A long-distance video link between aspiring students and their heroes on board China's space station.

From  locations across countries of the Shanghai Cooperation Organization, they put their burning questions to the taikonauts.

The Shenzhou crew covered everything from how zero-gravity affects muscle strength to their favourite pass-times in space.

Cai Xuzhe, a taikonaut who landed back on earth last winter, was on the ground for the session, with an invitation.

CAI XUZHE Taikonaut "I am so glad to see the passion young people have for space. I hope today has inspired you. And I look forward to the future when you join us as astronauts, and work together to explore the universe, and build a beautiful home for all mankind."

ZHANG MING SCO Secretary-General "Young people are the future of the [Shanghai Cooperation Organization]. Space is a place full of dreams. We hope that SCO youth can get to know each other more, explore space and go for their dreams."

Students of different ages took part in the Space Station link-up.

WU HAIHUI "My dream is to be like taikonaut Cai Xuzhe and [to] roam space. This painting represents us flying together in space, which means my dream has come true. In the future, I hope to become an astronaut like Uncle Cai and contribute to our country."

BATBOLD KHANGAL "I wish to invite taikonauts to Mongolia."

PODKOVYROV KIRILL "I still want to ask if they can swim on the China Space Station."
