Elon Musk: SpaceX’s first orbital Starship launch “highly likely” in Q1 2023
SpaceX’s first Starship orbital launch mount (OLM) appears to have passed a busy week of stress-testing, clearing the way for the company to transport a finished Super Heavy booster to the pad.
Using the same launch mount, that Starship booster is expected to attempt to complete some of the riskiest and most challenging tests SpaceX has ever conducted at its Starbase rocket development facilities. The schedule for that testing is unclear, but after an unusually drawn-out period of qualification testing, Super Heavy Booster 7 (B7) could soon attempt a full static fire test of all 33 of its Raptor 2 engines. Either before or after that crucial test, SpaceX is also expected to install Ship 24 (S24) on top of Super Heavy B7 for Starship’s first full-stack “wet dress rehearsal.”
Ultimately, if that testing produces the results SpaceX wants to see, CEO Elon Musk says that Starship could attempt its first orbital launch as early as late February or March 2023.
We have a real shot at late February. March launch attempt appears highly likely.— Elon Musk (@elonmusk) January 8, 2023
The update that's rolling out to the fleet makes full use of the front and rear steering travel to minimize turning circle. In this case a reduction of 1.6 feet just over the air— Wes (@wmorrill3) April 16, 2024
Booster 7
Super Heavy B7 first left SpaceX’s Starbase factory in March 2022 and has been in a continuous flux of testing, repairs, upgrades, and more testing in the nine months since. The 69-meter-tall (~225 ft), 9-meter-wide (~30 ft) steel rocket was severely damaged at least twice in April and July, requiring weeks of substantial repairs. But neither instance permanently crippled the Starship booster, and Booster 7 testing has been cautious but largely successful since the rocket’s last close call.
Following its return to the OLS in early August, Super Heavy B7 has completed six static fire tests of anywhere from one to fourteen of its 33 Raptor engines. It has almost certainly dethroned Falcon Heavy to become the most powerful SpaceX rocket ever tested. And on January 8th, 2023, SpaceX rolled the rocket back to Starbase’s orbital launch site (OLS) for the seventh time. According to statements made by CEO Elon Musk and a presentation from a NASA official, the last major standalone test between Booster 7 and flight readiness is a full 33-engine static fire. Together, B7’s 33 Raptor 2 engines could produce up to 7600 tons (16.7 million lbf) of thrust at sea level, likely making Starship the most powerful rocket stage in the history of spaceflight.
Ship 24
Starship prototype S24’s path has been a bit less rocky. The ship has needed some less obvious repairs, particularly right after its first tests in May 2022. Since August 2022, Ship 24 has completed three static fire tests – all seemingly successful. Most importantly, one of those tests ignited all six of S24’s Raptor engines, potentially qualifying it for an orbital launch attempt. Most recently, SpaceX completed a series of mysterious repairs, replaced and static-fired one of S24’s engines, and removed the Starship from its test stand.
With Booster 7 now awaiting installation on Starbase’s orbital launch mount and Ship 24 near-simultaneously removed from its test stand, it appears that SpaceX may attempt a different test before Super Heavy’s full static fire. Instead, SpaceX could start by stacking Ship 24 and Booster 7 and conducting a full-stack wet dress rehearsal (WDR) before shifting focus to Booster 7’s riskier static fire.
A wet dress rehearsal is a routine test conducted before a rocket launch and is generally designed to simulate every aspect of a launch save for engine ignition and liftoff. Most importantly, that involves fully filling the rocket with propellant and passing all of the checks the same rocket would need to pass to be cleared for launch. For Starship, the largest rocket ever built, a full propellant load means filling both stages with an extraordinary ~5000 tons of liquid oxygen and liquid methane propellant. SpaceX also needs to fill the rocket fast enough to keep that propellant supercool, which increases its density and overall performance.
The first full-stack WDR will thus test Starbase’s launch facilities just as much as Booster 7 and Ship 24. SpaceX has conducted many several Starship WDRs, but not with Ship 24. It’s also never fully filled a Super Heavy booster with real propellant, let alone both stages at once. It’s likely that issues will be discovered as SpaceX pushes the envelope, likely requiring multiple attempts.
OLS
In the spirit of caution, SpaceX has even taken the unusual step of stress-testing Starship’s orbital launch mount with a custom jig. In the first week of 2023, SpaceX used that jig to load pairs of the OLM’s 20 hold-down clamps with hundreds of tons of ballast, ensuring that they can withstand the immense weight of a fully-fueled Starship. Proof tests of Super Heavy B4 and B7 have likely subjected the OLM to 2000+ tons of force, but a full Starship will weigh more than double the maximum weight the OLM has experienced to date.
Plenty of risk remains and SpaceX is trading speed for caution, but this extra-cautious step has likely reduced the risk of the launch mount’s structure failing during wet-dress and static fire testing. According to Musk, SpaceX has a “real shot” at preparing Starship for a “late February” orbital launch attempt. Nonetheless, Musk also implied that a full-stack WDR and 33-engine static fire would “probably” be completed “in a few weeks” in September 2022. What is clear is that SpaceX is more committed than ever before to avoiding a catastrophic failure during Starship’s first orbital launch attempt.

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.
