Simone Esposito,Armando Riccardi,Enrico Pinna,Alfio Puglisi,Fernando Quiros-Pacheco,Carmelo Arcidiacono,Marco Xompero,Runa Briguglio,Guido Agapito,Lorenzo Busoni,Luca Fini,Javier Argomedo,A. Gherardi,Guido Brusa,Doug Miller,Juan Carlos Guerra,P. Stefanini,Piero Salinari +17 more
TL;DR: The comparison of the performances offered by a Natural Guide Star (NGS) system upgraded with the state-of-the-art technology and those delivered by existing Laser Guides Star (LGS) systems suggests rethinking the current role ascribed to NGS and LGS in the next generation of AO systems.

TL;DR: The Herschel (HElium Resonant Scattering in the Corona and HELiosphere) experiment, to be flown on a sounding rocket, will investigate the helium coronal abundance and the solar wind acceleration from a range of solar source structures by obtaining the first simultaneous observations of the electron, proton and helium solar corona.
CCD cameras and Spacewire interfaces for HERSCHEL/SCORE suborbital mission.

TL;DR: In this article, a solar concentrator is adapted for tower-type systems, which comprises: - a supporting module (11), which supports at least one frame (12), - mirrors (13), which are connected to the at least 1 frame so that they can be oriented and cooperate so as to form an array mirror element (14), - means (15) for modulating the position of the frame on the module, and means (16) for orienting the mirrors (17) on the frame (18).
