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.

That was quick. Dier-1 (迪迩一号) has been launched using a Hyperbola-1 rocket from i-Space/Interstellar Glory. Dier-1 is a technology demonstrator and will pave the way for AZSpace/Ziwei's B300 unmanned cargo spacecraft.

An update on the AZSpace/Ziwei's Dier-1 technology demonstrator cargo craft. Dier-1 has been operating smoothly since launch and has met all performance expectations. The valuable data collected from this mission will pave the way for the upcoming B300 unmanned cargo spacecraft.

They clearly need to increase the amount of LM-7 launches. And put the LM-10 in service.
They should also convert at least one of the inland launch sites to the LM-7. I am surprised we haven't seen moves towards this yet.

I don't think that will happen this decade. Why should they when they are already happy with the increase launch rates of the older more mature hypogolic rockets like long March 2, 4, etc?

There's lots of other secondary benefits to developing some specific types of technology. For obvious reasons, learning to get good at burning jet fuel and oxygen in a internal combustion engine might benefit other types of technology more then the tiny uses of hypergolic fuel. There's a reason why countries that are good at cryogenic rockets also tend to have good jet engines or vice versa. That' billions every year going into 40 year old rocket engine designs instead of learning how to make better modern engines.

And then there's learning how to handle cryogenic fuels, rocket ignition, dealing with boil-off and other stuff that you don't have to deal with hypergolic rockets. You don't push for the cutting edge, you will fall behind. And cryogenic rockets give better performance anyway.

Two Dalian-1 12U remote-sensing cubesats hitched a ride with the Tianzhou-6 spacecraft. They are developed by Dalian university for the province of Liaoning. Each cubesat weighs 17kg, and they will be used to verify various technologies that include new hyperspectral imaging cameras, the use of OpenHarmony OS for space applications, a domestically developed processor for space applications, a compact propulsion system using hydroxylamine nitrate propellant, an new ultra-light multiple-satellite deployer (UMSD) etc. The satellites are mounted on the UMSD attached to the outside of the Tianzhou-6 spacecraft and will be released in the coming days.

A Dalian-1 Lianli (大连1号—连理卫星) CubeSat has been successfully released by Tianzhou-6 cargo spacecraft. It is now operating normally. The satellite had been stored externally on the spacecraft for 253 days prior to its deployment, and it will be used to test a number of technologies that include new hyperspectral imaging cameras, the use of OpenHarmony OS for space applications, a domestically developed processor for space applications, a compact propulsion system using hydroxylamine nitrate propellant, etc. The successful release of the satellite also validated the design of the ultra-light multiple-satellite deployer (UMSD).

Because they are a disaster waiting to happen. Everyone has been moving away from hypergolics for space launches.

Hmmm....well, i believe the administrators know better than us what's best suits them. So if they have been using more and more hypergolics instead of the few newer cryogenic rockets they have in store then it means they believe their needs are better served by using the older more mature Hypergolics rockets. At the end of the day, the end justifies the means I guess. We can whine all we want on here but they will do what they think best suits their needs for now.

Well, private players can take the risk to involve themselves in those new cryogenic reusable rockets designs, we dont know if they can even pull it off and the risks and time involve to make them mature and reliable. Many will probably go bankrupt after trying their hands on those and having failed launches and investors backing off. SOE value stability and maturity. No need to start getting involve in unproven technology and adopting them on mass scales
