If you have one hour if front of you, I highly recommend this documentary: <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=tcTZvNLL0-w" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=tcTZvNLL0-w</a><p>In it they explain how it would be feasible to be on Mars in ten years with current technology and not so much additional fundings.
