According to SpaceX CEO Elon Musk, the company’s next major Starhopper flight test is still awaiting FAA approval due to a need for more hazard analysis, presumably required because Starhopper will be traveling much higher than before.

On August 9th, SpaceX completed a routine wet dress rehearsal (WDR) with Starhopper, loading the vehicle with propellant and fluids and replicating a launch countdown up to the point of Raptor ignition. Starhopper remains untethered in a sign that SpaceX doesn’t have plans for a static fire test before the low-fidelity rocket prototype’s next flight milestone. Originally scheduled for August 12th, that milestone – a 200m (650 ft) hop test – has been indefinitely delayed as SpaceX awaits an updated permit from the Federal Aviation Administration (FAA).

The oddity of the apparent difficulty SpaceX is having with the FAA’s experimental permit process is deepened by the fact that Starhopper is already permitted by the FAA and demonstrated its first successful flight just a few weeks ago, on July 25th. On top of the fact that the local Boca Chica and Brownsville, Texas airspace tends to be extremely quiet, it’s unclear what exactly is holding up SpaceX, the FAA, or both in what should otherwise be a relatively streamlined process.

A few weeks ago, after one false start on July 24th, Starhopper performed its first untethered flight ever on July 25th, successfully demonstrating its integrated steel propellant tanks, avionics, software, and Raptor propulsion over the course of 20 or so seconds of flight. Starhopper’s inaugural flight was delayed at least several weeks by a major bug with SpaceX’s next-gen Raptor engine, described by Elon Musk as a problem with a certain frequency of vibration (i.e. mechanical resonance).

According to Musk, said resonance failure mode was effectively solved with unspecified modifications made to the sixth Raptor engine produce (Raptor SN06). That engine became the first to successfully pass SpaceX’s regime of pre-hop static fires in McGregor, Texas around July 10th and was shipped south to Boca Chica and installed on Starhopper scarcely 24 hours later.

Assuming those vibration issues have been completely quashed, Musk has also stated that SpaceX is aiming to produce as many as two Raptor engines per day by the end of 2019. It’s believed that all engines preceding SN06 (SN01-05) were either damaged or destroyed during testing, be that a result of intentional testing-to-destruction or anomalous behavior during certain test regimes. It should be noted that full-scale Raptor is still undoubtedly in development and hardware failure during developmental testing is more predictable and valuable than it might seem. As long as the program can handle it, ‘hardware-rich’ development (i.e. moving fast and breaking things) can be equally – if not more – valuable than an extremely cautious get-it-right-the-first-time approach.

Regardless, once SpaceX’s propulsion engineering team is confident that the more major bugs that plagued early Raptor engines have been alleviated, they will likely give the go-ahead for the engine manufacturing team to begin ramping production rates. Musk believes that SpaceX could be ready for the first test flights of either or both of the company’s orbital Mk1 and Mk1 Starship prototypes as early as mid-September, milestones that will eventually require three sea-level Raptor engines and up to three vacuum Raptor engines per rocket.

Meanwhile, although SpaceX has yet to begin assembling the first Super Heavy booster(s), said boosters will require dozens of Raptor engines each for their first flights. Musk says that SpaceX will start out with something like 20 Raptor engines per booster to minimize losses and disruption in the event of a catastrophic failure, eventually expanding to as many as 35 engines per booster as confidence grows.

For now, Starhopper’s next flight test was scheduled from August 16th through the 18th but has since been tentatively rescheduled to Aug. 19-21. Starhopper will remain grounded until the FAA is satisfied with SpaceX’s updated hazard analyses for the rocket’s 200m flight test.

Elon Musk breaks his silence on the Starlink impact to Ukraine drones

Musk says the US military and president set Starshield limits, not SpaceX, amid Ukraine complaints.

Elon Musk says the speed limit cutting out Ukraine’s military Starlink terminals is not SpaceX’s decision. In a post on X Wednesday, Musk wrote that “Starshield systems are owned and controlled by the US government. Any limits on speed or usage are decided by the US military and ultimately POTUS.” He added that Starlink is a commercial service limited to civilian or defensive activities and “cannot be used for offensive military action, as doing so would be inappropriate for a commercial company.”

He was replying to Mykhailo Fedorov, Ukraine’s former defense minister, who had thanked Musk for restoring connectivity at speeds up to 160 km/h and said removing the Starshield limit entirely is “now critical for Ukraine’s defense.”

The complaint started Tuesday night, when Ukrainian officials said military terminals began losing service above roughly 100 mph. Presidential adviser Serhiy Beskrestnov said the defense forces got no warning and several missions were disrupted, as Teslarati reported earlier Wednesday. The 7th Rapid Reaction Corps told Reuters connections dropped for 10 to 20 seconds at speeds well below the limit, which made drones harder to control. Poland’s foreign minister, Radoslaw Sikorski, asked Musk on X whether he is “playing politics with your products again.”

That is why the Starlink and Starshield distinction matters. SpaceX introduced Starshield in 2022 as the government version of Starlink, with an initial focus on Earth observation, communications and hosted payloads. It won a Space Force contract in 2023 with a $70 million ceiling. In December 2024, the Pentagon moved Ukraine’s terminals onto Starshield, covering about 3,000 units across two contracts. Ukraine’s military connections therefore run through a service that Musk now says sits under Washington’s control.

SpaceX pitches subscription model for Trump’s Golden Dome

While Musk’s post describes who holds authority, it does not infer that anyone ordered the limit, and neither SpaceX nor the US government has confirmed who set it. Ukrainian officials have pointed to the timing, which follows President Trump’s push for an energy ceasefire and Musk’s Saturday post that “Zelensky has gone too far.” The BBC noted Trump denied threatening to restrict intelligence sharing with Kyiv, and no evidence has been presented that Washington requested the cap.

The episode also revives a promise from 2025. After Poland accused him of threatening Ukraine’s access, Musk said Starlink “will never turn off its terminals” and would not be used as a bargaining chip. Poland has since supplied more than 29,000 terminals to Ukraine. Teslarati also covered Kyiv’s search for Starlink alternatives in 2025, and the latest dispute gives that search new urgency.

Tesla opens the Q&A for its biggest earnings call yet

Tesla opens its Q3 earnings Q&A, and Cybercab, Robotaxi, Optimus and regulators loom over October 21.

Tesla has opened its shareholder question portal for the Q3 2026 earnings call, with the Say Q&A page already listing questions. Investors have until 4:00 p.m. EDT on October 20 to submit and vote on what management should answer.

The call is set for Wednesday, October 21. Tesla will post results after the market closes, with a live webcast at 4:30 p.m. CT, or 5:30 p.m. ET, through its investor relations site.

Say ranks questions by the number of shares behind the votes, which gives institutional holders extra weight over the retail crowd.

Ahead of Q2, retail investors asked why Robotaxi growth had stalled, when Cybercab would start customer rides, and where the Optimus Gen 3 ramp stood, while an institutional holder asked how Tesla and SpaceX would split Terafab duties. Cybercab has since answered one of those. Tesla said last week it has 300 plus Cybercabs serving Austin, up eightfold in 30 days, with Dallas named as the next city. The questions now are likely to move from when to how fast.

There is also a regulatory question hanging over the call. NHTSA has demanded sworn answers on how the pedal free Cybercab was certified against federal safety standards, with responses due October 30, nine days after the call. Whether an analyst raises it live is unknown, but it is the kind of exposure that tends to find its way into a Q&A.

The numbers will not be the main draw. Tesla already reported 486,532 deliveries and 13.7 GWh of storage for the quarter. Consensus sits around 43 to 45 cents per share on roughly $27.8 billion in revenue, according to Zacks, after a Q2 report that missed on EPS. Goldman Sachs, which holds a Neutral rating and a $360 target, argues the outlook for Robotaxi, FSD and Optimus will matter more to the stock than the quarter itself.

The call also lands six days after the rescheduled Roadster event, which Tesla will stream on X on Thursday, October 15, at 7:55 p.m. CT. If the Roadster shows up with a production date or a SpaceX thruster package, expect it to climb the voting list before the deadline.

Ukraine says Starlink is cutting out its military drones as Poland calls out Elon Musk

Ukrainian officials allege SpaceX limited military Starlink speeds, disrupting drone missions; SpaceX has not commented.

Ukrainian officials are accusing SpaceX of placing a speed limit on the military version of Starlink that their forces use to fly drones, but SpaceX has not confirmed that any change was made. Presidential adviser Serhiy Beskrestnov said in a Telegram post on Wednesday that Starshield terminals have begun losing service when they move faster than about 100 miles per hour, according to a Reuters report. “Our defense forces did not receive a warning about this limitation, and this led to the disruption of several missions,” he wrote.

Ukraine’s 7th Rapid Reaction Corps told Reuters that connections dropped for 10 to 20 seconds at just 68 to 75 mph, which made the drones harder to control. Volunteer Serhiy Sternenko, citing military reports, said the dropouts are now starting at 37 to 43 mph. These accounts come from Ukrainian officials and military sources and have not been independently verified. Regular civilian terminals were reportedly not affected, according to EUalive.


SpaceX has not publicly commented or explained what, if anything, changed. Beskrestnov and other Ukrainian officials believe the issue is intentional and point to the timing. Washington has been pressing Kyiv to stop long range strikes on Russian oil refineries after President Trump called for an “energy ceasefire,” and Musk posted on Saturday that “Zelensky has gone too far.” EUalive noted that neither Ukrainian nor Polish officials have presented evidence that the limit was ordered by Washington or by SpaceX, so the link to politics remains an allegation. Other explanations, such as a technical or policy change affecting fast moving terminals, have not been ruled out.

Poland’s foreign minister, Radosław Sikorski, responded on X by quote tweeting a Kyiv Independent report and writing: “Hey, @elonmusk, big man, are you playing politics with your products again? As your European customers, we are watching you.” Poland is the largest funder of Ukraine’s Starlink service, having supplied more than 29,000 terminals and covering operating costs Sikorski has put at roughly $50 million a year. The wording echoes their 2025 clash, when Musk told Sikorski to “be quiet, small man.” At the time of writing, neither Musk nor SpaceX had responded to the claims.

The dispute sits on top of a long history. Musk confirmed in February 2022 that Starlink was active in Ukraine after a request from a Ukrainian minister. That October, SpaceX asked the Pentagon to share the bill and Musk said the cost was approaching $20 million a month, before he reversed course and said SpaceX would keep paying. In December 2024 the Pentagon moved some of those terminals onto the Starshield service, the government version now at the center of the complaints.

SpaceX has also changed how its network treats certain terminals in Ukraine before, and that time it was with Kyiv’s cooperation. In February, Ukrainian officials confirmed that terminals believed to be used by Russian troops were disabled after coordination with SpaceX, a step that Ukrainian commanders later said hurt Russian assaults. Whether anything similar is behind the latest reports is unclear, which is why Kyiv is asking for answers.

Ukraine is already looking at backups. Defense tech company Stetman is developing its own satellite system, UASAT-NANO, and officials in Europe have discussed alternatives to Starlink since early 2025, though none match its scale yet.
