NASA is creating a Science, Technology, Architecture Review Team (START) to determine the science scope and needed observatory capabilities for the Habitable Worlds Observatory (HWO).

HWO was prioritized by the 2020 Astrophysics Decadal Survey and is slated to be the NASA Astrophysics flagship mission that will follow the Nancy Grace Roman Space Telescope. HWO will directly image and characterize exoplanets and conduct a wide range of groundbreaking astrophysics observations in the ultraviolet-visible-near infrared wavelength range.

The Dear Colleague Letter and detailed Terms of Reference can be found on the NASA Astrophysics Great Observatories Maturation Program (GOMAP) webpage.
