According to SpaceX CEO Elon Musk, the next round of Starhopper activity will focus on removing the spacecraft prototype’s tethers and performing far more substantial hop tests.

Longer tests demand that SpaceX begins expanding the known performance envelope of its full-scale Raptor engine. Towards that end, longer-duration tests would need to be done at the company’s McGregor, TX development facilities to reduce risk, tests that Musk confirmed are already well underway. A recent Raptor static fire reportedly lasted no less than 40 seconds, more than enough time for a single-engine Starhopper to significantly expand both the maximum altitude and velocity of future hop tests. In support of the upcoming Starhopper test campaign, significant construction work is also ongoing at SpaceX’s Boca Chica test and development facilities.

Unleashing the Hopper

During the months of March and April, SpaceX’s South Texas team effectively completed Starhopper and put the prototype through its first real tests. The process began with tank proof tests in which Starhopper’s tanks were filled with liquid nitrogen – relatively neutral and unreactive – to safely identify and repair any leaks, while also subjecting the vehicle to cryogenic temperatures. The proof testing also put the newly installed ground systems (GSE) and vehicle-pad connection hardware through their paces before moving to Starhopper’s nominal liquid oxygen and liquid methane propellant.

Following at least half a dozen or so wet dress rehearsals (WDRs) that saw Starhopper loaded with LOx and methane, SpaceX technicians analyzed the health of the prototype and soon began live tests with a Raptor engine installed. Designed to produce no less than 2000 kN (450,000 lbf, 205 mT) of thrust at full throttle, Raptor offers more than twice the max thrust of the latest variant of the Merlin 1D engine that powers Falcon 9 and Heavy (941 kN or 212,000 lbf). In other words, a single Raptor should be more than enough to lift Starhopper off the ground 150+ tons of propellant aboard.

In the above tweets, Musk indicates that Starhopper’s next step will be untethered hop tests powered by one Raptor engine. This is further supported by confirmation that Raptor completed its longest static fire test yet on April 27th.

After several unsuccessful test attempts, Starhopper completed two static fires (<10s combined) and hopped – tethered – a handful of feet off the ground on April 3rd and 5th, three weeks after Raptor was first installed. Days later, the lone Raptor engine was removed from Starhopper and shipped back to SpaceX’s Hawthorne, CA factory or McGregor, TX testing facilities for post-test analysis and inspection. In short, SpaceX used Starhopper as a sort of ad hoc test stand for the second serial Raptor (SN02) produced, completing two major acceptance tests simultaneously.

A handful of concise tweets published by Musk in the last few days of April implicitly confirmed that the next steps for Starhopper involved untethered flights off its South Texas pad, once again powered by a single Raptor engine. As both the prospective altitudes and flight times rise for future Starhopper tests, so do the risks posed to SpaceX’s adjacent facilities and the prototype itself. To minimize those risks and progress the Raptor program as a whole, SpaceX has been extensively testing the third serial Raptor (SN03) at its McGregor facilities. Instead of a rushed test regime similar to the one that almost completely destroyed Raptor SN01 less than two weeks after testing began, SN03 is participating in a more cautious and systematic series of tests.

Confirmed by Elon Musk, this included significantly increasing the length of Raptor SN03’s latest static fires, culminating in an April 27th test that lasted ~40 seconds. Above all else, long test fires are necessary to demonstrate that Raptor can reliably operate for dozens of seconds at a time, given that any failure leading to a loss of thrust could cause Starhopper – basically a controlled explosive device – to fall out of the sky. The famous Musk/SpaceX ethos of moving fast and breaking things does not preclude a pragmatic attitude towards the destruction of facilities and prototypes that could take months and millions of dollars to rebuild.

The ETA of future hop tests is unclear. For the time being, it appears that SpaceX’s South Texas facilities will be caught up in construction work for at least another week. Whether or not Raptor SN03 is next in line for installation on Starhopper, SpaceX will likely put it through several more long-duration static fires before moving ahead with untethered hop tests. All things considered, the rough Starship prototype is unlikely to restart powered testing for another two or so weeks. Stay tuned!

Tesla tops American-Made Index for sixth-consecutive year

Published

Tesla is atop the American-Made Index from Cars.com for the sixth-straight year, as the Model 3 and Model Y took the top two spots, respectively.

Last year, the Model 3, Model Y, Model S, and Model X took the top four spots, respectively. The company has routinely performed well in the Index. However, Tesla discontinued its flagship Model S and Model X earlier this year, which took the two cars out of the ranking.

Cybertruck is not considered due to its curb weight being above the 8,500-pound threshold, which eliminates it from being required to have more detailed assembly information.

Cars.com uses five main categories to develop its rankings:

  • Location(s) of final assembly
  • Percentage of U.S. and Canadian parts
  • Countries of origin for all available engines
  • Countries of origin for all available transmissions
  • U.S. manufacturing workforce

These five major factors are then put into a 100-point scale. The vehicles with the highest scores sit atop the list. The Model 3 edged out the Model Y.

Tesla uses a strong domestic strategy to build its cars and parts domestically. It relies on intense vertical integration that reduces its dependence on global suppliers, keeping more value and jobs in the United States.

This strategy has helped Tesla gain a strong reputation for domestically produced vehicles and parts. However, it helps it with more than just awards like this one. Keeping a supply chain local has also helped insulate Tesla more than others from tariffs and supply chain disruptions.

This year’s American-Made Index from Cars.com studied nearly 400 vehicles from the 2026 model year. Tesla was the only manufacturer to have an EV inside the Top 10. The Kia EV9 was the next EV to make the list, scoring the 17th position.

The Hyundai IONIQ 5 was 21st, and the final EV to make the list was the Cadillac LYRIQ in 77th.

Tesla finally clarifies fatal Texas crash, confirms driver manually overrode acceleration

Tesla has finally clarified the situation regarding the viral crash in Texas where a Model 3 slammed into a home.

CEO Elon Musk replied to reports on Monday that stated the crash was due to the company’s Full Self-Driving or Autopilot suite, which seemed unlikely to those who are familiar with it. Video showed the car slamming into a house at an excessive rate of speed, making it highly unlikely the crash was due to the suite’s operation, as it does not travel at those speeds in residential areas.

Musk said:

“This makes no sense. FSD drives slowly through neighborhood streets, and this was a high-speed crash!”

Tesla’s Head of AI, Ashok Elluswamy, added context, revealing that the company’s data shows the driver “manually overrode self-driving by pressing the accelerator all the way to 100%.”

He revealed the speed reached by the car was 73 MPH, and the accelerator was still pressed “even after the crash.”

Authorities are reportedly investigating “whether Tesla’s Autopilot system played a role after a Model 3 left the roadway…slammed through a brick house at high speed and fatally struck Matha Avila as she sat inside,” the New York Post reported.

The National Highway Traffic Safety Administration (NHTSA) is now investigating the crash. Tesla will work with the agency to provide them with whatever information they need in order to clarify the cause of the crash.

Similarly, Tesla had claims of a fatal accident in Harris County, Texas, a few years ago. Early reports indicated that Full Self-Driving was the cause of the crash. After the National Transportation Safety Board (NTSB) worked with Tesla, the agency proved there was “no use of the Autopilot system at any time during this ownership period of the vehicle, including the time frame up to the last transmitted timestamp on April 17, 2021.”

Tesla alleged “driverless” crash in Texas: What is known so far

“Application of the accelerator pedal was found to be as high as 98.8 percent,” the NTSB said in their findings. The highest recorded speed in the five seconds leading up to the impact was 67 miles per hour. The area where the crash occurred is residential, and Texas State laws have default speed limits of 30 MPH in residential streets.

This appears to be a similar situation. However, an investigation will prove what happened for sure.

SpaceX makes $20 billion move to optimize its balance sheet

Published

SpaceX announced today that it commenced its first-ever public bond offering, marking a significant step in the newly public company’s capital markets strategy.

The company announced an offering of senior unsecured notes expected to raise at least $20 billion.

The move comes just a short time after SpaceX completed one of the largest initial public offerings in history. In mid-June, the company priced shares at $135 and raised more than $85 billion, propelling founder Elon Musk’s net worth past the trillion-dollar mark and giving the firm substantial liquidity.

According to the company’s SEC filing, the net proceeds from the notes will be used primarily to repay in full the outstanding borrowings under its existing bridge loan facility, cover related fees and expenses, and fund general corporate purposes. The offering is being conducted under Rule 144A, as well as Regulation S, targeting qualified institutional buyers and non-U.S. investors. Notes will be unsecured obligations ranking equally with other unsubordinated debt.

The $20 billion bridge loan was used to refinance approximately $17.5 billion in higher-cost “junk” debt tied to X and xAI. SpaceX had merged with xAI in February 2026 in an all-stock deal. The bridge facility, which matures in September 2027, had represented the bulk of SpaceX’s long-term debt.

SpaceX officially acquires xAI, merging rockets with AI expertise

In connection with the bond launch, SpaceX disclosed it held approximately $100.8 billion in cash and cash equivalents as of June 19. Investor calls began on the announcement date, with pricing and launch expected shortly thereafter. Rating agencies have assigned investment-grade ratings to the proposed bonds, reflecting confidence in SpaceX’s dominant position in commercial launches and the growth trajectory of its Starlink internet offering.

The debt raise also allows SpaceX to optimize its balance sheet by replacing short-term, higher-cost bridge financing with longer-date, lower-cost fixed-income securities. This provides greater financial flexibility to support capital-intensive initiatives, including the development of Starship, the expansion of the Starlink constellation, and the integration of AI capabilities following the xAI combination.

SpaceX shares (NASDAQ: SPCX) fell sharply on the news, dropping over 16 percent overall on the market on Monday. The stock had surged initially after debuting but pulled back amid profit-taking and broader market dynamics.

Overall, the bond offering underscores SpaceX’s transition to a mature public company with access to diverse funding sources. It positions the firm to pursue its long-term vision of multiplanetary expansion and AI infrastructure, while maintaining a disciplined approach to its capital structure in a high-growth but capital-heavy industry.
