ISS037-S-001 (August 2012) --- Leonardo da Vinci's Vitruvian Man, created some 525 years ago, as a blend of art and science and a symbol of the medical profession, is depicted amongst the orbits of a variety of satellites circling the Earth at great speed. Da Vinci's drawing, based on the proportions of man as described by the Roman architect Vitruvius, is often used as a symbol of symmetry of the human body and the universe as a whole. Almost perfect in symmetry as well, the International Space Station, with its solar wings spread out and illuminated by the first rays of dawn, is pictured as a mighty beacon arcing upwards across our night skies, the ultimate symbol of science and technology of our age. Six stars represent the six members of Expedition 37 crew, which includes two cosmonauts with a medical background, as well as a native of Da Vinci's Italy.
The design for insignia for space station flights is reserved for use by the crew members and for other official use as the NASA Administrator may authorize. Public availability has been approved only in the form of illustrations by the various news media. When and if there is any change in this policy, which is not anticipated, it will be publicly announced.
