Xuntian

Xuntian (Chinese: 巡天; pinyin: Xún Tiān; lit. 'Space Sentinel'), also known as the Chinese Survey Space Telescope[2] or Chinese Space Station Telescope (CSST) (Chinese: 巡天号空间望远镜) is a planned Chinese space telescope currently under development.[3] It will feature a 2 meter (6.6 foot) diameter primary mirror and is expected to have a field of view 300 times larger than the 32 year old Hubble Space Telescope. This will allow the telescope to image up to 40 percent of the sky using its 2.5 gigapixel camera over ten years.
