SpaceX to attempt to crush Starship test tank

A week after rolling a different ‘test tank’ from its South Texas Starship factory to nearby launch and test facilities, SpaceX has moved a second test tank to the pad.

Hearkening back to a period in 2020 where SpaceX built and tested six different Starship test tanks in a period of six months, the company appears to be preparing to test another batch of tanks in the hopes of qualifying Super Heavy booster design changes and clearing the way for a significant upgrade to all Starship tank domes. The sequencing of the latest tank raises some questions, however.

Known unofficially as the “EDOME” tank in reference to a cryptic label on the side of one of its halves, the first new test tank’s purpose is much more cut and dry. While its steel rings appear to be unchanged from current Starship and Super Heavy prototypes, the tank’s two domes share almost nothing in common with the dozens of domes SpaceX has built and tested over the last three years of development. The new domes are much simpler and should be easier to manufacture than the domes SpaceX is familiar with. Thanks to their more spherical shape, they should also be more efficient, allowing future Starship tanks to store a bit more propellant while taking up the same amount of vertical space. SpaceX has yet to begin testing the EDOME tank since its June 8th rollout and does not appear to be much closer to starting 12 days later.

On June 16th, SpaceX rolled a second test tank to the launch site, which eventually joined the EDOME tank at a staging area that used to be a Starship landing pad. Whereas the EDOME tank is more of a generic test article, the second tank – known as B7.1 – is specifically designed to test Super Heavy booster design changes.

B7.1 is a bit like a miniature Super Heavy. Its three-ring top section is mostly similar to the top section of a booster and is reinforced with dozens of external stringers. Oddly, it is missing cutouts for grid fins, and the tank’s forward dome does not have the reaction frame those hypothetical grid fins would anchor to. On the tank’s bottom half, the same stringers are present, and the tank features a new design that squeezes four slightly shorter rings into the same height as three. The Super Heavy thrust dome those rings enclose is also a new design that expands the number of central Raptor engines from 9 to 13.

It’s unsurprising that SpaceX wants to test those significant design changes. SpaceX did technically conduct a similar test in mid-2021 with a test tank known as BN2.1, but that tank featured a thrust dome with room for 9 older Raptors that would have generated about ~1700 tons of thrust. B7.1’s testing will go a step further than BN2.1 and use a structural test stand that should allow SpaceX to simulate the compressive forces Super Heavy boosters might experience in flight, adding another dimension of stress on top of the 13 hydraulic rams that will simultaneously subject the test tank to the equivalent of ~3000 tons (~6.6M lbf) of thrust.

What is surprising, however, is the fact that SpaceX has waited so long to build and test a tank like B7.1. SpaceX has already completed an entire Super Heavy booster (B7) with all the design changes B7.1 is meant will test and recently installed 33 new Raptor 2 engines on that prototype. A second upgraded booster, B8, is also nearly finished. In that sense, B7.1 is quite unusual and feels more like a reluctant afterthought than part of a methodical development process. If B7.1 suffers an unintentional failure during testing, SpaceX could be forced to abandon two nearly-finished Super Heavy boosters, wasting months of assembly and testing and rendering prototypes that are likely worth tens of millions of dollars all but useless.

The design changes B7.1 is meant to test are not exactly radical, but it’s still unclear why SpaceX has chosen to conduct those tests after building two entire Super Heavy boosters. Earlier on in Starship development, SpaceX regularly used test tanks to qualify significant design changes before applying those changes to full prototypes, limiting the amount of resources that could be wasted on any unproven prototype. Thankfully, Super Heavy Booster 7 may have already completed similar Raptor thrust simulation tests on the same test stand B7.1 was recently installed on, meaning that SpaceX’s confidence may have been well-placed. However, if the first use of the ‘can crusher’ stand on a Super Heavy test tank finds any problems or ends in failure, B7 and B8 could still be easily rendered unusable or incapable of flight, significantly delaying Starship’s first orbital launch attempt.

Lately, SpaceX has been focused on preparing Starship S24 and Super Heavy B7 for static fire tests that could eventually qualify the pair to support the first orbital test flight. It’s not clear if or when SpaceX will be able to set aside time and evacuate Starbase’s busy orbital launch site to test B7.1 or the EDOME tank.

Tesla to lose 64 Superchargers on New Jersey Turnpike in controversial decision

Tesla is set to lose 64 Superchargers on the extremely busy and congested New Jersey Turnpike.

Tesla is going to lose 64 Superchargers on the New Jersey Turnpike after a decision by the Turnpike’s governing body was made not to renew its contract with the automaker.

On Friday, Tesla revealed that the New Jersey Turnpike Authority (NJTA) had officially decided to choose a sole third-party provider for its electric vehicle infrastructure. This resulted in the NJTA not renewing its contract to keep Tesla Superchargers on the toll road.

The NJTA also requested, with its decision not to renew with Tesla, that the company decommission all 64 Supercharger stalls, an unprecedented decision that will remove these plugs from the turnpike, making charging more scarce on the busy roadway.

Tesla detailed the situation on Friday:

“The New Jersey Turnpike Authority (“NJTA”) has chosen a sole third-party charging provider to serve the New Jersey Turnpike and is not allowing us to co-locate. As a result, NJTA requested 64 existing Supercharger stalls on the New Jersey Turnpike to not be renewed and be decommissioned.”

Tesla said it has been preparing for the potential that the Turnpike Authority would make this decision for three years by building 116 Superchargers nearby to still supply drivers with reliable charging infrastructure.

The company also noted that its Trip Planner would adjust automatically.

There were also efforts to maintain a relationship that would benefit both the Turnpike and EV drivers who use it.

Tesla said it offered the NJTA various “above-market commercial items,” like an offer to build Superchargers at all New Jersey Service Plazas with equipment upgrades like screens and adapters for those companies who have gained access to its charging piles but need to utilize the NACS and CCS1 plugs.

The decision is one that seemed to baffle the company, especially as infrastructure is one of the biggest concerns among EV skeptics:

“Tesla always advocates for more infrastructure and co-location with additional third-party charging providers. This drives down costs through optionality, and accelerates EV adoption by having sufficient capacity to shoulder peaks. We expect that ~30 times more fast-charging capacity is needed to get to full EV adoption. NJTA’s decision to remove, rather than add, critical charging infrastructure is a setback for New Jersey’s EV adoption goals of 100% Zero-Emission New Car Sales by 2035. It removes Turnpike access to the most reliable (99.9% uptime), least congested (<1% waiters) and cost-effective (~30% lower $/kWh) charging. “

The company said it was more than willing to invest in Turnpike sites if the Authority or New Jersey Governor Phil Murphy wanted to reverse the decision.

SpaceX hit with mishap investigation by FAA for Starship Flight 9

Starship’s ninth test flight has the FAA requiring a mishap investigation from SpaceX.

SpaceX has been hit with yet another mishap investigation by the Federal Aviation Administration (FAA) related to the company’s ninth test flight of Starship earlier this week.

The FAA said the mishap investigation is “focused only on the loss of the Starship vehicle, which did not complete its launch or reentry as planned.” The agency said the loss of the Super Heavy booster is covered by one of the FAA’s approved test induced damage exceptions requested by SpaceX.

All of Starship and Super Heavy booster debris landed within the designated hazard areas, the FAA confirmed.

It said it activated a Debris Response Area out of an abundance of caution as the booster “experienced its anomaly over the Gulf of America during its flyback toward Texas. The FAA subsequently determined the debris did not fall outside of the hazard area. During the event there were zero departure delays, one flight was diverted, and one airborne flight was held for 24 minutes. ”

SpaceX has become accustomed to mishap investigations by the FAA, as they have been impacted by them on several occasions in the past, including on Flight 8. However, they are a precautionary measure and usually are resolved within a few weeks.

Flight 9 was one of SpaceX’s most eventful, as there were several discoveries during the launch. First, it was SpaceX’s first time reusing a Super Heavy booster, as the one utilized for Flight 9 was also used on Flight 7 in January.

Contact with the booster and Starship were both lost during Flight 9. SpaceX said the booster was lost “shortly after the start of landing burn when it experienced a rapid unscheduled disassembly approximately 6 minutes after launch.”

Meanwhile, Starship was set to make a splashdown in the Indian Ocean, but the vehicle was lost about 46 minutes into the flight, SpaceX said in a mission recap.

It was an improvement from the previous two flights, as both 7 and 8 resulted in the loss of Starship after just a few minutes. Flight 9 lasted considerably longer. These flights are also not intended to make it to Mars, despite what other reports might try to tell you.

These are ways to gain information for when SpaceX eventually tries to get Starship to Mars.

Tesla bull writes cautious note on Robotaxi launch: ‘Keep expectations well contained’

Morgan Stanley’s Adam Jonas is more cautious about Tesla’s upcoming Robotaxi launch.

Tesla analyst Adam Jonas of Morgan Stanley is telling investors to be wary of the Robotaxi details CEO Elon Musk revealed this week, after a report seemed to land on the prospective launch date of the platform in June.

Earlier this week, a report from Bloomberg indicated Tesla had internally landed on a tentative date of June 12 for its Robotaxi launch in Austin. Shortly after, Musk detailed the successful testing Tesla has already performed without anyone in the driver’s seat.

He also indicated Teslas would self-deliver to customers in June.

Analysts are now sending out investor notes on the announcement Musk made, along with the Bloomberg report. Jonas’s note is more cautious than others.

Jonas believes Tesla needs to shed more details before investors and fans of the company get too excited. He believes there is more information that could be released, but until then, he is suggesting investors “keep expectations well contained.”

He wrote:

“As is typical for highly anticipated Tesla events, we would keep expectations well contained for the (reported) June 12th Cybercab launch event in Austin. However, we would look for a continued stream of updates for the performance and growth of the network thereafter (numbers of cars, miles, trips, etc.) in the days and weeks that follow.”

The tone of Jonas’s note contradicts that of Wedbush’s Dan Ives, who believes the “golden age of autonomous” lies in Tesla’s hands. He seems to believe Tesla will come through on its June 12 launch.

Morgan Stanley’s note is slightly more

Jonas is obviously still bullish, but is much more tentative to move forward with an attitude that communicates skepticism about what Tesla has revealed.

Jonas and Morgan Stanley have a $410 price target on Tesla shares with a ‘Buy’ rating. Tesla stock is trading at around $358 at 12:15 p.m. on the East Coast.
