How Will China's Xuntian Survey Space Telescope Differ from Hubble?

Welcome to another episode of the Dongfang Hour! In this episode, we provide an overview of the Xuntian Space Telescope (launching in 2023), and compare it to the Hubble Space Telescope operated by the European Space Agency (ESA) and NASA. As always, lots of fun facts & cool physics! 

Xuntian, also known as the Chinese Survey Space Telescope or Chinese Space Station Telescope, is a planned Chinese space telescope currently under development. 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 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.

Xuntian is planned for launch in 2024 on China's Long March 5B rocket. It will to co-orbit with China's new Tiangong Space Station in slightly different orbital phases, allowing for periodic docking with the station.
