This is a very interesting, very capable and possibly overambitious project.

The telescope has a 2m mirror, and appears to cover the uv-visible wavelength band. The sensors are quoted as being 81 megapixels (9000*9000 if square), which is larger than anything I have read about in US or European projects. It has a 2.5 gigapixel camera, and a field of view 300-350 times larger than Hubble.

The project does indeed sound very ambitious. The camera is huge and data downlink requirements must be enormous. LEO instead of L2 helps there of course, but there are good reasons why (large) western space observatories are now almost all sent to L2.

Presumably the serviceability requirement (and perhaps others) outweighs those reasons in this case.

Xuntian to have a 300 times wider view than Hubble:

Very cool CGI of on-orbit maintenance of Xuntian space telescope appeared on CCTV news. Very serious question: where is Shenzhou, the life vessel for astronauts..

The telescope is currently in the phase of prototyping, so launch in 2023 is highly questionable.

This seems like an improved Hubble. Docks to the space station for easy servicing. Wide field. Modern instruments.
This will give China some capabilities nobody else has and make them a serious player in astronomy.

Great pictures. Much to ponder but wouldn't it be easier to merge with the existing Xuntian thread?

Blackstar · « **Reply #28 on:** 02/18/2023 11:57 pm »

I'd argue that the other thread should be moved here. It's a science project, not a "Chinese launcher" project.

Xuntian/CSST space telescope will be launched by the end of 2024 at the earliest, according to project scientist Liu Chao in a seminar at Shanghai Planetarium. Some details of the project are revealed in the presentation. Source: https://buff.ly/423ADBD

😮CSST space telescope will enter the final prototype phase in April 2024.

Looks like there was some rumors on Weibo, but the information disappeared. Still trying to confirm.

From other forum, "Looks like the latest schedule calls for completion in September of 2026 and launch in December."

Looks like launch is schedule for December 21, 2026.

Satori · « **Reply #38 on:** 09/12/2024 07:06 pm »

According to the following presentation, the launch will now take place around 2027.
