SpaceX preparing for third Starship ‘full stack’

SpaceX appears to be preparing Starship 20 and Super Heavy Booster 4 for their third ‘full stack’ demonstration after two seemingly successful tests in August 2021 and February 2022.

The first, completed in early August 2021, was mostly for show and saw SpaceX stack the unfinished prototypes with a giant crane – fighting the coastal winds throughout. After just a few hours stacked, Ship 20 was removed and returned to Starbase, where workers spent several more weeks (mostly) finishing the prototype. Booster 4 followed suit several weeks later and ultimately took another three months of work to reach some level of test readiness.

After Ship 20 and Booster 4 completed a series of tests in the last few months of 2021 and early 2022, the two were re-stacked in mid-February – once again for show. This time, the stacked Starship served as a backdrop for SpaceX CEO Elon Musk’s first official Starship presentation in more than two years. However, despite the fact that neither prototype was actually tested during the second stack, SpaceX did use the opportunity to partially debut Starbase’s ‘orbital launch integration tower’ and used that towers trio of giant arms to lift, stack, and stabilize Starship S20 on top of Super Heavy B4.

Ship 20 was ‘destacked’ with the tower’s arms just a few days after Musk’s event – an undeniably rapid and impressive achievement for the first real use of the ‘chopstick’ arms but still far from demonstrating that Ship 20, Booster 4, or the orbital launch site (OLS) are ready for orbital test flights. Since then, however, Starbase’s launch facilities have admittedly been almost as busy as they’ve ever been with Starship and Super Heavy cryoproof tests.

Ship 20 completed its first basic OLS cryogenic proof test or ‘cryoproof’ just two days after it was destacked. Additional Starship S20 cryoproofs followed on February 17th (the day after), February 22nd, and March 3rd. Super Heavy B4 completed its own cryoproofs on February 18th and March 1st, the latter of which may have actually been the fullest a Starship booster has ever been filled. All told, SpaceX completed no less than six major B4/S20 cryoproof tests in 15 days.

Crucially, all six cryoproofs were performed with Starbase’s nascent orbital tank farm, thoroughly testing its storage and distribution capabilities. Additionally, because SpaceX began liquid methane deliveries on February 13th, some of those tests – particularly with Ship 20 – may have even been proper wet dress rehearsals, meaning that SpaceX may have filled the rocket(s) with liquid methane (LCH4) and liquid oxygen (LOx) propellant to replicate preparations for a real launch.

At a minimum, Super Heavy Booster 4’s oxidizer tank was fully filled with liquid oxygen – and possibly pressurized with hot gaseous oxygen – during its March 1st cryoproof, while its fuel tank was filled about two-thirds of the way either with liquid nitrogen (LN2) or methane. Prior to its February and March tests, Booster 4 had already completed three cryoproofs – some also using LOx – in December 2021. Ship 20 had completed a cryoproof and four static fire tests.

All told, short of finally performing a full Super Heavy wet dress rehearsal and static fire at the orbital launch site, it’s not all that clear what more SpaceX can derive from additional individual cryoproof testing of Ship 20 or Booster 4. Several things do still need to be demonstrated, however. First, the OLS launch tower has yet to use its arms to remotely install a Super Heavy on the orbital launch mount. More importantly, SpaceX has yet to use the launch tower and its swinging ship umbilical arm to cryoproof or fuel a Starship while stacked on top of a Super Heavy. Finally, SpaceX has also yet to simultaneously perform a cryoproof or wet dress rehearsal test of a stacked Starship and Super Heavy, which will be necessary for orbital test flights.

One or several of those to-be-completed tests may be why SpaceX appears to have begun preparing to install Ship 20 on top of Booster 4 for the third time. On March 14th, Starship S20 was moved towards the launch tower and on March 15th, the ship was slotted between its ‘chopstick’ arms. Based on stack #2, the ship could be lifted at any point – day or night – and installed on top of Super Heavy in a matter of hours.

Tesla offers new feature to save battery and reduce phantom drain

While in Low Power Mode, your vehicle continues to use energy for standby functions, screen activity, and Tesla app interactions. In cold weather, available energy may drop more quickly.”

Tesla is offering a new feature to help owners save battery and reduce phantom drain, an issue that some have complained of with their cars.

While Teslas are some of the most efficient EVs on the market, they utilize energy and battery life when they’re parked to keep certain features, like Sentry Mode, Summon Standby, and others, active in preparation for potential events that occur.

Keeping these features ready to perform utilizes energy, and if your car is parked at an airport where it could be sitting stagnant for a few days, the battery percentage could start to dwindle pretty significantly.

Because of this, Tesla is rolling out a new feature called “Low Power Mode,” which will automatically disable a handful of settings to combat battery dwindling and phantom battery drain.

Tesla writes in the release notes for the feature:

“When Low Power Mode is enabled, your vehicle will conserve energy by automatically disabling the following features:

    • Sentry Mode
    • Summon Standby
    • Outlets
    • Keep Accessory Power On
    • Keep Climate On and Camp Mode
    • Scheduled Preconditioning
    • Cabin Overheat Protection

While charging with Low Power Mode enabled:

    • Sentry Mode and accessory power will remain available
    • Keep Climate On and Camp Mode are only available when Supercharging

While in Low Power Mode, your vehicle continues to use energy for standby functions, screen activity, and Tesla app interactions. In cold weather, available energy may drop more quickly.”

This feature seemed to be a reaction to a past issue that an owner had as their Cybertruck continued to utilize energy even though the pickup was parked at an airport and the owner was in Japan. The Cybertruck had utilized a lot of energy to keep standby functions active, which left the owner in an interesting spot when they returned.

CEO Elon Musk stepped in, and it seems this feature might have been a reaction to that situation. This is an ideal thing to use if you’re looking to conserve your battery’s state of charge.

Tesla is bringing back something it took from the Model 3…for a price

“Modify your Model 3 by replacing the turn signal buttons on your steering wheel with turn signal stalks. This modification is included in the purchase price and is installed by a Tesla Service Center.”

Tesla is bringing back the Model 3’s turn signal stalk in China after removing the part with the refresh of the all-electric sedan early last year.

However, it is going to cost you.

In 2024, Tesla launched the Model 3 “Highland,” a refreshed version of the vehicle that included several large-scale changes. One of the most noticeable was the lack of a turn signal stalk, something the company chose to remove and instead implement turn signal buttons on the steering wheel.

The buttons were met with mixed reviews, as some drivers complained that it was too difficult to get used to them. Others had no problem with the change, noting that it was slightly more convenient for them or that they enjoyed the minimalistic look.

Now, Tesla is offering Model 3 owners in China the opportunity to replace the stalk for a price of ¥ 2,499, or about $350:

“Modify your Model 3 by replacing the turn signal buttons on your steering wheel with turn signal stalks. This modification is included in the purchase price and is installed by a Tesla Service Center.”

Tesla notes on its website that the service is available for Model 3 vehicles without stalks manufactured after February 7, 2025. Any car without a stalk that was manufactured before that date will have the service available to them in the future.

Installation can be performed at a Service Center or by the owner. However, Tesla notes that it is not responsible for any damages resulting from self-installation and recommends that the part be put in by an employee.

The cockpit of the Tesla lineup has been under intense scrutiny by the company in recent years. After a few changes to things like the stalk, steering wheel shape, and others, Tesla has usually given drivers the chance to have things reverted back to their preferences if they want.

They did this for the Model S and Model X a few years ago after implementing the yoke steering wheel.

The stalk was not supposed to be removed from the Model 3 and Model Y, but Tesla chose to do so with the refresh last year.

It seems the minimalization of the cockpit, overall, is a move that prepares drivers for autonomy, as eventually, Teslas will be void of pedals, steering wheels, and any other apparatus that are used to control the car.

Tesla launches new loaner program that owners will love

Tesla is now giving owners the opportunity to rent a vehicle from them, and it includes a few very attractive features that will have you second-guessing another loaner from insurance.

Tesla has launched a new loaner program that owners will love, as it resolves some concerns over a replacement vehicle while it is being repaired.

Earlier this week, Tesla launched the option to rent a Tesla loaner vehicle for just $45 per day if your vehicle is in Collision Repair. Collision repairs did not formerly warrant the issuance of loaner vehicles, as the insurance provider of the car owner would provide transportation arrangements.

Tesla is now giving owners the opportunity to rent a vehicle from them, and it includes a few very attractive features that will have you second-guessing another loaner from insurance.

The Tesla you rent while your car is in collision repair will come with free Full Self-Driving, free Supercharging, and free toll coverage, no small print included.

All things considered, this is a great deal for those who require a car for transportation while their car is being repaired.

The cost of Supercharging and Full Self-Driving alone would warrant the $45 per day price tag. Add in the tolls for those who commute on turnpikes for work or are planning an extensive trip that would require it, and it truly becomes an even more attractive deal.

Tesla has done a good job at improving its Service division over the past few years, and it truly needed it. In hopes of launching an F1-style service experience, Tesla started doing away with some of its perks, including loaner vehicles for single-day visits and even Uber credits.

However, it has listened to the complaints of its owners and tried to cater an experience that is more advantageous and less of a hassle. It’s already made tremendous steps in the past few years, and this is the icing on the cake.
