China launches first Lengthy March 6C rocket

HELSINKI — The brand new Lengthy March 6C rocket efficiently inserted 4 satellites into orbit late Monday on its debut flight.

The primary Lengthy March 6C rocket lifted off from Taiyuan Satellite tv for pc Launch Heart, north China, at 11:21 Japanese, Might 6 (0321 UTC on Might 7). The Shanghai Academy of Spaceflight Know-how (SAST), the rocket’s producer, confirmed launch success inside an hour of liftoff. 

4 satellites have been aboard the launch. The primary payload was Haiwangxing-1, or Neptune-1, an experimental, 239-kilogram X-band artificial aperture radar satellite tv for pc. Neptune-1 was manufactured by SAST for Zhihui House Tech. The latter agency goals to launch 12 operational satellites for the Neptune constellation.

The opposite satellites included Zhixing 1C, one other SAR satellite tv for pc, this time for Beijing-based Good Satellite tv for pc. The opposite two are described as wide-view optical and high-resolution video satellites. The mission was a SAST rideshare launch.

The brand new, 43-meter-tall rocket is the most recent in a line of new-generation rockets developed by SAST designated within the Lengthy March 6 sequence. 

The Lengthy March 6C seems as a shorter variant of the 50-meter-tall Lengthy March 6A with out the latter’s 4 strong rocket boosters. The rocket is able to lifting about 2,400 kgs to a 500-kilometer Solar-synchronous orbit (SSO). The 6A can carry 4,500 kg to a 700-km SSO. The variants present better launch choices and suppleness.

The launch was China’s twentieth of 2024 and follows the Might 3 launch of the Chang’e-6 pattern return mission. China goals to launch round 100 instances this yr.

SAST’s new rockets

The Lengthy March 6C will not be the one new SAST rocket anticipated to fly this yr. The academy can be planning to debut its 3.8m-diameter Lengthy March 12 later this yr from a brand new industrial launch web site at Wenchang. Will probably be able to lifting 10 tons to low Earth orbit or 6 tons to a 700-kilometer sun-synchronous orbit. 

The rockets are a part of a brand new era of Chinese language rockets that use kerosene and liquid oxygen as a substitute of poisonous, hypergolic propellant. Nonetheless, entry to spaceports able to facilitating these launches has slowed the speed at which the older Lengthy March rockets might be changed.

There are better, but extra nebulous plans past the above. The academy goals to debut a 4.0-meter-diameter rocket within the subsequent couple of years. It might use methane-liquid oxygen engines developed by a industrial entity.

A SAST promotional video launched with at the moment’s launch reveals the Lengthy March 6A and 6C subsequent to 2 additional rocket fashions. Each future fashions seem to have touchdown legs for restoration and reuse. It’s unclear which rockets these are. 

SAST is a significant institute underneath the China Aerospace Science and Know-how Company (CASC), the nation’s state-owned major area contractor. 

Beijing-based China Academy of Launch Automobile Know-how (CALT) is CASC’s different rocket design and manufacturing arm. CALT is growing the brand new Lengthy March 10 reusable rocket for human spaceflight. One variant of which shall be designed to ship astronauts and a touchdown stack to the moon. The Lengthy March 10 shall be slowed by retropropulsion and caught by tight wires when in recoverable mode.

Industrial reusability in China

China’s efforts to develop reusable rockets don’t cease there. The nation’s industrial launch service suppliers are additionally engaged on reusable launchers. These notably embody House Pioneer’s Tianlong-3, which shall be comparable in capability to the Falcon 9 and on account of launch later in the summertime. Landspace is engaged on its Zhuque-3 chrome steel rocket at Jiuquan, whereas iSpace can be growing a methane-liquid oxygen Hyperbola-3 rocket. Various these firms have additionally performed hop assessments, together with SAST and CASC’s sister entity CASIC.

The primary orbital launch and touchdown try could nonetheless come from Deep Blue Aerospace. The agency plans to launch its light-lift Nebula-1 rocket within the second half of the yr. Galactic Power can be working in the direction of the primary launch of the Pallas-1 kerosene-liquid oxygen rocket. The primary flight, anticipated later this yr, is more likely to be expendable.

Firm	Rocket Identify	Rocket Sort	Key Options or Notes
iSpace	Hyperbola-3	Methane-liquid oxygen reusable	Payload capability of 8,500 kg to Low Earth Orbit (LEO); first flight deliberate for 2025.
Landspace	Zhuque-3	Methalox reusable	Payload capability as much as 21,000 kg to LEO; first flight deliberate for 2025.
Galactic Power	Pallas-1	Kerosene-liquid oxygen reusable	Payload capability of 5,000 kg to LEO, or 3,000 kg to a 700 km sun-synchronous orbit (SSO).
CAS House	Kinetica 2	Kerolox reusable	Payload capability of seven,800 kg to 500 km SSO.
Deep Blue Aerospace	Nebula-1	Kerolox reusable	Payload capability of 1,000 kg to 500 km SSO; first flight deliberate in late 2024.
House Pioneer	Tianlong-3	Kerolox	Corresponding to Falcon 9 in launch functionality; plans for a reusable first stage.
Orienspace	Gravity-2	Kerolox	25,600 kg to LEO. First flight in 2025; plans for a reusable first stage.
CASC	Numerous	Numerous	Engaged on reusable rockets together with a new-generation human-rated launcher, spaceplane, and Lengthy March 9 tremendous heavy-lift launcher.
