For most Americans, the story of the Hubble Space Telescope began on April 24th, 1990, the launch date of the now 30 year-old observatory. But for astronaut Kathryn Sullivan, Hubble’s journey began on a wintery day in early 1985 at a meeting at NASA headquarters, where she was assigned to the mission that would take Hubble into space. For the next five years, Sullivan, a former oceanographer and first female spacewalker, got to know Hubble intimately, training and preparing for its deployment. If Hubble’s automatic processes failed as it was detaching and unfolding from the spacecraft, Sullivan would be the one to step in and help. And she almost had to. Sullivan joins Ira to share the untold stories of Hubble’s launch and her time at NASA as told in her new book Handprints on Hubble. Physicist Marie Curie is remembered as the first woman to win a Nobel Prize, and the first person—of two ever in history—to win two Nobel Prizes. With her role in discovering radium and polonium, and the energy emitted in the decay of large atomic nuclei, she brought us the concepts of radiation and radioactivity. Curie helped lay the groundwork for a revolution in both physics and chemistry. But a new play explores the person behind the brilliant scientist. In The Half-Life Of Marie Curie, we meet Curie after a scandal: She’s been caught having a love affair with a married man. But in a time of depression and isolation, she’s rescued by a friend, English scientist Hertha Ayrton—also an intrepid but lesser-known physicist, engineer, and suffragette. Playwright Lauren Gunderson joins Ira to talk about the deep friendship between the two scientists, the importance of seeing Marie Curie as a person outside her work, and the many connections between storytelling and science.
