A NASA advisor is taking billionaire Elon Musk’s Mars plans to task, writing Thursday that the highly ambitious endeavor won’t happen “anytime soon.”
Musk, the founder of SpaceX, has repeatedly stated that getting humans to Mars is his end goal. Speaking on Fox News this week, he predicted that a multi-planetary civilization could come as soon as the next 20 to 30 years. Previously, he had predicted that an uncrewed landing on the red planet could happen as soon as 2026, with humans there before 2030.
