Habitable Worlds Observatory Science, Technology, Architecture Review Team and Virtual Town Hall

May 5, 2023 @ 11:30 am - 12:30 pm

Habitable Worlds Observatory

Dear Colleagues,

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.

A Dear Colleague Letter and detailed Terms of Reference were released on April 11, 2023, to solicit self-nominations for people to serve on the START. We want START to be composed of people from diverse backgrounds and disciplinary perspectives, and encourage scientists, engineers, and technologists with terminal degrees in their field to self-nominate. These documents and more can be found on the NASA Astrophysics Great Observatories Maturation Program (GOMAP) webpage at:

NASA will host a Virtual Town Hall meeting today, Friday, May 5, 2023, 11:30 AM – 12:30 PM (Eastern Time) to answer questions from the community regarding the HWO and the START. To connect to the town hall meeting, users with Microsoft Teams click here or follow this link: https://tinyurl.com/HWOSTART Users without Teams can follow the link and choose the join with their browser.
