Space Exploration expensive

The thrill of discovery interest(gr. ) a lot of people and this is the main reason of (ww. - for) exploring the space and other planets. However, this is not the only reason to explore the space. There are a lot of problems on Earth that force people to explore other planets. However, People think that space exploring(ww. - exploration) has some risks and (is) too expensive.

On the one hand, the discovery of other planets is very important in order to live on them when the eath(sp.) will be gone. There is also the ambition of finding other living forms in space that might help us in the problems on Earth or to learn about them. There are also(phr. - In addition there are) satellites that improve the life on Earth while they transmission(ww. - transmit) programs on T.V and the radio.

On the other hand, space exploration has a lot of risks to other people that want to be launched to the space(you have to explain what you mean what kind of risks and why you mention: "to other people"? who are these "other people"?). (Moreover,)The launch to space costs a lot of money, building the spaceship, the planning of the flying in the space etc. Once in a while when a satellite is launched to the(מיותר) space, it might hit other things in space like stones in space(ww. - debris or meteors) or other satellites and create a massive mess in space that can hurt us or other things(This is too general, what "things" are you talking about?).

To sum up, both of the ways (which "ways" are you talking about?) injure(ww. - hurt) us , the(מיותר) space exploration has a lot of risks and spends a lot of money but help(gr.) us discover things that might help us in the future. My personal opinion is that we should continue space exploration in order to find helpful things for humanity.

It's better, but you still have quite a few mistakes to correct and sentences to rephrase and explain better. (75)
