SpaceX will launch its Mars spaceship into orbit as early as 2020
First spaceship prototype already under construction
Speaking on a launch industry round-table at the Satellite 2018 conference, SpaceX President and COO Gwynne Shotwell revealed that the company intends to conduct the first orbital launches of BFR as early as 2020, with suborbital spaceship tests beginning in the first half of 2019.
Only six months after CEO Elon Musk first debuted the Interplanetary Transport System in Adelaide, Australia, a flood of recent comments from both executives have made it overwhelmingly clear that SpaceX intends to have its first spaceship ready for short suborbital test flights at the beginning of 2019. Considering Musk’s unprovoked acknowledgment at SXSW 2018 of his tendency towards overly optimistic timelines, the repeated affirmations of BFS test flights beginning in 2019 and now an orbital launch of the full BFR booster and ship in 2020 hold a fair deal more water than they did in 2017.

Breaking it down
These past few weeks have been filled with a number of similar statements from SpaceX executives like Shotwell, Musk, and others; all focused in part on the company’s next-generation launch vehicle, BFR (Big __ Rocket). Composed of a single massive booster and an equally massive second stage/spaceship (BFS), the rocket is meant to enable the affordable expansion of permanent human outposts on Mars and throughout the inner solar system by making good on the decades-old promise of fully reusable launch vehicles.
In order to succeed, the company will need to solve the problems that NASA and its Shuttle contractors never could.

To an extent, SpaceX has already matured the principles and technologies needed to reliably recover and reuse the booster stage of two-stage rockets, demonstrated by their incredible success with Falcon 9.
BFR is a whole different animal, partly owing to its massive size, huge thrust, and new propellant and tankage systems, but those problems are more technical than conceptual. SpaceX already knows how to reuse boosters, and that will apply to BFR once its several technological hurdles have been overcome. Designing and building the orbital spaceship (BFS), however, will undoubtedly be the most difficult task SpaceX has yet to take on. The safety and cost records of the only other orbital-class reusable second stage in existence, the Space Shuttle, are at least partially indicative of the difficulty of the challenges ahead of SpaceX.
In order to succeed, the company will need to solve the problems that NASA and its Shuttle contractors never could – they will need to build an orbital, crewed spaceship that can be reused with minimal refurbishment, can launch for little more than the cost of its propellant, and does so with safety and reliability comparable to the records of modern commercial airliners – perhaps the safest form of transport humans have ever created.

Rockets do not easily lend themselves to such incredible standards of safety or reliability – airliners average a single death per 16 million flights – but SpaceX will need to reach similar levels of reusability and reliability if they hope to enable even moderately affordable spaceflight or Earth-to-Earth transport by rocket. Still, there can be little doubt that SpaceX employs some of the absolute best engineering expertise to have ever existed in the US, and their extraordinary personal investment in the company’s goal of making humanity multi-planetary bode about as well as could be asked for such an ambitious endeavor. According to Musk and Shotwell, the first spaceship is already being built and suborbital tests will begin as soon as 2019, while full-up orbital launches – presumably involving both the booster and spaceship – might occur just a single year later in 2020.

Musk: People have told me that my timelines historically have been optimistic. I am trying to recalibrate. What I do know is we are building the first ship. We will be able to do do short flights in the first half of next year. It's a big booster and ship. Saturn V thrust x2.

It appears that we will find out sooner, rather than later, if SpaceX has truly found a way to lower the cost to orbit by several orders of magnitudes. Follow us for live updates, behind-the-scenes sneak peeks, and a sea of beautiful photos from our East and West coast photographers.

Tesla confirms that work on Dojo 3 has officially resumed
“Now that the AI5 chip design is in good shape, Tesla will restart work on Dojo 3,” Elon Musk wrote in a post on X.
Tesla has restarted work on its Dojo 3 initiative, its in-house AI training supercomputer, now that its AI5 chip design has reached a stable stage.
Tesla CEO Elon Musk confirmed the update in a recent post on X.
Tesla’s Dojo 3 initiative restarted
In a post on X, Musk said that with the AI5 chip design now “in good shape,” Tesla will resume work on Dojo 3. He added that Tesla is hiring engineers interested in working on what he expects will become the highest-volume AI chips in the world.
“Now that the AI5 chip design is in good shape, Tesla will restart work on Dojo3. If you’re interested in working on what will be the highest volume chips in the world, send a note to AI_Chips@Tesla.com with 3 bullet points on the toughest technical problems you’ve solved,” Musk wrote in his post on X.
Musk’s comment followed a series of recent posts outlining Tesla’s broader AI chip roadmap. In another update, he stated that Tesla’s AI4 chip alone would achieve self-driving safety levels well above human drivers, AI5 would make vehicles “almost perfect” while significantly enhancing Optimus, and AI6 would be focused on Optimus and data center applications.
Musk then highlighted that AI7/Dojo 3 will be designed to support space-based AI compute.
Tesla’s AI roadmap
Musk’s latest comments helped resolve some confusion that emerged last year about Project Dojo’s future. At the time, Musk stated on X that Tesla was stepping back from Dojo because it did not make sense to split resources across multiple AI chip architectures.
He suggested that clustering large numbers of Tesla AI5 and AI6 chips for training could effectively serve the same purpose as a dedicated Dojo successor. “In a supercomputer cluster, it would make sense to put many AI5/AI6 chips on a board, whether for inference or training, simply to reduce network cabling complexity & cost by a few orders of magnitude,” Musk wrote at the time.
Musk later reinforced that idea by responding positively to an X post stating that Tesla’s AI6 chip would effectively be the new Dojo. Considering his recent updates on X, however, it appears that Tesla will be using AI7, not AI6, as its dedicated Dojo successor. The CEO did state that Tesla’s AI7, AI8, and AI9 chips will be developed in short, nine-month cycles, so Dojo’s deployment might actually be sooner than expected.

Elon Musk’s xAI brings 1GW Colossus 2 AI training cluster online
Elon Musk shared his update in a recent post on social media platform X.
xAI has brought its Colossus 2 supercomputer online, making it the first gigawatt-scale AI training cluster in the world, and it’s about to get even bigger in a few months.
Elon Musk shared his update in a recent post on social media platform X.
Colossus 2 goes live
The Colossus 2 supercomputer, together with its predecessor, Colossus 1, are used by xAI to primarily train and refine the company’s Grok large language model. In a post on X, Musk stated that Colossus 2 is already operational, making it the first gigawatt training cluster in the world.
But what’s even more remarkable is that it would be upgraded to 1.5 GW of power in April. Even in its current iteration, however, the Colossus 2 supercomputer already exceeds the peak demand of San Francisco.
Commentary from users of the social media platform highlighted the speed of execution behind the project. Colossus 1 went from site preparation to full operation in 122 days, while Colossus 2 went live by crossing the 1-GW barrier and is targeting a total capacity of roughly 2 GW. This far exceeds the speed of xAI’s primary rivals.
Funding fuels rapid expansion
xAI’s Colossus 2 launch follows xAI’s recently closed, upsized $20 billion Series E funding round, which exceeded its initial $15 billion target. The company said the capital will be used to accelerate infrastructure scaling and AI product development.
The round attracted a broad group of investors, including Valor Equity Partners, Stepstone Group, Fidelity Management & Research Company, Qatar Investment Authority, MGX, and Baron Capital Group. Strategic partners NVIDIA and Cisco also continued their support, helping xAI build what it describes as the world’s largest GPU clusters.
xAI said the funding will accelerate its infrastructure buildout, enable rapid deployment of AI products to billions of users, and support research tied to its mission of understanding the universe. The company noted that its Colossus 1 and 2 systems now represent more than one million H100 GPU equivalents, alongside recent releases including the Grok 4 series, Grok Voice, and Grok Imagine. Training is also already underway for its next flagship model, Grok 5.

Tesla AI5 chip nears completion, Elon Musk teases 9-month development cadence
The Tesla CEO shared his recent insights in a post on social media platform X.
Tesla’s next-generation AI5 chip is nearly complete, and work on its successor is already underway, as per a recent update from Elon Musk.
The Tesla CEO shared his recent insights in a post on social media platform X.
Musk details AI chip roadmap
In his post, Elon Musk stated that Tesla’s AI5 chip design is “almost done,” while AI6 has already entered early development. Musk added that Tesla plans to continue iterating rapidly, with AI7, AI8, AI9, and future generations targeting a nine-month design cycle.
He also noted that Tesla’s in-house chips could become the highest-volume AI processors in the world. Musk framed his update as a recruiting message, encouraging engineers to join Tesla’s AI and chip development teams.
Tesla community member Herbert Ong highlighted the strategic importance of the timeline, noting that faster chip cycles enable quicker learning, faster iteration, and a compounding advantage in AI and autonomy that becomes increasingly difficult for competitors to close.
AI5 manufacturing takes shape
Musk’s comments align with earlier reporting on AI5’s production plans. In December, it was reported that Samsung is preparing to manufacture Tesla’s AI5 chip, accelerating hiring for experienced engineers to support U.S. production and address complex foundry challenges.
Samsung is one of two suppliers selected for AI5, alongside TSMC. The companies are expected to produce different versions of the AI5 chip, with TSMC reportedly using a 3nm process and Samsung using a 2nm process.
Musk has previously stated that while different foundries translate chip designs into physical silicon in different ways, the goal is for both versions of the Tesla AI5 chip to operate identically. AI5 will succeed Tesla’s current AI4 hardware, formerly known as Hardware 4, and is expected to support the company’s Full Self-Driving system as well as other AI-driven efforts, including Optimus.
