In his presentation Tuesday, Lerch highlighted the cost-effectiveness of the Long March 5 rocket, the type of launcher used for Friday's launch with Yaogan-41. Although the rocket is an expendable design, Lerch said the marginal cost to launch a kilogram of payload mass on a Long March 5 is $3,000.


"The Long March 9, which they are hoping to leverage reusable technology towards the turn of the decade, when that’s operational, they’re hoping to shave that in half to about $1,500 per kilogram," Lerch said. "The Chinese are going that route ... and they’re going to get there with different types of fuel and also through reusability.”

Interesting comment from the US space force officer on what they think the price of a LM5 is and what they expect of the LM9. That's around the price of Falcon 9 for an expendable rocket.

why american journos are so shure they can hide their carriers to mighty chinese missiles? They always say that they can break the kill chain... Good luck with these things in GEO

Those satellites are big, fat, juicy targets in a war. SSF need to be resilient and have strong counterspace capabilities to credibly deter and counter US Space Force.

Once China gets it's own megaconstellations of tens of thousands of satellites in LEO that can basically cover the entire globe 24/7, it will be a game changer. There's will be no issues with targeting or kill chains and there's no way to shoot all those sats down in any reasonable amount of time

as far as i know no one ever tested to bring down a geo satellite

A team from the municipal government of Ningbo visited the Hainan Commercial Spaceport to learn from its experience. Ningbo declared its intentions to build a spaceport back in 2021, so it appears the project is moving along.

Ningbo Spaceport will occupy an area of 67 square kilometers, of which 35 will be for the launch site, and the rest will be for various support infrastructure. The spaceport will be capable of 100 launches annually.

Earlier bid announcements for the construction of a rocket assembly building and launch command center, totalling 4500 square meters.

Another private space company. AZSpace, also known as Ziwei Technology (紫微科技), is based in Wuxi and develops commercial cargo spacecrafts. Its B300 commercial cargo ship is scheduled for launch in June, 2023. I'm not sure what rocket will launch it.

An update on AZSpace, also known as Ziwei Technology (紫微科技). The company's technology verification cargo spacecraft Dier-1 (迪迩一号) has been transferred to the Jiuquan launch center. The launch will be carried out by a Hyperbola-1 rocket from i-Space/Space Honor/Interstellar Glory.

DeepBlue's reusable Thunder-R1 LOX/kerosene engine has successfully completed its first long-duration (single ignition) hot test, with the test lasting 420 seconds (over twice the expected flight time of the 1st stage of the Nebua-1 rocket). The cumulative test run time on the engine has now reached 2,000 seconds.

DeepBlue's reusable Thunder-R1 LOX/kerosene engine has accumulated 130 test runs and is now deemed mature. Next year, the company will conduct a high-altitude VTVL test of the first stage of its Nebula-1 rocket.
