Space is important because if in the future anything happened to our plant (earth) and it is no longer there, where will we go? There are over 7 billion humans on earth which is a lot, we are all in the same world and crammed in to one planet. Eventually there will be more humans and less space for us all!
Space also provides earth with valuable metals, rare objects and precious materials that can be used for medical research. These special things can help cure diseases and help us to survive. Space is playing a valuable role in saving lives.
If NASA stopped exploring our universe, we would not know important facts about space and our solar system. Without exploring and developing space programmes how will we continue to evolve? There'd be no accurate weather reports and no valuable experiments that can't be done on earth. If NASA stopped the work they do in space, humans would eventually be extinct.
Astronauts are already exploring space and learning more about it, they are giving us the opportunity to discover new worlds. Astronaut's jobs are important, if they stopped finding out about space this would mean we would not learn new special facts about the planets we already know about.
If meteors hit our planet astronauts would warn us in advance so that we’d be prepared for the meteor attack. If the astronauts stopped the exploration of space, the impact of meteors would damage the earth and harm the environment.
I think space is very important to our existence and I'm excited to find out what more space can offer us. Aren't you?
