SpaceX to launch one of its last old-gen Falcon 9s in upcoming launch

Published

on

One of SpaceX’s rapidly shrinking fleet of older Falcon 9 launch vehicles has rolled out to the company’s California launch pad ahead of an expendable launch and fairing recovery attempt scheduled for no earlier than Tuesday (NET) 12:47 pm PST/19:47 UTC May 22.

Although SpaceX may have inaugurated a new era of truly reusable rocketry with the debut of Falcon 9 Block 5 earlier this month, there are still a number of older Falcon 9 boosters (all flight-proven) awaiting their second and final flights. At the moment, a minimum of four cores remain, including the sooty Falcon 9 first stage captured earlier this evening by Teslarati photographer Pauline Acalin.

Foreshadowing its imminent watery demise with a lack of landing legs, this particular booster (B1043) previously launched the mysterious and controversial Zuma mission in January 2018, a classified payload claimed (sans convincing evidence) to have failed and reentered Earth’s atmosphere mere hours after reaching orbit. While it’s possible that the mission was a failure, at the moment unsteadily blamed on the failure of a Northrop Grumman-designed payload adapter and deployment mechanism, it’s far more probable that the apparently wildly-expensive satellite is still in orbit.

Checking the pulse of Earth’s gravity

Regardless, the same SpaceX rocket booster responsible for lifting Zuma and the Falcon 9 upper stage out of the atmosphere is now ready to launch a new payload at SLC-4E, a launch pad stationed in Vandenberg Air Force Base. B1043’s second orbit-destined payload is a compliment of seven satellites: five are of the Iridium NEXT variety and the remaining satellites make up a scientific mission and technology demonstrator known as GRACE-FO (FO for Follow-On).

Following in the footsteps of the original GRACE’s (Gravity Recovery and Climate Experiment) 15 year orbital tenure, GRACE-FO is effectively the same mission with significantly upgraded hardware – the biggest experimental component is actually an advanced laser interferometer designed to measure the distance between the two satellites (roughly equivalent to the distance between LA and San Diego) with the precision of a single micrometer (10-100x smaller than the width of a human hair). At that level of precision, the pair of satellites can detect minute changes in Earth’s gravity, to the extent that they can actually observe droughts, floods, and ice melt through the change in gravity caused by the movement of large (i.e. heavy) quantities of water. If the experimental laser ranging technology works as intended, it will be at least ten times more accurate than the microwave-ranging technology also installed on the follow-on satellites.

SpaceX’s rocket fleet makes way for Block 5

On the SpaceX side of things, Falcon 9 B1043 will be expended after dutifully completing the launch of Iridium-6/GRACE-FO, although the presence of grid fins on the rocket indicates that SpaceX will likely continue a regime of soft-landing recovery tests to optimize and flesh out the limits of Falcon 9’s capabilities. At first glance, the tradeoff of expending entire rocket boosters able to be (relatively inefficiently) refurbished for considerably more than two flights seems extreme and inadvisable. However, SpaceX is presumably ravenous for data on the survivable envelope of Falcon 9 performance – particularly reuse – in advance of the complete transition to the rocket’s Block 5 iteration, a significant upgrade likely to come hand in hand with a more pronounced aversion to expendable missions given each booster’s design lifespan of 10 to 100 missions. At that level of reusability, expending Falcon 9 Block 5s would truly become comparable with the absurdity of trashing an airliner after one or a handful of flights, an (in)famous talking point used by Elon Musk over his years of public SpaceX discussions.

Thus, if SpaceX can gather data that might enable future Falcon 9 Block 5 recoveries by expending much less valuable Block 3 and 4 boosters, the payoff would be irresistible once examined with a long-term outlook. In the sense that Block 5 may be capable of magnitudes more flights with considerably cheaper refurbishment, the literal elemental value of the hardware – in the likely event that Block 5 production is more capital-intensive than Block 3/4 – is more or less irrelevant for an aversion to expending Block 5 boosters.

Rather, what is lost alongside an expendable Block 5 mission is instead the comparatively vast amount of revenue locked within dozens of additional highly-profitable launches each expended booster could have supported. From that perspective, expending Block 3s and 4s to gather data might be accurately compared to destroying single-pilot Cessnas to improve the utility of a 747 airliner.

After B1043 is expended, only three obvious flightworthy cores will remain outside of the gradually growing Falcon 9 Block 5 fleet (just two boosters, currently). In order of anticipated launch, these three missions are SES-12 (NET May 31), CRS-15 (NET June 28), and the Crew Dragon in-flight abort test (NET Q4 2018). Barring the unexpected refurbishment of an older flight-proven core for a third mission, these final three missions will bring to a close the inherently temporary era of partially-reusable SpaceX rockets – in the words of Elon Musk, Block 5 would thus signify that SpaceX has moved from “the dog that caught the bus” to, perhaps, the dog that caught the bus and then learned how to drive and maintain it. Somewhere in the middle of those final throes of old-guard Falcons will be an ever-increasing cadence of Block 5 launches and re-launches, likely including the first manifest-necessitated reuse of a Block 5 booster sometime this summer.

Meanwhile, despite the sealed fate of the rocket’s booster, tomorrow’s launch will debut fairing-catcher Mr Steven’s new and improved net. With the introduction of an upgraded net and what can only be described as back-to-back days of relentless ocean-going practice over the last two weeks, it’s entirely possible that Iridium-6/GRACE-FO will be able to lay claim to the first successful catch of a payload fairing following an orbital rocket launch. Fingers crossed.

Follow the mission live on SpaceX’s webcast at 12:30 pm PST on Tuesday, May 22, and make sure to check back at Teslarati over the course of the week as photographer Pauline Acalin covers Mr Steven’s return to Port of San Pedro.

SpaceX just combined Grok, Cursor, and X into one mega plan

SpaceXSI merges Grok, Cursor, and X Premium into one plan, raising questions for Tesla owners.

Published

By

SpaceX Super Intelligence has rolled out The X Subscription, a single plan that combines Grok, Grok Bot, Cursor, and X Premium.

There are five levels, including a free plan that includes daily Grok access and a starter allowance for Cursor’s coding agents. Plus is $8 per month, Premium is $30, Super is $100, and Ultra is $200. Usage scales as you move up, with Premium offering four times the Plus allowance, Super 15 times, and Ultra 50 times. Annual billing brings the prices down a bit further, with Premium at $300 per year.

The $30 Premium tier is where SpaceXSI says it packs the benefits of SuperGrok, Cursor Pro, and X Premium+, which previously added up to $90 per month. Grok Bot, the agent that handles tasks like ordering food or managing a calendar, is included from Premium upward but not on Plus. Paid plans share one weekly usage pool across Grok and Cursor, and each plan includes at least twice the coding usage of the comparable Cursor plan. Third party models in Cursor remain available on Premium and above, but they are billed separately at API list prices.

That last detail matters because of what has happened around Cursor this year. SpaceX exercised its option to buy the company for $60 billion in June, and the deal closed in August. Weeks later, OpenAI said it will cut Cursor’s access to its models on November 12. Bundling Cursor with Grok usage gives SpaceXSI a reason to steer developers toward its own models.

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

For Tesla owners, the connection is Grok Bot. Tesla brought it into its vehicles last month, and at that point access inside the car was limited to SuperGrok Heavy subscribers. Grok Bot is now enabled across every Cybercab and the rest of the Model Y Robotaxi fleet. Neither SpaceXSI nor Tesla has said how the new plans change inside the car access for owners, or whether a $30 Premium subscription now covers Grok Bot in a personal Tesla. That is the question owners will want answered first.

The company is also changing its name along the way. The rollout follows the rebrand Musk announced on October 4, when he said SpaceXAI would become SpaceXSI, and the plan page now carries that branding.

The X Subscription is available to new customers starting now, and SpaceXSI says it will reach everyone globally over the next few days. Existing SuperGrok, Cursor, and X Premium subscribers do not have to switch. The option to move will appear gradually in billing settings, with a prorated refund for the unused time on the old plan. Switching is permanent once the accounts are unified, and old plans are closed to new sign ups.

Taiwan power firm bets big on Tesla Megapacks as AI data center thirst grows

Taiwan’s Apollo Power orders 260 Tesla Megapacks, betting AI data centers will need more electricity.

A Taiwanese power company has ordered 260 Tesla Megapack 2XL units, roughly 1GWh of storage, betting that electricity rather than chips will decide how fast AI data centers come online. Apollo Power signed the contract with Tesla’s Taiwan energy arm on October 8, according to the company’s filing with the Taiwan stock exchange.

The filing says the units are meant for behind the meter storage and resilient grid projects, with delivery in batches from the end of 2027 and sites operating in 2028. Apollo and Tesla did not disclose a price, citing a confidentiality agreement. Apollo plans to pay for the equipment through a cash capital increase and bank financing, and it noted the purchase is not revenue and does not mean it holds firm orders from its partners.

Biggo reported that only about 33 units are under signed customer contracts, with roughly 150 more in negotiation. The same report put total project investment near NT$130 billion, but that figure includes installation work, with the equipment itself making up about 40 to 50 percent. In other words, a large share of this order is Apollo reserving supply ahead of demand. Apollo’s chairman told local media global large storage supply is tight, which is why the company locked in the units early, according to Yahoo Taiwan Finance.

Apollo also launched an AI data center and grid resilience alliance with Phison, Gigabyte and Shihlin Electric. The pitch rests on a pilot at Phison’s Zhunan plant, where Apollo and Tesla Energy Taiwan installed grid forming Megapack 2XLs in June. Tesla Energy Taiwan general manager Sun Hsiao-Han said the project went from demo to 1GWh in four months, and that Tesla Energy has deployed more than 50GWh worldwide.

Taiwan’s cabinet has approved amendments that would require large energy users to install their own generation and storage, which gives enterprise storage a regulatory tailwind.

The deal fits a pattern Teslarati has tracked. Tesla’s Megablock targets 1GWh commissioned in 20 business days, a pitch aimed squarely at fast moving data center builds. Megapacks already back xAI’s Colossus in Memphis and a 400MW AI campus in Brazil. Sun Media adds that Megapack 2XL was named among the first products in Nvidia’s DSX Ready qualification for battery storage in AI factories.

Deliveries are more than a year away, so the real test is how much of that 260 unit order turns into signed customer contracts.

Tesla Cybercab and Robotaxi’s real advantage won’t be the ride service

Published

For a century, the car has asked the same thing of its owner, which is basically to pay attention. Even the best ride-hailing app like Uber or Lyft only moved the problem into someone else’s hands. You stopped driving, but you still sat in a stranger’s car, while half listening, and wondering whether to take a phone call in the car without being rude. The Cybercab has no wheel, no pedals and no driver. With Grok @bot now live inside it, it becomes something else entirely, and I think that matters more than the fleet count that everyone is tracking.

Grok @bot is an agent, not a voice assistant. A rider signs in once, and from then on can say what they need and watch it happen. Order dinner from a favorite restaurant. Fill the grocery cart. Move money, answer email, adjust a calendar, push a work project forward. Tesla engineer Yun-Ta Tsai confirmed it is enabled across every Cybercab and the rest of the Model Y fleet, and Tesla’s own pitch is that Full Self-Driving handles the commute while Grok handles the errands.

Think about what that does to a thirty minute ride. Uber sells you a trip, while Waymo sells you the same trip in a more private setting. Tesla is selling the thirty minutes themselves, returned to you with an assistant attached. Errands that used to eat a Saturday get done between pickup and drop off. The ride stops being dead time between two places and becomes a place of its own.

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

Best of all, your Bots follow you into any Cybercab, and presumably your own Tesla, then logs you out automatically when you step out. Anyone can bolt a chatbot onto a screen, but much harder to own the vehicle, the autonomy stack and the assistant at once. It also quietly ties SpaceX’s Super Intelligence business to Tesla’s fleet, after Tesla converted its xAI stake into SpaceX equity. The relationship between those two companies is getting harder to describe as separate.

This is also where the hard questions start, because an agent that can spend your money in a vehicle other people also ride in needs some answers. How does it handle a voice it shouldn’t trust? What gets recorded, who can see it, and for how long? What happens when a rider leaves halfway through a task?

If Tesla gets those answers right, the scoreboard changes. We have been counting Cybercabs and wait times. The more telling number may be what riders accomplish per trip. That is data almost no one else will ever have, and it is the real reason to watch Grok @bot.
