The government says astronaut Yi Soyeon's mission is going smoothly on her fifth day at the International Space Station, adding that she'll bring the results of her experiments when she returns to Earth this weekend.

The Education, Science and Technology Ministry says data on six experiments including one on face shape changes and data on atmospheric conditions will be brought back on flash memory cards. Yi will back up her data on hard disk.

Observation data of the Earth and the inside of the space station, along with the results of five other experiments, will also be brought home on videotape.

In addition, Yi will bring back the Korean flag, Korean currency, scarves and postcards she took with her for a celebration at the space station.
