Relativity Space’s first 3D-printed rocket goes vertical for launch debut

Published

Relativity Space’s first 3D-printed Terran 1 rocket has rolled out to the startup’s Florida pad and been raised vertical ahead of its launch debut.

Founded in 2015, the private Los Angeles-based spaceflight company shipped its first complete rocket prototype to Florida in June 2022. Prior to that major milestone, Relativity qualified Terran 1’s orbital second stage at leased facilities located at NASA’s Stennis Space Center in southwest Mississippi, and – alongside a nosecone and interstage – arrived at Cape Canaveral Space Force Station (CCSFS) more or less ready to fly.

The last six months have been almost exclusively dedicated to testing Terran 1’s larger and more powerful first stage (booster) as thoroughly as possible. Instead of building a dedicated booster test stand in Mississippi, Relativity chose to modify Terran 1’s lone LC-16 launch pad for the crucial task. Ultimately, the startup was able to complete a large amount of booster testing on the ground, significantly increasing the odds that Terran 1 will perform as expected when it lifts off for the first time.

Beginning with cryogenic proofing, propellant loading, ‘spin starts,’ and several shorter static fire tests, Relativity’s first Terran 1 booster test campaign culminated with two long-duration static fires in September 2022. The final 57 and 82-second static fires weren’t quite the “full mission duration” tests Relativity had hoped for, but the company concluded that the data gathered was enough to clear the booster for flight.

According to Ellis, one of the most important insights gained from those tests was into Terran 1’s uncharacteristically complex autogenous pressurization system – unprecedented for such a small rocket. Generally speaking, orbital-class rockets store helium gas in small ultra-high-pressure tanks (COPVs) and use helium to pressurize their propellant tanks as they are drained of propellant. Autogenous pressurization refers to an alternative in which a portion of a rocket’s liquid oxidizer and fuel are turned into hot gas and injected back into their respective tanks to pressurize them.

Helium is extremely expensive and an unrenewable resource. In theory, autogenous pressurization – at the cost of being significantly more complex and finicky – can also reduce the amount of dry mass reserved for tank pressurization. While Terran 1 wasn’t able to complete a full-duration static fire, the tests it did complete showed Relativity that its autogenous pressurization systems are unlikely to be a problem in flight, mostly eliminating a major source of uncertainty.

Following the final 82 or 88-second static fire, Relativity returned Terran 1’s booster to LC-16’s hangar and shifted its focus to fully assembling the two-stage rocket and finishing the launch pad. In early December, the company announced that it had fully assembled the first Terran 1. Days later, the rocket was installed on the pad’s “Transporter Erector.” The T/E responsible for transporting the rocket and raising it vertical, but it also needs to connect the rocket to ground systems (propellant, power, comms, etc.) and hold it down before liftoff.

On or around December 6th, Terran 1 rolled out to the pad and was raised vertical soon after. According to Ellis, all that stands between Terran 1 and its first launch is a short integrated static fire test and a launch license from the Federal Aviation Administration (FAA). It’s impossible to say how long the FAA will take, but it’s likely that Relativity will be technically ready to launch just a handful of weeks from now.

Beyond building a relativity impressive rocket, Relativity’s claim to fame is large-scale 3D printing. The startup says that the first Terran 1 rocket – booster, upper stage, fairing, engines, and all – is 85% 3D-printed by mass and the largest single 3D-printed object ever built. Terran 1 reportedly weighs around 9.3 tons (20,500 lb) empty; will measure around 33 meters (110 ft) tall and 2.3 meters (7.5 ft) wide; and will produce around 90 tons (~200,000 lbf) of thrust at liftoff. The rocket is designed to launch 1.25 tons (~2750 lb) to low Earth orbit for $12 million

Tesla Semi lands the biggest electric truck deal in U.S. history

Tesla leads a record 2,500 truck order, but not every truck will be a Semi.

Tesla has landed the largest electric truck order in U.S. history. ZET SCALE, a new alliance of shippers and carriers, named Tesla its primary manufacturer on Tuesday for an initial order of 2,500 electric Class 8 trucks. The deal alone would nearly double the number of electric heavy trucks operating in the country.

According to the press release from Catalyst Mobility, the nonprofit formerly known as CALSTART, Kenworth, RIDE and Volvo were also selected as secondary manufacturers that carriers can pick if their operations call for it. No split between the four brands has been published, so the exact number of Semis in the order is not yet known.

Tesla won the top slot through a competitive request for proposals. The alliance, which Catalyst Mobility runs with the Smart Freight Centre, scored bidders on price, range, charging capability and production capacity. Pooling freight demand from founding shippers, including Microsoft and PepsiCo, let every truck maker bid lower than it would for a single fleet. “The Tesla Semi is designed for lower cost per mile operations than diesel,” said Dan Priestley, director of the Tesla Semi program, as noted in the press release.

The financing is built to pull in carriers who have avoided electric trucks. ZET Financial is issuing the purchase order for all 2,500 units and will place them with fleets through a fair market value lease. The trucks will be deployed over the next few years across 10 freight hubs in Los Angeles, Stockton, Bakersfield, Seattle and Tacoma, Houston, Dallas, San Antonio, Chicago, Atlanta, and the Newark and New York area. ZET SCALE says the first order is only the opening round, with a longer term goal of 10,000 trucks or more.

Even if Tesla ends up with only a majority share, it would still be the biggest Semi deal to date. Einride’s 500 unit order in August was the previous record, and WattEV’s 370 truck order in May was the largest California deal at the time. Einride’s CEO has since said he expects all 500 trucks delivered by the end of 2027.

The announcement lands two days before Tesla formally inaugurates its Semi factory in Nevada on September 24. The 1.7 million square foot plant sits next to Gigafactory Nevada’s 4680 cell lines and is designed for 50,000 trucks a year.

Tesla integrates Grok Bot into its vehicles for the ultimate personal assistant

Tesla has expanded Grok from an in-car chatbot into a hands-free work assistant. On September 22, Tesla officially launched Grok Bot capability, confirming that drivers can now manage email, calendars, files, chats, and tasks by voice and then hand more ambitious errands to the AI-fueled productivity cheat code.

Grok itself is built by xAI. The new car features split into two layers: Connectors link Grok to outside accounts. Grok Bot, currently limited to SuperGrok Heavy subscribers, can complete multi-step tasks such as placing a usual coffee order, booking a reservation, or scheduling an appointment. It truly puts the driver in a nearly complete hands-free driving and productivity setting, with ironically the only task truly requiring your hands being to touch the “Start Self-Driving” button.

We were granted access to Grok Bot’s Tesla integration a few weeks back, and we’ve been able to do a handful of things with it. On a handful of occasions, we’ve used it to order food and have it ready for pickup slightly later into the evening; we’ve managed to pick up groceries after a day of errands with Grok Bot, and outside of the car, it’s helped with budgeting and even my fantasy football draft.

Tesla shows another way to utilize it: in their demo, a driver says “Hey Grok,” asks the assistant to check an inbox, and hears that a message concerns a weekend reservation. Grok then scans the calendar, reports no conflicts, and confirms the Tahoe trip is clear. It can also add check-in details to a road-trip itinerary. The point is not novelty chat. It is keeping eyes on the road, or on Full Self-Driving, while the car handles the paperwork of a trip:

This Grok rollout is not a gadget add-on as much as it is Tesla’s thesis in software form: the car should stop being a machine you operate and start being a room you occupy.

Connectors and Grok Bot treat the cabin as an office that happens to move, and that has truly been Tesla’s intention for years now. The car has slowly become an extension of a home more than a vehicle. Inbox, calendar, groceries, takeout, and reservations become voice work, not dashboard chores that you need to do before you get in your car.

Responsibility shifts from the driver to the stack, and as many Tesla owners rely on FSD for travel, Grok Bot now handles the monotony of dinner reservations or appointments.

X changed how everyone gets paid, and this lawsuit shows why

X sued a Bitcoin account network over fake payouts as its creator pay model shifts

Elon Musk’s X has taken a Bitcoin-focused engagement ring to court, and the case doubles as a receipt for how differently the platform pays creators today. The company filed suit in the High Court of England and Wales against Vivek Kumar Sen and Zamyang Sherpa, alleging the pair ran six accounts, including @Vivek4real_, @Bitcoin_Teddy and @TrendingBitcoin, as one coordinated operation to fake the kind of engagement that used to translate directly into money.

According to the filing, first reported by Gizmodo, the accounts posted near identical “BREAKING” crypto headlines seconds apart, in one case 11 seconds, then had three more handles like, reply to and repost the material to manufacture what X called “a false appearance of genuine, human communication and interaction.” X says the scheme pulled in at least £207,384, about $278,000, and pegs its own investigation and remediation costs at another £75,000. The accounts were suspended August 18. X general counsel James Burnham announced the case on X last weekend, writing that the company “will act forcefully to protect our platform and the earnings of genuine creators.” Musk’s own reaction, posted shortly after, was three words: “Don’t mess with 𝕏.”

The timing lines up with a a recent update to how X pays its creators. The program these accounts allegedly gamed, Creator Revenue Sharing, launched in mid 2023 and paid out based on how much a post got engaged with. Originality was never part of the formula, which is exactly how the platform ended up flooded with recycled clips, copy pasted “BREAKING” posts and replies engineered purely to farm reactions from paying subscribers.

X tried patching the model more than once, including an April cut to aggregator payouts and a March regional weighting change that Musk personally paused hours after it was announced. X retired Creator Revenue Sharing for good on September 7 and opened its replacement, Original Content Rewards, the next day.

The new math is stricter. Payouts now come only from qualified impressions, meaning unique Home Timeline views from Premium subscribers where at least half the post is visible, and replies no longer count toward eligibility at all. Copied posts, reuploaded media and reposts without meaningful changes are explicitly excluded. Allegra Jacchia, senior product manager for Creators at SpaceXAI, which now runs X’s product and AI work following xAI’s acquisition of the platform, put it bluntly, saying the goal is to reward creators who bring original ideas and perspective, “not those who have become best at gaming the system.”

Read that way, the lawsuit isn’t really about six crypto accounts. It’s X putting a dollar figure on what the old incentive structure cost, then suing to collect it right as the new one goes live. For live updates on how the case and the new rewards program shake out, follow @Teslarati on X.
