i think yes, and here's the reason
sending a man is not a problem, getting him back is headache
if some people agree to one way ticket then we can reduce net cost by 80%
slowly these one way people will develop a small society there and in future more
people will be sent to make it further evolve
by 2020 we can think of it and plan for it in a grand manner
when it'll become fully sustainable in and around 2050 we might have our holiday trip to mars.
it is possible because mars's soil has all nutrients to grow trees and we can use artificial uv light to imitate suns light.
this will provide them food and air both.
a great idea do encourage.
