A new private launch startup CosmoLeap tests chopstick recovery.

CosmoLeap has recently conducted hot test runs of the 100-Newton and 300-Newton engines intended for the auxiliary propulsion system of the Leap-1 launch vehicle.

More information on Cosmoleap's Leap-1 reusable launch vehicle:
– Diameter: 4.2m
– Length: 70m
– Take-off mass: 554 tons
– Take-off thrust: 720 tons
– Capacity to LEO (single-use, reusable): 18 tons, 12 tons

On March 28, the first Academy（China Academy of Launch Vehicle Technology） developed 5-meter-diameter stainless steel propellant tank, designed and manufactured by the First Academy, was officially rolled off the production line, providing support for the smooth progress of a major mission. The project team completed the design and manufacturing in just 60 days, significantly improving development efficiency.

I wonder which rocket this is for. Might be for the Long March 10, but the news would have mentioned it. There have been some rumblings about a reusable rocket from CASC with a diameter of 5m that's set to debut in late 2027, but all the information I could find doesn't mention a specific model. For all I know, it could be the reusable version of Long March 10 that we know is being actively developed.

The new propellant tank is unlikely to be intended for the Long March 10A.

1. The Long March 10A will aim to use as many common components as possible with the Long March 10, including the propellant tank.
2. I measured the image, and the new propellant tank is approximately 12.86 meters long. Based on calculations, it can store about 287.7 tons of liquid oxygen. This amount is roughly equivalent to that of the Falcon 9. However, the Long March 10A has a liftoff mass of about 750 tons, significantly greater than the Falcon 9’s 550 tons. Its first-stage rocket requires more than 380 tons of liquid oxygen, which far exceeds the capacity of the new propellant tank. I believe the new propellant tank is very likely designed for the rumored 5-meter-diameter reusable rocket that uses 12 YF-209 engines.

10 will use Ai-Li and the latest friction-stir welding techniques to minimize dry mass and maximize performance to translunar injection. it is a very purpose-built vehicle. It will also share tooling with 5.
Stainless steel, unless a super-light weight balloon tank construction (like the US Centaur - which is an upper stage) is not very good for expendable designs. Too much parasitic mass.

10 will use Ai-Li

I think you meant Al-Li, no?

At 00:05 Beijing Time on March 30, China successfully launched the Communication Technology Test Satellite No. 16 using a Long March 7A carrier rocket from the Wenchang Spacecraft Launch Site. The satellite entered its predetermined orbit, marking the complete success of the mission.

The images are from video footage captured by rocket enthusiasts, though the exposure seems to have been cranked up too high.
