but probes have a lot of limits: they can only travel very small distances at a time, they cant bring back samples, they need to be controlled from earth, they cant think for themselves, etc....
then agian us humans also have limits: we need an air supply, we need food and water, and enough fuel has too be brought to get us back to earth, etc....
but we are less dependent on control from earth, we can make our own decisions, and we are great problem solvers.
i agree that the scientists and engineers involved in the construction and operation of those little robots deserve our recognition, and that some amazing things have been discovered.
but we havent actually been to any of these amazing places.
and i dont think you can justify not going by saying theres a risk. every form of transport has risks, and if we were worried about the risks of space travel we would have abondoned the ISS long ago.
