SpaceX Starship test plans solidify after bad weather delays hop

Published

on

Around the same time SpaceX was preparing for its 100th Falcon rocket launch, bad Texas weather forced the company to abort its second Starship hop test of the month.

Since that abort, SpaceX’s near-term Starship test plans have begun to solidify, offering a clearer picture of what to expect over the next week or two. Pending better weather at its Boca Chica, Texas test facilities, Starship serial number 6 (SN6) is still first in line and has been preparing for its hop debut ever since the prototype completed a Raptor engine static fire test on August 23rd.

Measuring approximately 30m (~100 ft) tall, SN6 is a full-scale Starship tank and engine section – the bottom ~60% and business end of the reusable orbital spacecraft. Of course, SpaceX has a ways to go before Starship is actually ready for its first orbital test flight, let alone reuse after such a test flight, but the company did take its biggest step yet towards that lofty ambitions with Starship SN5’s successful August 4th hop debut.

Effectively twins, Starship SN5 and SN6 have since been expected to take turns completing “several” hops to improve SpaceX’s familiarity with Starship launch operations and work towards a smooth procedure that can be completed multiple times per day. With SN6 now scheduled to hop no earlier than 8am CDT (UTC-5), September 3rd, 29 days after SN5’s debut, SpaceX still has its work cut out for it.

Nevertheless, SN5’s 150m (~500 ft) hop was the first flight of any kind for a full-scale Starship prototype, as well as the first use of an entirely new landing leg design and Raptor’s first flight in almost a year. In the history of rocket development, there is no precedent for launching and landing a prototype rocket and then repeating the same test with an entirely new prototype less than a month later.

Additionally, most of the 29 days since SN5’s first hop have been spent preparing Starship SN6 for a crucial “cryo proof” qualification test. Had that cryo proof been completed before SN5’s hop debut, SN6 could have been ready to fly as few as ~10 days later. That still leaves SpaceX a long ways away from multiple Starship hops per day but does offer encouragement that flight-proven Starship SN5 could be ready for its second hop not long after the pad is clear.

However, it appears that SpaceX instead plans to follow up SN6’s hop debut with a new ‘test tank’ meant to demonstrate an upgraded Starship “thrust puck” built out of a different steel alloy. Known as Starship SN7.1, the test will follow on the heels of a more traditional tank (SN7) that completed a record-breaking pressure test in June 2020 and proved that Starship would likely be better off with a different steel alloy.

While SN7 was a basic test tank (two domes and a few steel rings), SN7.1 adds a skirt section at its base and replaces the aft dome with a thrust dome. Likely built entirely out of a steel alloy closer to 304L than the 301 SpaceX has used for all prior Starship prototypes, that thrust dome features a new ‘thrust puck’ – the structural element Raptor engines attach to and transmit their thrust through.

Unlike past single tank tests, SN7.1 will be put through something more like a full prototype’s cryo pressure test. SN7.1 will be installed on a launch mount, allowing its skirt clamps to firmly secure the prototype to the stand, itself secured to a concrete slab on the ground. That launch mount also allows SpaceX to install a hydraulic ram designed to mechanically simulate the thrust of 1-3 Raptor engines without the risk involved in an actual static fire. SN7.1 is scheduled to begin testing no earlier than (NET) 8 am CDT (UTC-5), September 6th – just three days after SN6’s next planned hop attempt.

Tesla Full Self-Driving v14.2 – Full Review, the Good and the Bad

Published

on

Credit: Teslarati

Tesla rolled out Full Self-Driving version 14.2 yesterday to members of the Early Access Program (EAP). Expectations were high, and Tesla surely delivered.

With the rollout of Tesla FSD v14.2, there were major benchmarks for improvement from the v14.1 suite, which spanned across seven improvements. Our final experience with v14.1 was with v14.1.7, and to be honest, things were good, but it felt like there were a handful of regressions from previous iterations.

While there were improvements in brake stabbing and hesitation, we did experience a few small interventions related to navigation and just overall performance. It was nothing major; there were no critical takeovers that required any major publicity, as they were more or less subjective things that I was not particularly comfortable with. Other drivers might have been more relaxed.

With v14.2 hitting our cars yesterday, there were a handful of things we truly noticed in terms of improvement, most notably the lack of brake stabbing and hesitation, a major complaint with v14.1.x.

However, in a 62-minute drive that was fully recorded, there were a lot of positives, and only one true complaint, which was something we haven’t had issues with in the past.

The Good

Lack of Brake Stabbing and Hesitation

Perhaps the most notable and publicized issue with v14.1.x was the presence of brake stabbing and hesitation. Arriving at intersections was particularly nerve-racking on the previous version simply because of this. At four-way stops, the car would not be assertive enough to take its turn, especially when other vehicles at the same intersection would inch forward or start to move.

This was a major problem.

However, there were no instances of this yesterday on our lengthy drive. It was much more assertive when arriving at these types of scenarios, but was also more patient when FSD knew it was not the car’s turn to proceed.

This improvement was the most noticeable throughout the drive, along with fixes in overall smoothness.

Speed Profiles Seem to Be More Reasonable

There were a handful of FSD v14 users who felt as if the loss of a Max Speed setting was a negative. However, these complaints will, in our opinion, begin to subside, especially as things have seemed to be refined quite nicely with v14.2.

Freeway driving is where this is especially noticeable. If it’s traveling too slow, just switch to a faster profile. If it’s too fast, switch to a slower profile. However, the speeds seem to be much more defined with each Speed Profile, which is something that I really find to be a huge advantage. Previously, you could tell the difference in speeds, but not in driving styles. At times, Standard felt a lot like Hurry. Now, you can clearly tell the difference between the two.

It seems as if Tesla made a goal that drivers should be able to tell which Speed Profile is active if it was not shown on the screen. With v14.1.x, this was not necessarily something that could be done. With v14.2, if someone tested me on which Speed Profile was being used, I’m fairly certain I could pick each one.

Better Overall Operation

I felt, at times, especially with v14.1.7, there were some jerky movements. Nothing that was super alarming, but there were times when things just felt a little more finicky than others.

v14.2 feels much smoother overall, with really great decision-making, lane changes that feel second nature, and a great speed of travel. It was a very comfortable ride.

The Bad

Parking

It feels as if there was a slight regression in parking quality, as both times v14.2 pulled into parking spots, I would have felt compelled to adjust manually if I were staying at my destinations. For the sake of testing, at my first destination, I arrived, allowed the car to park, and then left. At the tail-end of testing, I walked inside the store that FSD v14.2 drove me to, so I had to adjust the parking manually.

This was pretty disappointing. Apart from parking at Superchargers, which is always flawless, parking performance is something that needs some attention. The release notes for v14.2. state that parking spot selection and parking quality will improve with future versions.

However, this was truly my only complaint about v14.2.

SpaceX has issued an initial statement about Starship Booster 18’s anomaly early Friday. The incident unfolded during gas-system pressure testing at the company’s Massey facility in Starbase, Texas. 

SpaceX’s initial comment

As per SpaceX in a post on its official account on social media platform X, Booster 18 was undergoing gas system pressure tests when the anomaly happened. Despite the nature of the incident, the company emphasized that no propellant was loaded, no engines were installed, and personnel were kept at a safe distance from the booster, resulting in zero injuries.

“Booster 18 suffered an anomaly during gas system pressure testing that we were conducting in advance of structural proof testing. No propellant was on the vehicle, and engines were not yet installed. The teams need time to investigate before we are confident of the cause. No one was injured as we maintain a safe distance for personnel during this type of testing. The site remains clear and we are working plans to safely reenter the site,” SpaceX wrote in its post on X. 

Incident and aftermath

Livestream footage from LabPadre showed Booster 18’s lower half crumpling around the liquid oxygen tank area at approximately 4:04 a.m. CT. Subsequent images posted by on-site observers revealed extensive deformation across the booster’s lower structure. Needless to say, spaceflight observers have noted that Booster 18 would likely be a complete loss due to its anomaly.

Booster 18 had rolled out only a day earlier and was one of the first vehicles in the Starship V3 program. The V3 series incorporates structural reinforcements and reliability upgrades intended to prepare Starship for rapid-reuse testing and eventual tower-catch operations. Elon Musk has been optimistic about Starship V3, previously noting on X that the spacecraft might be able to complete initial missions to Mars.

Tesla (NASDAQ:TSLA) received fresh support from Piper Sandler this week after analysts toured the Fremont Factory and tested the company’s latest Full Self-Driving software. The firm reaffirmed its $500 price target, stating that FSD V14 delivered a notably smooth robotaxi demonstration and may already perform at levels comparable to, if not better than, average human drivers. 

The team also met with Tesla leaders for more than an hour to discuss autonomy, chip development, and upcoming deployment plans.

Analysts highlight autonomy progress

During more than 75 minutes of focused discussions, analysts reportedly focused on FSD v14’s updates. Piper Sandler’s team pointed to meaningful strides in perception, object handling, and overall ride smoothness during the robotaxi demo.

The visit also included discussions on updates to Tesla’s in-house chip initiatives, its Optimus program, and the growth of the company’s battery storage business. Analysts noted that Tesla continues refining cost structures and capital expenditure expectations, which are key elements in future margin recovery, as noted in a Yahoo Finance report. 

Analyst Alexander Potter noted that “we think FSD is a truly impressive product that is (probably) already better at driving than the average American.” This conclusion was strengthened by what he described as a “flawless robotaxi ride to the hotel.”

Street targets diverge on TSLA

While Piper Sandler stands by its $500 target, it is not the highest estimate on the Street. Wedbush, for one, has a $600 per share price target for TSLA stock.

Other institutions have also weighed in on TSLA stock as of late. HSBC reiterated a Reduce rating with a $131 target, citing a gap between earnings fundamentals and the company’s market value. By contrast, TD Cowen maintained a Buy rating and a $509 target, pointing to strong autonomous driving demonstrations in Austin and the pace of software-driven improvements. 

Stifel analysts also lifted their price target for Tesla to $508 per share over the company’s ongoing robotaxi and FSD programs.
