The Space Telescope Science Institute (STScI), a division of the Association of Universities for Research in Astronomy, Inc., was awarded a $949,555 grant by NASA's Shared Services Center to support the development of science simulation tools, instrument design, and testbed capabilities for the Habitable Worlds Observatory (HWO). The contract deliverables include: (1) an initial Observatory Architecture Exposure Time Calculator serving as a community tool to assess science feasibility for general astrophysics; (2) coronagraph design specifications for the new telescope to support integrated modeling and predict science yields; (3) laboratory demonstrations of high-contrast post-processing approaches; and (4) testbed design to support technology maturation of Observatory systems. The work is scheduled for completion by September 30, 2026, and will be performed at STScI's Baltimore, Maryland location.

This grant, awarded without set-aside designation through open competition, represents part of NASA's broader investment in developing the next-generation space telescope capabilities for exoplanet detection and astronomical observation. STScI, as a non-profit organization managing major astronomical observatories on behalf of federal agencies, brings extensive expertise in space-based astronomical research and scientific instrumentation development. The contract supports NASA's strategic objectives in advancing space exploration and astrophysical research through the development of critical tools and technologies needed to maximize the Habitable Worlds Observatory's scientific potential and operational effectiveness.

Support the habitable worlds observatory (HWO) science simulation tools, instrument design, and testbed development. IT is necessary to develop or perform 1) the initial observatory architecture s exposure time calculator as a community tool to evaluate science feasibility for general astrophysics, 2) a coronagraph design is needed for a new telescope to support integrated modeling and predict science yields, 3) laboratory demonstrations of high contrast post-processing approaches, and 4) testbed design is needed to support technology maturation of observatory systems.
