Summary (tl;dr)

The SpaceX Crew-12 mission is trending due to the recent removal of a Russian cosmonaut over alleged national security violations, while "next full moon" refers to the "Cold Moon" supermoon happening today, December 4, 2025.

Essential Background

SpaceX, under contract with NASA's Commercial Crew Program, regularly transports astronauts to the International Space Station (ISS) using its Crew Dragon spacecraft and Falcon 9 rockets. These missions are crucial for maintaining the ISS and conducting scientific research in orbit. Full moons occur roughly every 29.5 days when the side of the Moon facing Earth is fully illuminated by the Sun, with "supermoons" appearing slightly larger and brighter due to their closer proximity to Earth.

The Full Story

SpaceX's Crew-12 mission, planned for launch no earlier than February 15, 2026, is currently trending due to a significant crew change. Russian cosmonaut Oleg Artemyev was abruptly removed from the mission's prime crew on December 2, 2025. While Roscosmos officially stated his "transition to other work," investigative reports allege that Artemyev was expelled from the United States for violating International Traffic in Arms Regulations (ITAR) by photographing sensitive SpaceX technologies at their headquarters in Hawthorne, California. He has since been replaced by fellow Roscosmos cosmonaut Andrey Fedyaev.

Concurrently, the phrase "next full moon" is trending as the "Cold Moon," which is also a supermoon, will occur today, December 4, 2025, becoming officially full at 6:14 PM EST. This celestial event marks the last supermoon of 2025 and will appear notably high in the night sky.

Why It Matters

The Crew-12 incident highlights the complex geopolitical and security considerations inherent in international space cooperation, particularly concerning sensitive technologies and national security. The alleged ITAR violations could have significant implications for future collaborations between the U.S. and Russia in space. From a business and finance perspective, such disruptions can affect mission schedules and potentially lead to increased security protocols and costs for private space companies like SpaceX. On the science front, the regular cadence of crewed missions to the ISS is vital for ongoing scientific experiments and maintenance of the orbiting laboratory. Separately, the "Cold Moon" supermoon provides an engaging astronomical event for the public, drawing attention to space science and observation.
