Woomera is recognised as Historic Place by American Institute for Aeronautics and Astronautics (AIAA).
Click the first link below for an introduction to this hobby. Each link describes a set of philatelic covers produced to commemorate a space project, whether rocket or missile launch or any other event tied to space research. If anyone would like a better image for their records please email me. Also for those people who are interested in collecting these items I have quite a selection of all types of envelopes to trade or swap.
