What are the advantages and disadvantages of space research...

Actually by space reasesch human can know many things like Increase human knowledge of nature's processes using the space environment, Explore and settle the Solar System, Achieve routine space travel, Enrich life on Earth through people living and working in space. and i think there is no disadvantage of this space research

this issue is one which is quite divisive among people, there are those who say we should put money into getting rid of poverty and there are those who say put it into space research, for me space research is a vital thing at the moment in these times of worry about global warming etc. If we look at the writings of people like greg bear, we see that he warns us that this sort of research has to be done in order that if the end comes and we have completely destroyed our planet, we have to have somewhere to go, but the problem is that if we find somewhere else to go, we should not damage our new home, so space research has great benefits for the future of mankind, not only will it allow us to look for a new home, but it will also allow us to look back in history and see what will happen if we do not look after the planet we are on at the moment.
