Accurate Title But
You once again avoided what is obvious to most people. In short:
In addition to ignoring the mutual benefit aspect of Mars exploration technology and impact prevention, you also continue to ignore or fail to understand comments on political will not Mars funding being the primary obstacle to funding better detection systems. Australia's science minister dismissed the issue itself. He did not claim he would prefer to spend the money on Mars missions.
The conflict between Mars exploration and impact prevention is a figment of your imagination.
