DeepSpace: China tests SpaceX-reminiscent grid fins after iSpace snags orbital milestone
Eric Ralph · August 1st, 2019
Welcome to the latest edition of DeepSpace! Each week, Teslarati space reporter Eric Ralph hand-crafts this newsletter to give you a breakdown of what’s happening in the space industry and what you need to know.
Although the accomplishments aren’t quite as flashy as a launch to the Moon, the last week has featured a number of interesting developments and significant milestones from both the state-run and quasi-commercial wings of Chinese spaceflight.
In the commercial realm, Chinese startup iSpace became the country’s first commercial entity to successfully reach orbit, achieving the feat with a three-stage solid rocket called Hyperbola 1.
One day later, state-owned Chinese company China Aerospace Science and Technology Corporation (CASC) completed its 50th successful Long March 2 rocket launch on a relatively routine government spy satellite mission. Unique was the fact that the rocket marked the first flight test of grid fins – extremely similar to those used on SpaceX’s Falcon 9 – on a Long March rocket.
The march to orbit
- In 2019 alone, three Chinese spaceflight startups have made their first orbital launch attempts and more tries are planned in the second half of the year. OneSpace and LandSpace both got close but ended up suffering partial failures that cut their attempts short before safely reaching orbit.
- Enter iSpace: one of dozens of startups in a burgeoning Chinese commercial spaceflight industry, the company’s three-stage solid rocket – named Hyperbola 1 – became the first Chinese startup-launched rocket to successfully reach orbit on July 25th.
- Although a large amount of the hardware may well have been procured (or licensed) wholesale from CASC, the success still signifies the start of a new alternative to government launches for companies (and perhaps government agencies) seeking to launch smaller satellites.
- Hyperbola 1 stands about 21m (68 ft) tall, is 1.4m (4.6 ft) in diameter at its widest point, and weighs about 31 tons (68,000 lb) when fully fueled. Three solid rocket stages are followed by an extremely small fourth stage meant to circularize the payload(s) in low Earth orbit (LEO).
- The rocket is capable of launching as much as 260 kg (570 lb) to a 500 km (310 mi) sun-synchronous orbit (SSO).
- For iSpace, Hyperbola 1 is more of a stopgap measure as the company works to develop Hyperbola 2, a significantly larger launch vehicle meant to feature a reusable booster and internally-developed liquid rocket engines.
- Ultimately, Hyperbola 1 reaching orbit is an exciting milestone, but it will be far more significant when a Chinese startup reaches orbit with a launch vehicle it has truly designed and built itself. A number of companies aim to do just that next year (2020).
The sincerest form of flattery…
- A day later (July 26th) and approximately 1000 miles (1600 km) to the southeast, state-run corporation CASC was preparing for a routine launch of its Long March 2C rocket, carrying a trio of relatively small spacecraft for a government spy satellite constellation.
- Technically known as YW-30 Group-5, the launch was a routine success that just so happened to be the Long March 2 family’s 50th successful launch in more than 35 years. The family has only suffered one in-flight failure.
- Long March 2C is a two-stage rocket that stands 42m (138 ft) tall (shorter than Falcon 9’s first stage), 3.35m (11 ft) wide, and weighs ~233 tons (514,000 lb) fully fueled. The 2C variant is capable of launching ~3850 kg (8500 lb) into LEO and more than 1250 kg (2750 lb) into geostationary transfer orbit (GTO).
- Although the rocket’s 50th launch success milestone is worth recognizing, this particular launch wound up drawing a significantly greater amount of attention for an entirely different reason: attached to the outside of the Long March 2C’s booster interstage was a quartet of immediately familiar grid fins.
- SpaceX has grown famous in the last five or so years for its spectacularly successful Falcon 9 recovery and reusability, aided in no small part by grid fins used by the booster to retain aerodynamic control authority during its hypersonic jaunts through the atmosphere.
- The appearance of grid fins on a Chinese rocket – looking undeniably similar to SpaceX’s first-generation aluminum fins – raised some (moderately xenophobic) ire in the space community, with people falling back on the stereotype of the perceived willingness of Chinese people to flagrantly ‘copy’ ideas.
- Both the stereotype and the grid fin-stoked ire are arguably undeserved. SpaceX did not invent grid fins, nor did it invent the concept of using grid fins to guide suborbital projectiles.
- In fact, CEO Elon Musk would almost certainly be happy to see someone – anyone! – blatantly copy SpaceX’s approach to reusability. A blatant copy, while not exactly worthy of pride, is still a major improvement over companies sticking their heads in the sand and tacitly choosing insolvency and commercial irrelevance rather than admit that they were wrong and SpaceX was right.
-
- (Pauline Acalin – Teslarati)
- According to CASC, this mission’s grid fins were included to flight-test their ability to more carefully guide the booster’s return to Earth. China infamously takes a… lax… approach to range safety, allowing spent boosters and fairings to haphazardly crash into inhabited areas, often containing remnants of their sometimes toxic propellant.
- Indeed, this particular booster did appear to crash in an uninhabited valley, be it thanks to those experimental grid fins or pure chance
- However, aside from not crashing large objects in populated areas, CASC and China have plans to develop a Long March 6 rocket with a reusable booster that will use the same recovery methods as Falcon 9. That rocket could fly as early as 2021 and July 26th’s grid fin test is an obvious sign that work is ongoing.
- If China manages to develop and launch a partially reusable rocket by 2021, they will be miles (and years) ahead of its space agency peers (NASA, ESA, CNES) and companies like ULA and Arianespace.
Thanks for being a Teslarati Reader! Stay tuned for next week’s issue of DeepSpace.

Tesla officially publishes Q4 2025 vehicle delivery consensus
By releasing these numbers directly, Tesla establishes a clear, transparent benchmark ahead of its actual results.
Tesla has taken the rather unusual step of officially publishing its company-compiled Q4 2025 delivery consensus on the Investor Relations site. As per analyst estimates, Tesla is expected to deliver 422,850 vehicles and deploy 13.4 GWh of battery storage systems this Q4 2025.
By releasing these numbers directly, Tesla establishes a clear, transparent benchmark ahead of its actual results, making it harder for narratives to claim a “miss” based on outlier estimates.
Official consensus sets the record straight
Tesla’s IR press release detailed the consensus from 20 analysts for vehicle deliveries and 16 analysts for energy deployments. As per the release, full-year 2025 consensus delivery estimates come in at 1,640,752 vehicles, an 8.3% decline from 2025’s FY deliveries of 1,789,226 cars.
Tesla noted that while it “does not endorse any information, recommendations or conclusions made by the analysts,” its press release does provide a notable reference point. Analysts contributing to the company compiled consensus include Daiwa, DB, Wedbush, Oppenheimer, Canaccord, Baird, Wolfe, Exane, Goldman Sachs, RBC, Evercore ISI, Barclays, Wells Fargo, Morgan Stanley, UBS, Jefferies, Needham, HSBC, Cantor Fitzgerald, and William Blair.
Tesla’s busy Q4 2025
Tesla seems to be pushing hard to deliver as many vehicles as possible before the end of 2025, despite the company’s future seemingly being determined not by vehicle deliveries, but FSD and Optimus’ rollout and ramp. Still, reports from countries such as China are optimistic, with posts on social media hinting that Tesla’s delivery centers in the country are appearing packed as the final weeks of 2025 unfold.
The Tesla Model Y and Model 3 are also still performing well in China’s premium EV segment. Based on data from January to November, the Model Y took China’s number one spot in the RMB 200,000-RMB 300,000 segment for electric vehicles, selling 359,463 units. The Model 3 sedan took third place, selling 172,392. This is quite impressive considering that both the Model Y and Model 3 command a premium compared to their domestic rivals.

Tesla’s Elon Musk accepts invitation to Israel’s Smart Transportation Conference
The announcement was shared by the Israeli Prime Minister in a post on social media platform X.
Elon Musk has reportedly accepted an invitation from Israeli Prime Minister Benjamin Netanyahu to participate in the country’s Smart Transportation Conference in March 2026.
The announcement was shared by the Israeli Prime Minister in a post on social media platform X.
A call and an invitation
Netanyahu posted on X about Musk, stating in Hebrew: “Last night, I held a joint conference call from Florida with entrepreneur Elon Musk, Minister of Transportation Miri Regev, and the head of the National AI Headquarters, Erez Askal. In the framework of the conversation, Musk responded to my invitation and Minister Regev’s invitation to participate in the Smart Transportation Conference that will be held in March.”
Netanyahu added that he and Musk discussed continuing initiatives such as the promotion of autonomous vehicle laws and the boosting of AI technologies in Israel. This, according to the Prime Minister, is aimed at making the country a global leader in emerging technologies.
“Additionally, we discussed the continuation of collaborations with Tesla and the promotion of the law pertaining to autonomous vehicles. I spoke at length with Musk about promoting and developing artificial intelligence technologies in Israel, and I said in our conversation: We intend to catapult Israel and turn it into a global leader in the field, just as we did in cyber and other technologies,” Netanyahu added.
Tesla FSD’s upcoming rollout in Israel
Elon Musk’s upcoming conference appearance in Israel could hint at Tesla’s upcoming rollout of FSD and its Robotaxi service in the country. Previous reports have hinted that FSD is nearing regulatory approval in Israel, following strong advocacy from local owners and direct intervention from the government.
Nearly 1,000 Tesla drivers petitioned authorities, highlighting FSD’s potential to enhance road safety. Transport and Road Safety Minister Miri Regev responded positively on X, writing “I’ve received the many referrals from Tesla drivers in Israel! Tesla drivers? Soon you won’t need to hold the steering wheel.”
Minister Regev has instructed the ministry’s Director-General to accelerate the approval process, including necessary tests. A dedicated working group, led by Moshe Ben-Zaken, is also coordinating with regulatory and safety agencies to meet international standards.

Tesla China delivery centers look packed as 2025 comes to a close
Needless to say, it appears that Tesla China seems intent on ending 2025 on a strong note.
Tesla’s delivery centers in China seem to be absolutely packed as the final days of 2025 wind down, with photos on social media showing delivery locations being filled wall-to-wall with vehicles waiting for their new owners.
Needless to say, it appears that Tesla China seems intent on ending 2025 on a strong note.
Full delivery center hints at year-end demand surge
A recent image from a Chinese delivery center posted by industry watcher @Tslachan on X revealed rows upon rows of freshly prepared Model Y and Model 3 units, some of which were adorned with red bows and teddy bears. Some customers also seem to be looking over their vehicles with Tesla delivery staff.
The images hint at a strong year-end push to clear inventory and deliver as many vehicles as possible. Interestingly enough, several Model Y L vehicles could be seen in the photos, hinting at the demand for the extended wheelbase-six seat variant of the best-selling all-electric crossover.
Strong demand in China
Consumer demand for the Model Y and Model 3 in China seems to be quite notable. This could be inferred from the estimated delivery dates for the Model 3 and Model Y, which have been extended to February 2026 for several variants. Apart from this, the Model Y and Model 3 also continue to rank well in China’s premium EV segment.
From January to November alone, the Model Y took China’s number one spot in the RMB 200,000-RMB 300,000 segment for electric vehicles, selling 359,463 units. The Model 3 sedan took third place, selling 172,392. This is quite impressive considering that both the Model Y and Model 3 are still priced at a premium compared to some of their rivals, such as the Xiaomi SU7 and YU7.
With delivery centers in December being quite busy, it does seem like Tesla China will end the year on a strong note once more.
