"Chtoby vibraciya samoleta ne peredavalas' teleskopu, ego budet uderzhivat' v neizmennom polozhenii sistema giroskopov i gidravlicheskih podvesok".
Da, no v tehnike inogda ochen' vazhen i faktor dvoiki. A dlya UF snimkov (dlina volny na poryadok koroche), sootvetstvenno, i podderzhanie napravleniya teleskopa trebuetsya na poryadok tochnee. Vprochem, ya konkretnyh cifr ne znayu; esli vy znaete, napishite.
"U menya est' podozrenie, chto vibraciyu udaetsya gasit' polnost'yu..."
Polnost'yu nikogda nichego ne byvaet Mozhno oslabit' na n dB. Naskol'ko veliko eto n, ya ne v kurse. A vy?
"Sprashivaetsya, zachem vse eti slozhnosti s sharami i samoletami, esli uzhe otrabotana tehnologiya zapuska kosmicheskih Habblov? Ved' povtoryat' (kak rossiiskie Protony i Soyuzy) v desyatki raz deshevle."
Vy znaete konkretnye cifry -- stoimost' zapuska Habbla; stoimost' ego podderzhki i t.d.? Tol'ko postroika (bez zapuska) oboshlas' bolee chem v milliard dolarov. Vot citaty:
"From its original total cost estimate of about 400 million dollars, the telescope had by now cost over US$2.5 billion to construct. Hubble's cumulative costs up to this day are estimated to be several times higher still, with U.S. ... estimated at between 4.5 and 6 billion USD and Europe's financial contribution at 593 million Euros (1999 estimate)"
"The shuttle mission to refurbish the Hubble Space Telescope one last time in May 2008 will cost about $900 million."
Zamet'te: nachal'naya stoimost' (postroit' + zapustit') uzhe men'she poloviny polnyh zatrat (v osnovnom, dumayu, iz-za treh obsluzhivayushih missii). Tak chto dazhe esli vy umen'shite do nulya stoimost' zapuska, sil'no polnye zatraty eto ne umen'shit.
