Issues and Vision
-University Nano-satellite program is at early development stage, but its future prospect is promising in Korea.
- The main obstacles are lack of experience and infrastructure, especially finding launch opportunity.p y g pp y
- Need international cooperation for jump-start. Short-term student exchange and information sharing are recommendedexchange and information-sharing are recommended.
- Should work hard to find new mission concept and break-throughgtechnologies.
University space consortium is a good starting point which could- University space consortium is a good starting point, which could increase government funding opportunity.
: Strong need to diversify space programs
