#SpacePioneer seems to be the next Chinese commercial company to attempt a liquid-fueled launch.
A singular feature of their Tianlong-2 rocket is that it can launch from any flat concrete surface: a TEL transports & erects the rocket, and tanker trucks provide propellant on-site.
While this is unique among Chinese liquid-fueled rockets, it's worth noting that other companies outside of China are also testing this concept. For example, here's a diagram from @ablspacesystems' RS1 launch vehicle user guide where a TEL and tanker trucks are also employed.
Space Pioneer claims this reduces complexity, increases flexibility & reduces costs.
In late 2020 during a presentation, their CEO took a jab at @LANDSPACE_China, saying that their launch infrastructure in Jiuquan cost >1B RMB.

As noted by @CNSpaceflight, an oxygen tanker truck can be spotted on the footage of Space Pioneer's latest launch rehearsal.
#Landspace is going to attempt the launch of the ZQ-2 rocket (aka Zhuque-2). This is China’s 1st liquid-fueled commercial rocket, one of the first methalox-fueled rockets globally, and this could be a turning point for Chinese launch.
Let's recap the situation in a thread 🧵
First, some context: At least 15+ commercial launch companies have been formed since 2014.
Although this seems like a excessive number, a consolidation has not taken place (yet) as most companies are still early stage and supported by VC money & local governments.
Regarding actual commercial launch capacity, we’re starting to see regular launches of solid-fueled rockets. There are no less than 7 rockets at the moment: The Kuaizhou-1A & 11, Jielong-1 & 3, Lijian-1, Ceres-1 and the Hyperbola 1.
3 of the 7 were put into service in 2022 alone.
Really insightful interview with the Co-Founders of Chinese asteroid mining and space debris mitigation company Origin Space, alumni of Harvard PhD and NASA fellowships respectively, Su Meng and Yu Tianhong. A short 🧵🇨🇳🚀☄️
Origin Space calls themselves the first and only space resource mining company in China. The company has launched 3x spacecraft and 2x telescopic payloads, including NEO-01 spacecraft and the Zhangwang-1 space telescope, both of which are surveying for suitable asteroids
(2/4)
Co-Founder Su Meng describes two ways of asteroid mining:
1⃣️ Do the mining at the asteroid in limited/near-zero gravity
2⃣️ Bring the asteroid back near earth and mine from there.
Origin Space plans a Type 2⃣️mission in 2025 to bring an ☄️ back to 🌍 for mining
Starting a quick thread to track the different engines on the #Tianhe-1 module of the CSS (feel free to comment if smth. is missing!)
Let's first start with the fact that Tianhe-1 is equipped with 30 thrusters, of which 26 are chemical thrusters, and 4 are Hall Effect thrusters.
Most thrusters are situated on the non-pressurized propulsion compartment at the very back of the Tianhe-1: a compartment that has a diameter of 4.2m & a height of 2.1m. This area is literally full of propellant! Its dry mass is 487 kg, but weighs 4.3 tons once fueled up...
Among these 26 thrusters, 4 are larger orbital control thrusters, which are very visible on pictures. They have an angle of inclinaison with the axis of the Tianhe-1, presumably to avoid having the thrust affect the core module exterior wall.
