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 extremely young age of the full-scale engine test program, known (publicly) to have only completed a couple dozen seconds of hot-fire testing in February.

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.

Musk’s Tesla and SpaceX decline after Democratic Midterm sweep

Published

on

Credit: Grok

Tesla and SpaceX shares fell on Wednesday after Democrats swept both chambers of Congress. The decline stood out as broader market securities recovered and turned positive, while both of Musk’s publicly traded companies lagged.

CEO Elon Musk already joked about the unsuccessful campaigning for the Republicans, but now the new party will make pretty drastic changes to how it handles Tesla and SpaceX, and those companies will adjust their outlook.

Elon Musk hilariously comments on Midterm election results

Let’s take a deeper look.

Tesla ($TSLA)

Tesla shares traded lower during the regular session after Democrats secured both the House and Senate. The stock was down 2.32 percent at around 1:45 p.m. on the East Coast, trading at around $389.30.

The pressure is tied to more than the raw scale of Musk’s political spending, estimated at $450–474 million this cycle with roughly $224 million directed at Texas. In that state, Tesla now faces a Democratic governor and a Democratic senator after Gina Hinojosa unseated Greg Abbott and James Talarico defeated Ken Paxton.

The Austin Gigafactory, Robotaxi pilot programs in multiple Texas cities, and any related AI compute expansion sit under a new state executive who campaigned against certain corporate subsidies and floated a moratorium on new data-center construction.

Federally, Democratic control of key committees opens the door to deeper examination of Tesla’s autonomous-driving safety record, federal energy-storage and manufacturing incentives, and the national-security implications of any combination with SpaceX.

Investors are also weighing whether the company’s historically close alignment with the prior Republican leadership will invite slower permitting, additional hearings, or tighter rules on Full Self-Driving deployment.

For Tesla, the political shift adds near-term friction around state permitting and federal regulatory approvals for autonomy and energy storage. A potential merger with SpaceX may face slower review even if it proceeds.

Core growth drivers such as vehicle deliveries, energy deployments, and robotaxi rollout remain intact, yet the stock now carries a higher political-risk premium that could weigh on valuation until the company demonstrates workable relationships with the new Texas leadership and congressional majorities.

SpaceX ($SPCX)

SpaceX shares also declined in live trading on November 4 following the Democratic midterm sweep. The stock traded at $134.97, down 4.49 percent. The drop occurred even as broader indexes stabilized, highlighting a company-specific reaction to the election outcome.

Musk’s large contributions, concentrated in Texas races that both companies lost, place SpaceX’s Starbase launch facility and headquarters under a new Democratic governor.

At the federal level, Democratic control of Congress enables greater scrutiny of NASA, the Department of Defense, and other contracts that support a meaningful share of revenue, along with reviews of Starlink national-security uses and any Tesla merger. Analysts have noted that empowered committees can hold hearings and request documents on these relationships.

For SpaceX, the results raise the risk of delayed contract awards, higher compliance costs, and tighter constraints on AI and satellite infrastructure expansion, particularly in Texas where a data-center moratorium has been discussed.

A merger with Tesla could encounter political friction that slows integration of launch, connectivity, and autonomy capabilities.

While Starlink growth and launch cadence continue as primary drivers, the company faces a more contested path for federal funding and state-level operations, requiring management to rebuild ties with the new congressional majorities and Texas leadership to limit the overhang.

SpaceX moves to challenge AT&T, Verizon with Qualcomm-powered 5G

Published

SpaceX has selected Qualcomm Technologies to supply core infrastructure for Starlink Mobile’s planned nationwide terrestrial 5G network in the United States.

Announced on November 4, the multi-year agreement covers radios, baseband units, and commercial-grade Layer 1 software based on Qualcomm’s Dragonwing Cellular Infrastructure platforms, specifically the QRU100 and QDU100:

These will power Massive MIMO radio units featuring 64 transmit and 64 receive paths (64T64R), designed to boost coverage, capacity, and spectral efficiency at scale. Qualcomm has described the pact as its largest 5G deal to date, with deployment across tens of thousands of U.S. cell sites scheduled to begin in 2027.

The terrestrial build-out is meant to complement, not replace, Starlink’s satellite direct-to-cell capabilities. SpaceX has assembled substantial spectrum holdings for this purpose: roughly 65 MHz of mid-band frequencies acquired from EchoStar (including AWS-4 and related bands) and up to 14 MHz of low-band 800 MHz spectrum from Grain Management.

The low-band airwaves improve indoor penetration and range, while mid-band supports higher capacity. SpaceX executives, including President Gwynne Shotwell, have outlined a hybrid architecture in which satellites eliminate outdoor dead zones and terrestrial nodes add capacity where demand is highest.

Earlier comments suggested small cells or femtocells potentially co-located with existing Starlink user terminals on roofs, though later filings also reference more conventional antennas on towers and structures.

The big picture is SpaceX’s bid to become a full-fledged U.S. mobile carrier rather than a satellite partner or dead-zone filler. AT&T, Verizon, and T-Mobile together generate hundreds of billions in annual wireless revenue; Shotwell has said SpaceX expects to win customers by offering superior coverage, including during disasters, through seamless satellite-terrestrial handoff.

Verizon, AT&T and T-Mobile are trying to shut Starlink out before FCC vote

Starlink already represents a major share of SpaceX’s revenue and profit following the company’s 2026 IPO. By vertically integrating spectrum, satellite manufacturing, launch capacity, and now ground radio equipment, SpaceX aims to control more of the connectivity stack.

Qualcomm’s involvement also positions the network for future evolution toward AI-native 6G infrastructure, with energy-efficient processing that could improve deployment economics.

Challenges remain: spectrum depth still lags the Big Three, capital costs for tens of thousands of sites will be substantial, and regulatory approvals continue, but the Qualcomm deal marks a concrete step from spectrum accumulation toward operational network build-out.

In short, the partnership accelerates Starlink Mobile’s shift from orbital broadband specialist to hybrid mobile competitor, testing whether a space-based company can reshape terrestrial wireless economics and coverage in the world’s largest market.

Elon Musk’s Grok Bot is picking up the phone now, and the first calls are wild

Elon Musk wants Grok Bot users making phone calls, and one Comcast call saved $500.

Published

Elon Musk is pushing Grok Bot users toward a feature that, until this week, few of them could actually use. “Try asking Grok @Bot to make calls!” Musk wrote on X Tuesday afternoon, quoting a demo from Sawyer Merritt that included audio from a live call.

Musk first announced calling on October 25, writing that the agent could “call someone or a business for you, make a request on your behalf, take notes on the response and send you a note summarizing the conversation.” There were no release notes at the time, and the feature only appeared in preview builds. That changed on Tuesday, when creator Peter Yang said all Grok Bot users should now be able to call US businesses. Musk reposted his demo.

Yang’s call shows how far the feature goes. In his video, his bot dialed Comcast, worked through the phone menu, deflected small talk about the weather by saying it does not “have eyes on the sky,” turned down three upsells and used a cheaper fiber offer from competitor Sonic as leverage. His bill dropped from $84 to $45 per month on a faster plan, a savings of nearly $500 a year. The call ran about 25 minutes, and the bot paused to get Yang’s approval before accepting the final terms.

Merritt described what the user sees: a live transcript runs during the call, and when the business asks for something the bot does not know, an answer box pops up in the chat. The user types a reply and Grok relays it to the person on the line. Other users posted results Tuesday, including a $100 gift card recovered from Verizon Fios after a 51 minute call and a same day pediatric appointment, which Musk also shared. Not every call worked. One user said a rep refused to cancel a subscription once it was clear an AI was on the phone.

The Grok Bot terms require every call to identify itself as a virtual assistant calling on the user’s behalf and warn that calls may be recorded. Marketing, mass calling and impersonation are prohibited, and calling currently works only with US numbers.

The timing stands out. Days ago, users began hitting their weekly limits early, and Musk said the cost of serving Grok Bot was “unsustainably high relative to revenue,” as Teslarati reported. A call that spends most of its 25 or 50 minutes on hold is the kind of long running task that eats into usage, and SpaceXSI has not said how calls count against the weekly pool. Grok Bot is included from the $30 Premium tier of The X Subscription upward.

For Tesla owners, the agent has been in their cars since September 22 and is enabled across every Cybercab and Model Y Robotaxi. Musk has already pitched it for phone chores like scrubbing your number from spam call lists. Neither Tesla nor SpaceXSI has confirmed whether a bot can place one of these calls on request from inside the vehicle.
