B Discussion 1
I agree with the author’s opinion. The exploration of space has brought us technologies that we use in our everyday lives.
I do not agree with the author’s opinion, because the focus should be on developing technology to keep the Earth and all its inhabitants safe and healthy.
C Discussion 2
The future of space exploration will expand our understanding of our role as humans. As space exploration reveals more mysteries, our perspective of our 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 better understand the importance of working together to solve other problems on the Earth, such as poverty, hunger and war.
