Yeon-seok Chae is an engineer. He has a Ph.D in Aerial Cosmic Engineering and has steered rocket development in Korea for 20 years. He was always wondering what was living out there in the space and enjoyed watching stars. He was triggered by the news in 1961 when Soviet Union had launched the first manned spaceship ever in human history. Chae says "Is there a successful life? I think what's more important is doing what you like doing, how long you do it. If you try hard, you can make yesterday's dream a reality. I am a living proof, so have some confidence."
