WASHINGTON (NASA PR) — NASA Administrator Bill Nelson announced Tuesday the agency is creating two new mission directorates that will best position the agency for the next 20 years.

The move separates the agency’s current Human Exploration and Operations Mission Directorate into the new Exploration Systems Development Mission Directorate (ESDMD) and Space Operations Mission Directorate.

NASA is making the changes because of increasing space operations in low-Earth orbit and development programs well underway for deep space exploration, including Artemis missions.

Leadership will discuss the change and the future of NASA during an employee town hall broadcast live on NASA Television, the NASA app, and the agency’s website at noon EDT today.

Media are invited to a follow-on teleconference at 2:30 p.m., with audio streaming live online.
