Korea's first astronaut Yi So-yeon and backup Ko San on Thursday reported mission complete to Education, Science and Technology Minister Kim Doh-yeon.

The two reported the results of their training and space missions, delivering to Kim the ministry's flag, which was used for a space performance while in orbit.

The minister said he appreciated their efforts, asking them to continue to work for the development of the nation's space exploration and science.

The ministry will publicly announce the results of the space mission around June tenth before officially ending its two-year project to send a Korean into orbit.
