    Christina Koch: Artemis II, the ISS, and NASA’s Return to the Moon

    NASA astronaut Christina Koch represents a new era of human spaceflight. From her record-setting 328-day mission aboard the International Space Station to her historic role on Artemis II, Koch’s career connects the hard-earned lessons of long-duration spaceflight with NASA’s return to deep space. In this episode of Orbital Briefing, Ron Walker explores Christina Koch’s journey from engineer and remote field scientist to ISS flight engineer, spacewalker, and Artemis astronaut. We look at how her time in orbit helped prepare NASA for the future of lunar exploration, why her role on Artemis II matters, and how her story reflects the evolution of the modern astronaut. This is not just a biography. It is a look at how the Shuttle era, the International Space Station, and Artemis all connect through one remarkable career. We discuss: Christina Koch’s path to NASAHer 328-day mission aboard the International Space StationThe first all-woman spacewalksWhy long-duration spaceflight matters for Artemis and MarsHer role on Artemis IIHow NASA’s astronaut corps has evolved since ApolloWhy Koch represents the future of exploration This episode is sponsored by The American Spaceplane: A Story of Ambition, Risk, and Reinvention, Ron Walker’s book about the Space Shuttle program, available through RetroJet Studios.

    Apollo 13: NASA’s Near Disaster, Moon Mission Crisis, and Safe Return to Earth

    What really happened on Apollo 13? In this episode of Orbital Briefing, Ron Walker tells the full story of NASA’s most famous in-flight emergency, from the launch of the Moon mission to the oxygen tank explosion, the aborted lunar landing, the use of the Aquarius lunar module as a lifeboat, and the dramatic safe return to Earth. This deep dive explores the Apollo 13 crew, Mission Control in Houston, the carbon dioxide crisis, the power-down of the command module, the swing around the Moon, and the tense reentry that turned a failed lunar landing into one of NASA’s greatest survival stories. If you’re interested in Apollo program history, NASA missions, space exploration, Moon landing missions, and the true story behind Apollo 13, this episode is for you.

    Mission Control: How NASA Flies Spacecraft from Earth | Inside Houston’s Nerve Center

    How does NASA actually fly a spacecraft once it leaves Earth? In this episode of Orbital Briefing, Ron Walker takes you inside Mission Control, the nerve center of American human spaceflight. From Gemini and Apollo to the Space Shuttle, the International Space Station, and Artemis, Mission Control has been where flight controllers monitor spacecraft, guide astronauts, solve problems in real time, and make the decisions that keep missions alive. This episode explores how NASA built one of the most important operational systems in space history, and why Mission Control remains just as essential today as it was during the Moon race.

    Sputnik The Tiny Satellite That Started the Space Age

    Sputnik: The Beginning of the Space Age takes you back to October 4, 1957, when Sputnik 1, the first artificial satellite, launched from the Soviet Union and changed history forever. In this episode of Orbital Briefing, Ron Walker explores the story of Sputnik, the start of the Space Age, the rise of the Space Race, and the moment the Cold War moved into orbit. Learn how Sputnik 1 shocked the United States, triggered fears about Soviet rocket technology, reshaped NASA history, and helped launch a new era of space exploration, satellite technology, and spaceflight history. From the famous Sputnik beep to the political panic it created, this episode covers the origins of the U.S. vs. Soviet Union space race, the meaning of the first satellite launch, and why Sputnik remains one of the most important milestones in space history. If you love NASA, space history, Cold War history, rocket history, satellites, Apollo, and the origins of modern space exploration, this episode is for you. Sponsored by RetroJet Studios.

  8. The Space Shuttle Heat Shield: How NASA Survived Reentry from Orbit

    MAR 26

    The Space Shuttle Heat Shield: How NASA Survived Reentry from Orbit

    How did the Space Shuttle survive the most dangerous part of every mission? During reentry, the shuttle slammed into Earth’s atmosphere at over seventeen thousand miles per hour. Temperatures outside the spacecraft soared into the thousands of degrees, hot enough to melt the aluminum structure of the orbiter in seconds. The only thing standing between the astronauts and that inferno was one of the most remarkable engineering systems NASA ever built: the Space Shuttle’s thermal protection system. In this episode of Orbital Briefing, we take a deep dive into the technology that made reusable spaceflight possible. From fragile silica tiles to reinforced carbon-carbon panels on the wing leading edges, we explore how NASA designed a spacecraft that could survive reentry again and again. We’ll also look at the thousands of engineers and technicians who maintained the shuttle’s heat shield between missions, the early challenges of the first shuttle flights, and the lessons learned after the tragic loss of Columbia in two thousand three. The shuttle didn’t just go to space. It had to come home through fire. And the heat shield made that possible.
