Although China hasn't sent any space craft to the moon and the Mars yet, it has got three stones from them.

"Chinese explorers found nearly 10,000 stones fallen from space in the Antarctic area, including one from the moon and two from the Mars," said Ouyang Ziyuan, a member of the Chinese Academy of Sciences, at the ongoing 36th Committee on Space Research Scientific Assembly here Friday.

He said humanity has altogether obtained 26 stones fallen from the moon in the past.

In addition, human beings have taken back samples of moon in the previous moon landings.
