Its purpose is to survey the atmospheres of known exoplanets through transit spectroscopy. The launch is scheduled for 2029. The scientific payload consists of an off-axis, unobscured Cassegrain telescope feeding a set of photometers and spectrometers in the waveband 0.5-7.8 µm and operating at cryogenic temperatures (55 K). The Telescope Assembly is based on an innovative fully aluminium design to tolerate thermal variations to avoid impacts on the optical performance; it consists of a primary parabolic mirror with an elliptical aperture of 1.1 m (the major axis), followed by a hyperbolic secondary that is mounted on a refocusing system, a parabolic re-collimating tertiary and a flat folding mirror directing the output beam parallel to the optical bench. An innovative mounting system based on 3 flexure hinges supports the primary mirror on one of the optical bench sides. The instrument bay on the other side of the optical bench houses the Ariel IR Spectrometer (AIRS) and the Fine Guidance System / NIR Spectrometer (FGS/NIRSpec). The Telescope Assembly is in phase B2 towards the Critical Design Review; the fabrication of the structural and engineering models has started; some components, i.e., the primary mirror and its mounting system are undergoing further qualification activities. This paper aims to update the scientific community on the progress concerning the development, manufacturing and qualification activity of the ARIEL Telescope Assembly. date: 2024-08-23 date_type: published publisher: SPIE official_url: http://dx.doi.org/10.1117/12.3018735 oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 2323475 doi: 10.1117/12.3018735 lyricists_name: Tinetti, Giovanna lyricists_id: GTINE95 actors_name: Flynn, Bernadette actors_id: BFFLY94 actors_role: owner full_text_status: public pres_type: paper publication: Space Telescopes and Instrumentation 2024: Optical, Infrared, and Millimeter Wave volume: 13092 place_of_pub: Bellingham, WA, USA pagerange: 130921C event_title: SPIE Astronomical Telescopes + Instrumentation 2024 event_dates: 16 Jun 2024 - 22 Jun 2024 book_title: Proceedings of SPIE: Space Telescopes and Instrumentation 2024: Optical, Infrared, and Millimeter Wave editors_name: Coyle, Laura E editors_name: Matsuura, Shuji editors_name: Perrin, Marshall D citation: Pace, Emanuele; Adler Abreu, Manuel; Alonso, Gustavo; Barroqueiro, Bruno; Bocchieri, Andrea; Brienza, Daniele; Brucalassi, Anna; ...
