Exploration Systems Development Mission Directorate
The Exploration Systems Development Mission Directorate defines and manages systems development for programs critical to NASA’s Artemis program and planning for NASA’s Moon to Mars exploration approach. ESDMD manages the human exploration system development for lunar orbital, lunar surface, and Mars exploration.
NASA has established the Moon to Mars Program Office within ESDMD to focus on hardware development, mission integration, and risk management functions for programs critical to the agency’s exploration approach. Artemis missions will open a new era of scientific discovery and economic opportunity at the Moon while validating operations and systems and to prepare for human missions to Mars. The Moon to Mars Program Office oversees development of the Space Launch System rocket, Orion spacecraft, supporting ground systems, human landing systems, spacesuits, Gateway, and more related to deep space exploration. The new office will also lead planning and analysis for long-lead developments to support Mars missions.
