Elon Musk is nothing if not ambitious, especially when it comes to the future of space. At a startup festival in Hong Kong on Tuesday, the SpaceX CEO said that he’ll be announcing plans for a Mars-bound spacecraft later this year, and claimed that he plans to send humans to the planet within the next decade. According to him, colonizing Mars is essential for the continuity of the human race, and that confining ourselves to a single planet will result in our eventual extinction. Musk also announced that he himself will be taking a trip to space within the next five years.
