PROVIDENCE: a ground station for space observation
P. -L. Mayeur, J. -F. Sauvage, T. Fusco +25
PROVIDENCE is an ONERA-led project to install a new-generation optical ground station at the Haute-Provence Observatory (OHP) in South of France. Built around a 2.5-meter aperture,…
High-contrast imager for complex aperture telescopes (HiCAT): 8. Dark zone demonstration with simultaneous closed-loop low-order wavefront sensing and control
Rémi Soummer, Emiel H. Por, Raphaël Pourcelot +27
We present recent laboratory results demonstrating high-contrast coronagraphy for the future space-based large IR/Optical/Ultraviolet telescope recommended by the Decadal Survey. T…
Active deployable primary mirrors on CubeSat
Noah Schwartz, Maria Milanova, William Brzozowski +9
The volume available on small satellites restricts the size of optical apertures to a few centimetres, limiting the Ground-Sampling Distance (GSD) in the visible to typically 3 m a…
3D printing for astronomical mirrors
Melanie Roulet, Carolyn Atkins, Emmanuel Hugot +3
3D printing, also called additive manufacturing, offers a new vision for optical fabrication in term of achievable optical quality and reduction of weight and cost. In this paper w…
Superpolished OAPs for WFIRST CGI
Melanie Roulet, Emmanuel Hugot, Carolyn Atkins +3
Exoplanet imaging requires super polished off-axis parabolas (OAP) with the utmost surface quality. In this paper we describe an innovative manufacturing process combining 3D print…
Space Project for Astrophysical and Cosmological Exploration (SPACE), an ESA stand-alone mission and a possible contribution to the Origins Space Telescope
Denis Burgarella, Andrew Bunker, Rychard Bouwens +30
We propose a new mission called Space Project for Astrophysical and Cosmological Exploration (SPACE) as part on the ESA long term planning Voyage 2050 programme. SPACE will study g…
