, this Alliance of five European Universities decided to launch an online dictionary dealing with terms and concepts related to space sciences. It should be created and used by students, lecturers, researchers and citizens alike.
After an initial planning phase, the DSC was published in spring 2022. It opens up several opportunities for all members of the UNIVERSEH Alliance and interested citizens to contribute to the content of the DSC.
In our course "Terms and Concepts of Space" (to the registration) , students learn how to write a dictionary article and later on contribute several entries to the DSC. Students and other members of the UNIVERSEH Alliance can also submit articles for the DSC via an entry in here . Interested citizens can contribute in this entry platform.
Once submitted, these articles are reviewed by UNIVERSEH Alliance staff and, if necessary, edited before their publication in the Dictionary.
In this way, the DSC is a dynamic project that is constantly expanding in content and quality through constant contributions from students, staff and citizens.

By SpaceMusk - Own work, CC BY-SA 4.0, https://commons.wikimedia.org/w/index.php?curid=76817044 Short Definition: A Moon Base is a type of facility on the surface of the moon, that could help us building up a colony on the moon.It could be the next frontier on our endeavour to become intergalactic and it could be a steppingstone to regions, that are not feasibly reached by spacecraft from earth, or it could become a centre for industry. In this way we could outsource industry or practices, that are not likely to become CO2-neutral soon. Detailed Definition:
A Moon Base is a type of facility on the surface of the moon, which enables human activity on the moon. As China and USA chose the same locations for their proposed moon bases, it could lead to the next smaller space race to the moon, only this time the mission would be to stay on it and to leave a small team to colonize the moon. Ice from the poles could be melted to get Water and this in turn could be split by electrolysis to hydrogen and oxygen, which are the main ingredients for liquid rocket fuel. The moon base could be used as a steppingstone to far distances because the rocket fuel needed to transport cargo from the moon is much lower than the earth due to the decreased escape velocity. So, a moon base could be used as a stopover to other proposed ideas like asteroid mining or it could help the Mars base. To justify the high investment costs, the moon base needs to be economically viable sooner rather than later. The mining of important resources like aluminium, titanium, and helium -3, which is used to fuel fusion reactors, could be helpful, if it proves to be economically and ecologically viable. A few suggestions could make this project much more autonomous by producing living soil from lunar regolith and mixing the moons soil, regolith and a plant-based glue to produce a 3D-printing material, which will prove to be absolutely essential for this kind of project. Etymology:
Moon from Old English mōna Base from Latin basis and from Ancient Greek βάσις (básis) Sample Sentence(s):A Moon base could help with making fusion reactors more efficient, by having a higher abundance percentage of Helium-3, which is used as a fuel in those reactors. If a Moon base can prove to become autonomous, we could outsource some of our CO2- intensive industries to the moon, if it also proves to be economically viable French:base lunaire German: Mondbasis Polish: baza księżycowa Swedish: månbas Links to Videos/Articles: https://www.youtube.com/results?search_query=moon+base https://en.wikipedia.org/wiki/Moonbase https://www.nasa.gov/feature/goddard/2021/nasa-s-artemis-base-camp-on-the-moon-will-need-light-water-elevation/ | |||

MediaMedia Zenith & Nadir, DJ Jeffery, University of Nevada, Las Vegas, 2003 DefinitionsShort Definition Detailed Definition In medicine, nadir is predominantly used to describe blood cell counts at their lowest during chemotherapy. Each chemotherapy treatment comes with the nadir period. Figuratively, nadir means the lowest point and may be used to emphasize the state of one’s feelings, quality of activity and affairs. Etymology Sample Sentences A nadir image is a satellite image or an areal photo of Earth taken vertically in the downward alignment. During chemotherapy, the nadir time usually comes in about 10 days after the start of treatment, although this is mostly dependent on drugs given. The relationship between the USA and USSR reached its nadir in the 1980s.

The Mighty Orion Nebula from New Zealand. flickr. https://www.flickr.com/photos/67481624@N05/17243621226 Short Definition: Any kind of giant cloud that includes miscellaneous gas and dust; especially hydrogen, cosmic dust, and helium located in outer space. Detailed Definition: As the basic components of galaxies, nebulae were stars before they formed. During the formation phase of these stars, the gases released into space initiate a fusion reaction with hydrogen atoms and form the foundations of a new star. Thus, the universe continues to expand. Etymology: Ancient Greek (νεφέλη - nephélē): Cloud Sample Sentences: 'Today the term nebula generally refers exclusively to the interstellar medium.' 'A nebula that is visible to the human eye from Earth would appear larger, but no brighter, from close by.'

Short
Definition
After earning a degree in aeronautical engineering from Purdue University in 1955, Armstrong began working as a civilian research pilot for the organization that would later evolve into the National Aeronautics and Space Administration (NASA). In 1962, Armstrong joined NASA's space program and 7 years later, on July 20, 1969, he made history by stepping onto the surface of the moon, saying his iconic words, "That's one small step for [a] man, one giant leap for mankind." Following this achievement, Armstrong resigned from NASA in 1971. He then dedicated himself to teaching in the Department of Aerospace Engineering at the University of Cincinnati until 1979. He passed away in 2012 at the age of 82.

NEO (Near-Earth Object) | ||
---|---|---|
Source: Video from NASA explaining NEO: https://www.youtube.com/watch?v=r-OCcFnp2RA Short Definition:NEO, or near-Earth object, is a celestial body which is in the size range of meters to tens of kilometres, that orbits the sun and approaches the earth within the distance of 1.3 AU (astronomical units). Detailed Definition:Among the 600,000 known asteroids, only 20,000 of them are NEOs. To be classified as such, the object must be natural and cannot be manmade. Some of them could potentially hit the earth and for this reason, some organisation keep track of them everyday. Historically speaking, NEOs have had an impact of the earths geological and biological history. Most of the NEOs are Apollo asteroids (55.4%), meaning that they come from the Apollo asteroid group. The second most common are Amor asteroids (36.4%), and third most common are Aten asteroids (7.7%). Etymology:Acronym of "near-Earth object." Sample Sentence:An astronomer would for example say during a lecture: “The Amor asteroid, 433 Eros, was the first NEO discovered in 1898, by D. Witt of Berlin, Germany, using a photographic plate to record its position.” Translations:

Neutron star | |||
---|---|---|---|
Short Definition: A Neutron star is a celestial body
and is the collapsed core of a massive supergiant star that had a total mass of
about 10-25 solar masses. Compared to other stellar objects, they are much
smaller and much denser. Not counting black holes or hypothetical stellar
objects, they are the densest stellar object in the universe. Detailed Definition: A Neutron stars is a stellar object, which is only a few kilometres in
diameter, but has the mass of a star. So even compared to others stellar objects they have a mind-boggling density and are even so dense, that they are on the
cusp of becoming a black hole. Stars hold an equilibrium between the force of
gravity forcing plasma inwards, which in turn enables fusion of hydrogen to
helium, and this releases energy that pushes outwards. So the equilibrium is
directly linked to the amount of hydrogen available in stars. Breaking this equilibrium
in our sun would result in it transforming to a red giant and then to a white
dwarf. In those massive supergiant stars, gravity will prevail and will
compress the core to the density of an atomic nucleus, which in turn forces
heavier elements to fuse, and thus the outer layer will get bigger by a factor
of x100. After a time the heavier elements are fused to iron and can not be fused any more, so the fusion activity will cease, and the star will collapse to its
core. Electrons and Protons will be forced into each other and form Neutrons as
dense as in atomic nuclei, where nuclei are so densely packed, they form a
layer that is called nuclear pasta. Another interesting property is that they
are spinning really fast, which empowers their magnet fields and gives them the
strongest magnet field in our universe. Etymology: Neutron from Ne and uterà neutral +on ending from ion subatomic particle suffix Star from Proto-Indo-European rooth₂stḗrSample Sentence(s): The physics in the core of the Neutron stars are still largely unknown and are still subject of speculation. Scientists were able to detect gravitational
waves of two merging Neutron stars and confirmed the theory of Albert Einstein.
