NASA Administrator Charlie Bolden and European Space Agency Director-General Jean-Jacques Dordain shared reflections and stories in the Masters with Masters #5 program. They traded ideas about international collaboration and fielded questions from the audience in a lively discussion moderated by Academy Director Dr. Ed Hoffman at the 61st International Astronautical Congress in Prague on September 28, 2010. Dordain emphasized that cooperation among space agencies is strengthened by personal relationships. Bolden spoke about collaboration in terms of diversity and inclusion. Both agreed that competition and cooperation were not mutually exclusive - We need competition, but provided that that competition is organized to reach common objectives, said Dordain. I think that cooperation is to set the common objectives: what are we ready to go do together? I think that is the sense of cooperation. But to reach these common objectives, I think that competition is very healthy.
