Astronauts sometimes feel lonely in outer space. A friendly robot called CIMON 2 can help solve this problem. It arrived at the International Space Station (ISS) on Dec 9. With a screen for a face and two cameras for eyes, the robot can “talk” with astronauts. CIMON 2 can not only understand what people are saying, but also evaluate (评估) their emotions (情感) and give an appropriate (合适的) reply. It will stay with the astronauts for three years.
