SpaceX set to launch 40 satellites on fourth dedicated rideshare mission
SpaceX says a Falcon 9 rocket is on track to launch its fourth dedicated rideshare mission no earlier than (NET) 12:24 pm EDT (16:24 UTC) on Friday, April 1st.
Known as Transporter-4, SpaceX will launch the batch of 40 customer satellites out of its Cape Canaveral Space Force Station (CCSFS) LC-40 pad. Poor weather means that the company currently has a roughly 30% chance of favorable conditions on April 1st, improving to 50% on April 2nd and 80% on April 4th. Following the first NASA Space Launch System (SLS) rocket’s trip to a nearby launch pad, SpaceX also has to work around the agency’s plans to attempt an important wet dress rehearsal (WDR) test as early as April 3rd, preventing any launches that day.
SLS has already partially contributed to delays to Axiom-1 – the first all-private astronaut launch to the International Space Station – and could potentially disrupt Transporter-4 if weather or Falcon 9 fail to cooperate on Friday or Saturday.
Transporter-4’s payload of 40 satellites is the smallest number SpaceX has ever manifested on one of its dedicated rideshare missions. It’s unclear why so few satellites will be aboard, but one customer in particular likely explains why the company can launch such a small payload. That customer is Germany’s national space agency (DLR), which has manifested EnMAP – a hyperspectral Earth observation satellite – on Transporter-4. EnMAP itself is quite a bizarre case: the wildly overambitious smallsat was initially scheduled to launch as early as 2012 but has suffered a full decade of delays as endless issues arose. Painfully, those delays mean that EnMAP – a spacecraft largely designed before 2010 – is merely the latest in a long line of similarly capable satellites. Italy, for example, began work on an almost identically capable spacecraft – PRISMA – in 2008 and launched it in 2019 for ~$140 million.
According to one estimate, EnMAP’s cost has likely ballooned from ~$100 million to more than $330 million. In other words, it’s fairly reasonable to assume that SpaceX was able to charge DLR quite a bit more than Transporter-4’s other rideshare customers. SpaceX could have positioned it as a heavily discounted dedicated launch that just so happens to carry some secondary payloads – perhaps charging ‘just’ $15-30 million. EnMAP (950 kg or 2100 lb) is slightly heavier than the maximum weight SpaceX’s one-size-fits-all pricing allows for, but a customer with a similar 830 kilogram (1830 lb) spacecraft could launch it for as little as $4.6 million on a Transporter mission.
Of Transporter-4’s 40 payloads, at least 16 are using intermediaries like Spaceflight, Exolaunch, and D-Orbit, who then deal with SpaceX for the satellite owners. Excluding EnMAP, at least six other customers likely booked directly through SpaceX. Combined, total Transporter-4 revenue before EnMAP could be as low as ~$13 million. According to a SpaceX executive speaking in 2020, the total cost of a Falcon 9 launch with a recoverable, flight-proven booster is $28 million. Given that some executives have compared Transporter missions to public transit, it’s possible that SpaceX is willing to launch some rideshare missions even knowing they will lose money, but it’s hard to imagine it would burn $10-15 million (or more) instead of just delaying a few months to add more payloads.
Even though EnMAP is thus likely picking up all of financial slack, Transporter-4 is still a good demonstration of SpaceX’s flexibility – flexibility that current or prospective providers with much smaller rockets simply can’t match. With Falcon 9, SpaceX can just throw a 1-ton, $300 million spacecraft on top of a several-dozen-satellite rideshare mission and still recover both the booster and fairing without issue – all while charging its smaller customers a more or less unbeatable $1.1 million per 200-kilogram slot and $5500 for each additional kilogram.

SpaceX will begin streaming its first Transporter-4 launch attempt around 12:10 pm EDT (16:10 UTC).

The real reason Elon Musk wants every car connected to space
Elon Musk says all cars will eventually need Starlink to handle massive AI bandwidth demand.
Elon Musk is making the case that satellite internet, not fiber or cellular towers, will end up wired into every car on the road. In a string of posts on X, the SpaceX CEO wrote that all cars will have Starlink in the future and called satellite connectivity the only way to get super high bandwidth to billions of vehicles.
The posts started with Musk endorsing a Cloudflare forecast that traffic generated by autonomous AI agents will soon dwarf traffic generated by humans browsing the internet, a shift he described as not a close call at all. From there he narrowed the argument to infrastructure, writing that the only system that can support the insanely fast bandwidth growth needed by AI is Starlink, before extending the logic to cars specifically.
AI agentic Internet traffic will obviously VASTLY exceed human usage. Not a close call at all.

The timing lines up with Tesla’s own hardware decisions. On July 20, Tesla confirmed the Cybercab would ship with a Starlink V5 terminal built into its roof, the first time the company had put satellite hardware in a production vehicle. A day later, Tesla’s head of AI, Ashok Elluswamy, explained the connection wasn’t there for safety and that Cybercab’s driving stack runs entirely on onboard cameras and compute, while the satellite link exists for navigation, customer service, and fleet management instead. Musk followed with his own post about the feature, saying riders would be able to watch 4K streaming video during rides.
By July 22, Musk had already said Starlink would extend beyond Cybercab to Tesla’s full lineup. Sunday’s posts push that same logic outward again, this time framed as a requirement across the industry rather than a feature specific to Tesla, and tied directly to the bandwidth AI systems are expected to consume.
SpaceX’s newest Starmind will make earth data centers obsolete
The AI argument has been building on SpaceX’s side for months. The company has an FCC filing pending for a third generation Starlink constellation, and it has separately proposed Starmind, a constellation of up to a million satellites designed to run AI computation directly in orbit rather than just relay data. Musk has said he expects space to become the cheapest place to deploy AI compute within two to three years. Starlink and Starmind serve different jobs inside that vision, one moving data and the other processing it, but Sunday’s posts treat vehicles as one more category of hardware that will eventually need both.
None of this changes anything for Tesla owners today. Cars already on the road keep running on LTE and Wi-Fi, and Tesla hasn’t outlined a retrofit path for existing vehicles. The July 22 commitment applies to future production, not the fleet already delivered. What Musk added on Sunday is the reasoning: satellite connectivity isn’t a Cybercab novelty, it’s a bet that ground based networks won’t keep up with how much data cars, robots, and AI systems are about to generate.

The Boring Company’s newest tunnel vehicle runs on Tesla parts and no one is driving it
The Boring Company’s new tunnel vehicle runs on Tesla Model 3 batteries and drive units.
The Boring Company just introduced a new piece of hardware, and it runs on parts pulled straight from a Tesla showroom. Liner Truck 3, unveiled in a post from the tunneling company’s official X account, is an all electric vehicle built around Tesla Model 3 battery packs and drive units, purpose built to move concrete tunnel segments to the boring machine face without a single person underground.
Introducing Liner Truck 3 — our latest fully electric tunnel vehicle.

– Transports 22,000+ lb of concrete segments to the boring machine
– 28 miles of range
– 12 mph max operating speed

The job itself is unglamorous but critical. Each precast segment run weighs more than 22,000 pounds, roughly the load of a full cement mixer, and Liner Truck 3 hauls that weight repeatedly between the surface staging area and wherever the Prufrock machine happens to be cutting.
The Boring Company said Liner Truck 3 is piloted remotely out of its Global Operations Control Center in Texas, extending the Zero-People-In-Tunnel approach the company has spent years building toward. An earlier version of a ZPIT liner truck was already tested at the company’s Bastrop, Texas research tunnels, and a factory tour released last month showed an employee flying a fully loaded liner truck with a PlayStation controller. Liner Truck 3 looks like the production version of that same idea, cleaned up and pushed into daily use.
The timing lines up with a company digging in more places than it ever has before. The Boring Company now has multiple Prufrock machines active or arriving in Nashville, where Music City Loop construction has been accelerating since February, and its Vegas Loop network keeps adding tunnel mileage on a near monthly basis. Every one of those projects depends on getting concrete segments to the cutting face fast enough to keep the boring machine from idling, which is exactly the bottleneck Liner Truck 3 is designed to remove.
It also reinforces something Tesla owners have watched happen gradually across Musk’s companies: passenger car hardware finding a second life in heavy equipment. Model 3 drive units already move people through the Vegas Loop, and now the same components are hauling concrete underground in Nashville and wherever The Boring Company digs next. Whether that kind of component reuse extends further into TBC’s equipment lineup, or into other Musk owned industrial hardware, is the next thing worth watching.
SpaceX stock did the opposite of what most of Wall Street expected this week, when the day designed to be its most dangerous turned into a rally, and the rally kept going.
Thursday marked the first major lockup expiration since SpaceX’s June IPO, making roughly 911.5 million insider held shares eligible to trade for the first time, more than doubling the company’s public float. Analysts and short sellers had spent weeks bracing for a flood of selling, especially after the stock fell 13 percent following its first earnings report as a public company on Tuesday. Instead, shares rose 6.1 percent Thursday to close at $114.92, and by Friday they were trading near $129, up more than another 12 percent on the day.

The setup made the outcome notable. Short interest had climbed to roughly 34 percent of the float heading into earnings, among the highest of any large cap stock, with about 95 percent of available shares to borrow already on loan. CEO Elon Musk warned short sellers twice in the weeks before the lockup, writing on X that “the survival probability of firms who maintain a significant short position in SpaceX over time is very low,” then following up on the morning of earnings with “I try to warn them, but they just double down.”
When the newly unlocked shares hit the market and the selloff never showed up, some of that short position appears to have started unwinding. TipRanks reported that options activity shifted toward bullish strategies like put selling and risk reversals following the rally, with roughly $600 million in options premium trading Thursday alone. Retail buyers also stepped in during the earnings dip, according to Vanda Research.
The fundamentals behind the stock have not changed much in a week. SpaceX’s revenue nearly doubled year over year to $7.8 billion, with Starlink subscribers doubling to 12 million and the company’s AI segment growing 247 percent. What spooked investors on Tuesday was the spending side. Capital expenditures jumped to more than $18 billion for the quarter, up from $2.8 billion a year earlier, with AI investment alone rising from $749 million to $15.8 billion. Wall Street remains split on whether that spending is building infrastructure SpaceX needs or outrunning what the business can currently support, a debate Teslarati has tracked since shares first came under pressure.
None of that resolves the bigger question hanging over the stock. Thursday’s release was only the first of nine staggered lockup tranches, with roughly $800 billion worth of additional shares scheduled to become eligible through October, and Musk’s own stake stays locked until next June. If this week is any indication, the market is treating that supply as something it can absorb rather than something to fear, at least for now.
