Xuntian

China

The Xuntian (pinyin: Xúntiān, lit. 'Tour of Heaven') or Chinese space station survey telescope (CSST) (pinyin: Xúntiān Kōngjiān Wàngyuǎnjìng) is a Chinese space telescope under development. The telescope will feature a 2-meter (6.6 foot) diameter primary mirror and is expected to have a field of view approximately 300 to 350 times larger than that of the Hubble Space Telescope. Its 2.5-gigapixel camera is designed to survey up to 40 percent of the sky. As of 2026, Xuntian is scheduled for launch in 2027 aboard a Long March 5B rocket. It is planned to operate in a co-orbital arrangement with the Tiangong space station, allowing periodic docking for servicing and maintenance.
