AACG and space flight

The American Association for Crystal Growth (AACG) has had two members in space, NASA scientist Roger Crouch in July 1997 (Roger brought the AACG banner and a packet of membership cards on the journey) and Lodewiijk van den Berg in April 1985 (the membership card for 1999 with the NASA space shuttle logo).
