These exploratory spacecraft are inexpensive. Only 10% of the NASA budget is spent on what does all the science - unmanned spacecraft. The 90% spent on manned programs has yet to be doing any useful science. $80billion on a space station that was only supposed to cost $8billion - and it still has never done any useful science.
Many of the research from Venus and Mars have resulted in insights into how our own world works and how we can screw it up. If concerned for protecting this planet, then unmanned missions to other solar system bodies are essential research.
