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.

It is a reusable, two-stage rocket capable of transporting both people and payloads into Earth's orbit and beyond. Reusability allows to reuse the most expensive parts of the rocket, which diminishes the cost of space access. The standard parameters of the rocket are: Height - 70 m / 229.6 ft Diameter - 3.7 m / 12 ft Mass - 549,054 kg / 1,207,920 lb The engine used in production of Falcon 9 is the Merlin, which uses grade kerosene (RP-1) and liquid oxygen as rocket propellants in a gas-generator power cycle. The Merlin engine was originally designed for recovery and reuse. Falcon 9 has already been used in numerous missions or tests (Crew-1 Mission, Crew-2 Mission, Crew-3 Mission, DART Mission) and is planned to be launched in the next ones (for example Polaris Dawn in the last quarter of 2022). Sample Sentence(s):"This rocket is the Falcon 9 that successfully reached orbit after 9 minutes and 38 seconds on its maiden test flight." Translations:

Fluid shift in the human body | ||

 Image Source: S, M. (2023, June 01). Illustration of fluid distribution. self. self-made The fluid shift in the body is an adaption to the reduced gravitation force in space. This results in a shift of the body fluids from the lower body to the upper body. Detailed Definition: When a human body is placed on the earth surface, it has a hydrostatic (gravitational) blood pressure gradient and every body region has a different arterial pressure. In the reduced gravity of space, the hydrostatic pressure in the arteries and veins is altered to a homogeneous arterial pressure in all regions (which is the original arterial pressure of the hearth), which results in the shifted fluid distribution through the body. The human body reduces the volume of the total fluid and after the space resident, the fluid is shifted because of the returned gravity force. This phenomenon can cause several issues like cardiac arrhytmia, muscular athropy and visual problems (because the globe is flattened, the blood flow is changed slightly and the diamteter of the optical nerve can increase). Etymology: fluid - Latin fluidus ("fluid, flowing, moist") shift - Proto-Germanic skiftan (" to divide, change, seperate") Sample sentence(s): A medical
effect of a space flight may be a fluid shift. Nasa is studying
the effect of the fluid shift and how it affects changes in vision.
