Korea’s first astronaut, Yi So-yeon, met with United Nations Secretary-General Ban Ki-moon on the first anniversary of her trip to space Wednesday.

The U.N. said Yi visited its headquarters in New York on Tuesday to meet with Ban before ending her four-day visit to the U.S.

This was the second time for the two Koreans to meet. Yi met Ban in July to give him a U.N. flag she carried to the International Space Station in April.
