An in-flight rocket engine failure during SpaceX’s March 18th Starlink launch could pose a threat to the company’s imminent NASA astronaut launch debut according to a statement provided by the space agency yesterday.

SpaceX and NASA are currently working around the clock to prepare a Falcon 9 rocket and Crew Dragon spacecraft for the company’s inaugural astronaut launch, a flight known as Demonstration Mission 2 (Demo-2/DM-2). All launch vehicle and spacecraft hardware – including booster B1058, an expendable upper stage, a spacecraft trunk, and the Crew Dragon capsule itself – are already believed to be at SpaceX’s Florida launch and processing facilities.

Prior to March 18th, the biggest gating items were believed to be a few final parachute tests and a whole lot of paperwork and reviews, as well as some important but less showstopping astronaut training. Unfortunately, SpaceX has suffered two unforeseen issues of varying severity in the last few days, both of which are now all but guaranteed to impact Crew Dragon’s astronaut launch debut schedule.

“According to the CCtCap contracts, SpaceX is required to make available to NASA all data and resulting reports. SpaceX, with NASA’s concurrence, would need to implement any corrective actions found during the investigation related to its commercial crew work prior to its flight test with astronauts to the International Space Station. NASA and SpaceX are holding the current mid-to-late May launch timeframe, and would adjust the date based on review of the data, if appropriate.”

On March 18th, less than three minutes after liftoff and shortly before stage separation was scheduled, Falcon 9 booster B1048 – on its historic fifth launch attempt – suffered an engine failure visible on SpaceX’s official webcast. By all appearances, Falcon 9’s autonomous flight computer accounted for the engine’s failure, shutdown, and the resultant loss of thrust by burning B1048’s eight remaining engines for several seconds longer than planned.

While that extra few seconds of burn time likely ensured that the rocket’s upper stage was able to make it to the correct orbit after stage separation, roughly five minutes after B1048’s extremely rapid engine failure, contact was lost. For the first time ever, there were no landing burn-related call-outs from SpaceX launch operators, the first sign that something was seriously wrong. A few minutes later, SpaceX’s webcast hosts acknowledged that the booster had been lost, perhaps lacking the propellant it needed to attempt a landing.

For reference, Merlin 1D engines likely consume some ~270 kg (600 lb) of fuel each second. Falcon 9’s landing propellant reserves are believed to be on the order of 50+ metric tons (110,000 lb). Excluding the failed engine, eight Merlin 1Ds burning at full thrust for an additional 5 seconds would consume 20% of the propellant needed for landing; 10 seconds and it would use 40%.

The anomaly was Merlin 1D engine’s first in-flight failure ever. The 2012 failure of one of an original Falcon 9 V1.0’s rocket’s nine Merlin 1C engines is SpaceX’s only other in-flight failure.

It’s likely that B1048’s engine failure was primarily related to the fact that the booster was SpaceX’s pathfinder for a fifth-flight reusability milestone, making it the most reused rocket booster ever launched. NASA currently requires all of its Crew Dragon missions to launch on new Falcon 9 rockets, hopefully mitigating direct corollaries between the Starlink L6 anomaly and astronaut launches. Regardless, the space agency says that the company will now have to complete its internal failure review and implement necessary hardware, software, or rule changes before it’s allowed to launch NASA astronauts.

In a major twist, NASA has effectively confirmed that SpaceX will become the first private company in history to launch astronauts into orbit. (SpaceX)

That investigation could take a matter of weeks, possibly even less, but it’s entirely possible that it could take months – let alone fixing the problems that allowed the in-flight Merlin 1D engine failure to happen in the first place. Ultimately, it will almost certainly make even the first flights of Falcon 9 and Heavy rocket boosters safer, but it could substantially delay SpaceX’s Demo-2 astronaut launch debut. Still targeted no earlier than (NET) mid-to-late May 2020, it’s safe to say that it’s reasonable to expect that schedule to slip over the next 4-6 weeks. Stay tuned for updates.

Cantor Fitzgerald maintains Tesla (TSLA) ‘Overweight’ rating amid Q2 2025 deliveries

Cantor Fitzgerald is holding firm on its bullish stance for the electric vehicle maker.

Cantor Fitzgerald is holding firm on its bullish stance for Tesla (NASDAQ: TSLA), reiterating its “Overweight” rating and $355 price target amidst the company’s release of its Q2 2025 vehicle delivery and production report. 

Tesla delivered 384,122 vehicles in Q2 2025, falling below last year’s Q2 figure of 443,956 units. Despite softer demand in some countries in Europe and ongoing controversies surrounding CEO Elon Musk, the firm maintained its view that Tesla is a long-term growth story in the EV sector.

Tesla’s Q2 results

Among the 384,122 vehicles that Tesla delivered in the second quarter, 373,728 were Model 3 and Model Y. The remaining 10,394 units were attributed to the Model S, Model X, and Cybertruck. Production was largely flat year-over-year at 410,244 units.

In the energy division, Tesla deployed 9.6 GWh of energy storage in Q2, which was above last year’s 9.4 GWh. Overall, Tesla continues to hold a strong position with $95.7 billion in trailing twelve-month revenue and a 17.7% gross margin, as noted in a report from Investing.com.

Tesla’s stock is still volatile

Tesla’s market cap fell to $941 billion on Monday amid volatility that was likely caused in no small part by CEO Elon Musk’s political posts on X over the weekend. Musk has announced that he is forming the America Party to serve as a third option for voters in the United States, a decision that has earned the ire of U.S. President Donald Trump.

Despite Musk’s controversial nature, some analysts remain bullish on TSLA stock. Apart from Cantor Fitzgerald, Canaccord Genuity also reiterated its “Buy” rating on Tesla shares, with the firm highlighting the company’s positive Q2 vehicle deliveries, which exceeded its expectations by 24,000 units. Cannacord also noted that Tesla remains strong in several markets despite its year-over-year decline in deliveries.

Tesla Sweden responds to car magazine’s claims that Model 3 has deficient brakes

The company stated that it would be examining the two Model 3s that were used in the magazine’s test.

Tesla Sweden has responded to a car magazine’s claims that the new Model 3 sedan has “deficient” brakes. The all-electric sedan was subjected to the publication’s tests, and its braking distance was reportedly found to be lacking. 

The car magazine’s tests

As noted in a report from Swedish car magazine Teknikens Värld, the new Model 3 Long Range’s braking distance proved subpar when it was tested, with the vehicle reportedly having a braking distance of a whopping 133.2 feet (40.6 meters). The magazine claimed that it repeated the test with another Model 3, and its results were only 5 feet (1.5 meters) better. 

The magazine noted that this was unacceptable since an acceptable braking distance is 124 feet (28 meters), which also happens to be the Model 3’s braking distance when it was tested by Edmunds in the United States. The publication also stated that the Volkswagen ID.7 Tourer, which is equipped with drum brakes at the rear, had a braking distance that’s 16 feet (5 meters) shorter in its tests. 

Tesla Sweden’s response

Tesla Sweden responded to the car magazine’s claims, stating that the all-electric sedan’s alleged braking performance was not consistent with the company’s data, nor does it align with the Model 3’s safety ratings. The company also noted that it would be examining the two Model 3s that were used in the magazine’s test. 

“In the latest braking tests with Model 3, which were conducted by Teknikens Värld 2021, a braking distance of 36.5 meters was measured for Model 3 RWD and 36.7 meters for Model 3 Long Range AWD, so these results are not recognized or consistent with our internal tests.

“We are examining the two specimens to find out why the braking distances differ. Safety is number one at Tesla. Model 3 comes with all safety features as standard. Independent crash safety organization Euro NCAP recently announced new crash results for cars tested in May 2025. Euro NCAP gives the upgraded Model 3 a 5 out of 5-star safety rating and an overall score of 90%, making Model 3 one of the safest vehicles tested under the latest and most stringent testing protocol ever,” Tesla Sweden stated.

Teknikens Värld digs its heels

While Tesla Sweden has responded to its allegations, the car magazine noted that it will nonetheless stand firm on its claim that the new Model 3 has deficient brakes. 

“The fact that the Model 3 previously passed the brake test is not relevant because today’s generation of the Model 3 is to be considered a new generation, as Tesla themselves often point out. Nor is the result in Euro NCAP relevant because they are different tests. We can therefore conclude that Tesla has deficient brakes on the new Model 3. It is good for everyone to know,” the car magazine wrote.

Trump pushes back on Elon Musk’s America Party, calls third-party move ‘ridiculous’

The clash marks a notable shift in the relationship between the two former allies.

United States President Donald Trump sharply criticized Elon Musk’s decision to launch a new political party, calling the move “ridiculous” and dismissing it as a distraction from the two-party system. The rebuke came shortly after Musk announced the formation of the “America Party,” aimed at disrupting what he calls the entrenched Republican-Democrat “Uniparty.”

Tensions escalate between Trump and Musk

The clash marks a notable shift in the relationship between the two former allies. Musk previously headed the Department of Government Efficiency (DOGE) under Trump’s administration, a position aimed at cutting federal spending. The alliance, however, appears to have fractured over policy differences, particularly Trump’s “Big Beautiful Bill,” which Musk notes will increase the country’s debt by $5 trillion.

Speaking to reporters on Sunday before boarding Air Force One, Trump said, “It’s always been a two-party system and I think starting a third party just adds to the confusion.” Hours later, he posted on Truth Social that Musk had gone “off the rails,” accusing him of promoting an “Electric Vehicle Mandate” that would have required all Americans to switch to EVs in a short timeframe. 

Trump emphasized that his latest tax bill deliberately excluded incentives for electric vehicles, saying Americans should be free to choose gasoline-powered, hybrid, or other new technologies without federal mandates, according to a report from the BBC.

Musk outlines goals for America Party

Musk has been open about his support for ending the EV tax credit, as long as the incentives for other industries like oil and gas are removed as well.. The CEO has adopted this stance for several years. He has also not supported the idea of a mandate that forces consumers to purchase electric cars.

Musk also stated that the newly formed America Party will focus on congressional races in 2025 and 2026, rather than fielding a presidential candidate in the near term. In his post on X, the Tesla and SpaceX CEO criticized both major parties for contributing to the national debt. He also noted that the Department of Government Efficiency’s work will be rendered useless if the US’ debt increases due to Trump’s Big Beautiful Bill.
