Description
The configuration of the CZ-5B variant consists of the Long March 5 core stage with its four strapped-on liquid-fueled boosters, but the usual second stage will be absent; in place of the second stage would be heavier low earth orbit payloads.

CASC 1999The China Aerospace Science and Technology Corporation (CASC) is the main contractor for the Chinese space program. It is state-owned and has a number of subordinate entities which design, develop and manufacture a range of spacecraft, launch vehicles, strategic and tactical missile systems, and ground equipment. It was officially established in July 1999 as part of a Chinese government reform drive, having previously been one part of the former China Aerospace Corporation. Various incarnations of the program date back to 1956.

TBD December, 2027
Status: To Be Determined
Mission:
Xuntian, formerly known as the Chinese Space Station Telescope (CSST), is a Chinese space telescope designed to perform high-resolution, large-area, multi-band imaging and slit-less spectroscopy surveys of the sky at ultraviolet to infrared wavelengths of 255 – 1000 nm. The survey camera is slated to cover approximately 17500 square degrees of the sky in various bands, reaching maximum magnitudes of about 26. Xuntian will carry a survey camera, a tera-hertz receiver, a multi-channel imager, an integral field spectrograph, and a cool planet imaging coronagraph. Xuntian will be launched to a Low Earth Orbit that will be co-orbiting with the Tiangong space station/Chinese Space Station, which will allow for periodic docking with the station for regular maintenance by astronauts.
