Dictionary of Space Concepts
The Dictionary of Space Concepts (DSC) provides not only the basis for the advanced English language classes of the Multilingualism Programme; it also serves as larger online support platform for all UNIVERSEH students, with the aim of training specific space terminologies across various fields connected to the space sector. The DSC combines core space concepts and with helpful illustrations, all in an open-project format, which is freely available to everyone inside and outside UNIVERSEH. We welcome your contributions, comments, and expertise!

Falcon 9 vertical at Vandenberg Air Force Base. wikimedia commons. https://commons.wikimedia.org/w/index.php?curid=64851825 Definition:Falcon 9 is the world's first orbital class reusable rocket, created and manufactured by SpaceX. 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 Short Definition: 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.
