When the Russian crew on board the ISS decided to perform an unusual procedure on the station’s Zvezda module, it caused quite an agreeable break in the routine of the day on board the orbiting laboratory. The crew on the US segment entered an emergency evacuation posture aboard their Crew Dragon, but all returned to normal after a few hours. The team discusses what happened and why.

The astronauts for the Artemis III mission were introduced to the world at NASA’s Johnson Space Center in Houston, TX, with much fanfare and some controversy: No female astronauts were named to the crew. Was this just a normal crew rotation, or was politics at play? The panel looks at the points of contention and weighs in on the Artemis III mission itself.

NASA’s X59 Quesst aircraft, built by Lockheed Martin, is an incredible experiment aimed at reducing a sonic boom to a barely audible thump. If successful, the project has far-reaching implications for the future of civil aviation. Our Mark Ratterman reports on this unique aircraft's first flight tests and its implications.

SpaceX launched something its CEO, Elon Musk, said he would never do: turn SpaceX into a public company and, in the process, turn Musk into the world’s first trillionaire. Heather Smith has been watching this story for us for a while now and delivers some insight into what happens next.

On the heels of the SpaceX IPO, environmental groups in and around Cameron County, Texas, are fighting a plan by the US Fish and Wildlife Service to reallocate land inside the Lower Rio Grande Valley National Wildlife Refuge to SpaceX to support Starship Operations.

The Talking Space Team gathers around the microphone once again to survey the horizon of spaceflight news—and what an eventful week it has been.

On May 26th, NASA announced a new wave of contracts for its moon base program, along with updates on the progress of Artemis III. We break down exactly what was said during the press event and what it means for humanity's return to the lunar surface.

SpaceX launched its highly anticipated Starship 12 mission on May 22nd, showcasing the brand-new Starship V3 vehicle. While some space news outlets were quick to stamp it as an unqualified success, the actual results were decidedly mixed. As far as debuts go, there is plenty of room for both applause and concern—and we dive deep into the launch.

The biggest, most shocking news of the week took place at Cape Canaveral Space Force Station in Florida. On Thursday, May 28th, a Blue Origin New Glenn rocket suffered a catastrophic explosion on Launch Complex 36, yielding the most powerful rocket explosion since the Soviet N1 moon rocket disintegrated in the late 1960s. This static-test accident sent shockwaves through both Blue Origin and NASA’s Artemis timeline. We attempt to begin picking up the pieces.

Decades ago, NASA's twin Pioneer spacecraft became some of the first human-made objects to chart a course out of the solar system. But as they crossed into deep space, a mystery emerged: both probes were mysteriously slowing down. The effect was later referred to as the Pioneer Anomaly. With assistance from the Planetary Society archives, our resident cosmic detective, Mark Ratterman, goes on the case to solve this historic deep-space puzzle.

The full Talking Space team gathers around the microphone once more to share their thoughts and reactions to the Artemis II lunar flyby and how the 10-day mission was perceived back on Earth, especially those who seldom think about NASA. The panel examines next steps for the Artemis program, reviews highlights from NASA’s recent Ignition event, weighs whether a new space race with China is underway, and considers what the future may hold given the implications of the 2027 NASA Budget.

Australia has the capabilities to be a major space sector player, but lacks a cohesive national space policy. Isobel Haddow of The Space Industry Association and our resident space-policy expert, Dr. Kat Robison, crafted a brief for the United States Studies Center outlining the situation and what practical steps Australia can take. Dr. Robison discusses the highlights of her work and the panel debates the ramifications.
