Last month, NASA announced the discovery of a seven-planet system called TRAPPIST-1, just 39 light-years from our Sun.  The Sky Guys will  discuss why this system might give hope for other habitable planets beyond our solar system.  And SpaceX announces that two people have already put down a deposit for a trip to the moon and back in 2018.  Plus a look at NASA's research into the effects of space travel on humans, and how you can join the search for Planet 9.
