The Habitable Worlds Observatory (HWO) is NASA’s next astrophysics flagship mission concept recommended by the 2020 Decadal Survey on Astronomy and Astrophysics. Two community groups are guiding the early mission concept maturation activities for HWO: a Science, Technology, Architecture Review Team (START) and a Technical Assessment Group (TAG).

Working Groups being organized under the START and TAG will be exploring the HWO mission concept’s fundamental science goals and how best to pursue them. Participation in HWO Working Groups is open to the community, and while there is no deadline for expressing interest in participating, activities are anticipated to begin around the end of January 2024 and last throughout the calendar year. Please express interest in joining an HWO Working Group here: https://forms.gle/jwdexDLAfnKAt1eK6.
