(1) Large-Aperture, Low Areal Density, High Stiffness Mirrors: 4 to 8 m monolithic \u0026amp; 8 to 16 m segmented primary mirrors require larger, thicker, stiffer substrates. (2) Support System: Large-aperture mirrors require large support systems to ensure that they survive launch and deploy on orbit in a stress-free and undistorted shape. (3) Mid\/High Spatial Frequency Figure Error: A very smooth mirror is critical for producing a high-quality point spread function (PSF) for high-contrast imaging. (4) Segment Edges: Edges impact PSF for high-contrast imaging applications, contributes to stray light noise, and affects the total collecting aperture. (5) Segment-to-Segment Gap Phasing: Segment phasing is critical for producing a high-quality temporally stable PSF. (6) Integrated Model Validation: On-orbit performance is determined by mechanical and thermal stability. Future systems require validated performance models. We are pursuing multiple design paths give the science community the option to enable either a future monolithic or segmented space telescope. \u003cbr\u003e\u003c\/p\u003e","brand":"Bibliogov","offers":[{"title":"Paperback","offer_id":47596694601879,"sku":"9781289011116","price":1432.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/3471\/1191\/files\/9781289011116.webp?v=1774994790","url":"https:\/\/atlanticbooks.com\/products\/advanced-uvoir-mirror-technology-development-for-very-large-space-telescopes-9781289011116","provider":"Atlantic Books","version":"1.0","type":"link"}
