The PLATO mission: Discovering other planets fit for life - with Ana Heras and Alistair Winton
Summary
This episode explores the European Space Agency's PLATO mission, designed to detect terrestrial exoplanets in the habitable zones of sun-like stars using the transit method. Guests Anna Heras and Alistair Winton discuss the spacecraft's 26 cameras, which capture 2 billion pixel images to identify subtle dips in starlight. They explain how PLATO will determine stellar ages via asteroseismology and characterize planet masses through ground-based follow-up. The episode also details the successful completion of electrical testing in a Faraday cage at ESTEC, confirming the spacecraft is ready fo…
