The Habitable Worlds Observatory Technology Development Plan

The Habitable Worlds Observatory (HWO) is NASA’s next large space telescope, selected by the 2020 Decadal Survey in Astronomy and Astrophysics to search for and characterize habitable exoplanets while enabling a broad range of transformative astrophysics. In August 2024, the HWO Technology Maturation Project Office (TMPO) was formed to begin exploring the HWO science, technology, and mission architectures toward a Mission Concept Review (MCR) at the end of the decade. A primary deliverable of this effort is this technology development plan that identifies critical technologies that enable the mission, defines a process for assessing the readiness of those technologies, and outlines a strategy for developing those technologies to a Technology Readiness Level (TRL) of 5 before the MCR. This document covers technologies organized along three “tracks”: Coronagraph System technologies, Ultra-stable Telescope System technologies, and High-sensitivity Ultraviolet and Visible Instrumentation technologies. Additional emerging and enhancing technologies are also discussed.

The Habitable Worlds Observatory Technology Development Plan

The Habitable Worlds Observatory (HWO) is NASA’s next large space telescope, selected by the 2020 Decadal Survey in Astronomy and Astrophysics to search for and characterize habitable exoplanets while enabling a broad range of transformative astrophysics. In August 2024, the HWO Technology Maturation Project Office (TMPO) was formed to begin exploring the HWO science, technology, and mission architectures toward a Mission Concept Review (MCR) at the end of the decade. A primary deliverable of this effort is a technology development plan that identifies critical technologies that enable the mission, defines a process for assessing the readiness of those technologies, and outlines a strategy for developing those technologies to a Technology Readiness Level (TRL) of 5 before the MCR. In this paper we summarize the HWO technology development plan which comprises three “tracks”: Coronagraph System technologies, Ultra-stable Telescope System technologies, and High-sensitivity Ultraviolet and Visible Instrumentation technologies. Each track has completed an initial assessment of technology gaps, prioritized the gaps for investment, and laid out development roadmaps to mature candidate technologies to close those gaps.

Servicing the Habitable Worlds Observatory

The Habitable Worlds Observatory is a large ultraviolet/optical/infrared space telescope being planned for launch in the 2040s. The project was recommended in the National Academies Decadal Survey for Astronomy and Astrophysics Pathways to Discovery in Astronomy and Astrophysics for the 2020s. The Habitable Worlds Observatory will be the first space telescope designed specifically to search for signs of life on planets orbiting other stars. This "super-Hubble" will provide powerful capabilities for transformational astrophysics, from our cosmic backyard of the solar system, to the distant universe, and everything in between. The project will leverage past NASA flagship investments from the Hubble Space Telescope, the James Webb Space Telescope, and the Roman Space Telescope. Critical to the success of the project is to draw on decades of lessons from the development of these previous telescopes and other NASA missions to streamline the development of the Habitable Worlds Observatory in order to decrease budget and schedule risks.
