NASA has announced a comprehensive agencywide realignment to improve mission delivery speed and effectiveness in support of the National Space Policy. The restructure aims to streamline operations and concentrate resources on top priorities like the Artemis program and establishing a Moon Base.
New Organizational Structure
Key changes include direct reporting of mission directorates to NASA Administrator Jared Isaacman, enhancing focus on mission delivery and enabling faster resource coordination across centers, industry partners, and international collaborators. Center directors will continue reporting to Associate Administrator Amit Kshatriya, who now also serves as NASA’s chief engineer. This dual role reinforces NASA’s technical leadership and decision-making autonomy in engineering matters.
The realigned mission directorates are as follows:
- Human Spaceflight Mission Directorate (HSMD): This new directorate merges the Exploration Systems Development and Space Operations mission directorates, reflecting NASA’s operational presence in low Earth orbit and lunar exploration.
- Research and Technology Mission Directorate (RTMD): Combining Aeronautics Research and Space Technology directorates, RTMD will focus on research, space technology, aeronautics, and nuclear power and propulsion development.
- Science Mission Directorate (SMD): Remains unchanged, continuing its role in scientific discovery.
Leadership and Workforce Focus
The realignment also emphasizes rebuilding NASA’s core competencies by insourcing contractor roles to civil servants where appropriate and strengthening recruitment pipelines. The agency leverages its joint NASA Force initiative with the U.S. Office of Personnel Management to build a sustainable workforce equipped to meet future engineering and exploration challenges.
NASA Administrator Isaacman highlighted that the realignment promotes efficiency by removing bureaucratic obstacles without workforce reductions or program cancellations. The agency expects cost savings through more efficient mission execution and clearer mission focus.
Several leadership appointments accompany the restructure, including:
- Carlos García-Galán as program manager for Moon Base in the HSMD.
- Jamie Dunn as director of Goddard Space Flight Center.
- Brian Hughes as director of Kennedy Space Center.
- Dr. Lori Glaze as associate administrator of HSMD.
- Wanda Peters, deputy associate administrator for RTMD.
Longtime Aeronautics Research Mission Directorate head Bob Pearce announced plans to retire after a 36-year NASA career.
Why it matters
This organizational realignment follows President Trump’s Executive Order Ensuring American Space Superiority, which calls on NASA to focus on advancing American leadership in space through accelerated lunar exploration, nuclear propulsion, and fostering the orbital economy. By consolidating mission focus and empowering leadership structures, NASA positions itself to deliver on ambitious goals like Artemis’ continued lunar exploration and establishing a sustained human presence on the Moon more rapidly and efficiently.
Background
The reorganization builds on priorities outlined during NASA’s Ignition event in March 2026, where Administrator Isaacman detailed the agency’s goals aligned with national space policy directives. The focus is on enhancing specialization at individual centers while fostering cross-center collaboration to meet both short- and long-term mission objectives.
NASA’s continued commitment to science and exploration innovation is reflected in maintaining the Science Mission Directorate and integrating advanced technology development under RTMD, which includes nuclear space reactor projects and aeronautics research important for future missions beyond Earth orbit.
