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.
  • 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 launches Cybertruck orders in a new market with a catch

Tesla is launching Cybertruck orders in a new market, but there’s a bit of a catch.

The Cybertruck was launched in the Middle East earlier this year, as Tesla launched the ability to place a reservation for the all-electric pickup in the United Arab Emirates. It would be the first market outside of North America that would have the ability to place an order for the Cybertruck.

Tesla confirms Cybertruck will make its way out of North America this year

Other markets where the vehicle has been widely requested, like Europe and Asia, have still not approved the vehicle to be sold to the public, mostly because of size and design restrictions.

However, in the UAE, Tesla is opening up the ability for those who placed reservations for the vehicle to finally put in their order. The Order Configurator is only available to those who have already placed a reservation; it is not yet available to the public.

Tesla said it would open up the public online configurator across the Middle East in the coming weeks:

The UAE is not the only country that will have access to the Cybertruck, as fans in other Middle Eastern countries will also be able to place orders soon. Tesla announced back in April that Saudi Arabia and Qatar would also have Cybertruck deliveries.

These vehicles will be built at Tesla’s Gigafactory Texas plant just outside of Austin, as Gigafactory Berlin and Gigafactory Shanghai, two factories located in the same hemisphere as the Middle East, do not have established lines for Cybertruck production.

As for the other markets, Tesla CEO Elon Musk has hinted that the company could develop a smaller Cybertruck for those markets, as he admitted that in the long term, it likely made sense to build a more compact version for regions where roads are traditionally tighter.

There has been no evidence of Tesla developing this more compact version, but it could eventually happen.

Tesla rolls out new life-saving feature for kids in Europe

On average, 37 children die every year from being left in vehicles unattended.

Tesla is rolling out a new life-saving feature in the European market, one that has been available in the United States for some time and can be considered potentially invaluable.

One of the most preventable causes of death for children is being left in cars unattended. On average, 37 children die every year after being left in hot vehicles. The cause of death is usually heatstroke, and it is incredibly avoidable.

Tesla rolls out new crucial safety feature aimed at saving children

However, there are instances where kids are left in vehicles and lose their lives, something that many companies have tried to fight with alerts and features of their own.

Tesla is one of them, as it has rolled out features like ultrasonic sensors to detect heartbeats, interior cameras to detect movement, and alerts to notify parents if they leave someone in the car.

A few months ago, Tesla rolled out a new feature called “Child Left Alone Detection” in the United States. It was described as:

“If an unattended child is detected, the vehicle will flash the exterior indicator lights, play an alert tone, and send a notification to your Tesla app. This will repeat at regular intervals until you return to your vehicle. Cabin data is processed locally and is not transmitted to Tesla.

This feature is enabled by default. To disable, go to Controls > Safety > Child Left Alone Detection.”

This feature was only rolled out in the U.S. at the time. It is now making its way to the European market, according to Not a Tesla App, which detected the rollout in the 2025.32.6 software update.

The rollout of this feature could specifically change many unfortunate situations. For many of us, it seems hard to think about leaving something as precious as another human life in a hot car. Many of us won’t leave our vehicles without our cell phones, so it seems unlikely that someone would do it without a child.

Tesla gets another NHTSA probe, this time related to door handles

“Although Tesla vehicles have manual door releases inside of the cabin, in these situations, a child may not be able to access or operate the releases even if the vehicle’s driver is aware of them.”

Tesla is facing another investigation into its vehicles by the National Highway Traffic Safety Administration (NHTSA), this time related to an issue with its door handles.

In a new Open Investigation named “Electronic door handles become inoperative,” the NHTSA says that it has received nine complaints from owners of the 2021 Tesla Model Y stemming from “an inability to open doors.”

These issues were reported after “parents exited their vehicle after a drive cycle in order to remove a child from the pack seat or placing a child in the back seat before starting a drive cycle.” Parents said they were “unable to reopen a door to regain access to the vehicle.”

Tesla door handles become unlikely hero as they stump road rager

Four of the nine complaints ended with having to break a window to regain access to the cabin.

The NHTSA goes on to explain that, while Teslas do have a manual door release inside the cabin, a child may not be able to access it:

“Although Tesla vehicles have manual door releases inside of the cabin, in these situations, a child may not be able to access or operate the releases even if the vehicle’s driver is aware of them. As a result, in these instances, an occupant who remains inside a vehicle in this condition may be unable to be rapidly retrieved by persons outside of the vehicle.”

It appears that the agency is attributing the issue to a low voltage in the vehicle’s 12V DC battery. This would mean there needs to be some sort of notification to the driver that the battery is running low on power and should be replaced to avoid this issue.

The NHTSA estimates that 174,290 vehicles are potentially impacted by this issue. It plans to assess the scope and severity of the condition, the agency says. The NHTSA also wants to see what approach Tesla uses to supply power to door locks and the reliability of the applicable power supplies.
