SpaceX’s Starship hopper steps towards first hop with several cautious tests
SpaceX’s team of South Texas engineers and technicians have dived into a program of critical pre-hop tests of the first assembled Starship prototype, a partial-fidelity vehicle – known as (Star)Hopper – meant to soon perform low-altitude, low-velocity hop tests powered by Raptor.
Despite a lack of official information is known and SpaceX’s general silence – even to local residents – about Starhopper’s testing, some barebones insight can be derived from what has and hasn’t been done or seen over the past seven days of testing, as well as five apparent wet dress rehearsals (WDRs). To verify the operational integrity of Starhopper and iron out best practices for what is effectively a one-off mobile test stand for Raptor, these WDRs (and one more active test) have seen the unusual prototype filled with some amount of liquid oxygen and methane propellant, taken to flight (hop?) pressures, and generally monitored closely to gather valuable telemetry and judge Starhopper’s condition and hop-readiness. Aside from Hopper, these tests also serve as a shakedown for complex pad and support facilities sprung up from a dirt pile in barely three months.
Fueling the beast
Starhopper’s five (ish) wet dress rehearsal tests have demonstrated an intriguing level of caution relative to the last few months of BFR program development. Depending on how much propellant SpaceX has been filled the vehicle with and how much of that propellant they are able to recycle after each attempt, each dress rehearsal could cost upwards of six figures (USD), while also putting the unusual steel structure through multiple stress cycles.
No official info has been provided beyond a brief indication that SpaceX means to static-fire Starhopper before transitioning to tethered hops, meaning that it’s quite difficult to determine what exactly the testing plan and schedule are. In other words, these ~5 WDR tests could have been the plan all along, or each test could be producing data that has lead launch engineers to scrub Raptor ignition attempts nominally planned at the end of each rehearsal. For an entirely new and unfamiliar design like Starhopper, it seems likely that at least one or two WDRs were planned before any attempt to static fire the hopper’s lone Raptor, although it could also be the case that – much like most SpaceX static fire attempts – the WDR was simply built in as a precursor to ignition, barring off-nominal telemetry.
The third and most visibly active test yet (above) occurred on March 25th and saw Starhopper briefly vent a cloud of gas from Raptor, with some viewers guessing that a Raptor preburner (partial ignition) test had been observed. It’s unclear whether this Raptor (SN02, the second produced) completed acceptance testing in McGregor, Texas on the way from California to Boca Chica. If not, then the caution on display in these WDR tests (i.e. no visible Raptor ignitions) could also be a side-effect of
The fidelity of Starhopper relative to its orbit-facing successors is also unclear. If the prototype’s structures, avionics, and plumbing are actually more indicative of the finished product than they appear, it’s possible that SpaceX tendency towards accepting the destruction of test hardware is in a bit more of a cautious state than usual, with a total loss of vehicle amounting to a significant technical setback and schedule delay. Based on the vehicle’s appearance and the apparent decision to entirely set aside the idea of installing a new fairing on Starhopper, it seems far more plausible that the prototype is more of a glorified mobile test stand for Raptor engines and Starship avionics (software) than anything else.
If Starhopper really can’t function as something more than a marginally mobile test stand for Raptor(s), then the value of actually hopping the craft could be quite minimal, perhaps offering useful data on Raptor’s control loop and behavior during flight operations. Still, CEO Elon Musk has stated several times that SpaceX has gotten good enough at the actual task of landing rockets vertically that it’s effectively a known quantity for Raptor and BFR, whereas the exotic atmospheric operations planned for Starship are the main uncertainty for successful recoveries.
Simultaneously, SpaceX is building the first orbital-class Starship prototype just a few thousand feet away from Starhopper’s new roost, utilizing stainless steel sheets almost three times thinner than the quarter-inch-thick steel the first prototype was built out of. It’s likely that Starhopper’s career will thus end up being rather short, given that the completion of the first near-final Starship would further minimize the low-fidelity hopper’s utility. If it’s actually meant to reach orbit, the newest Starship prototype will require the tripod fins and canard wings shown in SpaceX’s latest renders in order to safely land for future test flights, while Starhopper appears to be far too heavy and simplistic to warrant the expensive and time-consuming task of outfitting it with aerodynamic control surfaces and a new nose cone capable of surviving the associated forces.
While additional testing may be done on Friday, March 29th, it appears that the next attempts for the first static fire (and hop tests) will begin next week (likely Monday) – SpaceX is unlikely to test on weekends due to the potential disruption it could cause for beach-going locals.

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.
SpaceX shorts get warned by Musk ally, echoing Tesla’s early struggles
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.

Tesla’s mysterious Robovan makes a sneak peek with Optimus in Terafab video
Elon Musk shared a new Terafab video showing Optimus, Robovans, and a stunningly futuristic campus.
Elon Musk posted a new video of Terafab on X Thursday morning, and the most eye-catching details in it were not the building itself, but two products still awaiting production: Optimus and the Robovan.
The concept render, credited to SpaceX, shows Optimus robots working the grounds of the roughly 2.5-mile-long facility planned for the Gibbons Creek site in Grimes County, while a Robovan glides along an elevated roadway cutting through the building itself, sharing the frame with a Tesla Semi and a Cybercab.
Robovan is the boxy, driverless people and cargo mover Musk unveiled alongside Cybercab at Tesla’s “We, Robot” event in October 2024. He pitched it as a way to move up to 20 passengers at once, or handle freight instead, at a target cost he claimed could fall under a dollar a mile, with no steering wheel or pedals, the same layout as Cybercab. Nearly two years later, Robovan still has no confirmed production timeline and has not shown up in any factory footage, which makes Thursday’s render one of the only recent looks at the vehicle in any form.

Optimus has moved further along. Tesla began converting Fremont’s old Model S and Model X assembly line into a Gen 3 Optimus production line earlier this year, and Musk visited the site on July 1 to mark the changeover. A second, larger Optimus plant is under construction at Giga Texas, targeting volume production in summer 2027 and eventual capacity of 10 million units a year. Tesla AI lead Ashok Elluswamy said this month the robot has “big shoes to fill” in replacing the S and X line, while Musk has repeatedly called Optimus the company’s biggest product of any kind, with a long-term price he has pegged between $20,000 and $30,000.

“Terafab Texas will be the largest and most valuable building on Earth by far,” Musk wrote alongside the clip. “And it will be stunningly beautiful.”
One quote post summed up the reaction: “Futuristic scene with RoboVan + Cybercab + Tesla Semi + Optimus.”
Beyond the vehicles, the architecture wrapped around them stands out too. The building’s facade is canted at sharp angles, with illuminated horizontal bands running through what appears to be a multi level interior visible from outside. Below the elevated roadway, pedestrians walk along a plaza next to a reflecting pool, and the skyline behind the campus is dotted with angular spires that read more like sculpture than infrastructure, a departure from the strictly utilitarian look of Gigafactory Texas or Starbase.
The timing tracks with what Terafab representative Riley Trennell told Grimes County residents on Wednesday, when he said renderings of the facility would be released “within days.” Musk’s post followed less than 24 hours later, and Texas Governor Greg Abbott’s office sent out its own release Thursday confirming the project. As Teslarati reported this morning, Terafab’s tax abatement agreements with Grimes County are now signed and active, and SpaceX has sent the county its first $10 million payment under that deal. The dollar figure tied to this phase of construction, per Reuters, is $16.8 billion, one of the first hard capital expenditure numbers attached to Terafab since Musk unveiled the joint Tesla-SpaceX-xAI venture in March.Reaction on X ranged from enthusiastic to skeptical. “God Bless Texas! Everything is bigger and better in Texas!” one reply read. Another was more measured: “Terafab in a decade…..”
Whether the finished building matches the render is a separate question from whether Musk wanted people talking about the render itself. Less than a day after posting, the video had already crossed 5.5 million views.

Space finally faced the people living next to its next Terafab mega-project
SpaceX confirmed Terafab’s Grimes County site is locked in, with construction starting within months.
SpaceX and Terafab representatives sat across from Grimes County residents for the first time on Wednesday, telling a packed Commissioners Court room that the $55 billion chip manufacturing project is now a done deal at the Gibbons Creek Reservoir site.
The meeting followed a $10 million check SpaceX sent the county earlier this week, satisfying a payment deadline built into the tax abatement agreement both sides signed in June. Elon Musk shared a post on X confirming the payment, and County Judge Joe Fauth told the San Antonio Express-News his office deposited the check after it beat its deadline.
Wednesday’s session, first reported by KBTX, moved the project from paperwork to construction. Terafab representative Riley Trennell told residents the JETI tax break agreements with Iola ISD and Anderson-Shiro CISD are signed and active, and that civil work and foundation prep are starting almost immediately. Renderings of the facility could be released within days, he said, with construction beginning within months.

Elon Musk launches TERAFAB: The $25B Tesla-SpaceXAI chip factory that will rewire the AI industry
Musk first announced Terafab in March as a joint venture between Tesla, SpaceX and xAI aimed at producing over a terawatt of AI compute annually, an amount that dwarfs the roughly 20 gigawatts the entire global chip industry produces today. Intel joined as a manufacturing partner in April. Musk has said the project needed its own day in the spotlight rather than being squeezed into an earnings call, and for months the Grimes County site remained unconfirmed even as reporting pointed there.
SpaceX attorney Buck Brannon used Wednesday’s meeting to note that the company’s abatement is roughly 78 percent, not the 100 percent some earlier reports suggested. In exchange, SpaceX will pay Grimes County a fixed $20 million a year for 35 years, a total of $710 million, which Brannon said exceeds the $14 million Tesla paid Travis County in 2025.
SpaceX also addressed environmental concerns that have followed the project since Musk’s Terafab partnership with Intel was announced. Representatives said Terafab will not raise electric bills for other ratepayers, will not deplete local water supplies and will not draw down the Navasota River. SpaceX confirmed it owns the Navasota River pumping station, which it plans to use to divert stormwater into the Gibbons Creek Reservoir, and said it will build its own natural gas plants to power the facility rather than pulling from the ERCOT grid.
Grimes County commissioners also approved an addendum letting county employees use ten approved AI chatbots for work, including Grok.
