Spacecraft engineer Dr. Leah Alconcel joins Dr. Anna to tell her about the one item she can’t live without - her lasers
From sending spacecraft to Saturn to the possibility of being able to watch TikTok in outer space, Dr. Leah shares the critical role that lasers have in her life. We are joined again by Rio’s Chief Scientist, Nigel Steward, who reveals how lasers are in fact a fundamental part of everyone’s daily lives and the role of the very small but powerful metals called Rare Earths which ironically (and thankfully) are not that rare.

Another exploration expert - Rio Tinto’s Managing Director of Studies, Alison Morley - joins us to share tales of following the clues found in the patterns in rocks and what these patterns tell us about our earth, before Dr. Anna asks both Dr. Rosa and Alison how we can ensure that these ecosystems being explored are protected for our future.
