Gill, E.K.A. (author), Lisi, M. (author), Bousquet, M. (author), Larson, W.J. (author)The space sector needs highly trained personnel. This calls for a continuous learning process comprising post-graduate educational programs. However, the offered programs differ substantially in scope and characteristics, coverage and focus, quality and organization and lack inter-program coordination. To remedy this, a Virtual Space Academy has...conference paper 2008
