After a relatively relaxed period of production and testing, SpaceX’s South Texas Starship factory is practically overflowing with new and flight-proven ships as the company prepares for the rocket’s next major tests.

Even before the one-off Starship Mk1 prototype failed a pressure test late last year, SpaceX was in the process of upgrading its Boca Chica production facilities and refining the ship’s design and manufacturing processes. Starship SN1, the first prototype built as part of that upgrade, rolled to the launch pad on February 25th, 2020, followed by Starship SN2 (turned into a test tank) just a week or so later. Starship SN3 and SN4 would both follow in early and late April, ultimately ending with the latter prototype’s spectacularly violent demise in late May.

Over the remaining three or so months, the pace of testing has slowed a bit as SpaceX’s Starship development program enters the full-scale flight testing phase. Starship SN5 began testing on July 1st, followed by SN6 around six weeks later. Both prototypes successfully hopped just 30 days apart. Now, although SpaceX still plans to hop SN5 a second time and may hop SN6 twice, too, the Starship program’s focus has shifted to high-altitude, high-velocity flight tests and the adoption of a new steel alloy.

Presumably in anticipation of a learning curve as that new steel alloy begins to be tested at full-scale for the first times, SpaceX is churning out Starship prototypes at an unprecedented pace. Intriguingly, that production ramp is hinged upon the assumption that a 304L-class steel alloy (compared to the 301 stainless steel used to build SN1 through SN6) will be as good or better than 301 steel in every significant way.

Currently, that assumption isn’t entirely baseless but is still built upon the success of Starship SN7, SpaceX’s first 304L test tank. SpaceX never confirmed its results but it’s believed that that test tank – more of a material demonstrator than an actual structural Starship prototype – surpassed all previous pressure records before it burst in June.

Given that SN7 performed quite well, it’s at least a bit less surprising that SpaceX is hinging months of work and at least four full-scale Starship prototypes on an otherwise unproven steel alloy. The next big test for 304L Starships will be a second test tank known as SN7.1. Rolled to the test site on September 7th, essentially as soon as Starship SN6 was safed and returned to the factory after its hop debut, SN7.1 is significantly more complex than its sibling and will test a ~304L Raptor mount (thrust puck) and skirt section. The forces and general conditions those new parts will be subjected to are substantially different than most of what SN7 was subjected to, meaning that there is a chance that 304L steel is less optimal in different scenarios.

With any luck, SN7.1’s test campaign – scheduled to begin as early as 9pm CDT (UTC-5), September 10th (today) – will be a flawless success, proving that SpaceX’s new steel alloy is universally superior to 301 for Starship-related applications. If that’s the case, Starship SN8 – the first full new-alloy prototype – will likely be fully outfitted with a nosecone and header tanks before beginning acceptance testing.

Eventually, if SN7.1 aces its tests and SN8 performs well during preflight preparations, Starship SN8 could become the first prototype to launch with a full nose, header tanks, and flaps, as well as the first to fly with three Raptor engines. If Starship SN8 fails for any reason or is damaged during testing, though, it appears that SpaceX will have no shortage of ships built out of the same new steel alloy to choose from.

In just the last ten days, labeled parts and rings for Starships SN9, SN10, and SN11 have all been spotted, implying that SpaceX is concurrently building at least four new Starships. Notably, both Starships SN9 and SN11 already appear to have some of the studs needed for heat shield tile installation affixed to sections of their steel hulls. Based on the sheer number of steel ring stacks spotted over the last week, it’s also safe to assume that SN9’s tank section (and possibly SN10’s, too) is largely prefabricated.

SN10’s forward dome was sleeved on September 8th. (NASASpaceflight – bocachicagal)
The first labeled Starship SN11 rings were spotted on September 9th. (NASASpaceflight – bocachicagal)
Two reinforced five-ring stacks will likely support nosecones on two new Starships. (NASASpaceflight – bocachicagal)

Assuming two of the in-work nosecones are ultimately meant for flight, SpaceX may already have enough hardware on hand to fully assemble two Starships (presumably SN8 and SN9) – including nosecones, header tanks, nose rings, and flaps. It’s safe to say that if SN7.1 achieves its goals, preparations for the first triple Raptor hop, 20 km (~12 mi) test flight, and skydiver-style landing attempt could come together incredibly quickly.

SpaceX’s Starship V3 is almost ready and it will change space travel forever

SpaceX is targeting April for the debut test launch of Starship V3 “Version 3”

Published

SpaceX is closing in on one of the most anticipated rocket launches in history, as the company readies for a planned April test launch and debut of its next-gen Starship V3 “Version 3”.

The latest iteration of Starship V3 has a slightly taller Super Heavy booster and Starship upper stage than their predecessors, and produce stronger, more efficient thrust using SpaceX’s upgraded Raptor 3 engines. V3 also features increased propellant capacity, targeting a total payload capacity of over 100 tons to low Earth orbit, compared to around 35 tons for its predecessor. With Musk’s lifelong aspiration to colonize Mars one day, the increased payload capacity matters enormously, because Mars missions require moving massive amounts of cargo, fuel, and eventually, people. But the most critical upgrade may be orbital refueling. SpaceX’s entire deep space architecture depends on moving large amounts of propellant in space, and having orbital refueling capabilities turn Starship from just a rocket into a true transport system. Without it, neither the Moon nor Mars is reachable at scale.

A fully reusable Starship and Super Heavy, SpaceX aims to drive marginal launch costs down and at a tenfold reduction compared to current market leaders. To put that in perspective, getting a kilogram of cargo to orbit today costs thousands of dollars. Bring that number down far enough and space stops being an exclusive domain. That price point unlocks mass deployment of satellite constellations, large-scale science payloads, and affordable human transport beyond Earth orbit. It also means the Moon stops being a destination we visit and starts being one we inhabit.

Elon Musk pivots SpaceX plans to Moon base before Mars

NASA expects Starship to take off for the Moon’s South Pole in 2028, with the ultimate goal of establishing a permanently crewed science station there. A successful V3 flight this spring keeps that timeline alive.  As for Mars, Musk has shifted focus toward building a self-sustaining city on the Moon first, arguing that the Moon can be reached every 10 days versus Mars’s 26-month alignment window. Mars remains the horizon, but the Moon is the proving ground.

Elon Musk hasn’t been shy with hyping the upcoming Starship V3 launch. In a social media post on Wednesday, he confirmed the first V3 flight is getting closer to launch. SpaceX also announced its initial activation campaign for V3 and Starbase Pad 2 was complete, wrapping up several days of cryogenic fuel testing on a V3 vehicle for the first time. The countdown is on. April can’t come soon enough.

Tesla is rolling out a new and long-awaited feature to the Cybertruck all-electric pickup, and it is a safety addition geared toward pedestrian and cyclist safety, as well as accidents with other vehicles.

Tesla has announced the rollout of its innovative anti-dooring protection feature to the Cybertruck via the 2026.8 software update.

This safety enhancement uses the vehicle’s existing cameras to detect approaching cyclists, pedestrians, or vehicles in the blind spot while parked. Upon attempting to open a door, if a hazard is detected, the system activates: the blind spot indicator light flashes, an audible chime sounds, and the door will not open on the initial button press.

Drivers must wait briefly and press the button again to override, providing crucial seconds to avoid an accident.

The feature, also known as Blind Spot Warning While Parked, comes standard on every new Model 3 and Model Y, and is now extending to the Cybertruck. Leveraging Tesla’s vision-based system without requiring new hardware, it represents a cost-effective software solution that builds on community suggestions dating back to 2018.

This technology addresses the persistent danger of “dooring,” where a driver opens a car door into the path of a passing cyclist or pedestrian.

Tesla implemented this little-known feature to make its cars even safer

Dooring incidents are alarmingly common in urban environments.

According to Chicago data, in 2011 alone, there were 344 reported dooring crashes, accounting for approximately 20 percent of all bicycle crashes in the city, nearly one incident per day.

While numbers have fluctuated (dropping to 11 percent in 2014 before rising again), dooring consistently represents 10-20 percent of bike-related crashes in major cities.

A national analysis of emergency department data estimates over 17,000 dooring-related injuries treated in the U.S. over a decade, with many involving fractures, contusions, and head trauma, particularly affecting upper extremities.

By automatically intervening, Tesla’s system not only protects vulnerable road users but also safeguards its owners from potential liability and enhances overall road safety.

As cities promote cycling for sustainable transport, features like this demonstrate how advanced driver assistance and camera systems can evolve beyond highway driving to everyday urban scenarios.

Enthusiastic responses on social media highlight appreciation for the proactive safety measure, with some calling for broader rollout to older models where hardware permits. Tesla continues to push the boundaries of vehicle safety through over-the-air updates, making its fleet smarter and safer over time.

Tesla Roadster is ‘sorcery and magic’ and might be worth the wait, Uber founder says

Perhaps the wait will be worth it, especially according to Uber founder Travis Kalanick, who recently teased the Roadster’s potential capabilities based on what he has heard from internal Tesla sources.

Tesla is planning to unveil the Roadster in late April after years of waiting. But the wait might be worth it, according to Travis Kalanick, the founder of Uber, who recently shed some light on his expectations for the all-electric supercar.

We all know the Roadster is supposed to have some serious capability. CEO Elon Musk has said on numerous occasions that the Roadster will be unlike anything else ever produced. It might go from 0-60 MPH in about a second, it might hover, it might have SpaceX cold gas thrusters.

However, the constant delays in the Roadster program and its unveiling event continue to send Tesla fans into confusion because they’re just not sure when, or if, they’ll ever see the finished product.

Perhaps the wait will be worth it, especially according to Uber founder Travis Kalanick, who recently teased the Roadster’s potential capabilities based on what he has heard from internal Tesla sources.

Kalanick said on X:

Musk has said this vehicle is not going to be geared for safety, and that, “If safety is your number one goal, do not buy the Roadster.”

There has been so much hype regarding the Roadster that it is hard to believe the company could not come through on some kind of crazy features for the vehicle.

Elon Musk just dropped a huge detail on the Tesla Roadster

However, the latest delay that Tesla put on the unveiling event is definitely eye-opening, especially considering it is the latest in a series of pushbacks the company has put on the vehicle for the past several years.

Tesla has made several jumps in the Roadster project over the past few months, as it has ramped up hiring for the vehicle and also applied for a patent for a new seat design.

The car has been a back-burner project for Tesla, as it has been focusing primarily on autonomy and the rollout of Robotaxi and Cybercab. Additionally, its other vehicle projects, like the Model 3 and Model Y refreshes, took precedence.

Tesla still plans to unveil the Roadster next month, so we can hope the company can stick to this timeframe.
