SpaceX CEO says he believes he'll send people to Mars by 2026, or even 2024.

Iran PressAmerica: This timeline has Musk taking off for Mars when NASA just might be reaching the moon again. 

We can't ignore the countless unanswered questions about Mars travel and habitation.

SpaceX CEO Elon Musk remains "highly confident" that his company will land humans on Mars by 2026, saying on Tuesday that it’s an achievable goal "about six years from now."

"If we get lucky, maybe four years," Musk said, speaking on an award show webcast from Berlin, Germany. "We want to send an uncrewed vehicle there in two years."

The ambitious 2026 goal matches with what Musk outlined at the International Astronautical Congress in September 2016, when he said that "if things go super well," landing people on Mars "might be kind of in the 10-year timeframe."
