What are the long term effects of space travel on the human body? With an eye on Mars, that’s what NASA set out to reveal in it’s "Twins Study" Human Research Program.

The preliminary results packed a few surprises. Famed futurist and theoretical physicist, Dr. Michio Kaku, talks with Kennedy on FOX Business about the study’s most remarkable findings. WATCH NOW!
