A photo of the Earth from space. Only a small, curved section of the Earth is visible at the top of this image. On the Earth, there are swirling white clouds and blue water peeking through gaps in the clouds. The rest of the image is black.


Building on the technological foundations established by the James Webb and Nancy Grace Roman Space Telescopes, NASA’s Great Observatory Maturation Program (GOMAP) will unite government, industry, and academia to develop the technologies needed for NASA’s next flagship astrophysics mission.

This program will draw on lessons from previous NASA missions to streamline development of the in-space serviceable Habitable Worlds Observatory (HWO) concept and decrease budget and schedule risks for a future mission. Early investments in both technology and analysis would help make the future Habitable Worlds Observatory a scientific, technical, and programmatic success while keeping the United States as a global leader in space science.

GOMAP will focus on several key early activities to ensure future flagship telescopes, starting with HWO, are developed on a predictable cost and schedule while minimizing risks of overruns. GOMAP’s coordinated activities will ensure the scope of HWO is clearly defined, will advance the technologies that will enable HWO to deliver its revolutionary science, and plan additional steps for long-term preparation.

The GOMAP leadership team includes:

  • GOMAP Program Executive: Julie Crooke, NASA Headquarters
  • GOMAP Program Scientist: Megan Ansdell, NASA Headquarters
  • GOMAP Deputy Program Scientist: Joshua Pepper, NASA Headquarters
