SpaceX aces three Falcon 9 launches in 34 hours
SpaceX has successfully launched three Falcon 9 rockets less than 34 hours apart, leaving the company only one mission shy of CEO Elon Musk’s ambitious target of 60 launches in 2022.
The period was almost even more intense, with two launches briefly scheduled minutes apart and all three set to launch in the space of 10-11 hours. But the more conservative sequencing SpaceX ultimately settled on still produced impressive results and allowed the company to break its own world record for the fastest time to complete three launches of the same rocket. In June 2022, SpaceX managed three similar launches – a Starlink mission, a scientific Earth observation satellite, and a commercial communications satellite – in 36 hours and 18 minutes.
Six months later, SpaceX has shaved more than two hours off of its own feat with the successful launches of another Earth observation satellite, a pair of commercial communications satellites, and 54 Starlink satellites in 33 hours and 46 minutes.

SpaceX’s latest hat trick began on December 16th with a Falcon 9 launch of the joint US-French Surface Water and Ocean Topography (SWOT) mission out of Vandenberg Space Force Base (VSFB), California. Delayed from December 12th and 15th, the launch was nonetheless a perfect success, placing the 2.2-ton (~4850 lb) radar satellite into a low Earth orbit that will allow it to precisely analyze virtually every inch of exposed water on Earth. That unprecedented capability should make it easier for scientists to study and understand Earth’s water cycle, as well as humanity’s substantial impact on those processes.
A little over 11 hours later, a second Falcon 9 rocket lifted off from SpaceX’s Cape Canaveral Space Force Station LC-40 pad carrying the first two Boeing-built O3b mPOWER satellites for satcom provider SES. Once again, SpaceX’s workhorse rocket did its job perfectly, even managing to exceed its contracted parameters according to SES CEO Steve Collar. Falcon 9’s better-than-expected performance will reduce the amount of time and propellant each 1.7-ton (~3750 lb) mPOWER satellite requires to reach its operational orbit, potentially ensuring a quicker path to revenue generation and longer useful lifespans.
-->SpaceX is on contract to launch all 11 initial mPOWER satellites. The next nine satellites will head to orbit sometime in 2023 and 2024 as Boeing completes them.
Finally, less than a day later after O3b mPOWER 1&2, a third Falcon 9 rocket lifted off from SpaceX’s NASA Kennedy Space Center LC-39A pad (just a few miles north of LC-40) with what could be the last full batch of “Group 4” Starlink V1.5 satellites. SpaceX’s first-generation Starlink constellation is comprised of five groups of satellites operating in distinct orbital ‘shells,’ and the company’s December 18th launch of Starlink 4-37 will leave SpaceX just 14 satellites away from fully finishing the second of two shells of 1584 satellites. All told, Starlink 4-37 was SpaceX’s 65th operational Starlink launch since November 2019 and the company likely has just ~20 launches to go to complete its first satellite constellation – already the largest in history by an order of magnitude.
All three launches were completed in less than a day and a half. Further emphasizing the breadth of SpaceX’s expertise, each Falcon 9 booster successfully landed after supporting their respective orbital launch, ensuring that those boosters will all be able to support more launches in the near future. In fact, Starlink 4-37 was the 15th mission for its Falcon 9 booster, B1058, breaking SpaceX’s internal reuse record and pushing the technology’s envelope. It remains to be seen if the company will push beyond 15 flights. In June 2022 interviews with Aviation Week, SpaceX executives stated that Falcon boosters would be retired after 15 flights – a big change from past indications that there was nothing preventing each booster from launching 100+ times with regular maintenance.
Starlink 4-37 was also SpaceX’s 59th successful orbital launch of 2022. In March, CEO Elon Musk raised an earlier annual target of 52 launches to 60 launches. At the time, 60 launches in one year was almost inconceivable. Set in 1980, the all-time record for a family of rockets (the Russian R-7) is 61 successful launches in one calendar year.
But against all odds, SpaceX has relentlessly executed week after week and sustained an average of one launch every six days for more than 12 months. Multiple sources currently indicate that SpaceX has two more Falcon 9 launches scheduled this year: another Starlink mission as early as December 28th and a mission carrying the Israeli EROS-C3 Earth imaging satellite on December 29th. SpaceX’s Falcon rocket family thus has a chance to tie the all-time record of 61 R-7 family launches, which was backed by the entire Soviet Union at the peak of its national launch cadence.

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.
-->“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.
