South Korea's first astronaut says she will do her best to help her country develop its own space technology.
The 29-year-old bioengineer Yi So-yeon told a news conference Monday after her return home that she will ''pay back'' the support the South Korean people gave for her trip to space.
Yi works for the state-run Korea Aerospace Research Institute.
The South Korean government paid Russia $20 million for her flight to the international space station aboard a Russian capsule earlier this month.
