Duration: 1 hour

In the fourth episode of this new six-part science series, Dara O Briain and his crack team of experts take a peek into man's final frontier - space.

Science journalist Alok Jha asks whether it is a good idea for humans to reach out to extra-terrestrials and oceanographer Helen Czerski comes face to face with extreme radiation, energy so deadly it could seriously curtail humans travelling further than the solar system. Plus special guest Josh Widdecombe visits NASA in Houston to find out the challenges we face to get humans to Mars and materials scientist Mark Miodownik takes apart a space suit.

Combining lively and in-depth studio discussion, with exploratory films and on-the-spot reports, Dara O Briain's Science Club takes a single subject each week and examines it from lots of different and unexpected angles from sex to extinction, Einstein to space exploration and brain chemistry to music. It brings some of the world's foremost thinkers together to share their ideas on everything, from how to avoid asteroid impact to whether or not we are still evolving.
