By the goals achieved, it reminds me somehow the first missions in the KSP video game.
Neat! But since this is a solid rocket, I presume that this company is a fairly thin cover for a company (or state owned entity) serving the Chinese defense industry. Large scale solid rockets at this scale is not something that a startup company would normally be capable of. But if I'm wrong, more kudos to them!

Several people are linking Stage 1 parameters most closely fit DF-10/11/15 missile families which are being phased out of the missile reserve fleet in favor of newer missile systems that have/are come/coming online.

This - and what we (don't) see in their videos - does make it seem like this is a shell company that here to show that "we have new space companies too!". The videos show a distinct lack of production facilities. An empty warehouse with a huge sign blocking the empty area does not inspire confidence,
At 7:33 on May 17th, at the launching base in northwest China, the "Chongqing Liangjiang Star", an OS-X rocket independently developed by the Chinese private company OneSpace, was successfully launched."Chongqing Liangjiang Star" is the first type of rocket in the OS-X series of the OneSpace, and is also the first privately-run commercial suborbital rocket in China. The rocket is 9 meters long and weighs 7,200 kilograms. Yesterday, after being lifted off, it flew in the atmosphere. The maximum altitude was about 38.7 kilometers, the maximum speed was over 5.7 times the speed of sound, the flight time was 306 seconds, and the flight distance was 273 kilometers. ! ! ! Please see this video belowIn addition to verifying the performance of the X-Series rockets, the first flight also scored three achievements: First, to complete research objectives, such as verification of drag reduction and heat reduction of pneumatic support rods, to provide technical reserves for future product layout design; The second is the verification test window, such as the test maximum height (40 km), Mach number (4-6 Mach), etc. The third is to verify the cooperation model, for example, universities put forward cutting-edge scientific issues, through the first flight to carry out practical verification.OneSpace X-Series Flight Test Platform adopts a self-developed commercial solid rocket engine as its power. Its engine thrust reaches 350KN. It has a powerful carrying capacity and can achieve a flight speed of 0-20 Mach for the customer's load. The test platform can be carried out according to the needs of users. Custom design to meet the needs of users. The platform adopts a modular design, low cost, high reliability, and provides a full-process launch service that is convenient and quick to launch.OneSpace is the first domestic private company with complete intellectual property rights such as complete rocket R&D, design, production, final assembly, etc. It is also the first domestic private company to complete self-research rocket launch. The successful launch of "Chongqing Liangjiang Star" is a milestone event that marks an important step in the field of private aerospace. In the Chinese aerospace field, there is a new pattern of mutual promotion and complementarity between the "national team" and private enterprises.Onespace has changed in the past by relying on state investment to research and develop aerospace-grade products, pioneering the introduction of advantageous social capital and large-scale state-owned industrial investment groups in the field of rocket development, sharing interests through equity investment, and sharing risks. Since its establishment in Beijing in 2015, in the three years it has accumulated three rounds of financing with a total amount of nearly 500 million yuan.OneSpace actively responds to the national military-military integration strategy. Based on its mature technology, it has independently developed the OS-X series of sub-orbital rockets. Together with Beihang, China Southern Airlines, Xigong University and Harbin Institute of Technology, more than 10 domestic traditional aerospace advantage universities have jointly established a flying alliance. Through low-cost, high-frequency and combined flight tests, the threshold for technical verification is reduced, and the effective conversion of airspace technology is accelerated, thereby enriching the country's mature technology reserves in the airspace sector. The Flying Alliance is an open, innovative, and shared platform. By 2020, it will achieve “three hundred” and the number of alliance members will reach 100. The X-Series rockets will complete one hundred scientific research missions each year. Technical verification funds are within one million.The future goal of OneSpace is to unite closely with universities and research institutes, and build a closed-loop aerospace science and technology ecological chain from research needs to flight verification, from program design to achievement hardening, and lead the nation through serialized flight tests. The development direction of airspace technology has gradually increased the research level of basic science in the national aerospace field and rapidly promoted the application of cutting-edge technology. At the same time, the company's own research and development of the OS-M series rockets will focus on micro-satellite precision and rapid networking launches, serving global small satellites and related business needs customers, providing fast, low-cost and high-quality launch services, its first type of rocket program will The first flight took place before and after the end of this year. OneSpace will work together with the national team to coordinate and cooperate with each other and make contributions to building China from a space power country to a space power nation.
Does the "pneumatic support rod" thing mean the aerospike on the top? An uncommon feature among rockets like this. Doesn't look like deployable. And those fins look odd, almost like some after thought. Chinese rocket designers like fins a lot, even the new CZ-5 and CZ-7 has fins.
Vestiges of reusing military components, particular the nosecone/RV design? But if a DF-10/11/15 derivative, those are all land based missiles, which doesn't explain the aerospike. Interstage/nosecone perhaps from a SLBM?

OS-X seriesThe OS-X series of rockets are suborbital sounding rockets, reaching high altitude or reaching space but not orbit; they are meant for research and development of their launch systems.OS-X0The OS-X0 (aka "Chongqing Liangjiang Star")[9] is a 9 m (30 ft) long suborbital high-altitude rocket. It uses solid propellant and is designed to carry payloads up to 100 km (62 mi) reaching space. First flight (suborbital) was on 16 May 2018, reaching an altitude of 40 km (25 mi).[7][10][11] The rocket is built completely from homegrown Chinese technology.[7] Its launch represents the first rocket designed by a private company launched in China.[9]OS-X1The OS-X1 is a suborbital high-altitude rocket, a sounding rocket, designed for research and testing.[6] The solid rocket motor was successfully tested in December 2017, in anticipation of a rocket launch in June 2018.[12]OS-M seriesThe OS-M series of rockets are larger than the OS series and aim to provide low cost flights to LEO and SSO.[13]OS-M1The OS-M1 is a light-launch spacelaunch launch vehicle rocketing payloads to low Earth orbit (LEO) and Sun synchronous orbit (SSO). It is projected to be capable of lofting 205 kg (452 lb) to 300 km (190 mi) high LEO; and 73 kg (161 lb) to 800 km (500 mi) high SSO.[6][13][14] The first launch is scheduled for Q4 2018.[15]OS-M2The OS-M2 is similar to the OS-M1, but has two boosters. Block A will be capable of lifting 390 kg (860 lb) to LEO and 204 kg (450 lb) to 800 km (500 mi) SSO, while block B will be capable of lifting 505 kg (1,113 lb) to LEO and 274 kg (604 lb) to 800 km (500 mi) SEO.[16]OS-M4The OS-M4 has four boosters. Block A will be capable of lifting 552 kg to LEO and 307 kg to 800km SSO, while block B will be capable of lifting 748 kg to LEO and 446 kg to 800km SEO.[17]Future OS-M rocketsThe firm is anticipating making future entries in the OS-M series of rockets in some way reusable.[6]OneSpace is developing a 59 ton rocket,[5] that was originally scheduled for launch in 2018. It is to have a 500 kg (1,100 lb) payload to LEO. This is projected to cost RMB ¥100,000 CNY/kg ($6500 USD/lb)[18] OneSpace also envisions to eventually develop a crewed space capsule.[18]https://en.wikipedia.org/wiki/OneSpacehttp://www.onespacechina.com/
So it is a sensor probe instead of aerospike? Then what "verification of drag reduction and heat reduction of pneumatic support rods" refers to? Those yellow things below?In China, state owned is better than privately owned, and directly owned by the central government is way better than state owned. Supported/backed by some big name state ministry, or even some tenuous connection to the state gives a private enterprise credibility. Some products even spend big money to run their marketing campaign at Great Hall of the People. So I take "SASTIND helped found us" with a grain of salt.
Now I am total lost on the "pneumatic support rods". Could be anything.Found a few images of Df-15 tails. Looks quite different. Those fins are removable, and separated from the TV assembly. OS-X0 images are too small to see details, eps TV vanes. Those fins are a lot smaller, not attached to the aft skirt as they usually do, but attached to some extension from the skirt. And skirt is a lot wider than the body. As if they want to move center of pressure as backward as possible, but refuse to use bigger fins.
