DeepSpace: Chinese rocket startups make tangible progress on the path to orbital launch
In the last six or so months, a range of small Chinese rocket startups have begun to make serious progress in the nascent commercial industry, including several inaugural orbital launch attempts, extensive propulsion testing, and more. Rising above the fray are a handful of uniquely notable companies: Landspace, Linkspace, OneSpace, and iSpace (creative, I know).
While the names leave something lacking, several companies have truly impressive ambitions and can already point to major tech development programs as evidence for their follow-through. Linkspace is arguably the most interesting company with respect to what they are doing today, while Landspace has the ambition and expertise to build and launch some truly capable rockets in the near-term.
OneSpace & iSpace
- OneSpace recently made its first attempt at orbital launch after completing an OS-M1 rocket, nominally capable of placing 200 kg (450 lb) in a 300 km (190 mi) low Earth orbit (LEO). The March 2019 attempt failed 45 seconds into launch, likely caused by an improperly-installed gyroscope that guided the rocket in the wrong direction.
- This failure is by no means a bad thing. Reaching orbit on one’s first try is extraordinarily rare, particularly for private companies with no prior experience developing launch vehicles. SpaceX’s first three Falcon 1 launches failed before success was found on Flight 4. Rocket Lab’s Electron launch debut was forced to abort before reaching orbit due to faulty third-party communications equipment.
- OneSpace has several additional suborbital OS-X launches and may be able to attempt one additional OS-M1 orbital launch before the end of 2019.
- Down the road, the company wants to enhance its payload capabilities by adding additional solid rocket strap-on boosters to OS-M1 (designated M2 and M4). OS-M4 would be able to launch as much as 750 kg (1650 lb) into LEO.
- iSpace is in a similar boat. Its Hyperbola-1 rocket relies on three solid stages and a liquid fourth stage and is designed to place 300 kg (660 lb) into LEO. iSpace has plans to attempt the company’s first orbital launch as early as June 2019.
- Having already raised more than $100M in investment, iSpace also has strong backing for the development of its next-gen Hyperbola-2 rocket. The methalox-based vehicle will have a reusable booster capable of vertical landings and should be able to launch almost 2 tons to LEO. The rocket’s first launch is expected to occur no earlier than late 2020.
Linkspace
- In April 2019, Linkspace began flight-testing a sort of miniature version of SpaceX’s Falcon 9 Grasshopper testbed. Known as NewLine Baby, the small suborbital prototype is designed to improve the company’s technical familiarity with vertically landing orbital-class rocket boosters after missions. Thus far, hop testing has been a great success.
- Baby weighs 1.5 t (1100 lb), is 8.1m (27 ft) tall, and is powered by five liquid methane and oxygen (methalox) rocket engines.
- The company hopes to transfer the knowledge gained into NewLine-1, a partially reusable orbital-class rocket designed to place 200 kg in LEO. Linkspace could attempt their first orbital launch as early as 2021.
- The two-stage rocket’s booster would separate a few minutes into launch and attempt a vertical landing on a pad or boat, the same approach SpaceX has used with unprecedented success.
- The similarities with SpaceX’s Falcon 9 are honestly not the worst thing. SpaceX has no patent on vertically landing rockets and has never attempted to corner the industry. Copying a successful new paradigm is certainly better than doing nothing.
- (For the record, Blue Origin did the exact opposite and attempted to patent vertically landing rockets at sea in 2014, before the company had conducted a single serious launch and at the same time as SpaceX was already planning barge recoveries of Falcon 9 boosters.)
- One could even say that Linkspace and several other Chinese companies are actually doing better than industry heavyweights like ULA and Arianespace by simply embracing the new paradigm, as opposed to denial, pearl-clutching, and half-measure responses.
Landspace
- Finally, there is Landspace. Perhaps the most exciting company of the bunch, Landspace is developing a fairly large methalox launch vehicle named ZhuQue-2 (ZQ-2). Powered by several fairly large TQ-12 liquid rocket engines, ZQ-2 is designed to launch up to 4t (8800 lb) to an orbit of 200 km (120 mi) and would produce up to 2650 kN (600,000 lbf) of thrust at liftoff, about a third of SpaceX’s Falcon 9.
- The two-stage ZQ-2 is not currently being designed for reusability, but an upgraded three-stage variant (ZQ-2A) would feature a much larger payload fairing and improve payload performance to 200 km by 50%, from 4t to 6t.
- Landspace will attempt ZQ-2’s inaugural launch as early as 2020. Critically, the company is just completed the first full-scale prototype of the TQ-12 engine meant to power the rocket and could begin static fire tests just a month or two from now.
- Tianque-12 (TQ-12) is a fairly unique engine. Powered by liquid methane and oxygen (methalox), TQ-12 uses a gas-generator propulsion cycle and is designed to produce up to 80t (175,000 lbf) of thrust. In a sense, TQ-12 is basically a slightly less powerful methalox variant of SpaceX’s Merlin 1D engine.
- The fact that Landspace is already in a position to begin static fire tests of the engine powering its next-gen rocket bodes very well for the company’s future plans. At a minimum, it likely means that Landspace is much closer to offering multi-ton commercial launch services compared to its competitors.
- Aside from its next-gen ambitions, Landspace has also developed a much smaller three-stage rocket known as ZQ-1. Capable of launching up to 300 kg into LEO, ZQ-1 nearly reached orbit on its October 2018 launch debut, failing midway through its third-stage burn.
- For now, the Chinese launch startup scene is downright frenetic. The title of “first private Chinese company to reach orbit” has yet to be awarded, and more than half a dozen groups are practically racing to secure it.
Mission Updates:
- SpaceX’s CRS-17 Cargo Dragon spacecraft successfully rendezvoused and berthed with the ISS on May 6th.
- Potentially less than two weeks after the Falcon 9’s May 4th CRS-17 launch, SpaceX’s first dedicated Starlink mission is scheduled to occur as early as May 13th, although delays of a few days are likely.
- SpaceX’s second West Coast launch of 2019 – carrying Canada’s Radarsat Constellation – finally has an official launch date – June 11th. The mission will reuse Falcon 9 B1051.
- Falcon Heavy’s third launch remains tentatively scheduled no earlier than June 22nd.

Tesla begins ‘honorable discharge’ of Model S, X with massive move
In a significant development that marks the beginning of the end for two of its longest-running models, Tesla has removed the custom order configurator for the Model S sedan and Model X SUV from its website.
Tesla has officially started the “honorable discharge” of the Model S and Model X with a massive move, removing the two vehicles from Custom Orders and only offering inventory options.
It is the latest move Tesla has made to pull the Model S and Model X from its lineup, a decision CEO Elon Musk announced during its last quarterly earnings call.
Tesla brings closure to flagship ‘sentimental’ models, Musk confirms
In a significant development that marks the beginning of the end for two of its longest-running models, Tesla has removed the custom order configurator for the Model S sedan and Model X SUV from its website.
As of April 1, visitors to tesla.com/model-s and tesla.com/modelx are now redirected exclusively to limited inventory listings rather than a design studio, allowing buyers to select paint, wheels, interior options, or performance upgrades. Only pre-built vehicles currently in stock are available for purchase or lease.
Tesla CEO Elon Musk confirmed the change directly on X, posting: “Custom orders of the Tesla Model S & X have come to an end. All that’s left are some in inventory.”

We will have an official ceremony to mark the end of an era.” Accompanying the statement was a throwback photo from the Model S production launch in 2012, underscoring the emotional weight of the decision.
Musk had first signaled the phase-out during the company’s Q4 2025 earnings call in January, describing it as time for an “honorable discharge” of the programs to free up resources at the Fremont factory for Optimus humanoid robot production and autonomous vehicle initiatives.
The Model S, introduced in 2012, and the Model X, which followed in 2015, were instrumental in establishing Tesla as a premium electric vehicle leader.
The sedan offered class-leading range and acceleration, while the SUV’s signature falcon-wing doors became an iconic feature. Together, they proved EVs could compete in the luxury segment. Yet sales volumes have dwindled in recent years as Tesla prioritized higher-volume Model 3 and Model Y vehicles.
The flagships now represent a tiny fraction of overall deliveries, making continued custom production inefficient as the company accelerates toward robotaxis and next-generation platforms.
Prospective buyers are urged to act quickly. Remaining U.S. inventory vehicles—some nearly new—may include incentives such as lifetime free Supercharging, Full Self-Driving (Supervised) capability, and premium connectivity, depending on configuration.
Leasing options start around $1,699 per month for select Model X units, though exact pricing and availability fluctuate. International markets, including Europe and China, have already seen similar restrictions in recent months.
The move aligns with Tesla’s broader strategy to streamline its lineup and redirect manufacturing capacity toward autonomy and AI-driven products. While some enthusiasts lament the loss of personalization, the company views the transition as necessary progress.
Tesla has indicated that once the current inventory sells out, new Model S and Model X vehicles will no longer be offered.
For loyal owners and fans, the promised “official ceremony” may provide a fitting send-off. In the meantime, the website change serves as a clear signal: the era of bespoke flagship Teslas has quietly concluded, and the focus has fully shifted to the future.

SpaceX files confidentially for IPO that will rewrite the record books
SpaceX files confidentially for a record-breaking IPO targeting a $1.75T valuation and $80B raise, driven by Starlink growth and its xAI merger.
Elon Musk’s rocket and satellite company submitted its draft registration to the U.S. Securities and Exchange Commission today for an initial public offering, targeting June at a $1.75 trillion valuation. This would be the largest in history.
SpaceX has filed confidentially with the SEC, first reported by Bloomberg. SpaceX would be valued above every S&P 500 company except Nvidia, Apple, Alphabet, Microsoft, and Amazon.
The filing uses a confidential process that allows companies to work through SEC disclosures privately before initiating a public roadshow. With a June target, official details through a formal prospectus is expected to go public in April or early May, after which SpaceX must wait at least 15 days before beginning investor marketing.
While SpaceX is best known for its Falcon 9 and Starship rockets, the $1.75 trillion valuation is anchored by Starlink, its satellite internet service. Starlink ended 2025 with 9.2 million subscribers and over $10 billion in revenue, which is a figure analysts project could reach a staggering $24 billion by the end of 2026. A February all-stock merger with xAI, Musk’s artificial intelligence venture, further boosted the valuation.

Bank of America, Goldman Sachs, JPMorgan Chase, and Morgan Stanley are lined up as senior underwriters. SpaceX is also considering a dual-class share structure to preserve insider voting control, and plans to allocate up to 30% of shares to retail investors, which is roughly three times the typical norm.

Elon Musk hints at “official ceremony” with throwback photo to close Tesla Model S, Model X chapter
Elon Musk promises an official ceremony to mark the end of Tesla Model S and Model X production.
Tesla has officially begun winding down production of the Model S and Model X, sending farewell emails to U.S. customers on March 27 and updating the website to reflect the end of the line. Shoppers visiting Tesla.com now find only a limited set of Model S and Model X inventory units available for purchase, with no option to configure a new factory build. The move formalizes what CEO Elon Musk announced on the company’s Q4 2025 earnings call in January, when he said it was “time to basically bring the Model S and X programs to an end with an honorable discharge.”
Musk posted on X a throwback photo of himself speaking at the Model S production launch in 2012, and noting “We will have an official ceremony to mark the ending of an era. I love those cars.”
The mention of an official ceremony is notable. Tesla has not held a formal farewell event for a vehicle before, and Musk’s wording suggests this will be something deliberate rather than a quiet line shutdown. Given that Musk’s X post shows a photo of him on stage with a microphone in front of an audience at the Fremont factory, it wouldn’t be too far-fetched to expect a closing ceremony to take place at the same location. Perhaps? Whether it becomes a public event, a private gathering for employees, or a livestreamed moment on X remains to be seen.

The Model S first went on sale nearly fifteen years ago and was Tesla’s first fully in-house designed vehicle, proving that an electric car could be fast, desirable, and capable of long distance on a single charge. The Model X followed in 2015, turning heads with its unmistakable and distinctive falcon-wing doors, while becoming one of the first all-electric SUVs on the market. Tesla’s two flagship vehicles would ultimately push legacy automakers to take all-electric transportation seriously and help fund development of the more affordable Model 3 and Model Y.
By 2025, however, both models had been reduced to a rounding error in Tesla’s sales figures. Musk was direct about what comes next, stating “We are going to convert that production space to an Optimus factory. It’s part of our overall shift to an autonomous future.”

That shift is already underway. Tesla officially started Optimus Gen 3 production at its Fremont factory in January 2026, with the line targeting a run rate of one million units per year. The Gen 3 robot features 22 degrees of freedom per hand, runs on Tesla’s AI5 chip, and shares the same neural network architecture as Full Self-Driving. A dedicated Optimus factory at Gigafactory Texas is also under construction, with a planned annual capacity of 10 million units. The production lines that once built the Model S and Model X are being converted to support that ramp.
Tesla confirmed it will continue to support existing owners with service, software updates, and parts for as long as people own the vehicles. For buyers still interested in a new example, remaining U.S. inventory is discounted and the window is closing fast.
