The Expedition-21 Artwork

An early sketch of the patch made by Frank de Winne's wife Lena, and the final artwork with names. A version without names was only released by NASA so far.

2009 is a special year in ISS history. Long-awaited permanent crew of 6 is working on-board. Achieving permanent 6 crew is such a major milestone that all symbolism of the patch is built upon number 6.

The central element of the patch is inspired by a fractal of six. The concept of the fractal is "self-similarity". It is symbolically representative of team work as a crew: basic element - a crew member - is in a way similar to the others, but together six of them form a much more complex and multifaceted entity with infinite capabilities. Fractal is related to space because you can go to infinity looking at a fractal at different scales, like in the universe.

The contour shape has 6 tips. Smoothly flowing into each other the shape is geometrically sound and at the same time reminds of a leaf. It represents symmetry and ecological harmony.

Three sections represent: children on Earth in bright Sun - our future and reason why we explore and invest into the future. The Sun has 7 rays - number of luck and happiness which transcends cultures. In order to succeed in future human space exploration today we fly Soyuz and Shuttle to the ISS in low Earth orbit; our next goals are Moon and Mars.

Moon in "young" as a symbol is potential growth. Six stars in deep space represent the current crew and possible later exploration crew.

The Expedition 21 patch was designed by Frank de Winne's wife Lena.
