SpaceX planning docs reveal Starship's April Fools' Day testing plans
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 announced its Spring 2026 software update, and it’s the most feature-dense seasonal release the company has put out. The update covers twelve named changes spanning FSD, voice AI, safety lighting, dashcam storage, and pet display customization, among other things.
The centerpiece for owners with AI4 hardware is a redesigned Self-Driving app. The new interface lets owners subscribe to Full Self-Driving with a single tap and view ongoing FSD usage stats directly in the vehicle.
Grok gets its biggest in-car upgrade yet. The update adds a “Hey Grok” hands-free wake word along with location-based reminders, so a driver can now say “remind me to pick up groceries when I get home” without touching the screen. Grok first arrived in vehicles in July 2025, but each update has pushed it closer to genuine daily utility. Musk framed the broader vision clearly at Davos in January, saying Tesla is “really moving into a future that is based on autonomy.”
On safety, the update introduces enhanced blind spot warning lights that integrate directly with the cabin’s ambient lighting, building on the blind spot door warning that arrived in update 2026.8.
Dog Mode has been renamed Pet Mode and now lets owners choose a dog, cat, or hedgehog icon and add their pet’s name to the display.
Dashcam retention now extends up to 24 hours, up from the previous one-hour rolling loop, with a permanent save option for any clip. Weather maps now show rain and snow with better color differentiation and include the past hour of precipitation data along the route.
Tesla has now established a clear rhythm of two major OTA pushes per year. As with last year’s Spring update, that cycle started taking shape in 2025 with adaptive headlights and trunk customization. The 2025 Holiday Update then added Grok to the vehicle for the first time. This Spring follows that structure: the Holiday update introduces new architecture, and the Spring update broadens it across the fleet.
Two notable features still did not make it. IFTTT automations, which launched in China earlier this year, were held back from this North American release for unknown reasons, and Apple CarPlay remains absent, reportedly still delayed by iOS 26 and Apple Maps compatibility issues.
Below is the full list of feature updates released by Tesla.

Tesla launches new Model Y interior option
Produced at Gigafactory Shanghai, the update applies to all five-seat Premium Model Y configurations and started being seen on customer deliveries this week. The move marks the first major interior refresh for the compact crossover since its global debut.
Tesla has rolled out a striking new interior choice for its best-selling Model Y in China, replacing the long-familiar white cabin with a fresh option: Zen Grey.
Produced at Gigafactory Shanghai, the update applies to all five-seat Premium Model Y configurations and started being seen on customer deliveries this week. The move marks the first major interior refresh for the compact crossover since its global debut.
The Zen Grey interior swaps the classic black-and-white contrast for a softer, more unified palette. Seats, door panels, and center console trim now feature a warm light-grey tone that covers far more surface area than before.
Previously, black accents on the console, door handles, and lower dashboard are now color-matched in the same pebbled vegan leather, creating a brighter, less clinical cabin.
Tesla describes the material as durable and easy to maintain while delivering a noticeably more premium feel. Early photos and videos from Chinese owners show the new shade reflecting natural light beautifully, giving the spacious Model Y an even airier, more inviting atmosphere without sacrificing the minimalist design customers expect:

The change is not an added-cost upgrade but a direct replacement for the discontinued white interior on Shanghai-built vehicles. Customers configuring a new Model Y in China, Hong Kong, or Macau now see Zen Grey as the default light-colored choice.
The update also flows to export markets supplied by Giga Shanghai, including Australia, New Zealand, South Korea, Japan, and the Philippines. Tesla has used its Chinese factory as an innovation hub before, and executives appear to be testing broader appeal with this subtler, warmer tone that avoids the high-maintenance reputation sometimes associated with bright white leather.
Beyond the interior, the refreshed Model Y from Shanghai includes minor exterior tweaks such as blacked-out badges on some trims and optional dark 20-inch wheels.
These changes arrive as Tesla faces stiff competition from domestic EV makers in its largest market. By refreshing the Model Y’s cabin without raising prices, the company is signaling continued commitment to value and constant improvement.
With over 1.2 million Model Y units already on Chinese roads, the Zen Grey launch gives existing owners a fresh talking point and new buyers another reason to choose Tesla. As deliveries ramp up this month, the updated interior is expected to become the dominant light-colored choice across the Asia-Pacific region.
Tesla has not yet confirmed whether the Zen Grey will reach Fremont, Austin, or Berlin-built Model Ys, but Shanghai’s track record suggests the option could spread quickly if customer feedback remains strong.

Tesla launches 200mph Model S “Gold” Signature in invite-only purchase
Tesla’s final 350-unit Signature Edition closes the book on two cars that changed everything.
Tesla has announced a super limited Signature Edition run of 250 Model S Plaid and 100 Model X Plaid units as an invite only purchase in a bid to give its original flagship vehicles a proper send-off.
When the Model S first launched in 2012, the first 1,000 units sold were “Signature” editions that required a $40,000 deposit and cost nearly $100,000 each. Those early buyers were Tesla’s first real believers. This new Signature Edition deliberately echoes that moment, bookending a 14-year run with numbered collector hardware.
Both models are finished in an exclusive Garnet Red paint not available on any current Tesla production vehicle, with gold Tesla T badges up front, a gold Plaid badge and Signature badge at the rear, and a white Alcantara interior featuring gold Plaid seat badges, gold piping, Signature-marked door sills, and a numbered dash plate. The Model S adds carbon ceramic brakes with gold calipers. Every unit ships with Tesla’s Luxe Package, bundling Full Self-Driving (Supervised), four years of Premium Service, free lifetime Supercharging, and a Signature Edition key fob. Both are priced at $159,420, a roughly $35,000 premium over standard Plaid inventory.
The discontinuation is part of a broader strategic shift. At Tesla’s Q4 2025 earnings call, Musk described the decision as “slightly sad” but necessary, saying: “It’s time to basically bring the Model S and X programs to an end with an honorable discharge, because we’re really moving into a future that is based on autonomy.”
The Fremont factory floor that built these cars is being converted to manufacture Optimus humanoid robots, with a target of one million units annually.
