SpaceX’s Starship rocket just breathed fire for the first time (and survived)
SpaceX’s Starship rocket is a step closer to flight after the fourth full-scale prototype successfully fired up its high-performance Raptor engine for the first time and survived the ordeal.
By far the biggest technical milestone SpaceX’s Starship program has passed since its creation, the Starship serial number 4 (SN4) prototype’s May 5th static fire was just the latest in a series of rapid-fire tests completed over the last several days. The ship’s journey began back in late March when SpaceX technicians began integrating the first sections of its steel hull. Less than a month later, SpaceX officially completed Starship SN4’s tank and engine section – missing only a nosecone and header tanks – and rolled the rocket to the launch and test pad on April 23rd.
Barely two days later, Starship SN4 entered the testing phase, passing what CEO Elon Musk described as an “ambient pressure test” used to verify the structural integrity of the rocket’s propellant tanks with harmless nitrogen gas. Less than a day after that pressure test was completed, SpaceX kicked off a “cryogenic proof test” with the Starship – the same test that destroyed three full-scale prototypes in the five months prior.

In the early morning of April 26th, Starship SN4 thus became the first full-scale prototype to pass (and survive) a cryogenic proof test, in which the ship’s normal liquid oxygen and methane was replaced with similarly frigid but non-explosive liquid nitrogen. According to Musk, SN4 was only pressurized to 4.9 bar (~70 psi), quite a distance away from the ~8.5 bar needed for safe orbital flight but reportedly more than enough to perform a small flight test.
Of course, Starship SN4 would first have to complete a bevy of additional tests – all arguably riskier than the cryogenic proof test it was the first to pass. That second, more challenging phase of testing began six days later on May 2nd.

After some limited fueling effectively marking Starship SN4’s first partial wet dress rehearsal (WDR), SpaceX aborted the first test attempt on May 2nd. On May 3rd, Starship SN4 was successfully loaded with propellant once more and wound up performing what is known as a spin prime test with its lone Raptor engine. Over the course of a few hours, SpaceX then recycled (and rechilled) the ship’s methane propellant and successfully performed a preburner test, igniting two gas generators that spin up Raptor’s turbines and eventually mix in the combustion chamber.
Less than 24 hours later, SpaceX turned Starship SN4 around for the grand finale – an actual Raptor ignition test, also known as a static fire. Per NASASpaceflight’s unofficial livestream of the event, made possible thanks to local resident BocaChicaGal, Starship ignited its Raptor engine – a historic first for the launch vehicle program – at 8:57pm CDT on May 5th (01:57 UTC, May 6). Musk confirmed just a few hours after that the ignition test – lasting about 3 seconds – had been completed successfully.



With that crucial milestone now behind it, Starship SN4 – perhaps pending an additional test or two – should effectively be clear to begin preparations for a 150m (500 ft) hop test later this month. Almost entirely contingent upon receiving a Federal Aviation Administration (FAA) launch license, that process could be finished tomorrow or take several days – or even weeks – to complete. Starship already has landing legs installed and wont need a nosecone for such a short and slow hop, but SpaceX may also need to install some kind of attitude control system (likely gas thrusters) before SN4 can safely fly.
Stay tuned for updates as we learn more about when a full-scale SpaceX Starship is scheduled to fly for the first time.

Elon Musk hints at “official ceremony” with throwback photo to close Tesla Model S, Model X chapter
Elon Musk promises an official ceremony to mark the end of Tesla Model S and Model X production.
Tesla has officially begun winding down production of the Model S and Model X, sending farewell emails to U.S. customers on March 27 and updating the website to reflect the end of the line. Shoppers visiting Tesla.com now find only a limited set of Model S and Model X inventory units available for purchase, with no option to configure a new factory build. The move formalizes what CEO Elon Musk announced on the company’s Q4 2025 earnings call in January, when he said it was “time to basically bring the Model S and X programs to an end with an honorable discharge.”
Musk posted on X a throwback photo of himself speaking at the Model S production launch in 2012, and noting “We will have an official ceremony to mark the ending of an era. I love those cars.”
The mention of an official ceremony is notable. Tesla has not held a formal farewell event for a vehicle before, and Musk’s wording suggests this will be something deliberate rather than a quiet line shutdown. Given that Musk’s X post shows a photo of him on stage with a microphone in front of an audience at the Fremont factory, it wouldn’t be too far-fetched to expect a closing ceremony to take place at the same location. Perhaps? Whether it becomes a public event, a private gathering for employees, or a livestreamed moment on X remains to be seen.
Custom orders of the Tesla Model S & X have come to an end. All that’s left are some in inventory.

The Model S first went on sale nearly fifteen years ago and was Tesla’s first fully in-house designed vehicle, proving that an electric car could be fast, desirable, and capable of long distance on a single charge. The Model X followed in 2015, turning heads with its unmistakable and distinctive falcon-wing doors, while becoming one of the first all-electric SUVs on the market. Tesla’s two flagship vehicles would ultimately push legacy automakers to take all-electric transportation seriously and help fund development of the more affordable Model 3 and Model Y.
By 2025, however, both models had been reduced to a rounding error in Tesla’s sales figures. Musk was direct about what comes next, stating “We are going to convert that production space to an Optimus factory. It’s part of our overall shift to an autonomous future.”

That shift is already underway. Tesla officially started Optimus Gen 3 production at its Fremont factory in January 2026, with the line targeting a run rate of one million units per year. The Gen 3 robot features 22 degrees of freedom per hand, runs on Tesla’s AI5 chip, and shares the same neural network architecture as Full Self-Driving. A dedicated Optimus factory at Gigafactory Texas is also under construction, with a planned annual capacity of 10 million units. The production lines that once built the Model S and Model X are being converted to support that ramp.
Tesla confirmed it will continue to support existing owners with service, software updates, and parts for as long as people own the vehicles. For buyers still interested in a new example, remaining U.S. inventory is discounted and the window is closing fast.

Elon Musk announces disappointing Tesla Optimus update
In a post on X on March 31, Musk stated that Optimus 3 is mobile but requires some finishing touches before it is ready to be shown to the world. This update comes on the final day of the first quarter, a period when Tesla had previously signaled expectations for a Gen 3 reveal.
Elon Musk announced a disappointing update to the unveiling of Tesla Optimus and its third-generation iteration, missing a timeline it aimed to hit in the first quarter of the year.
Musk has confirmed that the highly anticipated Optimus Gen 3 humanoid robot is already walking around and operational, yet the public unveiling will face a short delay as the company applies final refinements.

The announcement follows reports of Optimus Gen 3 appearing at the Tesla Diner in Los Angeles, where it was observed serving and moving about until sunset. Images and videos shared by observers captured the robot in action, highlighting its progress in real-world mobility.
Tesla had aimed to showcase the production intent version of Optimus Gen 3 during the first quarter of 2026, positioning it as a major step toward factory deployment and eventual commercial availability. Musk has described the robot as featuring advanced capabilities, including highly dexterous hands with significant degrees of freedom, powered by Tesla’s AI systems for complex tasks.
This minor postponement aligns with Tesla’s iterative approach to development. Earlier statements from Musk indicated that Gen 3 would represent the most advanced humanoid robot yet, designed primarily for internal factory use before scaling to external customers.

Production timelines point toward low-volume output starting in the summer of 2026, with volume ramp-up targeted for 2027. The delay underscores the company’s commitment to quality over speed, ensuring the robot meets rigorous standards for safety and performance in practical environments.
Optimus represents a cornerstone of Tesla’s long-term vision beyond electric vehicles. Musk has repeatedly emphasized that successful humanoid robotics could transform industries by addressing labor shortages and enabling new forms of productivity.
Competitors in the space continue to advance their own platforms, yet Tesla’s vertical integration, from custom actuators to end-to-end AI training, positions Optimus as a potential leader. Community reactions on social media range from excitement over visible progress to impatience with shifting timelines, a familiar pattern in Tesla’s innovation journey.
Investors and enthusiasts view Optimus as critical to Tesla’s valuation, potentially surpassing its automotive business in scale. With the robot already demonstrating walking and basic interactions, the finishing touches likely involve software polishing, hardware fine-tuning, and reliability enhancements.
Musk’s update suggests the reveal could arrive in the coming weeks or months, maintaining momentum toward broader deployment.
As Tesla pushes the boundaries of physical artificial intelligence, this latest development keeps Optimus in the spotlight. The company continues to prioritize rapid iteration while delivering on its promises to shareholders and customers. The robotics revolution at Tesla appears closer than ever, promising profound impacts on manufacturing, services, and daily life in the years ahead.

Countdown: America is going back to the Moon and SpaceX holds the key to what comes after
NASA’s Artemis II launches Wednesday, sending humans near the Moon for the first time since 1972.
For the first time since Apollo 17 touched down on the lunar surface in December 1972, the United States is sending humans back toward the Moon. NASA’s Artemis II mission is set to launch as early as this week from Kennedy Space Center in Florida, carrying four astronauts on a 10-day journey around the Moon and back to Earth. It will not land anyone on the surface this time, but it is the first crewed flight in over half a century to travel beyond low Earth orbit, and it sets the stage for Elon Musk’s SpaceX missions to follow.
The mission uses NASA’s Space Launch System rocket and the Orion spacecraft, which will fly around the Moon before splashing down in the Pacific Ocean around April 10. For context, an uncrewed Artemis I flew the same path in 2022, proving the hardware worked. Artemis II now tests it with people aboard.
According to NASA’s official countdown blog, launch preparations are on track with an 80 percent chance of favorable weather. “Hey, let’s go to the moon!” Commander Wiseman told reporters upon arriving at Kennedy Space Center.
Beyond Artemis II lies the lander question, and that is where SpaceX enters directly. In 2021, NASA awarded SpaceX a $2.89 billion contract to develop the Starship Human Landing System, a modified version of Starship designed to ferry astronauts from lunar orbit to the surface. The original plan called for SpaceX to deliver that lander for Artemis III, which was to be the first crewed lunar landing. Timing for Starship development, however, caused NASA to restructure the mission sequence entirely.
Before SpaceX’s Starship Human Landing System (HLS) can put anyone on the Moon, it has to solve a problem no rocket has demonstrated at scale, which is refueling in orbit. Because the Starship HLS requires approximately ten tanker launches worth of propellant loaded into a depot in low Earth orbit before it has enough fuel to reach the lunar surface, SpaceX plans to conduct this refueling process using its upgraded V3 Starship. And until that demonstration flies and succeeds, the Starship moon lander remains a question mark.
SpaceX’s Starship V3 is almost ready and it will change space travel forever
In February 2026, NASA Administrator Jared Isaacman confirmed that Artemis III, now planned for mid-2027, and will instead test lunar landers in low Earth orbit, with the actual landing pushed to Artemis IV that’s targeted for 2028.
Musk responded to earlier criticism of SpaceX’s schedule by posting on X that his company is “moving like lightning compared to the rest of the space industry,” and added that “Starship will end up doing the whole Moon mission.” The contract competition was also reopened in October 2025 by then NASA chief Sean Duffy, who cited Starship’s delays and said the agency needed speed given China’s own stated goal of landing astronauts on the Moon by 2030.
They won’t. SpaceX is moving like lightning compared to the rest of the space industry.
Moreover, Starship will end up doing the whole Moon mission. Mark my words.

Artemis came from the first Trump administration’s 2017 Space Policy Directive 1, which directed NASA to return humans to the Moon. The program picked up pace through the 2020s, with the Orion spacecraft and SLS taking years to develop at enormous costs. SpaceX entered the picture in 2021 as the chosen lander contractor, tying the commercial space sector into what had historically been an all government undertaking.
Whether SpaceX’s Starship ultimately carries astronauts to the lunar surface or shares that role with Blue Origin’s competing lander, this week’s Artemis II launch is the necessary first step. Getting four humans to the Moon’s vicinity and back safely is the proof of concept everything else depends on.
