This week on Catch Our Drift, we are exploring the parallel realms of Outer Space and Inner Space as we gaze at the stars and also turn our eyes downwards to contemplate the vast ocean depths.

We’re delighted to be joined by astronaut and aquanaut Kathy Sullivan – the only woman to have walked both in space and descend to the ocean’s greatest depth.  Who better to tell us about both worlds?   Fabien Cousteau shares his plans to build Proteus, the ocean’s equivalent of the International Space Station, an underwater habitat that will enable aquanauts to live on the seabed for weeks at a time.  And ice cream seller turned oceanographer Craig Donlon discusses his work at the European Space Station monitoring the impacts of climate change on our ocean from space.
