SpaceX’s upgraded Starship tracking towards Wednesday launch
Update #2: A little over 24 hours after SpaceX’s 25th operational Starlink launch, the company’s first significantly upgraded Starship prototype is tracking towards a launch debut this Wednesday afternoon.
All that’s missing is SpaceX’s official confirmation. Boca Chica Village has already been evacuated and the company appears to be in the process of clearing the launch pad of personnel as of 2pm CDT – two hours into a window that closes around 8pm CDT (01:00 UTC, May 6). Stay tuned for a possible Starship launch later today!
Update: SpaceX has called off Starship SN15’s Tuesday, May 4th launch attempt for unknown reasons. The rocket is now scheduled to fly no earlier than (NET) Wednesday, May 5th – perhaps just ~24 hours after the company’s 25th operational Starlink launch.
Barring delays, SpaceX appears to be on track to launch a batch of 60 Starlink satellites and perform a fifth high-altitude Starship flight test mere hours apart on Tuesday, May 4th.
Around 1am on May 3rd, SpaceX completed a successful wet dress rehearsal (WDR) and static fire test with Falcon 9 booster B1049, an expendable upper stage, and the latest stack of Starlink satellites. Around eight hours later, as per usual, SpaceX confirmed via social media that the test was a success and that its 25th operational Starlink mission is scheduled to launch no earlier than 3:01 pm EDT (19:01 UTC) on Tuesday, May 4th.
-->Simultaneously, after a handful of delays, SpaceX also appears to be on track to attempt the first launch of a Starship with “hundreds of improvements” sometime between ~1pm and ~8pm CDT (18:00-01:00 UTC) on the same Tuesday.
Starlink-25 will be SpaceX’s second daylight Falcon 9 launch in months – rare as of late due to arcane specifics of the constellation’s orbital mechanics. Aside from generally offering a much better view of the launch, Starlink-25’s 3:01 pm EDT launch target means that Falcon 9 and Starship SN15 could technically launch at the exact same time in Florida and Texas.
While it’s unlikely if SpaceX would actually allow truly simultaneous launches and unclear if such a thing is even possible, it is possible that SpaceX could launch Starship SN15 at some point in the ~50 minutes Starlink-25 will be quietly coasting in orbit. More likely, though, SpaceX will use Starship SN15’s eight-hour window and wait until Starlink-25 is complete unless some kind of encroaching weather system shrinks that window to a few hours.
That still means that Starlink-25 and Starship SN15 could launch less than six hours apart, though it’s far more likely that the experimental rocket prototype will suffer minor delays and grow that gap to a day or two. Additionally, SpaceX itself cautions that it’s “keeping an eye on weather in the [Starlink-25] recovery area,” meaning that conditions at sea could also delay the Starlink launch a day or two.
Ultimately, it looks likely that both rockets will launch before the week is out. Stay tuned to find out just how ‘back to back’ they’ll actually be.

Tesla scores major hire as Apple scientist moves to Optimus team
Chen, who advanced from individual contributor to technical lead during his time at Apple, noted that he was blown away by Tesla’s efforts and synergy.
Former Apple research scientist Yilun Chen has left the tech giant to join Tesla’s Optimus AI team. Chen, who advanced from individual contributor to technical lead during his time at Apple, noted that he was blown away by Tesla’s efforts and synergy.
Apple veteran closes a major chapter
In a farewell note, Yilun Chen reflected on his tenure at Apple as a period defined by rapid growth and exposure to notable internal projects, some of which remain unreleased. His roles spanned engineering, research, early product incubation, and hands-on prototyping, allowing him to build expertise across both mature and emerging teams.
Chen credited mentors, colleagues, and cross-functional collaborators for shaping his trajectory, calling the experience unforgettable and emphasizing how each team taught him different lessons about scaling technology, guiding product vision, and navigating fast-moving research environments. “Each role has offered me invaluable unique lessons… My deepest gratitude goes to my colleagues, mentors and friends,” he wrote.
Tesla’s Optimus lab secured the hire
Chen said the move to Tesla was driven by the momentum surrounding Optimus, a humanoid robot powered by LLM-driven reasoning and Physical AI. After visiting Tesla’s Optimus lab, he admitted that he was “totally blown away by the scale and sophistication of the Optimus lab and deep dedication of people when I got to visit the office.”
His first week at Tesla, he noted, involved spontaneous deep-tech discussions, a flat team structure, rapid prototyping cycles, and what he called a “crazy ideas with super-fast iterations” culture. Chen emphasized that the team’s ambition, as well as its belief that humanoid robots are now within reach, creates an energy level that feels aimed at changing the world.
-->“You can feel the energy to change the world here,” he wrote in a post on social media.

Elon Musk gives nod to SpaceX’s massive, previously impossible feat
It was the booster’s 30th flight, a scenario that seemed impossible before SpaceX became a dominant force in spaceflight.
Elon Musk gave a nod to one of SpaceX’s most underrated feats today. Following the successful launch of the Transporter-15 mission, SpaceX seamlessly landed another Falcon 9 booster on a droneship in the middle of the ocean.
It was the booster’s 30th flight, a scenario that seemed impossible before SpaceX became a dominant force in spaceflight.
Elon Musk celebrates a veteran Falcon 9 booster’s feat
SpaceX completed another major milestone for its Smallsat Rideshare program on Friday, successfully launching and deploying 140 spacecraft aboard a Falcon 9 from Vandenberg Space Force Base. The mission, known as Transporter-15, lifted off two days later than planned after a scrub attributed to a ground systems issue, according to SpaceFlight Now. SpaceX confirmed that all payloads designed to separate from the rocket were deployed as planned.
The Falcon 9 used for this flight was booster B1071, one of SpaceX’s most heavily flown rockets. With its 30th mission completed, it becomes the second booster in SpaceX’s fleet to reach that milestone. B1071’s manifest includes five National Reconnaissance Office missions, NASA’s SWOT satellite, and several previous rideshare deployments, among others. Elon Musk celebrated the milestone on X, writing “30 flights of the same rocket!” in his post.
Skeptics once dismissed reusability as unfeasible
While rocket landings are routine for SpaceX today, that was not always the case. Industry veterans previously questioned whether reusable rockets could ever achieve meaningful cost savings or operational reliability, often citing the Space Shuttle’s partial reusability as evidence of failure.
-->In 2016, Orbital ATK’s Ben Goldberg argued during a panel that even if rockets could be reusable, they do not make a lot of sense. He took issue with Elon Musk’s claims at the time, Ars Technica reported, particularly when the SpaceX founder stated that fuel costs account for just a fraction of launch costs.
Goldberg noted that at most, studies showed only a 30% cost reduction for low-Earth orbit missions by using a reusable rocket. “You’re not going to get 100-fold. These numbers aren’t going to change by an order of magnitude. They’re just not. That’s the state of where we are today,” he said.
Former NASA official Dan Dumbacher, who oversaw the Space Launch System, expressed similar doubts in 2014, implying that if NASA couldn’t make full reusability viable, private firms like SpaceX faced steep odds.

Tesla AI and Autopilot VP hints that Robovan will have RV conversions
Tesla’s vice president of AI and Autopilot software, Ashok Elluswamy, hinted at the linitiative in a reply to Y Combinator CEO Garry Tan.
It appears that Tesla is indeed considering an RV in its future pipeline, though the vehicle that would be converted for the purpose would be quite interesting. This is, at least, as per recent comments by a Tesla executive on social media platform X.
Robovan as an RV
Tesla’s vice president of AI and Autopilot software, Ashok Elluswamy, hinted at the linitiative in a reply to Y Combinator CEO Garry Tan, who called for a startup to build RVs with Full Self-Driving capabilities. In his reply, Elluswamy simply stated “On it,” while including a photo of Tesla’s autonomous 20-seat people mover.
Tesla unveiled the Robovan in October 2024 at the “We, Robot” event. The vehicle lacks a steering wheel and features a low floor for spacious interiors. The vehicle, while eclipsed by the Cybercab in news headlines, still captured the imagination of many, as hinted at by X users posting AI-generated images of Robovan RV conversions with beds, kitchens and panoramic windows on social media platforms. One such render by Tesla enthusiast Mark Anthony reached over 300,000 views on X.
Elon Musk on the Robovan
Elon Musk addressed the Robovan’s low profile in October 2024, stating the van uses automatic load-leveling suspension that raises or lowers based on road conditions. The system maintains the futuristic look while handling uneven pavement, Musk wrote on X. The CEO also stated that the Robovan is designed to be very airy inside, which would be great for an RV.
“The view from the inside is one of extreme openness, with visibility in all directions, although it may appear otherwise from the outside. The unusually low ground clearance is achieved by having an automatic load-leveling suspension that raises or lowers, based on smooth or bumpy road conditions,” Musk stated.
-->Elluswamy’s response on X suggests that Tesla is considering a Robovan RV conversion, though it would be interesting to see how the company will make the vehicle capable of reaching campsites. The Robovan has a very low ground clearance, after all, and campsites tend to be in unpaved areas.
