SpaceX reveals Falcon fairing recovery progress as Mr. Steven barely misses catch
SpaceX has offered an extraordinary glimpse into a stealthy program of Falcon fairing recovery research and development, which has utilized drop tests and iterative hardware and software upgrades to inch ever closer to fairing reuse over the last 6-9 months.
Short of a small handful of sparse comments made by executives in 2018, this is the first time SpaceX has officially acknowledged its continued attempts to optimize Falcon fairing recovery in the face of a number of missed post-launch catches. Given that the pictured fairing was so close to a successful landing that its parafoil actually became caught in Mr. Steven’s net, it seems that SpaceX has nearly solved the problems that have thus far prevented program success.

In the last six months of 2018, SpaceX has continued to tease its slow progress towards reusable Falcon fairings, originally planned to depend on a truly bizarre solution – Mr. Steven. An impressive vessel on its own, SpaceX has gradually added and extended and upgraded a range of recovery hardware on his deck, most notably including a vast net (likely tens of thousands of square feet or 2000+ square meters) supported by four huge arms and eight supporting booms. Despite increasing the usable area of the net, SpaceX has been unable to secure an operational fairing catch since it began attempts in March 2018.
-->In late May 2018, SpaceX provided the best look yet at the actual process of recovering Falcon fairings, showing off the guided parafoil (a wing-like parachute) and revealing that a fairing half – launched in support of Iridium-6/GRACE-FO – had splashed down just 50 meters (~165 ft) away from Mr. Steven’s net.
Falcon 9 fairing halves deployed their parafoils and splashed down in the Pacific Ocean last week after the launch of Iridium-6/GRACE-FO. Closest half was ~50m from SpaceX’s recovery ship, Mr. Steven. https://t.co/JS7d5zTdIg pic.twitter.com/LjiTwnB4wd

However, in the months that followed, info about catch attempts became increasingly sparse and it eventually became clear that SpaceX was preparing to perform a range of controlled drop tests a few hundred miles off the coast of California. Ultimately, the company’s engineers and technicians hoped to use the controlled environment and a greater number of available drop/catch attempts to refine the hardware and software needed to finesse fairing halves into Mr. Steven’s net.
It may be almost absurdly large relative to any other conceivable thing that exists in the real world, but a few thousand square meters is actually more like a needle in a haystack for a piece of rocket traversing a 500-800 km arc at top speeds of more than 2 km/s.

In December 2018, following another sadly unsuccessful fairing recovery attempt on the West Coast, SpaceX CEO Elon Musk revealed that engineers were also apparently looking into backup plans in case closing that last 50-meter gap turned out to be more expensive or complicated than it was worth. Most notably, he implied that SpaceX was interested in finding ways to waterproof and ultimately refly Falcon fairings even after soft-landings in seawater, whereas fairings are already capable of reliably landing intact in the ocean but cannot be reused due to seawater contamination and cracking caused by impact.
Falcon fairing halves missed the net, but touched down softly in the water. Mr Steven is picking them up. Plan is to dry them out & launch again. Nothing wrong with a little swim.

Given just how close Mr. Steven appears to be to a successful in-net fairing recovery, it now seems implausible that SpaceX will choose just one of the two options at hand, likely instead progressing both development programs to points of success. Once fairings can both be successfully waterproofed and caught in Mr. Steven’s net, SpaceX will almost certainly have itself a foolproof solution to easy and reliable recovery and reuse even in bad sea states and stormy weather.
-->With the company’s first launch of 2019 probably just a few days away, chances seem good that SpaceX will attempt at least one more post-launch fairing recovery with Mr. Steven. Fingers crossed!

Tesla Semi factory looks almost complete during Thanksgiving weekend
Based on recent drone videos, the Tesla Semi factory looks practically ready to start operations.
It appears that the Tesla Semi factory near Giga Nevada is already hard at work preparing for the initial production of the Class 8 all-electric truck. This was, at least, hinted at in a recent drone flyover of the facility from a longtime watcher.
The Tesla Semi factory after Thanksgiving
Drone operator and Tesla Semi advocate @HinrichsZane recently shared some footage he captured of the upcoming facility during the Thanksgiving weekend. Based on his video, it appears that Tesla gave its employees in the area the weekend off. One thing is evident from the video, however, and that is the fact that the Tesla Semi factory looks practically ready to start operations.
The Tesla Semi watcher did point out that the electric vehicle maker is still busy bringing in production equipment into the facility itself. Once these are installed, it would not be surprising if initial production of the Tesla Semi begins.
A new Tesla Semi
The upcoming completion of the Tesla Semi factory near Gigafactory Nevada seems all but inevitable in the coming months. What would be especially interesting, however, would be the vehicles that would be produced on the site. During Elon Musk’s presentation at the 2025 Annual Shareholder Meeting, a glimpse of the production Tesla Semi was shown, and it looks quite a bit different than the Class 8 all-electric truck’s classic appearance.
As could be seen in the graphic from the CEO’s presentation, the updated Tesla Semi will feature slim lightbar headlights similar to the new Tesla Model Y, Cybertruck, and the Cybercab. Tesla also teased a number of aerodynamic improvements that increased the truck’s efficiency to 1.7 kWh per mile. Extended camera units, seemingly for FSD, could also be seen in the graphic.

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.

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.
