The time capsule was intended to be opened in 2000, but no one could remember where it was buried. When the capsule was finally discovered and dug up in 2013, it was amazing to see how times had changed.
学生：Another fascinating time capsule was launched to the International Space Station in October 2008. It contains a list of humanities most important achievements as well as personal messages from the earth.
