Elon Musk teases an update to SpaceX’s Mars architecture later this year
Elon Musk and SpaceX are aiming to provide a second update on the company’s Mars architecture plans in late September of this year, likely at the 2017 International Astronautical Congress (IAC) in Adelaide, Australia.
While 2017 has been extraordinarily busy and successful for SpaceX thus far, it has also been a somewhat quiet year for Mars and the technology being developed to colonize it affordably. There was a brief flurry of social media information focused on the testing of the ITS carbon composite test tank revealed at the 2016 IAC, with a few pictures and a video of its transport. This activity, as well as Elon Musk’s Ask Me Anything on /r/SpaceX, occurred a month or two after the 2016 IAC, in October and November.

The only concrete information revealed about SpaceX’s Mars ambitions in 2017 have so far been distributed by Musk over Twitter and in an interview of SpaceX President and COO Gwynne Shotwell a few weeks ago. Musk offered tentative time frames for a possible update of the Mars architecture, stating that he believed it dealt with the far more crucial challenge of how to finance such a large endeavor’s significant R&D costs.

During his 2016 reveal, Musk estimated that something like $10 billion would be required to complete development and initial construction of the Raptor engine and ITS test articles. While it is believed that SpaceX has at least several hundred million dollars of liquid capital available, growing several billion dollars of capital is a much greater challenge that will likely require a different methodology than those typically employed by Musk.
Shotewell also discussed SpaceX’s Mars ambitions off and on during an hour-long interview on The Space Show. Of general interest, she mentioned that the current team working on Mars-related research and development was “tiny”, but that it would become a drastically more resource-intensive priority as the company completes work on the fifth and somewhat final “Block” of Falcon 9 and finishes the work necessary to begin routinely conducting Commercial Crew missions. Shotwell gave a timeline of “soon” for the beginning of Block 4 flights and “end of year” for the introduction of Block 5, which is intended to significantly increase the reusability of Falcon 9 (titanium grid fins are a feature of this strategy). Barring delays or setbacks for SpaceX, this implies that SpaceX will begin aggressively pursuing the concrete development of their Mars architecture as soon as the latter months of 2018 or sometime in 2019.

More specifically, however, Shotwell said that the Raptor test article revealed at the Guadalajara IAC has since conducted “dozens” of tests and is now more seriously considering the engine’s potential utility aboard Falcon 9. The current subscale Raptor components are approximately half the size of the final, operational design, and the need to scale up by as little as a factor of 2 should make the realization of the final design considerably less difficult, and make the testing of the current Raptor far more demonstrative of the operational engine. The exploration of vacuum Raptor as the engine of an upgraded second stage for Falcon 9 would further allow for true on-orbit testing of Raptor, and increasing the performance of S2 would allow for greater flexibility in exploring second stage reuse. Musk and Shotwell have expressed interest in this, particularly given that the second stage is approximately 30% of the cost of every Falcon 9, thus capping any potential cost savings first stage (and fairing) reuse may bring. If SpaceX wishes to lower the cost of launches by a factor of 10 to 100 and bring to life any form of the Mars architecture revealed in Guadalajara, they will have to develop second stage reusability that it is both as rapid, functional, and complete as they soon hope to make first stage reuse.
A fully reusable Falcon 9 would offer the company more cost-effective ways to launch their own profit-driving internet constellation, and could also simply provide deeper profit margins for their main business of commercial launches. However, with Musk having already publicly acknowledged that reusability cost SpaceX approximately $1 billion to develop, SpaceX is certainly already considering the plausibly diminishing returns of diverting more funds and human resources into the continued development of Falcon 9. The most likely outcome is almost certainly some combination of the above goals, whereby SpaceX would delay their Mars exploration timeline by several years and concurrently pursue Falcon 9 second stage reuse and the initial test article development for their Mars architecture, as well as exploring the challenges and intricacies of human spaceflight and deep space exploration with Dragon v2.

Of note, the only known major testing event in 2017 related to SpaceX’s Mars program was observed by a SpaceX fan in February of this year. After successful November 2016 tests of the carbon composite tank in northern Washington state, fans noted that the tank had made an outdoors appearance once more in early February 2017. SpaceX mentioned on Instagram that the following test, the one SpaceX was preparing for in February, was a full cryo test of the tank, meaning that it involved actual high-pressure, supercooled liquid oxygen. Another fan noted several days later that the barge SpaceX was testing the tank aboard returned to port empty, and later observed what looked like several large pieces of the tank test article that reportedly had to be recovered from the sound by divers. The logical conclusion is that the tank was destroyed during its second phase of testing, but the crucial and currently unknown fact of the matter is whether the failure was a result of intentionally destructive testing or defects in what was effectively an experimental engineering article. Further SpaceX talks later this year will likely reveal some level of detail as to what transpired in the testing of that prototype carbon composite tank.
Reasoned speculation aside, the latter months of 2017 have multiple talks, speeches, and hearings planned by SpaceX members like Elon Musk and Tim Hughes, and information on SpaceX’s Mars ambitions and other future prospects will almost certainly be offered. Hughes is to attend a hearing at 9am EST on July 13th for the U.S. Senate on commercial space and will be testifying on the subject as a representative and employee of SpaceX. Just under a week later, Elon Musk is scheduled to be the main keynote speaker at the 2017 ISS R&D Conference. His talk is set to begin at 12:30pm EST on July 19th. A handful of months after that, as mentioned above, Musk may also provide a detailed update on SpaceX’s Mars architecture at the 2017 International Astronautical Congress.
In other words, on top of an aggressive 12 possible launches between August and the end of December, SpaceX fans also can look forward to details, photos, and possibly even more about the company’s Mars efforts over the next several months.

Elon Musk just confirmed the Tesla and SpaceX merger step everyone was waiting for
Tesla and SpaceX formed special committees to weigh a merger, and Elon Musk supports it.
Elon Musk confirmed Tuesday that Tesla and SpaceX have each formed special committees of independent directors to study a possible merger, the first formal step toward combining the two companies after months of speculation.
Musk made the disclosure during SpaceX’s third quarter earnings call. “Both SpaceX and Tesla have formed special committees to discuss this idea at the request of shareholders,” he said. “Because I’m a conflicted party, I can’t actually be in the discussions of the special committees.” He described the setup as “an odd kabuki dance where two groups of people are talking and I can’t be in the conversation.”
Musk did not hide where he stands. “Do I think it would be a good idea? Yes,” he said, pointing to shared work on super intelligence software, chip design, the Terafab facility in Austin, robotics, mass to orbit and connectivity. “I do think there’s a lot of merit to combining the companies as we are pretty much in the super intelligence singularity.”
He also tried to cool expectations. The committees have not agreed on terms for any transaction, and Musk said assuming a merger is a certainty “would be overstating it.” Any deal would go to shareholders, and on the Tesla side it would need approval from 50 percent of all outstanding shares, not just the shares that are voted. Musk called that “quite a high hurdle.”
That bar has tripped Tesla up before. The company’s 2025 attempt to declassify its board won support from only 39.4 percent of outstanding shares and failed. Musk’s own voting stake sits near 20 percent after he exercised his 2018 options in June, so a deal would need broad backing from institutions and a retail base that often leaves votes uncast.
Timing is another open question. Tesla filed its proxy statement Monday for its December 3 annual meeting, and the ballot has only three items: director elections for Musk, Robyn Denholm and JB Straubel, a say on pay vote and auditor ratification. Barclays analyst Dan Levy had argued that an announcement would need to land by late October or early November to make the annual meeting, as Teslarati noted in its SpaceX earnings preview. With no terms agreed, any vote would likely require its own special meeting.
Elon Musk gives his most telling Tesla-SpaceX merger conversation yet
Musk has been edging toward this for weeks. At the All-In Summit in September, he asked “who can imagine what action one might take when there’s so much close collaboration,” Teslarati reported. Last week’s Roadster unveil, built around SpaceX derived cold gas thrusters, pushed the talk further. The two companies already share the Terafab chip project, and Tesla holds a small SpaceX stake that came from its earlier investment in xAI.
SpaceX brought strong numbers to the conversation. It reported Q3 revenue of $14.58 billion, up 161 percent year over year, with its Super Intelligence segment now its largest at $7.56 billion. A higher SpaceX valuation would shape any exchange ratio Tesla holders are offered.
Tesla reports its own third quarter results after the close on Wednesday, October 21. Investors had already ranked merger timing among the top retail questions for SpaceX’s call, and the committees will almost certainly come up again on Tesla’s.

SpaceX delivers blockbuster Q3 results as Super Intelligence segment booms
SpaceX reported its third-quarter 2026 financial results on October 20, posting the company’s first solidly profitable quarter since going public earlier in the year under the ticker $SPCX.
Revenue reached $14.58 billion, up 161 percent year-over-year from $5.6 billion, and well ahead of consensus estimates in the $12.7 to $12.9 billion range. The results highlight a rapid shift in SpaceX’s center of gravity toward artificial intelligence/super intelligence, while Starlink and traditional space operations continue to show robust progress.
Here are the key financial results for the quarter:
- Revenue of $14.58 billion (+161% YoY)
- Adjusted EBITDA of $8.8 billion (+306% YoY)
- GAAP net income of $4.4 billion (versus a $1.1 billion net loss in the prior-year quarter)
- Adjusted EPS of approximately $0.35 (versus roughly $0.13–0.16 expected)
- Income from operations of $2.8 billion
The AI/SI segment generated $7.56 billion in revenue, an 830 percent year-over-year increase, making it the company’s largest segment for the first time. Growth was primarily driven by the activation of major cloud services agreements, the integration of Cursor (acquired earlier in 2026), and rising usage of Grok models and the newly introduced Grok Bot personal agent.
🚨 SpaceX just reported earnings! Here are some highlights:
Financial:
Revenue $14.58B (+161% YoY) vs. consensus ~$12.7–12.9B
Adjusted EBITDA $8.8B (+306% YoY)
GAAP net income $4.4B (vs. prior-year loss; first solidly profitable quarter post-IPO)
Adjusted EPS ~$0.35 vs. ~$0.13–0.16 expectedSegments:
Super Intelligence (SI, formerly AI): $7.56B (+830% YoY) — now the largest segment, driven by cloud contracts, Cursor, and Grok.
Connectivity (Starlink): $5.25B (+69% YoY).
Space: $1.77B.Other highlights:
Starlink subscribers: 13.6M (+89% YoY).
Nameplate compute: 1.7 GW.
Capex: $19.6B (majority AI infrastructure).
Cash & marketable securities: ~$90B.
First revenue-generating Starship mission (26 V3 Starlink satellites, ~10× Falcon 9 downlink capacity per launch).— TESLARATI (@Teslarati) October 20, 2026
SI adjusted EBITDA reached $5 billion, and nameplate compute capacity stood at 1.7 GW at quarter-end, up from 1.4 GW in June and 0.6 GW a year earlier. Capital expenditures totaled $19.6 billion, with the majority allocated to AI infrastructure, including continued expansion of the Colossus facilities.
The Connectivity segment, which primarily surrounds Starlink, produced $5.25 billion in revenue, a 69 percent year-over-year and 22 percent sequentially. These are pleasant results to see and expected, considering how many airlines have adopted Starlink over the past year.
Starlink consumer subscribers reached 13.6 million, an 89 percent increase from the prior year, and a sequential gain of 1.6 million. Consumer average revenue per user improved to $69. Meanwhile, Enterprise and Government revenue also grew strongly, and Starlink is now installed on more than 3,800 aircraft, making internet more accessible and better performing than previous options.
The Space segment also performed well and contributed $1.77 billion in revenue, up 6 percent year-over-year and 84 percent sequentially. A major milestone was the successful first revenue-generating Starship mission (Flight 14), which deployed 26 V3 Starlink satellites. Those satellites added roughly 10 times the downlink capacity of a typical Falcon 9 Starlink launch.
SpaceX completed 12 customer launches during the quarter, including NASA’s Nancy Grace Roman Space Telescope mission, and continued to grow its backlog of crewed, national security, and commercial flights.
CFO commentary noted that the combination of launch leadership, recurring Starlink revenue, and rapid SI expansion is producing meaningful operating leverage.
The company ended the quarter with roughly $90 billion in cash and marketable securities, providing substantial resources for ongoing investment while targeting an investment-grade balance sheet. Sequential revenue nearly doubled from the $7.81 billion reported in the second quarter, illustrating the pace of the AI-driven acceleration. Things are looking strong for SpaceX.
What’s incredibly striking is the fact that SI has grown to be larger than the rest of the company in such a short amount of time. CEO Elon Musk said on the earnings call that Grok Bot is the “fastest-growing product I’ve ever seen,” so it seems that it could be a true keystone of SpaceXSI over the next few years.
Investor's Corner
SpaceX reports its second earnings today: here’s what to expect
SpaceX (NASDAQ: SPCX) will report its second public earnings call today since its IPO earlier this year, and there are a few things we expect to hear about, as well as Wall Street analysts, who have already outlined their expectations for the call.
Wall Street analysts have a consensus of $12.72 billion in revenue and an earnings per share (EPS) of $0.13. These are broken down into three sectors: Space, Connectivity, and AI/SI, which are perceived in this way:
- Space: $1.41 billion
- Connectivity: $4.84 billion
- AI/SI: $6.47 billion
Other outlets cluster near $12.8 or $12.9 billion in revenue and $0.14 – $0.15 EPS. This implies a roughly 65 percent sequential growth from Q2’s $7.81 billion, driven mostly by AI/SI, with the first post-IPO positive EPS expected.
Here are the three things to watch for on the call:
AI Revenue Ramp and the $100B+ ARR target
AI is truly the swing factor for SpaceX, and analysts expect it to roughly double from Q2’s $2.56 billion and become about half of total revenue. Management previously guided to a $100 billion+ annualized run rate by December, including the Cursor acquisition, which was $60 billion, to close the quarter.
Listen for updates on SpaceX’s compute capacity, especially pertaining to its contracts with Google, Anthropic, and others, revenue per watt, any new deals, and Cursor’s early contribution.
Starlink/Connectivity Metrics and Mobile Expansion
Connectivity remains a main profit engine for SpaceX. Subscriber additions will be something to pay attention to, as Q2 ended at 12 million and previews are looking at 14 million for this quarter. Additionally, ARPU trends, enterprise and government growth, and any commentary on Starlink Mobile will be something to pay attention to, especially following the recent low-band spectrum deal and FCC-related constellation approvals.
Capex Trajectory, Cash Burn/FCF, and Starship/Operational Updates
Q2 capex of roughly $18.4 billion weighed on the stock. Investors will look to scrutinize Q3 spending levels, any guidance on the pace into Q4/2027, free cash flow, backlog, and liquidity. Operational color on Starship (Flight 14 milestones and Flight 15 timing/reusability progress), Falcon cadence, and government/NASA contracts are also in focus.
Of course, there will also be some speculation on the potential Tesla-SpaceX merger, but there was nothing mentioned in the company’s proxy it sent earlier this week.
SpaceX will report earnings after market close today and will stream the call on X.
