From Earth orbit to the Moon and Mars, explore the world of human spaceflight with NASA each week on the official podcast of the Johnson Space Center in Houston, Texas. Listen to in-depth conversations with the astronauts, scientists and engineers who make it possible.

On episode 400, acting NASA Administrator Sean Duffy joins us for our milestone 400th episode to share his journey and vision for advancing NASA into the future. This episode was recorded August 18, 2025.

NASA's Zero Gravity Research Facility - A steel vacuum chamber 50 stories deep at NASA’s Glenn Research Center lets researchers simulate near-weightlessness by letting test hardware freefall for 5.18 seconds.

Predecir la meteorología espacial es fundamental para el regreso de los seres humanos a la Luna con la campaña Artemis. Comprender la radiación solar y desarrollar sistemas de protección no es solo una cuestión de descubrimiento científico: es esencial para la seguridad de los astronautas más allá de la magnetósfera protectora de la Tierra. Y, en última instancia, para el éxito de nuestros ambiciosos planes de establecer una presencia sostenible en la Luna y, más adelante, en Marte.

On episode 399, NASA astronaut Suni Williams reflects on her record-breaking mission, her perspective after returning to Earth, and her journey as one of the most experienced spacewalkers in history.

On episode 398, Chris Edelen, acting vehicle integration office manager for NASA’s Orion Program, discusses the spacecraft that will carry astronauts around the Moon on Artemis II.

From black holes to star clusters, NASA is turning space data into audible sounds with a process called sonification. Dr. Kimberly Arcand, visual scientist with the Harvard-Smithsonian Center for Astrophysics, joins us to explore how data sonification lets more people experience the cosmos and give researchers a new way to interpret science one note at a time.

Houston We Have a Podcast: The Art of Astronaut Photography by NASA

On episode 396, NASA project scientists Maria Banks and Sue Lederer revisit recent Commercial Lunar Payload Services missions and discuss research on the Moon.

NASA’s StarBurst mission, a satellite about the size of a washing machine, is set to launch in 2027 to detect the initial blasts of these cosmic fireworks. By studying gamma-ray bursts in unprecedented detail, StarBurst will help scientists probe the extreme physics of neutron star collisions and shed light on one of the most powerful events in astrophysics. We’re talking about it today with Dr. Dan Kocevski, principal investigator for StarBurst, out of NASA’s Marshall Space Flight Center in Huntsville, Alabama.

Desde su órbita alrededor de nuestro planeta, el telescopio espacial Hubble de la NASA ha sido un ojo incansable que mira hacia lo más profundo de nuestro universo desde hace más de tres décadas. Sus hallazgos no solo han revolucionado nuestra comprensión del cosmos; también nos han acercado a él de manera íntima. La astrofísica Rosa Díaz nos acompaña en un recorrido de esta misión emblemática desde el Centro de Control de Operaciones de Hubble.
