As space exploration reveals more mysteries, our perspective of ou

41、r planet and ourselves will change. Past space exploration raised awareness of the need for global solutions to challenges. Furthermore, space exploration requires global cooperation, which is already practised on the International Space Station. Hopefully, future knowledge will help us understand the importance of working together to solve other problems on the Earth, such as poverty, hunger and war.
