Modal estimation of high-order wavefront drifts on coronagraphic testbeds for high-contrast direct imaging of exoplanets
Saikrishna Manojkumar, Susan F. Redmond, Leonid Pogorelyuk +13
Long-term wavefront stability will be critical for the upcoming Habitable Worlds Observatory which aims to directly image exo-Earths. Mechanical and thermal instabilities induce sl…

Julien H. Girard, Eric Cady, Neil T. Zimmerman +42
Roman is set to launch in weeks! The Coronagraph Instrument - technology pathfinder for future direct imaging missions - is ready to fly too. According to predictions, laboratory t…
The Roman Coronagraph Community Participation Program: target database and tools
Dmitry Savransky, Rifah Tasnim, Saanika Choudhary +13
The Nancy Grace Roman Space Telescope, set to launch in Fall 2026, will carry the Coronagraph Instrument, which will, for the first time, demonstrate high-contrast imaging with act…
Early Architecture Concepts for the Habitable Worlds Observatory -- System Design, Modeling, and Analysis
Alice, Liu, Marie Levine +30
The Habitable Worlds Observatory (HWO), NASA's next flagship science mission, follows in the tradition of the Nancy Grace Roman Space Telescope and other preceding great observator…
