Elon Musk: I’d go to Mars only if I'm certain SpaceX will be fine without me.“I do personally want to step foot on Mars, but honestly, I’d be doing this even if I knew there was no chance of me going to Mars. I think it’s just important that we are on a path to getting there. I’d like to go at some point. I’ll go if I’m certain that SpaceX will be fine without me and that path will continue.You may have heard the joke I’ve made before, which is: I’d like to die on Mars. Just not on impact.”Sourc
