SpaceX’s first fairing catch imminent with plans to 4X Mr Steven’s net
Following SpaceX CEO Elon Musk’s brief confirmation that the launch company would be quadrupling recovery vessel Mr Steven’s already-huge net, members of the /r/SpaceX subreddit created a rough visualization of what that expanded net might look like once completed.
Based on rough estimates done by the author, SpaceX’s official confirmation that fairings had landed within 50 meters of Mr Steven’s net indicates that the parasailing halves are able to somewhat reliably reach Mr Steven’s net with a margin of error of roughly 0.01% when they really need 0.005% to be caught in the vessel’s net every time. Based on specifications from the vessel’s shipyard, his current claws appear to be roughly 75% the length of the entire vessel, or something like 40m long by 30 to 40m wide.

Several days after the author’s speculation was published, Mr. Musk appeared to effectively corroborate it by stating on Twitter that Mr Steven’s net would have its area expanded fourfold in order to operationalize fairing recovery: to quadruple the area, both the length and the width of the net would need to be expanded by a factor of two (square) or perhaps 50% width-wise and 150% lengthwise (more rectangular). Mr Steven’s massive steel arms appear to be fairly permanent in their current forms, suggesting that changing the aspect ratio of the net would be far more effort than simply expanding his arms along their current paths. Either way, lengthwise growth of a factor of 2-2.5 would appear to functionally close the gap on that 0.005% margin of error (the current 0.01% – missing by 50 meters – divided by 2 equals 0.005%) required, albeit by modifying the recovery vessel instead of optimizing the fairings’ hardware and software.
TL;DR: @SpaceX's fairing recovery engineers/techs have achieved a margin of error of like 0.01% when they actually need ~0.005% to reliably catch fairings in Mr Steven's net. Success is imminent 😀 https://t.co/MfPdzdBkyO

-->Put more simply, a net with four times the area would roughly halve the accuracy required from each fairing half for reliable recovery. Compared with the original (left) above, Reddit user Pipinpadiloxacopolis followed Musk’s rough estimation and did a rough Photoshop (right) of the fairing recovery vessel’s current arms, expanding it by 2X in each direction to arrive at a quadrupled area. Although I would argue that Mr Steven’s forward arms are unlikely to ever move beyond their current end-point around 10 meters behind the vessel’s crew cabin and cockpit, /u/Pipin’s estimate is probably a decent prediction for the upgraded vessel’s most likely appearance.
What’s less clear is whether the depth of the net will increase alongside the length and width, nor whether the already massive arms will have to rely on some sort of retraction/pivot mechanism to allow Mr Steven to safely maneuver within Port of Los Angeles waters. Regardless of the solution that SpaceX expertise arrives at, the already eclectic recovery vessel is all but guaranteed to look even more absurd and awesome than it already does. With any luck, the net expansion may allow SpaceX to finally achieve their first successful ‘catch’ of a Falcon fairing, ending the need for mass-storage of unreusable fairing halves grabbed off of the ocean surface.

Stay tuned, as Teslarati photographer Pauline Acalin will be tracking modifications made to Mr Steven closely over the next several weeks. As of now, the vessel will return to the Pacific Ocean for another fairing catch attempt sometime in the second or third week of July. We’ll find out soon whether Musk’s mentioned upgrades can be realized before then.

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.
