SpaceX says Crew Dragon’s upgraded “Mk3” parachutes are almost ready to safely return astronauts to Earth and need to pass just a few more consecutive tests before NASA will have the data it needs to qualify them.

Although SpaceX originally hoped to pursue a program of propulsive landing for Crew Dragon and Cargo Dragon space capsules, that effort was canceled to avoid the major cost increases and delays NASA’s qualification certification requirements would have triggered. Already designed with parachutes as a backup, SpaceX quickly pivoted and redesigned those parachutes as the primary (if not sole) method of gently landing astronauts back on Earth.

That decision was likely made in late 2016 or early 2017 and CEO Elon Musk announced the program’s cancellation – as well as plans for “Red Dragon” Mars landings – in July 2017. For the next 18 months, SpaceX worked with suppliers and NASA to design and test a parachute system up to the space agency’s extremely rigid standards. Coincidentally, Cargo Dragon suffered a significant (but survivable) parachute failure the same year when one of its three main chutes failed to deploy before splashdown. Additionally, Crew Dragon’s first “Mk1” parachutes suffered their own failures during testing.

A Mk2 variant was designed and built to account for Mk1’s issues, but it too suffered failures during field tests, particularly struggling to make it through tests simulating the failure of one Dragon’s main parachutes. As a result, NASA further required SpaceX to add a fourth parachute, requiring a whole new round of tests and experimentation due to the significantly different dynamics it introduced. Mk2 testing continued into 2019 but SpaceX quickly switched gears and worked with its supplier to design an even more upgraded “Mk3” parachute, building off of a cutting-edge program to model parachute deployment more accurately than ever before.

Over the course of 2019, SpaceX began to extensively test Mk3 parachutes with a variety of drop tests. Unfortunately, even Mk3 suffered a failure or two at first, leading SpaceX and its supplier to refine the design even further.

“[In October and November,] SpaceX says it successfully completed thirteen consecutive tests of Crew Dragon’s new Mk3 parachutes in less than two weeks. That essentially blew [NASA administrator Jim] Bridenstine’s expectations out of the water, as SpaceX surpassed his predicted 10 tests and did so barely three weeks into the tentative 12-week window he set. SpaceX now has plenty of time to either continue testing Crew Dragon’s parachutes or refocus its efforts on other equally important qualification challenges.

Prior to those thirteen consecutive successes, SpaceX suffered two failures during single-parachute Mk3 testing. The first two development tests of the Mk 3 design used loads much higher than the parachutes would ever see in operation in an effort to better understand overall design margins and system performance. After a period of rapid iteration with parachute provider Airborne Systems, the faults responsible for those two stress-test failures were resolved and subsequent drop tests confirmed that Mk3’s suspension lines – the numerous lines connecting the parachute to Crew Dragon – are far stronger than those on Mk2.”

In the latest chapter of the Crew Dragon parachute saga, on December 4th, SpaceX tweeted that the spacecraft’s upgraded Mk3 chutes recently completed their seventh successful “system test”. On November 3rd, CEO Elon Musk tweeted that one such multi-chute test had already been completed but said SpaceX wanted to successfully complete ten such consecutive tests before it would feel fully confident in the upgraded parachutes.

If the seven tests SpaceX is now describing are part of the same planned series that kicked off in early November, then those seven were likely consecutive successes and leave just three more tests (give or take) to go. Additional testing may well be required by SpaceX, NASA, or both parties, but if Mk3 continues to perform as well as it has over the last two months, Crew Dragon’s recovery systems ought to be well on their way to NASA certification. Once NASA gives the go-ahead on Crew Dragon’s parachutes (and every other facet of the spacecraft), SpaceX can proceed with its Demo-2 mission, set to be SpaceX’s inaugural astronaut launch and likely to mark the first time the US has launched its own astronauts in nearly nine years.

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.

Published

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

Published

Credit: Grok

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

Published

By

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.
