ATSA- A Cold, Active Telescope for Space Astronomy
Dec 14, 2020
Martin, Stefan; Lawrence, Charles; Redding, David; Rodgers, Michael; Hurd, Kevin; Jewell, Jeffrey; Morgan, Rhonda; Phillips, Charles; Pineda, Claudia; Mennesson, Bertrand; Steeves, John, 2020, "ATSA- A Cold, Active Telescope for Space Astronomy", https://hdl.handle.net/2014/53298, SPIE Astronomical Telescopes + Instrumentation 2020, San Diego, California, December 14-18, 2020, JPL Open Repository
The National Academies’ Decadal Survey telescope studies have produced mission design concepts that plotpathways into the future to follow on from Hubble, Spitzer, JWST and NGRST. Considering the results of theLUVOIR and HabEx studies in particular, it is clear that segmented mir...
Validation of Diffraction Models With Experimental Results From the Princeton Starshade Testbed
Dec 14, 2020
Harness, Anthony; Shaklan, Stuart; Kasdin, N. Jeremy; Willems, Phillip; Balasubramanian, K.; Dumont, Philip; White, Victor; Yee, Karl; Muller, Rich; Vuong, Simon; Galvin, Michael, 2020, "Validation of Diffraction Models With Experimental Results From the Princeton Starshade Testbed", https://hdl.handle.net/2014/53299, SPIE Astronomical Telescopes + Instrumentation 2020, San Diego, California, December 14-18, 2020, JPL Open Repository
Starshades are a leading technology to detect and characterize Earth-like exoplanets. In this paper we report on optical experiments of sub-scale starshades that advance critical starlight suppression technologies in preparation for the next generation of space telescopes. These...
Goal-Oriented Architecture for Telescope Control Software

Marx, David; Kerna, Brian; Krista, John; Balasubramaniana, Bala; Riggsa, A. J. Eldorado; Cadya, Eric; Seoa, Byoung-Joon; Tanga, Hong; Pradaa, Camilo; Ruanea, Garreth; Shia, Fang; Noeckera, Charley; Crowther, Blake, 2020, "Prediction and Evaluation of the Image of the WFIRST Coronagraph Pupil at the Shaped-Pupil Mask", https://hdl.handle.net/2014/53301, SPIE Astronomical Telescopes + Instrumentation 2020, San Diego, California, December 14-18, 2020, JPL Open Repository
To create a high contrast field of view with a shaped pupil coronagraph (SPC), the telescope pupil is imaged onto the shaped pupil mask, the shaped pupil mask is designed and fabricated through a design optimization based on a given pupil wavefront, and deformable mirrors (DM) in...
