The Habitable Worlds Observatory Technology Development Plan
Summary
Astrobiology.com (Keith Cowing) reproduces the Habitable Worlds Observatory (HWO) Technology Development Plan, a primary deliverable of NASA’s HWO Technology Maturation Project Office (TMPO), formed August 2024. The plan identifies critical technologies enabling the mission, defines a process for assessing their Technology Readiness Level (TRL), and lays out a strategy to mature those technologies to TRL 5 before HWO’s Mission Concept Review (MCR), targeted for the end of the decade. Technologies are organized along three tracks: Coronagraph System technologies, Ultra-stable Telescope System technologies, and High-sensitivity Ultraviolet and Visible Instrumentation technologies, plus additional emerging/enhancing technologies. HWO was selected by the 2020 Decadal Survey in Astronomy and Astrophysics to search for and characterize habitable exoplanets while enabling broader transformative astrophysics.
