As the UK's largest Antarctic base, Rothera Research Station, celebrates its 50th birthday, host Nadia Frontier assembles a portrait of Rothera past and present. This episode features four fascinating perspectives on heritage, community and the importance of change.

Alysa Fisher offers an archivist's account of the station's early years - from the wartime beginnings of the UK's Antarctic presence, to the highly popular dogs who used to live at the station, as well as what bits of history can be found embedded into modern station life.

Outgoing Head of the BAS Air Unit, Rod Arnold, talks about how the people and the place have evolved across his 26 years of service; current Tower Supervisor Matt Hughes chats about the aircraft (and whales) he's seen from the new Operations Tower; and Station Leader Aurelia Reichardt talks science operations, leadership, and what it takes to keep a community going in this frozen wilderness.
