SpaceX CEO Elon Musk says Starship (BFS) hop tests could start in early 2019
SpaceX CEO Elon Musk has taken to Twitter to share an unexpected wealth of detail about the “radical” and largely unpublicized design changes the company’s Starship and Super Heavy (BFS & BFB) have undergone in 2018.
Beside information ranging from discussions of metallurgy to overall design philosophy and comparisons, the eccentric CEO also offered the most concrete target yet for the beginning of prototype spaceship (BFS/Starship) hop tests in South Texas – “March/April [2019]”.
I will do a full technical presentation of Starship after the test vehicle we’re building in Texas flies, so hopefully March/April

On one hand, this expeditious new testing schedule – acknowledged by Musk himself to be “much sooner than expected” – is a thrilling prospect, given that it implies that a nearly full-scale prototype of Starship (or something vaguely approximating the spacecraft) could take its first baby steps into the air as early as the first quarter of 2019. On the other hand, however, this is an almost bafflingly large schedule change considering that SpaceX President and COO Gwynne Shotwell asserted that a prototype of BFS (now Starship) could begin “hopping” by late 2019, speaking in September 2018.
Shotwell: think we’ll be “hopping” the second stage of BFR (the BFS) late next year. #DARPA60

Schedules (especially aerospace program schedules) do certainly tend to be chaotic and jumpy, but it’s almost inconceivable that any given project – regardless of the scope or scale – could wind up reaching completion nine months earlier than previously forecasted without suffering one or several dramatic compromises, typically involving lower-fidelity testing and prototypes or watered-down deliverables. It’s unclear if BFR has suffered the same fate, but – to put it lightly – the South Texas sight greeting the eyes of close followers of SpaceX’s BFR program is downright unbelievable.
BFWhat?!
Given the very recent and conspicuous additions of triangular appendages that look precisely like rudimentary fins and an obvious nose cone assembly, the only possible conclusion to draw from photos of SpaceX’s Boca Chica facilities taken in the last week or two is that the company (and/or contractors) are busy building something related to Starship. At least in these early stages, the… thing being built could be best described as what might come to mind if you asked an imaginative kid to build a full-scale sculpture of Tintin’s spaceship on a budget of maybe $500,000.

More likely than not, this could be a case of things being more than they seem. To most, it may almost look like an elaborate prank, but that assumes that we know the full story and have a decent working understanding of aerospace prototyping. For the vast majority of us, that is simply not the case – what looks like a spade is probably not a spade.
At the end of the day, the most basic of observations – that this purported ‘Starship prototype’ will begin hop tests with extraordinarily powerful Raptor engines installed as few as three months from now – suggest that this spooky metal contraption will be used to conduct the most basic of Starship tests. As such, it will probably never travel much faster than Falcon 9’s Grasshopper and F9R predecessors, which tended to gently accelerate from the ground to as high as a kilometer or two before slowly heading back down for a powered landing.

Given that SpaceX has already refined this complex and challenging task to a reliable science with Falcon 9 and Merlin 1D, it’s unclear why a very similar test campaign would be of serious value to the company without simultaneously testing full-fidelity control surfaces (fins), exotic new stainless steel propellant tank technologies, and more. Perhaps SpaceX just really wants to ensure that Starship will be capable of landing and taking off from an unprepared and angled surface of the type it could (will?) experience on Mars. Maybe the company simply wants to have a bare-minimum flying platform capable of testing and refining multi-engine configurations of Raptor.

All that can be said for sure at the moment is that the public simply does not have the full story to explain the moderately shocking activity going on in Boca Chica. Musk did state that he would provide another technical update on the status of Starship and the BFR program as a whole in the first half of 2019, but only after the first Starship hopper flights have begun. It would seem that those on the sidelines will simply have to wallow in confusion and wild speculation for another ~3-4 months at minimum, hopefully only going moderately insane as a result.
In the meantime, copious thanks are owed to NASASpaceflight members bocachicagal and Nomadd for their relentless and thorough coverage of SpaceX’s activities in the obscure far south of the Texan coast, as well as their courteous permission for media outlets like Teslarati to republish their photos. Cheers!

Tesla Cybercab display highlights interior wizardry in the small two-seater
Photos and videos of the production Cybercab were shared in posts on social media platform X.
The Tesla Cybercab is currently on display at the U.S. Department of Transportation in Washington, D.C., and observations of the production vehicle are highlighting some of its notable design details.
Photos and videos of the production Cybercab were shared in posts on social media platform X.
Observers of the Cybercab display unit noted that the two-seat Robotaxi provides unusually generous legroom for a vehicle of its size. Based on the vehicle’s video, the compact two-seater appears to offer more legroom than Tesla’s larger vehicles such as the Model Y, Model X, and Cybertruck.
The Cybercab’s layout allows Tesla to dedicate nearly the entire cabin to passengers. The vehicle is designed without a steering wheel or pedals, which helps maximize interior space.
Footage from the display also highlights the Cybercab’s large center screen, which is positioned prominently in front of the passenger bench. The display appears intended to provide entertainment and ride information while the vehicle operates autonomously.
Images of the vehicle also show an additional camera integrated into the Cybercab’s C-pillar. The extra camera appears to expand the vehicle’s field of view, which would be useful as Tesla works toward fully unsupervised Full Self-Driving.
Tesla engineers have previously explained that the Cybercab was designed to be highly efficient both in manufacturing and in operation. Cybercab Lead Engineer Eric E. stated in 2024 that the Robotaxi would be built with roughly half the number of parts used in a Model 3 sedan.
“Two seats unlocks a lot of opportunity aerodynamically. It also means we cut the part count of Cybercab down by a substantial margin. We’re gonna be delivering a car that has roughly half the parts of Model 3 today,” the Tesla engineer said.
The Tesla engineer also noted that the Cybercab’s cargo area can accommodate multiple golf bags, two carry-on suitcases, and two full-size checked bags. The trunk can also fit certain bicycles and a foldable wheelchair depending on size, which is quite impressive for a small car like the Cybercab.

Elon Musk’s xAI wins permit for power plant supporting AI data centers
The development was reported by CNBC, citing confirmation from the Mississippi Department of Environmental Quality (MDEQ).
Mississippi regulators have approved a permit allowing Elon Musk’s artificial intelligence company xAI to construct a natural gas power plant in Southaven. The facility is expected to support the company’s expanding AI infrastructure tied to its Colossus data center operations near Memphis.
The development was reported by CNBC, citing confirmation from the Mississippi Department of Environmental Quality (MDEQ).
According to the report, regulators “voted to approve the permit” of xAI subsidiary MZX Tech LLC to construct a power plant featuring 41 natural gas-burning turbines “after careful consideration of all public comments and community concerns.”
The Mississippi Department of Environmental Quality stated that the permit followed a regulatory review process that included public comments and community input. Jaricus Whitlock, air division chief for the MDEQ, stated that the project met all applicable environmental standards.
“The proposed PSD permit in front of the board today not only meets all state and federal permitting regulations, but goes above and beyond what is required by law. MDEQ and the EPA agree that not a single person around our facilities will be exposed to unhealthy levels of air pollution,” Whitlock stated.
The planned facility will help provide electricity for xAI’s AI computing infrastructure in the Memphis region.
The Southaven project forms part of xAI’s efforts to scale computing capacity for its artificial intelligence systems.
The company currently operates two major data centers in Memphis, known as Colossus 1 and Colossus 2, which provide computing power for xAI’s Grok AI models. xAI is also planning to build another large data center in Southaven called Macrohardrr, which would be located in a warehouse previously used by GXO Logistics.
Large-scale AI training requires substantial computing power and electricity, prompting technology companies to develop dedicated energy infrastructure for their data centers.
SpaceX President Gwynne Shotwell previously stated that xAI plans to develop 1.2 gigawatts of power capacity for its Memphis-area AI supercomputer site as part of the federal government’s Ratepayer Protection Pledge. The commitment was announced during an event with United States President Donald Trump.
“As part of today’s commitment, we will take extensive additional steps to continue to reduce the costs of electricity for our neighbors. xAI will therefore commit to develop 1.2 GW of power as our supercomputer’s primary power source. That will be for every additional data center as well. We will expand what is already the largest global Megapack power installation in the world,” Shotwell said.
“The installation will provide enough backup power to power the city of Memphis, and more than sufficient energy to power the town of Southaven, Mississippi where the data center resides. We will build new substations and invest in electrical infrastructure to provide stability to the area’s grid.”

Tesla China teases Optimus robot’s human-looking next-gen hands
The image was shared by Tesla AI’s account on Weibo and later reposted by Tesla community members on X.
A new teaser shared by Tesla’s China team appears to show a pair of unusually human-like hands for Optimus.
The image was shared by Tesla AI’s account on Weibo and later reposted by Tesla community members on X.
As could be seen in the teaser image, the new version of Optimus’ hands features proportions and finger structures that look strikingly similar to those of a human hand. Their appearance suggests that they might have dexterity approaching that of a human hand.
If the image reflects a new generation of Optimus’ hands, it could indicate Tesla is continuing to refine one of the most critical components of its humanoid robot.
Hands are widely viewed as one of the most difficult engineering challenges in robotics. For Optimus to perform complex real-world work, from manufacturing tasks to household activities, its hands would need to be the best in the industry.
Elon Musk has repeatedly described Optimus as Tesla’s most important long-term product. In posts on social media platform X, Musk has stated that Optimus could eventually become the first real-world Von Neumann machine.
In theory, a Von Neumann machine is a self-replicating system capable of building copies of itself using available materials. The concept was originally proposed by mathematician John von Neumann in the mid-20th century.
“Optimus will be the first Von Neumann machine, capable of building civilization by itself on any viable planet,” Musk wrote in a post on X.
If Optimus is expected to carry out complex work autonomously in the future, high levels of dexterity will likely be essential. This makes the development of advanced robotic hands a key step towards Musk’s long-term expectations for the product.
