Stop faffing around sending probes to planets like Mercury and start properly planning on getting humans on Mars. I know it's hard, it's quite probably as hard as rocket science but that's no excuse for preferring to send 'easier' pilotless probes to various places around the solar system.
You're all dead clever and quite able to to a manned mission to Mars so stop gassing about the complexities of it or pooh poohing everyone else's attempts (like Mars One) and get on with it!
People my age want to see someone put a foot on Mars in our lifetime ffs!!
Or perhaps even the moon!
