Xuntian (Chinese: 巡天; pinyin: Xún Tiān; lit. 'Space Sentinel'), also known as the Chinese Survey Space Telescope[2][3] (CSST) (Chinese: 巡天号空间望远镜; pinyin: Xúntiānhào Kōngjiān Wàngyuǎnjìng) is a planned Chinese space telescope currently under development.[4] It will feature a 2 meter (6.6 foot) diameter primary mirror and is expected to have a field of view 300–350 times larger than the Hubble Space Telescope.[5] This will allow the telescope to image up to 40 percent of the sky using its 2.5 gigapixel camera over ten years.
Xuntian is scheduled for launch in December 2023[2] on a Long March 5B rocket to co-orbit with the Tiangong space station in slightly different orbital phases, which will allow for periodic docking with the station.[6] The telescope will be fully operational by 2024.[7]
