Does anyone can merge as below to here?


We should wait for the payload list to be released by official media before merging the threads.

What was the rocket's serial number?

I'm not sure about the optical satellites part, this is not a usual launch time for optical Earth observation satellites in SSO (with reference to LTDN/LTAN). This is a "dawn-dusk terminator" SSO which is more linked with radar/SAR satellites, and there are 8 planned as quoted.

I have yet to see any detailed description of the 2 satellites in Chinese social media so far, only their uses.

OK the company has an English press release after the April launch and here it reads:

Quote
SuperView Neo-2 service customers for SAR images with 50 cm resolution in spotlight mode. First two 50 cm SAR satellites will be launched within the next few months.

So yeah it seems these are SAR satellites.

China Siwei releases 30 cm imagery from SuperView Neo
Quote
China Siwei’s newest commercial imaging satellites SuperView Neo-1 01 and 02 were successfully launched into space Apr. 29 aboard a Long March rocket. They upgrade China Siwei’s existing 50 cm resolution satellites SuperView-1 constellation, and provide 30 cm imagery to customers who are eager for more channels of very high-resolution imagery.

China Siwei is developing a SuperView Neo commercial satellite system, which includes at least 28 satellites dividing into 3 series. SuperView Neo-1 aim to provide 20 to 30 cm optical images. SuperView Neo-2 service customers for SAR images with 50 cm resolution in spotlight mode. First two 50 cm SAR satellites will be launched within the next few months. SuperView Neo-3 can acquire large swath-width optical image with resolution better than 1 meter.

The images taken May. 3 showcase SuperView Neo-1’s imaging capabilities with pictures of McCarran International Airport in Las Vegas of USA and Qatar’s capital Doha. With 30 cm resolution customers can obtain greater detail for imagery analysis, and more ground information for intelligent mapping.

SuperView Neo-1 would add the company’s collection capacity to another 1.5 million square kilometers per day, and lift revisit capacity to 2 times per day with high agility. They will provide massive data and timeliness service for defence security, civil mapping, agriculture management, energy and transportation infrastructure, disaster monitoring and so on.

The first phase of China's new generation of commercial remote sensing satellite system was successfully constructed

According to reports, in May 2020, China Siwei launched the demonstration of a new generation of commercial remote sensing satellite systems. The space segment plans to launch a total of 28 satellites of "16+4+8", and synchronously build and match the ground segment (including measurement and control) based on "Siwei Cloud". , reception, processing, application); China's four-dimensional new-generation commercial remote sensing satellite system will be fully completed in 2025, the system will have a high global revisit capability of 25 times a day, a daily collection area of more than 30 million square kilometers, and a high collection capability of 2 Emergency delivery capability within hours. At present, the launch plan of 28 satellites in the space segment can be expanded to 56 satellites in the future.
I think the first stage of Siwei Cloud is as below:
Siwei Gaojing-1 01-02 launched in April 30 and rest 03-16 will be launched,
Siwei Gaojing-2 01-02 launched in July 15 and rest 03-04 will be launched,
Siwei Gaojing-3 01-08 will be launched in near future.
