Elon Musk Predicts Manned Missions to Mars by 2029

On Twitter, Elon Musk gives Definitive Date for a Manned Mission to Mars

In a tweet early this afternoon, SpaceX founder Elon Musk predicted that human beings would land on the planet Mars by 2029.

Space Hub tweeted, "What's your guess? Referring to a photo of Neil Armstrong on the moon, above a photo of Mars with men walking on the red planet. "2029" tweeted Musk in reply.

Manned missions to Mars are much more difficult than trips to the moon. It is 100 times further from Earth, and would expose astronauts to cosmic radiation in potentially lethal doses. NASA has estimated the probability of a successful crewed round trip to Mars, at no more than 66%.
