PRESENTATION: SHOULD WE GO TO MARS? – THE BIG THINK
2019 will be the 50th anniversary of the first moon landing. It was the greatest technological achievement of the 20th century. Since then, Nasa’s goal has been to send an astronaut to Mars. But it’s proving far harder than anyone imagined.
Some experts believe that human space travel and exploration is critical. But Mars is over 200 million kilometres away, and the effort to land a human on our closest planet risks billions of dollars and the lives of those brave enough to try. Is the possible benefit worth the risk? And is it really achievable?
Guiding us through this ethical and scientific minefield is Dr Kevin Fong. Kevin's diverse background in astrophysics, aeronautics and medicine makes him uniquely placed to understand the technical and human challenges of this perilous journey. With the help of the BBC's rich archive and a cast of supporting experts, Kevin leads us through the journey to Mars stage by stage.
For Kevin, not only is this the toughest journey we will ever attempt, it is one that he feels we ultimately must make if we are to survive as a species.
