The launch schedule of home personal business rockets continues to be up to date.
Exclusive data obtained by a reporter from Science and Technology Innovation Board Daily reveals that the “Gravity-2”, a medium-to-large liquid recoverable launch car independently developed by Dongfang Space, a number one home business area rocket enterprise, is predicted to finish its maiden flight in mid-2026.
In addition, Dongfang Space confirmed to the reporter from Science and Technology Innovation Board Daily that this rocket, which is designed to fulfill the large-scale networking wants of medium-to-large satellites and business high-orbit launch necessities, is supplied with an revolutionary core stage restoration design.
01
The so-called “core stage recovery” isn’t a brand-new idea. In the engineering context of launch automobiles, it often refers to the design of returning and reusing the first stage of the rocket – the core stage that bears the primary thrust, structural load, and gas consumption.
In China, some business area corporations have beforehand tried to conduct precise flight verification of this expertise path. For instance, Landspace’s Zhuque-3 liquid oxygen methane rocket has carried out a real-flight take a look at of the first-stage restoration course of throughout its maiden flight mission. Although profitable restoration has not been achieved but, related engineering verification has been initiated.
On this foundation, Dongfang Space’s choice to introduce core stage restoration design in its medium-to-large liquid launch car, the “Gravity-2”, holds significance on two fronts: Firstly, it represents an important technological improve for the firm because it transitions from the stable rocket system to the liquid and reusable rocket system. Secondly, it additionally signifies that the home business area trade is starting to discover whether or not core stage restoration has possible engineering and price worth underneath the necessities of larger payload capability and extra advanced missions.
It is known that the core stage restoration expertise of the “Gravity-2” isn’t a easy replication however a custom-made innovation based mostly on the wants of the business area trade. Firstly, in phrases of structural reuse energy, through the use of light-weight and high-strength alloy supplies and modular design, the rocket physique may be reused at least 30 instances. Secondly, in phrases of fast turnaround functionality, counting on the pulse remaining meeting line at the manufacturing base in Tai’an, Shandong, and distant distributed complete testing expertise, the recovered core stage may be rapidly inspected and maintained inside 48 hours after which be prepared for an additional launch, supporting the high-density launch requirement of “one rocket per week”.

Why is core stage restoration so necessary? In the previous two years, with the large-scale networking of low-orbit communication satellite tv for pc constellations, the demand for batch satellite tv for pc launches has grow to be pressing. Reusable rockets are extra appropriate for this high-density launch situation.
In phrases of price, the engine and rocket physique construction account for the majority of the price in rocket manufacturing. Recovery and reuse can considerably scale back the price of a single launch. SpaceX’s observe has confirmed that by way of restoration and reuse, the price of every launch of the Falcon 9 rocket has been lowered by roughly 20 – 30%.
In the worldwide enviornment, SpaceX is the front-runner on this area. Its Falcon 9 rocket has achieved over 200 recoveries and over 180 reuse flights, turning restoration from an “experiment” right into a “routine operation”. Blue Origin’s New Shepard suborbital rocket has additionally achieved a number of profitable recoveries, and its New Glenn orbital rocket can also be focusing on restoration and reuse. In addition, Europe, Russia, India, and many others. are additionally advancing related plans.
China is accelerating its pursuit in the area of reusable rockets.
Among the “national teams”, each the China Aerospace Science and Technology Corporation and the China Aerospace Science and Industry Corporation have initiated the improvement of reusable launch automobiles and introduced some mannequin plans.
Among business area corporations, along with Dongfang Space, Chinese business rocket corporations equivalent to Landspace and GalaxySpace have additionally listed reusable rockets as key analysis and improvement instructions, forming a sample the place each the “national team” and the “private team” are collectively selling the improvement.
At the 2026 Beijing International Commercial Space Forum, Li Jun, the chief engineer of GalaxySpace, revealed that GalaxySpace’s liquid restoration rocket, the Pallas-2, is predicted to make its maiden flight in 2026. The Pallas-2 is a big modular reusable liquid launch car with a diameter of 4.5 meters, together with two configurations: the fundamental kind and the CBC kind. The fundamental kind has a takeoff mass of roughly 757 tons, a takeoff thrust of roughly 910 tons, and a LEO payload capability of 20 tons. The CBC configuration has a takeoff mass of roughly 1950 tons, a takeoff thrust of roughly 2730 tons, and a LEO payload capability of 58 tons.
However, core stage restoration isn’t with out challenges. An engineer in the business area area analyzed to the reporter from Science and Technology Innovation Board Daily that in phrases of technical reliability, rocket restoration locations extraordinarily excessive necessities on steering and management, engine thrust adjustment, and structural energy. The price of inspection, upkeep, and refurbishment after restoration must be strictly managed to attain actual “cost-effectiveness”. Some high-value payload clients nonetheless have doubts about the security of reusable rockets, and it’ll take time and profitable information to construct belief.
From an total trade perspective, there’s a rising divergence amongst home business area enterprises of their understanding of “core stage recovery”.
Some producers view core stage restoration extra as a prerequisite for supporting high-frequency low-earth orbit launches, with the core goal of bettering turnaround effectivity and lowering the marginal price of a single launch. Other producers are extra involved about whether or not the restoration mechanism nonetheless has financial significance in the context of larger payload capability and extra advanced mission eventualities.
The “Gravity-2” represents the latter method. For Dongfang Space, the core stage restoration of the “Gravity-2” is extra like an important step in filling a key functionality hole throughout the product’s generational leap. It not solely signifies the firm’s entry into the deep finish of the expertise pool of liquid reusable launch automobiles from the stable rocket system but in addition determines whether or not it could possibly type a sustainable aggressive mixture in phrases of payload capability, price construction, and mission adaptability in the medium-to-large business launch market in the future.
