SpaceX’s next Starlink launch will have to wait a bit longer
According to NASASpaceflight.com sources, SpaceX’s next Starlink satellite launch will have to wait a bit longer after slipping about a week from its former April 16th target.
Recently discussed on Teslarati, SpaceX has planned what is effectively a “return to flight” launch just weeks after Falcon 9 suffered its first in-flight engine failure in almost eight years. While the rocket was able to adjust on the fly to ensure that the overall Starlink mission was a success, the unprecedentedly reused Falcon 9 booster was lost during its landing attempt. More importantly, the Merlin 1D engine failure immediately raised the concern of NASA and the US military, SpaceX’s most important launch customers.
Expected to launch on thrice-flown Falcon 9 booster B1051, a successful return-to-flight so soon after SpaceX’s Starlink-5 anomaly would strongly imply that the company has already identified and characterized the cause of that March 18th hiccup with a significant degree of confidence. While Starlink-6 (the seventh Starlink launch overall) wont exactly replicate the conditions preceding Starlink-5’s in-flight engine failure, a successful launch would hopefully help alleviate any major concerns from SpaceX’s customers. That mission, however, will now have to wait another week or so to launch.
While not quite as flight-proven as B1048, the Falcon 9 booster that suffered an engine failure and was lost at sea last month, SpaceX (according to Next Spaceflight) has assigned Falcon 9 booster B1051 to its seventh Starlink launch. Since its first flight in March 2019, supporting Crew Dragon’s historic orbital launch debut, B1051 has completed two additional orbital-class launches and landings, lofting Canada’s three-satellite Radarsat Constellation Mission (RCM) in June 2019 and SpaceX’s fourth batch of 60 Starlink satellites in January 2020.
The Starlink-6 (Flight 7) mission will be B1051’s fourth, making it the sixth SpaceX Falcon 9 booster to launch four times since booster B1048 pushed the envelope in November 2019 – just five months ago. Aside from Falcon 9 B1048’s Starlink-5 engine failure and subsequently unsuccessful landing attempt, SpaceX also lost booster B1056 after its fourth flight in February 2020. Excluding two or three new Falcon 9 boosters assigned to critical missions for NASA and the US military, those two booster losses shrunk SpaceX’s rocket fleet by 30-40%, leaving just three flight-proven Falcon 9 boosters for other Starlink or customer missions.
SpaceX does have two twice-flown Falcon Heavy side boosters, said by CEO Elon Musk to be relatively easy to convert into Falcon 9 boosters, but their status is currently unknown, leaving them as the wildcards of SpaceX’s rocket fleet.
For SpaceX to be able to continue an ambitious Starlink launch cadence throughout the rest of 2020, the successful recovery of flight-proven boosters like B1051, B1049, and B1059 will likely be uniquely paramount over the next few months. Assuming SpaceX is able to successfully launch its first astronauts on Crew Dragon (NET late May) and complete a second US military GPS satellite launch (NET June 30th), two once-flown boosters will thankfully enter the company’s fleet, raising it to five (or seven) strong in by July or August.
SpaceX’s next Starlink launch is now scheduled for no earlier than (NET) April 22nd, give or take a day or two.

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.
