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.

SpaceX CEO Elon Musk shared a brief Starship V3 update in a post on social media platform X, stating the next launch attempt of the spacecraft could take place in about four weeks.

The comment was posted on Musk’s official account on social media platform X.

Musk’s update suggests that Starship Flight 12 could target a launch around early April, though the schedule will depend on several remaining milestones at SpaceX’s Starbase launch facility in Texas.

Among the key steps is testing and certification of the site’s new launch tower, launch mount, and tank farm systems. These upgrades will support the next generation of Starship vehicles.

Booster 19 is expected to roll to the launch site and be placed on the launch mount before returning to the production facility to receive its 33 Raptor engines. The booster would then return for a static fire test, which could mark the first time a Super Heavy booster equipped with Raptor V3 engines is fired on the pad.

Ship 39 is expected to undergo a similar preparation process. The vehicle will likely return to the production site to receive its six engines before heading to Massey’s test site for static fire testing.

Once both stages are prepared, the booster and ship will roll out to the launch site for the first full stack of a V3 Super Heavy and V3 Starship. A full wet dress rehearsal is expected to follow before any launch attempt.

Elon Musk has previously shared how SpaceX plans to eventually recover Starship’s upper stage using the launch tower’s robotic arms. Musk noted that the company will only attempt to catch the Starship spacecraft after two successful soft landings in the ocean. The approach is intended to reduce risk before attempting a recovery over land.

“Should note that SpaceX will only try to catch the ship with the tower after two perfect soft landings in the ocean. The risk of the ship breaking up over land needs to be very low,” Musk wrote in a post on X.

Such a milestone would represent a major step toward the full reuse of the Starship system, which remains a central goal for SpaceX’s long-term launch strategy.

Tesla has opened its first public Tesla Semi Megacharger site in Los Angeles. The station reportedly offers up to 750 kW charging speeds and is open to Tesla Semi customers.

The development was highlighted in a post on social media platform X by the official Tesla Semi account.

Tesla Semi Megachargers

The Los Angeles site seems to be the first public Tesla Semi Megacharger that is not located at a Tesla factory. It is also the third Megacharger site currently visible on Tesla’s map.

The Megacharger system is designed specifically for the Tesla Semi and is capable of delivering extremely high charging speeds to support long-haul trucking operations. Infrastructure such as this will likely play a key role in making the Semi competitive with diesel-powered transport trucks.

Tesla’s progress with the Semi has also drawn attention in recent days after Elon Musk biographer Ashlee Vance shared photos from inside the Tesla Semi factory near Giga Nevada. The images suggested that preparations for higher production volumes may be underway, hinting that a broader ramp of the Tesla Semi’s production indeed be approaching.

New deployment strategies

Tesla has continued expanding its broader charging network through several new strategies aimed at accelerating infrastructure deployment. One of these initiatives is the Supercharger for Business program, which allows third parties to purchase Tesla Supercharger equipment and deploy charging stations while still integrating with Tesla’s network.

The program recently marked a milestone in Alpharetta, Georgia, where the city deployed four 325 kW city-branded Superchargers near the Alpharetta Department of Public Safety on Old Milton Parkway. The chargers support the city’s Tesla Model Y police vehicles while also remaining accessible to the public.

As per a report from EVwire, the project was designed not only to support fleet charging but also to generate economic returns that could offset the city’s investment. Tesla’s Supercharger for Business program has already attracted several participants, including businesses and charging providers such as Suncoast Charging, Pie Safe bakery in Idaho, Francis Energy in Oklahoma, and Wawa convenience stores.

The Boring Company said its Vegas Loop system transported roughly 82,000 passengers during the recent CONEXPO-CON/AGG construction trade show in Las Vegas. The event was held at the Las Vegas Convention Center (LVCC) from March 3-7, 2026. 

The Loop’s feat was highlighted by The Boring Company in a post on its official account on social media platform X.

CONEXPO-CON/AGG 2026

CONEXPO-CON/AGG is one of the largest construction trade shows in North America. This year’s event was quite impressive, attracting more than 140,000 construction professionals from 128 countries across the world.

Considering the number of this year’s attendees, the LVCC Loop seemed to have proven itself to be a very useful transportation solution. A video posted by The Boring Company on its official X account featured attendees expressing their enthusiasm for the underground transport system, with some stating that they would like to see similar tunnels across Las Vegas.

The LVCC Loop is only part of the greater Vegas Loop network, which is actively under construction.

New Vegas Loop extensions

One of the newest additions is a station at the Fontainebleau Las Vegas resort on the Strip. The station is located on level V-1 of the resort’s south valet area, according to a report from the Las Vegas Review-Journal. From the Fontainebleau, passengers can travel free of charge to stations serving the Las Vegas Convention Center, as well as to Loop stations at Encore and Westgate.

The system is also expanding beyond the Strip corridor. In December, The Boring Company began offering Vegas Loop rides to and from Harry Reid International Airport. These trips include a limited above-ground segment after receiving approval from the Nevada Transportation Authority to allow surface street travel tied to Loop operations.

The Boring Company President Steve Davis previously told the Review-Journal that the University Center Loop segment, which is currently under construction, is expected to open in the first quarter of 2026. The extension would allow Loop vehicles to travel beneath Paradise Road between the convention center and the airport, with a planned station just north of Tropicana Avenue.
