Ever since Elon Musk founded a start-up space company 14 years ago, the goal has always been the same: Establishing a colony on Mars. Now he’s finally beginning to reveal how he plans to get there.

Starting as soon as 2018, Musk’s SpaceX plans to fly an unmanned spacecraft to Mars. The unmanned flights would continue about every two years, timed for when Earth and Mars are closest in orbit, and, if everything goes according to plan, build toward the first human mission to Mars with the goal of landing in 2025, Musk has said.

But in an interview with The Post this week, Musk laid out additional details for the first time, equating the spirit of the missions with the settlement of the New World by the colonists who crossed the Atlantic Ocean centuries ago. And he acknowledged the immense difficulties of getting to a planet that is, on average, 140 million miles from Earth.

The months-long journey is sure to be “hard, risky, dangerous, difficult,” Musk said, but he was confident people would sign up to go because “just as with the establishment of the English colonies, there are people who love that. They want to be the pioneers.”
