SpaceX launches first Starlink mission of 2023 after eight delays
A Falcon 9 rocket has successfully launched SpaceX’s Starlink 2-4 mission after seven delays pushed it from November 2022 to January 2023.
Starlink 2-4 was originally scheduled to launch as early as November 18th, 2022, but was delayed shortly after its Falcon 9 rocket conducted a static fire test. The delay was indefinite, and that specific rocket ultimately launched a different commercial payload in late December. The internet satellite launch was finally rescheduled for January 9th, 2023, kicking off a string of additional delays. Weather delayed the January 9th attempt. Issues with Falcon 9’s second stage delayed the January 10th attempt. Additional “pre-launch checkouts” delayed the launch from January 11th to the 14th, which was then pushed to January 15th for “constellation optimization.“
Poor weather delayed Starlink 2-4 from January 15th to January 18th, and SpaceX eventually delayed the mission to January 19th without explanation. On January 19th, SpaceX even delayed Starlink 2-4 an eighth time, from 7:23 am PST to 7:43 am PST. But at long last, Starlink 2-4 did, in fact, lift off at 7:43 am PST, ending the longest streak of delays experienced by SpaceX in several years.

In a rare twist, the first delay caused SpaceX to shuffle booster assignments, and Starlink 2-4 wound up with B1075. B1075 had never flown before, making Starlink 2-4 the second Starlink mission that has debuted a new Falcon booster. Ordinarily, SpaceX has always reserved new boosters – of which only a handful are built annually – for its more conservative customers. The US military in particular was slow to warm up to the idea of flying operational “national security” payloads on reused Falcon boosters, and often required (and paid for) new boosters whenever possible.
But even that wall mostly crumbled in 2022. SpaceX debuting another new Falcon 9 booster on its own low-priority Starlink mission is perhaps the best evidence of that. NASA and the US military have simply come to trust SpaceX’s flight-proven Falcon boosters, and no longer feel the need to reserve every new Falcon 9.
-->Falcon 9 booster B1075 ultimately aced its orbital-class launch debut and touched down on drone ship Of Course I Still Love You (OCISLY) about nine minutes after liftoff. Assuming the seas are calm enough for B1075 to survive the return to Port of Long Beach, it likely has a long life of 15+ launches ahead of it. The Falcon upper stage launched by B1075 eventually reached low Earth orbit (LEO) and deployed another 51 Starlink V1.5 satellites about 30 minutes after liftoff. Starlink 2-4 should leave SpaceX with almost 3400 working Starlink satellites in orbit.
OCISLY gets an upgrade
B1075’s landing also revealed upgrades SpaceX has made to drone ship OCISLY since it was last used in October 2022. Harry Stranger first discovered the changes with satellite imagery, which revealed that SpaceX was upgrading OCISLY’s rectangular with angular ‘wings’. The wings appear to be identical to those installed on SpaceX’s newest drone ship, A Shortfall of Gravitas. ASOG debuted in mid-2021 with a number of upgrades not present on SpaceX’s two other drone ships. Most were intended to improve the ship’s resiliency, availability, and autonomy.
According to photographer Jerry Pike, the angular wings on ASOG (and now OCISLY) could make the drone ship much easier to tow. Reducing drag could also increase the effectiveness of their existing propulsion systems, potentially allowing them to maintain their position in harsher sea conditions and stronger currents than before. SpaceX CEO Elon Musk has previously stated that the ultimate goal is a fully-autonomous drone ship capable of heading to sea, recovering Falcon boosters, and returning to port without human intervention.
There is no evidence that SpaceX is any closer to that goal since ASOG’s debut 16 months ago. Nonetheless, OCISLY’s upgrades should improve the drone ship’s usability as SpaceX attempts to launch (and land) up to 100 rockets in 2023.

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.
