Machines to Mars

Going to Mars has long been mused.
Humans have always had the itch
To explore, and some be enthused
To make a hike to Mars and hitch,
Of course spending other's money -
N.A.S.A. is well practiced at that,
Notwithstanding that humans be
Messing up all Earth's habitat.
Make humans clean up the mess here,
And send machines to Mars if must.
Machines don't need life atmosphere,
And do a better job to trust.

Going to Mars should be machine.
Humans will just mess up the scene.
