SpaceX’s first orbital-class Starship prototype has survived the first of several expected Raptor tests, kicking off an engine test campaign that could mark a number of new milestones.

With just 20 minutes left in a seven-hour test window, Starship prototype S20 (Ship 20) appeared to either unsuccessfully attempt its first Raptor static fire test or complete its first intentional Raptor preburner test around 11:40 pm CDT (UTC-5) on Monday, October 18th. Rather than a violent jolt and roar kicking up a cloud of dust, Ship 20 came to life with a (relatively) gentle fireball that lasted for several seconds.

In pursuit of maximum efficiency, Starship’s Raptors require two separate closed-cycle gas generators known as preburners to – as the name suggests – turn its cryogenic (very cold) liquid oxygen and methane propellant into a hot gas mixture that the engine re-ignites to produce thrust. A preburner test, if that’s what Starship S20 completed on Monday night, thus involves activating only the first half of that equation, rapidly producing a giant cloud of flammable gas without actually igniting to produce meaningful thrust.

Preburner tests have become increasingly rare as SpaceX’s sea-level Raptor design matured over the course of tens of thousands of seconds of ground testing and, later, thousands of seconds of ground and flight testing on Starship prototypes. Starship S20 had two engines during its first test. One Raptor was the sea-level optimized variant SpaceX has built dozens of and fired for 30,000+ seconds on the ground. The other, however, was a vacuum-optimized Raptor with a much larger nozzle – the first of its kind to participate in any kind of test while installed on a Starship prototype.

It’s possible that Raptor Vacuum (RVac) engines have even more design tweaks outside of their larger expansion nozzles. Regardless, SpaceX has only built and tested around 10 RVac prototypes over the last year, making it a less mature engine than its sea-level cousins. That could explain why SpaceX appears to have chosen to perform a preburner test first instead of jumping straight into a wet dress rehearsal and static fire. That also means that October 18th’s test was likely the first time a Raptor Vacuum engine has (partially) ignited while installed on a Starship.

The above view from a uniquely situated LabPadre camera all but guarantees that Starship S20’s first engine test was a Raptor Vacuum preburner test and doesn’t offer any strong evidence that it was a two-engine test. Ship 20 still has a number of crucial tests ahead of it before SpaceX can even begin to consider it (or its general design) qualified for flight. That includes multiple static fires, including the first side-by-side static fire of two Raptor variants (RVac and Raptor Center), the first simultaneous static fire of more than three engines, and the first Starship static fire with a full six engines installed.

Ship 20’s preburner test is SpaceX’s first Starbase Raptor test since the first Super Heavy booster static fire in mid-July, almost exactly three months ago.

With any luck, S20’s first preburner test has opened the door for an inaugural static fire of one or both installed engines later this week. However, during that preburner test, the giant fireball Raptor Vacuum emitted appeared to ignite several pieces of pad hardware. SpaceX took advantage of one of at least two Boston Dynamics Spot robots on-site to physically walk a camera up to the active pad and inspect several secondary fires. Ultimately, SpaceX appears to have successfully safed Starship with no damage to the vehicle itself, but odds are good that the sources of those secondary fires will need to be fixed and any pad damage repaired before Ship 20 proceeds into static fire testing. SpaceX has two more 5pm-12am test windows scheduled on October 19th and 20th.

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

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.

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.
