SpaceX ships 200th Falcon second stage, highlighting the flip-side of booster reuse

Published

on

SpaceX has built and shipped its 200th Falcon second stage, highlighting the often underappreciated rocket’s record of achievement on the ground and in flight.

Approximately 13 years ago, in late 2009 or early 2010, SpaceX shipped the first flightworthy prototype of the first iteration of its Falcon 9 second stage. In June 2010, Falcon 9 lifted off on its inaugural test flight and, with the help of that second stage, successfully launched a boilerplate mockup of Dragon spacecraft into orbit. Since Falcon 9’s surprising inaugural success, SpaceX’s Falcon 9 and Falcon Heavy rockets have launched another 187 times for a total of 188 launches and 189 assembled rockets. Every one of those launches has required a new second stage, and all but one (Crew Dragon’s In-Flight Abort test) required a new Merlin Vacuum engine.

While SpaceX is most famous for the successful realization of rapidly reusable Falcon boosters, the company’s overall success is also inextricably linked to Falcon second stages, which are and always will be expended after every launch. For every spectacular Falcon booster landing or reuse record, a Falcon second stage either unceremoniously burns up in Earth’s atmosphere or finds itself stranded in orbit. As a result, even as SpaceX’s reusability has allowed it to launch more than ever before with a fleet of just 10-20 Falcon boosters, the company has had to expand the production of Falcon second stages extraordinary levels.

SpaceX just completed its 188th Falcon 9/Heavy launch, so the 200th flightworthy second stage and Merlin Vacuum (MVac) engine are probably scheduled to launch sometime in January 2023. In the last 365 days, SpaceX’s Falcon rockets have completed 59 successful orbital launches. Every launch has required a new second stage, so SpaceX, on average, has consistently built, shipped, and tested a new Falcon second stage every 6.2 days for more than a year.

Thanks to SpaceX’s record-breaking 2022 launch cadence, which has resulted in Falcon 9 launching more in one calendar year than any other rocket in history, the Falcon second stage has likely become the most-produced orbital rocket stage in decades. Barring surprises, SpaceX is on track to achieve CEO Elon Musk’s goal of 60 Falcon launches in 2022. But SpaceX isn’t done yet, and CEO Elon Musk says that the company is targeting “up to 100 launches” in 2023. After nearly doubling between early and late 2021, that will require Falcon second stage production to increase another ~67% year-over-year.

In its 12.5-year career, Falcon 9 has suffered three failures. In October 2012, on its third launch, one of Falcon 9’s nine Merlin 1C booster engines failed in flight. The main mission – a Dragon cargo mission to the International Space Station – was saved by the second stage, which autonomously compensated for the lost performance, but a secondary payload (Orbcomm’s first OG2 satellite prototype) was lost as a result. In June 2015, a faulty strut inside Falcon 9’s second stage caused a helium pressure vessel to break loose and rupture, destroying the rocket mid-flight. And in September 2016, during a prelaunch static fire test, a similar pressure vessel inside an upgraded Falcon 9’s second stage spontaneously sparked, causing an explosion that destroyed the rocket while it was still on the ground.

As a result, while problems with Falcon second stages have technically caused both of Falcon 9’s only catastrophic failures, it’s still true that a free-flying Falcon second stage has never failed in flight. The same is true for the second stage’s Merlin Vacuum engine: over hundreds of burns and more than 70,000 seconds of operation, MVac has never failed in flight.

SpaceX announced the completion of its 100th MVac engine in April 2020, which means that it took ~130 months to build the first 100 and ~30 months to build the next 100. (SpaceX)

After Falcon 9’s successful November 3rd, 2022 launch of the Eutelsat Hotbird 13G communications satellite, SpaceX’s Falcon rocket family has completed 160 launches without failure, arguably making it the most reliable rocket family in history. To achieve that feat with its partially-reusable Falcon 9 and Falcon Heavy rockets, SpaceX has had to master reusable and expendable orbital rockets to a degree that only a few other companies or space agencies in history can claim to have matched or exceeded, and that none have achieved simultaneously.

Elon Musk

Elon Musk’s net worth is nearing $800 billion, and it’s no small part due to xAI

A newly confirmed $20 billion xAI funding round valued the business at $250 billion, adding an estimated $62 billion to Musk’s fortune.

Elon Musk moved within reach of an unprecedented $800 billion net worth after private investors sharply increased the valuation of xAI Holdings, his artificial intelligence and social media company. 

A newly confirmed $20 billion funding round valued the business at $250 billion, adding an estimated $62 billion to Musk’s fortune and widening his lead as the world’s wealthiest individual.

xAI’s valuation jump

Forbes confirmed that xAI Holdings was valued at $250 billion following its $20 billion funding round. That’s more than double the $113 billion valuation Musk cited when he merged his AI startup xAI with social media platform X last year. Musk owned roughly 49% of the combined company, which Forbes estimated was worth about $122 billion after the deal closed.

xAI’s recent valuation increase pushed Musk’s total net worth to approximately $780 billion, as per Forbes’ Real-Time Billionaires List. The jump represented one of the single largest wealth gains ever recorded in a private funding round.

Interestingly enough, xAI’s funding round also boosted the AI startup’s other billionaire investors. Saudi investor Prince Alwaleed Bin Talal Alsaud held an estimated 1.6% stake in xAI worth about $4 billion, so the recent funding round boosted his net worth to $19.4 billion. Twitter co-founder Jack Dorsey and Oracle co-founder Larry Ellison each owned roughly 0.8% stakes that are now valued at about $2.1 billion, increasing their net worths to $6 billion and $241 billion, respectively.

The backbone of Musk’s net worth

Despite xAI’s rapid rise, Musk’s net worth is still primarily anchored by SpaceX and Tesla. SpaceX represents Musk’s single most valuable asset, with his 42% stake in the private space company estimated at roughly $336 billion. 

Tesla ranks second among Musk’s holdings, as he owns about 12% of the EV maker’s common stock, which is worth approximately $307 billion.

Over the past year, Musk crossed a series of historic milestones, becoming the first person ever worth $500 billion, $600 billion, and $700 billion. He also widened his lead over the world’s second-richest individual, Larry Page, by more than $500 billion.

Tesla Cybercab sighting confirms one highly requested feature

The feature will likely allow the Cybercab to continue operating even in conditions when its cameras could be covered with dust, mud, or road grime.

A recent sighting of Tesla’s Cybercab prototype in Chicago appears to confirm a long-requested feature for the autonomous two-seater. 

The feature will likely allow the Cybercab to continue operating even in conditions when its cameras could be covered with dust, mud, or road grime.

The Cybercab’s camera washer

The Cybercab prototype in question was sighted in Chicago, and its image was shared widely on social media. While the autonomous two-seater itself was visibly dirty, its rear camera area stood out as noticeably cleaner than the rest of the car. Traces of water were also visible on the trunk. This suggested that the Cybercab is equipped with a rear camera washer.

As noted by Model Y owner and industry watcher Sawyer Merritt, a rear camera washer is a feature many Tesla owners have requested for years, particularly in snowy or wet regions where camera obstruction can affect visibility and the performance of systems like Full Self-Driving (FSD).

While only the rear camera washer was clearly visible, the sighting raises the possibility that Tesla may equip the Cybercab’s other external cameras with similar cleaning systems. Given the vehicle’s fully autonomous design, redundant visibility safeguards would be a logical inclusion.

The Cybercab in Tesla’s autonomous world

The Cybercab is Tesla’s first purpose-built autonomous ride-hailing vehicle, and it is expected to enter production later this year. The vehicle was unveiled in October 2024 at the “We, Robot” event in Los Angeles, and it is expected to be a major growth driver for Tesla as it continues its transition toward an AI- and robotics-focused company. The Cybercab will not include a steering wheel or pedals and is intended to carry one or two passengers per trip, a decision Tesla says reflects real-world ride-hailing usage data.

The Cybercab is also expected to feature in-vehicle entertainment through its center touchscreen, wireless charging, and other rider-focused amenities. Musk has also hinted that the vehicle includes far more innovation than is immediately apparent, stating on X that “there is so much to this car that is not obvious on the surface.”

Tesla seen as early winner as Canada reopens door to China-made EVs

Tesla had already prepared for Chinese exports to Canada in 2023 by equipping its Shanghai Gigafactory to produce a Canada-specific version of the Model Y.

Tesla seems poised to be an early beneficiary of Canada’s decision to reopen imports of Chinese-made electric vehicles, following the removal of a 100% tariff that halted shipments last year.

Thanks to Giga Shanghai’s capability to produce Canadian-spec vehicles, it might only be a matter of time before Tesla is able to export vehicles to Canada from China once more. 

Under the new U.S.–Canada trade agreement, Canada will allow up to 49,000 vehicles per year to be imported from China at a 6.1% tariff, with the quota potentially rising to 70,000 units within five years, according to Prime Minister Mark Carney. 

Half of the initial quota is reserved for vehicles priced under CAD 35,000, a threshold above current Tesla models, though the electric vehicle maker could still benefit from the rule change, as noted in a Reuters report.

Tesla had already prepared for Chinese exports to Canada in 2023 by equipping its Shanghai Gigafactory to produce a Canada-specific version of the Model Y. That year, Tesla began shipping vehicles from Shanghai to Canada, contributing to a sharp 460% year-over-year increase in China-built vehicle imports through Vancouver. 

When Ottawa imposed a 100% tariff in 2024, however, Tesla halted those shipments and shifted Canadian supply to its U.S. and Berlin factories. With tariffs now reduced, Tesla could quickly resume China-to-Canada exports.

Beyond manufacturing flexibility, Tesla could also benefit from its established retail presence in Canada. The automaker operates 39 stores across Canada, while Chinese brands like BYD and Nio have yet to enter the Canadian market directly. Tesla’s relatively small lineup, which is comprised of four core models plus the Cybertruck, allows it to move faster on marketing and logistics than competitors with broader portfolios.
