I just started thinking about it. Why is space exploration even that necessary? They're spending so much money on it when we have so much problems in our own planet..
Not really, it's more like a childhood dream that nobody investing will see IF it will give any results and/or is just a over expensive hobby, for the sake of have the knowledge of guessing of what is the planet that is over 5000 years light away from us might be made of. Who knows! It might have some form of H2O!
