Summary

Orienspace (Oriental Space / Dongfang Space), founded in 2020 in Yantai, builds the Gravity (Yinli) family of launch vehicles. Its solid-propellant Gravity-1 is the world's largest and most powerful solid-fuel carrier rocket - sea-launched and capable of 6,500 kg to LEO - with three successful flights: January 2024 maiden and October 2025 second from a barge off Haiyang, and a third flight on July 22, 2026 that was its first fully commercial mission and China's first far-sea commercial rocket launch, lifting off from a service ship in the East China Sea off Shanghai and deploying nine satellites, including six Dongpo satellites for the Huantian constellation. The company is now developing Gravity-2, a roughly 70-meter, partially reusable kerosene-liquid oxygen heavy-lift rocket powered by nine in-house Yuanli-110 engines and sized at over 20 tonnes to LEO; after schedule slips, Orienspace expects the debut flight in Q4 2026, with the triple-core Gravity-3 to follow in 2027. Orienspace raised an $83.5M Series B in January 2024, added a Series B+ round in August 2025 valuing it at roughly $823M-960M (6-7B yuan), and on August 5, 2026 closed a pre-C round worth several hundred million yuan from investors including Vertex Capital, Shanghai STVC, AVIC Honghua and Yuanyou Ruize, earmarked for Gravity-2 development, while beginning IPO coaching procedures toward a planned Shanghai STAR Market listing.

Gravity-2 (Yinli-2)

In Development

Two-stage, partially reusable kerosene-liquid oxygen heavy-lift rocket with a vertically landing first stage powered by nine in-house Yuanli-110 engines - Orienspace's higher-than-Falcon-9-class vehicle.

The Yuanli-110 engine completed its first test firing in September 2025 and a nozzle-less restart test in November 2025; by July 2026 it had completed multiple full-system test firings. Orienspace expects Gravity-2 to be ready for its debut flight in Q4 2026 (a slip from earlier targets), with initial flights potentially using YF-102 engines while Yuanli-110 matures.

What's Next

Gravity-2 first flight and engine qualification

Complete Yuanli-110 engine and stage testing and fly the reusable kerolox Gravity-2 for the first time. As of August 22, 2026 the Yuanli-110 has completed multiple full-system test firings and Orienspace expects the vehicle to be ready for its debut flight in Q4 2026 (initial flights may use YF-102 engines while Yuanli-110 matures); no new engine test or schedule change has been reported since the July 2026 hot-fire milestone.

Q4 2026

Scale Gravity-1 launch cadence

Having flown the third Gravity-1 successfully on July 22, 2026 - a far-sea launch from waters off Shanghai deploying nine satellites (six for the Huantian constellation) after a nine-month gap - Orienspace has said it plans three more Gravity-1 batch launches before the end of 2026, one of which is expected to deploy for a satellite-internet mega-constellation (Guowang/Qianfan). In early August 2026 hardware for the fourth flight was moved to Orienspace's vehicle integration site at the Haiyang Oriental Spaceport, with the company targeting a Q3 2026 (July-September) launch window and moving toward concurrent vehicle production to sustain the cadence; as of August 22, 2026 the fourth flight has not yet occurred.

2026

Demonstrate first-stage recovery and develop Gravity-3

Recover and reuse the Gravity-2 first stage to validate the reusable architecture, then advance the even larger triple-core Gravity-3 - targeted to fly in 2027 - for mega-constellation and lunar missions. As of August 22, 2026, Gravity-2 remains in pre-flight ground testing (first-stage and engine hot-fire tests completed) and has not yet flown, so no recovery attempt has been made.

2027-2028

Close Series C and advance toward a Shanghai STAR Market IPO

Following the several-hundred-million-yuan pre-C round closed August 5, 2026, Orienspace has begun IPO coaching preparation work and is reported to be nearing a Series C close, with a shareholding restructuring targeted before the end of 2026 as groundwork for a planned listing on Shanghai's STAR Market - the same path being pursued by fellow Chinese commercial-launch peers LandSpace, CAS Space, Space Pioneer, and Galactic Energy. No Series C close or formal IPO filing had been announced as of August 22, 2026.

Late 2026 (shareholding restructuring); IPO coaching to follow

Operations & Revenue

StatusOperational

Gravity-1 is operational and remains the world's largest solid-fuel carrier rocket. After a nine-month hiatus following its October 2025 second flight, Gravity-1 flew its third mission - its first fully commercial flight and China's first far-sea commercial rocket launch - on July 22, 2026, from a service ship in the East China Sea off Shanghai, deploying nine satellites (six Dongpo satellites for the Huantian constellation plus three rideshare payloads). As of August 22, 2026, hardware for a fourth Gravity-1 flight remains at Orienspace's vehicle integration site at the Haiyang Oriental Spaceport and the fourth flight has not yet launched; the company is targeting a Q3 2026 launch and two further batch missions before year-end, one of which is expected to deploy for a satellite-internet mega-constellation. The reusable kerolox Gravity-2 is in development, with its Yuanli-110 engine having completed multiple full-system test firings; Orienspace expects Gravity-2 to be ready for its debut flight in Q4 2026, with the triple-core Gravity-3 to follow in 2027.

Timeline

2026Gravity-2 debut slips to end of 2026

An Orienspace official confirms the reusable kerolox Gravity-2 will now make its debut flight at the end of 2026 - a slip from earlier 2025/early-2026 targets - with the larger triple-core Gravity-3 to follow in 2027. The Yuanli-110 engine has completed initial and nozzle-less restart firings, and the company is targeting up to four Gravity-1 flights in 2026 on a quarterly cadence.

2026Establishes Shanghai subsidiary ahead of planned IPO

On June 23, 2026, Orienspace (Shandong) Technology wholly establishes a new subsidiary, Orienspace (Shanghai) Aerospace Technology, with 30M yuan in registered capital, in Minhang District, Shanghai - part of the run-up to a planned Shanghai STAR Market listing. Co-founder Peng Haomin, the company's actual controller and the technical lead behind most of its rocket-engine patents, is named legal representative of the new entity.

2026Gravity-1 completes first far-sea commercial launch

After a nine-month gap since its October 2025 second flight, Gravity-1 launched from a service ship in the East China Sea off Shanghai on July 22, 2026 (02:54 UTC) - its third flight, its first fully commercial mission, and China's first long-range/far-sea commercial rocket launch. The mission deployed nine satellites, including six Dongpo satellites (two optical, four SAR) for the Huantian constellation plus three rideshare payloads (Xiguang-2(01), Tianyi-49, Zidingxiang-3), a smaller batch than the roughly 30-satellite mission originally previewed for the flight.

2025Yuanli-110 engine tests

Orienspace completes the first proper test firing of its Yuanli-110 kerolox engine in September 2025 and, in November 2025, runs a nozzle-less Yuanli-110 test demonstrating clean autonomous start/restart and shutdown - a key step toward booster recovery on Gravity-2.

2025Gravity-1 second flight

On October 11, 2025, Gravity-1 flies successfully for a second time, placing a Jilin-1 satellite and test payloads into a 539 km low Earth orbit nearly two years after its debut.

2025Series B+ round and Gravity-2 test-flight push

In August 2025 Orienspace closes a Series B+ financing round earmarked mainly for follow-up development and mass production of the medium-lift, reusable Gravity-2, as it targets a first test flight of the rocket. The round adds to the more than $150M raised across earlier rounds plus the January 2024 Series B.

2024Gravity-1 maiden flight and $83.5M Series B

On January 11, 2024, Gravity-1 reaches orbit on its debut from a sea platform off Haiyang, deploying Yunyao-1 weather satellites and becoming the world's largest solid-fuel carrier rocket. That same month Orienspace closes an $83.5M (600M yuan) Series B to accelerate Gravity-2.

2023Raises over $150M across four rounds

By late 2023 Orienspace completes four financing rounds totaling more than $150M to fund Gravity-1 and develop the reusable Gravity-2.

2020Founded

Orienspace is founded in June 2020 in Yantai, Shandong, by a team including Bu Xiangwei and Peng Haomin to build large solid and reusable liquid launch vehicles for China's commercial market.

Blue Origin

Rockets

Blue Origin is a privately held aerospace company founded by Jeff Bezos that develops reusable launch vehicles, rocket engines, lunar landers, in-space mobility systems, and satellite communications infrastructure. Its current programs span the New Shepard suborbital system, the New Glenn heavy-lift rocket, the BE-4 engine family that also powers ULA's Vulcan, the Blue Moon lunar lander family, the Blue Ring spacecraft platform, and the TeraWave network. The FAA closed its NG-3 mishap investigation and lifted the New Glenn grounding on May 22, 2026 - pinning the BlueBird 7 deployment failure on a cryogenic leak that froze a hydraulic line - but six days later, on May 28, a New Glenn exploded during a hotfire at Cape Canaveral's LC-36, destroying the transporter-erector at Blue Origin's only New Glenn pad. CEO Dave Limp said the rocket will fly again before year-end via a hybrid horizontal-integration/crane-erect path that skips replacing the destroyed transporter-erector, with the propellant farm, a second flight-ready booster, and three upper stages intact; on July 24, 2026 NASA and Blue Origin agreed to conduct New Glenn second-stage (GS2) hot fire testing at Stennis Space Center's B-2 stand beginning this fall while LC-36 recovers, and NASA's Pegasus barge is due at Kennedy Space Center around August 10-12, 2026 to carry the completed GS2 to Stennis. The Blue Moon MK1 'Endurance' cargo lunar lander has completed thermal vacuum testing at NASA Johnson, but with New Glenn grounded its launch to the Moon has slipped from a fall-2026 target to early 2027. Separately, a February 2026 NASA Artemis architecture overhaul reassigned the crewed Blue Moon Mark 2 lander to compete with SpaceX's Starship for the program's first Moon landing (now targeted for Artemis IV, as soon as early 2028) following a 2027 crewed low-Earth-orbit docking test on the restructured Artemis III. In a landmark shift after 26 years of near-total self-funding (roughly $30B cumulative), Blue Origin raised about $10B at a $130B valuation in July 2026 - its first-ever outside round, led by Coatue (~$4B) with Jeff Bezos adding ~$2B - to bankroll Limp's target cadence of roughly 100 launches a year against an estimated ~$4.8B 2026 spend. The company broke ground on a new ~120,000-square-foot Cape Canaveral payload processing facility on August 31, 2026, and on September 1, 2026 NASA awarded it a $700M contract to build and deliver a Mars Telecommunications Orbiter - built on the Blue Ring platform - by December 31, 2028, extending Blue Origin's business beyond Earth-orbit launch and lunar landers into deep-space communications infrastructure.

Boeing

Boeing is one of the world's largest aerospace companies, spanning commercial airplanes, defense and space systems, and aftermarket services. The 2026 turnaround gathered pace through the first half of the year: 314 commercial deliveries in H1 2026 (its best first half since 2018), a Q2 net loss of $428M on $24.6B of revenue that nonetheless produced the company's first positive free cash flow quarter (+$631M) in over a year, and a record total backlog of $715B including more than 6,200 commercial aircraft. The 737 MAX line reached rate 47 per month in May 2026 and gained a fourth final-assembly line - the Everett 'North Line' - in July, with rate 52 targeted for early 2027. At the Farnborough Airshow (July 20-24, 2026) Boeing booked 170+ aircraft led by SMBC's 100-jet 737 MAX order, while the long-delayed 777X neared its certification finish line even as Emirates declined to accept the first 10-11 early-build 777-9s over their age and GE Aerospace temporarily paused GE9X engine shipments pending a durability fix. The FAA certified the 737 MAX 7 on August 3, 2026, clearing the smallest MAX variant after nearly a decade of review, and on August 10 Boeing agreed to sell its Wisk Aero, Insitu, and SkyGrid subsidiaries to Archer Aviation for a near-20% equity stake. July's delivery pace cooled to 53 aircraft (down 17% from June and now trailing Airbus by 51 aircraft year-to-date, 367 vs 418), and on August 21 Boeing's roughly 17,000 SPEEA-represented engineers and technicians rejected the tentative contract their own bargaining councils declined to endorse (64.3% and 71.9% against, respectively) and authorized a strike if no new deal is reached before the current contracts expire October 6. Boeing shares fell about 7.5% on the news, cutting market cap to roughly $170B (from ~$183B in mid-August). On August 26 the FAA finalized an airworthiness directive requiring inspections of certain 787 Dreamliners over shim gaps at lower side-of-body splice plates. Boeing remains one of the two central global commercial-jet manufacturers alongside Airbus, with its trajectory now hinging on sustaining the 737 ramp without reintroducing defects, closing out 737 MAX 10 certification, avoiding an engineers' strike, and steering the 777X's remaining ETOPS testing toward 2027 certification.

CAS Space (Zhongke Aerospace) is a 2018 commercial spinoff majority-owned by the Chinese Academy of Sciences, led by founder and chairman Yang Yiqiang - former chief commander of the state Long March 11 solid rocket. Headquartered in Guangzhou, it operates the solid-fuel Kinetica-1 (Lijian-1), one of China's most-flown commercial rockets with 15 launches and 14 successes since 2022 (carrying 110 satellites - the first Chinese commercial rocket to top 100), and has committed to a monthly Kinetica-1 cadence for the second half of 2026. In March 2026 it successfully debuted the medium-lift kerolox Kinetica-2 (Lijian-2), a three-core, nine-engine rocket; its second flight, carrying 18 Qianfan constellation satellites, slipped from a September target to October 2026, with the Y2 vehicle departing CAS Space's Guangzhou factory for Jiuquan on August 26, 2026. The company holds ~63% of China's private launch market by volume. CAS Space filed for a $607M IPO on the Shanghai STAR Market in April 2026 at a target valuation of ~15 billion yuan (~$2.1B); the Shanghai Stock Exchange accepted the application, and on June 29, 2026 CAS Space refreshed its prospectus, disclosing full-year 2025 revenue of ~277M yuan against a ~1.12B yuan net loss and setting a 2029 profitability target for the first time. The application has since cleared the exchange's listing-committee review, with final CSRC registration, share pricing, and a trading date still pending as of early August 2026. It is scaling output at a new Zhejiang 'super factory' and developing first-stage reusability via the in-house Kinecore-2 engine (110 tf), which completed a 620-second cumulative long-duration qualification test - including a 400-second single burn, a new stability record - on June 30, 2026, en route to a phased plan targeting full first-stage recovery by Kinetica-2's tenth flight around 2028.

China Aerospace Science and Technology Corporation (CASC) is the state-owned prime contractor for China's space program and the world's most prolific launch organization by missions flown. Wholly owned by the central government through SASAC and led by chairman Chen Mingbo, it develops and operates the Long March (Changzheng) rocket family - which flew its 661st cumulative mission on August 4, 2026, delivering a 23rd batch of GuoWang broadband satellites - along with the Shenzhou crewed spacecraft, Tianzhou cargo vehicles, the Tiangong space station, BeiDou navigation and GuoWang broadband satellites, the Chang'e lunar and Tianwen planetary probes, and China's strategic missiles. After a national-record 73 launches in 2025, CASC is targeting over 100 launches in 2026 amid an industry-wide national push toward ~140, debuted the partially reusable Long March 12B in June 2026, and saw its Tianwen-2 probe reach the quasi-moon asteroid Kamo'oalewa on July 6, 2026. On July 10, 2026 it made China the second nation ever to recover an orbital rocket first stage, when the new single-stick, partially reusable Long March 10B flew its maiden mission from Hainan and captured its booster in a sea-based net - a landmark step toward closing the reusability gap with SpaceX, with a reflight of the recovered booster still targeted before the end of 2026. That momentum was interrupted on August 10, 2026, when a Long March 7A broke apart shortly after liftoff and lost its satellite payload - only the vehicle's second failure ever - triggering an engine investigation that put a question mark over the timing of Chang'e 7; CASC kept other Long March variants flying through the investigation, with a Long March 5B launching an eighth GuoWang satellite batch on August 13, 2026, and on August 19, 2026 rolled the Chang'e-7 probe and its Long March 5 (Y14) rocket out to the Wenchang pad ahead of a planned August 24, 2026 launch, but the mission was then postponed by Typhoon Narra and, per an August 23 China Manned Space Agency statement, cannot fly within the 2026 window at all - multiple outlets report a possible slip into 2027 - with no root cause or formal fleet clearance yet announced for the 7A investigation either. CASC is also advancing the triple-core Long March 10 toward a crewed Moon landing before 2030: the Long March 10A's own orbital debut is separately reported to carry a lunar navigation satellite ahead of the uncrewed Mengzhou 1 capsule test, still targeted around September 2026 but flagged in one report as at risk of slipping into early 2027.

Cosmoleap logo

Cosmoleap

Rockets

Cosmoleap (大航跃迁), legally Dahang Yueqian Technology, is a Chinese launch startup founded in March 2024 by Chen Shuguang to build the Yueqian-1 ('Leap-1') - and notably is the first Chinese company to pursue a SpaceX Starship-style 'chopstick' tower-catch recovery instead of landing legs. The roughly 70 m-tall, 4.2 m-diameter, methane–liquid oxygen two-stage rocket is designed to lift about 18,000 kg to LEO when expended or ~12,000 kg with the first stage recovered, on a cluster of nine ~80-ton-class engines reusable up to 20 times. It initially flies the YF-209 engine sourced from CASC's Academy of Aerospace Liquid Propulsion Technology while developing its own 100-ton-class Qingyu-11 methalox engine (targeting ~150 t thrust, deep throttling, and up to 50 reuses); Qingyu-11 cleared a round of core-component tests (torch ignition, low-temperature and liquid-flow testing) in June 2026 and is moving toward full-system test firing. Cosmoleap raised roughly 100 million yuan (~$14M) in November 2024 and a 500 million yuan (~$73M) Series A in April 2026 - about 600 million yuan (~$84M) total - led by Qianhai Ark and Puhua Capital. On March 3, 2026 the company signed a strategic supply-chain cooperation agreement with Beijing Aerospace Guanghua Electronic Technology, becoming the first commercial rocket firm to partner with the state-linked aerospace-electronics supplier. With its design review passed and a tower-catch verification platform and drop tests underway, the company plans final assembly and integrated testing in the second half of 2026 and a debut orbital flight in 2027, racing domestic tower-catch rival Astronstone, which is pursuing a similar late-2026/early-2027 debut. Ground testing kept pace through mid-2026: the first-stage liquid-methane pressurization and delivery system passed China's first dedicated natural-circulation precooling test for a reusable methalox rocket in June, and the second-stage frame and propellant-tank rear-bottom structure passed a combined static-load test in August.

Deep Blue Aerospace logo

Deep Blue Aerospace

Rockets

Deep Blue Aerospace (深蓝航天) is a Chinese commercial launch startup built around vertically landing, reusable kerosene–liquid oxygen rockets - positioning itself as one of China's closest analogs to early SpaceX. Founded in 2016 and headquartered in Nantong, it has flown a series of VTVL hop tests, most notably a September 2024 high-altitude flight that completed 10 of 11 objectives with ~0.5 m landing accuracy before an anomaly during the final engine shutdown damaged the stage on touchdown. The company is now preparing the maiden flight of its medium-lift Nebula-1, which can loft up to 2,000 kg to LEO on nine Thunder-R engines and is designed for first-stage recovery; the first Nebula-1A vehicle was rolled out in March 2026 to a new sea-recovery pad on Lianli Island at Haiyang - which reached full launch-capable status after an integrated test mission on March 30–31, 2026 - for a debut orbital flight that will attempt a first-stage splashdown recovery. The originally targeted mid-2026 debut has slipped, with launch trackers now listing the flight no earlier than December 2026. Deep Blue is also developing the much larger Nebula-2 (25,000+ kg to LEO) and has begun pre-selling suborbital space-tourism tickets for flights targeted in 2027.
