Laser Guide Star for Large Segmented-Aperture Space Telescopes, Part I: Implications for Terrestrial Exoplanet Detection and Observatory Stability
Ewan S. Douglas, Jared R. Males, James Clark +4
Precision wavefront control on future segmented-aperture space telescopes presents significant challenges, particularly in the context of high-contrast exoplanet direct imaging. We…
The Habitable Exoplanet Observatory (HabEx) Mission Concept Study Interim Report
B. Scott Gaudi, Sara Seager, Bertrand Mennesson +79
For the first time in human history, technologies have matured sufficiently to enable a mission capable of discovering and characterizing habitable planets like Earth orbiting sunl…
Modeling coronagraphic extreme wavefront control systems for high contrast imaging in ground and space telescope missions
Jennifer Lumbres, Jared Males, Ewan Douglas +17
The challenges of high contrast imaging (HCI) for detecting exoplanets for both ground and space applications can be met with extreme adaptive optics (ExAO), a high-order adaptive…
The Deformable Mirror Demonstration Mission (DeMi) CubeSat: optomechanical design validation and laboratory calibration
Gregory Allan, Ewan S. Douglas, Derek Barnes +9
Coronagraphs on future space telescopes will require precise wavefront correction to detect Earth-like exoplanets near their host stars. High-actuator count microelectromechanical…
Wavefront Sensing in Space: Flight Demonstration II of the PICTURE Sounding Rocket Payload
Ewan S. Douglas, Christopher B. Mendillo, Timothy A. Cook +2
A NASA sounding rocket for high-contrast imaging with a visible nulling coronagraph, the PICTURE payload, has made two suborbital attempts to observe the warm dust disk inferred ar…
Life Beyond the Solar System: Remotely Detectable Biosignatures
Shawn Domagal-Goldman, Nancy Y. Kiang, Niki Parenteau +38
For the first time in human history, we will soon be able to apply the scientific method to the question "Are We Alone?" The rapid advance of exoplanet discovery, planetary systems…
