What is biomimetics?
Biomimetics is a research discipline at the interface of biosciences and technology. At first, biological systems are examined for their technical properties using engineering methods. The results are expressed in a technical language and hence the knowledge is transferred to the technical disciplines giving inspiration to improved designs or even new concepts.
Famous examples of early biomimetic approaches are found in the work of Leonardo Da Vinci and Otto Lilienthal who deduced the conceptual design of airplanes from bird flight. More recent examples of bio-inspired technical solutions are, e.g., Velcro and particle repellent surfaces (lotus flower, insect wing membranes).
Biomimetics does not mean copying nature. It rather expects the researcher to extract the functional principle and to transfer the knowledge as such. In extreme, this can lead to bio inspired computer algorithms (e.g. genetic algorithms, evolution strategy, computer aided optimization of mechanical parts).

Collapse overview
The environmental conditions during different space missions put a great variety of demands on the mechanical design of spacecraft. These include a strong tolerance towards vibrations and temperature differences. High package density, deployability, and lightweight design are other key demands that have to be met.
