SpaceX’s thin-skinned Starship ‘test tank’ passes first trial
CEO Elon Musk says that a new thin-skinned Starship ‘test tank’ just passed its first trial, taking advantage of delays to Starship SN9’s planned high-altitude launch debut.
Delayed by a lack of FAA approval for unknown reasons, Starship SN9’s 12.5-kilometer (7.8 mi) launch debut (virtually identical to SN8’s 12.5 km launch last month) is in limbo pending an “FAA review” according to Musk. SpaceX thus found itself with at least 24 hours of guaranteed inactivity for Starship SN9, time the company rapidly chose to fill with crane transportation and, more importantly, the first Starship ‘test tank’ stress test in months.
Known as Starship SN7.2, SpaceX’s latest ‘test tank’ is the third to carry the SN7 moniker and appears to have been built primarily to test refinements to the rocket’s structural design. Following test tanks SN7.0 and SN7.1, both used to qualify the use of a new steel alloy on an otherwise unchanged design, SN7.2 – likely built out of the same alloy – is instead focused on determining if SpaceX can begin trimming the margins of an increasingly mature technology.
Curiously, SN7.2 is a sort of fusion of its predecessors: combining the stout stature of SN7.0 with SN7.1’s use of an aft thrust dome, but without SN7.1’s Starship-style skirt (the three rings at its bottom). Welded directly to its black test stand, it’s unclear why SpaceX chose to give SN7.2 a thrust dome, given that the thrust of Raptor engines can only be simulated with hydraulic rams if the tank is installed on one of two Starship launch mounts.
Regardless, whether SpaceX actually tests that aspect of SN7.2, the tank’s most important task is determining if future Starships (and perhaps Super Heavy boosters) can be built out of thinner, lighter steel rings. Its domes appear to be identical to past ships but writing on the exterior of the tank strongly implied that its three rings were built out of 3mm steel rather than the 4mm sheets that have made up every Starship built in the last 12 months.
SpaceX began loading the thin-skinned tank with liquid nitrogen (used to simulate cryogenic propellant without the risk of an explosion) around 9am CST and spent around three hours performing an “initial pressure test.” It’s unclear what that test entailed but it most likely involved raising the tank’s internal pressure to levels achieved by SN7.0 and SN7.1 Musk has previously said that that 6 bar was the bare minimum necessary for orbital flight, translating to 7.5-8.5 bar to achieve an industry-standard safety margin of 25-40%.
That SN7.2 survived that initial pressure test bodes well for the significant mass reductions SpaceX will need to optimize Starships for efficient orbital flight, potentially shaving 5-10 metric tons off the dry mass of future ships. For orbital rocket stages, every single kilogram of mass reduction translates to an extra kilogram of cargo capacity, whereas boost stages (i.e. Super Heavy) offer far more lenient ratios on the order to 10:1, meaning that adding 5-10 kilograms of rocket hardware reduces maximum payload capacity by just ~1 kg.
Depending on when SpaceX is allowed to launch Starship SN9, the company’s next test could involve pressurizing SN7.2 until it bursts, determining if the tank’s thinner skin substantially impacts its performance as a pressure vessel.

SpaceX to launch Starlink V2 satellites on Starship starting 2027
The update was shared by SpaceX President Gwynne Shotwell and Starlink Vice President Mike Nicolls.
SpaceX is looking to start launching its next-generation Starlink V2 satellites in mid-2027 using Starship.
The update was shared by SpaceX President Gwynne Shotwell and Starlink Vice President Mike Nicolls during remarks at Mobile World Congress (MWC) in Barcelona, Spain.
“With Starship, we’ll be able to deploy the constellation very quickly,” Nicolls stated. “Our goal is to deploy a constellation capable of providing global and contiguous coverage within six months, and that’s roughly 1,200 satellites.”
Nicolls added that once Starship is operational, it will be capable of launching approximately 50 of the larger, more powerful Starlink satellites at a time, as noted in a Bloomberg News report.
The initial deployment of roughly 1,200 next-generation satellites is intended to establish global and contiguous coverage. After that phase, SpaceX plans to continue expanding the system to reach “truly global coverage, including the polar regions,” Nicolls said.
Currently, all Starlink satellites are launched on SpaceX’s Falcon 9 rocket. The next-generation fleet will rely on Starship, which remains in development following a series of test flights in 2025. SpaceX is targeting its next Starship test flight, featuring an upgraded version of the rocket, as soon as this month.
Starlink is currently the largest satellite network in orbit, with nearly 10,000 satellites deployed. Bloomberg Intelligence estimates the business could generate approximately $9 billion in revenue for SpaceX in 2026.
Nicolls also confirmed that SpaceX is rebranding its direct-to-cell service as Starlink Mobile.
The service currently operates with 650 satellites capable of connecting directly to smartphones and has approximately 10 million monthly active users. SpaceX expects that figure to exceed 25 million monthly active users by the end of 2026.

Elon Musk’s xAI and X to pay off $17.5B debt in full: report
The update was shared initially in a report from Bloomberg News, which cited people reportedly familiar with the matter.
Elon Musk’s social platform X and artificial intelligence startup xAI are reportedly preparing to repay approximately $17.5 billion in outstanding debt in full.
The update was shared initially in a report from Bloomberg News, which cited people reportedly familiar with the matter.
Morgan Stanley, which arranged the debt financing for both companies, has reportedly informed existing lenders that X and xAI plan to pay back the full amount of the $17.5 billion debt. Bloomberg’s sources did not disclose where the capital for the repayment would be coming from.
X, formerly known as Twitter, assumed roughly $12.5 billion in debt during Musk’s acquisition of the company. xAI separately borrowed about $5 billion through bonds and loans last June. The two firms merged last year under xAI Holdings.
Bloomberg noted that portions of the debt are relatively recent and may carry early repayment penalties. xAI’s $3 billion in high-yield bonds are expected to be redeemed at 117 cents on the dollar, reflecting a premium since the debt was expected to stay outstanding for at least two years.
X has been servicing tens of millions of dollars in monthly debt payments, while xAI has reportedly been burning approximately $1 billion in cash per month as it invests heavily in data centers, chips, and AI talent. That being said, xAI also concluded a funding round in January, where it raised $20 billion of new equity.
The repayment plans come as Musk consolidates several of his businesses. SpaceX recently acquired xAI, making it a subsidiary as the company explores plans for space-based data centers. The combined entity has been valued at approximately $1.25 trillion.
Bloomberg previously reported that SpaceX is targeting a confidential IPO filing as soon as this month, potentially positioning the private space firm for a public listing later this year. Representatives for Morgan Stanley declined to comment, and X and xAI did not immediately respond to requests for comment.

Tesla Giga Berlin head calls out Handelsblatt’s claimed 2025 production figures
Andre Thierig, Senior Director of Manufacturing at Giga Berlin, published a detailed post on LinkedIn challenging several points made in the publication’s coverage of the Grünheide facility.
Tesla Gigafactory Berlin’s plant manager has publicly pushed back against recent reporting by German business publication Handelsblatt, which cited reportedly erroneous data about the factory’s production figures and financial performance.
Andre Thierig, Senior Director of Manufacturing at Giga Berlin, published a detailed post on LinkedIn challenging several points made in the publication’s coverage of the Grünheide facility.
In his LinkedIn post, Thierig called out Handelsblatt’s claim that 149,000 Model Y vehicles were produced at Giga Berlin in 2025. He noted that “the article is simply filled from front to back with false information and claims!
“I have to set the record straight here! In the last article about Tesla in Grünheide, the Handelsblatt speaks e.g. of 149,000 Model Ys built in 2025. WRONG!
“In 2025, we again produced over 200,000 vehicles. And this despite the fact that we stopped production in Q1 for the changeover to the new Model Y and then ramped it up again to 5,000 units per week over several weeks,” Thierig wrote.
He added that production increased each quarter in 2025 compared to the prior quarter and stated that more than 700,000 Model Y units have been produced at Grünheide since manufacturing began in 2022. For the first quarter of 2026, he stated that the factory is planning another production increase compared to the fourth quarter of 2025.
Thierig also questioned Handelsblatt’s reported 0.74% profit margin, writing that how the publication calculated the figure “remains reserved for their secret ‘calculation skills.’”
Beyond production data, Thierig highlighted Tesla’s broader footprint in Germany, stating that the company has invested more than €5 billion in Grünheide since 2020 and created nearly 11,000 permanent, above-tariff jobs. He added that Tesla is currently investing nearly €100 million into battery cell production at the site, which is expected to generate several hundred additional positions.
In a follow-up comment, Thierig noted that he did communicate with the publication’s editor-in-chief in an effort to “start fresh,” but he was informed that Handelsblatt’s current approach works just fine.
“Last year, I spoke to a representative of the Handelsblatt editor-in-chief and suggested that we “start anew” again. Handelsblatt turned down this offer on the grounds that their current approach works well for them,” Thierig noted.
Sönke Iwersen, Head of Investigative Research at Handelsblatt, responded to Thierig’s post, stating that the newspaper’s figures were based on Tesla’s own annual financial statements for the Grünheide entity.
He cited reported 2024 revenue of €7.68 billion, operating profit of €156.8 million, and net income after taxes of €55.6 million. Iwersen also referenced prior public comments from Elon Musk about Cybertruck demand, noting the gap between reported pre-orders and subsequent annual sales figures.
He also stated that the works council election eligibility figures Giga Berlin had dropped to 10,703 employees today from 12,415 two years ago.
“As far as production figures are concerned, these are figures from the data service provider Inovev. This is also stated in the article. Please compare this with Elon Musk’s information on demand for the Cybertruck. According to Musk, there were one million pre-orders. In the first year, 39,000 units were sold, in the second year 20,000. How can this be explained? With a million pre-orders?
“You yourself have repeatedly pointed out in recent months that no jobs would be cut in Grünheide because Tesla is different from the competition. Now a new works council is being elected in Grünheide. 10,703 people are eligible to vote. Two years ago, 12,415 people were eligible to vote. So there were exactly 1712 fewer from 2024 to 2026,” Iwersen wrote.
