After the initial news was reported on Monday, little has been said in South Korean media about the death of U.S. astronaut Neil Armstrong, the first man on the moon.

We asked South Korea's first – and still only – space traveler, Yi So-yeon, for her thoughts about him. Ms. Yi in 2008 joined the crew of a Russian Soyuz flight to the International Space Station.

She was born in 1978, nearly a decade after Mr. Armstrong's moon flight and several years after the moon missions ended. Yet Ms. Yi is one of only about 530 people to fly to space, still one of the rarest of all human experiences.

Her note:

"Landing on the moon was an event in the history book for me. Whenever I think of the Apollo missions or the moon landing, the black and white image on the chubby, Braun tube television comes to my mind first.
