진짠데? 초기 KH-11하고 허블하고 필름이 동일함.
KH-11은 76년, 허블은 90년이잖음 오죽하면 나사가 남는거 없냐고 물어봤다니까
When NRO donated two Optical Telescope Assemblies (OTA) to NASA in January 2011, they were suspected to be KH-11 series "extra hardware", but were later attributed to the Future Imaging Architecture program. The donated OTAs feature a three-mirror anastigmat (TMA) optical design, without the tertiary mirror. The f/1.2 primary has a diameter of 2.4 m, and is refocused by the secondary to give an overall f/8 focal ratio, making the optical telescope assembly shorter than that of HST. With the addition of the tertiary mirror, this will produce a much wider field than Hubble's 2-mirror f/24 Ritchey–Chrétien optical design, making it a potentially ideal observatory for dark energy or other astrophysics surveys. The secondary mirror is mounted on a hexapod to increase the side-viewing and ground scanning ability for the originally intended reconnaissance mission.
