SpaceX Starship rocket could move to the launch pad today
SpaceX has finished stacking its fourth full-scale Starship prototype and public schedules show that the rocket could be moved to a nearby launch and test pad as early as April 20th.
Known as Starship serial number 4 (SN4), the rocket will be the third full-scale vehicle completed since the start of serial production, while Starship Mk1 – the first full-scale prototype – was built far more slowly and with different methods. Mk1 was destroyed during one of its first cryogenic liquid nitrogen ‘proof’ tests in November 2019, nearly nine months after assembly began in February. After Mk1’s failure, SpaceX spent about two months rapidly expanding and upgrading its Boca Chica, Texas Starship factory.
Around the end of January 2020, SpaceX kicked off the production of its first serial prototype – logically deemed SN1. Less than a month after its first steel rings were stacked and welded together, SpaceX transported the completed prototype to the launch pad. On February 28th, what CEO Elon Musk later described as a fault in its engine section “thrust puck” destroyed Starship SN1 during one of its first cryogenic proof tests. Barely a month later and after SN2 was modified into a “thrust puck” test tank and successfully tested, Starship SN3 rolled to the launch pad and was destroyed by operator and test design errors on April 3rd. Now, barely two weeks after SN3, Starship SN4 is about to begin testing.
By all appearances, work on Starship SN4 began around March 23rd, continuing a production schedule that has been consistently completing a full-scale rocket prototype every four or so weeks. While SpaceX has taken the unprecedented step of reusing a section of a prototype (SN3) destroyed during testing, every other aspect of the rocket is new and built more or less from scratch.
Just two days after Starship SN3’s salvaged skirt and SN4’s new engine section and aft liquid oxygen tank dome were stacked and welded together, SpaceX technicians attached a crane to the upper two-thirds of the rocket’s tank section and stacked it on top of the newly-finished engine section. 24 hours later, SpaceX teams have completed at least one circumferential seam weld, with a second soon to be finished.
Once that last weld is complete and passes inspections, Starship SN4 will be ready to be lifted onto a transporter and rolled down the road to SpaceX’s dedicated launch and test facilities. Of course, like SN3 and SN1 before it, SpaceX will likely still have a few days of work to get Starship SN4 ready for testing once it’s been moved to the pad.
Using Starship SN3’s timeline, Starship SN4 could be transported to the pad as early as April 19th or 20th and ready for testing by April 24th or 25th. This meshes well with a publicly-available road closure schedule, required because SpaceX often needs to close a public highway for certain Starship transport and testing operations. Per Cameron County’s website, SpaceX has a transport-related closure planned on April 20th. The first testing-related closure begins on Sunday, April 26th and lasts from 9am to midnight, with backups on Monday and Tuesday.
As always, delays should come as no surprise with prototype testing, and schedules are always fluid and liable to change at any second. Regardless, it looks like Starship SN4 is perhaps just a week from its first round of testing.

Starlink restrictions are hitting Russian battlefield comms: report
The restrictions have reportedly disrupted Moscow’s drone coordination and frontline communications.
SpaceX’s decision to disable unauthorized Starlink terminals in Ukraine is now being felt on the battlefield, with Ukrainian commanders reporting that Russian troops have struggled to maintain assault operations without access to the satellite network.
The restrictions have reportedly disrupted Moscow’s drone coordination and frontline communications.
Lt. Denis Yaroslavsky, who commands a special reconnaissance unit, stated that Russian assault activity noticeably declined for several days after the shutdown. “For three to four days after the shutdown, they really reduced the assault operations,” Yaroslavsky said.
Russian units had allegedly obtained Starlink terminals through black market channels and mounted them on drones and weapons systems, despite service terms prohibiting offensive military use. Once those terminals were blocked, commanders on the Ukrainian side reported improved battlefield ratios, as noted in a New York Post report.
A Ukrainian unit commander stated that casualty imbalances widened after the cutoff. “On any given day, depending on your scale of analysis, my sector was already achieving 20:1 (casuality rate) before the shutdown, and we are an elite unit. Regular units have no problem going 5:1 or 8:1. With Starlink down, 13:1 (casualty rate) for a regular unit is easy,” the unit commander said.
The restrictions come as Russia faces heavy challenges across multiple fronts. A late January report from the Center for Strategic and International Studies estimated that more than 1.2 million Russian troops have been killed, wounded, or gone missing since February 2022.
The Washington-based Institute for the Study of War also noted that activity from Russia’s Rubikon drone unit declined after Feb. 1, suggesting communications constraints from Starlink’s restrictions may be limiting operations. “I’m sure the Russians have (alternative options), but it takes time to maximize their implementation and this (would take) at least four to six months,” Yaroslavsky noted.

Tesla Korea hiring AI Chip Engineers amid push for high-volume AI chips
Tesla Korea stated that it is seeking “talented individuals to join in developing the world’s highest-level mass-produced AI chips.”
In a recent post on X, Tesla Korea announced that it is hiring AI Chip Design Engineers as part of a project aimed at developing what the company describes as the world’s highest-volume AI chips. CEO Elon Musk later amplified the initiative.
Tesla Korea stated that it is seeking “talented individuals to join in developing the world’s highest-level mass-produced AI chips.”
“This project aims to develop AI chip architecture that will achieve the highest production volume in the world in the future,” Tesla Korea wrote in its post on X.
As per Tesla Korea, those who wish to apply for the AI Chip Design Engineer post should email Ai_Chips@Tesla.com and include “the three most challenging technical problems you have solved.”
Elon Musk echoed the hiring push in a separate post. “If you’re in Korea and want to work on chip design, fabrication or AI software, join Tesla!” he wrote.
The recruitment effort in South Korea comes as Tesla accelerates development of its in-house AI chips, which power its Full Self-Driving (FSD) system, Optimus humanoid robot, and data center training infrastructure.
Tesla has been steadily expanding its silicon development teams globally. In recent months, the company has posted roles in Austin and Palo Alto for silicon module process engineers across lithography, etching, and other chip fabrication disciplines, as noted in a Benzinga report.
Tesla Korea’s hiring efforts align with the company’s long-term goal of designing and producing AI chips at massive scale. Musk has previously stated that Tesla’s future AI chips could become the highest-volume AI processors in the world.
The move also comes amid Tesla’s broader expansion into AI initiatives. The company recently committed about $2 billion into xAI as part of a Series E funding round, reinforcing its focus on artificial intelligence across vehicles, robotics, and compute infrastructure.

SpaceX and xAI tapped by Pentagon for autonomous drone contest
The six-month competition was launched in January and is said to carry a $100 million award.
SpaceX and its AI subsidiary xAI are reportedly competing in a new Pentagon prize challenge focused on autonomous drone swarming technology, as per a report from Bloomberg News.
The six-month competition was launched in January and is said to carry a $100 million award.
Bloomberg reported that SpaceX and xAI are among a select group invited to participate in the Defense Department’s effort to develop advanced drone swarming capabilities. The goal is reportedly to create systems that can translate voice commands into digital instructions and manage fleets of autonomous drones.
Neither SpaceX, xAI, nor the Pentagon’s Defense Innovation Unit has commented on the report, and Reuters said it could not independently verify the details.
The development follows SpaceX’s recent acquisition of xAI, which pushed the valuation of the combined companies to an impressive $1.25 trillion. The reported competition comes as SpaceX prepares for a potential initial public offering later this year.
The Pentagon has been moving to speed up drone deployment and expand domestic manufacturing capacity, while also seeking tools to counter unauthorized drone activity around airports and major public events. Large-scale gatherings scheduled this year, including the FIFA World Cup and America250 celebrations, have heightened focus on aerial security.
The reported challenge aligns with broader Defense Department investments in artificial intelligence. Last year, OpenAI, Google, Anthropic, and xAI secured Pentagon contracts worth up to $200 million each to advance AI capabilities across defense applications.
Elon Musk previously joined AI and robotics researchers in signing a 2015 open letter calling for a ban on offensive autonomous weapons. In recent years, however, Musk has spoken on X about the strengths of drone technologies in combat situations.
