SpaceX’s upgraded Super Heavy booster sails through first major test

Published

on

SpaceX’s first upgraded 33-engine Super Heavy booster appears to have passed a crucial test with surprising ease, boding well for a smooth qualification process.

Attempting that test so early on did not appear to be SpaceX’s initial plan. Instead, shortly before Super Heavy Booster 4’s third and likely final removal from Starbase’s ‘orbital launch mount’ (OLM) on March 24th, SpaceX transported a massive structural test stand from a Starbase storage yard to the orbital launch site (OLS), where technicians have focused on modifying nearby ground systems to support apparent structural testing of Super Heavy Booster 7. As of March 31st, all available evidence suggested that SpaceX was preparing that stand to verify Booster 7’s mechanical strength and simulate the major stresses it might experience before investing a significant amount of time and resources in qualification testing.

However, SpaceX appeared to change its plans at the last minute.

Instead of starting with structural testing, after a brief two-day pause, SpaceX rolled Super Heavy B7 into place and craned the giant booster onto the orbital launch mount on April 2nd. On April 3rd, the launch mount’s “quick disconnect” device connected Super Heavy to the pad’s ground systems. On April 4th, just two days after its installation on the OLM, Super Heavy B7 kicked off the first in a series of qualification tests that will determine when or if the booster ultimately supports Starship’s first orbital launch attempt.

If testing goes perfectly, SpaceX CEO Elon Musk recently stated that Starship and Super Heavy – likely Ship 24 and Booster 7 – could be ready for an inaugural orbital launch attempt as early as May 2022. SpaceX appears to have leaped headfirst into Super Heavy Booster 7 qualification testing in a move that significantly increases the likelihood of meeting that extremely ambitious schedule. Normally, with a first-of-its-kind prototype debuting multiple significant design changes, SpaceX would start slow, possibly beginning with a basic pneumatic proof test to verify structural integrity at flight pressures – about 6.5-8.5 bar (95-125 psi) – with benign nitrogen gas before calling it a day.

With Booster 7, SpaceX likely still performed a quick pneumatic proof but then immediately proceeded into a full-scale cryogenic proof test. With Super Heavy B4, for example, SpaceX performed several increasingly ambitious cryogenic proof tests, filling the booster more and more each attempt but never actually topping it off. On Booster 7’s very first day of testing and first cryogenic proof attempt, SpaceX fully loaded the upgraded Super Heavy with a cryogenic fluid (likely liquid nitrogen) in just two hours – all with no significant unplanned holds (pauses).

In those two hours, SpaceX likely loaded Super Heavy B7’s liquid methane (LCH4) and oxygen (LOx) tanks with roughly 3400 metric tons (~7.5M lb) of liquid nitrogen (LN2) – not far off what Super Heavy would actually weigh at liftoff. At the peak of the test, Booster 7 was almost entirely covered in a thin layer of ice produced as the cryogenic liquid inside its tanks froze water vapor in the humid South Texas air onto its skin – an effect that effectively turns uninsulated cryogenic rockets into giant fill gauges. On top of running into no apparent issues, Super Heavy B7’s first cryogenic proof is also the first time any Super Heavy prototype has been fully filled during testing – an important milestone for any rocket prototype, let alone the largest rocket booster ever built.

Completing a full cryogenic proof test on its first try makes Booster 7 fairly unique among all Starship prototypes – not just Super Heavies. The contrast with Booster 4, which barely completed a handful of partial cryogenic proof tests in more than half a year spent at Starbase’s orbital launch site, is also extremely encouraging, suggesting that Booster 7 won’t be sitting inactive for months at a time.

Still, cryogenic proofing is just one of several important tests Booster 7 needs to complete. Even if the first test was nearly perfect and SpaceX doesn’t attempt one or several more cryoproofs with higher tank pressures or other tweaked variables, Super Heavy B7 needs to complete wet dress rehearsal testing (WDR) with flammable LCH4/LOx propellant and demonstrate autogenous pressurization (using heated propellant gas to pressure its tanks). At some point, SpaceX will also need to install a full 33 Raptor V2 engines on the booster and seal off the whole engine section and each Raptor with a heat shield.

Depending on how many Raptor V2 engines are available, SpaceX could begin static fire testing with just a few engines installed and shielded and then install the rest of the engines and heat shield later on. On the other hand, performing static fires without a full heat shield could risk damaging unprotected cabling or other subsystems, in which case wet dress rehearsal testing would likely follow immediately after cryoproofing and before engine or shield installation. After being skipped over, the structural test stand may also factor into Booster 7 qualification sometime before engine installation.

All told, plenty of uncertainty remains, but Super Heavy B7’s auspicious start suggests that the Booster 4 experience is far from a template and that SpaceX is much less interested in wasting time this time around.

Tesla confirms date when new Cybertruck trim will go up in price

Tesla has officially revealed that this price will only be available until February 28, as the company has placed a banner atop the Design Configurator on its website reflecting this.

Tesla has confirmed the date when its newest Cybertruck trim level will increase in price, after CEO Elon Musk noted that the All-Wheel-Drive configuration of the all-electric pickup would only be priced at its near-bargain level for ten days.

Last week, Tesla launched the All-Wheel-Drive configuration of the Cybertruck. Priced at $59,990, the Cybertruck featured many excellent features and has seemingly brought some demand to the pickup, which has been underwhelming in terms of sales figures over the past couple of years.

Tesla launches new Cybertruck trim with more features than ever for a low price

When Tesla launched it, many fans and current owners mulled the possibility of ordering it. However,  Musk came out and said just hours after launching the pickup that Tesla would only keep it at the $59,990 price level for ten days.

What it would be priced at subsequently was totally dependent on how much demand Tesla felt for the new trim level, which is labeled as a “Dual Motor All-Wheel-Drive” configuration.

Tesla has officially revealed that this price will only be available until February 28, as the company has placed a banner atop the Design Configurator on its website reflecting this:

Many fans and owners have criticized Tesla’s decision to unveil a trim this way, and then price it at something, only to change that price a few days later based on how well it sells.

It seems the most ideal increase in price would be somewhere between $5,000 and $10,000, but it truly depends on how many orders Tesla sees for this new trim level. The next step up in configuration is the Premium All-Wheel-Drive, which is priced at $79,990.

The difference between the Dual Motor AWD Cybertruck and the Premium AWD configuration comes down to towing, interior quality, and general features. The base package is only capable of towing up to 7,500 pounds, while the Premium can handle 11,000 pounds. Additionally, the seats in the Premium build are Vegan Leather, while the base trim gets the textile seats.

It also has only 7 speakers compared to the 15 that the Premium trim has. Additionally, the base model does not have an adjustable ride height, although it does have a coil spring with an adaptive damping suspension package.

Tesla set to activate long-awaited Cybertruck feature

Tesla will officially activate the Active Noise Cancellation (ANC) feature on Cybertruck soon, as the company has officially added the feature to its list of features by trim on its website.

Tesla is set to activate a long-awaited Cybertruck feature, and no matter when you bought your all-electric pickup, it has the hardware capable of achieving what it is designed to do.

Tesla simply has to flip the switch, and it plans to do so in the near future.

Tesla will officially activate the Active Noise Cancellation (ANC) feature on Cybertruck soon, according to Not a Tesla App, as the company has officially added the feature to its list of features by trim on its website.

Tesla rolls out Active Road Noise Reduction for new Model S and Model X

The ANC feature suddenly appeared on the spec sheet for the Premium All-Wheel-Drive and Cyberbeast trims, which are the two configurations that have been delivered since November 2023.

However, those trims have both had the ANC disabled, and although they are found in the Model S and Model X, and are active in those vehicles, Tesla is planning to activate them.

In Tesla’s Service Toolbox, it wrote:

ANC software is not enabled on Cybertruck even though the hardware is installed.”

Tesla has utilized an ANC system in the Model S and Model X since 2021. The system uses microphones embedded in the front seat headrests to detect low-frequency road noise entering the cabin. It then generates anti-noise through phase-inverted sound waves to cancel out or reduce that noise, creating quieter zones, particularly around the vehicle’s front occupants.

The Model S and Model X utilize six microphones to achieve this noise cancellation, while the Cybertruck has just four.

Tesla Cybertruck Dual Motor AWD estimated delivery slips to early fall 2026

As previously mentioned, this will be activated through a software update, as the hardware is already available within Cybertruck and can simply be activated at Tesla’s leisure.

The delays in activating the system are likely due to Tesla Cybertruck’s unique design, which is unlike anything before. In the Model S and Model X, Tesla did not have to do too much, but the Cybertruck has heavier all-terrain tires and potentially issues from the aluminum castings that make up the vehicle’s chassis, which are probably presenting some challenges.

Unfortunately, this feature will not be available on the new Dual Motor All-Wheel-Drive configuration, which was released last week.

Tesla Model S and X customization options begin to thin as their closure nears

Tesla’s Online Design Studio for both vehicles now shows the first color option to be listed as “Sold Out,” as Lunar Silver is officially no longer available for the Model S or Model X. This color is exclusive to these cars and not available on the Model S or Model X.

Tesla Model S and Model X customization options are beginning to thin for the first time as the closure of the two “sentimental” vehicles nears.

We are officially seeing the first options disappear as Tesla begins to work toward ending production of the two cars and the options that are available to those vehicles specifically.

Tesla’s Online Design Studio for both vehicles now shows the first color option to be listed as “Sold Out,” as Lunar Silver is officially no longer available for the Model S or Model X. This color is exclusive to these cars and not available on the Model S or Model X.

Tesla is making way for the Optimus humanoid robot project at the Fremont Factory, where the Model S and Model X are produced. The two cars are low-volume models and do not contribute more than a few percent to Tesla’s yearly delivery figures.

With CEO Elon Musk confirming that the Model S and Model X would officially be phased out at the end of the quarter, some of the options are being thinned out.

This is an expected move considering Tesla’s plans for the two vehicles, as it will make for an easier process of transitioning that portion of the Fremont plant to cater to Optimus manufacturing. Additionally, this is likely one of the least popular colors, and Tesla is choosing to only keep around what it is seeing routine demand for.

During the Q4 Earnings Call in January, Musk confirmed the end of the Model S and Model X:

“It is time to bring the Model S and Model X programs to an end with an honorable discharge. It is time to bring the S/X programs to an end. It’s part of our overall shift to an autonomous future.”

Fremont will now build one million Optimus units per year as production is ramped.
