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.

Tesla will resolve its massive recall of nearly three million vehicles in China with stickers and a software update.
On Friday, Chinese regulators filed recall plans against Tesla, Xiaomi, Leapmotor, Xpeng, Chery, Geely, Dongfeng, Arcfox, and FAW to resolve what is essentially a carbon-copy issue throughout each of the companies’ vehicle models: emergency door release latches are simply not visible enough.
Tesla door handle saga gets its latest chapter and a big change is coming
The companies will be required to add things that will make these latches, which will open the door in the event of an emergency, more visible. Of the 7 million vehicles impacted, Tesla accounts for 2,975,910 units. More than 1.9 million of those are Model Y vehicles, with the rest, just over 970,000, being Model 3s.
To resolve the issue, Tesla is going to add warning labels to the emergency latches free of charge, and then utilize an Over-the-Air update to add a post-crash window-lowering strategy, according to CNEVpost.
This massive effort to fix the all-electric Model Y and Model 3’s emergency latch system comes just months after several probes across various markets identified the trouble some had identifying this latch. Those who had gotten involved in car accidents that stripped the vehicle of its power were not aware that every Tesla has emergency door latches.
China’s State Administration for Market Regulation (SAMR) said that severe crashes that disable a vehicle’s low-voltage system could not only hinder occupants from getting out, but also make it more difficult for emergency response workers to gain entry.
SAMR is starting to tighten the regulations it has on door handles on vehicles. A new mandatory national standard will take effect for all models starting January 1, 2027, and will require all doors to be equipped with mechanical release mechanisms. This will effectively end purely electronic door handles. Models already on sale with type approval have been granted a two-year transition period, which will enable things to change until January 2029.
Tesla has officially confirmed plans to bring its all-electric Semi truck to Europe, with full specifications and market-launch details set for unveiling at the IAA Transportation trade fair in Hannover, Germany.
The event runs September 15–20, with a possible press preview on September 14. The announcement, shared via Tesla’s Semi account, marks a significant expansion beyond North America nearly nine years after the truck’s original 2017 reveal.

In the United States, the Semi’s path has been gradual. Limited pilot production and customer deliveries began in late 2022, primarily to fleets such as PepsiCo. After years of refinement, high-volume manufacturing started on April 29, 2026, at a dedicated facility adjacent to Gigafactory Nevada.
The plant targets an annual capacity of 50,000 units, though the ramp is expected to be gradual, with “many thousands” of trucks projected by the end of 2026.
Demand is building, with recent orders including 500 units for Einride (deliveries starting September 2026, serving Amazon and others) and hundreds more from operators such as WattEV. Pricing stands at approximately $260,000 for the Standard Range and $290,000 for the Long Range before incentives.
Tesla Semi pricing revealed after company uncovers trim levels
Earlier in 2026, Tesla finalized production specifications that incorporated substantial updates. In February, the company detailed two variants designed for a full 82,000-pound gross combination weight.
The Standard Range offers about 325 miles of range with a 548 kWh battery and curb weight under 20,000 pounds. The Long Range delivers roughly 500 miles with an 822 kWh pack and a 23,000-pound curb weight. Both use three independent rear-axle motors producing up to 800 kW (about 1,073 horsepower), achieve energy consumption of around 1.7 kWh per mile, and support megawatt-class charging at up to 1.2 MW—recovering about 60 percent of range in 30 minutes through the MCS standard.
Additional refinements include a roughly 1,000-pound weight reduction versus earlier prototypes, improved aerodynamics, a 48-volt electrical architecture, electric power take-off up to 25 kW for refrigerated trailers, and fleet management software with over-the-air updates.
These advances position the Semi as a competitive option against diesel trucks on operating costs and performance. For Europe, adaptations such as lighting, cab configurations (including potential sleeper options), and regulatory compliance are anticipated.
With series production underway in Nevada and major fleet commitments secured, the upcoming IAA reveal will clarify timelines, European-specific specs, and pricing, potentially accelerating electrification of heavy-duty freight on both continents.

Tesla Robotaxi gets a massive upgrade in Nevada
Nevada regulators just approved a massive expansion of Tesla’s robotaxi fleet across the entire county.
Tesla’s robotaxi footprint in Nevada just grew by roughly 500 times in a single regulatory vote.
The Nevada Transportation Authority approved Tesla’s full Autonomous Vehicle Network Company permit on Thursday, clearing the way for the company to deploy up to 5,000 driverless vehicles across Clark County over the next 12 months. The decision came during a four hour general session meeting that Tesla investor Sawyer Merritt watched live and reported on X, noting the vote replaces the interim order that had limited Tesla to just 10 robotaxis on a narrow stretch of the Las Vegas Strip.

That earlier cap, covered here after it surfaced on August 13, came with restrictions that looked stricter than what Tesla runs in Austin: a 45 mph speed ceiling, no airport pickups, and a geofence confined to the Strip corridor. The new approval extends Tesla’s operating authority to all of Clark County, with room to request an even wider geofence across the state.
Tesla representatives at the meeting said they have no intention of putting 5,000 cars on the road right away. Commercial rides are expected to start within 30 days, pending vehicle inspections, insurance filings, and fare approval, the standard steps every robotaxi operator in Nevada has had to clear.
Tesla’s own Robotaxi account replied to the news with a short line, The golden future is upon us.
The timing lines up with Tesla’s broader robotaxi push this month. The company is preparing to open Cybercab rides to the public in Austin as soon as this month, and it opened a sweepstakes for riders to win a seat at the launch event. Tesla filed its original application for a 5,000 vehicle Nevada fleet back in June, a request regulators trimmed to 10 vehicles when they issued the interim order in July. Thursday’s vote effectively grants the number Tesla asked for from the start.
Zoox, the Amazon owned robotaxi operator, has run in Nevada since 2025 and was capped at 100 vehicles before Thursday’s decision. Tesla’s new ceiling puts it well ahead of that comparison on paper, though the company has said its actual fleet size will depend on how quickly FSD v15 rolls out, the software update executives have called the gateway to scaling unsupervised robotaxi operations nationwide.
