Can humans should be sent to other planets after 50 years yes/no reasons.?
Are you asking “can humans be sent to other planets”, or are you asking “should humans be sent to other planets”? Two different questions, but your wording isn’t clear which you are asking. And I’m not sure what “after 50 years” refers to. Can humans be sent to other planets? The technology to travel to other planets exists (Venus Express, Messenger, Mars orbiters and rovers, Cassini, etc.) but that technology isn’t advanced enough yet to support human life for trips to other planets. So for now, the answer is no. Should humans be sent to other planets? Certainly – the desire to search and explore has always been part of the human psyche. And there really is no other way to find life on other worlds – robots are fine for many things, but finding life will probably be done by humans.
