After a busy several days of rocket hardware testing, Elon Musk says that SpaceX may be ready to build the first Starship prototype destined for space.

According to Musk, one test in particular – performed in South Texas just yesterday – is an encouraging sign that SpaceX’s Starship team is becoming increasingly competent at building the massive steel parts that will ultimately make up the generation launch vehicle. For SpaceX, the particular skills and expertise needed to precisely and consistently build a launch vehicle – let alone a rocket as large and complex as Starship – are quite a bit different from those it has mastered with Falcon 9, Falcon Heavy, and Dragon.

A lot of the expertise – particularly engineering talent, countless lessons-learned, and insight into reusability – is directly transferable from Falcon rockets to SpaceX’s Starship/Super Heavy program. Where it really isn’t transferable, however, is in the methods required to actually build the steel subcomponents that must ultimately be assembled together to form the rocket’s upper stage and booster. As a result, SpaceX has spent more than a year focused on building, testing, scrapping, improving, and re-testing any number of critical Starship components. Over the last four weeks (and last few days in particular), that testing has come to a head and Elon Musk believes the results have opened the door for SpaceX to begin building its first space-bound Starship prototypes.

SpaceX’s latest round of full-scale Starship hardware tests began just 10-20 days ago, depending on how one counts. Back around the start of the new calendar year, SpaceX began rapidly integrating two new Starship bulkheads and two cylindrical steel rings (barrel sections), ultimately delivering a finished ‘test tank’ after just 20 days of work. On January 10th, scarcely 24 hours after the two halves of the test tank were welded together, SpaceX sent the Starship test tank to its nearby launch pad and pressurized it with water until it quite literally burst.

After bursting, the test tank (like most pressure vessels) partially imploded as the liquid it contained poured out, creating a vacuum near the upper dome. (NASASpaceflight – bocachicagal)

Musk tweeted the results of that intentional test-to-destruction just a few hours after it was completed, revealing that SpaceX’s upgraded production and integration techniques enabled the tank to survive pressures almost 20% greater than the minimum Starships will need to perform orbital launches.

“Critically, the tank reached a maximum sustained pressure of 7.1 bar (103 psi), 18% more than the operating pressure (6 bar/87 psi) Musk says Starship prototypes will need to begin orbital test flights. At 7.1 bar, the test tank would have been experiencing an incredible ~20,000 metric tons (45 million lbf) of force spread out over its interior surfaces — equivalent to ~20% of the weight of an entire US Navy aircraft carrier. Perhaps even more impressive, that same Starship test tank was built from almost nothing extremely quickly, going from first weld to said pressurization test in just three weeks (20 days).

With relatively minor improvements to welding conditions and the manufacturing precision of Starship rings and domes, Musk believes that SpaceX can reliably build Starships and Super Heavy boosters to survive pressures greater than 8.5 bar (125 psi), guaranteeing a safety margin of at least 40%. Even a minor improvement of ~6% would give Starship a safety margin of 125%, enough – in the eyes of most engineering standards committees – to reasonably certify Starships for orbital test flights.”

Test Tank 2: The Tankening

This brings us to January 27th, a little over two weeks after SpaceX completed and burst the first standalone Starship test tank. Over the last week, SpaceX has quickly assembled a second Starship test tank, using a few clearly new methods and parts, as well as a brand-new tent built by the same company that Tesla used for Fremont’s fourth General Assembly line.

In the last few days, two new bulkheads and steel rings came together to form Starship test tank #2, which was subsequently prepped for transport and moved about a mile down the road to SpaceX’s launch facilities on the morning of January 27th. Scarcely a few hours later, well before anyone was paying close attention for test activities, Elon Musk took to Twitter to reveal that the second tank had already been subjected to a pressure test with water. That second tank reportedly survived up to 7.5 bar, an improvement of about 6% compared to the first tank.

This time, however, the tank wasn’t actually catastrophically destroyed by the pressure test, instead developing a leak around the weld connecting the two halves that lead SpaceX to back off. Musk says that that presumably small leak will now be repaired, after which the same tank will be tested again but with one significant difference. Musk says that Test Tank #2’s second pressure test will be performed with a cryogenic liquid — most likely liquid nitrogen (LN2).

In replies after his reveal, Musk noted that he believed the second test tank could perform significantly better if pressurized with a cryogenic liquid. That’s because certain types of steel – particularly those SpaceX has chosen for Starship – exhibit something known as cryogenic hardening when exposed to extremely cold temperatures, producing steel that can be dramatically stronger by some measures.

Ultimately, as mentioned above, a tank pressure safety margin of 125% is the minimum most engineering standards provide for any given orbital-class launch vehicle. At 7.5 bar, even under the very unlikely assumption that Starship tanks will not see even a marginal strength increase at cryogenic temperatures, SpaceX’s second Starship test tank has officially hit that 125% safety margin. As Musk himself noted on Monday, he is now confident that SpaceX can immediately start building the first Starship destined for spaceflight and further revealed that two of that particular Starship’s three tank domes are already nearing completion.

Known as Starship SN01 (serial number 01), there’s a strong possibility that the massive spacecraft will never reach higher than a 20 km (12.5 mi) flight test SpaceX intends to perform. The company’s rapidly changing strategy may very well mean that SN01 – now ‘go’ for production – could also support suborbital spaceflight testing and maybe even the first orbital Starship launch, although orbital launches will require a Super Heavy booster. Elon Musk, for one, has already christened Starship SN01 an “orbital vehicle”.

Amazon shuts out Elon Musk’s Grok Bot so he may just build his own rival store

Musk promises SpaceX will cover Grok Bot purchase errors, tells users to shop beyond Amazon.

Elon Musk said SpaceX will reimburse users if Grok Bot botches a purchase or leaks their card details. A few hours later he was telling users to take their shopping elsewhere after Amazon shut the agent out.

The first post was a reply to an X user who said Grok Bot booked him a flight after he sent a photo of his credit card. “This works well,” Musk wrote. “If Grok @Bot makes a mistake with a purchase or leaks your card (never happened yet), SpaceX will make you whole,” said Musk.

The second came after another user posted the error his Grok Bot hit on Amazon: “Continued access by an unauthorized AI agent violates Amazon’s Conditions of Use, to which our customers have agreed.” The user said his bots can no longer order from the site. Musk answered, “Just ask Grok @Bot to buy what you want someplace else and get a better deal. There are far more purchasing websites than just Amazon!” He later added, “Maybe we should start a competitor to Amazon,” a possible hint at an X shopping service.

The Amazon block did not start Thursday. A reply to Musk on October 10 said Amazon was blocking the bot, and Musk responded that Grok would find another way, then showed an order it placed on Lego’s website.

The latest reimbursement promise builds on late August when Musk told a Tesla investor weighing whether to give Grok Bot access to his bank accounts, “If Grok Bot messes up, we will make you whole,” as Teslarati covered when SpaceXAI added its Finance integration. That promise goes further than the company’s consumer terms, which make users responsible for what their agents do and generally cap liability at the greater of fees paid or $100. Neither Thursday post says those terms have changed, so for now it remains a statement on X rather than a published policy.

The two posts matter to Tesla owners because Grok Bot is no longer limited to a phone. Tesla brought it into its vehicles on September 22, and it is now enabled across every Cybercab and the rest of the Model Y Robotaxi fleet, as noted when Teslarati looked at why Grok Bot may be the Cybercab’s real advantage. A rider who asks for groceries or a coffee order is relying on retailers that let the agent in. Amazon has now said it will not, and Musk’s answer is to route around it.

Amazon has not commented publicly on the block in the posts Teslarati reviewed, and it is unclear whether Musk will follow through on a rival store.

So, how many of you do the vast majority of shopping on Amazon and hate that you do? Comment and let us know your thoughts!

Elon Musk says Tesla’s Roadster demo could be a bang, quite literally

Musk says tonight’s Roadster demo will be a banger, maybe literally. The clues add up.

Elon Musk spent Wednesday and Thursday stacking teases on top of Tesla’s Roadster event, and the wording is getting harder to read as routine hype. Tesla streams the unveil tonight at 7:55 p.m. Central on X. Musk has called it “a candidate for greatest product demo of all time,” then added that “this demo will be a BANGER, probably metaphorically, though some chance literally.”

The “some chance literally” part is the line to watch. The Roadster has been tied to a SpaceX option package since 2018, and as we reported when the date was announced, the system is reportedly codenamed A71 and uses cold gas thrusters fed by a composite overwrapped pressure vessel, the same tank design SpaceX uses on Falcon 9. Musk has said a thruster equipped car could reach 60 mph in about 1.1 seconds. Cold gas thrusters firing at full output are loud, and reports ahead of the event say the car will be unmanned with spectators kept several hundred yards back. A literal bang could simply mean a demonstration that sounds like one, though it is also an admission that something could go wrong on stage.

Then there is “Timing is everything,” which Musk posted a day earlier. Stocktwits noted that 7:55 p.m. is 19:55 on a 24 hour clock, which echoes 1955, the year Marty McFly travels to in Back to the Future. Musk has made that connection before. In 2019 he replied to an animation of a flying DeLorean by saying the new Roadster “will actually do something like this.” Nothing from Tesla confirms the movie reference, but the stream time was chosen by someone, and Tesla has not been shy about this kind of wink.

Also, Tesla said it moved the event because it “can only be held outdoors,” and Musk then wrote that the demo was postponed “due to high winds,” as Teslarati covered at the time. A car running a standing start in front of a crowd shrugs off wind. A car that leaves the ground does not. The venue near SpaceX’s McGregor test site and the FAA airspace closures reported around the original date point the same way, though we also noted the delay could be a plain safety precaution. Musk has also described the new Roadster as “beyond movies, beyond imagination, beyond human, yet still made by humans on Earth.”

The only official figures remain the 2017 ones: 620 miles of range, a top speed above 250 mph, a 1.9 second 0 to 60 time, and prices of $200,000 for the base car and $250,000 for the Founders Series. Production is expected at Giga Texas in 2027 or 2028. Tesla has said the event will cover pricing, specifications and production targets, and its livestream preview has the full rundown. Tesla reports third quarter earnings on October 21, so whatever lands tonight will be fresh going into that call. We will have live coverage as soon as the stream starts.

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.
