Zephram cochran (star trek lol)sorry could not pass that up..no person has made it to mars yet....I think it would take a lifetime to go and come back with the craft we have now and then you have the food /oxygen not to mention other little things to plan for like the space suit to handle the atmosphere if they truly wanted to be the first human on mars...the others already gave the answer for thew moon question....
The first person to reach moon is Neil Armstrong.
I believe the U.S. Was first to land probes on Mars, but no human has set foot on Mars.
Not one person has been on mars as there have been no manned missions there as of yet, and the U.S. Was the first country on the moon and Niel Armstrong was the first man to set foot on the moon. Hope this helps, good luck to you.
