HMS Challenger was built in 1858 as a pearl-class wooden hold Corvette. It's armed before they take it with 22 guns, of which they take all but two off. And then they replace on the main deck a series of cabins that will become laboratories. They build all of these accommodations to take a very small scientific staff of about six.
Melvyn Bragg and guests discuss the voyage of HMS Challenger which set out from Portsmouth in 1872 with a mission a to explore the ocean depths around the world and search for new life. The scale of the enterprise was breath taking and, for its ambition, it has since been compared to the Apollo missions. The team onboard found thousands of new species, proved there was life on the deepest seabeds and plumbed the Mariana Trench five miles below the surface. Thanks to telegraphy and mailboats, its vast discoveries were shared around the world even while Challenger was at sea, and they are still being studied today, offering insights into the ever-changing oceans that cover so much of the globe and into the health of our planet.
