The end of the shuttle era is represented by the five historical space shuttles soaring together into space as a final farewell. Above a rising sun, dawn of a new era for mankind exploration of space, and leaving behind their golden flight paths, each one of the shuttles is going into a different direction, leading the way for future voyages and generations of spacecrafts. Finally, the 14 stars are paying homage to the lost crew members of the Challenger and Columbia expeditions.
