One of these books entitled "108 Minutes in Space" documents the first flight of a human in space. He founded a magazine of space exploration, and is currently editor in chief of the "Latin-American Journal of Space Science and Technology". Pablo has written more than 35 technical papers on space engineering and life support systems presented at international congresses. He belongs to a number of professional aerospace engineering societies. He was selected Regent of the United Societies in Space (USIS) in 2000. During 2000 he was co-founder of the Latin American Space Association (Asociacion Espacial Latinoamericana www.alespacio.org). Pablo was elected as Regional Representative (South America) of the Space Generation Advisory Council in Support of the United Nations Program on Space Applications.
