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 Supercharger vandalized with frozen cables and anti-Musk imagery amid Sweden union dispute
The incident comes amid Tesla’s ongoing labor dispute with IF Metall.
Tesla’s Supercharger site in Vansbro, Sweden, was vandalized during peak winter travel weeks. Images shared to local media showed frozen charging cables and a banner reading “Go home Elon,” which was complete with a graphic of Musk’s controversial gesture.
The incident comes amid Tesla’s ongoing labor dispute with IF Metall, which has been striking against the company for more than two years over collective bargaining agreements, as noted in a report from Expressen.
Local resident Stefan Jakobsson said he arrived at the Vansbro charging station to find a board criticizing Elon Musk and accusing Tesla of strikebreaking. He also found the charging cables frozen after someone seemingly poured water over them.
“I laughed a little and it was pretty nicely drawn. But it was a bit unnecessary,” Jakobsson said. “They don’t have to do vandalism because they’re angry at Elon Musk.”
The site has seen heavy traffic during Sweden’s winter sports holidays, with travelers heading toward Sälen and other mountain destinations. Jakobsson said long lines formed last weekend, with roughly 50 Teslas and other EVs waiting to charge.
Tesla Superchargers in Sweden are typically open to other electric vehicle brands, making them a reliable option for all EV owners.
Tesla installed a generator at the location after sympathy strikes from other unions disrupted power supply to some stations. The generator itself was reportedly not working on the morning of the incident, though it is unclear whether that was connected to the protest.
The dispute between Tesla and IF Metall centers on the company’s refusal to sign a collective agreement covering Swedish workers. The strike has drawn support from other unions, including Seko, which has taken steps affecting electricity supply to certain Tesla facilities. Tesla Sweden, for its part, has insisted that its workers are already fairly compensated and it does not need a collective agreement,
Jesper Pettersson, press spokesperson for IF Metall, criticized Tesla’s use of generators to keep charging stations running. Still, IF Metall emphasized that it strongly distances itself from the vandalism incident at the Vansbro Supercharger.
“We think it is remarkable that instead of taking the easy route and signing a collective agreement for our members, they are choosing to use every possible means to get around the strike,” Pettersson said.

Tesla Cybertruck owner credits FSD for saving life after freeway medical emergency
The incident was shared by the Tesla owner on social media platform X, where it caught the attention of numerous users, including Tesla CEO Elon Musk.
A Tesla Cybertruck owner has credited Full Self-Driving (FSD) Supervised for saving his life after he experienced a medical emergency on the freeway.
The incident was shared by the Tesla owner on social media platform X, where it caught the attention of numerous users, including Tesla CEO Elon Musk.
In a post on X, Cybertruck owner Rishi Vohra wrote that he had unintentionally fasted for 17 hours, taken medication, and experienced what he described as a severe allergic reaction while driving.
“What started as a normal drive turned terrifying fast. My body shut down. I passed out while driving on the freeway, mid-conversation with my wife on the phone,” he wrote.
Vohra stated that his Tesla was operating with FSD Supervised engaged at the time. According to his account, the Cybertruck detected that he had lost consciousness using its driver monitoring system, slowed down, activated hazard lights, and safely pulled over to the shoulder.
“Thank God my Tesla had Full Self-Driving engaged. It detected I lost consciousness (thanks to the driver monitoring system), immediately slowed, activated hazards, and safely pulled over to the shoulder. No crash. No danger to anyone else on the road,” Vohra wrote.
The Cybertruck owner added that his wife used Life360 to alert emergency services after hearing him go silent during their call. He said responders located him within five minutes. After being attended to, Vohra stated that the vehicle then drove him to the emergency room after he refused to leave his truck on the freeway.
“So the Tesla autonomously drove me the rest of the way to the ER. I walked in, got admitted, and they stabilized me overnight,” he wrote.
He later posted that he was being discharged and thanked Tesla and Elon Musk. Musk replied to the post, writing, “Glad you’re ok!” The official Tesla X account also reposted Vohra’s story with a heart emoji.
Tesla recently published updated safety data of vehicles operating with FSD (Supervised) engaged. As per Tesla’s latest North America figures, vehicles operating with FSD (Supervised) engaged recorded one major collision every 5,300,676 miles. The U.S. average is one major collision every 660,164 miles.
Considering the experience of the Cybertruck owner, Tesla’s safety data does seem to hold a lot of water. A vehicle that is manually driven would have likely crashed or caused a pileup if its driver lost consciousness in the middle of the freeway, after all.

Tesla Cyberbeast price drops to less than $100k but loses Luxe package with FSD
The change adjusts the truck’s positioning in the high-performance premium EV pickup truck segment, where several rivals now command six-figure price tags.
Tesla has reduced the price of the Cyberbeast to below $99,990, but the update also removes a compelling feature set from the vehicle.
The change adjusts the truck’s positioning in the high-performance premium EV pickup truck segment, where several rivals now command six-figure price tags.
Prior to its price adjustment, the Cyberbeast was listed for $114,990. However, the vehicle’s prior configuration included a Luxe package that bundled features such as Full Self-Driving Supervised and other premium inclusions. That package is no longer listed as part of the Cyberbeast.
For its sub $100,000 price, the Cyberbeast offers 325 miles of estimated range, a 0-60 mph time of 2.6 seconds, a payload capacity of 2,271 lbs with the Cyber Wheel, and Powershare.
Interestingly enough, the Cyberbeast now undercuts some of its most powerful competitors with its updated price. The Rivian R1T Quad, for example, starts at $116,900, though the R1T has more range at 374 miles per charge, and it is also a bit faster with a 0-60 mph time of 2.5 seconds.
Other rivals include the GMC Hummer EV 3X Omega Edition Truck, which has a starting MSRP of approximately $148,000 before dealer markups, the Chevy Silverado EV LT Max Range, which starts at over $91,000 before dealer markups, and the GMC Sierra EV Denali Max, which starts at about $101,000.
Considering that rivals like the Rivian R1T Quad, Chevy Silverado EV LT Max Range, and GMC Sierra EV Denali Max outgun the Cyberbeast in raw range, the Cyberbeast’s competitiveness will likely rely on its Full Self Driving Supervised system, which allows it to navigate inner city streets and highways.
For $99 per month, the Cyberbeast practically becomes a self-driving vehicle, and that is something that its rivals cannot match, at least for now.
