A SpaceX rocket just aced its seventh launch and landing for the first time
For the first time ever, a SpaceX Falcon 9 rocket booster has successfully completed seven orbital-class launches and landings, leaving the company as few as three flights away from achieving its longstanding reusability goal.
Ending two days of “mission assurance” and weather-related delays, Falcon 9 booster B1049.6, a new expendable upper stage (S2), two flight-proven fairing halves, and 60 Starlink v1.0 satellites lifted off at 9:13 pm EST on November 24th. As usual, the rocket appeared to perform flawlessly, sailing through main engine cut-off (MECO), second stage start (SES), and first stage reentry and landing. Falcon 9 successfully touched down on drone ship Of Course I Still Love You (OCISLY) around 8.5 minutes after liftoff, officially making booster B1049 the first to complete (and survive) seven orbital-class launches.
For SpaceX, the success means that the company now has a new rocket booster “fleet leader,” referring to the fact that B1049.7 will now serve as a reference point and treasure trove of data for other SpaceX rockets pushing towards the same reusability milestone. Reuse record aside, SpaceX’s flawless Starlink-15 launch also pushed the company passed an arguably equally – if not more – important operational milestone.
Specifically, November 2020 is now SpaceX’s first four-launch month ever, handing Falcon 9 an achievement that only a few rockets in history can lay claim to. Crucially, extrapolated out to a full calendar year, achieving four orbital launches in one month directly implies that SpaceX is well within reach of an annual cadence of 40 launches or more.
Coming just ~6 weeks after CEO Elon Musk revealed an ambitious target of 48 launches in 2021, SpaceX has certainly delivered its first four-launch month at the best possible time. Even if four-launch months are not immediately sustainable, the achievement brings significant confidence that SpaceX will be able to crush its already record-breaking 2020 launch cadence next year.
Technically, Starlink-15’s completion means that SpaceX has actually managed 4 launches in 19 days and 7 launches in the last ~50 days, representing an average of one launch every 4.75-7 days. Extrapolated over a full year, SpaceX has effectively demonstrated that its Falcon 9 infrastructure is already capable of achieving an annual cadence of 50-75 launches even if several technical bugs or weather delays arise every month.
Reusability is as essential as ever for SpaceX’s extremely ambitious launch cadence targets. The introduction of three new Falcon 9 boosters in just the last three weeks will almost certainly provide some relief to SpaceX’s hardworking rocket fleet while also offering even more capacity to strive towards an annual average of four or more launches per month. B1049 effectively opening up a new tier of reusability and taking SpaceX just three steps away from its original ten-flight reusability goal also serves as a force multiplier for the fleet, adding at least another seven launches of capacity.

Now eight boosters strong, SpaceX’s flight-proven Falcon 9 fleet could theoretically support a rough average of one launch per week, though the flight rate of three boosters (B1061, B1062, and B1063) will be somewhat handicapped due to their recent assignments to several major NASA and US military launches. Ultimately, while SpaceX has a plenty of work left in front of it, the company is well on its way to becoming the world’s most prolific and experienced launch provider by a healthy margin.

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.

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.
