Choosing people or Spaceship

I believe that nations pay lots budgets put in spaceship for exploration the planets such as Moon or Mars or others. Do we really need to discover such things as spend lots money?

I disagree that because we need money to survive like our people who don,t have job or money to feed their kids and familes. Also I wander that the Doomsday is very near, so forget about the spaceship for now till things to get better!
