The question of exploring space has been discussed from the very beginning of space exploration. Some people say that it is our future, whereas others are quite skeptical.

I think that we should definitely explore space and spend as much money as required. First of all, our planet cannot exist forever. One day it will end and humans will have to move somewhere to continue living. Second, underground resources are finite and they will eventually end. It would be nice to have a possibility to import raw materials from other planets. It is also very interesting to meet other civilizations, if they exist.

At the same time, there are people who think that exploring space is a big waste of time and money. Every space shot costs us a lot of money. It is better to do something on earth that can be useful here and now.

In my opinion, it is not really a good forward-looking policy. It is better to be prepared for possible troubles that can come faster than we think. Global Warming can submerge the entire planet or a comet can hit the earth. I think people should be ready for any possible danger.

In conclusion, I would like to say it is difficult to keep doing space exploration when our national economic situation is not that good. Nevertheless, we should keep investing into space exploration because I strongly believe that one day it will bring the desired results. Thus, I support the idea that space exploration is worth doing.

In conclusion, I would like to say there are opposing views on this issue. At first sight space exploration is a big waste of time and money but in actual fact it can bring a lot of benefit to people. Thus, I strongly believe that exploring space is worth doing.
