NASA astronaut Jessica Meir shares her childhood dream of becoming an astronaut and drawing herself on the moon.

This episode of Naked Astronomy, hosted by Richard Hollingham and Sue Nelson, features interviews with NASA astronaut Jessica Meir and ESA Senior Science Advisor Mark McCaughrean. The conversation covers Meir's career trajectory and the imminent launch of the James Webb Space Telescope. Jessica Meir recounts her childhood dream of becoming an astronaut, specifically drawing a picture of an astronaut on the moon in first grade. She made history by participating in the first all-women spacewalk from the International Space Station. Meir is now a crew member for NASA's Artemis program, which aims to return humans to the lunar surface. The James Webb Space Telescope is described as having a sunshield the size of a tennis court and a 6.5-meter primary mirror composed of 18 hexagonal, gold-coated segments. Mark McCaughrean has been involved with the Webb telescope project since before the Hubble Space Telescope's 1990 launch. He explains that initial concepts for a next-generation space telescope emerged even prior to Hubble's deployment. The telescope is currently at the European spaceport in Kourou, French Guiana, awaiting launch on an Ariane 5 rocket. A compelling insight is Meir's long-held, specific vision of herself as a lunar explorer, which she never abandoned. The technical scale of the Webb telescope, particularly its tennis-court-sized sunshield, is presented as a major engineering feat. McCaughrean's involvement highlights the decades-long international collaboration required for such a project. The episode frames the Artemis program as the potential fulfillment of a personal dream for Meir, who could be the first woman on the moon. The discussion connects a historic engineering milestone with the human narrative of a contemporary astronaut. The tone is conversational and educational, blending personal storytelling with clear explanations of complex space science. The style is interview-based, allowing the guests to share their direct experiences and expertise. Listeners interested in human spaceflight and the personal journeys of astronauts would find this episode engaging. Those seeking highly technical, physics-heavy astronomy discussions might find the content more introductory.
