Artemis II Crew Runs Through Full Launch Day Simulation

On December 20, 2025, the four astronauts of NASA’s Artemis II mission participated in a comprehensive launch day dress rehearsal at Kennedy Space Center in Florida. The simulation covered the full sequence of activities astronauts would experience on actual launch day—from suiting up in their spacesuits to boarding the Orion spacecraft. The countdown proceeded smoothly but was halted just before ignition, as is standard during such dry runs. Among the crew was Canadian Space Agency astronaut Jeremy Hansen, who continues to represent Canada on this historic mission that will send humans around the Moon for the first time since Apollo 17 in 1972. These rehearsals are critical for identifying procedural hiccups and ensuring seamless coordination between astronauts, ground support, and mission control. With the actual launch still on the horizon—currently targeted for no earlier than September 2026—this drill marks a significant milestone in the final phases of preparation. It also offers a rare glimpse into the choreographed precision required to launch humans beyond low Earth orbit.

NASA Welcomes Jared Isaacman as New Administrator

One day after being sworn in, Jared Isaacman held his first official engagement with NASA employees on December 20, 2025, in a virtual Town Hall meeting. Isaacman, known for commanding the all-civilian Inspiration4 and Polaris Dawn missions, is the first commercial astronaut to lead the U.S. space agency. During the session, he emphasized continuity in ongoing programs—including Artemis—while hinting at a renewed focus on operational efficiency and public-private partnerships. He also acknowledged the political context of his appointment but kept the conversation centered on NASA’s mission and workforce. Isaacman’s background as both a pilot and entrepreneur brings a unique perspective to the role, and his hands-on experience with recent private spaceflights could influence how NASA approaches future collaborations with companies like SpaceX and Blue Origin. Employees appeared cautiously optimistic, with many noting his familiarity with modern launch systems and risk management. Though his tenure is just beginning, his early message is clear: NASA will keep its eyes on the Moon and Mars while streamlining how it gets there.

Blue Origin Sends First Wheelchair User to Space

In a milestone for accessibility in spaceflight, Blue Origin’s New Shepard vehicle carried Michi Benthaus—the first known wheelchair user—to space on December 20, 2025. Benthaus, who sustained a spinal cord injury during a mountain biking accident in 2018, flew as part of the NS-37 mission, which included five other passengers on a brief suborbital journey. The flight reached an apogee of approximately 105 kilometers, providing several minutes of weightlessness before returning to Earth under parachutes. Blue Origin worked closely with Benthaus and accessibility experts to modify seating and ingress procedures, demonstrating that space tourism can—and should—be inclusive. Her journey is more than symbolic; it challenges long-standing assumptions about who can participate in space exploration. As Benthaus noted post-flight, “Space belongs to everyone.” With commercial spaceflight maturing, such flights underscore a broader shift toward democratizing access to space, not just for the ultra-wealthy or traditionally trained astronauts, but for people of diverse physical abilities. This mission may well set a precedent for future inclusive design across the industry.
