Planning emails published by Cameron County, Texas officials have revealed a more detailed picture of SpaceX’s April Fools’ Day Starship testing plans.

Published soon after SpaceX CEO Elon Musk confirmed that six landing legs have already been installed on Starship SN3, county documents noted that SpaceX has two Starship tests planned on April 1st. The second test is contingent upon the successful completion of the first, which is scheduled to begin as early as 4pm CDT (21:00 UTC).

SpaceX has built up Starship SN3 – the third full-scale prototype to make it to testing – from a handful a separate steel rings into a ~30m (100 ft) tall, 9m (30 ft) wide rocket. Technically, the hardware SpaceX transported from its Boca Chica, Texas factory to an adjacent launch pad on March 29th is just the bottom ~60% of Starship SN3, but it’s undoubtedly the most important part of the ship. The SN3 tank and engine section now installed on a launch mount represents the business half (give or take) of Starship, itself just the upper stage and spacecraft of SpaceX’s next-generation, fully-reusable rocket.

Previous full-scale Starship testing – attempted with the Mk1 and SN1 prototypes on November 2019 and February 2020, respectively – have not gone according to plan. However, for each recent Starship testing failure, SpaceX has subsequently completed one or several ‘proof’ tests with smaller tanks, proving that improved construction methods are technically up to the tasks required of them. Most notably, SpaceX completed two Starship tank pressure tests in January 2020, consecutively reaching ~7.5 and ~8.5 bar (110 and 125 psi) – the latter representing a full 40% safety margin on top of the 6 bar minimum Starship needs for orbital flight.

Most recently, SpaceX completed its third Starship test tank campaign in mid-March, proving less than two weeks later that the design fault that destroyed Starship SN1 had already been rectified. Now, Starship SN3 sits at the same test site, representing the hopeful culmination of the many lessons SpaceX has learned from its prolific testing over the last five months.

Now, Starship SN3’s first series of ground tests are scheduled to begin as early as 4pm CDT, just half an hour or so from the time this article was published. According to documents shared by Cameron County, SpaceX’s plan is to begin with a room-temperature gas test, likely pressurizing Starship SN3 with nitrogen to check for leaks. By testing with gas (instead of water), completing the initial test would leave Starship free to immediately proceed to a more ambitious test. This is precisely SpaceX’s plan: if Starship passes the nitrogen gas test, Starship SN3 could begin a cryogenic liquid nitrogen proof test just three hours later, kicking off no earlier than 8pm CDT (01:00 UTC, April 2).

Featuring a brand new 4K camera, local resident and SpaceX fan LabPadre’s live stream should offer some exceptional, uninterrupted views if or when SpaceX kicks off Starship SN3’s first tests later today.

Tesla adds new feature that will be great for crowded parking situations

This is the most recent iteration of the app and was priming owners for the slowly-released Holiday Update.

Tesla has added a new feature that will be great for crowded parking lots, congested parking garages, or other confusing times when you cannot seem to pinpoint where your car went.

Tesla has added a new Vehicle Locator feature to the Tesla App with App Update v4.51.5.

This is the most recent iteration of the app and was priming owners for the slowly-released Holiday Update.

While there are several new features, which we will reveal later in this article, perhaps one of the coolest is that of the Vehicle Locator, which will now point you in the direction of your car using a directional arrow on the home screen. This is similar to what Apple uses to find devices:

In real time, the arrow gives an accurate depiction of which direction you should walk in to find your car. This seems extremely helpful in large parking lots or unfamiliar shopping centers.

Getting to your car after a sporting event is an event all in itself; this feature will undoubtedly help with it:

Tesla’s previous app versions revealed the address at which you could locate your car, which was great if you parked on the street in a city setting. It was also possible to use the map within the app to locate your car.

However, this new feature gives a more definitive location for your car and helps with the navigation to it, instead of potentially walking randomly.

It also reveals the distance you are from your car, which is a big plus.

Along with this new addition, Tesla added Photobooth features, Dog Mode Live Activity, Custom Wraps and Tints for Colorizer, and Dashcam Clip details.

All in all, this App update was pretty robust.

Tesla CEO Elon Musk shades Waymo: ‘Never really had a chance’

Tesla CEO Elon Musk shaded Waymo in a post on X on Wednesday, stating the company “never really had a chance” and that it “will be obvious in hindsight.”

Tesla and Waymo are the two primary contributors to the self-driving efforts in the United States, with both operating driverless ride-hailing services in the country. Tesla does have a Safety Monitor present in its vehicles in Austin, Texas, and someone in the driver’s seat in its Bay Area operation.

Musk says the Austin operation will be completely void of any Safety Monitors by the end of the year.

With the two companies being the main members of the driverless movement in the U.S., there is certainly a rivalry. The two have sparred back and forth with their geofences, or service areas, in both Austin and the Bay Area.

While that is a metric for comparison now, ultimately, it will not matter in the coming years, as the two companies will likely operate in a similar fashion.

Waymo has geared its business toward larger cities, and Tesla has said that its self-driving efforts will expand to every single one of its vehicles in any location globally. This is where the true difference between the two lies, along with the fact that Tesla uses its own vehicles, while Waymo has several models in its lineup from different manufacturers.

The two also have different ideas on how to solve self-driving, as Tesla uses a vision-only approach. Waymo relies on several things, including LiDAR, which Musk once called “a fool’s errand.”

This is where Tesla sets itself apart from the competition, and Musk highlighted the company’s position against Waymo.

Jeff Dean, the Chief Scientist for Google DeepMind, said on X:

“I don’t think Tesla has anywhere near the volume of rider-only autonomous miles that Waymo has (96M for Waymo, as of today). The safety data is quite compelling for Waymo, as well.”

Musk replied:

“Waymo never really had a chance against Tesla. This will be obvious in hindsight.”

Tesla stands to have a much larger fleet of vehicles in the coming years if it chooses to activate Robotaxi services with all passenger vehicles. A simple Over-the-Air update will activate this capability, while Waymo would likely be confined to the vehicles it commissions as Robotaxis.

Tesla AI5 project begins to move forward

According to a new report from Sedaily, Samsung is accelerating its preparation for U.S. production of the AI5 chips by hiring veteran engineers for its Customer Engineering team.

Tesla supplier Samsung is preparing to manufacture the AI5 chip, which will launch the company’s self-driving efforts even further, with its latest move.

According to a new report from Sedaily, Samsung is accelerating its preparation for U.S. production of the AI5 chips by hiring veteran engineers for its Customer Engineering team, which will help resolve complex foundry challenges, stabilize production and yields, and ensure manufacturing goes smoothly for the new project.

The hiring push signals that Tesla’s AI5 project is moving forward quickly at Samsung, which was one of two suppliers to win a contract order from the world’s leading EV maker.

TSMC is the other. TSMC is using its 3nm process, reportedly, while Samsung will do a 2nm as a litmus test for the process.

The different versions are due to the fact that “they translate designs to physical form differently,” CEO Elon Musk said recently. The goal is for the two to operate identically, obviously, which is a challenge.

Some might remember Apple’s A9 “Chipgate” saga, which found that the chips differed in performance because of different manufacturers.

The AI5 chip is Tesla’s next-generation hardware chip for its self-driving program, but it will also contribute to the Optimus program and other AI-driven features in both vehicles and other projects. Currently, Tesla utilizes AI4, formerly known as HW4 or Hardware 4, in its vehicles.

Tesla teases new AI5 chip that will revolutionize self-driving

AI5 is specialized for use by Tesla as it will work in conjunction with the company’s Neural Networks, focusing on real-time inference to make safe and logical decisions during operation.

Musk said it was an “amazing design” and an “immense jump” from Tesla’s current AI4 chip. It will be roughly 40 times faster, and have 8 times the raw compute, with 9 times the memory capacity. It is also expected to be three times as efficient per watt as AI4.

AI5 will make its way into “maybe a small number of units” next year, Musk confirmed. However, it will not make its way to high-volume production until 2027. AI5 is not the last step, either, as Musk has already confirmed AI6 would likely enter production in mid-2028.
