DeepSpace: Rocket Lab bucks the saying that ‘space is hard’ with 4th Electron success
This is a free preview of DeepSpace, Teslarati’s new member-only weekly newsletter. Each week, I’ll be taking a deep-dive into the most exciting developments in commercial space, from satellites and rockets to everything in between. Sign up for Teslarati’s newsletters here to receive a preview of our membership program.
Rocket Lab continues to buck the adage that “space is hard” with its small but increasingly reliable Electron rocket. After a slight range hardware malfunction caused a launch abort just shy of orbit during Electron’s inaugural May 2017 launch attempt, Rocket Lab fixed the issue and returned to flight, successfully completing Electron’s first orbital launch in January 2018. On November 11th, 2018, the rocket completed its first truly commercial launch, placing seven various satellite into Low Earth Orbit (LEO), rapidly followed by Electron’s fourth successful launch on December 16th, barely one month later.
On March 29th, Rocket Lab completed yet another milestone launch for Electron, successfully placing its heaviest payload – an experimental ~150 kg DARPA spacecraft known as R3D2 – into an accurate orbit. Even relative to SpaceX’s barebones Falcon 1 launch campaign, which attempted five launches – two successfully – over a three year career, Rocket Lab’s Electron has progressed at an extraordinary pace, taking less than two years to complete its fifth launch and achieving its first launch success after just one attempt and eight months of flight operations.
Relentless progress
- To find a rocket with a comparable record of success less than two years after its first launch attempt, one must jump back more than half a century to the late 1950s and early 1960s, when Russia and the US were putting their industrial mights to the challenge of achieving spacefaring ‘firsts’. Almost all of those original vehicles – including Redstone, Atlas, Delta, Thor, Titan, and even Saturn V – were able to weather early failures and achieve extraordinary launch cadences just 12-24 months after their debuts.
- None, however, were developed as an entirely commercial rocket with almost exclusively private funds, although ESA’s Ariane 3 and 4 vehicles nearly fit the bill, with exemplary commercial track records and impressive acceleration from debut to high launch cadences.
- Incredibly, Rocket Lab has brought Electron from paper to its fourth successful launch in ~16 months on what can only be described as a shoestring budget relative to all past efforts, perhaps even Elon Musk and SpaceX.
- According to public investment records, the small US-based, New Zealand-operated company may have reached orbit for the first time with less than $100M, including ~$70M in equity investment and unspecified development funding from DARPA in the early 2010s.
- Rocket Lab’s Electron rocket is quite small, measuring 1.2 m (~4 ft) wide, 17 m (56 ft) tall, and 12,500 kg (27,600 lb) at liftoff, anywhere from a quarter to half the size of SpaceX’s Falcon 1, by most measures.
- Electron is capable of placing 150–225 kg (330–495 lb) into either a 550 km (340 mi) sun synchronous orbit (SSO) or a lower low Earth orbit (LEO).
- Electron is advertised with a commercial list price of around $6M.
- Aside from Electron’s industry-defying record of achievement, its R3D2 launch is impressive for another reason: the cost of the payload relative to the cost of launch. For a rocket on its fifth-ever launch, DARPA reportedly spent no less than $25M to fund the development of the experimental R3D2 smallsat, while – as mentioned above – the cost of Electron’s launch could have been as low as ~$6M from ink to orbit.
- In slightly different terms, Electron has now launched a payload that could be 4-5X more valuable than itself after just three prior launch successes and less than two years after beginning operations.
- While ~$30M would not be a huge loss for a military agency like DARPA (FY19 budget: $3.4B), DARPA’s trust in Electron demonstrates impressive confidence in not just Electron, but also Rocket Lab’s standards of manufacturing, operations, and mission assurance.
- Relative to a vehicle like Falcon 9 or Atlas V, Electron’s R3D2 mission would be comparable to launching spacecraft worth ~$250M to $500M after just five launches. Both larger rockets accomplished similar feats, but small launch vehicles are historically known for less than stellar reliability.

Go[ing] forth and conquer[ing]
- Put simply, Rocket Lab has managed to build what appears to be a shockingly reliable small launch vehicle with a budget that would make Old Space companies whimper, all while offering a potential cadence of dozens of annual launches at per-launch costs as low as $6M.
- While the cost-per-kg of a $6M Electron launch is still extremely high relative to larger rockets and rideshare opportunities, what Rocket Lab has achieved is nothing short of spectacular in the commercial spaceflight industry.
- If there ever was an actual ‘space race’ to fill the small launch vehicle void created by the growth of small satellite launch demand, Rocket Lab has won that race beyond the shadow of a doubt. There is still plenty of room for competition and additional cost savings from a customer perspective, but Electron is so early to the party that future competition will remain almost entirely irrelevant for the better part of 2-3 more years.
- According to CEO Peter Beck, the company’s ambition is to sustain monthly Electron launches in the nine remaining months of 2019. Flight 6 hardware is likely already on its way to Rocket Lab’s Mahia, New Zealand Launch Complex 1 (LC-1).


Mission Updates
- The second launch of Falcon Heavy – the rocket’s commercial debut – is still scheduled to occur as early as April 7th, but a slip to April 9-10 is now expected. The massive rocket’s static fire – the first for a Block 5 Falcon Heavy – is set to occur as early as Wednesday, April 3rd.
- After Falcon Heavy, Cargo Dragon’s CRS-17 resupply mission is firmly scheduled for April (April 25th), while the first dedicated Starlink launch is now NET May 2019.
- In late May, SpaceX could launch Spacecom’s Amos-17 spacecraft, effectively free to the customer as part of a settlement following the tragic Amos-6 Falcon 9 anomaly that destroy the rocket, satellite, and large swaths of the LC-40 pad in September 2016.

Tesla (TSLA) Q4 and FY 2025 earnings call: The most important points
Executives, including CEO Elon Musk, discussed how the company is positioning itself for growth across vehicles, energy, AI, and robotics despite near-term pressures from tariffs, pricing, and macro conditions.
Tesla’s (NASDAQ:TSLA) Q4 and FY 2025 earnings call highlighted improving margins, record energy performance, expanding autonomy efforts, and a sharp acceleration in AI and robotics investments.
Executives, including CEO Elon Musk, discussed how the company is positioning itself for growth across vehicles, energy, AI, and robotics despite near-term pressures from tariffs, pricing, and macro conditions.
Key takeaways
Tesla reported sequential improvement in automotive gross margins excluding regulatory credits, rising from 15.4% to 17.9%, supported by favorable regional mix effects despite a 16% decline in deliveries. Total gross margin exceeded 20.1%, the highest level in more than two years, even with lower fixed-cost absorption and tariff impacts.
The energy business delivered standout results, with revenue reaching nearly $12.8 billion, up 26.6% year over year. Energy gross profit hit a new quarterly record, driven by strong global demand and high deployments of MegaPack and Powerwall across all regions, as noted in a report from The Motley Fool.
Tesla also stated that paid Full Self-Driving customers have climbed to nearly 1.1 million worldwide, with about 70% having purchased FSD outright. The company has now fully transitioned FSD to a subscription-based sales model, which should create a short-term margin headwind for automotive results.
Free cash flow totaled $1.4 billion for the quarter. Operating expenses rose by $500 million sequentially as well.
Production shifts, robotics, and AI investment
Musk further confirmed that Model S and Model X production is expected to wind down next quarter, and plans are underway to convert Fremont’s S/X line into an Optimus robot factory with a capacity of one million units.
Tesla’s Robotaxi fleet has surpassed 500 vehicles, operating across the Bay Area and Austin, with Musk noting a rapid monthly expansion pace. He also reiterated that CyberCab production is expected to begin in April, following a slow initial S-curve ramp before scaling beyond other vehicle programs.
Looking ahead, Tesla expects its capital expenditures to exceed $20 billion next year, thanks to the company’s operations across its six factories, the expansion of its fleet expansion, and the ramp of its AI compute. Additional investments in AI chips, compute infrastructure, and future in-house semiconductor manufacturing were discussed but are not included in the company’s current CapEx guidance.
More importantly, Tesla ended the year with a larger backlog than in recent years. This is supported by record deliveries in smaller international markets and stronger demand across APAC and EMEA. Energy backlog remains strong globally as well, though Tesla cautioned that margin pressure could emerge from competition, policy uncertainty, and tariffs.

Tesla brings closure to flagship ‘sentimental’ models, Musk confirms
Tesla is bringing closure to its flagship Model S and Model X vehicles, which CEO Elon Musk said several years ago were only produced for “sentimental reasons.”
The Model S and Model X have been light contributors to Tesla’s delivery growth over the past few years, commonly contributing only a few percentage points toward the over 1.7 million cars the company has handed over to customers annually since 2022.
However, the Model S and Model X have remained in production because of their high-end performance and flagship status; they are truly two vehicles that are premium offerings and do not hold major weight toward Tesla’s future goals.
On Wednesday, during the Q4 2025 Earnings Call, Musk confirmed that Tesla would bring closure to the two models, ending their production and making way for the manufacturing efforts of the Optimus robot:
“It is time to bring the Model S and Model X programs to an end with an honorable discharge. It is time to bring the S/X programs to an end. It’s part of our overall shift to an autonomous future.”
Musk said the production lines that Tesla has for the Model S and Model X at the Fremont Factory in Northern California will be transitioned to Optimus production lines that will produce one million units per year.

Tesla will continue to service Model S and Model X vehicles, but it will officially stop deliveries of the cars in Q2, as inventory will be liquidated. When they’re gone, they’re gone.

Tesla has been making moves to sunset the two vehicles for the better part of one year. Last July, it stopped taking any custom orders for vehicles in Europe, essentially pushing the idea that the program was coming to a close soon.
Musk said back in 2019:
“I mean, they’re very expensive, made in low volume. To be totally frank, we’re continuing to make them more for sentimental reasons than anything else. They’re really of minor importance to the future.”
That point is more relevant than ever as Tesla is ending the production of the cars to make way for Optimus, which will likely be Tesla’s biggest product in the coming years.
Musk added during the Earnings Call on Wednesday that he believes Optimus will be a major needle-mover of the United States’ GDP, as it will increase productivity and enable universal high income for humans.

Earnings call updates
The following are live updates from Tesla’s Q4 and FY 2025 earnings call. I will be updating this article in real time, so please keep refreshing the page to view the latest updates on this story.
16:25 CT – Good day to everyone, and welcome to another Tesla earnings call live blog. There’s a lot to unpack from Tesla’s Q4 and FY 2025 update letter, so I’m pretty sure this earnings call will be quite interesting.
16:30 CT – The Q4 and FY 2025 earnings call officially starts. IR exec Travis Axelrod opens the call. Elon and other executives are present.
16:30 CT – Elon makes his opening statement and explains why Tesla changed its mission to “Amazing Abundance.” “With the continued growth of AI and robotics, I think we’re headed towards a future of universal high income,” Musk said, adding that along the way, Tesla will still be improving its products while keeping the environment safe and healthy.
16:34 CT – Elon noted that the first steps for this future are happening this year, thanks to Tesla’s autonomy and robotics programs, which will be launching and ramping this year. He also highlighted that Tesla will be making major investments this year, though the company will be very strategic when it comes to its funding. “I think it makes a ton of strategic sense,” Musk said.
16:36 CT – Elon also announces the end of the Model S and Model X programs “with an honorable discharge.” If you’re interested in buying a Model S or X, it’s best to do it now, Musk said. The Model S and Model X factory in Fremont will be replaced by an Optimus line. “It’s slightly sad, but it is time to bring the S and X program to an end. It’s part of our overall shift to an autonomous future,” Musk said.
16:38 CT – Elon discusses how Unsupervised FSD is now starting for the Robotaxi service. He noted that these Unsupervised Robotaxis don’t have any chase cars as of yesterday. He reiterated Tesla’s plans for owners to be able to add their own vehicles to the Robotaxi fleet. Autonomy target for the end of the year is about a quarter or half of the United States, Musk said.
16:41 CT – Elon noted that the Tesla Energy team is absolutely killing it. He also stated that Tesla expects its Energy business to continue growing, and that the “solar opportunity is underrated.”
16:43 CT –Elon also added that Tesla Optimus 3 will be unveiled in about three months, probably. The Model S and Model X line in Fremont will be a million-unit Optimus production line. Looks like Optimus is really coming out of the gate with large, meaningful volumes. “The normal S curve for manufacturing ramps is longer for Optimus,” Musk stated. “Long term, I think Optimus will have a significant impact on the US GDP.”
16:44 CT – Elon closes his opening statements with a sincere thanks to the Tesla team. He also noted that he feels fortunate to be able to work alongside such a talented workforce.
Elon ends his opening remarks with an optimistic prediction about the future.“The future is more exciting than you can imagine,” he concluded.
16:47 CT – Tesla CFO Vaibhav Taneja makes his opening remarks. He discusses several aspects of Tesla’s Q4 milestones. He noted that Tesla Energy achieved yet another gross profit record during the fourth quarter. There’s insane demand for the Megapack and Powerwall. Backlogs for these products are healthy this 2026. He also noted that Tesla ended 2025 with a bigger vehicle order backlog compared to recent years.
16:53 CT – Investor questions from Say begin. The first question is about Tesla’s expectations for the Robotaxi Network. Lars Moravy noted that it has the advantage of manufacturing and scale, and Tesla believes that the Robotaxi Network will significantly grow year over year. Elon highlighted that the Cybercab will be produced with no steering wheel or pedals. No fallback. Elon also noted that Tesla expects to produce more Cybercabs than all its other vehicles combined in the future.
16:51 CT – The next question is if Tesla still expects to launch new models, such as affordable cars. Lars Moravy noted that Tesla did release affordable variants last year, and Tesla is still pushing hard to lower its costs. That being said, Tesla is really pushing the Cybercab as its total addressable market is larger than consumer-owned cars. Lars also mentioned that Tesla will produce different vehicles for its Robotaxi services.
16:56 CT – Elon noted that eventually, Tesla will produce mostly autonomous cars. The exception would be the next-generation Roadster, which will be a true driver’s car.
17:03 CT – A question about Elon’s past comments about a potential next pickup truck was asked. Lars noted that the Cybertruck is still performing well in the electric pickup truck segment, though Tesla is known for flexibility. Elon added that Tesla will be transitioning the Cybertruck line to a fully autonomous vehicle line. He also stated that the Cybertruck is a useful vehicle. “An autonomous Cybertruck will be useful for that.”
17:10 CT – A question was asked about when FSD will be 100% Unsupervised. Elon noted that 100% Unsupervised FSD is already being used today, though only in the Austin Robotaxi program. Tesla is still being extremely careful with its rollout.
When asked about Tesla’s chip program, Elon noted that he feels pretty good about Tesla’s chip strategy. But in terms of selling Tesla’s chips outside Tesla, the company has to make sure it has enough chips for Optimus robots, data centers, and other programs first.
17:18 CT – Analyst questions begin. First up is Wolf Research. He asks about Tesla’s increasing Capex, specifically where the majority of it is going. The Tesla CFO noted that programs in six factories are going live this year, so that consumes Capex. The Optimus program also consumes a lot of resources. The growth of Tesla’s current capacity is also consuming a lot of resources. As for how these programs will be funded, the CFO pointed to Tesla’s massive war chest, as well as initiatives such as the Robotaxi Network.
17:21 CT – Morgan Stanley asks about Tesla’s xAI investment. The analyst asked about more information about how Tesla and xAI will work together. The CFO noted that this investment is part of Master Plan Part IV. Elon also mentioned some advantages for xAI’s technology for Tesla’s products, like Grok being used to manage a Robotaxi fleet or a group of Optimus robots.
17:24 CT – Barclays asks Elon about the constraints on memory. Does Tesla have any near term constraints for Tesla vehicles’ memory? Elon responded that the Tesla AI computer is already very compute and memory-efficient. The intelligence per gigabyte is important. Musk noted that Tesla is ahead of the industry by an order of magnitude or more.
17:29 CT – Cannacord asks about startups from China entering the humanoid market. What competitive advantage does Optimus have compared to these rivals? Elon stated that he believes China will be a key competitor in the humanoid robot market. China will be the toughest competitor for Tesla. That being said, Elon noted that Tesla believes Optimus will be ahead in real-world intelligence, electromechanical dexterity, and hand design.
