Futureproof Gold: Astronaut Gregory H. Johnson
Becoming an astronaut is hard. Not only does it require high levels of intelligence, determination, skill, and sacrifice, there is also an element of luck involved.
As a result, very few of us have or ever will have the privilege of going into space, and so speaking to those who made that journey is the closest we will ever get.
But, if you are fortunate enough to go just what is it like once you get there? Just what do the astronauts on the ISS do with their time and what can we learn from the experiments they conduct 408km above us?
Jonathan is joined by former astronaut, Gregory H. Johnson, pilot of two shuttle missions, and President & current Director of the Center for Advancement of Science in Space, to speak about the work that goes on in the ISS and just what it's like to come back to Earth after so long spent in zero gravity.
