On CNSA –China National Space Administration    …. ChangZheng  Long March 12 first flight rocket joint rehearsal…. At  Hainan Commercial Space Launch Center. Wenchang, Hainan Province, China, People’s Republic of China  At 7:00 a.m Beijing time . on October 8th 2024 .. , the joint rehearsal mission execution team had assembled in the Sanping factory. At the pre-shift meeting for the rocket joint rehearsal, General Dispatcher Cao Guobin was arranging various tasks in detail. At 8:00, the rocket was placed on the long rocket transport vehicle to prepare for the first joint rehearsal mission after the National Day. At 8:30, as the rocket slowly drove into the No. 2 launch station in the launch area, a new space journey will begin again……rocket with a diameter of 3.8 meters among the “Long March” rockets.

China’s most powerful single-core rocket for low-orbit transport…

The Long March 12 (LM-12/CZ-12) is a new generation of carrier rocket developed by the Eighth Academy of China Aerospace Science and Technology Corporation. It is a medium-sized cryogenic liquid carrier rocket with a two-stage tandem configuration. The first and second stages are all powered by liquid oxygen-kerosene engines. The rocket was originally the Eighth Academy’s bid for a new generation of manned carrier rockets, and was later renamed XLV20. The original 5CBC configuration (5 cores in parallel for the takeoff stage) was changed to a single core stage configuration.

The first stage of the Long March 12 is equipped with four YF-100K liquid oxygen/kerosene engines, using an oxygen-rich staged combustion cycle, using pump-back swing, supporting bidirectional swing of ±8 degrees, and a thrust adjustment range of 65%~105%. The sea level thrust of a single engine is about 128 tons (1250 kN), and the sea level specific impulse is 301.84 seconds. The second stage is equipped with two YF-115 liquid oxygen/kerosene engines, using an oxygen-rich staged combustion cycle, supporting bidirectional swing of ±4 degrees, a thrust adjustment range of 80%~100%, a vacuum thrust of about 18 tons (180 kN), and a vacuum specific impulse of about 342 seconds.

The Long March 12 rocket is 59 meters high, with a first and second stage diameter of 3.8 meters. It can be equipped with optional fairings with diameters of 4.2 meters and 5.2 meters. It has a takeoff mass of 433 tons and a maximum takeoff thrust of about 510 tons (5,000 kilonewtons). The rocket has a carrying capacity of no less than 10 tons in a low-Earth orbit (LEO) at an altitude of 300 kilometers and a carrying capacity of no less than 6 tons in a sun-synchronous orbit (SSO) at an altitude of 700 kilometers.

The Long March XII rocket is the first 3.8-meter-diameter model of the Long March rocket. It will also become China’s single-core-stage carrier rocket with the largest takeoff mass and the strongest low-orbit carrying capacity in service.

The first flight of the YF-100K engine!

On April 28, 2024, the YF-100K liquid oxygen-kerosene engine developed by the Sixth Academy of China Aerospace Science and Technology Corporation completed a four-engine parallel ignition test. The total thrust of the engine exceeded 500 tons. This was the first large-thrust liquid oxygen-kerosene engine four-engine parallel ignition test, and the four-engine parallel scheme was fully verified.

The YF-100K was born with the proposal of China’s manned lunar landing plan and the need to demonstrate the new generation of manned carrier rockets. It is based on the improvement and optimization of the YF-100. This engine is the main power of China’s new generation of manned carrier rocket “Long March 10”. It adopts pump back swing. Compared with the YF-100 in use, it has the advantages of small mass eccentricity, small swing envelope, and easy layout of swing components.

The maiden flight of the Long March 12 rocket is also the maiden flight of the YF-100K engine, which will test its performance in actual launches and accumulate flight samples for the main power of the Long March 10 takeoff stage. At the same time, the YF-100K will pave the way for the improvement and upgrading of the new generation of carrier rockets currently in service, such as the Long March 5, whose four boosters are equipped with a total of 8 YF-100 engines. By replacing them with the YF-100K engines with better performance, the rocket will further release its already powerful carrying capacity.

It is expected that in August 2024, the Long March 12 (Yao-1) carrier rocket will carry out its maiden flight at the No. 2 station of the Hainan Commercial Space Launch Center in China, and China’s new generation of carrier rockets will welcome a new member. At the same time, this is also the first rocket launch of the Hainan Commercial Space Launch Center, which means that China’s first commercial space launch center has officially been put into use.

On CNSA –China National Space Administration   The Tianzhou-8 cargo spacecraft will be launched next month! From Wenchang Spacecraft launch Center, Hainan province, China, People’s Republic of China.. the November Date of year 2024..   Towards the Tiangong-China Space Station..

According to the plan at the beginning of 2024, China’s manned space program plans to carry out four launch missions this year, including two manned launch missions and two cargo launch missions. At present, the launch missions of the “Tianzhou-7” cargo spacecraft and the “Shenzhou-18” manned spacecraft have been carried out in the first half of the year, and the “Shenzhou-19” and “Tianzhou-8” launch missions will be carried out next.

According to the original plan, the Tianzhou-8 cargo spacecraft will be launched before the Shenzhou-19 manned spacecraft. Due to the impact of the super typhoon Makar, the ground facilities of the Wenchang launch site were affected to a certain extent, and the launch was postponed to after the Shenzhou-19 mission. It is expected that in early to mid-November, at the 201 station of the Wenchang launch site, the Tianzhou-8 cargo spacecraft will be launched to the Chinese space station by the Long March-7 Yao-9 carrier rocket. The spacecraft will adopt the rapid rendezvous and docking mode to go up and is planned to dock at the rear port of the Tianhe core module.

“Tianzhou-7” mission ship and rocket combination

In this mission, Tianzhou-8 will carry lunar soil bricks to the Chinese space station for the first time. Lunar soil bricks are made by firing simulated lunar soil on the ground. They are much harder than ordinary concrete and may be used to build lunar structures in the future. In order to verify whether the lunar soil bricks can withstand the test of extreme environments, they will undergo exposure tests in the space station.

The Tianzhou series cargo spacecraft is the first type of professional cargo spacecraft developed by China. It is developed based on the technical foundation of the Tiangong series space laboratory and the Shenzhou series manned spacecraft. It has a high starting point and is a disposable spacecraft. The Tianzhou-8 is an improved version of the Tianzhou series cargo spacecraft and the third spacecraft in the second batch of products after the mass production of the Tianzhou series cargo spacecraft.

The spacecraft adopts a dual-cabin tandem configuration, with the propulsion cabin and the cargo cabin from bottom to top in the launch state. The spacecraft is 10.6 meters long, with a maximum diameter of the main body (cargo cabin) of 3.35 meters, a wingspan of 14.9 meters when the solar wing is unfolded, a cargo cabin loading space of 22.5 cubic meters, a loading capacity of 6.7 tons, a total cargo loading capacity of 7.4 tons, a spacecraft dry mass of 6.5 tons, and a cargo-to-load ratio of 0.53. The “Tianzhou” spacecraft is the world’s most powerful cargo spacecraft in service, with the highest cargo-to-load ratio and the most comprehensive on-orbit support capability.

Tianzhou-7 cargo spacecraft

At present, the Tianzhou series of spacecraft have the ability to quickly rendezvous and dock with multiple options, and can choose to go uphill in 6 hours, 3 hours, 2 hours and other options, which has been an early application for speeding up the uphill mission of the Shenzhou series of spacecraft.

Since the implementation of the Chinese space station mission, the launch frequency of the Tianzhou cargo spacecraft has been adjusted from twice a year to three times every two years, and the launch density will be further reduced. When the Tianzhou-8 is launched, the interval between the launch of the Tianzhou-7 will reach 10 months, which will set a record for the longest launch interval of the Tianzhou cargo spacecraft.
