During a Q&A held at the SXSW festival in Austin, Texas on Sunday, SpaceX founder Elon Musk discussed the future of his space faring business, and in particular, his plans for a fleet of interplanetary ships with a course set for Mars. Of course, the man hailed by many as a visionary, wanted to be sure to temper the enthusiasm of those already packing their bags.

“It’s difficult, dangerous, [there’s a] good chance you will die,” he explained about those who would first set foot on the Red Planet. “Excitement for those who survive, that kind of thing.”

“I think there aren’t that many people that want to go in the beginning because all those things I said are true. But there will be some who will, for whom the excitement of frontier and exploration exceeds the danger,” he added.

The rocket that will ferry SpaceX crews or passengers to Mars, the Big Falcon Rocket (BFR) is actually already under construction, and promises to usurp the Falcon Heavy as the most powerful rocket in the SpaceX arsenal. In fact, it will likely be the most powerful rocket in use anywhere on the planet (a title currently held by the Falcon Heavy) depending on whether or not NASA has been able to field the SLS by that time, as well as how the final stats for the new platforms match up.
