2023中国航天首飞箭之“长征六号丙”，新一代运载火箭又将迎来新成员

In 2023, the "Long March 6C", the first rocket of China's aerospace industry, will usher in new members of the new generation of launch vehicles

"Chang Liu C" is a medium-sized two-stage liquid carrier rocket, which has been adaptively improved on the basis of inheriting the core module of "Chang Liu Jia". "Chang Liu Cing" removed the four solid boosters of "Chang Liu Jia" remote one, and the take-off mass of a single solid booster was 70 tons. This item reduced the rocket take-off mass by 280 tons, and replaced it with a fairing with a diameter of 3.35 meters. The length of the rocket body is slightly reduced by several meters. Therefore, it can be concluded that the "Chang Liu Cing" arrow has a length of more than 40 meters, a take-off mass of more than 200 tons, and a take-off thrust of about 240 tons. Its 700-kilometer SSO transport capacity can be maintained under the condition that the basic configuration of the "Chang Liujia" remains unchanged. About 2 tons.

This is also impossible CZ-6C maiden.

maybe just 2c or 2d

The June 20 launch won't be of the Jilin-1 satellite batch.

The countdown to launch has officially entered! The "One Arrow 41 Satellites" program will be launched at the Taiyuan Satellite Launch Center in the near future.
　　
This historic moment, which will create the record for the largest number of satellites launched by my country's spaceflight at a time, has attracted much attention.
　　
On June 14, a special reporter from China Jilin.com walked into the Taiyuan Satellite Launch Center to reveal the story behind "41 satellites with one arrow" before the satellite is about to launch .

There is no plan to launch Kuaizhou-1A from Taiyuan this year.

[Vahe231991]

There is no plan to launch Kuaizhou-1A from Taiyuan this year.

So if there won't a Kuaizhou-1A launch on June 20, is it possible that the Hongtu-1 02 could be launched that day?

Drop zone is different from Hongtu-1 01.

[mikezang]

new NOTAM issued, the first drop zone looks like CZ-4C.

[Galactic Penguin SST]

new NOTAM issued, the first drop zone looks like CZ-4C.

More like CZ-6 IMHO - coordinates are almost a perfect match.

Only some 1st drop zone looks like similar, here are past CZ-6...

[mikezang]

What launch vehicle do you think from past luanched drop zones?
1. CZ-4C 长征四号丙
2. CZ-4B 长征四号乙
3. CZ-2D 长征二号丁
4. CZ-6   长征六号

[mikezang]

It is said the payloads might be Haiyang-3A/B (海洋三号A/B).

The website Gunter's Space Page has the Haiyang-3A and Haiyang-3B as planned for launch from the CZ-6.

[Vahe231991]

Has the launch taken place?

[mikezang]

The Shiyan-25 launched by CZ-6.

[mikezang]

This is Y12.
