The second edition of the children's science festival "Hello Space! Bulgaria Calling" took place in "Sofia Tech Park". 19-year-old Tatiana Ivanova, who has been accepted into NASA's only academy for astronaut candidates, also answered questions of the visitors.

"Being human comes first. Yuri Gagarin was chosen because he was radiant and always smiling. You have to be a team player, to help others," Tatiana Ivanova, who dreams of becoming the first Bulgarian female cosmonaut, said.

She has been accepted to study "Space Engineering" with specialization in "Rocket Fuels" in Florida, USA. But education there is expensive and the young woman hopes that Bulgarian companies will support her in this venture, BTA reports.
