IN CONCLUSIONBENEFITS TO BE DERIVED FROM THE FORMATION OF A SOUTH AFRICAN NATIONAL SPACE AGENCY:

1- The development and sale of local space technologies and products to international clients deriving direct foreign investment and revenues for the Republic

2- The strengthening of existing space research and scientific relationships between the Republic and developed agencies such as the National Aeronautics and Space Administration (NASA), the European Space Agency (ESA) and the Russian Space Agency

3- Provide a platform for further agreements and scientific partnerships between the Republic and other international space agencies (e.g. the Indian, Japanese, Canadian and Chinese space agencies as well as other African space agencies such as the Kenyan, Nigerian, Moroccan and Algerian space agencies)

4- Provide political support to the development and use, by the Republic, of space for peaceful purposes which in turn allays the fears of foreign investors wishing to finance local commercial space endeavours

5- Strengthen the fundamental objective of NEPAD, namely, the reduction of Africa's dependence on foreign technologies

6- Positively enhance the global perception of the Republic's scientific and engineering capabilities

7- Enhance manufacturing opportunities and the industrial reputation of the Republic as a producer of cost effective high technology products and in so doing, develop and retain local scientific and engineering expertise and provide for industry wide job creation

8- and possibly most importantly, inspire and encourage the youth of South Africa to dream, excel in mathematics and science and “reach for the stars”.

As a stakeholder in the development of a profitable and sustainable South African space industry, and as a developer of world class aerospace technologies, MARCOM is in full support of the proposed South African National Space Agency Bill [B20-2008] and furthermore deems the establishment of a South African National Space Agency an essential political foundation to the development and support of a healthy aerospace industry within the Republic.
