This study examines how the Korean satellite development program was established in Korean society and expanded its boundaries through tracking the history of KAIST Satellite Technology Research Center (SaTReC) from 1989 to 2013. Based on documentary analysis, I argue that the Korean satellite development program was started by an autonomous research group, SaTReC, and evolved into a government-led program. This process is divided into four periods based on the boundaries of the Korean satellite development program: 1989-1993, 1994-1999, 2000-2005, and 2006-2013. Although the role of SaTReC was reduced in the Korean satellite development program, the Korean satellite development program expanded its boundaries from SaTReC to the Government and Korea Aerospace Research Institute (KARI), to industry, and finally to other countries and the public. New actors of the Korean satellite development program raised according to the expansion of boundaries. This study shows that the Korean satellite program continuously has expanded its boundaries to find its position in society under environmental change and provides insights for the future of the Korean satellite development program in the new era.
