The Long March 12 is a two-stage launch vehicle developed by the Shanghai Academy of Spaceflight Technology.
The second stage of the Long March 12 is powered by two YF-115 engines generating 36 tons of thrust.
The Long March 12 launch utilized automated control of the launch process, enabled by standardized synchronized clocks across multiple systems.
This mission marked the 3rd launch of the Long March 12 vehicle.
The Long March 12 has a payload capacity of 12,000 kilograms to low Earth orbit and 6,000 kilograms to a 700-kilometer sun-synchronous orbit.
The loading of the second stage for the CZ-12 launch is now starting.
CZ-12's launch is scheduled to occur in 1.5 hours.
The planned launch date for the CZ-12 is November 10.
A CZ-12 was transported to Pad-2 of Wenchang commercial.
The CZ-12 rocket is scheduled to launch on November 10th.
The delay of the CZ-12 Y3 launch is not due to payload availability.
There are two different satellite variants believed to be in use for the GuoWang constellation, with a larger version used on Long March 5B and smaller ones used on Long March 6A or Long March 12.
Hardware for upcoming Long March 8A missions and a Long March 12 were properly protected to avoid launch delays.
CZ-12 Y3 is in HCSLC's assembly building and may launch later this month.
Two satellite variants are believed to be in use for the GuoWang constellation, one larger variant for rockets like the Long March 5B and smaller ones for the Long March 8A or Long March 12.
Completion of the CZ-12-series pad is aimed for mid-October 2023.
CASC (China Aerospace Science and Technology Corporation) is involved with the CZ-12-series pad.
The JSLC 2-CZ-12 launch pads are progressing faster than those in Hainan.
The new Hainan commercial space launch center hosted its inaugural launch on 2024-11-30, which was the debut flight of the Long March 12.
The Wenchang Commercial Space Launch Site is a distinct commercial spaceport separate from Wenchang’s existing national spaceport and was used for the Long March 12 debut.
