Dr. Padi Boyd, a NASA astrophysicist and co-host of "Curious Universe," joins fellow expert Dr. Ingrid Daubar, a planetary scientist at Brown University, to discuss the launch of the Europa Clipper. They delve into the mission's groundbreaking goal to explore Europa's icy surface for potential signs of life beneath its crust. The duo shares insights on the spacecraft's innovative instruments and nearly 50 planned flybys. With excitement brewing for upcoming discoveries, they reflect on the importance of studying this mysterious moon in the search for extraterrestrial worlds.
NASA's Europa Clipper mission, equipped with ten scientific instruments, aims to investigate the icy moon's potential for supporting life by analyzing its surface and subsurface ocean.
The inclusion of a poem by U.S. Poet Laureate Ada Limon in the Europa Clipper mission symbolizes the intersection of art and science in humanity's quest for knowledge beyond Earth.

Launch of Europa Clipper
Europa Clipper was successfully launched on October 14, 2024, after a short delay due to hurricane conditions in Florida. The launch gathered significant attention, creating a blend of excitement and anxiety among the team members, who had dedicated over a decade preparing for this moment. Dr. Patti Boyd described the atmosphere at NASA, highlighting that the launch was an emotionally charged experience, with everyone focused on the screens, hoping for a successful lift-off. The remarkable event reinforced the importance of precision in space missions as they celebrated the successful deployment of the spacecraft on its journey to explore Europa.
Scientific Instruments and Objectives
Europa Clipper carries ten scientific instruments aimed at investigating Europa's potential for habitability. The suite includes cameras that operate across various wavelengths, as well as in situ instruments that will sample the icy moon's environment. This ambitious mission will allow scientists to analyze surface composition, geology, and the subsurface ocean potential, specifically looking for signs of past or present life. By conducting close flybys at speeds reaching 10,000 miles per hour, the spacecraft will gather critical data, which was previously unattainable.
Human Touch in Space Exploration
One unique aspect of the Europa Clipper mission is the inclusion of a poem by U.S. Poet Laureate Ada Limon, intended to encapsulate humanity's quest for knowledge and connection with the cosmos. This tradition of sending a 'message in a bottle' reflects the ongoing human narrative in scientific pursuits, emphasizing the significance of exploration and the search for life beyond Earth. The poem resonates with the mission's objectives and serves as a reminder of the deeper motivations behind such scientific endeavors. By merging art and science, this inclusion highlights the human element in our remote explorations throughout the solar system.
On October 14, NASA launched Europa Clipper, its largest planetary mission spacecraft yet. It’s headed to Jupiter’s icy moon Europa, which could have a giant ocean of liquid water hidden under its icy crust. And where there’s water, scientists think there may be evidence of life. The spacecraft is equipped with nine different instruments and will complete nearly 50 flybys of Europa, scanning almost the entire moon.
SciFri producer Kathleen Davis talks with Dr. Padi Boyd, NASA astrophysicist and host of the agency’s podcast “Curious Universe,” about the launch and the excitement at NASA. Then, Ira checks in with two scientists who are working on the mission about what they’re excited to learn: Dr. Ingrid Daubar, planetary scientist at Brown University and a Europa Clipper project staff scientist at NASA’s Jet Propulsion Laboratory; and Dr. Tracy Becker, planetary scientist at Southwest Research Institute and a deputy principal investigator for the ultraviolet spectrograph on the Europa spacecraft.
