A SpaceX Super Heavy booster was rocked by a substantial explosion and subjected to multiple fires at the launch pad during the rocket’s latest round of testing.

As of 9 pm CDT, July 11th, the fate of the upgraded Super Heavy – known as Booster 7 or B7 – is leaning towards survival but and it won’t be certain until the rocket is drained of all cryogenic propellant and potentially flammable gas and safe for SpaceX employees to approach. The incident began around 4:20 pm CDT, when Super Heavy Booster 7 (or its launch mount) unintentionally ignited a cloud of flammable gas produced during flow test involving most or all of its 33 Raptor engines. In the past, SpaceX has performed “spin prime” tests with Raptors installed on Starship prototypes, flowing high-pressure gas through the engines’ turbines to get them up to operating speeds and pressures. Booster 7’s test ended a bit differently.

When the resulting cloud of well-mixed methane and oxygen gas was accidentally ignited, it functioned like a small fuel-air bomb, rapidly combusting to produce a violent explosion and shockwave. After the initial explosion, the fire also expanded to burn as much of the resulting gas as possible, producing a fireball that briefly reached 80-90 meters (~260-300 ft) in height. CEO Elon Musk – apparently not directly participating in the test – initially stated that the explosion and fire was planned, implying that it was more or less a nominal outcome. Virtually everyone with experience observing Starship testing felt otherwise, however.

To preserve the safety of the few local residents still living at Boca Chica Village, SpaceX is required to issue printed safety warnings well in advance of Starship tests that could create a shockwave capable of shattering glass and injuring locals. SpaceX has never intentionally performed such a test without distributing those warnings and did not distribute a warning before July 11th, all but guaranteeing that no ignition event was planned. A few hours later, Musk deleted his original tweet and posted a different one, confirming that the explosion was “actually not good” and that SpaceX is “assessing the damage.”

For the most part, Booster 7 and the Starbase Orbital Launch Site (OLS) exceeded viewers’ expectations of their sturdiness, exhibiting very little off-nominal behavior after being subjected to a unexpected explosion, shockwave, and fire. Immediately after the event, B7 quickly depressurized its propellant tanks and appeared to leave those vents open, reducing the chances of the booster destroying itself if SpaceX were to lose control. SpaceX also appeared to intentionally avoid using the orbital launch mount’s (OLM) umbilical mechanism to remove propellant from the Super Heavy’s tanks, perhaps concerned that the shockwave might have weakened its connection to B7.

Starship SN4 demonstrates one possible outcome of attempting to use a leaky pad umbilical to detank.

About an hour after the explosion, Booster 7 dumped a large amount of cryogenic liquid out of a new vent located on its aft end, producing a flood that spread around the adjacent pad. It’s unclear if that liquid was nitrogen or oxygen but either way, the emergency propellant dump appeared to cause a fire to start about 100 feet (~30m) from the booster and launch mount. That fire proceeded to burn intermittently for the next two hours, all the while posing a clear and present danger to the rest of the pad and booster if it were to spread in the wrong direction or breach the wrong underground pipe. Instead, SpaceX got lucky and the fire eventually self-extinguished.

In a worst-case scenario, Super Heavy’s engine section and 33 Raptor engines could have been seriously damaged, while the subsequent pad fire(s) could have also significantly damaged crucial pad systems, requiring weeks of repairs. The booster could even be beyond repair. More optimistically, given that SpaceX appears to have gotten lucky enough to avoid a total loss of vehicle, Booster 7 may be fine after some inspections and moderate repairs. The pad damage could also be limited to a single isolated, non-critical piece of equipment catching fire and burning to a crisp

Regardless, SpaceX will need to figure out what exactly caused the explosion and make sure that that failure mode does not appear again. In the meantime, the company recently finished stacking Super Heavy Booster 8, and Starship S24 – installed on a nearby suborbital test stand – is ready to begin its own static fire test campaign in the near future.

SpaceX announces new Starbase for ‘thousands of Starship launches annually’

Published

SpaceX announced today that it would expand its launch capabilities into a new U.S. state: Louisiana.

Today, SpaceX, in conjunction with the Louisiana Economic Development Office, said that it will establish a new launch facility, which it will call Starbase, Louisiana. It will be located near Vermilion Parish, supporting thousands of launches each year, at least eventually.

CEO Elon Musk commented by stating, “Starbase Louisiana will ultimately have over a dozen launch towers, enabling more than 30 Starship flights per day and making it the biggest launch site on Earth!”

The expansion is SpaceX’s latest move to push its launch cadence to be more frequent than ever. SpaceX said that Starbase, Louisiana, will be built to “support thousands of Starship flights a year,” with the first coming in 2029.

SpaceX announced the new facility in partnership with the Louisiana Economic Development Office as it will bring a major influx of jobs and investments into the area. Currently, it will produce more than 3,000 new jobs in Louisiana, and SpaceX plans to invest at least $100 billion into the entire facility, ensuring that many jobs are created as a result.

Environmental Responsibility

SpaceX acknowledges the impact launches could have on marshlands, local wildlife, and water sources. Here’s how the company plans to help with the issues in Vermilion Parish:

  • Restoring the Shoreline: “In Vermilion Parish, the shoreline is eroding between 3.3 and 23 feet per year. We’re partnering with state and federal agencies to expand Louisiana’s Coastal Master Plan and Coastal Wetlands Planning, Protection and Restoration Act projects, including Gulf shoreline protection breakwaters designed to reduce wave energy and slow loss along the Gulf edge.”
  • Rebuilding the Marshlands: “In working with the state, we’re planning thousands of acres of marsh creation using beneficial-use placement of dredged material and offshore sediment sources. Restoration will also include interior marsh bank stabilization and rebuilding marsh in remnant canals. These projects can reconnect fragmented wetlands, restore natural buffers against storms, and return habitat that has been lost to erosion and historic canalization.”
  • Preserving Coastal Wildlife: “Pecan Island and nearby wetlands are high-value habitat for migratory waterfowl, shorebirds, wading birds, and other coastal wildlife. SpaceX is not developing the full footprint of the land and will preserve wetlands and wildlife habitat. At existing launch sites, waterfowl and other birds continue to use nearby habitat during operations. Working with wildlife agencies, landowners, and conservation groups, SpaceX will support monitoring and management so this habitat stays productive and hunting, fishing, birding, and other recreational activities that are part of this coast’s culture can continue.”

SpaceX shares rose about 2.5 percent on the news.

Tesla just made Cybertruck more expensive

Published

Tesla Cybertruck trims saw a big price change, at least on two of the three available to consumers, as demand for the all-electric pickup appears to be increasing.

Tesla bumped up its Base All-Wheel-Drive trim level up to $74,990 from $69,990 and the Premium All-Wheel-Drive configuration from $79,990 to $84,990. The Cyberbeast price remains unchanged at $99,990.

Despite questions of demand for the truck, Tesla is bumping its two least expensive trims up $5,000 to signal that there are plenty of buyers. Although SpaceX has been buying Tesla Cybertruck units to utilize as company vehicles, it is no secret that the Cybertruck is among the most sought-after Tesla models out there.

The issue has always been pricing, at least for the most part. When Tesla initially launched the Cybertruck AWD at $59,990 a few months back, the company stated that price would remain intact for just ten days due to the influx of orders it received.

Cybertruck Sales: Is It the Product or Pricing?

Depending on who you ask, you will likely hear one of two explanations for relatively low Cybertruck sales: either the product itself or the pricing.

Yes, this is the best-selling all-electric pickup on the market. However, there are people who simply hate the look of it, which I understand, but do not agree with. Look is totally subjective, and I love the look of the Cybertruck.

Some people will not buy the Cybertruck because of the look, but I am under the impression that sales would be much better if this truck were priced lower; something that might not be possible considering Tesla’s need to make money on its products. When it was unveiled in 2019, its most expensive trim level was $69,990. Now, the cheapest trim level is more expensive than that.

I would be in a Cybertruck if it were more affordable. I LOVE my Model Y, but Cybertruck is the best vehicle Tesla makes, and it’s not particularly close. Even in the base model, the steer-by-wire, the space, storage, and performance make it more desirable than the Model Y to me. I cannot be the only Tesla owner without a Cybertruck who feels this way.

Tesla Semi factory is getting a celebration nobody expected

Tesla will inaugurate its Nevada Semi factory September 24, five months after production quietly began ramping.

Tesla says it will officially inaugurate its new Semi factory in Nevada next month. The Tesla Semi account posted the announcement on X, sharing a graphic titled “Semi Rollout” with a date of September 24. No further details were given about the format of the event or who would attend.

While Tesla’s dedicated Semi plant in Sparks, adjacent to Gigafactory Nevada, opened back in April, with the first trucks rolling off the high volume line on April 29, the timing for the factory inauguration comes at a surprise. The ribbon cutting event five months into production is a break from how Tesla has usually handled its other factories, where the first truck or car off the line typically served as the milestone moment.

The 1.7 million square foot factory was built as part of a $3.6 billion expansion Tesla announced in early 2023, and it shares a site with the battery cell lines that feed the Semi’s structural pack, a decision meant to remove the supply bottleneck that delayed the truck for years. The plant is designed for 50,000 trucks a year at full ramp. Semi program director Dan Priestley has said production “is now ramping” rather than claiming it has reached scale.

Nine years passed between the Semi’s 2017 unveiling and this stage of production, with the truck slipping from an original 2019 target through hand built pilot units for PepsiCo and a slow build out of the Nevada plant. An inauguration event now gives Tesla a stage to talk up that ramp and reset expectations for how many trucks it can begin delivering at scale.

The September date also lines up with the Semi’s next milestone. Tesla confirmed the truck is heading to Europe with a full unveiling at the IAA Transportation trade show in Hannover, Germany, running September 15 through 20. Between the Nevada event and the Hannover reveal, Tesla has roughly a week and a half in September to make the case that the Semi is now a truck being built and sold on two continents rather than tested in a handful of fleets.
