Firstly, I believe that in we do and don't need the international space station, because I think it is great how we can do experiments in space, however it is costing an absolute fortune to keep running.
I think we do need it, because it is spectacular that we have the opportunity to even go up to space, but even better we can do experiments there. I believe this, because it is our duty to find out as much as we can about what can happen in space, also to look at other planets and figure out lots of facts about them. We can even find out facts about to maybe get be able to get humans to live ton Mars, but as you can tell that isn't happening any time soon. If we do carry on developing our facts and keep running the international space station, we would be able to achieve so much more and maybe complete our mission to Mars by aprox 2030 and maybe live on it.
I think we do not need the international space station, because it just costs way too much money, it can effect so much on our planet. We should spend this money on climate change and raising money for the NHS, because it cost $140,000,000,000 this amount could of helped everything. I think that we could resolve this problem of losing money, by trying new things that can be in orbit, like it is a great start using inflatables.
Therefore, I think that we don't and do need a thing that costs this much money, but can do great things.
