SpaceX has decided to install a different Raptor engine on its fourth full-scale Starship prototype in the buildup to the next-generation rocket’s inaugural flight test.

Starship SN4 recently became the first prototype to pass a cryogenic proof test, followed by two successful Raptor engine static fire tests and an even more successful pressure test on May 9th. Set to occur as early as later this month, that string of successes means that Starship SN4 is now all but guaranteed to become the first prototype to take flight. According to photos and information from CEO Elon Musk and FCC filings, that first hop – regardless of the ship – will be powered by a single off-center Raptor engine and likely follow in the footsteps of Starhopper, targeting a max hop height of 150m (~500 ft).

This time around, though, Starship SN4 will be around twice as tall as Starhopper, making for quite a spectacle regardless of the outcome. Currently, SpaceX has already received FCC authorization for Starship communications and is mainly just waiting on FAA approval for the short hop test – a license to launch that Musk suggested could arrive more than a “few weeks” after April 26th. Before Starship is technically ready for that milestone, however, one more test must be completed.

SpaceX has already successfully performed two static fire tests with a Raptor engine (likely SN18) installed on Starship SN4 on May 5th and 7th but the company has decided to replace that particular engine for unknown reasons. Raptor SN18 was removed from SN4 the morning after its (presumably) successful second static fire test, a move that is believed to have been made to avoid losing an engine in the event that a more ambitious cryogenic pressure test destroyed Starship.

As it turned out, that caution was unnecessary and Starship SN4 passed said pressure test with flying colors, reaching a planned maximum pressure of 7.5 bar (110 psi) – technically enough to qualify the rocket’s structure for (uncrewed) orbital launches.

For whatever reason, though, SpaceX has decided to replace Raptor SN18 with Raptor SN20, another of three engines currently on site at SpaceX’s South Texas rocket build and test facilities. That engine swap means that another Starship/Raptor static fire test is now needed to ensure that the new engine has been installed correctly and that both it and Starship are functioning as intended. As of now, SpaceX has scheduled that third static fire as early as Monday, May 11th, with a test window open from 9am to 9pm CDT (UTC-5).

If that static fire and include wet dress rehearsal (WDR) is successful, Starship will technically be cleared for flight. The only obvious missing piece is an attitude control system (ACS). Starhopper, for example, used cold nitrogen gas thrusters quite literally taken off of flight-proven Falcon boosters. It remains to be seen if SpaceX will take the same approach with Starship SN4 or if a different kind of ACS thruster is already installed on the rocket and hidden in plain sight. For now, it looks like we won’t have to wait long at all to find out.

Investor's Corner

Tesla analyst says this common earnings narrative is losing importance

“Numbers are going down next year, but that’s ok because it’s all about autonomy.”

A Tesla (NASDAQ: TSLA) analyst is doubling down on the idea that one common earnings narrative is losing importance as the company continues to work toward new technologies and projects.

This week, Tesla will report earnings for the third quarter, and one thing people always pay attention to is deliveries. Although Tesla reveals its deliveries for the quarter well before it reports earnings, many investors will look for commentary regarding the company’s strategy for responding to the loss of the $7,500 tax credit.

Tesla has made a few moves already, including a lease deal that takes a substantial amount of money off, launching new Standard models, and cutting up to 23 percent off of lease pricing.

Tesla makes crazy move to spur short-term demand in the U.S.

However, analysts are looking at the company in a different light.

Aligning with the narrative that Tesla is not just a car company and has many different projects, Gene Munster of Deepwater Asset Management believes many investors need to look at another part of the business.

Munster said the delivery figures for Q3, which landed at 497,099, the highest in company history, were padded by customers rushing to showrooms to take advantage of the expiring tax credit.

He believes that deliveries will be more realistic in subsequent quarters, but investors should not worry because the focus on Tesla is not going to be on how many cars it hands over to customers:

“Numbers are going down next year, but that’s ok because it’s all about autonomy.”

Tesla has been working nonstop to roll out a dedicated Robotaxi platform in various cities across the United States, and has already launched in two states: Texas and California.

It has also received regulatory approvals to test driverless Robotaxis in Arizona and Nevada, while seeking permissions in Florida and other states, according to the company’s online job postings.

Munster continued:

“Most people are hyper-focused on the Robotaxi opportunity and not focused as much on FSD.”

While Robotaxi is incredibly important, Tesla’s Full Self-Driving (Supervised) suite is also extremely crucial moving forward, as it sets the stage for the company to roll out a formidable self-driving service.

Tesla rolled out its newest FSD software to more owners last night, and as it expands, the company is gaining valuable data to refine its performance.

Earnings will be reported tomorrow at market close.

Tesla rolled out a new feature with FSD v14 to fix a major complaint

One of the most crucial cameras for FSD operation is located at the top of the windshield, and some owners have complained about condensation or other debris accumulating here, which impacts FSD’s availability during drives.

Tesla rolled out a new feature with Full Self-Driving (Supervised) v14.1.3 in an effort to fix a major complaint from owners.

Tesla’s approach to self-driving is significantly different than other companies as it only relies on cameras for operation. Tesla Vision was launched several years ago and completely axed any reliance the suite had on sensors, as CEO Elon Musk’s strategy was unorthodox and went against the grain.

However, it has proven to be effective, as Tesla still operates the most refined semi-autonomous driving suite in the United States.

There are some drawbacks, though, and one of them has to do with the obvious: cameras get dirty and need to be cleaned somewhat regularly.

One of the most crucial cameras for FSD operation is located at the top of the windshield, and some owners have complained about condensation or other debris accumulating here, which impacts FSD’s availability during drives:

Tesla has been working to confront this issue, and in classic fashion, it used a software update to work on resolving it.

With the rollout of Full Self-Driving v14.1.3 and Software Version 2025.32.8.15, Tesla added a new feature that aims to clean the front camera efficiently without relying on the owner to do it manually.

Tesla Full Self-Driving’s new version officially gets a wider rollout

In its release notes for the suite, it said:

“Added automatic narrow field washing to provide rapid and efficient front camera self-cleaning, and optimize aerodynamics wash at higher vehicle speed.”

If the camera starts to have some issues with visibility, the car will automatically clean the front windshield camera to avoid any issues:

This new addition is a small but mighty change considering all things. It is a necessary process to keep things operational and avoid any disruptions in FSD performance. It is also a testament to how much better Tesla vehicles can get with a simple software update.

Tesla’s newest Full Self-Driving version is officially rolling out wider to customers outside of the Early Access Program (EAP), in preparation for a total launch of the new v14 suite.

Over the past several weeks, Tesla has been working to refine its new v14 Full Self-Driving (Supervised) in an effort to have it ready for the entire fleet of vehicles in the United States. We are lucky enough to be in the EAP, so we’ve been able to test new features and rollouts first-hand.

So far, v14 has introduced a handful of new features and improvements, but the first versions needed refinement before Tesla made an effort to expand the population. It had issues with a brake stutter, but this has been mostly resolved.

Additionally, the rollout of the new Mad Max Speed Profile has gathered some attention.

Now that Tesla has started rolling out v14.1.3 yesterday to EAP members, the company ultimately decided that it was time to expand the software to more vehicles, as many owners are reporting that they’re receiving it:

Additionally, the suite has started to expand to Model S and Model X vehicles, so this rollout is not exclusive to Model 3 and Model Y:

The only issue with this rollout is that it still appears to be missing the Cybertruck, which Tesla was transparent about earlier this month. Although the company planned to release v14 to Cybertrucks by the end of the month, there has been no hint that this is going to happen.

This is already the third iteration of v14 in the past two weeks, indicating that Tesla is truly addressing the shortcomings of past versions and rolling out updates as quickly as possible.
