The thirst of knowledge has been part of humans ever since we first evolved into intelligent creatures. The need to explore space arises from this thirst. It is why countries across the globe are finding new and novel ways to explore it. The objective might be practical or a more theoretical need that potentiality later, but the consequence is the same – getting to know the world beyond our world.
Two examples of the ground-breaking modes of space exploration are by China and the U.S.
Both these actions taken by the two countries show the two extreme sides of space exploration. While one helps the entire world to see a new side of the moon and opens up countless new possibilities for this and coming generation, the other can trigger a war. If one country (the U.S. in this case) can think to militarize space, then what stops other nations to do the same?
All in all, space is brand-new territory. Everyone is scrambling to mark it as their own!
