SpaceX CEO Elon Musk said there's a "70 percent chance" he'll personally travel to Mars. Musk told Axios that he believes Mars exploration is more than just a fantasy dreamed up by the super-wealthy who may want to use space travel as an "escape hatch." He also added that the risks of space travel are real, and there is a high-probability of death, even if you land safely. Still, he said he would not hesitate to travel there.
