Significant changes are underway at NASA. Cathy Koerner, associate administrator for exploration systems development, announced her retirement on Feb. 24, following the departure of Jim Free last week. Both departures have fueled speculation about the future of the Artemis lunar exploration program.

Koerner, who spent 34 years at NASA, held various key roles, including Orion program manager. Her departure, along with Free's, has raised concerns about the program's direction. "Cathy’s legacy is one of unwavering dedication to human spaceflight, and we are grateful for her years of service," said Janet Petro, acting NASA administrator, in a statement. The Trump administration’s reported scrutiny of Artemis adds to the uncertainty.

Lori Glaze, previously director of the agency’s planetary science division, will serve as acting associate administrator for exploration systems development. Vanessa Wyche, director of the Johnson Space Center, has taken over as acting associate administrator, succeeding Free. Petro stated, "Vanessa will bring exceptional leadership to NASA’s senior ranks, helping guide our workforce toward the opportunities that lie ahead."

In other news, NASA hired Jackie Jester as associate administrator for the Office of Legislative and Intergovernmental Affairs. Separately, NASA addressed a memo from the Office of Personnel Management requesting employee accomplishments. Initial conflicting advice to employees was later clarified: "NASA leadership is responding to the U.S. Office of Personnel Management (OPM) request on behalf of the agency workforce," an agency spokesperson said. "You are not required to respond, and there is no impact to your employment with the agency if you choose not to respond," Petro added.

Despite NASA's clarification, Elon Musk, reiterated threats to fire non-responsive employees. "Subject to the discretion of the President, they will be given another chance," he stated. The situation remains fluid.
